1 General Introduction 1.1 Project Background 1.1.1 Need of the Project Bayannaoer City is located in the west of North China’s frontier province, Inner Mongolia Autonomous Region�within the range between 105°12 ~109°53 E and 40°13 ~42°28 N. It is bordered by Baotou City and Ulanqab City to the east, by Alashan League to the west and by the Ikchor with the Yellow River and by the People's Republic of Mongolia with a national boundary of 368.89km long. The Bayannaoer city, 378km long from east to west and 238km wide from north to south, covers an area of 65,788km2. Its administrative divisions include 4 banners, 2 counties and 1 district such as Wulate Front Banner, Wulate Middle Banner, Wulate Back Banner, Hangjinhouqi County, Wuyuan County and Dengkou County. Its core area is the Hetao Irrigation District. Approved by the State Council at the end of 2000, the city was raised to a prefecture-level city. According to the strategies for economic development of the Inner Mongolia Autonomous Region and Bayannaoer City, the economic development will be based on the establishment of industrial parks to make the best use of the abundant mineral resources in the city and Mongolia. Such projects have been planned to establish Qingshan Industrial Park, Jinquan Industrial Park, Shahai Industrial Park, Linhe Chemical Industrial Park and Wulate Industrial Base. Thus Bayannaoer will be a key heavy chemical industry base in Inner Mongolia Autonomous Region. The total industrial water demand for its perspective long-term plan will reach about 520,000,000m3/a. The water demand for long-term plan of such industrial parks in the area along the mountains where water shortage is very acute is about 410,000,000 m3. According to the estimates of Water Resource Comprehensive Planning Report of Bayannaoer of Inner Mongolia Autonomous Region, the gross amount of water resources at the southern foot of Yishan Moutain in Yellow River Basin within Bayannaoer city is 587,000,000m3, where ground water resource, totaling 380,000,000m3, mainly serve as domestic water for urban and rural residents. In line with the state’s relevant industrial policies, industrial water is mainly subject to reclaimedwater. With 293km2 water surface and about 330,000,000m3 total storage capacity, Wuliangsuhai Lake is the largest riverside freshwater lake on the middle - upper stream of the Yellow River. With the development of industrial production and increase in town populations in the irrigation district, industrial wastewater and municipal domestic wastewater are increasing year by year, the pollution of main drainage canal is getting worse. Eutrophication in Wuliangsuhai Lake in particular is getting worse. Accordingly, total phosphorus and nitrogen and COD in the lake exceed 3~5 times the national category-3 standard for surface water quality. The water quality is worse than Grade V. The biological sedimentation speed in the lake is accelerating, leading to the degradation of its ecological functions. Moreover, before the flood period each year, to reserve enough flood storage capacity, it is necessary to take off the check gate at the exit section of main drain to discharge the water to the Yellow River. As such, the large amounts of wastewater storaed in the lake may offer threat of serious pollution to the Yellow River.

To further promote comprehensive improvement of water environment in Bayannaoer city, exert more efforts to strengthen infrastructure service, reduce pollution load into Wuliangsuhai Lake, slow down environmental degradation, improve the quality of urban water environment and further advance urbanization process and economic growth, Bayannaoer municipal Party Committee and municipal government decided to cooperate with the Word Bank so as to make use of World Bank loans to implement the Bayannaoer Water Reclamation and Environemnt Improvement Project (hereafter refer to “the Project”).. With extensive preliminary investigation and elaborate preparations, Bayannaoer submitted a formal application to the State Development and Reform Commission in August 2006 for World Bank load of 150,000,000 dollars (totaling about 2.125 billion RMB with counterpart funds) to implement the Bayannaoer Water Reclamation and Environemnt Improvement Project (hereinafter called The Project). This application was approved in July, 2009 and was listed in the China Alternative Project Planning in 2010-2012 Fiscal Year by Use of World Bank Loan. 1.1.2 Project Objectives The Project is intended to improve the quality of water environment in Bayannaoer city, make reasonable regulation and storage of water resources and promote the sustainable development of eco-environment and economy through the Project. 1.1.3 Relevant Policies and Regulations y Chinese Relevant Policies and Regulations

The reclaimed water supply and wastewater treatment and reuse works are classified into the comprehensive utilization and treatment works for “brackish water, poor quality water and sea water exploitation and utilization works” and “three wastes” that are encouraged by guidance of national industrial restructuring (2005 edition)..

Wuliangsuhai lake is an important natural reserve of Inner Mongolia Autonomous Region. According to the Regulations on the Nature Protection Regions of the People’s Republic of China, core area is prohibited from entrance and any types of development, the buffer zone of the natural reserve is not allowed for development of production works. However, This project is of water environment treatment works aiming at improving the water environment quality and ecological conditions of Wuliangsuhai lake, protecting and restoring its wetland functions. The project will avoid constructing in core area but in buffer zone and experimental area. According to the Circular of the of the General Office of the State Council on Intensifying Wetland Protection and Management (GBF [2004] No.50), importance shall be attached to the strengthening of wetland protection and restoring of function. Therefore, the Wuliangsuhai lake treatment Works is in accordance with the national relevant laws and regulations. To sum up, this project meets the requirements of national relevant industrial policies, laws and regulations.

y World Bank Safeguard Policies

The implementation of wastewater treatment and reuse and reclaimed water supply works, especially the Wuliangsuhai lake works will reduce the pollutantion loads into the Wuliangsuhai lake, so as to improve its water environment quality, improve and protect its aquatic environment and restore its nature reserve function. According to the World Bank Safeguard Policies (OP 4.01, 4.04), the World Bank encourages the restoration and protection of natural habitat and its functions. The World Bank has been supporting and expecting the borrower to adopt defensive measures on natural resource management to ensure the sustainable development of environment. It has also initiated and supported the protection and land-improvement activities for natural habitat and provided funds for the natural habitat and ecological function protection programs which are favorable to the national and local development. The World Bank has also further initiated the restoring and reconstruction works on the deteriorative natural habitat. Therefore, this project meets the environmental assessment policies of World Bank for loaning program.

1.1.4 Relevant Planning of Environmental Protection Strategies 1) National Economic Development Program During the “11th Five-Year” period, the overall requirements of Bayannaoer for economic and social development are to take Deng Xiaoping Theory and the important thought of “Three Represents" as guidance, lead economic and social development by scientific concept of development. make further reform and deepen opening-up policies, make further implementation of rejuvenating and prospering the market by science, technology and talents, accelerate economical transition, adjust economic structure, change economic growth methods, speed up industrialization and urbanization process, promote the construction of socialism new rural and pastoral areas, increase infrastructure and ecological environment construction, establish Chinese western green agricultural and animal products and non-ferrous metals industry production and opening-up to the North bases, establish important hinges linking North China and North west, insist on people-oriented, make overall development of social undertakings, improve community services, better social security and assistance mechanism, make all efforts to maintain social stability, accelerate the overall construction of affluent society and try hard to build a prosperous, civilized, ecological and harmonious Bayannaoer. The macroeconomic development strategy of Bayannaoer is to achieve the ecological environment protection and sustainable development. The strategy is centered on the green agriculture and animal husbandry that will be enhanced by deep processing of agricultural and animal products. The new type industrialization of mining and smelting industries will be established. During the “11th Five-Year” period, one of the main objective of economic and social development of Bayannaoer is to make achievements in environmental protection and construction, including the further improved ecological environment, above 15% forest coverage rate, Class � country level of atmospheric environment, qualified water environment, 90% qualified discharge standard of “Three Waste” and 40% comprehensive utilization rate. The Plan has put forward an objective to build a resource-saving and environmental-friendly society by integrating water resources, making unified planning of Yellow River, surface water, underground water and rain water and trying hard to realize the cyclic utilization of water resources. It has also request the whole city to center on water resources optimal allocation, insist on broadening sources of incoming and reducing expenditure on reasonable utilization of water resources, deepen water right displacement, positively explore the water consumption modes of along-mountain industrial enterprise from Wuliangsuhai lake and main Drainage Canal, promote water saving in cities, make full use of the treated water and Yellow River ice flood and flood diversion water, make reasonable use of lake, sea, reservoir and running off water under the premise of un-destroying wetland ecological environment and attach importance to protect industrial water. On the other hand, the city is request to intensity water environment protection and treatment, plan drinking water protection area, strictly implement the water quality control standard for drinking-water source Carry out industrial discharge license system, achieve more than 90% pass rate of industrial waste water, attach importance to treat papermaking, brewing and smelting pollution, consolidating achievements, improve urban wastewater treatment

ratio, intensity comprehensive treatment of agricultural area source pollution, reduce application of fertilizer and pesticide, strengthen the construction of urban wastewater treatment facilities and supporting pipelines, gradually reach the industrial and domestic wastewater discharge standard, cut off pollution source of Yellow River and underground water, plan Wuliangsuhai lake treatment Works, implement urban roads, pipelines, water supply and discharge, refuse treatment and wastewater treatment programs taking all these as the important programs during the “11th Five-Year Plan” period. To sum up, the construction of this project is an important part of Bayannaoer Municipal National Economic and Social Development Program, which is of great importance to the realization of planned environmental protection objectives and in accordance with the requirements for development. 2) Urban Master Planning The general objective and strategy of the Bayannaoer master planning are: to speed up the process of urbanization, to enhance the core competitiveness of the city, to actively support by coordinated action the development strategy fit to the regional situation of Inner Mongolia Autonomous Region, and to build Bayannaoer City into a medium-sized city with increasingly integrated services, making it a Hetao garden city with continually developing economy, evolving society, and excellent maintaining environment. The Bayannaoer master planning puts the protection of ecological environment at the first place, basically realizing ecologization and garden style. The green coverage of the city shall get up to more than 35%, and the urban per capita public green space 19m 2. These are the objectives and strategy of the environmental development of Bayannaoer City. Development and construction activities aiming to non-agricultural nature under city regional planning of the outside of city proper in the Bayannaoer master plan divide the Bayannaoer space into three land use types, namely rigid control developing area, limited control developing area, and developing construction area. Rigid control developing area can be proximately regarded as non-allowable construction area, including: �First-grade basic farmland protection areas and first-grade basic pasture designated in Overall Plan of Land Utilization; � existing and planning natural reserves designated in Conservation Development Plan; � Water protection area specified in Over City Plan; � cultural heritages and historical and cultural sites under government protection, etc. designated by Cultural Relics Protection Department; � Other non-allowable construction control areas and important green areas for environmental protection, etc. along both sides of the nation highway or provincial highway; Developing construction area is mainly city(town) planning construction land scope confirmed by the general planning of various levels of city(or town), and the scope of use of land in construction like independent industrial and mining sites and major regional infrastructure, public social service facilities approved of the development and construction by the planning, land and other related administrative departments, non-agricultural development and construction activities approved by the law are allowed and encouraged in development construction areas; strictly control areas outside the development areas and the development construction areas as limited control development area, can do moderate village and town constructions and non-agricultural constructions under the control of strict policy and planning. Any non-agricultural development construction activities in limited control development areas are subject to careful legal procedures. The site selections of both resurgent water supply project and wastewater treatment and recycling project of this project are not in strict control development area, and The Wuliangsuhai lake area treatment project is an environment treatment project aiming at improving the sea area water environment, not belongs to production construction development activity. The water resources planning of Bayannaoer master planning regard adjusting water structure, developing water-saving agriculture, reducing agricultural water use to replenish industrial water use, actively developing wastewater treatment and reclaimed water recycling, relieving and avoiding the vicious cycle of scarcity of clean water as the planning principles. It also levies charge for water resources on agricultural exploitation of groundwater in irrigation areas, and maintains the balance of groundwater resources by the use of price leverage. The layout of industry should consider the actual situation of water resources. Meanwhile, large high-water-consumption industries are not encouraged to develop. Efforts shall be made to increase the recycling rate of industrial water use, so as to realize the harmony and sustainable development of industry and water resource. It puts forward active wastewater treatment and recycles wastewater, aiming to establish wastewater treatment factories in each county and each town and realizing wastewater reuse to replenish industrial water use and landscape water use, so as to release the increasingly tense water use conflict. The environmental protection objectives of Bayannaoer master planning is to bring the environment pollution and ecological deterioration fully under control, completely realize the discharge standards of pollutants, and enter a virtuous cycles of ecological systems. Thereinto, the atmosphere quality should stay at the national secondary standard. Among the quality of surface water environment, the water quality of the Yellow River and its irrigation channels should reach the National Surface Water Standard Class III, Wuliangsuhai lake, the main drain and arterial drainage should reach National Standard Grade IV, realizing the sustainable development of social economy and ecological environment. Such areas as Yellow River, Wuliangsuhai lake, Ural Mountains National Forest Park, Nudengsuosuolin Natural Reserve, water and soil erosion area, prairie desertification and degradation area, Ulan Buh desertification area

4

and Hetao secondary salinization area, the urban area and all counties shall be regarded as key areas of environment protection. Efforts shall be focused on the pollution prevention and ecological environment protection of the Yellow River and Wuliangsuhai lake. Efforts shall be also made to speed up the construction of waste water treatment factories in each county, controlling industrial pollution sources along the banks and achieving standard discharge of domestic and industrial wastewater. Pollution shall be controlled in terms of sources. Comprehensive renovation shall be imposed on Wuliangsuhai lake. Great efforts shall be made to plant trees and grass, make a good job in water and soil conservation and restore natural ecology. The regional pollution emission shall be subject to strict control. Long-term effective management measures among industrial enterprises shall be carried out. Water quality of irrigation channels from Yellow River and wastewater discharged into Wuliangsuhai lake shall be under strict control so as to make wastewater treatment rate to reach 100%, ensuring the water quality of Yellow River to reach National Surface Water Standard Class III. In sum, the sites selection of all works of the comprehensive control project of the Bayannaoer water environment by World Bank loans is in accordance with the requirements of the urban master planning and city regional planning, and it is also an important measure to accomplish city goals, water resource allocation and environment protection goals of Bayannaoer master planning and city regional planning. Therefore, the project accords with the Bayannaoer master planning and the city regional plan. 3) Land Use Planning The land use type of this project’s reclaimed water supply works and wastewater treatment plant site is waste land, unused land and processing park construction land respectively, none of which is in the strictly controlled development area. Therefore, the works construction of this project meets the land use planning of Bayannaoer. 4) Environmental Protection Planning Water environment protection objectives of Bayannaoer include: urban drinking water quality shall meet the sanitary standard for drinking water; water quality of the Yellow River Bayannaoer League section: water at the boundary section shall meet the class � standard of the national Environmental Quality Standard for Surface Water; water quality of Wuliangsuhai Lake shall meet the class � standard of the national Environmental Quality Standard for Surface Water; water quality of the main drain and other Drainage Canals shall meet the class � standard of the national Environmental Quality Standard for Surface Water;

The “11th Five-Year” planning objectives of environmental protection are determined as follows: by 2010, the development trend of environmental pollution and ecological damage shall reduce, urban lake water pollution and atmospheric environment pollution shall be reduced, urban environmental infrastructural construction shall be greatly improved; realize the total amount control objective of pollutants. The total amount control objective of water pollutants shall be as follows: COD shall be controlled within 40,000 t/a and the ammonia nitrogen within 2,000 t/a. Water pollution control measures to be adopted during the period of “11th Five-Year Plan” are mainly as follows: y Establish and implement the water pollution control planning on each Drainage Canal, main drain and

Wuliangsuhai Lake with the focus on improving the water environmental quality of river reaches in key cities and towns. Slow down lake sedimentation and effectively control pollution and eutrophication trend.

This project is an integral part of the environmental protection planning of Bayannaoer, which can effectively promote the comprehensive control of Bayannaoer water environment, especially the quality improvement of Wuliangsuhai Lake water environment. 1.2 Assessment Purposes According to the regulations of China Environmental Influence Assessment Law, Regulations on the Administration of Construction Project Environmental Protection and Notice on the Strengthening of Administration on the Environmental Impact Assessment of Construction Projects Using Loans from International Financial Organizations and the requirements of World Bank’s Safeguard Policies, as well as domestic and World Bank’s environmental impact assessment procedure, the environmental impact assessment on this project will reach the following main purposes: y Through data analysis, field survey and monitoring, and necessary modeling and analogy analysis, to make a

comprehensive assessment on the background situation of environment in the assessment areas, to determine the main existing environmental problems, provide background information for the prediction and assessment of the degree and range of the environmental impact as well as the future final acceptance of projects.

y Through field survey and analogy analysis, to identify the environmental impact factors during the construction and the operation of projects, to determine the parameters of primary pollution sources.

y Through the adopting of model simulation, analogy survey and other technical means, to predict and assess the impact degree and range of the projects on the ambient air water environment, soil, ecological environment, noise and social environment in the assessment areas.

y In accordance with the requirements of relevant laws, regulations and technical specifications, combining with the characteristics of local natural and social environment, propose and stipulate the protective measures which shall be adopted to reduce environmental impact.

y Through the assessment of this project, to propose specific and effective mitigation measures and environmental management plan, so as to provide basis for the supervision by independent institutions, also to provide scientific basis for the construction, operation, environmental management and environmental pollution prevention of water environment comprehensive control project, minimize the adverse impacts of project construction on surrounding environment, maximize the social environmental benefit, achieve the coordination and unification of economic, social and environmental benefits.

y This environmental impact assessment not only focuses on the analysis of water environment improvement of Wuliangsuhai Lake, but also considers the feasibility analysis on water resources allotment of the project; not only considers the impact of this project, but will consider the combined influence of the projects having been built, under construction and planned to be implemented in the next few years.

1.3 Assessment Grade and Key Points 1.3.1 Assessment Grade According to the regulations of the Notice on the Strengthening of Administration on the Environmental Impact Assessment of Construction Projects Using Loans from International Financial Organizations (HJ[1993] No. 324) of State Environmental Protection Administration of China and other ministries and commissions as well as the World Bank’s Safeguard Policies OP4.01 Environmental Assessment, , the environmental assessment category of this project is determined as Category A. The assessment grade is determined according to the Technical Guidelines for Environmental Impact Assessment (HJ/T2.1-93, HJ2.2-2008, HJ/T 2.3-93, HJ/T2.4-1995 and HJ/T19-1997). (Expressed in the form of table) (1) Surface Water Environment

6

According to the surface water environmental impact assessment classification of HJ/T2.3-93 Technical Guidelines for Environmental Impact Assessment—Surface Water Environment, the assessment grade is determined by the following four factors: wastewater discharge of the construction project, complexity of wastewater quality, scale of surface water area and surface water quality requirements. The surface water environment assessment grades of this project are as follows: because there is no wastewater discharged in the processing park wastewater treatment and reuse works of this project, only a brief analysis will be made on the water environmental impact of such works; the tail water discharge amount of reclaimed water supply works is small, the water quality is simple and the tail water is discharged into the class �water body of surface water, the assessment grade is determined as Grade � and qualitative assessment will be made on the water environmental impact of such works; the assessment grade of Wuliangsuhai Lake sea area control works is difficult to be directly judged according to the four factors alone. The pollutant source is mainly the pollutants discharge during the construction period. In view of the special properties of Wuliangsuhai Lake, the project scale is large and the involvement aspect is broad. Therefore, the assessment grade is determined as Grade � of surface water environmental impact assessment. (2) Ecology The reclaimed water supply works and the processing park wastewater treatment and reuse works of this project have very small range of influence, also very small impact on the ecological environment, therefore, only a brief analysis will be made on the ecological environment impact of these two types of works; the sea area control works of Wuliangsuhai Lake is environmental treatment works itself and its environmental impact is mainly the environmental impact during the construction period, which is temporary, short-term and will gradually disappear as the construction is completed. Therefore, the ecological environment assessment grade of this project is determined as Grade �.

(3) Ambient Air The impacts of this project on atmospheric environment mainly include the dust emission during the construction period and the offensive odor during the operation period of the processing park wastewater treatment and reuse works as well as the reclaimed water supply works. This project will adopt biological deodorization after the collection of the offensive odor caused during the operation period, which has small discharge amount; in addition, there are very few environmental objects around each works. Therefore, the atmospheric environment assessment grade of all works of this project is determined as Grade � and only qualitative assessment will be made.

(4) Acoustic Environment The impacts of this project on acoustic environment mainly include the construction machinery and traffic noises during the construction period of each works and the power equipment operating noise during the operation period of the processing park wastewater treatment and reuse works as well as the reclaimed water supply works. Consider that the noise impact during the construction period is short-term behavior, and during the operation period, the site selection of the wastewater treatment and reuse works as well as the reclaimed water supply works avoids the densely populated residential areas, hospitals, schools and other sensitive points. Therefore, the acoustic environment assessment grade of all works of this project is determined as Grade � and only qualitative assessment will be made.

1.3.2 Assessment Key Points The assessment of this project includes the construction period and operation period. The assessment key points of the construction period are as follows: (1) Wuliangsuhai Lake sediment and ecological environment impact; (2) Environmental impact and mitigation measures of pollution during the construction period. The assessment key points of the operation period are as follows: (1) The quality improvement of Wuliangsuhai Lake water environment after the project is put into operation and the accumulative impacts of effluent discharge into Wuliangsuhai Lake. This part includes 3 main aspects:

y Accumulative impacts on Wuliangsuhai Lake water quality after completion of the project; y Impacts on the growing and reproduction condition changes of terrestrial life and aquatic life and the impacts

on aquatic resources, breeding and fishery production before and after completion of the project; y Impacts of single subproject on Wuliangsuhai Lake water quality during the operation.

(2) Environmental impact mitigation measures and environmental management plan during the operation period of the project. (3) The impacts and mitigation measures of sludge in the processing park wastewater treatment and reuse works, reclaimed water supply works and the dredged sediment in grid waterway.

According to the requirements of Construction Standards for Municipal Wastewater Treatment Engineering Projects of the Ministry of Construction, the treatment & production facilities of wastewater & sludge resulting in odor shall be located in the downwind direction in summer in the auxiliary production areas of wastewater treatment plant, far from residential zones outside the plant as much as possible, and in accordance with relevant national regulations. If not meet the requirements, the distance of odor arising from production facilities between the wastewater treatment plant and residential zones outside the plant should not be less than 50 ~ 100 meters. 1.6 Environmental Impact Factors 1.6.1 Identification of Environmental impact Factors The implementation of this project will help to reduce the pollution load of Wuliangsuhai as well as improve its water environment, which is important not only for the promotion of comprehensive and sustainable development of

16

Bayannaoer’s environment and social economy, but also for the protection of water ecological environment security of the Yellow River. At the same time, during the construction and operation, the implementation of this project may also have some adverse environmental impacts on the social environment, ecological environment and environmental quality. On the design stage, the site selection, selection and comparison of technical schemes, feasibility studies and other works shall be carried out mainly, which won’t directly have some adverse impacts on the environment in general. The impacts during the construction and operation mainly include: y Social and environmental impacts:The implementation of this project will inevitably bring the socio-economic

impacts on the project area, mainly including the impacts of land acquisition and demolition. This project will involve four administrative villages of four towns (streets) of five banners (counties) of Bayannaoer, a state-owned farm as well as a state-owned pasture, in which 22 rural residents of 5 families will be affected by land acquisition, who are the affected population not dismantled arising from land acquisition. This project does not involve the houses to be dismantled, with the collection and temporary acquisition of various land of 3597.25 mu, including 758.00 mu of collecting land, 2839.25 mu of temporary land and150 scattered fruit trees, in which the land with an area of about 50.5ha will be occupied for the project construction, and then about 22 people will be affected by the project construction.

The issues of land acquisition, demolition and resettlement caused by this would affect the daily lives of local residents, resulting in changing their possession quantity of means of production and subsistence; the construction for roads and wastewater pipe networks would also affect the travel and security of residents along the line, as well as traffic conditions, etc..

y Impacts on ecological environment:As for the occupation of land for project construction, the local total arable land and vegetation quantity will be reduced, changing the nature of land use, causing the impact on the local agricultural ecology; destroying the vegetation on the project proposed site during the construction; easily resulting in the soil erosion due to inadequate protection on the high filled and deep excavated sections, earthwork filled and excavated sections as well as temporary piling sections, etc.; impacting on the Wuliangsuhai aquatic life due to the release of pollutants from bottom sludge during the construction for grid channel excavation engineering in Wuliangsuhai Sea Area.

y Impacts on environmental quality:

During construction: The nearby water bodies may be polluted by the running, spilling, dripping and leaking grease/oil stains from construction machinery as well as domestic wastewater caused by construction workers, and the release of pollutants from bottom sludge during the construction for grid channel excavation engineering in Wuliangsuhai Sea Area will impact on the water quality of Wuliangsuhai; the ambient air will be polluted by a great amount of dust generated in the material transport and mixing processes; the mechanical noise will also impact on the normal work and living of residents nearby construction site; the running frequently construction vehicles will impact on the existing traffic order. During operation: To some extent, the surrounding environment will be polluted as well due to the odor waste gas giving out during the wastewater treatment and reuse engineerings as well as the tail water discharged during the reclaimed water supply engineering in the Processing Industrial Park; for the drainage during the wetland engineering in artificial filter areas,due to the reduction of quantity of pollutants discharged into Wuliangsuhai, the water environmental quality of Wuliangsuhai will be significantly improved. Since the local engineering needs to be consolidated and maintained and the vegetation still needs some time to be recovered, the phenomenon of soil erosion will still exist for a period of time after the construction period.

In summary, the main existing impact factors of this project during construction and operation include: y Social environment: Land occupation, demolition, relocation and resettlement, road traffic as well as urban

appearance and landscape, etc.; y Ecological environment: Changing the impacts on the water ecological environment due to the land use condition,

vegetation destruction, soil erosion and grid channel excavation, etc.; y Water environment: The the release of pollutants from bottom sludge for grid excavation, domestic wastewater

and road runoff during construction; the production wastewater and living wastewater during operation, etc.; y Noise environment: The traffic noise and machinery noise, etc.; y Ambient air: Dust and exhaust pollutants arising from transport vehicles as well as odor produced by piling up and

transporting the bottom sludge for grid excavation during construction; the foul gas generated from the wastewater treatment and reuse engineerings in the Processing Industrial Park during operation, etc..

Effluent quality of 7th Drainage Canal is better and reaches the class-II wastewater discharge standard of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB18918-2002). According to the monitoring data of raw water quality of 7th Drainage Canal, the water quality of 7th Drainage Canal is worse in 1999 through 2006, and COD, Ammonia, TN, salt content and TP have far exceeded the standard. The main reasons are that the wastewater treatment plant of Draiange Canal 7 has not yet been built and the urban domestic and industrial wastewater of Wuyuan County is directly discharged into 7th Drainage Canal. �Ganqimaodu Processing park Reclaimed Water Project Analysis result of water quality of General Drainage Canal is shown in Table 3.2-21.

3.2.2.3 Processing plan on wastewater treatment and renovated water 1) the process flow of wastewater treatment and renovated water.

According to the requirements for inflow and outflow water quality of this sub-project, it is recommended that A/A/O process be selected for the secondary treatment, and for renovated water treatment, a three-stage process of coagulation – sedimentation – filtration shall be adopted. See Figure 3.2-2 for the process flow of wastewater treatment and renovated water. 2) Other processes y� Chlorine dioxide sterilizing method is adopted for sterilization process. For pathogenic microbe,

the extermination capacity of chlorine dioxide is higher than chlorine. As it does not react with ammonia, it can be provided with high sterilizing power even though under alkaline condition, and it can exterminate alga. Simultaneously, chlorine dioxide can cause high oxidization effect and can remove chroma in water favorably, and this enables the outflow water quality to be improved largely; furthermore, the removing effect can be improved further by combination use of chlorine dioxide and coagulant.

y� Biological method is selected for deodorization process. By this method, contaminations including low concentration hydrogen disulfide, ammonia, and VOCS etc. can be removed effectively; the deodorization effects are well without secondary pollution, and the operating cost is very low.

y� Direct condensation and dewatering treatment is adopted for sludge treatment process. For direct condensation and dewatering treatment, no digestion tank need be built, and this can save a large number of capital construction investment and routine maintenance cost. Those forming machineries with high performances and simper operating method shall be selected for condensation and dewatering, so that floor area and unpleasant odor can be reduced. Before condensation and dewatering, polyacrylamide shall be added, so as to be easy for sludge condensation and dewatering.

3.2.3 Wuliangsuhai Lake Area Treatment Sub-project 3.2.3.1 Features The steps and contents of Wuliangsuhai Lake Area Comprehensive Treatment Sub-projects are as follows: Determination of treatment scope comprehensive treatment (excavation of grid water channel, and construction of biological transition zone artificial wetland) restoration of favorable ecological environment The purposes of Wuliangsuhai Lake Area Comprehensive Treatment Sub-projects are to reduce surface source pollution load, restore ecological functions of the lake area, slow down the biological leveling up speed, and improve water circulation in the lake area. For this project, there are totally 2 Wuliangsuhai Lake area comprehensive treatment sub-projects, i.e., Wuliangsuhai Lake Area Pastoral Grid Water Channel Sub-project, and Wuliangsuhai Lake Biological Transition Zone Artificial Wetland Sub-project. (1) Wuliangsuhai Lake Area Pastoral Grid Water Channel Sub-project (2) Wuliangsuhai Lake Biological Transition Zone Artificial Wetland Sub-project 3.2.3.2 Grid water channel excavation in the lake area 1) Arrangement of construction activities y� Construction time

The non-irrigation period of Wuliangsuhai Lake is from December to the next April. The thickness of ice layer in Wuliangsuhai Lake is 70-80cm; construction can be carried out in shallow area during the congelation period, e.g., more shallow than 80cm. For those deep areas, in consideration of excavation and the bearing capacity of transportation, construction shall be carried out after the lake surface is iced out, i.e. from Nov. to the next Apr., and under such weather conditions that the wind class is less than 6 and fog class is less than 2.

y� Excavation work load The sediments in the upper layer (as per a thickness of 40cm) are about 1,180,000m3, and the undisturbed soil in the lower layer is about 2,170,000m3, totally 3,350,000m3.

y� dredging equipment

Figure 3.2-3 Density distribution of reed and float grass Float grass at the bottom of Wuliangsuhai Lake is flourishing; especially the tough reed root system and developing float grass rootstalk will wind the cutter head and disturb the work, so that the work efficiency is reduced, Density distribution of reed and float grass show in Figure 3.2-3. according to the test results of dredging in Suzhou River of Shanghai, if there is garbage or float grass, it is very easy for cutter-suction dredger to be blocked up, and this usually causes shutdown and lower production efficiency. Therefore, in combination with the dredging effects and environment impact, for the area where reed and other float grass are flourishing, it is recommended that 0.8-1.2 m3 type hydraulic

backhoe dredger be adopted, whereas for the sediments in the upper layer where there are less float grass, grab dredger shall be adopted. See Table 3.2-29 for the main specifications and parameters.

2) Technical proposals (1) Grid water channel excavation work and transportation process � The process flow of water channel excavation is as follows:

Dredging shipment water carriage loading/unloading at the pier land carriage substrate sludge dumping

�The excavation sequence shall be:

Zone 1 and Zone 2 can be excavated simultaneously, and Zone 3 and 4 can be excavated simultaneously. As a whole, the excavation shall be from upper reaches to lower reaches, and can be commenced simultaneously in the whole lake area if the construction period is short.

�Water channel plane positioning:

GPS positioning stake and guy rope shall be adopted for marking out the trend of outflow course. Longitudinal sign shall be arranged in the central line of dredged channel and designed upper opening boundary, and transverse sign shall be arranged at the construction boundary of the starting and stopping point of the dredged channel and in the straight reaches of curve bend.

�Trend of the excavation line:

As shown in Figure 3.2-4, the whole lake area is divided into 4 zones, each of which is with a corresponding substrate sludge dumping site. The dredger shall commence the excavation along the water channel trend. The overall sequence of water channel excavation shall be from the upper reaches to the lower reaches.

�Dredging:

The dredger shall begin to work with support of tugboat. The bow shall be arranged in the direction of the lower reaches; a traverse anchor shall be provided on both sides and a stern retracting anchor is provided respectively, and totally 4 anchors to fix or move the ship position; cable length is less than 50m. Before trial excavation, measure the water depth at the bottom, and control the down letting depth of backhoe on the basis of the water level. The sediments in the upper layer, which is about 40cm, and substrate sludge in the lower layer shall be excavated respectively, and they shall be transported and stored separately. During operation, firstly insert 3 work piles into water and hold them down to the water bottom till the blow tilts to a height, so as to fix the hull; and then, start up the lifting, bulldozing, and turning devices of dipper machine to carry out shoveling and excavation jointly. The work pile at the end shall also be used for supporting the recoil caused by shoveling and excavation and controlling the direction to move forward the ship position. For the shoveled substrate sludge, use turning device to turn the dipper to be overhead the sludge barge, and use the dipper starting mechanism to open the rod bolt and buffer spring, so that the dipper bottom can be open under deadweight and the load, so as to discharge the sludge.

For the area with shallow water (e.g. less shallow than 80cm), construction may be carried out in winter, so that excavator can be operating directly on the ice surface, and transporter can be directly driven on the ice surface.

�Shipment:

The dredged sludge shall be transferred and loaded onto the barge berthed beside. After a fleet (5 barges) is loaded orderly, use tugboat to drag to the dumping site.

�Transportation method:

Use sludge barge and sludge carrier jointly to transport the substrate sludge. Use backhoe dredger to load the dredged substrate sludge directly into sludge barge berthed beside the dredger; and then, use sludge barge to transport the sediments from the upper layer and undisturbed soil form the lower layer separately. For this, the sediments from the upper layer shall be loaded into 5 barges and be dragged by a tugboat to the temporary pier nearby, and the barge can be berthed for discharge before the sludge is transferred to transporter and then be transported to the dumping site nearby; the undisturbed soil from the lower layer shall also be loaded into 5 barges but be dragged by a tugboat to the artificial island area as planned in the center of the lake. Finally, the tugboat shall drag the empty barge from the site back to the dredging working area and wait for loading again. In winter, the transporter can directly be driven on the ice surface, so the transportation shall be easier.

�Dumping and stacking:

Use the grab bucket of fixed type tower crane to grab and excavate the substrate sludge from the barge and unload to the dump truck in temporary pier, and then, transports the substrate sludge to the dumping site to fill the wide trench, without further special anhydration treatment.

Figure 3.2-4 Layout of water channel excavation and substrate sludge stacking

(2) Substrate sludge dumping site

The substrate sludge in the upper layer of the lake bottom is mainly sediments, and the area is about 1,180,000m3. After excavation, the substrate sludge from this part shall be transported to 4 dumping sites for stacking treatment. The substrate sludge in the lower layer is mainly unpolluted soil, and the area is about 2,170,000m3. It shall mainly be used for stacking of artificial island in the lake area and shall not be transported outwards. According to the tourism plan on Wuliangsuhai Lake, many artificial islands will be built up in the lake area. see Figure 3.2-4 for the details of artificial islands. � Location of substrate sludge dumping site According to the space around Wuliangsuhai Lake area, earthwork of water channel in the lake area and the space distribution, 4 substrate sludge dumping sites shall be arranged. See Figure 3.2-4 and Table 3.2-19 for the details.

Figure 3.2-7 Section of the pier structure 3.2.3.3 Pilot project of agricultural non-point source pollution treatment 1) Significance of demonstration for non-point source pollution control

For treatment of aquatic environment in Bayannaoer City, many kinds of pollution shall be revolved, but mainly includes point source and non-point source pollution. Along with the gradual control over industrial and city point source pollution, non-point source pollution will become a confinement factor for improvement of aquatic environment of the irrigation area in the upper reaches of Wuliangsuhai Lake. Therefore, according to the basic agricultural production state of Hetao Irrigation Area in Bayannaoer City, and on the basis of Control over Farmland Subsiding Water Pollution in Irrigation Area in the Upper Reaches of Huanghe River and Research and Demonstration of Key Technologies for Wetland Restoration, which has been started for special national water project, in this project, local control and treatment for subsiding water pollution are expanded, and a combined treatment concept of “reducing the number of sources, controlling the process, and treating the terminals” is embodied. In the special demonstration plot in Hetao Irrigation Area in Bayannaoer City, the demonstration of nitrogen and phosphorus control shall be extended, so as to provide an action plan for further control over the subsiding water pollution in the irrigation area. 2) Location of demonstration plot Inner Mongolia Drainage Field 9 Beichang Branch Ditch Demonstration Plot is located in Beichang Community of Xiangqinghua Village of Beigedu Township in Wulate Qianqi, Inner Mongolia, and Tabu Community of Dengcundian Village. It is in the northwest of Wulate Qianqi, and 30km away from Wulate Qianqi (108°33 47 E, 40°45 29 N). To the demonstration plot, the east is National Highway 110, the south is Tabu Trunk Canal of Hetao Irrigation Area, and the west is Branch Canal 4 and the north is Beigedu Township highway in Wulate Qianqi (Figure 3.2-6).

Figure 3.2-6 Demonstration plot of Beichang Branch Ditch in Drainage Field 9 of Hetao Irrigation Area in Inner Mongolia 3) Backgrounds For Inner Mongolia Drainage Field 9 Beichang Branch Ditch Demonstration Plot, water is mainly diverted from Huanghe River for gravity irrigation; the farmland and ditch and road are planned normatively, and the landform is flat. Irrigation canal system mainly is comprised of Tabu Trunk Canal and Branch Canal 4; farmland subsiding water is mainly from open drainage, lateral seepage, and seepage, and then is drained into Beichang Branch Ditch and finally into the Trunk Canal 9. For the demonstration plot, there are 10 villager groups of Beichang Community in Beigedu Township and 6 villager groups of Tabu Community in Dengcundian Village involved, the cultivated area is about 4500Mu, 1100 farmer households, and the population is 3620. In recent years, sunflower, corn, wheat, and oil sunflower are mainly planted in the Demonstration Plot. Calculated as per straight gash canal, the annual water consumption has been 2,000,000-2,500,000m3. According to the soil fertileness, the farmland has been provided with medium-high yield. The average yield of sunflower per Mu is 150kg, corn is 400kg, and wheat is 300kg. Pesticide and chemical fertilizer has been adopted at a high level, for which, the sunflower per Mu is RMB120 Yuan, corn is RMB100 Yuan, oil sunflower is RMB100 Yuan, and wheat is RMB360 Yuan. This demonstration plot is very representative in the irrigation area in Inner Mongolia. For the demonstration plot, the supporting facilities for irrigation and drainage are provided at a high level, and investment in agricultural chemical fertilizer and production level are also high; supporting facilities

for channels at lower levels are provided well, and the gradient ratio of channel is 1/6000. Therefore, the demonstration plot shall be an ideal site for research of the features of farmland subsiding water pollution. 4) Contents of non-point source control demonstration and promotion Control over agricultural source pollution in the irrigation area is a non-point source control system project, which shall be carried out by stages and be promoted from experiment unit to the whole irrigation area. For the demonstration, the key contents include demonstration and promotion of key technologies for nitrogen and phosphorus control for the main crops on the basis of reduction of nitrogen and phosphorus pollution in farmland subsiding water, and that of the integrating technologies for wetland restoration polluted by farmland subsiding water in the irrigation area. The promotion of controlling technologies for non-point source pollution in the demonstration plot shall be combined in the appropriation budget of World Bank project, and the main contents are as follows: (1) Demonstration of promotion of water saving technologies to reduce running off of nitrogen and phosphorus On the basis of the irrigation management technology optimizing water saving in the demonstration plot, utilize laser grader to level up and divide the farmland into blocks to optimize water saving technology, so as to reduce farmland subsiding water amount and reduce funning off of nitrogen and phosphorus contamination and farmland subsiding water pollution. The area is 4500Mu. (2) Demonstration of fertilization technology For the representative crops in the demonstration plot, under soil determination and fertilizing technologies, utilize advanced fertilizing machines for accurate fertilization and demonstration, so as to reduce the amount of applied fertilizer, improve utilization ratio of chemical fertilizer, and reduce farmland subsiding water pollution caused by running off of nitrogen and phosphorus. The area of accurate fertilization and demonstration by fertilizing machines is 1000Mu, and that artificial fertilization and demonstration for nitrogen and phosphorus control is 200Mu. (3) Economic considerations for farmers The farmers participating in the non-point source pollution in the irrigation area must change the former cultivation, fertilization, irrigation habits but put in more energy, labors, and financial power, so it is necessary for an amount of economic grant to be provided for the farmers. During execution of the project, random investigation should be carried out for the farmers, who are totally 150 households, and questionnaires of fertilization and feedback sheets of compounded fertilizing farmland plot management and record shall be prepared, which are totally 1200 sheets; additionally, sign board shall also be made to provide for the investigated farmer household. Furthermore, sample 50 households of farmers for evaluation of irrigation water consumption, fertilization, and effects of subsiding water reinjection and crop growing etc. (4) Field investigation and testing Provide field investigation for the demonstration plot, divide sampling units; investigate the basic properties of the sampled plots, production of foregoing crops, and fertilization state etc., and the surface water environment conditions in the demonstration plot; investigate and sample the background value of farmland subsiding water pollution state, and monitor, compare and test the effects data after demonstration. (5) Propaganda and promotion On the basis of doing well technical training, deploy fertilizer supply systematically, distribute the proposal card for fertilizing and subsiding water reinjection, and provide fertilization direction for the farmers, so as to change any unreasonable habit, such as blindly fertilizing, excessive fertilization, or preference for nitrogenous fertilizer, and improve the scientific fertilizing level. According to the farmer fertilization questionnaires, analysis result of soil, and fertilizer demand of crops, develop more than 40000 proposal cards for soil determination and compound fertilization, which shall be distributed by the agricultural technicians and village committees, and be signed by the householders for confirmation after receiving. (6) Technical training

Firstly do well the technical training for the technicians. By improving the technical level of the technician team, enhance further the training for the peasants and related technicians. Secondly, by means of broadcasting, TV, newspapers and periodicals, technical information, teaching courses, and on-the-spot meeting, enhance propaganda and training work, and direct the peasants to execute subsiding water technologies, so as to improve the farmers’ consciousness of fertilization and water saving, and popularize scientific fertilization technologies and knowledge. It is planned that there will be 75 training courses, more than 330 peasants and 40 technicians will be trained, and 750 banners will be prepared and hung up. (7) Construction of software and hardware for database On the basis of field investigation, farmers’ fertilization state, field experiment, and analysis and test data, collect and work up the field experiment of fertilizer and soil monitoring data on the whole irrigation area in each year, by means of computer technologies, GIS, and GPS, establish databases at all levels for physical and chemical properties of soil, fertilizer efficiency, routine fertilization, irrigation water consumption, and subsiding water reinjection in different areas. 3.2.3.4 Wuliangsuhai Lake biological transition zone artificial wetland 1) Arrangement of construction activities � Quantity of Works

2) Engineering proposal (1) Process flow See Figure 3.2-7 for process flow of biological transition zone artificial wetland Being lifted from the original lift pumping station, the wastewater from Main Trunk Canal will be sent into the time delay wetland system. The water canal from the afterbay of Main Trunk Canal to the large lake can be used as sedimentation canal and be cleaned up every 7 years, and aeration facilities shall be provided simultaneously. At the juncture between the water canal and the large lake, 2 sets of rubber dams shall be provided, one of which is used for controlling the wastewater entering into the artificial wetland, and the other for temporary water release. After flowing into the wetland, the wastewater flows through the crossed zone of reed zone and pond system (zone without reed and that excavated deeply); if necessary, aeration and oxygen increasing measures may be taken (mainly for improving removal ratio of contamination in congelation period of winter), so as to improve purification effects of wetland. After flowing through the circuitous wetland passage, the wastewater flows into the large lake from the juncture between the small lake and large lake through 3 rubber dams, which bear 20%, 20%, and 60% of the outflow respectively. At the outlet, a set of 30m3/s drainage pumping station shall be built up to reduce the wetland water level and drain wetland wastewater, so that reed yield can be improved on the one hand, and on the other hand, after the wastewater is drained, it will be advantageous for oxidization of the substrate sediments, so as to improve the purification effects of wetland and reduce pollution release from the substrate sludge. The outflow rubber dam, pump location, and water distribution shall be determined by analog computation, and this will be more favorable for optimization of flow field.

4. Environmental Baseline 4.1 Profile of Regional Environment 4.1.1 Environmental Profile of Bayannaoer City 4.1.1.1 Natural Environment 1) Geographic Location Bayannaoer is located in north China’s frontier in west of Inner Mongolia Autonomous Region between 40°13 -42°28 N and 105°12 -109°53 E. It is bounded on the east by Baotou City and Ulanqab League, on the west by Alashan League and on the north by Mongolia and faces Ikchor League across Yellow River to the south. About 378km long from east to west and about 238km wide from north to south, it covers an area of 65,551km2, accounting for 5.46% of the total area. 2) Geological Structure Bayannaoer geological position steps astride two primary geotectonic elements, namely, Tianshan Mountain-Inner Mongolia-Hinggan Palaeozoic geosynclinal fold region to the north and Sino-Korean paraplatform to the south, which are bordered by Badain Jaran- Wulatehouqi County-Kangbao- Chifeng- Changtu Major Fracture (close to about 42°N). According to different internal structural features, it can be further divided into four secondary and five tertiary tectonic elements. In the long geological age, these tectonic elements underwent different evolvement, showing distinct and different structural features. The complicated geotecture and active tectonic movement here exert a control action on age base, sedimentary formation, magmation and even formation of minerals in this area. 3) Landform The landform in the whole city clearly falls into three categories: high plains in the north, hills in the middle and plains in the south. y� Urad Plateau

Located in the north part of the city from hills at the foot of north Yinshan Mountain to the south to the national boundary to the north and covering an area of 30,600km2 with an elevation of 1,000-14,00m, it is a part of Inner Mongolian Plateau. It is mainly composed of tertiary river-lake red sandstone and sandy mudstone and quaternary glutenite. Due to strong dry denudation, stony monadnock and deflation hollow are formed. Owing to the lack of rain, wide and shallow riverbed has flows only in wet season to converge at the northern depression to form an interior drainage. To the north of the depression, in the region of frontier of China and Mongolia are sprinkled with dryly denuded monadnocks joining intermittently.

y� Hilly Area of Yinshan Mountains Located in the south of Urad Plateau, it lies in the middle and southeast parts of Bayannaoer from east to west. In terms of the distribution position, it can be divided into three parts: Longshan Mountain, Serteng Mountain and Ural Mountain.

y� Hetao Plain Located in the south part of the city, it can be divided into four parts in terms of landform: Wulanbuhe Desert, Houtao Plain, Ming’an River and Sanhuhe Plain.

Wulanbuhe Desert: spreading out in the southwest of the city, between Langshan Mountain and Baotou-Lanzhou Railway, including most Dengkou County and southwest Hangjinhouqi County, it covers an area of 3,400km2. With an elevation between 1050m and 1030m, it gradually drops down from southeast to northwest, gradient ratio being 1/5000.

It forms a strip of depression belt between the alluvial plain high in the south and low in the north and the proluvial plain high in the north and low in the south, which now is the location of the general arterial drainage of Ugab River and the marsh. Yellow River alluvial plain is the principal part of Houtao Plain, taking up about 3/4 of the plain’s total area. Bordered by Ugab River, it is 40-50km wide from north to south. With flat terrain, the elevation is usually 1,020-1,040m. High in the west and low in the east, the gradient is 1/3,000-1/5,000; High in the south and low in the north, the gradient is 1/4,000-1/8,000; only local part shows gentle rolling.

Ming’an River is located in the intermountain basin to the south of Baiyunchahan Mountain and to the north of Ural Mountain. From the Wuliangsuhai lake to the west to the 1200m contour to the east of Tailiang, it is about 50km long from east to west, taking an area of 1,800km2. The middle part of the basin is fluvial plain, and the north and south parts are fluvial-alluvial plain and piedmont proluvial inclined plain.

Sanhuhe Plain is located between Ural Mountain and Yellow River. From Xishanzui to the west to the boundary of Bayannaoer and Baotou, it is a narrow strip, about 70km long from east to west and 3-15km wide from north to south, taking an area of 700km2.

4) Hydrogeology Ground water mainly comes from precipitation infiltration and little condensation recharge, its distribution regularities mainly having close relation with such factors as geological structure, lithology, terrain and weather. The distribution of ground water in the city features with gradual decrease from east to west and from south to north. In terms of distributed burial and water conservation feature, ground water is divided into perched water, phreatic water and confined water (artesian water). In terms of the rock feature of water carrier, ground water in the city can be divided into bedrock fissure water, plateau red earth pore water, quaternary loose rock pore water, quaternary desert aeolian sand pore water, Hetao Plain aeolian quaternary alluvial-proluvial lacustrine formation pore phreatic water and confined water. 5) Climate Bayannaoer, far away from ocean, dwells on plateau in inland. The climatic characteristics: four distinct seasons, less snow in cold winter, much wind in dry spring, little rain in heated summary and mild and cool autumn. It is typically continental monsoon climate in medium temperate zone.The annual average temperature in Bayannaoer is 3.7-7.6�. The temperature decreases progressively from southwest to northeast The average annual precipitation of the city is 188mm, and 177-285mm in the east and 99-184mm in the west. Markedly affected by monsoon, the city has its wind direction varied greatly with season in a year. Under control of Mongolia cyclone during October to the next March, the city is dominated by north wind or northwest wind. The average annual relative humidity is 42-54%, where that in Hetao area is 47-54%, and 42-48% to the north of Yinshan Mountain. The average annual evaporation is 2,032-3,179mm. the average annual hours of sunshine is 3,215.1-3,401.8hrs, and in Hetao area, 3,184.6-3,221.0hrs. The number of sunny day in the city in a year is 109-31, and cloudy day, 42-63. 6� River and Hydrological Features There are many rivers in Bayannaoer and are divided into two drainage systems by the divide of Yinshan Mountain: Yellow River system to the south and inland river system. (1)Rivers Yellow River system: originated from the north foot of Bayan Har Mountains, Qinghai Province, Yellow River flows through Gansu and Ningxia to the city. Tributaries converging at north bank of Yellow River are gully rivers from Langshan Mountain and Ural Mountain. There are a total of 147 gullies, large or small, in Langshan Mountain, with a catchment area of 13,000 km2. Gullies in Ural Mountain totals 28, with a catchment area of 388 km2,. Inland river system: the inland river system in the city spread out over the pateau to the north of Yinshan Mountain. Its drainage area is 31,000 km2, including 34 inland rivers, of which, most are seasonal stream. Lakes: there are 318 lakes taking an area of more than 2ha, with water area of 3,141,555mu. These lakes are scattered over Hetao Plain. Wuliangsuhai Lake, water surface of 44,985mu, the average depth 0.7m, and the storage capacity 209,930,000 m3, is the largest lake in the city, and is the drainage and mountain torrent receiver of Yellow River irrigation region in Hetao Plain as well. (2)Hydological Features of Rivers

Except Yellow River, the hydrological features of Bayannaoer’s rivers depend on local conditions of precipitation, evaporation and geological geomorphology. � Yellow River

Flowing from Ningxia to Bayannaoer, Yellow River’s average annual transit water quantity is 31,500,000,000m3. In terms of cause of formation, floods occurred in Yellow River are mainly divided into ice flood and storm flood. Ice flood is a result of melting ice in riverway and release of stored water in river channel. It often occurs in March, also is called ice flood. Storm foold often occurs from July to September. The flood may happen twice to three times a year, and even 5 times in few years. The average volume of flood is 3,000-4,000 m3/s. The sediment concentration in the stretch in Bayannaoer is about 6kg/m3.

� Other Rivers within the City

Brooks in the city are mountain stream, usually with extremely less volume of fresh water. Summer rainstorms result in outbreak of flash flood. With incoming water and flood under control of rainstorm, the brooks experience steep rise and drop in short time. The annual average runoff in the city is 331,000,000m3, where Yellow River system takes up 237,000,000 m3, the inland river system accounts for 94000,000 m3.

Hetao irrigation area involves to all counties in the Bayannaoer, including 108 towns, farms and stations with a total area of 11195.4km2,the irrigation area is 5743.6km2.The drainage system in the Hetao irrigation area includes 7 levels, there are one general drainage ditch ,12 drainage ditches, 60 drainage sub-ditches, 225 branch ditches and about 22000 small ditches, the general drainage ditch is the main project of drainage system, the total length is 257.283km, the drainage area under control is 7583.7 km2,the mountain torrent area under control is 13313 km2 ,the drainage volume accounts for 93% of the total drainage volume in the irrigation area ,the remaining is directly drained into Yellow River through other drainage ditches. The water is flowed into the Ulansuhai at the end of truck, Ulansuhai is main part of irrigation works in Hetao area, it is the only acceptance water body and drainage channel for withdrawal of agriculture irrigation water in the Hetao area, it has accepted more than 90% drainage water in the irrigation area, the drainage water from the Bapaigan and Jiupaigan are directly run into the Ulansuhai ,which account for 14% of the drainage capacity of the general drainage ditch; the total length of export section is 24 km, the drainage area under control is 232.67km2,which account for 3% of the drainage area, the water is excluded into the Yellow River through the export section of general drainage ditch. Shipaigan is directly excluded into the export section, which account for 2% of the drainage capacity of the general drainage ditch. 7�Natural Resources (1) Land Resources The total land area of the city is 65,551.5 km2 (98,327,000 mou), which can be classified into seven main categories, including cultivated land, garden plot, wood land, grass land, non-agricultural land, water area and hard-to-use land. The cultivated area of the city is 7,170,362 mou, totaling 7.3% of the gross land area, about 5.1 mou per capita, which is mainly distributed in Hetao Plain and Northeast Hilly Country. The fruit garden (inclusive of sprinkling garden fruit trees) is 26,471 mou, taking up 0.027% of gross land area, which is mainly distributed in Linhe City, Northwest of Hangjinhouqi County, Bayantela and Chengguan Villages of West Wuyuan County, and Siba, Baleng and Gongdi Villages of Dengkou County. The available forest land area is 1,338,554 mou, occupying 1.36% of gross land area. And the grassland area is 54,622,000 mou, taking up 55.55% of gross land area. The land for urban residents and industrial and mining purposes is 1,059,000 mou, occupying 1.078% of gross land area. The water area is 3,141,500 mou, taking up 3.2%. The hard-to-use land is 30,212,500 mou, occupying 30.73%, which mainly includes 2,799,200 mou saline land, 3,973,500 mou flowing aeolian sandy soil, 23,243,200 mou bare rock and gravel, 1,535 mou marsh and 193,100 mou bare soil.

(2) Water Resources The water resources of city are made up of surface, underground and cross-border water. The surface water is from Continental River and Yellow River. The drainage area of Yellow River water system is 34,000 km2, taking up 52% of total city area. The normal runoff is 237 million m3, occupying 71.6% of that of the whole city. The endothermic river is 31,000 km2, taking up 48% of the whole city. And its normal runoff is 94 million m3, taking up 28.4% of the whole city. The underground water comprehensive recharge capacity of the whole city is 3.21 billion m3 with 1.81 billion m3 workable reserves. The underground water is distributed from east to west and south to north. Along the lower course of Hetao Plain and south of Ugab River, the underground water mineralization degree is more than 3g/l with some area even above 10g/l. Therefore, the water is bad in quality and less in quantity. The hydration type of water is Cl—SO4. The cross-border water is mainly from Yellow River with a normal runoff of 31.50 billion m3. The interannual and inter-monthly change of annual runoff of Yellow River is great with maximum 50.50 billion m3 and minimum 18.30 billion m3. Since the establishment of China, Bayannaoer has constructed a lot of projects to make good use of water resources, including 1 Yellow River Sanshenggong Key Project, one 228.9 km general main cannel, 9 sectional projects, 13 main canals totaling 790.1 km, 43 sub-canals totaling 958.30 km and 249 branch canal totaling 1,750 km. Even the piping engineering under Dounong Canal has been provided with some supporting facilities becoming the largest irrigation area controlling canal in China. The existing irrigation area is 6 million mou, which is the foundation for Bayannaoer to develop agriculture. The drainage system has one main arterial drainage totaling 206 km, 13 main stream gullies totaling 508.5 km, 62 sub-main stream gullies totaling 1,032.3 km and 139 branch gullies totaling 206 km. Therefore, the drainage major projects have taken shape. For the sustainable and stable development of agricultural production in Hetao Irrigation Area, the water diversion irrigation from Yellow River is a major condition. 4.1.1.2 Social Environment 1) Administrative Division At present, Bayannaoer administrative division has 4 banners (Urad Front, Middle and Back and Hangjin Back), 2 counties (Wuyuan and Dengkou) and 1 district (Linhe), covering 106 villages and towns and offices, among which there are 19 sumu (villages), 32 villages, 45 towns (all 96) and 10 offices. The banners, counties and cities administer 18 towns, 82 villages, 23 sumu (villages), 795 villagers’ committees, 141 administrative villages, forming a town layout of one village in 30 Li (half of km) and one town in 50 Li. 2) Urban Population The fertility rate, death rate and natural growth rate of Bayannaoer City are 5.68‰, 2.99‰ and 2.68‰. By the end of year, the gross population of domicile has reached 1,761,300, an increase of 1.15% over the previous year. According to the statistics of family planning departments, the average annual natural population growth is 5,000-6,000 persons with a low mechanical growth rate. According to the statistics of municipal public security bureau, the population growth rate, inclusive of floating population, in central city of Bayannaoer has exceeded 10,000/year. 3) Socioeconomic Development The total output value of Bayannaoer area in 2005 was 21.70 billion Yuan, an increase of 1.1 over 2000 on comparable basis. The agricultural production continued to be rich harvest in successive years and service industry continued to expand in scale and gross amount at the time of industrial optimization and updating. The industrial output doubled in two years and increased by two times in three years becoming an active force to bring along the economic growth. The municipal financial revenue in 2005 reached 2.123 billion Yuan, an increase of 2 times over 2000. Now, the municipal economy has taken on a great-leap-forward development and stepped into a new phase of per capital GDP from USD 1,000 to 3,000. The industrial structure experienced profound changes making the structure of three industries change from 39:26:35 to 30.6:38.5:30.9, among which the primary industry went down 8.4% and secondary industry up 12.5%. The urbanization proportion was improved to 41% from 36.9%.

The per capita disposable income of urban residents reached 8,022 Yuan and per capita net income of farmers and herdsmen was 4,265 Yuan in 2005, an increase of 67� and 76.4� over 2000 respectively. The outstanding of deposits from urban and rural residents increased by 100% over 2000. The poverty-stricken population in agricultural and pastoral areas went down to 150,200 in 2005 toward 259,200 in 2000. Housing, education and tourism became new consumption points. More than 60,000 people entered the labor force. The payout ratio of pension was 100%. The registered unemployment rate of urban residents was controlled at 4.25%. And urban minimum living standard was completely and well implemented. 4.1.2 Environmental Profile of Subitem Location 4.1.2.1 Wulateqianqi County 1) Natural Environment (1) Geographic Location Wulateqianqi County is located at the southeast of Bayannaoer City, Inner Mongolia Autonomous Region, whose geographical coordinates is E108° 12 -109° 54 and N40° 26 -41° 16 and east side is next to Baotou City, south next to Dalate Banner and Hangjin Banner of Erdos City across Yellow River, west close to Wuyuan County and North bordered on Wulatezhongqi County. The banner location, Ural Mountain Town, is 288km from Hohhot City and 142km from the Bayannaoer Municipality. (2) Landform and Physiognomy The project area is a part of Hetao Plain located between Ural Mountain (west section of Yinshan Mountains) and Yellow River. Influenced by regional structure, the area extends in east-west. The plain terrain topography slopes from northwest to southeast, yet, is even and wide with slightly fluctuation at local parts. The topography in front of mountains is a dip plain high in north and low in south, which is formed by the Ural Mountain Front Flood Plain and Yellow River Alluvial Plain. (3) Geology Wulateqianqi County is complex in geological structure with fold, fracture and great block mountain developed by deep fracture. The basement rock is made up of Sangkan and Wutai groups of Archean Group and Zhaertai group of Proterozoic Group. Yanshan movement developed front deep fracture from original one. Because of the existence of deep fracture, three stair block mountains, Chashitai, Bayinchagan and Ural, from north to south were formed along with Ming’an, Large and Small Shetai Rivers and different table-top piedmont benchlands. Along the north side of Yellow River Irrigation Area, there is a deep fracture zone extending to Ural River and the new fracture cutting in front of Ural Mountain, which has enlarged and deepened Hetao fault depression. The north part rise relatively forming high mountains leaving the south part for Hetao Plain. The Ural Mountain Fault Depression is under the latency of Ural Mountain umbos from Xishan Mouth to Sanshenggong along railway. The geotectogene of Wuliangsuhai lake and Sanhu River trough valley formed inland close-type fault basin. From Tertiary to early Quaternary period, the original fracture was further developed into stair-type fracture and undergone the sedimentation of thick and alluviation lacustrine, and alluviation diluvium. The middle and lower Pleistocene Epoch is of successive gyttja and Epipleistocene is of recession of lake water. Yellow River began to develop and experienced gyttja and fluvial facies sedimentation. Later, the diluvial of Yellow River and Front Mountain alluviation formed Hetao Plain. Under the action of human productive activities and Yellow River water, the surface layer was coated with irrigation-warping horizon alluvium. The enclosed geological structure of long-term lacustrine action of Hetao Basin accumulated a very high saline matter in stratum. This gyttja geographical environment has been preventing the smooth running of groundwater runoff leaving an enriched water and soil salt and putting a great influence on the formation of saline soil. (4) River Water System � Surface Water

The main surface waters in Wulateqianqi County are Wuliangsuhai lake, Yellow River and waste cannels and ephemeral streams connecting Wuliangsuhai lake and Yellow River.

Wuliangsuhai lake: Wuliangsuhai lake is located at the east end of Hetao Irrigation Area and north of Xishan Mouth Town of Wulateqianqi County, which is south-narrow and north-wide and

submarine-declining from north to south. It has a total area of 29,333×104m2 occupying 6l.35% of Wulateqianqi County Water Area, which is the largest fresh water lake in west Inner Mongolia. It is celebrated for fish and reed and the raw material site of Wulateqianqi County paper making enterprises. As a part of drainage works in Hetao Irrigation Area, Wuliangsuhai lake mainly takes up agricultural drainage, flash flood water and upstream industrial water drainage, which are led into Yellow River through waste cannel. Waste Cannel: The waste cannel is a main hydro junction to link Wuliangsuhai lake and Yellow River. The mean annual flow is 6.34m3/s, average flow velocity 0.37m/s and average depth 1.4lm.

Remark: The annual mean depletion rate of Yellow River in 24 years is 179 million m3 and average flow is 5.66m3/s.

Yellow River: The Yellow River runs across the south of Wulateqianqi County from west to east leaving a full length of 160km within Wulateqianqi County territory. According to the data from Sanhu River Mouth Yellow River hydrologic station, the annual mean water flow of Yellow River is 830.9m3/s; average flow velocity is 1.34m/s and average sediment concentration 5.26kg/m3.

Ephemeral Stream: The region of interest has 18 ephemeral streams with low water season flow about 46�115m3/h for the larger Wulanbulagean ditch and 25 m3/h for Huhebulagean ditch.

In wet season, the region has flood from Ural Mountain, among which there are 9 main floods with a normal runoff over 400,000 m3 and other 9 small ones with a normal runoff less than 300,000 m3. The flood after running into Yellow River alluvial plain part affluxes into Sanhu River main cannel and part stays in the flood retarding basin formed by front proluvial fan and Yellow River alluvial plain and finally are consumed, infiltrated and evaporated.

(5) Hydrogeology

The region of interest is located at the east zone of Hetao Plain with the north for Ural Mountain Front Flood Plain and south for Yellow River alluvial plain. The Epipleistocene-Holocene Series water-bearing formation of region of interest (Q3 and Q4 water-bearing formation, No. 1 water-bearing formation for short) is well developed and abroad distributed with great thickness, rich water content, shallow bury and close relationship with surface water, which is the main water supply water-bearing formation. The underlying Pleistocene Series upper and lower water-bearing formation (Q2 water-bearing formation, No. 2 water-bearing formation for short) is gyttja pile. The Pleistocene Series upper group is mainly silt deposition. The middle Pleistocene Series lower group �Q2

1�aquifer is great in thickness, shallow in bury, fine in aquifer grain and small in water quantity. Therefore, it is of no consequence for total water supply and of exploitation value in some zone. (6) Water Resources Deducting the double counting amount between the surface water and ground water, the multi-year average gross amount of self-produced water resources in the region of interest is 4183.34×104m3/a; under present situation, the utilizable amount of water resources is 5839.2×104m3/a, of which 2898.24×104m3/a is the utilizable amount supplied by the irrigation of the Yellow River; the amount of ground water resources in salt water area is 2610.25×104m3/a, the utilizable amount of the ground water in salt water area is 1957.69×104m3/a.

Wulatezhongqi County is located in the west of Inner Mongolia and the northeast of Bayannaoer City with the geographic coordinate of E107°16 ~109°42 and N41°07 ~42°28 . It marches with Mongolia in north, neighbors Damao Banner of Ulanqab League and Guyang County of Baotou City in east, neighbors Wulateqianqi County, Wuyuan County, Linhe City and Gangjinhouqi County in south, adjacent to Wulatehouqi County in west. The whole banner is 203.8km long from east to west, 148.9km wide from north to south, with a total area of 22,606 square kilometers. (2) Geological Features Wulatezhongqi County has complex geological structure, including two first-level tectonic units, i.e. with the boundary of the south edge of Chuanjing—Sanggendalai Mesozoic depression, its north is Greater Khingan Mountains geosynclinal folded system and its south is North China Platform. Due to the influences of tectonic movements, plus the affects of several large-scale magmatic activities, the geological structure is seriously damaged and some strata has flaws, folds, bends or even upside down and breaking, which result in the generation and occurrence of various mineral deposits with industrial value. This project is located in the Wolf Mountain—Zhasitaishan Mountain Fold Belt with very complex geological structure, strata changes and sedimentary formation, strong topography cutting and large relative height difference. The rock constituents include: carbonaceous slate, limestone, mica-quartz schist, quartzite, sericite schist, phyllite as well as the granite, pegmatite, quartz veins and volcanic-sedimentary rock, etc. immersed in different periods. Wulatezhongqi County consists of 3 basic landforms: southern piedmont plain, central mountains and northern hilly plateau, with significant regional differences and transition changes. This project is located in the piedmont plain area of Wulatezhongqi County. The piedmont plain area, a panhandle of 120km long from east to west and 2~10km wide from south to north, belongs to Hetao Plain.

(4) Hydrological Features Wulatezhongqi County is divided into two water systems with the watershed of the junction of Wolf Mountain hills with Ulanqab plateau. It is the Yellow River water system in the south of the mountain and the continental river water system in the north. Surface water resource is very poor in the banner and the total surface water resources in the whole banner are 258 million m3, including 220 million m3 of water from the Yellow River which is stable and reliable and used for the development of agriculture. The project location belongs to the alluvium and diluvium phreatic water of Hetao Plain, located in the piedmont alluvial-pluvial fan skirt area in the north of Delingshan Town.. The clay courses become thicker and more and the water yield changes from large to small, from more than 1000m3/d to 500-1000m3/d. The water level changes from deep to shallow, from 20-40m to 3-5m; the water quality decreases with the degree of mineralization gradually changing from less than 1 g/L to 1-3 g/L. However, generally speaking, the piedmont alluvial fan aquifer, with coarse particles, large thickness, abundant water quantity, the buried depth of most water levels of 5-20m and good water quality, is a good aquifer for water supply. River in the north of the project has three branch gullies, flowing across Hailiutu Basin from north to south and flowing into Delingshan reservoir in the south, with the drainage area of 1900km2. The upper main gully is intermittent river; there is clear water trickle at the downstream; the river valley becomes narrow in mountain area and becomes wide after flowing into Hailiutu Basin, generally 600~80 m and the widest reaching 2000m.

There are no physical cultural relics and historic sites within this project area after the retrieval on the local chronicles, statistical yearbook etc. and confirmed by the Wulatehouqi county cultural relics control center. 4.1.2.4 Wuyuan County 1� Natural environment �1�Geographic location Wuyuan County is located o n the west of Inner Mongolia Autonomous Region, at the middle of Bayannao’er, on the north bank of the Yellow River and in the middle of Hetao Plain, at the east longitude of 107° 35 20�-108° 37 50� and north latitude of 40° 46 30�-41° 16 45�, next to Wulateqianqi County at the east, bordering Linhe District at the west, across the Yellow River from Hangjin Banner at the south, north of Yinshan Mountain, bordering Wujia River and connecting with Wulatezhongqi County, covering an area of 2493km2 with the total population of 280,000 (2004), governing seven townships: Longxinchang Town, Taerhu Town, Xinzhonggong Town, Tianjitai Town, Shengfeng Town, Bayintaihai Town, Yindingtu Town and state-own Jianfeng Farm. �2�Topography The territory of Wuyaun County belongs to the Yellow River alluvial plain since the Yellow River is running through the region from west to east at the south-southwest. The topography is featured by a slight slope, high southwest and low northeast, with a natural slope at 1/5000�1/7000 from west to east and 1/8000�1/10000 from south to north, and the ground level is 1 019�1 035.3 meters and the highest point above sea level is 1042 meters. The physiognomy can be divided into terrace, erosion accretion topography, the aeolian dune in accretion topography according to the cause of formation or alluvial plain, dunes, lake, high land and low-lying land according to conformation. �3�soil The soil structure in Wuyuan is formed based on the development and variation of the alluvial deposits from the Yellow River, belonging to intrazonal soil, generally through the stages of deposition and erosion, meadow, salinization, paludification and irrigation slaking. According to the result of the second soil census in 1983, the soil can be divided into 5 soil groups of irrigation-silting soil, solonchak, alkali soil, aeolian sandy soil and meadow soil in 8 subgroups, 26 soil genus and 268 soil local types. The bulk density of soil is between 1.32�1.51 with the scope of porosity by 41.6�49.81%, commonly in basicity. The soil nutrients comprise of rich kalium, medium phosphorus and lower OM and total nitrogen, where the equilibrium content of available K is 305.2ppm, exceeding the standard of Class I, the equilibrium content of available P is 11.26ppm, belonging to Class III, the equilibrium content of total nitrogen is 0.0732%, belonging to Class IV, the equilibrium content of OM is 1.109%, belonging to Class IV, according to the grading standards of national soil nutrient contents.

The soil texture and configuration is very complicated in terms of areal distribution, featured by: much sandiness soil covering 40.41% of the total area, over Minzu village, Fengyu village, Bayan village, Haiziyan village and Bashi village in the west or northwest area of the county; much red mud soil covering 40.87% of the total area, over Shengfeng, Hesheng, Chengguan and Meilin villages; the proportion of the mineral soil and loamy soil is much larger, respectively covering 38.5% and 38.2% of the total area, over Jinqi and Jingyanglin villages close to the Yellow River; the loamy soil is of the largest area covering 59.23 of the total area in the eight villages of Nairi, Yongli, Shanhe, Xiangyang, Fuxing, Taohai, Rongfeng, Chengnan in the middle of the county. With severe soil salinization, the salinization area is 249,500 mu, covering69.11% of the total area in the county. �4�Engineering geology As for geotectonic element, Wuyuan belongs to the latitudinal tectonic belt from Yinshan Mountain and Tianshan Mountain, and changes into inland downfaulted basin under the impact of Neocathaysian tectonic system, becoming part of Erdos platform depression, where the base is Archean metamorphic rocks. Depressed at the end of Mesozoic Era, the landform receives continental deposit; during the Himalayan orogeny in the Tertiary period, massive and thick deposits from the Tertiary period piles up since the piedmont depression begins to break and the Hetao Basin rapidly sinks due to heavily swelling of Yinshan Mountain, when the climate is dry and hot, the deposits are oxygenized into red stratum with higher salinity. The entire territory belongs to Hetao Plain, covered with loose stratum of the Quaternary Period, depositing thicker lake facies stratum, where the upper is the alleviation and aeolian deposits with the main lithology of interbedding of fine sand, silt and sand clay, featured by clear sand bedding by 10-70m of thickness; the middle is the alternating layer between lake and river, with the main lithology of interbedding of sludge fine sand and clay; the bottom is the massive and thick lacustrine deposits layer from the Quaternary Period, with the main lithology of sludge and sand clay. The base landform belongs to Yellow River alluvial plain and the engineering geology is basically the same as that at the county seat, where the surface layer is mainly comprised of Yellow River alluvial deposits, with the lithology of fine sand, silt and clay, under which is the lacustrine deposits, with the lithology of sub-clay and clay with gravel layer among them. The base holding capacity: it is 10-14t/m2 for sub-clay with maximum frozen depth of 1.23m and the underground water of 1-2m, from the overall perspective, the base engineering site is very good without obvious unfavorable geology, basically suitable for use of land in construction. �4�Gydrologic condition There are so many deflation hollows formed by Yellow River aluvial deposit under the impact of aeolian erosion for a long time and the natural moats formed by erosion of Yellow River’s change its course, which gradually form into various lakes (locally called Boer Holes) due to water accumulation all year around. There are 171 lakes with the area more than three mu, covering a total area of 54,500 mu, of which there are five lakes with the area more than 1000 mu, covering an total area of 10,600 mu, 37 lakes with the area more than 100 mu, covering a total area of 13,300 mu. There are 116 lakes with the depth mare than 1.5m, covering a total area of 27,100 mu. In 1986, the used lake area was 38,000 mu, accounting for 70%. �5�Hydrogeological condition The underground water distribution is broad and abundant, comprising of phreatic water, shallow confined groundwater and deep confined water. The shallow water and phreatic aquifer from the Quaternary aquifer have an average thickness of 60m with the peak at 120m, where the embedding depth of phreatic water is relatively shallow and the LWL is 2�3m away from the surface with an annual variation of 1�2.7m, deeper in higher land and shallower in low-lying land and irrigated area. The monthly variation of the embedding depth changes greatly due to the leakage of irrigation channels and irrigation water, featured by the underground water level rises during irrigation and decreases when irrigation is stopped. The deep confined water in the settled layer of Lower Pleistocene at the mid-Mesozoic Quaternary is mostly buried under the stable dirt bed, where the semi-confined aquifer (Q+4 aquifer in short) has the most thickness. Under the impact of tectogenesis, the county can be divided into three hydrogeological zones: the latent uplift zone in the south along the Yellow River where the base is latent uplifting and

the buried depth of aquifer plate is 50130m and the thickness is 30100m and the specific capacity

per well is 5 10m2/h; the deep depression zone centered on Yongsheng at Yongli village and Liansheng at Yindingtu village in the middle of the county, where the buried depth of aquifer plate is 130�210m and the thickness is 100�160m and the specific capacity per well is 10�20m2/h; and the shallow depression zone in the north and east areas of the county, where the buried depth of aquifer

plate is 160m and the thickness is 90100m and the specific capacity per well is 5�10m2/h. According to the distribution of phreatic water, the county can be divided into bittern zone, salt water zone, upper-fresh-bottom-salt water zone and fresh water zone. Replenishment runoffs and drainage conditions: the supply of underground water is mainly from irrigation water, annual average of 669.5 million m3/h, and then annual average of 111 million m3/h from infiltration of atmospheric precipitation, and the comprehensive replenishment of annual average of 780.5 million m3/h. the inflow and outflow of groundwater runoff is basically the same, featured by seeping when the Yellow River water level is high and regressing when the level is lower with a less difference. �6�Climate and weather Wuyan County has four distinct seasons with fine weather more than rainy weather and the transmittance of light of the air is very good with abundant light, the intension of solar radiation is very strong with plentiful light energy resources and heavy evaporation capacity; the total annual average sunshine hours are 3230.9 and the percentage of sunshine in an average is 73%. The annual mean temperature is 6.1�; the amplitude of annual extreme air temperature is 73.1�, the annual amplitude is 35.9�; the annual evaporation is 2039.2mm; annual mean frost-free period is 158 days; the average annual thickness of frozen soil layer is 100�120cm, where the plow layer is frozen in late Oct and melted in late April with a frozen period of 180 days; being windy, the annual mean wind velocity of Wuyan is 2.7 m/s. �7�Land resource The total area of various land classifications within the Territory of Wuyuan County is 3,739,300 mu, converting into 2492.9 km2, which can be classified into 39 kinds in 8 classifications according to the classification standards in national Technological Rules of Survey About The Present Situation of Land Use.The arable land is 1,607,600 mu, accounting for 42.99% of the total land area�Garden plot is 1000 mu, accounting for 0.03% of the total land area�Woodland is 128,200 mu, accounting for 3.43% of the total land area�Meadowland is 297,500 mu, accounting for 7.95% of the total land area�Residential, industrial and mining land is 144,600 mu, accounting for 3.87% of the total land area�Lands used for transportation is 24,100 mu, accounting for 0.64% of the total land area�Water area is 350,000 mu, accounting for 9.37% of the total land area�Unused land (including the land hard to use) is 1,186,400 mu, accounting for 31.27% of the total land area. �8�Vegetations The natural vegetations include Cacumen Tamaricis, dryland willow, precarious, reeds, Chinese wildrye, Tribulus terrestris and wormwood. With the expansion of arable and irrigated area, the rising of groundwater level and the aggravation of soil salinization, the vegetation communities have been superseded by artificial vegetations. According to census, there are more than 200 wild plants in 99 species of 15 families in the county with a vegetation coverage rate of 30�50%, where the artificial vegetation is mainly comprised of farm crops and forest plantation�There are six kinds of natural vegetations at present, respectively including: the sand vegetation distributing over aeolian sandy soil and sandlot (such as white Tribulus terrestris, caltrop, Agriophyllum aranarium, Artemisia desertorum and liquorice); the drought-resistance meadow vegetation distributing over relatively highland (such as Peganum harmala, Sophora alopecuroides and celery wormwood); the wetland meadow vegetation distributing over the low-lying places under the high mounds (such as Chinese wildrye, Melilotus officinalis (L. ) Pallas, chickling, reeds, Xanthium sibiricum Patrin, Cirsium segetum Bunge, dandelion, China ixeris, semen plantaginis, Herba Polygoni Avicularis, Johnson evening primrose and sedge); the aquatic meadow vegetation distributing over the flat bogs with perennial or seasonal water (such as reeds, polboschoenus sp, and Typha angustifolia); the salt-resistance vegetation(such as Cacumen Tamaricis, Achnatherum splendens, white Tribulus terrestris, narrow-leaved oleaster, and crawling reeds); the halophytic vegetation distributing over the solonchak (such as Kalidium foliatum, Suaeda and Halimocnemis).

According to the monitoring results tables from 4.2-1 to 4.2-6, and the evaluation results tables from 4.2-7 to 4.2-12 for various sub-projects, the hour mean and daily mean of SO2, NO2 at each sub-project monitoring spot can meet relevant requirements of the standards; except that some of the monitoring spots at Lihuiquan village nearer to the wastewater disposal project and water supply engineering of reclaimed waterwithin the Industrial Zone of Wulateqianqi County, Liuwengedan of the water supply engineering of reclaimed waterof the seventh drainage canal, Reservoir control office of the wastewater disposal project and water supply engineering of reclaimed waterwithin the Industrial Zone of Ganqimaodao, Unity team 3, Dasong village and Shawan village of the water supply engineering of reclaimed waterof the third drainage canal don’t exceed the standards, the daily mean of TSP, PM10 at the sub-project monitoring spots in most areas exceed the standards, of which the over-limit ratio of the treatment project of Wuliangsuhai lake Lake reaches 100%. The evaluation results indicate that the proposed sites of the wastewater disposal project and water supply engineering of reclaimed waterwithin every Industrial Zone suffer from the particle's pollution at a certain extent, especially the Wuliangsuhai lake Lake area has suffered from severe particle's pollution. The particle and PM10 exceed the standards, on the one hand, because the construction area of the project belongs to aria area in the north, dry and windy all through the year, with sparse vegetation and more naked soil surface, on the other hand, the winter of the construction area of the project is cold and long, resulting in longer heating period and more coal consumption, which is the main cause. This monitoring of air environment quality has been conducted in the cols and arid winter, directly resulting in the particles over the sub-project construction area exceeding the standards and especially when the Wuliangsuhai lake Lake area is at the reeds harvesting season, the particles over Wuliangsuhai lake Lake exceed the standards seriously. With the gradual improvement of the regional eco-environment and the implantation of centralized heat supply, the particle pollution in the region will be reduced. The character pollutants such as NH3 and H2S relating to this project can meet the requirement of environmental quality standard and no index is detected. As stated previously, the air environment quality over the construction area of each sub-project is just so so, suffered from the particle pollution at a certain extent; and greater efforts should be made to restore the vegetation around the area of the sub-project plants. 4.2.2 Current surface water environmental quality assessment 4.2.2.1 The water environmental quality assessment in 3rd and 7th Drainage Canal and General Drainage Canal

From the water quality monitoring results in Table 4.2-13�Table 4.2-15 and the water quality evaluation results in Table 4.2-16�Table 4.2-18, which should be known that:

y� From 2004 to 2008, the water in Sanpaigan has been seriously polluted, the major pollution indicators,

COD�BOD�TN�Ammonia-N and TP, were all exceeded, of which, the Standard Rate of COD and TN over the years all were 100%, the maximum Pollution Standard Index of TN and Ammonia-N in 2006, respectively, reached 283.33 and 264.67, and their Standard IndexAnnual average is 115.53 and 108.47 respectively; however, it shows a yearly decreasing trend seeing from the Pollution Standard Index changes over the year, therefore, with the continuously intensifying environmental protection in Bayannaoer City, the water quality in Sanpaigan improved.

y� The water quality in Qipaigan has also been seriously polluted, the major pollution indicators, COD�BOD�TN�Ammonia-N and TP, are far beyond the standard, except for TP, the pollution indicators standard rate of others over the year all were 100%, the pollution Standard Index average value of COD is 14.27-36.39, that of BOD is 21.98-39.79, that of TN is 38.8.27-78.2, and that of Ammonia-N is 13.33-75.07, this shows that�the water quality in Qipaigan has remained a serious state of pollution, as well as threaten the water environment quality security of Wuliangsuhai lake.

y� Although the water quality in General Drainage Canal has been polluted certainly, compared with the water environment quality in Sanpaigan and Qipaigan, it has the relatively light pollution, the major pollution indicators are COD�BOD�TN�Ammonia-N and TP etc., of which, COD and TN are polluted more seriously, their Standard Rate over the yaer are above 50%, the pollution Standard Index average value of COD is 1.99-3.81�and that of TN is 3.55-18.42�while that of BOD and TP are relatively better, the pollution Standard Index average value of them is respectively between 1.09-2.38 and 1.12-2.13; it also shows a yearly decreasing trend seeing from the annual average pollution index over the year, but the water environment quality in General Drainage Canal is gradually improved.

2 Heavy metal monitoring result and evaluation y� Heavy metal monitoring result for surface waters This environmental impact assessment adopts the method that combines historical monitoring data and field sampling monitoring, so as to identify the heavy metal in water of 3rd Drainage Canal and 7 and General Drainage Canal. The historical monitoring data of 3rd Drainage Canal and the 7th Drainage Canal is the routine monitoring results of Bayannaoer Environmental Monitoring Station from 2006 to 2010. The historical monitoring data of heavy metal in General Drainage Canal is routine monitoring results from 2002 to 2010. Field monitoring data is the sample monitoring results on two consecutive days in Aug. 2010. The sampling points are respectively at the water intake of water reclamation plant on 3rd Drainage Canal, water intake of water reclamation plant on 7th Drainage Canal, water intake of Huhe town water reclamation plant on General Drainage Canal upstream, and water intake of Ganqimaodu water reclamation plant on General Drainage Canal downstream. 3rd Drainage Canal and 7 and General Drainage Canal heavy metal monitoring results can be seen in table 4.2-19-table4.2-22.

The heavy metal Hg Pb Cu in General Drainage Canal are evaluated by the method of Standards Index. 3rd Drainage Canal and 7 and General Drainage Canal heavy metal evaluation results can be seen in table4.2-23-table4.2-26.

standard index values are far less than 1; In 3rd Drainage Canal water field monitoring, Pb, Cr+6, Cd and Cu are not detected, and As, Hg, Zn, Fe and Mn standard index values are far less than 1. The heavy metal content in 3rd Drainage Canal water is low and satisfies the IV type water standard of national Environmental quality standards for surface waterGB3838-2002 .

y� From 2006 to 2010, in 7th Drainage Canal water, Pb and Cd are not detected, and As, Hg and Cr +6 standard index values are far less than 1; In 7th Drainage Canal water field monitoring, Pb, Cr +6, Cd and Cu are not detected, and As, Hg, Zn, Fe and Mn standard index values are far less than 1. The heavy metal content in 3rd Drainage Canal water is low and satisfies the IV type water standard of national Environmental quality standards for surface waterGB3838-2002 .

y� From 2002 to 2010, in General Drainage Canal water, Pb is not detected, and As, Hg, Cr +6, Cu, Zn and Se and so on standard index values are far less than 1. Except 2009 Yindingtu and Meilin monitoring stations are out of limit occasionally and over-limit ratio is 17.6%, other years and monitoring station the Cd is not detected in General Drainage Canal water. The over-limit is due to individual enterprises’ illegal pollution discharge. In General Drainage Canal water field monitoring, Pb, Cd and Cu are not detected, and As, Hg, Cr +6 , Zn, Fe and Mn standard index values are far less than 1. Seen from historical monitoring data and field monitoring results, the heavy metal content in General Drainage Canal water is low. Enhance environment monitoring and ensure the waste water of industrial enterprises reach the standard. The heavy metal content in General Drainage Canal water satisfies the IV type water standard of national Environmental quality standards for surface water GB3838-2002

It can be seen from the Table 4.2-31 and Table 4.2-32 that: y� In wet season, DO, CODCr, BOD5, NH3-N and TP in 12 monitoring sections exceed standard partly. DO

pollution index is 0.52-6.40, COD pollution index is 0.98-1.49, BOD5 pollution index is 1.2-2.18, TN pollution index is 0.37-2.81, NH3-N pollution index is 0.087-2.01, and TP pollution index is 0.07-0.87, COD pollution standard indexe are all greater than 1 expect for that in Bapaigan monitoring point, BOD5

pollution standard indexes are all greater than 1, TN pollution standard indexes are all less than 1 expect for that in Xidatan, Bapaigan and Honggebu, and TP pollution standard indexes are all less than 1. This shows that, lake water of Wuliangsuhai lake in wet season is mainly polluted in organic mode, while be relatively light polluted by eutrophic pollutant as N and P.

y� In dry season, all of CODCr, BOD5 and TN in 12 monitoring sections exceed standard, and DO, NH3-N and TP exceed partly. DO pollution index is 3.82-10.00, COD pollution index is 1.06-5.27, BOD5 pollution index is 1.23-7.71, TN pollution index is 1.85-49.89, NH3-N pollution index is 0.31-44.77, and TP pollution index is 1.17-12.6, the lake water has been polluted seriously.

y� The evaluation results of Wuliangsuhai lake indicate that in wet season and dry season that, the water quality of Wuliangsuhai lake in dry season (winter) is worse than that in wet season (summer), it has been polluted relatively heavier in dry season.

y� The water in General Drainage Canal are mainly urban domestic wastewater and industrial wastewater, while the water in Jiiupaigan and Bapaigan are mainly Yellow River ecological water supplement, and less domestic wastewater and industrial wastewater, so the water quality here is relatively better than that in General Drainage Canal, the pollutants import in Wuliangsuhai lake are mainly from General Drainage Canal, therefore, the water quality in western Wuliangsuhai lake is worth than that in eastern.

4.2.3 Assessment of current groundwater environmental quality 4.2.3.1 Monitoring items The evaluation factors of current groundwater environmental quality of wastewater treatment and reuse project and renovated water supply project in Industrial Area are: pH, Ammonia-N, Nitrate-N, NOz-N, Sulfate, and CODMn, As, Cd, Cr VI, Cu, Pb, Zn, Total coliform, Fluoride, Chloride and Total hardness. Every monitoring point of treatment project in Wuliangsuhai lake sea area selects pH value�Salinity�Total hardness (for CaCO3), Ammonia-N, Nitrate, Chloride, As, Cr, CODMn, Cyanide, As, Hg, Fe and Mn as the evaluation factors. 4.2.3.2 Monitoring time and frequency One time and for one day. The monitoring well sampling time of the same hydrogeological unit should be relatively concentrated as much as possible, and the date span should not be too big. 4.2.3.3 Sampling location layout Groundwater monitoring of wastewater treatment and reuse project and renovated water supply project in Industrial Area of this item layout one sampling point at the proposed site. According to "Technical specifications of groundwater monitoring" (HJ/T164-2004) that in generally, it should place 0.2 wells for every 100km2 in plain area (including basin area), because Wuliangsuhai lake is an important water source, combining with its hydrogeological conditions, it should be laid along the seawall, and its sampling point should distribute in a ring. The treatment project in Wuliangsuhai lake sea area laid a total of 8 sampling points.

It can be seen from the Table 4.2-35 and Table 4.2-36 that: y� The proposed site groundwater quality of wastewater treatment and reuse project and

renovated water supply project in Industrial Area mainly exceed standard in inorganic indicators as Ammonia-N, Sulfate, Total hardness, etc., of which, in renovated water supply project site groundwater in Qipaigan, Ammonia-N Standard Index, Sulfate Standard Index and Total hardness Standard Index are 6.2, 1.34 and 1.13, respectively, in wastewater treatment and reuse project and renovated water supply project groundwater in Wulatehouqi County Industrial Area, Ammonia-N Standard Index, Sulfate Standard Index and Fluoride Standard Index are 1.15, 1.27 and 1.51, respectively, in renovated water supply project site groundwater in Qipaigan, Sulfate Standard Index, Total hardness Standard Index and Chloride Standard Index are 2.38, 1.91 and 1.18, respectively, and in wastewater treatment and reuse project groundwater in Wulateqianqi County Industrial Area, Ammonia-N Standard Index, Total hardness Standard Index and Chloride Standard Index are 1.48, 1.46 and 4.36, respectively. This shows that, the water quality characteristics of every proposed project site groundwater is accordance with that of groundwater throughout the region, which is with higher Salinity, but to some extent, there are also exogenous pollution.

y� The water quality of confined groundwater (PumPing well) in Wuliangsuhai lake sea area surrounding is better, Wuliangsuhai lake is the main recharge source of its surrounding groundwater, which is impacted by Wuliangsuhai lake water quality, so its surrounding subsurface water quality is relatively worth, some groundwater indicators in Twelfth field, Ninth field, First field, Fifth work area, Sixth feld and Third field exceeded sdandard, of which, Ammonia-N Sdandard Index exceeded seriously, and its Pollution Standards Index is between 3.13-16.3; Chloride Standard Index in Fifth work area, Sixth feld and Third field all exceeded, and the highest standard pollution index value is 4.4. Therefore, Wuliangsuhai lake

affected significantly on its surrounding groundwater environment, especially for subsurface water quality.

It can be seen that, the content of heavy metals didi not exceed the “Contaminants Control Standard for Agricultural Sludge”, so Saline soil can be improved. 4,2.5.6 Analysis of sediment release Sediment endogenous pollution and its potential ecological risk are two key problems to decide whether to excavate and how deep to excavate. overlying water whether to be affected by sediment endogenous pollution can be reflected by the intensity factor that is target pollutant release rate; Sediments whether to have a higher potential ecological risk can be evaluated by the breadth factor that is occurrence of pollutants which has an important impact on biological in sediment. The former focuses on reflecting the effect on new surface overlying water after dredging, while the latter reflects the possible potential ecological risk on new surface environment. In order to master the details above before scientifically understand the decision of grid water channel excavation; it must understand the spatial distribution of pollutants in sediments and the release of sediment endogenous. In January 2010 the sediment sampling was conducted at 19 sample points in Wuliangsuhai lake, and simulated the release of N and P in sediment under 25 � indoor. Analysis shows that: the release rate of N in other regions of Wuliangsuhai lake was relatively low, excepted for that in 5# sample point (64.34mg/m2 d on average); while the release rate of P were generally higher, excepted for 19# sample point in fringe of dredging area, the release rate in many other regions were about 2 mg/m2·d, of which, the release rate of P at 5# sample point reached 8.76mg/m2·d, P in Wuliangsuhai lake is the restrictive nutrient element for biological, so it would be extremely important to control the release of P in sediment. It can be seen form the result of N and P release (Figure 4.2-7) that, N release in excavation area show forward and reverse, and forward is greater than reverse. Of which, the release rate is relatively faster in vicinity of Xidatan. However, in terms of P release, all of the sampling points released forward, and the release rate was almost beyond 2.0mg/m2·d, which reflected that the entire excavation area had a obvious character of endogenous pollution in sediment. P is the main substance source to the eutrophication of Wuliangsuhai lake,

so it’s necessary to control the pollution of P in sediment with dredging.

Figure 4.2-7 N and P release experiment of Wuliangsuhai lake sediment 4.2.6 Current status of ecological environment 4.2.6.1 Terrestrial environment 1) Soil �1�Soil type According to the second soil survey in 1985, there are more soil types in the city, and there are 14 soil types, 32 subtypes, 94 soil genera and 348 soil species, such as irrigated soil, saline soil, solonetz, aeolian sandy soil, moisture soil, fluvent soil, swamp soil, spodosol, chestnut soil, calcic brown soil, desert grey soil, gray brown desert soil, lithosol, skeleton soil, etc.. �2�The formation and distribution of soil Due to the changing climate and complex topography, soil formations are also different. There are dry and peeling and residual formed grassland in the northern; decadent and accumulative formed sloping fields and valleys; piedmont torrents alluvial fan; wind formed Ulan Buh Desert; Yellow River alluvial formed Hetao Plain and zonal flood land along the river, and its soil parent materials can be divided into the following types: y� River alluvium

Sampling points

Release rate of

P

Alluvial deposit of Yellow River is the main types of city’s soil-forming rock. Yellow River is from Qinghai, Gansu and Ningxia, passing through the Loess Plateau, with rapid flowing, and due to the scouring effect, the river carries huge amounts of silt, and the velocity of flow slow down after into Hetao, then the alluvial deposit deposits with obvious levels in accordance with the regular pattern of “the red mud deposit in slack water and the sand deposits in flowing water”. The major soil of the rive bed in upper river shoal are sandy soil and sandy loam, and that in downriver or depression is red mud-- clay soil. Therefore, the farmers used to say that “deposit red mud far away, and deposit sand nearby”.

y� Irrigation deposit Water of Yellow River contains huge amounts of silt, which flows into irrigation with water, then the farmland is deposited, and the soil layer is thicken. Artificial Irrigation with Yellow River has been conducted for long-term in Hetao, and together with artificial production activities as farming and fertilizing, etc., the unique agricultural soil is formed-- irrigated soil. The irrigated soils have evolved with some human factors as long-term farming, irrigation and sedimentation, etc. after light-colored meadow soil had been reclaimed. The main representative soil of it are sandy soil, desert soil, soft loess, hard loess, red mud, white alkali soil, saline soil, etc.. Yellow River irrigation area of Hetao is west from Ulan Buh region and east to Baiyanhua town, south to the Yellow River and north to the south slope of Wolf Mountain, all of where are distributed with irrigated soil,and the total area of it is 7,561,063 acres.

y� Torrent alluvium Torrent alluvium formed gradually by Yin Mountain flash floods, mixed with gravel sediment, cattle manure and litter. The upper alluvial fan is dominated by gravel and grit, and alluvial plains are mostly sandy loam to light loam. The soil there is deep and fat. Torrent silt plain located in the north of the Ugab River and in the hillside area of eatern Wulateqianqi County, which is in zonal distribution, and the representative soil there is torrent alluvium irrigated soil, and its area is about 296,760 acres.

y� Aeolian deposit Aeolian soil is formed as the wind effect. Which mainly lacated in Ulan Buh region and the edge of Charles Khan Desert in Baiyin city and near the isolated sand dune in Hetao irrigation area, and its total area is about 10,656,739 acres. The representative soils there are sandy soil and sandy loam.

y� Residual soil Residual soils include chestnut soil, brown soil, grey desert soil, gray cinnamonic soil, gray-brown desert soil, etc. Which mainly located in urban mountain dry region, and its area is about 24,087,551 acres. The representative soils there is leaching gray cinnamonic soil, of which area is about 384,459 acres, and located in Wulateqianqi County Erdenii Prague, Bai Yinhua, Sha Degai and Huh Bulag, etc; the area of general gray cinnamonic soil is about 430,958 acres, which is located in above region; the area of brown calcium soil is about 5,850,993 acres, which is located in farming-pastoral area of Wulatezhongqi County and pastoral area of Wulateqianqi County; the area of chestnut silt is about 728,253 acres, which is located in Chaoyang Township, Ming Heung Township and other township of Wulateqianqi County; the area of irrigated meadow chestnut soil is about 98,621 acres, which is located in Da Shetai and other regions of Wulateqianqi County.

�3�Classification area of soil and its physicochemical property �Classification area of soil

The soil in Bayannaoer is classified according to soil texture (V level), there are sand, sandy loam, medium loam, light loam and clay. According to soil layer, the soil is classified into surface soil layer�0—30cm�, subsoil layer�30—60 cm� and bottom layer�60—100 cm�, the soil profile pattern is very complex.

The individual differences of the irrigated soil in Hetao alluvial plain mainly depend on the soil profile pattern, which is composed of various soil textures and their arrangement, and the soil profile pattern not only limits the running of the water and nutrient in soil, but also influences the agricultural production characteristics of soil. The soil profile pattern subjects to 1 meter in depth, and can be classified into three basic layers, that are (The Topsoil, the subsoil, the bottom soil ) top, middle and bottom, according to the thickness of different soil textures, the soil profile pattern has been approximately classified into five categories: y� Homogeneous pattern: the full profile is coposed of uniform texture. Such as Sandy, desert soil, red mud,

etc. y� Thick body pattern: another soil texture with thick layer (>40 cm) under the topsoil, such as Sand drain

two loess, Viscous body two loess, etc.

y� Bandwich pattern: another soil texture with middle thick layer (20—40 cm) in the subsoil layer, such as two loess with sand, two loess with clay, etc.

y� Bottom pattern: another soil texture with middle thick layer under the bottom soil, such as sandy soil with clay bottom, two loess with sand bottom, etc.

y� Three segmental patterns: the three layer segments of top, middle and bottom are three kinds of soil texture, such as two loess with sand bottom and clay, two loess with clay bottom and sand, etc.

Each of above soil profile pattern has a different fertility properties, production characteristics, profile morphology, thickness and layer, and there are also significant differences in each growth layer of soil. The soil types in hill arid area include gray desert soil, chestnut, chestnut silt soil, etc. The soil profile pattern there is more complex, such as residual leached gray cinnamonic soil, which has thicker litter layer on the top, dark gray or black humus layer in sequence and caliche at bottom, all profiles of it are with calcium carbonate reaction, and its parent materials are gneiss and granite. 2) Vegetation The type of the vegetation in Bayannaoer is quite complex due to the influence of climat and topographic condition. It can be classified generally into mountain vegetation, desert vegetation, sandyland vegetation, crops, etc. Grassland vegetation includes dry steppe and desert steppe. Desert vegetation includes steppe desert and stony desert. Its distribution is grassland—dry steppe—desert steppe—steppe desert—desert from east to west. And is meadow vegetation—mountain vegetation—plateau dry steppe—desert from south to north. It showed obvious latitude and longitude zonality, which is consistent with the distribution of soil. In addition, there are psammophytic vegetation, halophytic vegetation, meadow vegetation and other non-zoneal vegetations. Accrding to the vegetation type and floristic characteristics, the vegetation of the whole city can be classified into six districts. Due to the farming, almost no original vegetaions were preserved in Hetao plain, and the existing arbors were planted artificially. Herb is the main vegetation there, of which, there mainly are Meadow vegetations which is dominated by Gramineae, Chenopodiaceae, Polygonaceae and Asteraceae. In the low-lying area there are Halophytic vegetations. Around the sparkling lakes there are aquatic and wetland plants. In the arid area of piedmont there are xeric prickly shrubs. �Meadow vegetation

It is distributed in flood land, and is mainly composed of grasses, such as small reed, Crypsis aculeate, serrated melilotus, Xanthium, etc. The Meadow vegetation in sea water is dominated by floatingheart. There is fewer natural vegetation in alluvial plain, and a small amount of wild plants can be seen only in the unoccupied place of farmland. The main vegetations are dominated by Equisetum ramosissimum, Eragrostis and Chloris. In addition, there are also a lot of Ixeris denticulate, Digitaria, Aster altaicus and Setaria. The wild plants which are dominated by Digitaria and Carex, is distributed in lower and wet area, of which, internodes take root sometimes down to the ground with strong spreading force. Xanthium and Chenopodium album L., which consume large amounts of nutrients, are the main weeds in the farmland. In the flat area there are Callitriche Verna, Barnyard grass and Semen Cuscutae. Wild plants which are dominated by Reeds and Barnyard grass are distributed in the shallow depression. The root of reed is corm, and its regeneration capacity is very strong, which prevails over other weeds; the symbiosis grasses include Barnyard grass, Bolboschoenus maritimus and Imperata. Wild plants which are dominated by Imperata, Drought Polygonum, Equisetum ramosissimum and Reeds, are distributed in flood plain, river channel, and sandy soil with high groundwater or coarse sandy meadow soil with slightly saline soil. Many of the Imperata are wild, and have strong growth vigor, which plays a good role in fixing the sand and diking the dam. Drought Polygonum grows in river often flood areas, and willow is its symbiosis grass.

�Halophytic vegetation

The vegetations, which are distributed in the saline soil with hight salinity, include Suaeda, Kalidium foliatum, Red Woodsorrel�Karelinia caspica�, small reed, Polygonum sibiricum, Alkali grass, Allium fistulosum, basio, stubbed rock grass, etc.. The vegetations which are are distributed in less saline areas include sea milkweed, Chinese tamarisk and Halerpestes ruthenica. And the vegetations which are are distributed in lowland saline soil includesalt absorption�suaeda salsa�, which has strong salt tolerance

and adapted to wide rang of area. In the salt accumulation area there is Nitraria tangutorum�jujube �. And in the edge of depressions where are easy for salt accumulation there is saline Chenopodiacea.

�Aquatic vegetation

It is mainly distributed in water zone or moat, the common species include Reed, Typha, yagara and Bolboschoenus maritimus, along the river bank, there are willow and Chinese tamarisk.

�Desert vegetation

There is Agriophyllum squarrosum in the wandering dune�and in the fixed dune or sandpile, there mainly is Nitraria tangutorum, and a small amount of Achnatherum sptendens. In the area with thin sand layer and higher humidity, there are Alopecuroides L, Agriophyllum pungens, Artemisia desertorum, Licorice, Inular flower and Peganum nigellastrum.

�Farmland weed

Hetao plain is irrigated agricultural area. The main weeds of summer crops include Plaque bamboo, Wild Oats, Vetch, Chenopodium album L., etc.. The main weeds of autumn crops include Agropyron, Calamagrostis, Reed, Cirsium setosum and Thistle.

�Desert grassland vegetation

It is mainly distributed in the foothills terrace of Wolf Mountain�composing of drought-tolerant small semi-shrub grasses. The common species include Caragana stenophylla, Saffranine, Pearl, Artemisia frigida, Ziziphus jujube, Caragana intermedia, Lamerei and Nitraria tangutorum.

3) Wild plants The climate in Bayannaoer is cold, drought and windy, and precipitation there decrease gradually from southeast to northwest, which led to that from southeast to northwest the vegetation taken on the distribution series of the dry steppe – the desert steppe – the steppe desert - the desert in sequence. And of which, the desert steppe and the steppe desert make up the main body of zonal vegetation in this area. It is quite lacking of wild plants in Bayannaoer, and the mian plants there is Xerophyte, there are about 94 families 378 genera and 918 species of wild plants, of which, there are 7 families 7 genera and 12 species of Pteridophyte, and the seed plants are remained. The Herbs are the main seed plants there, and there are 728 species of Herbs, which are dominated by Perennial herbs in total of 566 species, and account for 61.65% of the total number of wild plants. In addition, there are 36 families 78 genera and 178 species of xylophyta, most of which are shrubs, and only 31 species of arbors. 4.2-40 The statistical table of wild plant in Bayannaoer City

The total number of wild plants in Bayannaoer is not rich, but there are more families and genera. The total number of wild plants there is 40.2% of that of Inner Mongolia Autonomous Region, while the number of sepecies there is 73.4% of the total number of families. Thus increases the complexity of plantage, and plant species are more concentrated in a small number of plant families and genera, which led to a lot of single, few species, genera and families. The wild plantage in the city contains 49 single subjects, which account for 52% of the total number of the subjects, in which, there are 28 single species, more than 20 species of 12-family, in total of 643 species of plants, which account for 67.4% of the total number of wild plants in the city, of which, there are 430 species of plants in Compositae, Gramineae, Leguminosae, Rosaceae and Chenopodiaceae, accounting for 45% of the total number of wild plants in the city. There are 196 genera of single species, while only 9 species of genera more than 10, of which, there are 26 species of Artemisia which is the most, and

secondly, there are 23 species of Astragalus and 22 species of Wilt Potentilla, Carex, Allium, Polygonum, Oxytropis and Saussurea are remained. Hetao plain is located in the southern border city, the vegetation type there is the steppe desert, and there are about 200 species of wild plants, mainly are farmland weed, and aquatic, salt and sand plants, most of wild xylophyta are distributed in shoaly land along the Yellow River, depression before the hill and depression of ancient river, where there mainly are Populus euphratica, Elaeagnus angustifolia L., Elm, Chinese tamarisk, a variety of shrub willow, Myricaria germanica, Nitraria tangutorum, Caragana intermedia, Kalidium foliatum, etc.. In the plain farmland, there are Alopecuroides L, Taraxacum, Chenopodium album L., Xanthium Fructus, Lactuca chinensis and Eragrostis poaeoides; in the waters, there are Reed, Typha, Bolboschoenus maritimus, Duckweed, etc.; in the alkaline land, there are a variety of grasses as Salsola ruthenica and so on. There are more than 150 species of resources plants, of which, more than 130 species can be feed and more than 100 species can be used medicinally. The common species include Taraxacum, Patrinia villosa, Plantain Seed, Semen Cuscutae, Cirsium setosum, Kochia scoparia, Xanthium Fructus, Capillary artemisia, Alopecuroides L, etc. 4) Wild animals The climate of Bayannaoer is dry and cold, and the vegetation there is dominated by low vegetation and shrubs, and there is with high proportion of sandy and gavel surface, so the natural condions there is harsh, and there belongs to the Palaearctic in Asia and Asia’s new Mongolian border area based on geographical divisions on the animal. Due to the limit of natural condition, the wild animal species there are lacking. According to incomplete statistics, there are 7 orders, 15 families and 49 species of animals within the city, which is 43% of the total number of animals in Inner Mongolia Autonomous Region; there are 17 orders, 44 families and 199 species of birds, which is 55% the total number of birds in the Autonomous Region; There are 13 species of reptiles; 4 species of batrachia; and many other insects. Due to the effect of the long-term human activities, wild animals in Hetao plain had disappeared, only over ten kinds of rodents existed in this plain, such as hamster, jerboa, gerbil, field mouse, etc., as well as rabbit, pika and so on. Many kinds of lizards can be found everywhere on isolated sand, as well as snakes and hedgehogs, and dozens of species of birds, such as swallows, warblers, sparrows, crows, upupa epops, long tailed shrikes, pigeons, woodpeckers, cuckoo, quail, bustard, eagle, etc. There are also muskrat living in every waterspace. Wuliangsuhai lake, at the eastern end of Hetao plain, is an important place in western Inner Mongolia for migratory birds to stop for a rest, for waterfow to moult and to reproduce. According to incomplete statistics, there are more than 150 species of birds in this area, which include Whooper Swan, Mute Swan and other birds under State protection( category II), and 97 species under “Sino-Japanese agreement on protection of migratory birds and thier habitats”. The most birds in this area are migratory birds or passing migrant birds with going in winter and coming in summer everyyear, and due to the protection of bird resources, Municipal Government issued a Notice in 1984 to protect bird resources of Wuliangsuhai lake, and this area was designated as a suspended hunting area. 5) Soil erosion The soil ersion areas of Bayannaoer are distributed within Wulateqianqi County, Wulatezhongqi County, Wulatehouqi County and Dengkou County, which belongs to Yellow River basin and inland river basin. There are 35 townships and Sumu in this area, the total population there is 192 610, and the population density is 9/ km2. The natural features of soil ersion area are divided into rocky mountain area and windy and sandy area. The rocky mountain area is used to call arid mountain area, and its total area is 18687 km2, all of which are soil ersion area, this area is located between 106°08’—109°45’E. Longitude and 40°26’—42°20’N. Latitude. The windy and sandy area mainly refers to Ulan Buh Desert within Dengkou County, and its total area is 2747.2 km2, which is located between 106°11’—107°06’E. Longitude and 40°46’—40°08’N. Latitude. The soil ersion mainly are wind erowion, which is more in winter, and water erosion, which is more in June and July. The annual erosion modulus is 2527-6075t/ km2.

4.2.6.2 Existing condition analysis of biological diversity in Lake Wuliangsuhai 1) Zooplankton (1) Role of zooplankton

Zooplankton play a key role in the material cycling and energy flow of the aquatic ecosystem. It has a significant impact on carrying capacity and biological resource recruitment in the aquatic ecosystem as follows: �Zooplankton feed on phytoplankton and micro-organisms, therefore, they can purifiy water. �Zooplankton dominant species are used to assess water quality, therefore, zooplankton can be used as indicators for humification of the aquatic environment. � Zooplankton are also food sources for fish fry and mature fish. � Fish productivity of aquatic ecosystem is determined by the zooplankton species diversity, abundance and biomass. (2) Zooplankton survey in 2004-2005

Zooplankton community composition and dominant species A, Zooplankton community composition in the whole lake and features of dominant species

There are totally 4 categories and 62 species of zooplankton in Lake Wuliangsuhai and there are 33 species of rotifers at most, 16 species of protozoa, 9 species of copepods and 4 species of cladocerans. (See Table 4.2-29)

B, Zooplankton community composition in small sea and features of dominant species The small sea areas occupy 36km2. There is about 10km2 shallow in the northeast. The areas where small sea connects with lake are marshlands and reedlands. There are 20km2 of reedlands and 6km2 of marshlands. Water exchange takes a long time between small sea and the lake. Therefore, the water is relatively stable. The average water depth is 0.5m, not deep. According to the survay at site 1 and site 2, there are totally 4 categories and 60 species in small sea. Among these, there are 32 species of rotifers at most, 16 species of protozoa, 8 species of copepods and 4 species of cladocerans.

C, Nature Reserve - zooplankton community composition in core areas and features of dominant species There are 16 km2 of core areas and average water depth is 1.2m. Most of the areas are open waters in core areas. There are a small number of reeds in the northwest and south. According to the survay at site 3, 4, 5, 6, 7, There are 4 categories and 49 species in core areas. Among these, there are 26 species of rotifers at most, 10 species of protozoa, 9 species of copepods and 4 species of cladocerans.

Zooplankton abundance and biomass There are high zooplankton abundance and biomass in Lake Wuliangsuhai. Since some of zooplankton are large and some are very small, therefore, they are divided into 2 parts when counted: large zooplankton (including cladocerans, copepods, nauplii and rotifers) and protozoa. The annual average abundance of large zooplankton and protozoa are respectively 687 L-1 and 2.508×l04 L-1. The annual zooplankton biomass is 3.624 0 mg L-1 on average. See Table 4.2-13 for zooplankton abundance and biomass:

Fig. 4.2-8 Abundance and biomass of large zooplankton

Zooplankton biomass and abundance in small sea is higher than that in the whole lake, while zooplankton biomass and abundance in the core area is lower than that of the whole lake. See details in Fig. 4.2-9.

/ Fig. 4.2-9 Zooplankton abundance in small sea and core area

Fig. 4.2-10 Zooplankton biomasses in small sea and core area � Seasonal changes of zooplankton abundance and biomass

Abundance of protozoa and large zooplankton in Lake Wuliangsuhai reaches the highest level in summer with an average abundance of 1 874.05 and 3.978 × 10 4L-1 respectively. And the second highest abundance appears in spring, respectively 809.83 and 3.881×10 4 L -1. Lowest abundance of protozoa appears in autumn with an abundance of only 0.693 3 × 104L-1, while the lowest abundance of large zooplankton appears in winter with an abundance of 12.21 L-1. The zooplankton abundance and biological changes in samll sea and core area are of the same trend with that in the whole lake.

3) Evaluation methods

It has significantly valuable to take advantage of zooplankton community structure, biomass changes and distribution of dominant species to monitor and evaluate water environment. This method has been used for long both at home and abroad. It is more objective to evaluate the eutrophication and pollution states by zooplankton species, density and diversity. After a comprehensive survey of 211 inland waters in China, Zhihui He has discussed in detail the nutritional type classification of Chinese lakes and reservoirs. He put forward a standard to evaluate the water trophic level by zooplankton biomass. The standard are as follows: 0.16-2 .19 mg/L (average 0.96 mg/L) for the poor trophic level; 0.28-17.60mg/L (average 2.10 mg/L) for the medium trophic level; 0.59-9.52mg/L (average 3.59mg/L) for trophic level; According to the investigation at the Yuqiao reservoir, Mingde Li concluded the annual average zooplankton biomass in non-ice period: <1 mg / L for the poor trophic level; 1.1-3.4 mg / L for the medium trophic level; 3.5-8.0 mg / L for the high trophic level; > 8.0 mg / L for the super trophic level. (3) Evaluation results According to the above evaluation standard, annual average zooplankton biomass of Lake Wuliangsuhai is 3.624 0 mg / L, changing in the range of 0.220 7-7.809 9 mg / L, Water in Lake Wuliangsuhai is in trophic level. The annual average biomass of small sea and core area are 4.424 0 mg / L and 3.224 0 mg / L. It is obvious that the trophic level of small sea is higher than that of core area. The number of zooplankton species in Lake Wuliangsuhai are rotifers > protozoa> Cladocera> copepod. The number of average zooplankton biomass are copepods> nauplii> rotifers> Cladocera> protozoa. Zooplankton abundance and biomass are at its highest level in summer and spring, but decline sharply in autumn and reach to lowest level in winter (except protozoa). The main reason is that local temperature declines sharply. Then there comes the cold winter. 2) Benthonic animals (1) Role of benthonic animals Benthonic animals are one important composition of freshwater ecosystem. It is theoretical significant to learn the structure and function of the ecosystem. Benthonic animals can also be used as natural food for economic aquatic life, such as fish. Some of the benthonic animals are of high economic value themselves (such as river crab and etc.). In addition, the benthonic animals are also often used as biological indicators for environmental monitoring. With this method, not only the water quality can be reflected over a period, but also synergic and antagonistic effects of the pollutants can be reflected in the water and namely the comprehensive toxicity of each pollutant. Therefore, benthonic animals can provide valuable reference to prevent pollution and protect biodiversity. (2) Survey of benthonic animals � Community composition and dominant species of benthonic animals

2 sampling surveys are carried out in August and October. Total 11 species of benthonic animals are found. They belong to 3 phylum, 3 classes and 4 families. Among them, there are 8 chironomidaes of arthropoda, 1 lymnaeidae and 1 planorbidae of mollusca, 1 tubificidae of annelida (See Table 4.2-31). The community composition of benthonic animals in small sea and core area are the same.

1 Abundance and biomass of benthonic animals According to the surveys in August and October, 2004, the average abundance of benthonic animals in Lake Wuliangsuhai is 3 031.4 m2, among which the abundance of chironomidae is the highest, occupying 93.58� of the total. The next is the mollusca with 6.07� and there are very few oligochaeta, only 0.35�. The average biomass of benthonic animals is 71.672 g m2. The biomass of chironomidae is at most with 50.30� of the total. The biomass of mollusca takes up 49.64� and there are almost no oligochaeta, only 0.06�of the total.

Fig. 4.2-12 The abundance and biomass of benthonic animals Abundance of benthonic animals in small sea is much higher than that in core area, 1474.2L-1 of chironomidae, 188L-1 of mollusca and of 10.9L-1 oligochaeta more, nearly 10 times.

Fig. 4.2-13 Abundance of benthonic animals Biomasses of benthonic animals in small sea is also much higher than that in core area, 13.6mg L-1 of chironomidae, 112.7mg L-1 of mollusca and 0.128mg L-1 of oligochaeta more, nearly 12 times.

Fig. 4.2-14 Biomasses of benthonic animals (3) Evaluation methods of benthonic animals Benthonic animals are one of the important compositions of freshwater ecosystems. They are very sensitive to pollution and can reflect change of water quality more directly; therefore, they are often used as biological indicator of water conditions. According to the classification of Carlander in 1952, if biomass of benthonic fauna in reservoir are between 0.20-1.70 g/m2, the water are classified as poor trophic type, 2.50-6.25 g/m2 as medium trophic type and 10.00-25.00 g/m2 as trophic type. In 1980, Russian scholar A.H. Sayyaf classified the reservoir eutrophication in Soviet Union into 5 types as follows : <1.5 g/m2�1.5-3.0 g/m2�3.0-6.0 g/m2�6.0-12.0 g/m2 and >12.0 g/m2.

(4) Evaluation results of benthonic animals The average biomass of benthonic animals in summer and autumn are up to 71.672 g/m2 in Lake Wuliangsuhai. Water in Lake Wuliangsuhai during the two seasons is in trophic level. The biomass in small sea and core area are 84.4237 g/m2 and 62.2432 g/m2 respectively. The trophic level of core area is lower than that of small sea. The sequences of average benthonic animal biomass are: chironomidae > mollusc> oligochaetes.

3�Phytoplankton (1) Role of phytoplankton Phytoplankton is autotrophic plankton. They have chlorophyll or other chromatophore, which can absorb sunlight energy (solar radiation) and carbon dioxide for photosynthesis to synthesize organism (mainly carbohydrates). Therefore, phytoplankton is the main productivity in water and also the basis for food chain and trophic structure. Some phytoplankton can also be used as indicator for environmental monitoring. Comparing with the physiochemical conditions, trophic level can better reflected by the density, biomass, species composition and diversity of phytoplankton. (2) Phytoplankton survey � Phytoplankton community composition and dominant species

With sampling in spring, summer, autumn and winter, it is preliminary known that there are 7 phylum and 58 genera in Lake Wuliangsuhai. There are 22 genera of chlorophyta at most, accounting for 37.9�of total. Bacillariophyta comes the next with 14 genera, accounting for 24.1�. There are 13 genera of cyanophyta, accounting for 22.4%. The numbers of chrysophyta, cryptophyta and euglenophyta are small, 4 genera, 2 genera and 2 genera respectively, accounting for 6.9%, 3.4% and 3.4%. There are only 1 genera of pyrrophyta at least, accounting for 1.7% of the total (Fig 4.2-15). All above phytoplankton communities can be found in small sea and core area. Table 4.2-32 Phytoplankton composition

See Fig.4.2- and 4.2-16 for the all algae density and biomass percentage.

Fig. 4.2-15 Algae biomass in Lake Wuliangsuhai Annual average abundance of phytoplankton in small sea and core area are 53.4×106 ind L-1 and 29.84×106ind L-1. The abundance of phytoplankton in small sea are 24.56×106ind L-1 more than that in core area.

Fig. 4.2-16 Abundance of all kinds of algae Average phytoplankton biomass in small sea and core area are 40.14mg L-1 and 20.04mgL-1. The biomass of phytoplankton in small sea is 20.1mgL-1 more than that in core area.

Fig. 4.2-17 Biomasses of different types of algae � Seasonal changes of phytoplankton density and biomass

It is known from Fig. 4.2-18 that seasonal density changes of cyanobacteria, chlorophyta and diatom chrysophyta are the same. The density is relatively high in spring and reaches its highest level in summer and falls to the lowest level in autumn and begins to increase again in winter. The density of chrysophyta, cryptophyta and euglenophyta are up to its highest level in spring and then decrease gradually to its lowest level in winter, almost zero. (Density of chrysophyta increase a little bit) There are only a few pyrrophyta found in summer and winter. Almost no pyrrophyta can be found in spring and autumn. In addition, chrysophyta is the dominant one in spring with the largest density. But summer is overwhelmingly dominated by cyanobacteria and the situation continues until winter comes. It is known from Fig. 4.2-19 that the seasonal changes of biomass and density are basically the same. Chlorophyta and diatom chrysophyta are the only ones, of which the seasonal changes of biomass and density are different in spring and summer. In additional, euglenophyta has the largest biomass due to its large number and body. In summer, cyanobacteria increase rapidly to its highest level and take place of euglenophyta and cryptophyta. In autumn and winter, most of other algae will die and biomass of diatom chrysophyta is the largest of all. Throughout the year, diatom chrysophyta has the smallest changes in biomass and density, while changes of the other 6 algae are large.

Fig. 4.2-18 Seasonal changes in algae density

Fig. 4.2-19 Seasonal changes of algae biomass (3) Evaluation method of phytoplankton Since different waters are suitable for different algae, the algae species can be used as the indicator to evaluate water trophic level. In 1949, Nygaard put forward the theory PCQ (phytoplankton compound quotient) and it was used to reflect the ecological status of the lakes and have achieved good results. Ott & Laugaste (1996) further developed the formula for the evaluation of lakes in Estonia. The evaluation accuracy has been further improved. The formula is as follows:

PCQ = *+ *+ *+ *+ *+1*+ *+1

In the formula�* represents number of different kinds. See table 4.2-33 for its eutrophication state classification.

Table 4.2-33 Classification of lake ecological status by PCQ (Eutrophication state) PCQ (Poor trophic state) <2 (Mesotrophic state) 2-5 Eutrophic state) 5-7 (Ultra-eutrophic state) >7 (4) Evaluation results of phytoplankton This formula is used in the article to evaluate the trophic level in Lake Wuliangsuhai and it is calculated that PCQ value of the lake is 6.6, which means Lake Wuliangsuhai is in eutrophic state. The PCQ value in small sea is 7.3, which means water in small sea are in ultra-eutrophic state. The PCQ value in core area is 5.7 and the water is in eutrophic state.

y� According to the research results, phytoplankton density throughout the year are: cyanobacteria>

chlorophyta > chrysophyta > diatom chrysophyta > cryptophyta > euglenophyta> pyrrophyt. The biomass of dominant species are euglenophyta > chlorophyta > cyanobacteria > diatom chrysophyta.

y� Lake Wuliangsuhai is located in the North China, the weather of which has following features: dry and cold, large difference of annual temperature, high temperature in summer, long and cold in winter. Therefore, algae density and biomass change greatly, high in spring and summer, but low in autumn and winter. In addition, seasonal change of diatom chrysophyta is relatively stable, which may be because diatom chrysophyta is not very sensitive to climate impact.

y� According to the PCQ formula results, it is known that water in Lake

Wuliangsuhai is in eutrophic state, which is caused by the following 4 reasons: y� Irrigation return flow from Hetao irrigation region: as of now, there are 43.7×104 t fertilizer used in

Hetao irrigation region, but the utilization rate is only about 35�. About 28.4×104 t nutrients flow into Lake Wuliangsuhai every year, which has caused the increasing primary productivity of the lake. According to water quality monitoring results in estuary, total average nitrogen content is 1.74

mg/L, 8 times of common international standard. The total average phosphorus content is 0.07mg/L, which is 3.5 times of common international standard.

y� Industrial wastewater: Pollution in Hetao region is very serious due to industrial structure. Paper making and chemical industries are the leading industries in Hetao region, but these industries cause serious pollution. There are a very small proportion of high-tech and low polluting industries in this region. A large number of untreated wastewater flows into Lake Wuliangsuhai through irrigation drainages every year, which greatly accelerate the degree of its eutrophication.

y� Domestic sewerage: A large number of high phosphorus domestic sewerage is discharged directly into Lake Wuliangsuhai from Hetao irrigation region.

y� Pollution from rural areas in Hetao region: every year a large number of human and animal feces and straw putrilage flow into Lake Wuliangsuhai with the rainfall. This also contributes to the pollution.

4�Fish

(1) Species of fish and its faunal features According to fish survey and samples collected in 2000 – 2002 and " China fish retrieval system", it is preliminarily known that the number of fish in Lake Wuliangsuhai are not large, about 8-10 species, belonging to 2 orders, 3 families. There are mainly cyprinid, 5 species, accounting for 62.5%. 2 species of cobitidae and 1 species of catfish exist in Lake Wuliangsuhai, accounting respectively 25% and 12.5% of the total. See Table 4.2-34 for fish survey details in Lake Wuliangsuhai.

The lake has been in natural state till 1958 and the fish stocks during that period are mainly carp, crucian carp, catfish and etc. The number of carp is the most. There are no fishery production, but only individual fish men and seasonal fishing later on. Fishery production started in 1954. With the expansion of fishery production, people begin to cultivate black carp, grass carp,

silver carp, bighead carp and blunt head bream in Lake Wuliangsuhai. But for various reasons, none of the 5 fish stocks have produced stable biomass. As the water environment in Lake Wuliangsuhai changes, the biomass of fish stocks also changes. According to survey, there are 90% carp of the fish catch before 1955, but 50-60% in 1960. After 1960, the percentage of carp in the fish catches decreases year by year. On the contrary, the percentage of crucian carp increases year by year, from 50-60% in 1983 to 78% in 1999. Meanwhile, some other fish stocks gradually disappear or only account for a very small percentage. This change has to do with over-fishing and water environment changes. (3) Evaluation results of fish Comparing with former surveys, the species and numbers decease significantly according to this fish survey. Some of the fish has even disappeared. As of now, there are just a few species of fish in the lake. Most fish is crucian carp, accounting for more than 80% of total. Numbers of all other fish are small and actually not many fish species. Numbers of the crucian carp are much larger than others.

5�Birds According to information collected and field study, there are 181 species and 4 subspecies of birds, belonging to 16 orders, 45 families and 103 genera. In the year 2000, there are 197 species and 4 subspecies of birds, belonging to 17 orders, 47 families and 110 genera in record, while in 2005, the record changes to 221 species and 4 subspecies of birds, belonging to 17 orders, 47 families and 116 genera. Based on previous data and field study, a preliminary analysis is conducted for wetland bird fauna evolution in Lake Wuliangsuhai. Due to the impact of weather and human being, the wetland environment is deteriorating year by year. Species of birds, which likes to live on marsh, increase these years, but species of birds, which prefer living on vast waters, decrease on the contrary. Large numbers of panurus biarmicus used to be resident birds on Lake Wuliangsuhai. But now they are rarely found in field studies. y� Composition of bird fauna

There are totally 1 order, 2 families, 13 genera and 40 species increased from 1995 to 2005. The number of charadriiformes increases 14 species at most and the next is passeriformes increasing 11 species and third is falconiformes increasing 7 species.

Lake Wuliangsuhai is an oxbow Lake and depth of open water is no more than 1m. There is sufficient sunlight under water with a high degree of eutrophication. Therefore, the submerged plants and floating

plants flourish in the water. All these plants have provided a very good place for the aquatic animals to live and feed. So there are many benthonic animals, phytoplankton, insects and their larvae living in the water. They are good food for many kinds of birds. Many phytophagous birds feed and hover around float grass in open water, such as gulls and herons.

Float grass in open water are also the breeding place for birds, which like to build nest on water, such as chlidoniashybridus and coot.

� Reed and cattail areas There are more reed than cattail in reed and cattail areas. Large areas of reed and cattail distribute in the lake in different shapes. The lake is in eutrophication state and suitable for reed. The height of the plants over water surface is up to 5.5-6.0m. Reed areas are not only good places for birds to build nest, brood and hide when moulting, but also feeding places for many birds, such as panurus biarmicus.

� Shoal areas in the lake Most of the shoal areas are surrounded by reed and cattail. Many grasses grow on the shoal. Birds such as vanellus, wagtail and some ducks nest on the shoal. Some passerine birds also feed here, such as redstart. In addition, shoal areas are also places for anseres, umbrette and laridae to rest and spend the night.

�Shallow and marsh area on the coast

Shallow and marsh areas are mostly around the lake and water depth is no more than 40cm. There are sparse reed or cattail and some other water plants. Many of the aquatic animals live in this area. There are large numbers of various worms and insects and their larvae. This is also a living and feeding place for umbrette. Anseres and coot also come here to feed.

�Surrounding areas around the lake and wetland

Surrounding areas can be divided into following areas: salt marsh areas, nitraria tangutorum desert areas, agricultural areas, residential areas and plantation areas.

Salt marsh area: exposed lake bed after water level decreases. When there is sufficient rainfall, it become shallow and marsh land again. There are saline-alkali tolerant plants living in this area, such as kalidium foliatum and suaeda gtauca. Some birds feed in this area, such as wagtail, water pipit, grey-headed Lapwing and etc. Birds such as vanellus, charadrius alexandrinus and etc often nest and brood here. Nitraria tangutorum desert areas: sandy soil on the surface. There are clusters of drought-resistant plants nitraria tangutorum. Sand soils pile up at the root of nitraria tangutorum year by year. Nitraria tangutorum is an ancient mediterranean plant, resistant to salinity and drought with many hard stabs on the surface. This environment is the feeding and living place for birds like lark, laridae and etc. The hard stab is the nesting and feeding place for small birds like malaconotus alius. It is also a haven for birds like partridges to hide from the prey birds. Farmland areas: wheat, corn, sunflower and others are the main corps in the farmlands around the lake. There are birds like sparrow, jackdaw and etc living in this area in spring, autumn and winter. In spring, summer and autumn, the common birds in the farmland are black-headed gull, mallard, grey goose, quail and so on. Owls and other birds of prey rest and hunt in the open farmland. Residential areas: There are many scattered villages around the Lake Wuliangsuhai with at least several families or dozens of families at most. The common species in residential areas are crested lark, hoopoe, tree sparrow, little owl, eurasian collared dove and etc. Plantation areas: There are often some small pieces of the plantation around the village in the plantation. The trees in the plantation are mainly poplar, willow and sand jujube trees. Weeds grow on the ground of the plantation. The birds here are mainly forest dwellers, such as sparrow hawks, falcon, quail, fieldfare, and brambling and so on.

(3) Analysis of ecological distribution of birds y� Numbers of anseres reduce, while the numbers of sandpiper, falcon and songbirds increase rapidly. The

wetland environment in Lake Wuliangsuhai is of high heterogeneity. Spatial and temporal structures of bird community are of unique features due to the appropriate allocation of many kinds of different

landscapes, such as wetlands, shrub steppe and uplands. the original structure is broken down by the marsh acceleration.

Falconiformes birds and waders, such as charadriformes and gruiformes which like to live on wetland, increase rapidly. The species of anseres breeding here is increasing but the number percentage is decreasing on the contrary. Increase of falconiforme indicates that the wetland, marsh, sparse woodland and cultivated land are increasing in this area, but the large and open lake areas are decreasing. The wetland in Lake Wuliangsuhai is the marsh evolution process. Charadriiformes and gruiformes are waders. They brood and feed in wetland, reed beds, grassland and river shoal. From Table 5.6.5-1, it is concluded that there are 10 species of charadriiformes increased from 1996 to 2000 and 4 species of charadriiformes increased from 2001 to 2005. There are 2 species of gruiformes increased. Over the past 10 years, the species of waders increase rapidly. Not only avoset and tringa totanus live in wetland of Lake Wuliangsuhai, but even Greater Painted-snipe from Japan. This proves that the environmental conditions in the wetland are suitable for waders. Therefore, it can be referred that areas of wetland and marshes are becoming larger and larger and marshland evolution has been intensified in past decade, which is in accordance with the actual situation. According to field study, reed areas are occupying 40% of the areas of Lake Wuliangsuhai and the total reed output in 2000 is 30000-40000 tons more than that in 1996. The wetland dominant species in Spring, summer and autumn are passeriformes. Changes in the species and number have a greater influence on the bird fauna in this area. There are 3 species of anseriformes increased from 2001-2005, but anseriformes species percentage decline due to the increase of wader species. migratory birds like Sarcelle, Common Pochard, shoveller duck and gadwall now also brood here. The increase of anseriformes species indicates the wetland in Lake Wuliangsuhai can provide a good place for migratory anseriformes to nest and feed. But the declining percentage of numbers indicates that its dominant position is becoming weaker and weaker. The water environment, which is suitable for its living, is decreasing. During the study in Lake Wuliangsuhai in April September, 2004, it is seen that there are prosperous reed in the lake. The lake is full of water plants. Many spirals in the sunshine are attaching to the water plants and breathing the oxygen. There are a lot of aquatic insects on the water surface. Tens of thousands of insects are flying above the water. Ducks and snipe are feeding on the water where water plants are prosperous. Reed bed is perfect place for the anseriformes to nest and brood, while the open water environment is good food sources. However, the prosperous water plants are is just the reason why open water areas are decreasing. These water plants cause the marsh evolution and the extinction of the lake. If the situation continues to decline, the marsh evolution in Lake Wuliangsuhai will be more serious. At that time, there will be no prosperity of anseriformes any more. These anseriformes could not live in this area due to the large habitat, but smaller and smaller feeding areas.

y� Significant number change in the birds composition

Comparing with the document record in 1980s, the field study finds below changes: � The number of mute swans has increased; � Number of gray geese and mallards continues to decrease; � Number of water birds breeding in the salt marshes, such as Little tern and snipe increase significantly; � It is hard to find reedling parrotbill living around.

Changes in bird number are mainly due to the great changes in the living environment. There are about 200 couples of mute swans breeding in Lake Wuliangsuhai. The number is much more than before. The reason is that fishermen are aware the necessity to protect the birds. There are fewer fishermen to pick the eggs and hunt for birds; therefore, the hatching and survival rate of mute swans is relatively higher. The document (Lake Wuliangsuhai birds record in Inner Mongolia) say that Yinsun Zhang saw 12000 Grey Geese resting in foot of Ural mountains between Hayehutong and Baiyanhua. however, throughout the field study, only 2 Grey Geese and 8 mallards were seen, which is much less than former record. One of the reasons is that the large number of local residents have poisoned geese and ducks and caused the sharply decrease in number. In addition, with the marsh evolution of lakes and increase of salina, numbers of grass or mud nesting birds increase a lot, such as little tern, common redshank, charadrius alexandrinus and Black-headed Gull.

In last decade, bird species are increasing in Lake Wuliangsuhai. But the newly increased birds are mostly charadiiformesand falconiformes living on shallow and marsh lands and desert grasslands. The change trend of birds fauna indicates that wetland in Lake Wuliangsuhai is shrinking at a startling rate. The marsh evolution increases and areas of open water is becoming smaller and smaller. Shallow marsh areas are increasing. Due to these reasons, the numbers of snipe increase greatly and numbers of anseres also increase. But this excessive reproduction of some plants shall be a temporary phenomenon caused by eutrophication. If marsh and desert evolution situation deteriorate even further, these ducks will have no place to live. There is less living space for swimming birds in the decreasing open water areas. Therefore, the numbers of anseres will inevitably decrease. Panurus biarmicus is a passerine bird, tiny and pretty lovely, mainly feeding on reed seeds. There used to be a great number of panurus biarmicus in Lake Wuliangsuhai and most are resident birds. However, no one is seen during field study in 2004-2005. This may be because tall plants over the ice as reed and cattail are all cut harvest and no panurus biarmicus live here in the winter.

(4) Evaluation result Natural environment breeds life of biological species. On the contrary, biological species reflect characteristics of natural environment. Birds are very sensitive to environmental changes; therefore, they can be used as indicators to environment evolution. There are many changes of bird composition in Lake Wuliangsuhai during past decade. Due to the rapid spread of water plants, sharp decrease of open water areas, increase of marsh areas and speed up of the marsh evolution, changes of bird species, numbers and community structure in past decade and near future are warning us that: there are serious wetland environmental crisis in Lake Wuliangsuhai. It is hard for the ecosystems to maintain the order by its own self-control ability. Biological diversity will be gradually destroyed. Therefore, scientific management is needed to protect the wetland and exploitation shall be reasonable, so that the lake can function properly and sustainably. 4.3 Balance analysis on the project water resource 4.3.1 Balance analysis on the regional water resources 1�Current status of water resources In recent years, the average water resource capacity of the city in several years is 5,574,200,000 m3,where the surface water resource capacity is 4,779,100,000 m3�which is mainly composed by 4,674,800,000m3 water from Yellow River ,the secondary water resource is from surface runoff capacity with 104 ,300,000 m3 that mainly in mountain dry region�,the underground water capacity is 2,419,600,000 m3, in the underground water resources, the annual production volume is 850, 000, 000m3.For water resource conditions in Bayannaoer please see table 4.3-1.

Take the normal year 2008 as an example, the total usage water capacity in the whole year is 4,888,800,000 m3,where the total water consumption in the agriculture is 4,714,400,000m3,which account for 96.4% of the total water consumption; the total water

consumption in industry is 95 800 000 m3,which account for 2.0%the total water consumption; the water consumption for living is 78 600 000m3,which account for 1.6% of the total water consumption. The total water consumption volume of the whole city in 2008 is 3,381,200,000 m3,the comprehensive water consumption rate is 69.2%�The water consumption in agriculture, industry and living are respectively: 3,276,900,000 m3, 48, 200, 000 m3 and 56, 100, 000 m3. The total discharge volume of waste water of the whole city in 2008 is 70,090,700 t, the discharge volume of waste water is 22,564,000 t. The discharging volume of main pollutants COD is 58525.39t, which has reduced 3366.43t compared with 2007,where the discharging volume of COD in industry is 48506.85t,the discharging volume of COD in living is 10018.54t;the discharging volume of ammonia nitrogen is 1902.49t,which has reduced 669.51t compared with 2007, where the discharging volume of ammonia nitrogen in industry is 564.87t,the discharging volume of ammonia nitrogen in living is 1337.62t. 3�Water quality of water resource Carry out assessment on the water quality of rivers of the whole city in 2008 according to the GB3838-2002 Surface Water Quality Standards, the water quality of water run into the Ulansuhai from the general drainage ditch can reach Class V, the main items that exceed the standard are permanganate index, COD, ammonia nitrogen, fluoride and mercury, the average annual mineralization degree is 1.700g/l,which has increased 0.08g/l compared with 2007;the water quality in Ulansuhai is Class V and belong to organic contamination, the main items that exceed the standard are COD, permanganate index,BOD5,TP, total nitrogen, ammonia nitrogen etc.. Carry out evaluation according to the class V water quality of surface water, the exceeding standard rate of BOD5 in the whole year is 66.7%,the exceeding standard rate of COD is 50%,the exceeding standard rate of total nitrogen is 33.3%,the exceeding standard rate of total phosphorus is 16.7%. On the aspect of nutrition, the water body of Ulansuhai is heavy eutrophication, where the total nitrogen has reached heavy eutrophication level; the total phosphorus has reached heavy eutrophication level. The average annual mineralization degree of underground water in the Hetao area in 2008 is 3.920 g/l, which has reduced 0.200 g/l compared with 2007.The freshwater area that the mineralization degree of underground water of irrigation area in the drought period of 2008 is less than 3g/l is 5956.6 km2,which account for 56.7% of the total irrigation area�the freshwater area of underground water during the wet season is 5848.8 km2,which account for 55.7% of the total irrigation area, the freshwater area during the drought period is a little larger than those in 2007, the freshwater area during the wet season has a little reduction compared with those in 2007. 4�The existing problems of water resources In recent years, along with the rapid economic development and the rapid increasing of urban population, the resident living water in the urban and rural area over the whole city in 2008 has reached 78, 600, 000m3.Until now, the water quality existing problems in 3 counties of the total 7 counties ,including Wulateqianqi County , Wuyuan county and Wulatehouqi County ,the water for living in the urban and rural area has been significantly affected. Where the water level in the Allah Ben region that is the water source area of Wulateqianqi County, a relatively large groundwater extraction funnel has been formed, the water for industrial production and living of residents in the urban and rural area has existed crisis�good water that meet the drinking water standard for human and animal is lacking in the Wuyuan county, most of the water are brackish water ,the water for living of residents in the urban and rural area has already existed difficulties�for the Dishaiwusu town where the government of Wulatehouqi County is located, the main reason of removing the government of town is due to the extremely lacking of groundwater. So that the shortage of water resources has became the main factor of restricting the city’s economic and social development currently. According to the Yellow River water allocation plan approved by GBF �1987�No.61 issued by state council, the water capacity allocated to the autonomous region in the normal water supply year of Yellow River is 5,860,000,000m3.In October,1999,the president conference office in the autonomous region has initially determined that the water capacity from Yellow River is 4,000,000,000 m3 after the implementation year of water-saving project in the Hetao irrigation area of Bayannaoer according to the water-saving project plan in the Hetao irrigation area. Due to the historical reasons and the actual situation of agriculture water usage in the Hetao irrigation area, the average amount of water from Yellow River in several years is 4,674,800,000m3, based on the water allocation program approved by the country and autonomous region ,now the Hetao irrigation area has introduced 674 800 000 m3 water from Yellow River in each year of which has exceeded the plan. 5�Balance analysis on the water capacity supply and demand

Due to the water demand prediction calculation zone in the first industry agriculture is five irrigation zones, but the water demand calculation zones for secondary industry, tertiary industry, living and ecological environment are administrative divisions in all counties. After conversion, carry out summary on the prediction results of water demand in the first industry, secondary industry, tertiary industry, living and ecological environment respectively according to the irrigation area and administrative division, for results please see table 4.3-2�water resource evaluation on the water source comprehensive management project in Bayannaoer ,Beijing University of Technology ,2010� Table 4.3-2 Water demand and water supply prediction in all administrative divisions

4.3.2 Water capacity balance in Ulansuhai 1) Annual changes of water capacity in or out of Ulansuhai The table 4.3-3 is the incoming and outgoing water capacity statistics for Ulansuhai in 1988-2008,it can be seen from the table that the drainage water capacity from the general drainage ditch ,Bapaigan , Jiupaigan and four truck channels to the Ulansuhai are respectively 0.307 billion-0.627 billion m3 ,0.025-0.062billion m3,0.005-0.036 billion m3 and 0.023-0.103 billion m3 ,the average value respectively are 0.461 billion m3,0.042 billion m3,0.022 billion m3 and 0.044 billion m3,where the general drainage ditch is the truck ditch for drainage, the drainage capacity accounts for 81% of the total water drainage capacity. Average water capacity run from Ulansuhai into Yellow River is 154 000 000 m3 in every year, the net water capacity run from the drainage ditch and truck channel to the Ulansuhai is 415 million m3. The drainage water in the general drainage ditch, Bapaigan and Jiupaigan are polluted by the urban wastewater and industrial and agricultural wastewater, these water should be discharged into Ulansuhai before carrying

out purification through constructed wetland in the biological transition zone. Due to the replenishing water of the four truck channels are relatively clean water from Yellow River, they can be directly flow into the Ulansuhai area without treatment in the biological transition zone.

5 Comprehensive Environment Impact Assessment 5.1 Analysis on Environment Impact during Construction The project to be constructed includes civil works, pipelines, and installation, M&I equipment, etc. During construction, various construction activities, transport and equipment debugging will inevitably generate waste gases, wastewater, noises, solid wastes, etc. and the surrounding environment will be surely impacted, especially the impact of construction noises and dust are the most. The chapter will analyze the pollutions and their environmental impacts. 5.1.1 Ambient Air Impact Analysis Main ambient air pollution sources during construction of the project include odor, dust and vehicle exhausts. 5.1.1.1 Odor Impact Analysis Odors emitted during grid excavation and sediment transport of Wuliangsuhai Lake will impact the surrounding environment. (1) Odor Intensity Level Odor intensity is classified based on odor threshold value. Odor intensity is classified into six levels (see Table 5-1-1) in China. The limitation criteria are generally equivalent to class 2.5-3.5 of odor intensity. If beyond the intensity range, odor pollution will be identified and corresponding measures shall be taken. Table 5.1-1 6-class Classification of Odor Intensity Classification of Intensity

Sensory Intensity of Odor

0 No Odor 1 Vary Faint Oder (Detect threshold concentration)

2 Weak odor which can determine the property of gas (Confirm threshold concentration)

3 Significant odor to smell easily 4 Strong Odor 5 Strong Odor (2) Odor Impact Analysis The project adopts analogy method to analyze the class of odor pollution intensity. y� Refer to Mudanjiang Nanpaozi Dredging Project (dry excavation in summer) and the investigation analysis

of pollution source odor class is referred to Table 5-1-2. Table 5.1-2 Odor Intensity of Mudanjiang Nanpaozi Sediment Dredging (Dry Excavation of Dry Pond) Distance Sensory Intensity of Odor Class Shore Apparent Odor Class 3 30m away from shore Slight Class 2 80m away from shore Slight Class 1 Above 100m away from shore N/A Class 0 y� Nanning Nanhu Lake Treatment Project adopts wet dredging, only slight odor can be smelled around the

lake and no odor beyond 50m. y� Conclusion

�� Through analogy analysis, there will be apparent odor in the lake area during dredging; the odor intensity reaches class 2 with slight odor beyond 30m, lower than limitation criteria (class 2.5-3.5) of odor intensity; and there is basically no odor beyond 50m.

�� There are many residential areas around Wuliangmei Lake, however, all the sensitive point distribution is relatively scattered and beyond 100m, so the grid excavation and dredging process in Wuliangmei Lake area will not impact surrounding residents.

�� In order to avoid odor impact caused by grid excavation and dredging in Wuliangmei Lake area, the removed sediments and trashes shall be transported to local refuse landfills for landfill treatment timely. If sediments be cannot removed and transported timely, load them to straw bags for storage, thus reducing dust and odorous gas emission, avoid impact on the living quality of nearby residents. Furthermore, transport sediments in closed tank wagons to prevent scattering along the way and impacting urban landscaping.

5.1.1.2 Dust Impact Analysis Construction dust mainly includes dust generated by construction vehicle driving, dust in laydown area and stirring dust, etc. (1) Dust Generated by Vehicle Driving According to the introduction of related references, dust generated by vehicle driving covers above 60% of total dust during construction. Dust generated by vehicle driving can be calculated according to the empirical formula below under absolutely dry condition:

Where,

Q ——Dust generated by vehicle driving, kg/km·Vehicle; V ——Vehicle driving speed, km/h; W ——Vehicle load weight, t; P ——Road surface dust, kg/m2.

Road dust generated by vehicles are related to many factors like vehicle speed, vehicle model, vehicle flow, wind velocity, road surface dust volume and others. Table 5.1-3 gives dust volume generated when a 10t truck passes across a 1km road surface according to different road cleanness and driving speed. We can see from Table 5.1-3 that under the same condition of road cleanness, the faster the driving speed, the more the dust volume; under the same driving speed, the more the road dust volume, the more the dust. Therefore, limiting construction vehicle speed and maintaining road surface cleanness is an effective means to reduce dust.

Table 5.1-3 Dust Volume Generated by 10t Truck at different speeds

Dust Volume Vehicle Speed

0.1kg/m2 0.2kg/m2 0.3kg/m2 0.4kg/m2 0.5kg/m2 1.0kg/m2

5km/h 0.0511 0.0859 0.1164 0.1444 0.1707 0.2871 10km/h 0.1021 0.1717 0.2328 0.2888 0.3414 0.5742 15km/h 0.1532 0.2576 0.3491 0.4332 0.5121 0.8613 25km/h 0.2553 0.4293 0.5819 0.7220 0.8536 1.4355 According to preliminary estimate, road dust on construction site within 80-120m range of downwind exceeds Ambient Air Quality Standard (GB3095-1996) Level II Standard, and road dust of transportation spoil within 30-60m range of downwind exceeds GB3095-1996 Level II Standard. (2) Laydown Area Dust Another source of dust during construction stage is wind dust in open laydown area and open site. Due to the construction needs, some building materials and excavated earthwork shall be temporarily piled up. Under the condition of dry and windy climate, dust will be generated and dust volume can be calculated according to the empirical formula of dust in laydown area:

Where,

Q ——Dust volume, kg/t·a; V50 ——Wind velocity at height where is 50m away from ground, m/s; V0 ——Dusting wind velocity, m/s; W——Moisture content of dust particle, %.

Dusting wind velocity is related to particle size and moisture content, so reducing open laydown area, ensuring certain moisture content, and reducing open ground are effective means to reduce dust caused by wind. The diffusion and dilution of dust in air is related to wind velocity and other climate conditions and

related to the sediment velocity of dust as well. The sediment velocity of different particle sizes is referred to Table 5.1-4. We can see from the Table, the sediment velocity of dust increases rapidly along with the increase of particle size. When particle size is larger than 250 m, the main impact range is within the close distance range of downwind of dust generation point, while some tiny particle size of dust has big impact on ambient environment.

Table 5.1-4 Sedimentation Velocity of Different Particle Sizes Dust Particle Size ( m) 10 20 30 40 50 60 70 Sedimentation Velocity (m/s) 0.003 0.012 0.027 0.048 0.075 0.108 0.147 Dust Particle Size ( m) 80 90 100 150 200 250 350 Sedimentation Velocity (m/s) 0.158 0.170 0.182 0.239 0.804 1.005 1.829 Preliminarily estimated according to related data, the dust in dump laydown area exceeds GB3095-1996 level II standard within range of 100-150m downwind. (3) Dust from material mixing Through analogy analysis on dust monitoring data on the construction lime stirring site, near the lime stirring station, the concentration at 50m downwind at TSP hour is 8.10 mg/m3, the concentration at 100m downwind at TSP hour is 1.65 mg/m3, and there is basically no impact at places 150m far away. (4) Construction Dust Impact According to above analysis and preliminary estimate, road dust on construction site within 80-120m range of downwind exceeds Ambient Air Quality Standard (GB3095-1996) Level II Standard, road dust of transportation spoil within 30-60m range of downwind exceeds GB3095-1996 Level II Standard; dust on spool laydown area within 100-150m range of downwind exceeds GB3095-1996 Level II Standard; Through analogy analysis on dust monitoring data on the construction lime stirring site, near the lime stirring station, the concentration at 50m downwind at TSP hour is 8.10 mg/m3, the concentration at 100m downwind at TSP hour is 1.65 mg/m3, and daily average value concentration of GB3095-1996 level II standard are basically met at places 150m far away. According to related test results, if spray water frequently (4-5 times/day) onto car driving road surface during construction, the dust volume can be reduced by 70% or so and get good dust sediment effects. Table 5.1-5 gives the actual test results of sprinkler dust on construction site. Table 5.1-5 Sprinkler Dust Test Result Distance from Construction Source/m 5 20 50 100

No Sprinkler 10.14 2.89 1.15 0.86 Spraying Water 2.01 1.40 0.67 0.60

TSP Concentration Value (Hour Average )/mg·m-3 GB3095-1996 Ambient Air Quality Standard

Level II Standard 0.9

It can be seen from data given in Table 6.1-5, after the sprinkler dust measure (sprinkler 4-5 times per day) is taken, the dust concentration (calculated in TSP) is reduced greatly, and the impact range is also reduced from 5-100m to 5-50m. Within the range of 50-100m, the TSP concentration value of ambient air reaches level II standard of GB3095-1996 Ambient Air Quality Standard (suitable for residential area, commerce, transport and resident mixed area). In general, construction dust will have certain impact on residents, schools, enterprises and public institutions and construction personnel around the construction boundary, among which, construction personnel are affected the most. As the pipe network construction involves a wide range and the range affected by construction dust is wide, construction dust is mainly concentrated on both ends of pipe works and the roads where construction and transport vehicles drive across, however, the distance between project pipe network construction point and residential area and enterprises and public institutions is above 100m. So though construction dust has certain impact on ambient environment, by taking necessary measures, the impact of construction dust will be reduced greatly. And the impact is temporary, along with the execution of landscaping and rehabilitation, the impact will be reduced greatly and even disappear after the completion of construction. 5.1.1.3 Vehicle Emissions

Construction machinery and equipment for the project includes face shovel, back shovel, bulldozer, dump truck, pile driver, and stirrer, etc. The construction machinery uses diesel and gasoline and exhaust emissions by fuel oil mainly includes SO2, NOx, CO and hydrocarbons, etc. Exhaust emissions during construction are referred to Table 5.1-6. Table 5.1-6 Exhaust Emissions during Construction

CnHm: 59.088

As smaller intensity of exhaust emissions and flat terrain which are favorable to waste gas dilution and diffusion, tail gases generated by construction machineries, transport vehicles have small impact on ambient atmospheric environment. 5.1.2 Water Environment Impact Analysis and Assessment 5.1.2.1 Construction Wastewater Environment Impact Analysis During construction, as the execution of site cleaning, pipe laying, concrete mixture, building and installation, etc. a certain amount of construction residual water and spools will be brought. In addition, as a large number of construction personnel will be needed during construction, a certain amount of sanitary wastewater will be generated. (1) Construction Wastewater Main pollutants in construction residual water and spools are COD, SS and petroleum. The analogy data show that the concentration of COD and petroleum are both lower than 150 mg/L for COD and 10 mg/L for petroleum required by level II standard in Integrated Wastewater Discharge Standard (GB8978-1996), but cause SS increased in short time. According to analogy investigation, the concentration of wastewater suspended matters during construction is 500-1300 mg/L, after preliminary treatment of sediment and others, the concentration of suspended matter is greatly reduced and can reach discharge standard after holding for above 2h and will not cause remarkably unfavorable impact on water body. (2) Sanitary Wastewater The calculation formula of sanitary wastewater on construction site is as below:

Q = (k × q × n) /1000 Where, Q——Sanitary wastewater volume, t/d;

k——Wastewater emission coefficient, the project takes 0.8; q——Per capital sanitary household water consumption, L/cap·d; n——Number of daily construction site personnel, cap.

According to analogy data, the COD concentration in sanitary wastewater on construction site is around 300 mg/m3, BOD5 concentration is around 150 mg/m3, and SS is 150mg/l. Water consumption takes 50 L/cap·d for calculation and the calculation results are shown in table. According to the requirements of construction scale and construction period of each pollution project, estimate the construction personnel required and sanitary wastewater emissions, refer to Table 5.1-7.

As all itemized works of the project are not developed simultaneously, actual sanitary wastewater emissions are not the sum of simple addition of figures in above table. From above table, it can be reflected that sanitary wastewater emissions during construction are not big. The existing living facilities near the construction site shall be used for sanitary wastewater emissions during construction as far as possible. The unconditioned area shall be set up with temporary toilets and cesspool on site to collect stools which shall be transported by pumping tumbrel provided by construction companies or consigned sanitation department to wastewater treatment plant for treatment periodically. 5.1.2.2 Assessment of Impact on Water Environment of Grid Excavation and Sediment Release in Lake Area Environment-friendly dredging machineries are used for this work to dredge grid waterways in Wuliangsuhai Lake. Disturbance brought by the dredging will facilitate the mix and exchange between mud and water, causing the increase of pollutants and SS content in water body, as well as the increase of organic matters and nutrients, also interfering the living environment for benthic organism to a certain degree. (1)Analysis on Suspended Matter Diffusion Impact Factors like comprehensive dredging effects and impact on environment. It’s recommended to deploy 0.8~1.2 m3 hydraulic backhole dredgers. For sediments excavation at the upper layer in the area having less aquatic weeds, grab dredgers can be used. Basically, hydraulic backhole dredgers and grab dredgers will conduct stationary operation during the construction. Diffusion mechanism of suspended dredged materials is similar to the diffusion of continuous point source. This environmental evaluation will refer to the forecast results of impact on suspended matters diffusion in dredging operation in relevant lake area of Meiliang Lake under the Report on the Impact on Polluted Bed Mud Dredging Test Work Environment in Tai Lake, where the construction process is similar to that of this work, and the forecast results in which can reflect the impact range of this work. The forecast results indicate that at 50m of excavation circumference, the impact values of suspended matters content in water body are all below 10mg/L. And such impact mainly works on dredging. About one hour after dredging, the content of suspended matters increased artificially will fall off under 1mg/L quickly.

The excavation and dredging can facilitate the mix and exchange between mud and wter in the system effectively, enhance the release of organic matter, TP and TN in bed mud, and cause the increase of contents of COD, TP, and TN in the water body. According to the test data of bed mud resuspension in relevant water body, the disturbance brought by mud excavation will increase the contents of aerobic organic matters, TP and TN by around 10%. Short after mud excavation, due to the effects caused by oxide and hydroxide, the contents of aerobic organic matter, TP and TN will decline gradually to the background level, which will not affect the water body in area being excavated too much. (2)Analysis on Impact of Residual Water at Laydown Area Pollutants in residual water from waterway excavation operation mainly refer to the pollutants contained in the water body of construction area, as well as nitrogen, phosphorus, and heavy metal pollutants enriched in bed mud particles. Controlling the discharge content of suspended matters in waters during construction will control the discharge contents of other pollutants effectively. According to the results of simulation test on silt in Caohai, Dianchi in Table 51-8: Pollutant content in residual water declines as the time of slurry sedimentation increases, but the content of suspended matters might not meet the requirements under Standard-I. If stationary time is shorter than 48h, pollutant content in residual water will exceed Standard-I under Slurry Comprehensive Discharge Standard. According to laydown area design for this work, slurry sedimentation time is normally longer than 48h.

. (3) Analysis on Secondary Pollution of Waterway Excavation Work Bed mud excavation is one of the significant measures to control internal pollution source in the lake. However, bed mud excavation is a large-scale man-made interference which will facilitate pollutant release such as nutrient and heavy metal, bringing negative impact on the quality of water body environment to a certain degree. For bed mud excavation is similar to bed mud dredging, therefore, the Analysis on Risks of Water Environment Quality of Bed Mud Dredging in Tai Lake (written by Liu Aiju, Kong Fanxiang, Wang Dong) can be used for analogy, which indicates that during dredging operation and during a short while after dredging finishes, the contents of total suspended matters, toxic heavy metal ions, nitrogen nutrient and phosphorus nutrient in the water body increase, while the transparency of water body declines. That’s mainly because dredging operation causes resuspension of surface sediments, facilitating the release of nitrogen nutrient, phosphorus nutrient, and toxic heavy metal ions from sediments. Such impact on environment will continue that two months after dredging operation finishes, suspended matters content, heavy metal pollution level, nitrogen nutrient content, and phosphorus nutrient content in the water body start to decline, meaning that suspended matters, as well as nutrients and heavy metal ions suspended matters absorbed in the water body after dredging operation will start to precipitate quickly. However, compared to the situation before dredging, the quality of lake water environment nine months after dredging is not as good as that before dredging. One year after dredging, water body quality improves, and all indicators can’t compete with those before dredging, which means that bed mud excavation will somehow facilitate the improvement and enhancement of lake water body.

5.1.3 Analysis of Acoustic Environmental Impact The construction noise is mainly generated by construction machineries and transportation vehicles. The noise intensity is different in different construction stages, sites and operation types. During construction, there are many construction machineries, besides, the construction is outdoor working without noise reduction measures, and therefore the noise is spread far and the affected area is large. Main noise sources during construction are excavators, transportation vehicles, pipelayers, concrete mixers, dump trucks, vibrators, electric welding machines and bulldozers etc. Main noise sources of machineries and the source intensities are as shown in table 5.1-9. Table 5.1-9 Main Noise Sources of Machineries and the Source Intensities No. Equipment Name Intensity dB(A) 1 Air compressor 110 2 Crusher 97 3 Excavator 79�83 4 Bulldozer 85 5 Loader 85 6 Lifter 72 7 Winder 97 8 Truck (above 10t) 79�83 9 Crane 76 10 Electric saw 90 11 Welding machine 78 12 Grafter 80 13 Pavement roller 84 14 Pile driver 110 15 Vibrator 105 16 Concrete pump 85 17 Dredger 92

(2) Analysis of environmental impact of noise on construction site The analysis of engineering pollution sources shows that the noise sources on construction site are machineries with high noise and during construction, and a lot of machineries are operated on site, and therefore the intensity of single unit equipment source is between 76 dB(A) and 110 dB(A). The construction equipment can not be prevented, because they are used outdoor. The attenuation of noise with the distance increase is as follows:

During construction, the machineries are main noise sources, if not considering the influence of houses, trees and air etc., at 100m away from the boundary of construction site, the maximum noise level is 70 dB(A), while at 500m away, the maximum noise level is 56 dB(A), which basically meet the daytime noise level of construction site. If considering the noise reduction of houses, trees and air etc., the reduced noise is 15 dB(A). At 100m away from both sides of the construction site, the noise level can meet the daytime limit for construction site. No. 3 Drainage Canal Reclaimed Water Supply Works will impact the acoustic environment around the adjacent Shanba Feeding Farm and No. 3 Drainage Canal Wastewater Treatment Plant; No. 7 Drainage Canal Reclaimed Water Supply Works will impact Wuyuan Brick Yard and other enterprises; Wastewater Treatment and Reuse Works of Wulateqianqi County Processing Park will impact the acoustic environment of Shagedan Village; there is a few environmental sensitive spots around other proposed works and the impact of construction noise is little. Therefore, during construction, the operation time of machineries shall be rationally arranged to avoid many equipments with high noise are operated simultaneously as much as possible and to avoid the sensitive period of noise on environment, such as, construction of equipments with high noise shall be arranged at daytime, transportation at night shall be reduced, and construction at night (22:00�6:00) shall be prohibited. The construction activities which must be carried out at night shall be approved by the local environmental protection administration and shall be provided with noise barriers between noise sources and sensitive spots. The table 5.1-10 shows that the level of noise generated by machineries is high; the impingement power is strong even lasting a long period with strong shock, which greatly impact the ambient environment. Only the place 300m or farther away from the construction site can meet the standard of acoustic environmental function zone of Wuliangsuhai Lake. The construction site is at least 2km away from the core zone, and therefore, it will not impact the birds in the reserve area. The above mentioned analysis shows that during construction, try to reduce the man-made noise, adopt proper sound insulation measures, set up construction enclosures, rationally arrange the operation time of equipment with high noise and try to avoid construction at night for reducing the impacts on environment. Meanwhile, select the equipment position and use the natural condition for noise reduction to minimize the noise during construction. 5.1.4 Analysis of Solid Waste Environmental Impact The solid waste generated during construction mainly includes bed mud generated during grid excavation of Wuliangsuhai Lake area, dregs and gravels excavated during earthwork construction, material lost during transportation including sands, stones and concrete etc., and domestic waste produced by construction personnel. (1) Bed mud and waste generated during grid excavation of Wuliangsuhai Lake area The works of this project mainly include excavation works of watercourse in the lake area and construction of temporary pier and mud heap yard. The construction area of grid excavation of Wuliangsuhai Lake area is 2.451×106m2, the bed mud generated is 3.35 million m3. Except for natural reasons (such as blowing, dust falling etc.), main reason of the bed mud is the sediment caused by great soil and water loss, filled by the aquatic plant and the sediment of suspended matter in industrial waste water and domestic wastewater. The moisture content in sludge is high. If don’t adopt proper protective measures, the secondary pollution may be generated. The Bayannaoer Environmental Monitoring Station monitors the heavy metal content in the bed mud. The monitoring result shows that the heavy metal content at all monitoring points meet the GB4284-84 Control Standards for Pollutants in Sludge from Agricultural Use. Thus, the bed mud can be used as the fertilizer. The upper bed mud can be used for improving the saline alkali soil; the lower bed mud is mainly the non-polluted

undisturbed soil about 2.17 million m3, and used for building the artificial island in the lake area. The lower bed mud is consumed internally and not transported outside. In accordance with the tourism planning of Wuliangsuhai Lake, many artificial islands shall be constructed in the lake area. (2) Spoil During construction, spoil will be generated from the earth excavation. During transportation and disposal, the spoil may impact the environment. Based on the estimation, earth in all works of this project is basically balanced without shortage of soil. But the construction of water supply and distribution pipeline network will generate the spoil. During pipe-laying, the soil generated during pipe trench excavation is heaped at one side of the pipe trench. At the bottom of the trench, firstly fill the foundation stuffing with the thickness of 400mm and then laying the pipeline. Therefore, the works spoil volume is at least equal to addition of pipeline volume and volume of foundation depth. In accordance with the estimation of pipeline work earth volume, the spoil volume of works lines of this project is as shown in table 5.1-11. Table 5.1-11 Spoil Volume of Works Lines

(3) Construction Waste The construction waste will be generated due to consumption and desertion of stones, clinkers and building materials during construction of all works. If the construction waste is not be handled promptly, it is not only unsightly and influence the landscape of the city, but also be blown to generate the dust raise phenomenon in gale and dry weather. The soil and construction waste of the works transported outward is common solid waste without the toxic and harmful content. The waste can be used for filling the foundation of construction works specified by the municipal and planning departments, filling the swag or greening along the river for disposal. Rest waste can be delivered to local landfill site. Generally, disposal of the discard will not take the adverse impact on environment. (4) Domestic Waste In accordance with that the construction period is 36 months and the waste is 1.16kg/person·d, the domestic waste volume during construction period of all works is as shown in table 5.1-12. The total domestic waste output during construction is 977.4t which is delivered to the site specified by Environmental Sanitation Administration for disposal.

Total 977.4 During construction, daily life of the constructors will generate domestic waste at certain quantity. If the waste is not disposed promptly, at proper temperature, it will breed mosquitoes and insects, generate fetidity and transmit diseases, resulting in adverse impact on ambient environment. Therefore, the domestic waste shall be promptly delivered to the site specified by Environmental Sanitation Administration for disposal to avoid the impact on ambient environment. 5.1.5 Analysis of Ecological Impact 5.1.5.1 Project Construction Impact of this project on ecological environment mainly refers to the damage of soil and natural vegetation caused by works construction and pipe-laying. (1) Analysis of Soil and Water Loss The construction the reclaimed water treatment facilities, the wastewater treatment reuse facilities and the Wuliangsuhai Lake artificial wetland belongs to the permanent land occupation. The vegetation shall be rooted up for construction of the reclaimed water treatment facilities and the wastewater treatment reuse facilities, resulting in reduction of vegetation coverage rate, which easily causes soil and water loss at little quantity. Besides, the earth excavation and filling change the soil structure, reduce the soil maturation degree, impact the productivity of soil after reclaim, but will not change the land utilization type. The permanent land occupation of the reclaimed water treatment facilities and the wastewater treatment reuse facilities mainly is the wasteland and some is the agricultural land, which will reduce the farm land at certain degree. The construction method of Wuliangsuhai Lake artificial wetland is artificial intensification of the existing reed field without changing the original utilization features of the land. The permanent land occupation of this works takes little ecological impact. (2) Impact of Temporary Land Occupation Construction of the pipeline network belongs to the temporary land occupation. The vegetation within 1-8m of the pipe trench is severely impacted. The crops will be recovered in a short time, but the trees and other vegetation will be recovered in a long time. During the temporary land occupation construction, strict topsoil protective measures shall be carried out to avoid unrecoverable impact. During excavation, the top soil (suggested thickness 30�50cm) shall be collected and stacked separately and the soil and water loss control measures shall be adopted. After construction, firstly fill the subsurface soil back, and then cover the top soil on the surface, and level up the site so as to reduce the impact on soil quality. As long as there is rational planning during construction, timely site cleaning and greening after construction, the adverse impact can be effectively controlled. The disturbance of pipe-laying is low frequent and linear. Its impact is partial, temporary and recoverable after construction. �3�soil and water loss The impact of general project on soil and water loss mainly includes the following two aspects: vegetation damage during excavation of ground surface, resulting in soil and water loss in rainfall; damage of original vegetation caused by the temporary land occupation, resulting in increase of soil and water loss. If the raw

material yard and discarded soil temporary stacking yard are not properly managed, soil and water loss phenomenon in form of sheet erosion and shallow ditch erosion etc. may easily happen. The construction stages of this project in which the soil and water loss may happen mainly refer to ground excavation during pipe-laying, construction of reclaimed water facilities, wastewater treatment reuse facilities and Wuliangsuhai Lake artificial wetland and earthwork excavation. In accordance with the soil and water conservation scheme of all works, the predicted results of soil and water loss are as follows: 1) Wulatehouqi County Processing Park Reclaimed Water Supply Works Area of original topography and ground vegetation damaged during the construction of Wulatehouqi County Processing Park Reclaimed Water Supply Works is 41.31hm2, total area of soil and water conservation facilities damaged is 41.31hm2, total possible soil and water loss is 29,300 t and the newly increased soil and water loss is 20,200 t. 2) Wulatehouqi County Processing Park Wastewater Treatment Reuse Works Area of original topography and ground vegetation damaged during the construction of Wulatehouqi County Processing Park Wastewater Treatment Reuse Works is 13.47hm2, total area of soil and water conservation facilities damaged is 13.36hm2, soil erosion caused by disturbance of the works is 50180t including 49084.96t soil and water loss during construction (including preparation period) and the newly increased soil and water loss is 24192.1 t. 3) No. 3 Drainage Canal Reclaimed Water Supply Works Area of original topography and ground vegetation damaged during the construction of No. 3 Drainage Canal Reclaimed Water Supply Works is 19.66hm2, total area of soil and water conservation facilities damaged is 17.21hm2, soil erosion caused by disturbance of the works is 2208.89t (including spontaneous recovery period) and the newly increased soil and water loss is 826.81t. 4) No. 7 Drainage Canal Reclaimed Water Supply Works Area of original topography and ground vegetation damaged during the construction of No. 7 Drainage Canal Reclaimed Water Supply Works is 42.39hm2, total area of soil and water conservation facilities damaged is 39.89hm2, soil erosion caused by disturbance of the works is 5062.26t (including spontaneous recovery period) and the newly increased soil and water loss is 2160.89t. 5) Ganqimaodu Port Processing Park Reclaimed Water Supply Works The soil and water loss type of Ganqimaodu Port Processing Park Reclaimed Water Supply Works during construction is complex erosion by wind and water (mainly the wind). The important predicted stage of the soil and water loss is the construction period and the operation period. The total disturbed ground area during construction is 62.93hm2, total area of soil and water conservation facilities damaged is 51.77hm2, total possible soil and water loss is 17810.25t, and the newly increased soil and water loss is 12660.02t. 6) Ganqimaodu Port Processing Park Wastewater Treatment Reuse Works Area of original topography and ground vegetation damaged during the construction of Ganqimaodu Port Processing Park Wastewater Treatment Reuse Works is 55.76hm2, total area of soil and water conservation facilities damaged is 55.76hm2, soil erosion caused by disturbance of the works is 12976.20t and the newly increased soil and water loss is 5131.45t. 7) Wulateqianqi County Processing Park Wastewater Treatment Reuse Works The soil and water loss type of Wulateqianqi County Processing Park Wastewater Treatment Reuse Works during construction is complex erosion by wind and water (mainly the wind). The important predicted stage of the soil and water loss is the construction period. The total disturbed ground area during construction is 13.85hm2, soil and water loss area during construction (including preparation period) is 13.85hm2, and that during spontaneous recovery is 7.94hm2. Total possible soil and water loss is 1354.39t, increased by 556.69t; soil and water loss during construction is 586.60t, increased by 312.94t and during spontaneous recovery is 767.79t, increased by 243.75t. 8) Wuliangsuhai Lake Bio-transition Zone Artificial Wetland and Non-point Source Pollution Control Demonstration Promotion Works

9 Wuliangsuhai Lake Grid Watercourse Works 1.41 5.1.5.2 Impact on Landscape Ecology The coverage of this project is large. During the construction of pipeline network and lake area treatment works, the excavation and soil stacking will make the pipeline network laying area in disorder. Although there is the disclosure, the construction site will make the disorder impression; the spill of discarded soil during outward transportation will not only dirty the roads and but also raise the dusts, which will take adverse impact on surrounding landscape. Therefore, the cleaning work on construction site is very important. The impact on landscape during construction is short-term and recoverable. 5.1.5.3 Impact of Wuliangsuhai Lake Pollution Control Works in Construction Stage 1) Wuliangsuhai Lake Grid Watercourse Excavation Works Suspended matters generated during grid watercourse construction will form a high density distributed zone around the construction site, resulting in species and quantity reduction of plankton and zooplankton. However, this impact is reversible. After completion of the works, the impact will eliminate soon. The disturbance of construction of grid watercourse on benthonic habitat will cause damage of habitat for zoobenthos, resulting in stable reduction of biocoenosis structure. Noise and air pollution generated by the construction of grid watercourse will take impact on birds and reduce the species and quantity of plankton and zooplankton, resulting in impact on wading birds. The mud yard and hydraulic fill works will damage original terrestrial vegetation, resulting in the loss of vegetation in species and quantity. 2) Wuliangsuhai Lake Artificial Wetland Works Impact of the works on vegetation mainly refers to the damage of reed caused by land occupation. During construction, channel dredge and trench excavation excavate the subsoil out, which totally change the soil mass structure. During construction, vegetation on the excavation area is all damaged, and the vegetation at both sides of the trench is damaged and impacted at different degree; in the area with severe damage, not only the vegetation but also the soil is damaged, which will impact the further growth of vegetation; in moderate

impacted area, during excavation, rolling and trample of machinery, vehicles and personnel and stack of excavated soil will cause severe damage of the plants and also slightly impact the soil; in slightly impacted area, activities of machinery, vehicles and personnel reduce and the corresponding impact is slight. The wetland restoration works is at least 5km away from the core area of Wuliangsuhai Lake Waterfowl Natural Reserve. The construction area is outside the buffer zone of the natural reserve and will not directly impact the birds and their habitat, but during construction, there will be many machineries and constructors entering peripheral region of the reserve. If the protection is not strengthened, increase of noise of machineries and activities of constructors will indirectly impact the normal foraging and habitat of birds and the reserve. Suspended matters generated during construction of stabilization and sedimentation pond will form a high density distributed zone around the construction site, resulting in species and quantity reduction of plankton and zooplankton. However, this impact is reversible. After completion of the works, the impact will eliminate soon. The disturbance of construction on benthonic habitat will cause damage of habitat for zoobenthos, resulting in stable reduction of biocoenosis structure. Noise and air pollution generated by the construction will take impact on birds and reduce the species and quantity of plankton and zooplankton, resulting in impact on wading birds. 5.1.6 Social Environmental Impact Analysis 5.1.6.1 Impact on Traffic Impact on traffic during construction mainly includes the following three aspects: � road break for pipeline network holds up the traffic; � stacking of soil and road excavation hold up the traffic; � transportation vehicles increase the traffic flow. Main impact of construction on traffic is on road traffic, detailed in table 5.1-14. Table 5.1-14 Impact of Construction on Traffic Construction Item

Works with Impact Impact on Traffic Mitigation Measures

Material transportation

�Increase the traffic flow of city proper and impact the traffic smooth. �Spill of soil, stones and sands during transportation impacts the safety of traffic and damage the pavement.

�Strengthen the traffic dispatch and control to avoid peak traffic. �Strengthen the education of drivers, prohibit to over load, promptly clean the spilled material.

Pipeline construction

Reclaimed water supply and processing park wastewater treatment reuse works

Damage pavement, soil is stacked, impact the traffic

�Construct in stages, and try to complete excavation and backfill in a short period. �Set up temporary road and warning marks and appoint special person to relieve the traffic

Impact of construction of pipeline network on traffic is obvious. Although the staged construction method can be adopted, during construction, there is always some soil to be stacked temporarily, which will impact the traffic along the pipeline and plant area. When pipelines cross the roads, if adopt the trenching method, it may block the vehicles, resulting in great impact on traffic. Therefore, if the geology and soil conditions are applicable, pipe jacking construction method will reduce the impact of road excavation during construction. During this period, bearing force (supporting capacity) of the roads will reduce, and therefore the truck shall be prohibited in a short period, which will impact the traffic. According to estimation, 20 days are needed for pipeline crossing every road, and thus the impact on traffic of this road will last 20 days. Therefore, detailed planning and speed-up construction shall be needed, try to adopt the pipe jacking construction method, work out the temporary route with the local traffic administration before construction, inform the residents in impacted area in advance, set up warning plates on construction site and appoint special person to relieve the traffic. Beside, adopt management strengthening during construction and construction period shortening and other measures to avoid traffic jam. The transportation of raw material (sandstones, cement etc.) and discarded soil will increase the traffic flow in a short period. Therefore, the transportation shall not be carried out in traffic peak, especially the morning and evening peak.

5.1.6.2 Health and Safety This works includes many works, such as reclaimed water supply works, wastewater treatment reuse works and Wuliangsuhai Lake comprehensive treatment works. The construction sites are in different banners and counties. The works not only includes reclaimed water treatment facilities and wastewater treatment reuse facilities, but also includes pipelines of rainwater, wastewater and reclaimed water, water fetching and supply pump stations, and excavation of Wuliangsuhai Lake grid and artificial wetland construction. Therefore, there are many constructors from all corners of the land and the mobility is strong. Because the construction places and construction sites of all works are not centralized. Living and sanitary conditions are poor and labor intensity is strong, and therefore diseases may be easily transmitted. In order to guarantee the construction safety, complete physical examination shall be carried out for all constructors. Constructors with infectious diseases are prohibited to enter the construction site. Regular physical examination shall be carried out for the personnel in canteen of all works. If the personnel has the infectious disease, the personnel shall be promptly cured and not work in the canteen to prevent the disease transmission. The centralized water supply facilities shall be equipped in each construction site. The water source shall be sterilized and monitored. The construction site shall be provided with the medical facilities. Labor protection measures shall be carried out for constructors to protect their health and safety so as to make the construction smooth.

5.2 Environmental Impact Analysis of Operation Period 5.2.1 Reclaimed Water Supply Works 5.2.1.1 Reclaimed water treating process and pollution factors analysis Treating processes of reclaimed water supply projects are different because of water quality of their sources. Except for the project of Wulatehouqi County Manufacture Park where raw water is only treated by disinfection, the other projects add relative process units like the pre-aeration tank and the RO workshop based on conventional treatment such as coagulation, sedimentation and filtration to guarantee quality of reclaimed water. Refer to Fig. 5.2-1 for treating process of reclaimed water and discharge nodes. Main positions generating and discharging pollutants during operation of the project� (1) Waste gas Waste gases of the reclaimed water supply project are chlorine dioxide G1 leaked from the chlorine dioxide generator that runs with fault; and fugitive emission odor G2 from the sludge pump house, the sludge thickener, sludge dewaterer house and the sludge yard; In addition, the plant with pre-aeration process includes odor gas G3 from the pre-aeration unit. (2) Waste water Waste water of the planned project during operation comes from the reaction sedimentation tank for sludge thickening W1, filter backwashing W2, sludge dewatering and filter pressing W3 and wastewater, containing main pollutants such as SS, CODcr and BOD5. Otherwise, the plants with RO process also include brine W4. (3) Solid waste Sludge S1 is generated by the flocculating tank, sedimentation, filtration sand cylinder, automatic valveless gravity filter and so on. Furthermore, a little domestic garbage. (4) Noise Noise comes from the intake pump house N1, intermediate lift pump house N2, back wash pump house N3, blower house N4, sludge pump house N5 and sludge dewaterer house N6. 5.2.1.2 Pollution source analysis for the project According to intake water quality of the project, dosage, and the principle of material balance, confirm pollution source intensity of each engineering. (1) Waste gas pollution source intensity H2S and NH3 are used as the characteristic pollutants of waste gas for environmental assessment of odor from the plant. The analogy method is used to determine fugitive emission odor pollution source intensity of each engineering, odor emission coefficient of each treating unit can be characterized by emission in unit duration and on unit area. Based on data of Tianjin Jizhuangzi WWTP, Hangzhou Sipu WWTP and Stage I of Shenzhen Baoan Gushu WWTP, determine odorant emission coefficient of each plant in this project, refer to Table 5.2-1. Waste gas source intensity can be estimated according to surface area of designed structures. The feasibility study report does not provide any deodorizing measures, so the bio-deodorization method is recommended to treat main odor pollution source. Refer to Table 5.2-2 for generation of odor pollution source and emission intensity of each plant.

(2) Water pollution source intensity Tail water of each reclaimed water plant (sludge water) mainly comes from the sedimentation. For sustainable development of water resource, the measures of waste water recovery is adopted at the clean water plant, sludge from the flocculation sedimentation is thickened at the thickener, supernatant flows to the front end distribution well for recovery; at the same time, waste water from sludge press filtration returns to the front end distribution well, which may not only reduce water consumption in the plant, but also mitigate pollution to environment around by the plant for no production waste water drain. Because SS is the main pollutant in waste water from supernatant of the thickener and sludge dewatering, which is smaller to compare with total water quantity of the plant, no impact to outlet water quality, it is available for reusing. According to the principle of material balance and analogy among similar enterprises, refer to Table 5.2-3 for waste water quantity and water quality of reaction sedimentation tank for sludge thickening waste water�filter backwashing waste water and sludge dewatering waste water. Wastewater from the planned project is calculated as 150L per capita, wastewater discharge percentage is 80%. Refer to Table5.2-3 for details of producing and discharge.

(4) Solid waste In order to protect surface water bodies and use water resource reasonably, it is necessary to separate solid and liquid of sludge water during operation of the plant. Sludge water drained from the sedimentation should be collected in the balancing tank, and then transport sludge after thickening and dewatering. Filter back wash waste water is drained to the waste water tank and lifted to the front end for reusing by the pump. Solid waste from each plant of the project is mainly sludge after thickening and dewatering and domestic garbage. Sludge quantity of the reclaimed water project is calculated according to SS concentration of inlet water and consumption of flocculant. Sludge is treated by centrifugal dewatering with water content 75%. Since there is no hazard chemicals, no poison, which may be used as cover soil of landfills, backfill soil of municipal road construction and brickmaking. While domestic garbage from the reclaimed water supply projects is calculated as 1.16kg/d·person, which should be collected and delivered to the environmental sanitation administrations. Refer to Table 5.2-5 for solid waste of each reclaimed water supply project. Table 5.2-5 Solid waste of each reclaimed water supply project

5.2.1.3 The environmental impact analysis of regenerated water project project 1� Environmental Impact Analysis of Surface Water The effluent discharge of the reclaimed water supply works are consist of sedimentation tank muddy water, back flushing water of filter tank, filter-pressing waste water of sludge and domestic wastewater. In addition, the effluent discharge of Ganqimaodu port processing park and No. 7 Drainage Canal reclaimed water supply works also include ultra-filtration reverse osmosis tail water because of reverse osmosis workshop. y� The muddy water from sedimentation tank and back flushing water from filter tank of the

reclaimed water supply works are discharged into plant sludge pool for sedimentation concentration, dewatered by the filter press in dewatering room and carried out in form of mud cake, leaving the supernatant solution back flow into flocculating setting tank along with new water for treatment. The filter-pressed waste water from dewatered room makes back-flow into front distribution well along with new water for treatment after settlement.

y� The tail water from ultra filtration and reverse osmosis process in reclaimed water supply works in Wulatehouqi County Processing Park, No. 3 and 7 Drainage Canals and Ganqimaodu port processing park reclaimed water supply works are all treated by coagulating sedimentation and then piped into front distribution well along with new water for restoration process, leaving the waste water un-discharged.

y� The domestic water of this reclaimed water supply works is treated with different methods and ways based on the surrounding infrastructure conditions. The domestic water from Wulatehouqi County processing park reclaimed water supply works will be diverted to its wastewater treatment works for treatment and that of No. 3 and 7 Drainage Canals are diverted to their corresponding Hangjin Rear Banner and Wuyuan County Wastewater Treatment Plants, leaving that of Ganqimaodu Port to be treated by the plant ground-embedded biochemical treatment equipment in accordance with the requirements of The Reuse of Urban Recycling Water.—Water Quality Standard for Miscellaneous Water Consumption (GB/T18920-2002)without drainage.

Therefore, this project has no effluent discharge making no impact on the surface water environment. 2� Environmental Impact Analysis of Waste Gas The reclaimed water supply works will not bear any odor, yet, produce slight odor in the sludge tank, thickener tank and sludge thickening dewatering room. In addition, the reclaimed water supply works of pr-eaeration unit also produces odor. Since the water source of this reclaimed water supply works are inevitable in bringing slight pollution of water. Therefore, the odor is too slight to making environmental hazard. And since the sludge treatment area of this reclaimed water supply works is equally distributed at the down-wind direction of water treatment plant along with green isolated area to separate production and living areas, therefore, waste gas will not have any impact on the plant production and living. 3� Acoustic Environmental Impact Assessment According to the property and environmental characteristics of sound, the corresponding computation schema shall be used to calculate the sound level of sound source for future position. Efforts shall be also made to estimate the acoustic environmental impact of the project after completion. (1)Acoustic Environment Quality Forecast Mode The forecast mode selected based on requirements of acoustic environment assessment guide rules shall be simplified according to concrete conditions. � Octave band pressure level of outdoor point sound source for future position

If untreated properly, the secondary pollution may be caused.

The gravity thickening mechanical dewatering process is used for the reclaimed water supply process according to the property of sludge, which may conduct decrement of sludge, reduction of water content and reduction of sludge volume for the convenience of transportation and treatment. The treated sludge may be comprehensively used, such as sandy landfill mulching soil, backfill or brick making of road of city planning and sanitary landfill based on the physical circumstances. In addition, the sludge treatment area is located at the downwind direction of plant, which is far from living area and hardly to bring any adverse effect on plant production and living. The domestic garbage will be timely and effectively handled by environmental sanitary division without causing secondary pollution. According to the analytic result of solid waste of this project for environmental impact, following measures are suggested to remove or reduce the impact: y� During plant piling and out-transportation, the sludge shall be timely and effectively handled to

reduce its contact with environment and avoid any pollution on surrounding environment. y� The dewatered sludge shall use partially closed tipper for out-transportation in case of sprinkling

and secondary pollution. y� The domestic garbage shall be timely cleaned and handled in case of secondary pollution. 5�Impacts on Water Resources The water sources of the reclaimed water supply works are consist of wastewater treatment plant effluent, drainage ditch drainage and underground water. See table 5.2-7 for the water source and consumption of reclaimed water supply works. Table 5.2-7 Water Source and Intaking Amount of Reclaimed Water Supply Works

The water intaking amount of this project of reclaimed water supply works using effluent of wastewater treatment plants as source is 15.797 million m3/a, which will not only save a great amount of water resources, improve the utilization but reduce emission of pollutants. The water intaking amount of Wulatehouqi County and Ganqimaodu port processing park reclaimed water supply works from the main drainage ditch is 26.65 million m3/a and that of No. 3 and 7 reclaimed water supply works from No. 3 and 7 drainage ditches are 512.4 and 48.312 million m3/a. The water intaking amount of reclaimed water supply works in winter is 7.1018 million m3/a.

According to the research report on the reasonable allocation of Bayannaoer City water resources, the available water resources of Bayannaoer in normal years is 6.23 billion m3, among which the normal average annual water taking from Yellow River is 5.2 billion m3, the degree of mineralization of industrial, agricultural and urban populous area is 2g/l and exportable groundwater is 0.85 billion m3. In 2002, the practical exportable groundwater for industrial and agricultural purposes reached 0.58 billion m3. In 2003, because of water shortage of Yellow River and fighting for drought, the production volume in Hetao Area and along-mountain region was 0.78 billion m3, which was very close to the available volume. Some areas have become overdraft hopper zone. By 2010, except over-intaking water from Yellow River for agriculture, the ecological water shortage is 0.303 billion m3. And the demand of underground water will increase to 1.118 million m3 from 0.58 million m3. The gap of underground water with mineralization less than 2g/l will reach 0.268 billion m3. The gap will also reach 35 million m3 even using the water with mineralization between 2-5g/l. The water shortage problem will be the principal contradiction that restricts the economic and social development of Bayannaoer city. Therefore, the implementation of this project may reduce a groundwater exploitation of 52.4022 million m3 protecting underground water, releasing the shortage of water resources and promoting the economic and social development of Bayannaoer. 5.2.2 Wastewater treatment and recycling engineering in Processing Park 5.2.2.1 Analysis of waste water treatment and reclaimed processing and pollution factors The secondary waste water treatment processing in each waste water treatment and reclamation project adopts A/A/0, and reclaimed water treatment processing adopts coagulation – sedimentation – filtration. Refer to Fig. 3.2-3 for waste water treatment and reclamation processing. Pollution factors during construction and operation of the waste water treatment and reclamation project is similar with the reclaimed water supply project, refer to Section5.2.1.1� 5.2.2.2 Pollution source analysis of the waste water treatment and reclamation project (1) Odor pollution source During operating of the WWTP, odor pollutants are generated by metabolism of organism such as the microorganism, protozoan and zoogloea, main compositions are H2S and NH3, the main emission sources are the grille house, the water intake pump house, the rotational flow grit chamber, bio-reaction tank and sludge treatment structures. The bio-deodorization method is recommended for each waste water treatment and reclamation engineering in this project, which may collect and exhaust odor from the grille house, the intake water house, the rotational flow grit chamber and the sludge treatment structures, in this evaluation, it is considered as the point source. Because the bio-reaction tank of each WWTP has large area and large air quantity during aeration, odor is hard to collection, it is considered as the area source in this evaluation. Since there is no systematic public data for estimation odor output of a WWTP in China, the analogy method is used to determine odor source intensity here.

Point source intensity Shanghai Longhua WWTP has similar waste water source with this project, where CAST bio-treatment processing is used with actual treatment quantity of 80, 000t/d.

Shanghai Environmental Science Institute measured strongest odor sources of Hualong WWTP in 2002-2004 for many times, for example the sludge thickener, the sludge yard and the grille well. Refer to Table 5.2-8 for the results of odor monitoring.

Table 5.2-8 Odor source intensity monitoring results at Longhua WWTP

Max. 5.98 0.134 NH3 (mg/m3) Average 3.01 0.108

Since odor emission of WWTPs is not stable, which depends on many factors such as climate and weather conditions. In view of conservative engineering, the Max. monitoring values are used for analogy in this environmental assessment, refer to Table 5.2-9 for odor source intensity of each WWTP.

Odor from pollution sources of each WWTP will be collected and sent to the bio-filter at the deodorization room and then exhausted through the exhaust mast. Efficiency of bio-deodorization is about 90%, design blower air delivery of each WWTP is 4500m3/h. After bio-deodorization, refer to Table 5.2-10 for odor exhaust rate of each WWTP.

(3) Solid wastes When the project starts operation, solid wastes mainly are the grille dreg, grit chamber sludge, excess sludge and domestic garbage. � Grille dreg and sand

Most fine grille dregs are blocky solid materials, including both inorganic and organic substances, like domestic garbage. Stop diameter of a fine grille is substances with diameter more than 6mm; while grit is inorganic particles, such as argillaceous silt and carpolite. The rotational flow grit chamber removes oily substances and sand particles with specific gravity more than 2.65 and grain size more than 0.22mm mainly. According to Code of outdoor drainage design, grit quantity of urban waste water can be calculated as 0.03kg/m3, while quantity of grille dreg can be calculated as 0.1 kg/m3, refer to Table 3.3-12 for the output. Treatment of dreg and grit is performed by the grille machine, the belt conveyor, and the presser, which may avoid odor emission and vermination. After treatment, they can be landfilled as urban garbage.

� Sludge Excess sludge in the sludge tank will be lifted to the combined thickening and dewatering machine with 0.5% high molecular organic flocculant PAM. Water content of sludge after dewatering should be less than 80%, refer to Table 3.3-12 for dewatering sludge quantity.

� Domestic garbage

According to the Stat. data of Bayannaoer garbage station, average garbage output per day per capita is about 0.8kg/d, it is reduced by half for employees. So garbage quantity can be calculation by employees during operation of each plant. Refer to Table 3.3-12 for details. By calculation, refer to Table 5.2-14 for solid waste output of each waste water treatment and reclamation plant.

5.2.2.3 The environmental impact analysis of wastewater treatment project 1�Prediction and Analysis of malodor Environmental Effect (1) Pollutant concentration prediction The evaluation is to predict pollutant concentration, taking Wastewater treatment and recycling plant in Processing Park in Wulateqianqi County as an example. Pollutant concentrations in the other two plants is the same or lower than this wastewater treatment plant, so the prediction can be analyzed as a reference for the other 2 plants. According to the prediction of pollutant sources of NH3 and H2S in the previous section, SCREEN estimation model, recommended by Technical Guidelines for Environmental Impact Assessment Atmospheric Environment (HJ2.2-2008), is adopted to predict the sphere of influence of discharge concentration. Point source and point source prediction results are shown in Table 5.2-16 and 5.2-17. Table 5.2-16 predictions under point source estimation model

The largest area source concentration of NH3 and H2S is 0.011g/m3 0.001mg/m3, accounting for 5.5% and 10% of the maximum allowable emission of harmful substances in atmosphere in " health standards Industrial Enterprises Design " (TJ36-1979 ). In Totalmary, the concentration of NH3 and H2S emissions of the wastewater treatment plants is low, thus have little influence on the surrounding atmosphere. (2) Health protection distance According to "Municipal Wastewater Treatment Plant Pollutant Emission Standards" (GB18918-2002), the new site (including reform, expansion) of urban Wastewater treatment plant should be consistent with the overall planning requirements of local urban and rural construction. Green belt should be built around urban wastewater treatment plants, and certain protective distance should be kept, the size of which is determined by the environmental impact assessment. The evaluation is to calculate the Health Protection distance based on the example of wastewater treatment plant in Wulateqianqi County. The scale of pollution Source of the other two plants is the same, so the health protection distance is applied accordingly. The calculation method, which is about unorganized harmful gas emissions of health protection distance given in" local technical methods of air pollutant emission standards (GB/T3840-91) ", is adopted, and it is as follows:

S 800 A �B�C�D A=350�B=0.021�C=1.85�D=0.84 According to the prediction, health protection distance of NH3 and H2S is calculated as 15m and 35m. According to the relevant provisions of technical methods of development of local air pollution emission standard (GB/T3840-91), health protection distance of the wastewater treatment plant is 50m. All the wastewater treatment plant sites selected in the project are 500m away from residents, so the impact of the project on the surrounding residents is within the permission of the state. According to forecasts and integrated analysis of analog, the project has little effect on the regional air environment and will not have a significant impact on the neighborhood. 2� Water environment impact analysis (1) Surface water environment impact analysis The water process link of various wastewater treatment and reclaimed wateris water sedimentation, sludge thickening, filter backwash water and cleaning life water and water for equipment. The wastewater of this part goes from the wastewater pipes in the plant and then will be collected and processed in the wastewater treatment without discharging and have no impact on surface water. In addition, the scale of wastewater treatment and water recycling project in Ganqimaodu Port processing park is 30,000 m3 / d, the scale of renewable water treatment is 2.4 m3/ d, and the remaining 6,000 m3 / d water discharge into the main channel as a landscape of water; Wulateqianqi County wastewater treatment and reuse of the wastewater capacity is 30,000 m3 / d, and the scale of renewable water treatment is 2 m3 / d, and the remaining 10,000 m3/ d water discharge into the fourth channel as a landscape. The above two wastewater treatment plants is implemented according to standard A of "Municipal Wastewater Treatment Plant Pollutant Emission Standards," and also meet the need of landscape water requirements. It will not be drained totally and has little impact on the water quality of the fourth channel. The treated wastewater of Wulatehouqi County Processing Park goes into wastewater treatment plants of Wulatehouqi County to be recycled without discharging. Meanwhile, due to the wastewater treatment and the construction project of regenerated water cycling, it enhances the industrial wastewater treatment, increases water reuse rate, reduce pollutants load from processing parks effectively and decrease the quantity of pollutant discharged into rivers and benefit water quality improvement in the project area. After the project of wastewater treatment and recycling is completed, according to wastewater treatment capacity of 80,000 m3/ d, reuse water of 64 000 t / d, it can save water 22.63 million m3/ a, reduce water pollutants CODcr 14271t / a, BOD8694t / a, ammonia 697t / a. It is of great importance to reduce regional water pollutants discharge load. In Totalmary, after the project of the wastewater treatment and reclaimed water reuse project is completed and operated, it can effectively reduce the regional emissions, and can promote regional water environment with little impact on surface water bodies. (2) Analysis of groundwater environmental impact After the completion and operation of wastewater treatment plants, domestic wastewater and industrial wastewater of all processing parks will be discharged into the wastewater treatment plant. The construction of pipe network collection and harmless treatment of wastewater reduces the bad effect of water infiltration on underground water pollution in processing parks. Therefore, the implementation of the project has a positive influence on regional groundwater environment. However, in the course of operation of the project, strict measures should be taken to prevent leakage of wastewater pipes and wastewater treatment facilities and avoid leachate into the groundwater in the course of dumping sludge. Seepage coefficient is less than 10-7 cm / s, the sludge generated by the project will be removed periodically, and sludge-dumping ground will be seepage proofing to ensure the effective protection of groundwater sources. 3� Acoustic Environmental Impact Prediction and Analysis (1) Prediction model In accordance with HJ/T2.3-95 “environmental impact assessment technology guidance Acoustic Environment”, the noise source is regarded as a state of semi-free point source. It is tested in noise source coordinate system and floor plan to identify noise sources position, forecast positions, the distance between forecast position and sound source according to forecasts point. Equivalent sound

level of sound pressure at any point LeqdB (A) is calculated with accordance of air attenuation model of acoustic energy in the environment. 1 the effect of single point sound source on predicted position, the mode of calculation is as follows:

LA (r) = LA (r0)-20lg (r/r0) The formula: LA (r) - sound level value from sound source r, dB (A); LA (r0) - sound level value from reference position r0, dB (A); r - distance between predicted point and sound source, m; distance between reference position and sound source, 1m.

2 noise sound level of more than one sound source to a certain predicted position on the T-time, the mode of calculation is as follows: The formula: Leq (T) - the total sound level of predicted position, dB (A); n - the number of outdoor sound source.

(2) Environmental noise prediction of wastewater treatment plant

Judged from the distribution of noise source, noise source are all in the plant. Blowers and all kinds of pumps are fixed in a separate device room, and the after the room acoustic shielding, green noise and distance attenuation effects, noise made by the equipment can be attenuated. Noise prediction results of various projects can be seen in Table 5.2-20. Table 5.2-20 Noise Prediction of Wastewater Treatment Plant and surrounding Area

According to the above table, noise at plant boundary of the wastewater treatment plants confirm to three functional areas standard criteria of daytime and night: 65dB (A ) and 55dB (A) provided by “Industrial enterprises plant boundary noise emission standard” (GB12348-2008). Moreover, no people live within 500 meters around the wastewater treatment plants and there is little noise impact on the surrounding environment. 4� Analysis of Solid Waste Environmental Impact (1) Impact of sludge dewatering process on the environment Before dewatered, generally speaking, sludge should be concentrated. Concentration tank often exudes stench, especially in the hot Totalmer months, there are floating mud on the pool surface, and it is easy to infest mosquitoes. When concentrated sludge is dewatered, the dewatering room will emit foul smell; in case of spilling in the process of dewatering sludge, environment will be polluted. (2) Impact of sludge dumping on the environment Dewatered sludge should be timely removed. The sludge, which cannot be transported in time, should be put in temporary stacking areas. Dewatered sludge is easy to turn into slurry with water, which is of good fluidity and wash away easily; when it rains, water integrates with a large number of pollutants,

polluting surface and groundwater. Therefore, the dehydrated sludge can not be cluttered, but should be treated with the impermeable layer of the temporary dumping place specially, and then stamp rain-shelter; In addition, the dehydrated sludge is not completely stable, long-term stacking will produce sludge anaerobic digestion. H2S odor produced by such substances will affect air quality; dehydrated sludge stack place is the breeding ground for mosquitoes, and have an undesirable effect on environmental health. For these reasons, sludge should be removed after dewatering time to avoid piling up in the factory. (3) Impact of sludge transportation on the environment Although the sludge in the plant have been treated to various extend, the sludge still has some harmful pollutants. The sludge of the project in various wastewater treatment plant is only concentrated and dehydrated and fail to meet the requirement of sludge stabilization and harmless condition. The sludge contains large amounts of perishable organic matter and coli, ascaris eggs and other pathogens microorganisms. Therefore, transportation process of sludge is a very important environmental issue. At present, the main transportation of sludge is trucks. If the sludge hangs on the body and wheels of trucks in the handling process, or the vehicles are poor sealed, the trucks will spill sludge around wastewater treatment plant and along the road, which cause pollution along the road. Muddy water flowing and malodorous spreading should be prevented in the process of sludge transportation. Wastewater Treatment Plant should use special closed vehicles to prevent water leakage, mud leakage and scattering. Meanwhile, the sludge transportation time should be strictly controlled, trying to avoid heavy traffic times. In short, the sludge transportation is a very important problem to be taken seriously. (4) Sludge treatment program of wastewater treatment plant Sludge is the product of the wastewater process and it is an important component of the wastewater treatment. Sludge treatment aims to decrease the sludge moisture content and sludge volume to stabilize its nature and then create conditions for further disposal and comprehensive utilization. The general process includes “concentration - Dewatering –Disposal” or “concentration- digestion - Dewatering – Disposal”. According to feasibility study report, due to biological nutrient removal technology adopted by the wastewater treatment, sludge age is a little longer and the sludge is relatively stable, so there is no need to carry out nitrification. In the case of nitrification, a digestion pool, heating, stirring and a series of gas treatment and utilization structures and equipment are needed while investment increases. However, land area in the wastewater treatment park is limited, so sludge nitrification system cannot be built. According to analog data, sludge components of the wastewater treatment plant relate with water quality of wastewater. Generally, excess sludge of industrial waste water in wastewater treatment plant contain high amount of heavy metals, far beyond the agricultural sludge standard, therefore it should be safely landfill ed instead of being used as agricultural fertilizer. 5�Ecological environmental impact analysis (1) Land use and soil restoration Since the original crops, natural vegetation are replaced by various types of buildings, roads, green belt and other land. The function of land-use changes greatly. After completion of the project, discarded soil can be reused to build green belt of the plant. At the same time, ground hardening and green belt building can hold the soil, reduce soil erosion; and it can also be used to cover soil in reuse landfill. (2) Vegetation cover After completion, the plant’s green area with trees on both sides of the road, the total green vegetation coverage rate will be higher than before. It keeps soil and water as well as beautifies the environment. The greening rates of all projects are seen in Table 5.2-21. Table 5.2-21 Green rates of the projects

(3) Landscape Ecological Analysis Before project construction, landscape patterns are simple, the degree of connectivity is poor, and the degree of heterogeneity is low. After completion of the project, there are various types of buildings, roads, green belt, and other kinds of combination. As there are more tree species, species diversity increased, correspondingly landscape heterogeneity increases. However, trees introduced by manual work require a certain process of selection and adaptation to the environment. When the project has just completed, the variability of trees is large and anti-interference ability is poor, but all of these will greatly improve over time. 5.2.3 Wuliangsuhai Lake Lake Administration Project 5.2.3.1 Pollution factor analysis of Wuliangsuhai Lake area comprehensive treatment Pollution factors during operation are mainly from operation of the Wuliangsuhai Lake artificial wetland. (1) Noise Noise mainly comes from the artificial wetland pump station with noise source intensity 80dB(A). (2) Solid waste Main solid wastes during operation of the artificial wetland are sludge in the sedimentation pond, which will be dredged about every 7-10 years, transporting outside to avoid secondary pollution. 5.2.3.2 Pollution source and main pollutants discharge analysis Refer to Chapter 5 of this report for pollution sources and pollutants discharge during construction of the project of Wuliangsuhai Lake area comprehensive treatment. Main environmental impact during operation of the project of Wuliangsuhai Lake area comprehensive treatment is pollution source discharge of Wuliangsuhai Lake area artificial wetland. 1) Noise Noise during operation comes from the pump station and the aeration pond mainly. Refer to Table 3.3-14 for noise source intensity. 2) Solid wastes Solid waste during operation of the artificial wetland is mainly sludge in the sedimentation pond, which will be dredged about every 7-10 years; in addition, people for management and maintenance of the wetland will produce domestic garbage. 3) Pollution source intensity analysis Refer to Table 3.3-14 for producing and estimated discharge of main pollutants of the project of Wuliangsuhai Lake area comprehensive treatment.

5.2.3.3 Analysis on Environmental Impact of Wuliangsuhai Lake Treatment Works The project, ecological works with no pollution features no permanent constructions in existence or operation during its operation period. The unfavorable environmental impacts in the operation period of the project mainly include the waste gas and noises of artificial wetland in operation and the change of partial water circulation system and can be effectively alleviated in adoption of proper measures; and favorable environmental impacts of the project in the operation period mainly include the cut-off of the pollutants in the lake and the improvement of the quality of water of Wuliangsuhai Lake flowing into the sea and ecological landscape pattern of Wuliangsuhai Lake valley and sea area waterway system. 1�Analysis on Adverse Environmental Impact of Wuliangsuhai Lake Sea Area Treatment Works (1) Impact on Atmospheric Environment The proposed project emissions are mainly produced by microbial decomposition of CO2, as well as stench of decaying animal and plant and other microbial life. The quantity is small, and the concentration produced can reach the maximum allowable concentration of secondary standards given by “municipal wastewater treatment plant emission standards” (GB18918-2002) factory sector. (2) Noise Noise generated by the project is mainly from mechanical noise made by pumping equipment. Source intensity noise value is about 80dB (A). By status monitoring and predicting (predicting model: use HJ/T2.4-1995 “Environmental Impact Assessment Technical Guide: sound environment” indoor point source model and outdoor plane source model are recommended), Sound Pressure Level prediction of different distance pumping equipment is shown in table 5.2-23� Table 5.2-23 List of sound pressure level projections at different distance of running pumping equipment Distance (m) 100 200 300 400 500 600 700 800 900 1000 1050 Noise value dB (A) 66.7 61.3 58.3 56.3 54.8 53.6 52.6 51.7 50.9 50.3 50 As it can be seen from Table 5.2-23, due to using pump in operating period, noise value is high, the impact is strong, and some has long duration and accompanied by a strong shock. Since the core construction area is 5-10 km from the nature reserve area, it will not affect birds nesting, foraging, courtship and incubation of birds of national-level protection. (3) Changes in the local water cycle After the completion of the proposed project, wetlands treatment system will have certain impact on groundwater environment, water balance is seen in the following table 5.2-1.

5.2-1 Wuliangsuhai Lake water balance According to the soil permeability, the annual infiltration of water of the proposed project is 1.518 million m3, which is a supplement of groundwater. The raising of water level may cause groundwater level rise of surrounding farmland, while infiltration and penetration will lead to soil salinization, affecting the normal cultivation of farmland, so outside of wetland reed field is treated by vertically burying plastic technology to prevent leakage. 2�Analysis on Positive Environmental Impact of Wuliangsuhai Lake Treatment Works (1) Reduction of Pollutants in the Lake The pollution load reduction by ther Wuliangsuhai Lake biological transition zone artificial wetland project is shown in Table 5.2-24. As the ice is not stable, microbial effect is weak, and removal efficiency will be greatly reduced, but it reduces pollution load of ice to a certain extent, and it plays an important role in reduction of the total pollution load into the lake. After the project’s completion, the trend of serious pollution of Wuliangsuhai Lake will be initially alleviated, and quality of water flowing back into Yellow River from Wuliangsuhai Lake will be improved.

After wetland ecotone is completed, water quality of non-frozen season can reach Grade � standard (on average) of national “Surface Water Environmental Quality Standard GB3838-2002” predicted by the model, that is, the concentration of pollutants in water status can be reduced to CODCr 30mg / l, TP 1.5mg / l and TP 0.1mg / l. (2) Improvement of flow field in Wuliangsuhai Lake Simulation analysis adopts one-dimensional river model (MIKE11) two-dimensional lake model (MIKE21) and one-dimensional and two-dimensional coupled hydrodynamic and water quality model (MIKE FLOOD) developed by Danish Hydraulic Institute. Simulation analysis of flow and lake water quality adopts two-dimensional hydrodynamic model MIKE21 and sea waterways grid design adopts MIKE FLOOD. Wuliangsuhai Lake flow field change before and after construction is shown in Figure 5.2-3.

(a)no canal design; (b) drainage canal design; (c) drainage canal + branch canal design Figure 5.2-3 Lakes flow field simulation results (no wind in Totalmer) y� It can be seen from the simulation graph: compared with the current flow field situation,

implementation of the project improves flow field of the reservoir area obviously. Stagnant water areas of East Beach and other large areas of water are eliminated. In the case of no wind, stagnant water area is reduced by about 30-40 km2;

y� Flow rate of southern main Lake District increases slightly after implementation of the canal dredging extension. It has a little effect on flow condition of northern and western lake. overall improvement of the lake is limited;

y� In reed field of Lake District, the mainstream flow field becomes more smooth and overall flow pattern of the Lake improves greatly, as channels are connected, main canal and branch canal are excavated, and water stagnation area is reduced by more than 10 km2.

(3) Improvement of Water Quality of Wuliangsuhai Lake by Treatment Works Wetland water quality concentration of inlet and outlet in non-frozen season and frozen season is shown in Table 5.2-28. The simulation pictures of 5.2-4 and 5.2-5show water quality of two seasons.

From prediction of lake water quality, the following conclusion can be made. (Table 5.2-29): y� Compared with status quo program, COD concentration in the lake greatly improves. Water area of

Inferior Grade V decreases by about 121 km2 in frozen season. COD concentration greatly reduces in non-frozen season. Inferior Grade V area is basically eliminated in the whole lake water. Water area of Grade V is 100-128 km2, water area of Grade IV is 86-97 km2, and water area of Grade III is 26-39 km2.

y� Compared with status quo program, TN of the lake improves. In frozen season, water area of inferior Grade V decreases by about 25-41 km2, and water area of Grade IV increases by 28-49 km2. In non-freezing season, TN is significantly improved while water area of inferior Grade V decreases by 101-121 km2.

y� Compared with status quo program, TP of the lake improves, and in frozen season water area of above Class III increases by 18-54 km2. In non-frozen season, TP improves significantly; water area of below Grade V is eliminated in the whole lake, and water area of above Class III increases by 90-110 km2.

The followings can be known from water quality prediction results: y� Compared with thecondition prior to the project, in non-frozen season, outlet COD concentration of

the program falls down to 31.77 mg / L with a decrease of 7.96 mg / L, and is equal to Grade V of water quality. In frozen season, it falls down 12.53 mg / L, and the overall water quality improves and reaches Grade IV of water quality stably.

y� Compared with the status quo, in non-frozen season, TN concentration of water outlet of the program falls by 0.85 mg / L, maintaining Grade V of water quality, and the overall of water quality improves a grade. In frozen season, it declines about 0.43 mg / L and reaches Grade IV of water quality stably.

y� Compared with the status quo, in non-frozen season, water outlet TP concentration of the program falls 8 ug / L, maintaining Grade II of water quality, and water quality improves. In frozen season it falls down 3 ug / L, remaining Grade I of water quality;

(4) Ecological landscape pattern analysis of Lake District channel system Landscape spatial pattern is arrangement of landscape patches of different sizes and shapes in space, and it is an important manifestation of landscape heterogeneity. Meanwhile it is also the result of a variety of ecological processes at different scales. Landscape spatial pattern analysis of wetland landscape is significant to the wetland landscape study of spreading species, flowing energy and transporting material.

Based on latest topography data of Wuliangsuhai Lake(2009), supported by GIS spatial analysis function, we analyze landscape pattern status of Wuliangsuhai Lake, landscape change after channel excavation and its ecological impacts. Since the excavation of Wuliangsuhai Lake waterways (especially the newly added waterway) may interfere with Wuliangsuhai Lake landscape pattern, and then may lead to a series of ecological problems. Therefore, focus should be placed on landscape pattern changes before and after channel excavation. � Technical methods

According to the latest topographic maps of Wuliangsuhai Lake, landscape distribution vector diagram is got by coordinate registering, digitization in mapinfo 7.5, as is shown in Figure 5.2-6. By using geographic information system software Arcgis 9.0, vector files are analyzed in term of topology and spatial database of various landscape types and its associated attribute database are generated. All polygons corresponding with landscape type are assigned certain property values, generating basic database, which is needed to meet the characteristic indicators for calculation. Based on Arcgis 9.0 platform, the Spatial Analysis extension transforms vector diagram into raster charts, and then it uses analysis software Fragstats3.3 of landscape pattern to compute the landscape metrics.

Left: before excavation; right: after excavation Table 5.2-6 Lake district landscape pattern chart of Wuliangsuhai Lake �Ecological landscape pattern analysis of channel excavation

a. Landscape analysis of type Calculated by Fragstats software, the main types of landscape indices (class metrics) (Table 5.2-31) are obtained. Analysis of the landscape index shows that: y� Reed land and open water, two types of landscape, take up 54.9% and 45.1% respectively.

After channel excavation, open water will increase by 0.7%, while reed land will decrease slightly.

y� After waterway excavation, some waterways will be split by reed land, and the number of reed land plaque will increase to 40 from the present 25 and the maximum plaque index will drop from 7 to 5.8; the open water connects through watercourse, and the number of plaques reduces significantly, and the largest patch index rise to 45.8 from 45.1. It is beneficial to maintain the integrity of the ecosystem and reduce swamp formation due to expansion of the reed.

y� Through the newly added branch waterways, both numbers of Total Edges and Edge Density of reed land and open water landscape have significantly increased, indicating the effect increased obviously. It is beneficial to material exchange, energy flow, purifying the entire water in Lake District, and increase habitat diversity in Wuliangsuhai Lake.

y� Landscape shape index refers to shape index of perimeter and reflects the complexity of patch boundaries. After channel excavation, two types of landscape shape index and average fractal dimension increases significantly, especially the status quo value of 3.45, the average fractal dimension value of open water, will raise to 7.7, increasing the acting surface and acting time of lake and reed land. It is favorable to help water purification.

y� Plaques contiguity index (contiguity index), clumpy index (CLUMPY), plaque cohesion degree (COHESION), division (DIVISION), and degree of polymerization (AI) calculations show that the two kinds of reed land and open water landscape have high degree of connection and low degree of fragmentation. Compared with the status quo landscape pattern, landscape indices after waterway excavation will not change significantly. It is indicated that although waterway excavation splits part of the reed land, the internal space pattern of two types of landscape does not change greatly.

Table 5.2-31 landscape index of type

b.Pattern analysis of landscape standard

Analyze landscape pattern change of Wuliangsuhai Lake before and after excavation from the view of landscape standard. Landscape index can be seen in Table 5.2-32, and the analysis shows: y� The number of landscape plaque of status quo is 33, and the number of plaques increases to 43 after

excavation, which mainly results in waterways’ splitting of reed land. Accordingly plaque density rises from 0.13 / km2 to 0.17 / km2. Compared with other lakes of the similar area, the plaque density is higher. The number of total landscape edge rises from the current 47.8 to 55.5, which is beneficial to internal exchange of landscape material and energy flow. The increase of plaque number and edge number may have a negative effect on spatial distribution of reed. However, it is significant to slow down the swamp formation trend.

y� Sea district landscape shape index after waterway excavation was 8.41, which is significantly higher than the status quo of 7.25. It indicates that landscape complexity has increased significantly after excavation and it is beneficial to help increase habitat diversity.

y� Perimeter area of the score dimension is another measure of landscape shape index, and it mainly analyzes plaque type and the entire landscape fragmentation before and after channel excavation. Perimeter fractional landscape area of the score dimension (PAFRAC) is small, indicating landscape fragmentation of the entire sea area is of a low degree, and the overall integrity of the landscape will not be affected deeply.

y� Contag (CONTAG) and division (DIVISION) are used to characterize the degree of landscape fragmentation. Contag (CONTAG) of more than 50% shows a low degree of fragmentation and more large plaques; division (DIVISION) value is low and it shows that the distance between plaques is short. Currently landscape cantag of Wuliangsuhai Lake is more than 66% and division is 0.77. It indicates that sea district landscape type is relatively gathered and it has good connectivity and the degree of overall landscape fragmentation is relatively low. After channel excavation, landscape cantag will only decreased from 66.6% to 66.2%, and it will not affect the overall landscape greatly.

y� From the aspect of landscape diversity, landscape before and after the watercourse excavation has no significant difference, Shannon diversity index is 0.98-0.99, Simpson evenness index is 0.99, and it indicates high uniformity of landscape before and after excavation. However, landscape diversity is low. Largest plaque index increases slightly because the watercourse connects with the isolated watercourse.

�Impact of waterway system on ecological landscape pattern of Wuliangsuhai Lake

Fragstats (analysis particle size is 10 m) analyzes landscape type and index of landscape standard of ecological landscape systems in Wuliangsuhai Lake, and it makes analysis and evaluation of Wuliangsuhai Lake landscape from a quantitative and macro point of view. The results shows:

y� Open water area increases after channel excavation, forms habitat landscape type with open water and narrow channels to meet the habitat choice of different groups of waterfowl.

y� Although part of reed land is segmented by channel excavation, the number of plaques and edges increased significantly, landscape spatial pattern in Wuliangsuhai Lake (aggregation, connectivity, etc.) has not changed greatly, and it will not increase the degree of landscape fragmentation significantly.

y� After waterway excavation, the acting surface of reed land and open water surface increases significantly, which is beneficial to internal exchange of landscape material and energy flow in Wuliangsuhai Lake. It is also favorable to help water purification and increase biodiversity.

y� New added branch channel will split the local landscape. The increasing plaque density and edge density have a negative impact on the spatial expansion of reed, but it will help retard swamp formation of sea area.

2) Change of inlet water quantity after the completion of water recycling plant (1) Final drainage amount of general drainage canal Water recycling plant intakes water from general drainage canal, 3rd Drainage Canal and 7th Drainage Canal, and water of 3rd Drainage Canal and 7th Drainage Canal eventually flows into general drainage canal. Therefore, water quantity of water recycling plant subtracted from general drainage canal is eventually water quantity flowing into Wuliangsuhai Lake, as is shown in Figure 5.2-7. The water quantity is the total monthly amount of inlet water of manmade wetland with February as the month of the smallest amount of water of 4.892 million m3 and November as the month of the largest amount of water of 71.699 million m3. As is shown in Figure 5.2-8, after completion of water recycling plant, change rate of water draining into the Wuliangsuhai Lake is 4.7% -29.4% with January, February, March and April as the high water change months, respectively, 23.5%, 29.4%, 23.0% and 28.6%. It is mainly because these months fall on dry season with small amount of total drainage, while inlet water quantity of water recycling plant is stable. There is little change in other months.

Figure 5.2-7 monthly change of the total amount of water draining into Wuliangsuhai Lake before and after completion of water recycling plant (in the figure monthly mean quantity in 1996-2005 is given before the completion of water recycling plant )

Figure 5.2-8 monthly change of the total amount of water draining into Wuliangsuhai Lake before and after completion of water recycling plant 3) Effect of water recycling plant construction on Wuliangsuhai Lake ecological water demand In Wuliangsuhai Lake irrigation drainage has been regarded as ecological water supplement. until 2015 after the implementation of this project and taking water-saving measures, it is temporarily considered that agricultural water drainage will decrease by 10% , and drainage quantity of general drainage canal, drainage canal 8 and drainage canal 9 is 415 million m3 and 62 million m3 respectively. 31 million m3 of the total drainage into the wastewater has been recycled, and the water quantity of general drainage canal, drainage canal 8 and drainage canal 9 back into Wuliangsuhai Lake is 446 million m3. Four water Canels (Tarbes Canal, Changji Canal, Tongji Canal and Yihe Canal) inlet water from the Yellow River into Wuliangsuhai Lake in ice flood season, 44 million m³ of water is supplement water, and unchanged drainage of Wuliangsuhai Lake into the Yellow River is 154 million m3. Therefore, net water quantity into Wuliangsuhai Lake is 446 million m³. In order to maintain 515 million m³ of

ecological water in Wuliangsuhai Lake, 69 million m³ of water replenishment is needed from the four canals in ice flood season. According to Hetao irrigation district of Yellow River and Inner Mongolia anti-ice flood emergency flood diversion and preliminary design of Wuliangsuhai Lake flood diversion project, flood diversion volume is 161 million m3, of which Wuliangsuhai Lake takes up 100 million m3, and drainage canal in Hetao irrigation district and natural lakes in northern edge takes up 61 million m3. So flood diversion in ice flood season can guarantee supplement water of Wuliangsuhai Lake; the design has been approved by Water Resources Department of Inner Mongolia Autonomous Region ("approval of preliminary design about anti-ice emergency in Hetao irrigation district of Yellow River and Inner Mongolia and flood diversion of Wuliangsuhai Lake (internal water construction and management�2009�No.170). During ice flood season four canal drainage does not take indicators of inletting water from the Yellow River. It is taken as ecological water supplement of Wuliangsuhai Lake, in accordance with relevant national and local provisions.

According to data in the table, reduction amount through biological transition zone and manmade wetland treatment are CODcr 7405.38 t / a, TN 1327.86 t / a, and TP192.14 t /a. In summary, after the project is completed, it is expected that the pollution load reduction into the Wuliangsuhai Lake afte the project is completed is, CODcr will be reduced to 25852.38 t /a, and TP 351.28 t / a. 2)The prediction and analysis on the improvement of water quality in Wuliangsuhai lake Lake area �Simulation solutions

In order to survey the improvement of water quality in Wuliangsuhai lake Lake area by implementing the project by World Bank, a 2-year simulation has been conducted for these two solutions set out in Table 5.2-37 based on the hydrodynamics and water quality models set up by this project. During this simulation, the load variation of the general drainage canal affecting the improved performances of water quality in Wuliangsuhai lake Lake area has just been taken into consideration due to less flow discharge of the eighth and ninth drainage canals compared with that of the general drainage canal. The solution II in Table 5.2-22 represents the waterexit load flowing into the wetland from the general drainage canal in the wetland design program. And the load in Solution I represents the inflow load from the general drainage canal in the wetland design program plus the reduction amount of load from upper reach industrial zones, which is used as the inflow load from the general drainage canal without the project by World Bank, where the two solutions of the water amount from the general drainage canal keep in line.

Note: the total reduction amount of the industrial zones is distributed into 12 months in equal proportion, incorporating into the design inflow load of the wetland, which is used as the inflow load without the project by World Bank.

The status in quo of the water quality in lake area refers to the monitoring data of status in quo in Table 4.2-29, the status in quo of the water quality to simulate each grid are acquired by the interpolation of surface divisions of Wuliangsuhai lake Lake as the initial value of the model simulation. This simulation is the prediction conducted based on the information data learned from the status in quo and the inflow data of the general drainage canal is configured according to the monthly mean data from a thorough year from May, 2008 to April, 2009, and the acquired data for the general drainage canal is also monthly mean data while the outflow configuration of Wuliangsuhai lake Lake is conducted based on the existing and simple information data. According to the status in quo, this simulation predicts two kinds of solutions, simulates the relative variation of the water quality in Wuliangsuhai lake Lake, so as to survey the effects of the project by World Bank. However, since the continued impact of the inflow of the pollutants load before May 2008 has not been taken into account, what has been simulated is the contrast of the two solutions, which can’t stand for the true value, but basically reflect the effects of the project by World Bank. The hydrodynamic conditions of the simulated lake area are under the circumstance that the planned grid water channels exist.

� Simulation results

The key to Wuliangsuhai lake Lake is the issue of eutrophication and the monitoring data of the existing NH3-N concentration indicates that the water quality basically exceeds Grade V water. Therefore, the simulation results contrast of the two solutions will be represented by NH3-N concentration for contrastive analysis. The ratio of the water body area with different water quality accounting for the total lake area referred to NH3-N concentration after various time periods is shown in Table5.2-38. The distribution contrast of NH3-N concentration is shown in Fig 5.2-9-5.2-14.

The contrastive analysis on the results indicates that, generally, the implementation of the project by World Bank will remarkably improve the water quality in Wuliangsuhai lake Lake and the water quality of the status in quo will be gradually turning to above Grade IV water for the better, which will be faster that the solution without the project by World Bank. With the time going by and the diffusion mobility of the pollutants, the effects of Solution II will gradually be reflected; the simulation effects on 240th day, 300th day and 36oth day indicate that (Table 5.2-38, Fig 5.2-12-5.2-14) the implementation of the project by World Bank will have remarkable improved performances to the water quality in Wuliangsuhai lake Lake; the ratio of Grade � water accounting for the lake area will reach 0.231-0.283, lower than that of Solution I by 0.053-0.075;the ratio of Grade III water accounting for the lake area will reach 0.538-0.573, higher than that of Solution I by 0.301-0.436. But because of the poor reduction amount of pollution in Nov and Dec in 2008, the inflow pollution load is far mare than that in Oct; and because of the poor hydrodynamic force conditions within the inflow area of Solution II, the pollutants can’t rapidly diffuse, which, as a whole, results in the NH3-N concentration within the inletting area of the lake of Solution II obviously on the high side. As stated previously, in order to increase the effects of the project, it is suggested in this environment assessment that the construction of gird water channels at the outflow port of the

inflow wetland of the general drainage canal should be increased, namely at the lower reach of inlet port from wetland into Wuliangsuhai lake Lake and the northern part of East Big Beach (the red ellipse area in Fig 5.2-15), so as to improve the hydrodynamic force at the inlet port, meanwhile, to strengthen the pollution control in Nov and Dec to take best advantage of the implementation effect of the project by World Bank.

The suggested channel area to be added to

out in this project mainly is based on the analysis and comparison of the follow-up monitoring data of Tai Basin urban� Environment Project financed by the World Bank which includes the dredging of Wuli Lake. The a Wuli Lake ecological dredging engineering was conducted by Wuxi Municipality in 2002 to dredge the sediment and control the severe pollution in the north area of the lake. After completion of this engineering, related departments undertook synchronous follow-up monitoring assessment for Wuli Lake and the surrounding lake areasthe results show that1) after the project implementation, the water quality of Wuli lake was improved obviously. The COD Mn of the lake presents more obvious downtrend generallyand the standard of surface water was upgraded from water quality Class-IV to Class-III standard (below 6.0mg/L)2) The TP concentration in the water body basically remains at about 0.10~0.15mg/L, decreasing by 50%compared with the average value of 0.16~0.2mg/L before 20023) The TN content has wide variation but presents a general trend of reduction, the testing values are basically close to about 4.00~6.00mg/L, slightly lower than that after dredging 4) Engineering has presented apparent effect on reducing the content of chlorophyll a in the lake.

Since the project will upgrade the water quality of Wuliangsuhai lake obviouslyand the construction methods of Wuliangsuhai Lake engineering and Wuli Lake engineering are basically similar, both adopting environmental friendly dredging technology to conduct construction. Therefore, the follow-up monitoring result of Wuli Lake engineering is of great consultant significance to the aquatic ecosystem environmental impact analysis of this project and can be used as analogy basis.

�The impact on phytoplankton

Phytoplankton (algae) is the primary producer of the lake ecosystem and the basis of material and energy flows in the aquatic systems. Because the phytoplankton has high sensitivity to environmental conditions, thus, species composition and distribution are subject to significant influence of environmental factors. After the implementation of the project, it is subject to the affect of the water flow, water quality and water depth and other changed conditions, the species, community structure and spatial distribution of the phytoplankton will occur certain changes.

The tracing investigation and monitoring results of the phytoplankton in Wuli Lake, shown in Table 5.2-31.

From the survey results table, we can see that in the survey of July 2002, before the dredging, the dominant species of algae in Wuli Lake are particles melosira and oscillatoria etc., which belong to cyanophyta, regarded as an eutrophication indicator. In July 2003, after the dredging, the dominant species of algae are chlorella and microcystis, the density of algae decreased significantly, which reflects that the eutrophication of water decreased when the overall project was over. This explained that in short time after dredging and removing the sediment, the phytoplankton community structure has the trends of changing into clean water-based community. However, because the pollution of Wuli Lake external sources is not effectively controlled, the quality of water is changing; in the water of the dredging area, the algae species also are corresponding changing. In December 2003, the density of particles melosira in water rose, which has been the most dominant species in some monitoring points. In July 2004, the dominant species in Wuli Lake water is little yellow silk algae, algae density as high as 1529 × 104 pcs / L. To half a year later, in January 2005, pond N.Linckin became the dominant algae. From above analysis, we can see that the implementation of the project has the positive effect for favorable transformation of the phytoplankton community.

Because the work is a thin layer precise dredging, the main effects of the ecological dredging project on the phytoplankton reflected the changing of water quality in the lake. According to the foregoing analysis, after implementation of the project, under the conditions that other external conditions in the lake do not change, the inner sourcesof pollution from the lake sediment in the will be reduced. The water quality will be improved to some extent. From the comprehensive analog data results, we can see that in small scales, this project will help the phytoplankton community structure of Wuliangsuhai lake to change into favorable direction. The species and community of alga will occur correspondingly to the change of eutrophication of the water quality and water body change.

According to the region characteristics of Wuliangsuhai lake, since the construction area and the areas around the Lake are connected with each other, the species of the phytoplankton and biomass changes in the project area is still mainly determined by the changes of environmental conditions in the great lake region, the effects caused by the dredging on the spatial distribution heterogeneity of the phytoplankton is very weak.

�The impact on the zooplankton

According to follow-up survey, before the implementation of comprehensive treatment, the dominant species of the zooplankton in Wuli Lake is calyciflorus rotifer, which is a significant indicator species of sewage domain. At the time that the comprehensive treatment project has been just completed, the dominant species of zooplankton are rotifer class and sand shell worm with sarcodina, commonly have, calyciflorus rotifer, Galeazzi seminal vesicle and spherical shell sand worm etc, which belongs to moderate contamination indicating species .One year later after the completion of the project, we can not find contamination indicating species in the sampling points of the lake region, we can find oligosaprobic zone zooplankton, we can also find heroic Cyclops, show body fleas, these species grow in clean water, which shows the eutrophication in the water has been mitigated.

The main food source of the zooplankton is the phytoplankton, therefore, the changes of species, and biomass of the phytoplankton is affinitive with the changes of the phytoplankton. After implement of the construction, because the dominant species of the phytoplankton changes, the species components of the zooplankton also changed with it. According to analogies analysis, the plankton species and quantity in this project have the same changing trend with that in Wuli Lake. Shortly after implementation of the project, the changes of the phytoplankton are little; the total pattern of the zooplankton is similar with the current.From the long-term perspective of effects, when the quality of water is improved, with the falling of eutrophication and improving of water conditions, the zooplankton community structure will become stable, the zooplankton population structure will change, the dominant species of the zooplankton in the water also will change, the community structure will gradually change into clean water type biological and bio-diversity has the trend of rising.

�The impact on the benthic fauna

When the project is implemented, due to the ecological dredging project removed the heavy pollution of lake sediment on surface of the sediments, the lake water quality is improved at some extent, the eutrophication of the water is reduced, the habitat environment of the benthic fauna and environment conditions will be improved at some extent. But recently, because of the effects of dredging construction, in a short time, in the area of dredging project, the habitat environment of the benthic fauna is destroyed, the area, species, quantity, population structure and niche of the benthic fauna will be affected greatly, the benthonic animal, number, and biomass will be reduced at some extent. Table 5.2-33shows the monitoring results of Wuli Lake, before constructing, the biomass of the benthic fauna is 26.154g/m2, after the constructing, the biomass decreased obviously, particularly in June 2003, the sampling results showed that the biomass has reduced substantially than in July, 2002, which shows that the removing of the surface sediment make the original sediment environment change obviously, in a short time, the benthic fauna is affected at some extent. From the survey results in July 2004 and January 2005 one year later after the constructing, the biomass of the benthic fauna was still very low, which showed before the artificial restore measures are not being taken, the dredging has more serious impact on the benthic fauna, the natural recovery process of the benthic fauna is very slow, its new niche will take a long time to fully be established.

�The impact on the aquatic plants

When the construction began, 20-40cm of contaminated sediment is removed, which caused the seed bank of the aquatic plants disappeared within the area of dredging in the lake region, and the new soil surface is denser than the original sediment conditions, when the constructing is completed, the attachment and growth of the initial aquatic plant root will be subject to effects at some extent. Within 1 to 2 years after the constructing, the restoration of the aquatic plants within the area of construcing will only conduct depending on the way of vegetative propagation; the restoration speed is very slow, and restricted by water depth, transparency and other external conditions. From the long-term changing trend, under the conditions of improvement of the water quality and eutrophication, the implementation of the construction will benefit the restoration of aquatic plant communities.

�The impact on fish

During the running period, because Pollutants in the Lake were Cut-off and the sludge was dredged in the Wuliangsuhai lake, thus reduced the releasing of nutrient salt to the water, which can help improve water quality, provide a good external environment of growth and survival for fish; Otherwise some depth of dredging increased depth of the water body, and increased activity space of fish; after construcing, artificial releasing of benthos and cultivation of aquatic organisms, the system food chain was enriched, which provide necessary external conditions for fish to live and reproduce, and produce favorable impact on the fish.

5.3 Mitigation Measures 5.3.1 Mitigation Measures in Construction Period 5.3.1.1 Mitigation Measures for Environmental Air Contamination Main atmospheric contaminants generated in construction period for this project are malodor and dust.

�1�Control Measures for Malodor y� Construction for the grid-like watercourse work of Wuliangsuhai Lake area will be done in dry

season section by section. The excavated sediments and wastes shall be transported to local landfill in time for harmless disposal.

y� If the excavated sediments and wastes can not be transported in time, to avoid the effects on the life quality of nearby residents, the sediments shall be loaded into the straw bags for storing to reduce the release of dust and malodor.

y� The transporting of the sediments shall be closed to prevent them from scattering along the road for which will affect the image of the city.

y� Attention shall be paid to the personal protection of the construction staff as well as the inspection work and first aid.

�2�Control Measures for Dusts y� Project management shall be strengthened and the construction being civilized. Loading and

unloading for building materials shall be proper and gentle. The soil adhered to the surface of vehicles shall be removed as much as possible before they leaving from construction sites. When transport limes, aggregates, cement, fly ash and others, transporting vehicles shall be covered with tarpaulin, for which are very easy to generate dusts.

y� Dusts in construction sites and construction roads can be controlled by watering and cleaning. If only do the watering and then cleaning, the amount of dusts can reduce 70 to 80%, while first do the cleaning and then watering, the efficiency of dust control can reach 90%. Tests show that each day do the watering 4 to 5 times to control the dusts in construction site, the dust contamination can be reduced from the scope of 20 ~ 50m. One sprinkling truck shall be provided for each construction site.

y� In addition, lime, sand and others can not be stockpiled in the open as much as possible. If these materials must be stockpiled in the open, watering shall be done for these stockpiled materials to improve their surface water content for which can also play a dust control effect.

y� The selected construction unit shall have a certain strength/qualification, which use commercialized plant-mixed cement and closed-transporting vehicles.

y� For temporary and scattered cement mixing sites, the selection of the site shall consider as far as possible away from the residential buildings.

y� The spoil shall be transported to the low-lying site appointed by the municipal administration department for filling disposal or to the landfill as soon as possible.

y� For the temporary used land, vegetation cover shall be restored to against soil erosion once the work is finished.

y� Dust contamination shall be controlled in construction period, for the residential areas being distributed around each construction site of this project.

(3) Control Measures for Waste Gas of Vehicles The fuel machine and transport veicle for construction shall be equipped with tail-gas purifying devices before operation on the site and use high-grade lead-free fuel so as to ensure the tail gas in conformity with emission criteria.

5.3.1.2 Mitigation Measures for Water Environmental Contamination 1�Treatment Measure of Wastewater in Construction A sedimentation tank shall be built by the construction unit in construction period. With the tank, waste water, piling mud water and standing water and others generated in construction can be discharged outside after precipitating and meeting the requirements. y� Simple living facilities built on construction sites mainly are temporary canteens and temporary

toilets. The waste water from the canteen shall be pretreated by grease trap before combining with domestic wastewater. All waste water shall be sent into the nearby wastewater treatment plant for treatment and discharging outside after meeting the requirements. If there is no nearby wastewater treatment facility, necessary classification shall be done for the waste water generated from the project construction and pipeline construction through the collecting pools, sand pools, drains and other water treatment structures. And the nearby farmers can take them as agricultural fertilizer.

y� During construction, construction workers shall make use of the existing living facilities near the construction site as much as possible. The contractor shall take all necessary measures to prevent

the untreated waste water directly flowing into the existing drainage canals or other surface water bodies.

y� The management of construction site shall be strengthened. The working field and the stockpiling slope of the earthwork shall be keep tidy and in order, so that the earth can be reduced to flow into the nearby rivers.

y� To reduce the amount of generated waste water, materials loss, scattering and overflowing shall be controlled as much as possible.

y� Construction materials such as cement, sand and lime shall be concentrated for stockpiling. Note such material can be stockpiled near the rivers or other water bodies, it is better that the stockpiling site is far away from the rivers with some water against measures being taken. Scattered materials for the above during transporting shall be cleaned in time, so that the materials can be avoided being washed into the water bodies by rainwater. Environmental management shall be strengthened. Note the oil leakage or waste oil dumping for construction machines or construction vessels shall be avoided, for the oil can cause water pollution after entering into water bodies. It is recommended that the leaked oil from construction machines shall be received by some means.

y� All construction waste water is strictly forbidden to discharge into the ground surface water body near the construction site without treatment.

2) Control Measures for Water Pollution in Excavation of Grid Canals in Wuliangsuhai Lake y� A reasonable proposal should be selected for the construction of sea area grid waterway works of

Wuliangsuhai Lake, so as to minminze the decline of water environment quality of some sea area of Wuliangsuhai Lake caused by the release of pollutants in grid excavation.

y� Hydraulic backhoe dredger & grab-type dredger with little disturbance should be used in the construction. After substrate sludge is shoveled up, the turning device moves the bucket to over the sludge barge. A bucket opening device drives a pin and presses down a buffer spring. The bottom of the bucket will open with the force of dead weight & load and unload sludge. No leakage of substrate sludge in excavation exists by and large. The excavated sludge is directly conveyed to the barge around and fills up a fleet of barges, which will be dragged by a tractor to the dumping grounds.

y� Hydraulic backhoe dredger and grab-type dredger work on designated positions in the construction, so as to reduce the disturbance upon substrate sludge and the impact on suspended substance in spreading.

y� Seepage cut-off ditch is set up at dumping ground of substrate sludge, and the leakage water is timely pumped into reed wetlands for treatment after at least 48h settlement.

5.3.1.3 Mitigation Measures for Noise Contamination According to the acoustic environmental impact analysis of construction period, we can see that noise from the construction site has a greater effect on surrounding acoustic environment. Moreover, there are a lot of sensitive points being distributed around each worksite. Therefore, corresponding noise control measures shall be taken by construction units to minimize noise effects on the environment. �1�Strengthening project management and arranging construction schedule properly A scientific schedule shall be prepared with construction work time being arranged properly and noise control regulations for the construction being observed strictly. Note the high noise equipments shall not be applied intensively at the same time as much as possible. The construction is not allowed from 11 pm to 6 am of the next day, if the worksite is � 200m to the residential areas. Furthermore, low noise machines shall be considered in the selection of construction equipments and plans as much as possible. Construction time for high noise equipments shall be arranged in the day time and minimize their working time at night. For some of working sites, if the construction must be done at night with the noise affect the environment of the surrounding residents greatly, a permit shall be obtained from the local environmental protection authorities in advance, and this permit shall be posted. �2�Arranging the construction site properly To avoid noise level for part of place being too high, the powered mechanical equipments shall not be arranged in one place intensively. Preparation work shall be well done before the concrete need continuous pouring work. The running time for the mixer shall be minimized.

�3�Reducing equipment noise level y� The selection of equipments shall consider low-noise equipments as much as possible, for

example, use the hydraulic machines to replace the fuel oil one, and the vibrator use the high-frequency type. Moreover, low noise construction methods shall be considered as much as possible.

y� The noise for stationary machines and earth excavation & transporting equipments such as excavators and bulldozers can be reduced by exhaust silencer and isolation of engine vibration components.

y� As the noise level for mechanical equipments can be increased due to the vibration of loose part or the damage of silencer, the maintenance of construction equipments shall be strengthened in the construction, so that the increasing of noise level caused by the poor performance can be avoided.

y� The idle equipments should be closed immediately, and transporting vehicles entering into the site should be slowed down and reduced the times of whistle

�4�Reducing man-made noise y� The operation of equipments shall be in accordance with specification. And in the process of

dismantling for baffles and supports, operational guideline shall be observed to reduce the impact noise.

y� The use of whistle, bell and flute and others shall be minimized in work commanding, while modern equipments shall be applied.

�5�Establishing of temporary sound barrier Around the high-noise equipment, a temporary cover shall be established. And for the location being relatively fixed equipments, these equipments shall be put into the shed as much as possible. Otherwise, a single sound barrier shall be established properly for these equipments outside the shed. �6�During construction, the noise level along the road will be increased for the operation of transporting vehicles. Therefore, the management of transporting vehicles shall be strengthened. The number of vehicles and traffic density on worksite shall be minimized and the whistle for vehicles will be controlled. And the commissioning for equipments shall be done in the day time. Besides the above noise reduction measures for the construction site, good relationship also have to be established with the peripheral units and residents. Before the construction, the units and residents shall be informed in advance if their living affected by the work. To seek a common understanding, the construction progress and the noise reduction measures taken in the construction shall be reported to them. Proper compensation shall be paid to some of units and residents if the construction affects their living greatly. In addition, a telephone hotline shall be established for the complaints from the affected residents, and the complaining information shall be handled actively. 5.3.1.4 Mitigation Measures for Solid Waste Contamination The wastes include the wastes generated from the construction, the garbage created from the living of construction staff and the sediments excavated from grid-like watercause of lake area. �1�According to the results of the monitoring on heavy metal contents of substrate sludge in sea area of Wuliangsuhai Lake by Bayannaoer Environmental Monitoring Station, heavy metal contents of substrate sludge on monitoring points all aren’t higher than the standard in Control Criteria on Pollutants in Agricultural Sludge (GB4284-84) of the State. Therefore, the substrate sludge excavated in sea area grid works of Wuliangsuhai Lake can be used as fertilizer, and upper layer of substrate sludge is used in improving alkaline saline soil; and lower layer is the parent soil with no pollution, about 2.17 million m3, and can be used in piling up artificial island in the lake area, instead of shipment. According to the tourist plan of Wuliangsuhai Lake, many artificial islands will be constructed on the lake. The excavated substrate sludge on upper layer should be shipped to the dumping ground of substrate sludge as soon as possible for pile-up & disposal. The project is built up with four dumping grounds for substrate sludge, which with land occupation of totally 1200mu and operating period of about five years, are equipped with enclosure bank and seepage-prevention system and can meet the pile-up requirements of substrate sludge in the project.

A closed transport vehicle must be used for substrate sludge in order to prevent any leakage on the way, which may deteriorate the sight and sanitation conditions. The burying process of substrate sludge includes operations i.e. transport on designated point, discharge along the ditch and level-off. The workflow is as follows: transport vehicle daily conveys substrate sludge to a dumping ground, unloads from one end of wide ditch to another in the dumping ground, and the excavator will level off and ensure the even distribution of substrate sludge in wide ditch with a thickness of about 0.5m. The ditches are filled up one after another. With high water content, substrate sludge will be dried by strong sunlight and vaporization naturally, instead of compaction or coverage. Later, it will be piled up again to 2.0m high. To prevent the generation of fly and maggot, liquid medicine or lime can be sprayed on the surface of substrate sludge every several days, and moreover, labor safety and protection for workers are required for preventing epidemic. After substrate sludge is filled up to a preset height, a 30cm-thick undisturbed soil should be covered on the sludge. In light of the daily treatment quantity of the substrate sludge and effective operation distance of excavator, the workload quantity per day is taken as one operating unit. �2�Spoil and construction wastes shall be filled in appointed site according to the requirements of municipal administration department and planning department. If the backfill site is not used temporarily, vegetation cover shall be cultured to prevent the soil erosion. �3�Abandoned material in the construction such as gravel, building materials, steel, packaging materials shall be recovered by special people. And the working face shall be cleaned timely without any sequelae left. �4�To prevent secondary pollution, domestic garbage shall be collected specially and sent to landfill regularly for proper disposal. Huddle and throw is forbidden strictly. In addition, to ensure the living environment and hygienic quality of the surrounding environment for the workers, the contractor shall strengthen the education of construction staff that waste can not be thrown at their will. �5�When confront hazardous wastes in the construction, the work shall be stopped temporarily,. And the local environmental protection department and health department shall be contacted in time. After handling measures being taken, the construction can be started again. 5.3.1.5 Protection Measures for Ecological Environment 1)Mitigation Measures for Soil Erosion During construction period, because the excavation amount for the ground surface is very large with lots of spoil and serious damage to vegetation cover, proper measures have to be taken for this situation. Otherwise, soil erosion will appear with a several-fold increasing trend for the project site. Therefore, strict environmental protection measures shall be taken to control the soil erosion effectively. y� Before the construction of each engineering facility and the pipe work, conditions of underground

engineering geology and underground obstacles shall be understood firstly, for which is the prerequisite and basis of a project.

y� The construction of each engineering facility and the pipe work shall avoid the rainy season. And drainage channels shall be built of the construction sites with serious soil erosion. The construction will take methods of stratified excavation, layered stacked and layered backfill. After completion, the landscape will be restored and the construction shall be in accordance with the design requirements of water-soil conservation strictly. During the construction of water intake work for the reclaimed water supply project, this work shall be done in dray season in order to avoid the effects of wet season for which is a flood season and last from June to August.

y� The planning and design shall be considered properly. The existing roads shall be used fully with no or less construction road working.

y� To reduce construction errors and increase work efficiency, the information based construction shall be strengthened.

y� The earthwork in the construction shall be done properly. Excavated earth shall be used for backfilling of the construction site as much as possible. Besides for backfilling, the spoil

generated from pipe-laying and construction shall be sent to other construction sites for filling and greening work soil or sending to the landfill.

y� Project construction shall be done in phases and area by area. Do not spread the work fully to shorten the single completion period, especially the pipe-laying work. Measures shall be taken for the excavated exposed ground surface, and the exposed time shall be minimized to reduce the soil erosion.

y� To fully consider the effects of greening work on soil erosion control, it is recommended that the construction of each work for individual structure shall be done one by one if possible. To minimize the soil erosion, the greening work shall be done based on worksite greening plans as soon as the work finished.

y� Building materials like cement are not allowed to stockpile near the water bodies, canopy cover and fence shall be set to prevent the rainwater washing them into the water bodies. Appropriate sites shall be selected for the construction wastes (including spoil and abandoned stone) to backfill or stockpile after consultation with the local people. The spoil and abandoned stone shall be used as much as possible for road foundation work and soil conservation project.

y� If the pipeline construction faces these items such as high voltage pole, overpass, main traffic road, municipal pipe network and relevant road, reports have to submit to the relevant management departments. Based on their approvals, the work can be performed. The supports for the nearby buildings (structures) like residential areas and bridges for which are in the scope of the pipeline construction effects shall be considered, especially the effects on ground settlement, nearby buildings (structures) and existing underground pipeline.

y� During construction, the damage to vegetation cover shall be minimized. After construction, measures like planting tree and grass shall be done to speed up the recovery process of vegetation with some engineering measures also being taken for protection. To protect the integrity of the ecosystem, the original land surface height shall be maintained and the landform be restored as original after the completion of construction.

y� Before construction, the construction unit shall prepare detailed construction plans and establish environmental management systems. Special people have to arrange to responsible for the environment protection work during construction. Corresponding control measures and disposal methods shall be made for the “three wastes” generated in the construction. The environment management shall be in accordance with the national environmental guidelines, policies, regulations and standards. To be rule-based and scientific management, various environmental management system shall be established which take post responsibility as the center.

y� To be civilized and cleaned construction, the education of construction staff shall be strengthened with environmental regulations and environmental knowledge being learned.

2) Mitigation Measures for Landscape Ecology Impact y� Define a proper construction proposal, carry out scientific organization and orderly construction,

pile up waste soil of the works at designated place, and take protective measures such as water spraying for preventing flying dust of dumping ground.

y� Strengthen the management of construction site, and cover building material and earthwork transport vehicles with tarpaulin and prevent & control flying dust in transport.

y� Clean and spray water over the construction site and construction road regularly, and prevent & control flying dust on the road.

3) Mitigation Measure for the Impact of Sea Area Treatment Works of Wuliangsuhai Lake y� To prevent the impact of aquatic ecological environment, scientific and reasonable construction

management should be applied in the construction of lake area grid waterway works. y� Zone-by-zone & site-by-site construction and operation at designated place can be used for

preventing widespread disturbance of substrate sludge, so as to reduce the spreading of suspended substance and the impact on the aquatic ecology.

y� The equipment and tool with little disturbance upon substrate sludge should be selected in the construction for reducing disturbance on benthonic realm.

y� Select low-noise construction machine, reasonably organize & arrange the construction, take artificial noise-reducing measure, and lower the impact of construction noises.

y� Strengthen construction management, reduce damage of vegetation, take artificial measures after construction, and speed up recovering process of vegetation, and take some engineering measures for protection.

5.3.1.6 Mitigation Measures for Social Environmental Impact

y� The reasonable acquired land compensation for the villagers shall be in accordance with the land acquisition and resettlement policy and compensation approach of the relevant national government and local government. The villagers’ opinion shall be listened carefully. The working and living conditions for the villagers shall be guaranteed that not lower than the current level.

y� Construction for pipeline and lake area shall be done section by section. The excavation and backfilling shall be done as soon as possible. The construction sites, which near the public facilities such as hospital, school and bus station, shall have temporary pavements and warning signs. During the rush hour, traffic policemen shall give guide and dispatch to ensure smooth flow of pedestrians and vehicles. To reduce the pressure of urban traffic, the transporting of materials shall avoid the rush hour.

y� Awareness training and education of cultural-relics protection for the management and construction staff shall be strengthened. According to field survey information, no cultural-relics have been found currently in the project area. However, if find any cultural-relics in the construction, the local conservation department shall be informed immediately. The site shall be preserved in time and the construction shall be stopped before the proper handling done by the conservation department.

y� To reduce the possibility of traffic jam and the effects on traveling of the residents, the transporting of building materials and waste earth shall be done at night or avoiding the rush hour.

5.3.1.7 Human Health To ensure the construction safety, the contractor shall prepare the health and safety approved by the relevant project management unit (PMU). The contractor shall prepare the induction training program for the construction staff. The facilities like cranes, supports and other shall be fixed rigidly. To avoid the occurrence of personnel casualties, the construction staff shall observe the construction specifications such as Code of Design on Building Fire Protection and Prevention and Specification of Building Safety strictly and wear the personal protection equipments like safety helmet. During construction, the contractor shall avoid transporting the materials in rainy day or at the time of go on/off shift to against traffic jam or accident. To avoid public casualties, proper isolation and protection facilities shall be installed and warning device shall be set up for dangerous sites with special personnel for caring. An effective organization responsible for environment supervising and monitoring shall be established, which can start a fast and efficient procedure for any violation. Detailed environmental and social impact specifications shall be prepared for the contractor and which shall be included into the tender documents. And the obligation for environment must be taken as part of the contract documents. 5.3.1.8 Cultural Resources Although the local cultural departments and site survey for each component have confirmed that there are no physical cultural resources within the project area, the followng Chance-fine procedure should be followed once any physical cultural relics are found during the construction stage: The construction should be stoped immediately once any physical cultural heritages are discovered and the local cultural department and specialist should be reported; The site should be protected by the contractor and should not constructed until the local cultural department issued a permit. 5.3.2 Mitigation Measures in Operation Stage 5.3.2.1 Reclaimed water supply Project 1�Analysis on Water Pollution Control Measures �1�Pollution control measures of Reclaimed water supply project

�2�Feasibilities Analysis of Water Pollution Control Measures of Reclaimed Water Supply Project

y� The pollutants components of settling tank sludge water, filter backwashing water and pressure-filtered water from sludge dewatering chamber of this reclaimed water supply project are rather simple and main of them are SS. So, after settling, the water quality will be improved greatly, meanwhile rather little wastewater will be generated. This will take a small proportion of the scale of the whole reclaimed water supply project; also, this will have little effect on inlet water quality of reclaimed water plant but will not cause shocks to normal operation of reclaimed water supply facilities.

y� In consideration of brine wastewater caused by ultra-filtered and reverse-osmosis technologies applied in reclaimed water supply project of Drainage Cannel 3, Drainage Cannel 7 and Ganqimaodu Port Processing Park, the wastewater will be coagulated settled then sent to front distribution and be reclaimed together with source water of reclaimed water plant; such wastewater will not drained outside.

y� Suspended matter and salt content of tail water after reverse-osmosis treatment are rather high, but after neutralization, coagulation and settling treatment, not only the suspended matter but also the salt content will be reduced. After treatment, such wastewater will be reclaimed together with resource water to fully utilize and save water resources. So, this method is feasible to treat brine water.

y� The Wulatehouqi County Processing Park wastewater treatment plant, which is related to this project, is also a project benefit from the World Bank loan; now this plant is under construction and the designed scale is 20,000 m3/d (recent-term); ICEAS process is applied and the construction will be performed from May, 2010 to Feb 2010. Drainage Cannel 3 wastewater treatment plant is located at the south of the Drainage Cannel 3 reclaimed water supply project; A2/O process is applied and this plant is completed and in trial operation, the designed scale is 20,000 m3/d. Drainage Cannel 7 reclaimed water treatment plant is located at the south of the Drainage Cannel 3 reclaimed water supply project; this plant is under

construction and the designed scale is 22,000 m3/d in recent term and 44,000 m3/d in future term; active sludge Biolak wastewater treatment process is applied. The domestic wastewater drained quantity of Wulatehouqi County reclaimed water supply project, Drainage Cannel 3 reclaimed water supply project and Drainage Cannel 7 reclaimed water supply project take a rather small proportion of the quantity. Meanwhile the pollutant of such domestic wastewater is single and the content is rather low. When the water flows to the plant, it will take little effect on designed inlet water quantity and quality of the wastewater treatment plant.

y� Therefore, it is feasible that the domestic wastewater caused by reclaimed water supply project engineering and operation is sent to wastewater via network treatment plant nearby and to be treated

y� Noises from equipments can be abated effectively to meet concerned national standard by above methods.

3� Solid Wastes Management Measures �1�Solid wastes control measures of reclaimed water supply project The solid wastes produced by the water supply engineering of reclaimed waterof this project mainly include sludge from reclaimed waterdisposal and the domestic garbage. The sludge from reclaimed waterdisposal is first treated through concentration and dewatering until the water content of the sludge is lower than 80%; since the draining water from drainage canals has micro scale of heavy metals, it is necessary to identify the sludge from reclaimed waterdisposal so as to select the final disposal solution for sludge after completion and operation of this project.

In terms of domestic garbage, an agreement has been reached with local department of environmental sanitation that is responsible for immediate cleaning and transportation to ensure the domestic garbage to be cleaned, transported and disposed of promptly and effectively to prevent such materials from producing secondary pollution. y� It is suggested in this environmental assessment that the domestic garbage produced by the water

supply engineering of reclaimed waterof Wulatehouqi County Processing park shall be transported to Wulatehouqi County Refuse Landfill, the domestic garbage produced by the water supply engineering of reclaimed waterof 3rd Drainage Canal to Hangjinhou Banner Refuse Landfill, the domestic garbage produced by the water supply engineering of reclaimed waterof Wuyuan County Processing park to Wuyuan County Refuse Landfill, the domestic garbage produced by the water supply engineering of reclaimed waterof Gqimaodu Processing park to Wulatezhongqi County Refuse Landfill for disposal.

The details on the capacity and construction progress of the landfills to accommodate the sludge from this component are shown in Table 4.4-8. The design capacity of the municipal refuse landfill of Longxingchang Town, Wuyuan County, is 199t/d. The technique adopted is in line with the mordern sanitary landfill. The service scope covers Longxingchang Town. So far the main civil works and part of the affiliated structures have been completed, the transfer stations, and transporting vehicles have been in preparation.

The design capacity of the municipal refuse landfill capacity of Hangjinhouqi County is 80t/d, which is started to construct in June 2010 and will be operational by the end of November 2010. The service scope covers Shanba Town. The technique are sanitary land fill. It is expected that the refuse landfill capacity of all counties under the project will have adequate idle capacity to accommodate the garbage from this project.

y� Qualified departments will be entrusted to identify the constituent of sludge produced from the

wastewater treatment and reclaimed water plants with reference to Identification Standards for Hazardous Wastes- Identification for Extraction Toxicity (GB5085.3-2007) .Two disposal solutions for sludge are as follows:

The first is that when the sludge from wastewater treatment and reclaimed water plants is identified not to be hazardous waste, it will be treated as common industrial wastes, together with the domestic garbage produced by the water supply engineering of reclaimed water, respectively transported to Wulatehouqi County Refuse Landfill, Hangjinhou Banner Refuse Landfill, Wuyuan County Refuse Landfill, Wulatezhongqi County Refuse Landfill for disposal. The second is that if the sludge from wastewater treatment and reclaimed water plants is identified to be hazardous waste, it must be disposed by Baotou Hazardous Waste Disposal Center, Inner Mongolia, for disposal ( at Midwest of Inner Mongolia). Baotou Hazardous Waste Disposal Center has been operated in line with national regulations for hazardous waste management and it has a cerified tanker fleet and a certified waste transportation procedure. A preliminary agreement has been reached with Baotou Hazardous Waste Disposal Center on the transportation and disposal of the sludge.

Inner Mongolia Baotou (Mid-west area of Inner Mongolia) Hazardous Waste Disposal Center has been established in line with the National Construction Planning of Hazardous Waste and Medical Waste Disposal Facilities, issued by the national State Council. The overall investment is 198 million RMB and the site is located in the west of Hatamen Valley, Agarusutaimu, Jiuyuan District, Baotou City. The hazardous substances from eight cities, including Baotou City, Hohhot City, Erdos City, Wuhai City, Xilin Gol City, Ulan Qab City, Bayannaoer City, Alashan League, and medical waste disposal facilities of Baotou City will be disposed safely here. This center (1st stage) takes coverage of 36 thousand m3 and the overall capacity is 203367m3 The annual landfill quantity is 28760m3/a. The disposing capacities include: incineration 10,800t/a, waste acid 30,000t/a, physical & chemical disposing 5,000t/a and curing process 15,500t/a. Because that sludge produced in the reclaimed water plant is only 4,600.72t/a, Inner Mongolia Baotou (Mid-west area of Inner Mongolia) Hazardous Waster Disposal Center is capable to treat sludge from the reclaimed water plant. This disposal method is feasible.

�2�Proposal for reclaimed water project solid waste control y� Solid wastage of wastewater treatment plant, especially the sludge shall not disposed casually but

y� Strengthen management of each treatment system of wastewater treatment plant and remove deposited sludge. When the wastewater tanks are stopped to maintenance, the sludge will be emerged, so that the odor will come out. The sludge shall be removed timely to reduce odor.

y� The sanitary protection distance of this project is 50m. The sources of odor are 10m or farther to factory boundary. It is recommended that 40m distance away from the boundary shall be arranged as plan control area, in this area, no civil building or other sensitive permanent buildings are allowed to be built. 2� Measures to Mitigate Water Pollution After this project is completed, the water quality of general drainage cannel in Hetao District will

be improved tremendously. To ensure normal operation of wastewater treatment plant, following measures shall be taken during plant operation:

�1�Reform the heavy pollution enterprises on-site. Close, stop, merge, change or shift unqualified enterprises.

�2�To ensure normal operation and qualified tail water to be discharged as per national standard, enterprises in the Park shall discharge their wastewater to network before their wastewater is treated respectively as well as the industrial feature pollutants are removed. The wastewater to be discharged shall meet Discharge standard for municipal wastewater (CJ3082-1999). The wastewater from sludge de-water chamber and domestic wastewater shall be collected in wastewater network and then be send to treatment process.

�3�The wastewater from heavy pollutant enterprises shall be pretreated in their factories before being discharged. An accident reservoir shall be built to void high load shock to wastewater treatment plant so that the treatment efficiency and tail water quality being affected.

�4�To prevent risk of accidents, starting from design and management, practicable measures shall be taken and accident emergency disposal system shall be established.

�5�Strengthen water pollution monitoring. Install online monitoring devices, which are linked with local environment protection department, in inlet and outlet of wastewater treatment plant. All wastewater treatment plant shall equipped with accident emergency reservoir.

�6�Operation management and operation responsibility system shall be well established; Staff members shall be well trained and technical evaluation files shall be set up for them. The unqualified staff shall not work.

3�Measures to Mitigate Noise Pollution

The noises of wastewater treatment project mainly come from the equipments, which include mechanical equipments like wastewater pump and ventilators, in wastewater treatment plant and wastewater lift pump station. Following measures can be applied to control noise pollution.

1 To select low-noise ventilator, wastewater pump.

2 Compound impedance silences are applied in the inlet and outlet.

3 Use Isolation booth to control noises.

4 Take measures like vibration elimination, noise isolation and underground channel ventilation for aeration tank ventilator room.

5 The ventilator room control can be realized in Central Control Room so that the operators are not required to work in the ventilator room.

�6�A greening belt with certain width is required in the factory boundary. Arrange tri-layer arbor-shrub-arbor green belt and grassland under trees to eliminate the noises.

4�Measures to Mitigate Solid Waste Pollution �1�Sludge Treatment Method There are several methods to treat sludge, major of them are landfill, compost and incineration.

Although the constituents of the sludge to be genrated by this component is not clearly identified in the EA stage, according to analog data, the constituents of sludge of wastewater treatment plant are related to the properties of wastewater to be treated. Normally, the sludge from a wastewater treatment plant, which mainly take up industrial wastewater, contains high level heavy metal content which is much higher than the standard for sludge for agricultural application. Therefore, the sludge from processing park shall not be utilized as agricultural fertilizer. Instead, it shall be disposed by means of sanitary landfill. Inner Mongolia Baotou (Mid-west area of Inner Mongolia) Hazardous Waster Disposal Center will be assigned to treat such sludge. The profile of Baotou Hazardous Waste Disposal Center is showed in 5.3.2.1�Because that sludge produced in this processing park wastewater treatment plant is only 4,307t/a, Inner Mongolia Baotou (Mid-west area of Inner Mongolia) Hazardous Waster Disposal Center is capable to treat sludge from this processing park wastewater treatment plant. This disposal method is feasible. See hazardous and waste treatment agreement of this project in attachment.

(2) Disposal of screenings and domestic garbage

The screenings intercepted by fine and coarse screens are mainly solid substance, including both inorganic and organic substance. They have the properties similar to the domestic garbage and must be properly collected, stored and disposed of. Specific pile-up, packing and transport shall strictly follow the regulations. All domestic garbage must be in bagged. Full-time personnel should be designated to collect and send to the pile-up site designated by local environmental department, and conveyed by garbage truck in timely manner to the solid waste landfill facilities. It is suggested that the screenings in wastewater treatment and domestic garbage of Wulatehouqi County Processing Park should be hauled to the garbage landfill site of Wulatehouqi County; the sludge in wastewater treatment and domestic garbage of Wulateqianqi County Processing Park to thelandfill site of Wulateqianqi County, and the screenings in wastewater treatment and domestic garbage of Ganqimaodu Processing Park to the garbagelandfill site of Wulatezhongqi County. The capacities and construction progress of the garbage landfill sites in the project counties for the project are included in Table 4.4-8. It shows that the construction progress and disposal capacity of the garbage landfill site in the countires can meet the requirement of the project.

Dredged sediment and doimestic garbage shall be transported in tankers, in order to avoid spillage or affect scenery and sanitation. The capacity and construction status of refuse landfills of the project counties are shown in Table 4.4-8. The design landfill capacity of Wulashan Town, Wulateqianqi County is 100t/d. The techniques are sanitary land fill. The service scope covers Wulashan Town. So far the civil works of the landfill have been completede and will be ready for use by the end of 2010. The design landfill capacity of Hai liutu Town, Wulatezhongqi County is 70t/d. The techniques are sanitary land fill. The service scope covers Hailitu Town. So far the civil works is under construction and will be ready for use by the end of August 2011. The design landfill capacity of Wulatehouqi County is 85t/d. The techniqus are sanitary land fill. The service scope covers Ba Yinbaolige Town. So far the civil works in this town is under construction and will be ready for use by the end of October 2011. It can be expected that the design landfill capacity of all the counties can meet the need for disposal of sludge and screenings of the project

5� Measure to Protect Ecological Environment The green coverage may reduce owing to construction. Greening in factory, including greening belt around the factory, grassland in factory and trees beside the roads, shall be performed as compensation. Following measures are recommended to take during greening construction: �1�Pay Attention to Proportion of Arbors, shrubs and grasslands. Keep a certain hierarchical structure. As per greening equivalence defined by ecological service function, an arbor or shrub is equal to 1.5m2 of dense grassland. So, if we enhance the proportion of arbors and shrubs in certain area, the ecological service function will be improved. Meanwhile, a plant community structure including three layer arbor—shrubs—grasses has higher anti-interference abilities. Normally, the green projected area of arbors shall take a proportion higher than 50%, while shrubs 30% at least and grassland 50%(overlapped percentage 130%) �2�Select Mixed Forest Instead of Single-specie Forest Multiple tree species formed by coniferous and broadleaved mixed forest may be applied in greening. Do not use single-specie forest. Economic tree species like poplar, willow and elm are suitable trees to be grown in factory. �3�Use Indigenous Species As Possible The indigenous species fit with local circumstances better and the survival rate is higher. With stronger adaptabilities and capabilities for resisting natural disasters, the indigenous species are preferred tree (grass) species for greening. Local shrubs and grass species shall be selected with sand fixation function.. �4�Strengthen Management

The factory people shall appoint special people for greening and management, also, concerned rules and regulations shall be stipulated to protect grassland and ecological circumstances. 5.3.2.3 Mitigation Measures of Wuliangsuhai Lake Project The operation stage of Wuliangsuhai Lake regulation project is focusing on noise of man-made wetland engineering and solid waste. 1 Measures to Mitigate Noise Pollution The noises of this project mainly come from the pumps of water lift station and compressor of aeration tank. Following measures may be taken to control noise pollution.

y� Double-layer windows and wall material with good sound absorption performance shall be applied in the pump chamber and compressor chamber. In structure, dumper ceiling, damper wall and damper floor shall be selected to avoid transmission of noises. The sound isolation performance shall not be lower than 25dB(A).

y� Low power and low noise type pumps and ventilators shall be selected. y� All pumps and ventilators shall be equipped with bumper base and connected with pipes with

flexible joints. All machines and pumps shall be installed on independent bases to avoid noises caused by resonance.

y� Install silencers to reduce noises of ventilators y� Make a good layout as per the direction of sound, the shielding function of building and

noise-absorbs ion of green plants to reduce noise hazard to staff. y� Vibration-proof and shock-proof shall be considered in arranging, designing pipes and

selecting brackets to abate noises to environment. y� Pay high attention to greening work. Make a three-dimensional isolation belt near the

reclaimed water plant and pump chamber with flowers, grasslands, woodlands and trees. Grow more high and dense trees to abate noises to circumstances.

y� Noises from equipments can be abated effectively to meet concerned national standard by above methods.

2�Measures to Mitigate Solid Waste Pollution Solid wastes produced in lake area regulation project operation mainly include sludge in settling tank and domestic solid waste. The main solid waste generated in the operation of the artificial wetland is sludge in deposition pond, is cleaned every 5-10 years, and should be timely cleaned and shipped out and sent to the garbage dumping site of Wulateqian County for burial treatment. In transportation, some measures shall be taken to prevent secondary pollution caused by leakage. Domestic wastes will be collected and loaded by environmental sanitation department as per the agreement with such department to ensure domestics wastes are removed and sent to the garbage dumping site of Wulateqian County for burial treatment. 3�Mitigation measures for local water cycle impact y� Anti seepage treatment will be adopted by using the buried plastic technology at the outer side of

the reed field in wetland to prevent lateral seepage and infiltration, avoiding soil salinization� y� Strengthen the management of artificial wetland operation, maintain the normal operation of the

anti seepage system to prevent leakage accidents from occurring.

6. Environmental Risk Analysis and Relief Measures 6.1 Environmental Risk Analysis and Relief Measures of Reclaimed Water Supply Works 6.1.1 Environmental Risk Analysis of Reclaimed Water Supply Works The failure of individual equipment of the planned reclaimed water supply works will have no impact on the reclaimed water disposal system by and large; two-way power supply can prevent power cut-off accident and in case of failure of power supply, standby electric generators will timely discharge the untreated reclaimed water into surrounding surface water system for ensuring the safety of reclaimed water supply works while the surrounding surface water system is to be influenced to some extent. Therefore, we’d strengthen the management and maintenance of reclaimed water supply works, and compile an emergency handling proposal for preventing pollution accident of water environment. Chlorine dioxide is used in the planned reclaimed water supply works for disinfection. Sodium chlorate and muriatic acid are purchased for producing chlorine dioxide, with a little chlorine gas as the by-product. Moreover, another key environmental risk of reclaimed water supply works is accident caused by the failure of chlorine dioxide generator in the disinfection. On the basis of the analysis on the damage of the accident, reasonable and feasible prevention measures are put forward for minimizing accident rate, loss and environmental damage of the construction project. Chlorine dioxide, a yellowish red gas with irritative smell can scatter on the ground and is usually diluted to a solution with lower than 10% concentration in use and storage; and with high oxidizability, it may have an explosion reaction with many chemical substance, is extremely sensitive to heat, shock, hit and friction and tends to decompose and explode. Chlorine gas, a yellowish green poisonous gas with irritative smell has a relative density 1.47(0�, 369.77kPa), melting point -101� and boiling point -34.5�, and is dissolved in water and lye. It produces hypochlorous acid and muriatic acid with water, where the hypochlorous acid is then decomposed into muriatic acid nascent chlorine, oxygen, chlorine gas density 2.49, and vapor pressure 506.62kPa (5atm10.3�) and acid. Chlorine and carbon monoxide produces phosgene in intensively heat case. Chlorine gas is non-combustible gas while can support combustion, and explode in mixing with combustible gas in daylight and cause inflammation and explosion with many substances. The chlorine dioxide generator of the project has extremely low output of chlorine dioxide & chlorine gas in abnormal working status. Moreover, chlorine adding workshop is equipped with a lye spraying and absorbing device with processing efficiency of over 98%. Therefore, the accident of the project has a small scope, and in case of accident, timely measures will alleviate the impact rapidly in a short period. In sum, perfect accident handling measures can minimize environmental risk of this project. 6.1.2 Environmental Risk Relief Measures of Reclaimed Water Supply Works 6.1.2.1 Environmental Risk Counter-measures (1) Prevention Measures against Environmental Risk and Accident taken in Design y� Strictly define the production danger area of reclaimed water plant, set up the plan under the

principle of safety and sanitation, take into account wind direction, safe protection distance and other factors, and select corresponding flameproof electric equipment.

y� Set up relevant fire-prevention, explosion-proof, poison prevention, and monitoring, and alarming and other safety facilities for the equipments and pipelines in use according to the properties of chlorine dioxide and chlorine gas.

y� Chemical adding room should be set up with lye spraying system as well as automatic chlorine gas monitoring alarm system.

y� Chemical adding room should be set up with a closed operating cabin of the accident disposal system and waste gas alkaline collecting device in handling accident.

(2) Risk & Accident Prevention Measures in Operation and Management

y� Sophisticated automation system should be used for chemical adding device for effectively controlling production process, timely feeding back the information and shutting down the device in case of accident, so as to reduce the leakage of chlorine dioxide and chlorine gas caused by the accident.

y� Strictly implement the operating regulations, keep to the post, closely monitor the change of process parameters of the equipment, timely report and take effective measures in case of any failure.

y� Chlorine adding room should be provided with forced ventilating equipments. y� Strictly put an end to the leakage of pipeline system, especially the joint between the valve and

pipe, as well as flexible hose and equipment; and carry out regular inspection over pressurized vessel and pressurized component and material.

y� Set up lightning-proof system and fire prevention system; y� Set up cofferdam around the muriatic acid tank with switching device, and build up one accident

collection basin with more than 2m3 volume. In case of leakage accident of muriatic acid, the accident should stay in empty status as usual.

y� The reclaimed water plant should be set up with emergency accident rescue system covering monitoring, early-warning communication, command, first-aide repair and rescue;

6.1.2.2 Relief Measures of Risk Accident (1) Emergency Handling Measures Evacuate the people in leakage polluted area to higher windward position, and close off till the gas completely disappears. Cut off the sources of fire and gas, spray water for diluting, carry out forced ventilation (indoor) or ventilation (outdoor). Gas leaking vessel cannot be reused, for which technical treatment is required for eliminating the remaining gas. (2) Protective Measures

y� Protection of respiratory system: gas mask is required in case of high concentration in the air. In emergency rescue or withdrawal, positive-pressure self-supported respirator is recommended.

y� Protection of eyes: chemical safety protective glasses are required. y� Protection of body: working clothes required. y� Protection of hand: chemical gloves are required for possible touch with poisonous

substance. y� Others: no smoking on the working site. Bath and re-dressing after work, and good sanitation

habits are required. (3) First-aide Measures

y� Skin touch: put off the polluted clothes, and rinse with much flowing fresh water for at least 15min. See a doctor.

y� Eye touch: open the upper & lower eyelids, rinse with much flowing fresh water or physiological salt solution for at least 15min. See a doctor.

y� Inhalation: rapidly leave the site and move to the area with fresh air. Keep smooth breath. Have oxygen therapy in case of difficult breath. See a doctor.

6.2 Environmental Risk Analysis and Relief Measures of Wastewater Treatment and Recycling Works The operation of wastewater disposal plant is usually stable. To minimize the failure, some emergency measure should be defined for wastewater disposal plant and operating management should be strengthened. Several possible cases are analyzed as follows. 6.2.1 Potential Environmental Risk and Accident (1) Emergency Accident Quality problem or improper maintenance of wastewater treatment equipment and facility will cause failure of the equipment and facility. As a result, wastewater treatment efficiency declines and wastewater may be directly discharged instead of any treatment; or some force majeure, such as power shutdown and sudden natural disaster may interrupt the operation of wastewater treatment facility, and a lot of untreated wastewater is directly discharged. This case is extremely abnormal emission of

wastewater disposal plant. In case of abnormal operation of wastewater treatment facility caused by electric power failure, wastewater can only be directly discharged into and pollute the surface water system through overflow pipes. (2) Equipment Failure The failure of wastewater or sludge treatment system lowers the treatment capacity of wastewater. The indicators of outlet water quality fail to comply with the design or sludge fails to timely shrink and dehydrate. As a result, sludge is fermented, and the storage tank is completely packed and smells unfavorably. (3) Impact on Inlet Water Quality The treatment effect of wastewater disposal plant is greatly subject to the inlet wastewater capacity, water quality and other parameters of the plant. According to the State’s statutes on the environmental protection, the emission of industrial wastewater of various enterprises must comply with the standards and the requirements of wastewater disposal plant. In case of sudden accident of wastewater disposal plant of enterprises e.g. power cut-off, its wastewater may be discharged into the wastewater pipeline of the processing area with no treatment and enter a wastewater disposal plant of newly built processing area. In case that inlet waste water causes excessively high impact load, pH value exceeding the scope of 6-9 and the non-decomposable organic poisonous substance higher than the criteria, biochemical and microbe activity of wastewater disposal plant will decline. More seriously, biota is damaged, and sludge is swollen. Finally, outlet water quality deteriorates and exceeds emission standards of the State, and causes decisive unfavorable impact upon water environment and ecological system. (4) Risk and Accident in Normal Operation Due to the suddenness of risk and accident of wastewater treatment system, it may bring vital damage to the personnel maintaining the system and even endanger their lives. In case of environmental risk and accident, the health and safety of the working personnel in wastewater disposal plant are firstly influenced. In case of accident of one construction of wastewater system, the accident must be immediately eliminated. In this case, repair workers should enter wastewater pipe, inlet well or wastewater basin, where poisonous H2S gas tends to exist and accumulate and with no protective measures, repair personnel may breathe in poisonous gas due to bad ventilation and suffer from symptoms such as swirl, unsmooth breath and death in serious case. The wastewater or sludge contains various pathogeny bacteria and helminth eggs. In direct touch with wastewater or sludge, operators may suffer from some intestines diseases and verminosis if sanitation conditions are terrible. 6.2.2 Prevention Countermeasure and Measures of Risk and Accident 6.2.2.1 Prevention Countermeasure of Source Accident Source accident means if the production of enterprise producing wastewater is consecutive, outlet water quality is stable and pretreatment device on the site runs smoothly. The abnormal emission of individual enterprise may cause sharp increase of relevant wastewater concentration and finally influence stable operation of wastewater disposal plant. Therefore, source enterprise should notify wastewater disposal plant timely in the construction start, in order to take some measures. Production limit or shutdown proposal should be implemented for a plant with accident if necessary, for reducing the load and environment risk of wastewater disposal plant.

y� Carry out technical treatment for the reason of abnormal emission, add nutritional substance to aerobiosis basin in case of swelling trend of sludge for improving the properties of the sludge, and strictly control the air quantity of van so as to resolve the swelling problem of sludge on very start.

y� Control the quality of the wastewater of the pipe-connected enterprises, and carry out strict inspection and monitoring of the quality of wastewater, and control water quality in anaerobic hydrolysis basin according to the load design, and ensure the normal operation of anaerobic hydrolysis basin.

y� Clean production should be taken for reducing the arbitrary emission of stench. Production source of stench is to be regularly eliminated. Strengthen the adjustment of gas capacity of aeration basin for reducing arbitrary emission of stench.

6.2.2.2 Accident Countermeasure & Measure of Wastewater Disposal Plant Itself

The accident of wastewater disposal plant itself comes from equipment failure, overhaul or change of process parameter, which deteriorates the efficiency of treatment. With serious water pollution, an accident should be prevented and some emergency measures be prepared.

y� To enable wastewater disposal plant to restore production in the accident status rapidly, main buildings should be provided with relevant buffer capacity and the equipment (e.g. backflow pump, backflow pipe, valve and instrument).

y� Top quality equipments are selected. Top-quality products with low failure rate and easy maintenance should be selected as various machines, instruments and other equipments of wastewater disposal plant. Key equipments should run with one in standby. Wearing parts should be prepared for timely renewal in case of accident.

y� Strengthen the monitoring and control of accident symptom, carry out regular patrol inspection, adjustment, maintenance and repair. Timely find out the symptoms that may cause accident, and eliminate potential accident.

y� Strictly control the process parameters of various disposal units such as water quantity, water quality, residence time and load strength, and ensure the stability of treatment effect. Provide some automatic water flow and quality analyzing and monitoring instruments, and carry out regular sampling and determination. The operators should timely adjust and keep the equipment in good status.

y� To strengthen technical management work of wastewater disposal plant, and improve the treatment efficiency of different process segments are main items of the work for ensuring qualified emission. Wastewater disposal plant shall try to import talents proficient in wastewater treatment technique and management, and meet technical demand of the plant and realize scientific and regularized management. The managerial staff of wastewater disposal plant should have high technical level and management capability. Main operators should have strict trainings on theory and practical operation before work start.

y� Strengthen the operating management and the monitoring of inlet and outlet water. Prohibit any discharge of unqualified wastewater before treatment.

y� Rainwater pipeline outlet and wastewater outlet should be equipped with cut-off control valve. Turn off the valve in case of accident so as to timely hold back the wastewater and prevent the direct entrance of wastewater into water system.

6.2.2.3 Emergency Handling Proposal for Risk and Accident (1) Classification and Organizational Structure of Emergency Handling Proposal In case of accidental emission of the wastewater, the leadership group of the plant for emergency rescue should make judgment on the impact and damage of the accident according to the accident information from the duty room of the emergency rescue command center. For an average accident, only Class-III emergency rescue can be actuated. The head of plant on duty, the person on duty on the site and technical operator should establish a Class-III emergency team for carrying out the rescue action. For large-scale accident with serious damage, the leadership group of the plant for emergency rescue should rapidly set up a field emergency rescue command center comprising the director and deputy director of the wastewater plant and technical, instrument and equipment engineers. According to the demands of rescue on the site of the accident, on the basis of part-time rescue workers of the plant, special teams e.g. rescue, medical service, security guard, communication & information release should be set up and mobilized for emergency rescue action. According to the harm of an accident and emergency rescue required, the emergency rescue actions are divided into three classes: Class-III emergency (early warning emergency, for average accident), Class-II emergency (field emergency, for big accident) and Class-I emergency (overall emergency, for major accident).

y� Class-III emergency: in case of controllable abnormal event or sudden event to be easily controlled e.g. small-size wastewater leakage, and equipment failure, wastewater plant carries out emergency actions such as leakage stopping, medical service, repair and rescue according to the preset procedures;

y� Class-II emergency: in case of any large-size wastewater leakage, sharp increase of pollutant concentration of inlet water and power cut-off of wastewater plant, the harm and impact of the accident exceed the handling capability of Class-III emergency rescue and need the whole emergency rescue force of the plant for disposal;

y� Class-I emergency: the impact of an accident goes outside the bound of wastewater plant and requires the leadership institution of the plant for emergency rescue to coordinate

surrounding enterprise or surrounding emergency rescue authorities for obtaining the support of social rescue force and organizing the traffic control, and withdrawal and evacuation of the pedestrians nearby and the support of rescue team, for the purpose of minimizing the personal death, economic loss and social impact of the accident.

The organizational institutions of emergency handling for Class I, II & III are included in Figure 6.2-1-6.2-3.

information of safety monitoring system. The leadership for emergency rescue should determine the actuation of emergency handling proposal according to the scale of accident. In case of grave sudden environment pollution accident in the plant area, the emergency rescue command center will directly contact local government, environmental protection department and fire prevention authorities for alarm, and request information and technical supports.

(3) Emergency Handling Measures Both rainwater pipeline outlet and wastewater discharge outlet are equipped with cut-off control valves. Immediately turn off the valve, and timely cut off the wastewater and prevent the wastewater from directly flowing into the water system in case of accident. In case that the wastewater flows into reception water system i.e. Xibei Canal due to the untimely cut-off of the valve, local governments and environmental protection authorities at district or municipal level should be timely notified. The government will run as temporary rescue headquarters and command the production shutdown of various wastewater pipe-connected enterprises; and the environmental protection authorities will set up emergency rescue team and build up cofferdam for blocking up outlet of wastewater disposal plant immediately. Moreover, monitoring personnel should be sent out for immediate monitoring of pollution belt from the outlet of tail water to 2km lower reach of Xibei Canal and analyzing the water quality parameters of the water system according to the standards. 6.3 Artificial Wetland Works of Wuliangsuhai Lake 6.3.1 Analysis of Wetland Operation in Winter 6.3.1.1 Extended Wetland System in High and Cold Conditions The inlet water of Wuliangsuhai Lake has the features as follows: large water volume, low organic substance content, bad biochemical properties and high nutrient salt content. Such inlet water makes traditional anaerobic pond and facultative pond hardly realitze their desirable functions. Especially in cold area in winter where the water surface is frozen traditional, the stabilization pond usually lost its designed function but only plays the role of water storage (such as the stabilization pond of Kelamayi Municipality, Xinjiang). Wuliangsuhai Lake has high inlet water flow in winter. It’s calculated that present wetland area isn’t adequate in storage. Moreover, in frozen period, the pollutants especially nitrogen & phosphor salt in the inlet water is huge in quantity. Therefore, nutrient removal efficiency of wetland in winter should be guaranteed. The survey of the departments of US on best management practice (BMPs) of wetland in cold climate indicates that some special considerations are required for the design and operation of wetland in frozen and snow blanket conditions. This is because: in frozen condition, the depth and volume of water system will decline at least by half, and the frozen earth layer of the surface of wetland is nearly water resistant; water forcedly flows through water system and erodes substrate sludge; DO declines, and water quality problem appears; and processing efficiency declines sharply. Moreover, the inflow water in the wetland has bad water quality and requires special treatment. Figure 5.1 includes the change of water flow and substrate sludge in frozen condition.

Figure 9.1-1 Change of Water Flow and Substrate Sludge in Frozen Conditions For shallow-water wetland (swamp), the ice layer of Wuliangsuhai Lake can reach the thickness of 0.6-1.0 m, and is frozen by and large, where water is unable to flow. Therefore, it is can be used under the

cold condition. Pond and wetland system can be applicable after renovation. In light of frozen condition in winter, extended pool expands its depth and volume. Adequate flowing water layer is available under the ice cover. The wastewater treatment in ice cover condition is applicable. Generally, the minimum extended storage capacity is no less than 25%, and extended pool should have 50% storage capacity at least. Moreover, ice cover makes extremely low content of dissolved oxygen in lower layer of water system. Aeration & re-oxygenation measures can be taken for promoting the biological decomposing and transformation of microbes. The comparison of different wetland systems is included in Table 6.3-1. Table 6.3-1 Comparison of Different Wetland Systems in Cold Condition

With expanded water depth & storage volume, the extended pool system has the characteristics of anaerobic pond and facultative pond. Moreover, the aeration and re-aeration in proper areas can not only improve the pollutant removal efficiency of organic substance but also facilitate nitration and denitrification of nitrogen and phosphor dilution and absorption. Extended pool in cold area has the advantages as follows: (1) good water head preservation, lower layer with good over-wintering capability under the impact of ice cover; (2) long residence time of water, good pollutant removal capability; (3) deep facultative pond is able to reduce the movement of oxygen; (4) the multi-level small while deep ponds has low SS concentration in the outlet water; (5) deep pond facilitates the substrate sludge to become denser; and, (6) flexible operation. Wuliangsuhai Lake is frozen in November and melt in March of next year with ice cover period of over four months. In this period, total emission of pollutants is huge. The calculation results of water quality and quantity data in May 2008- April 2009 reveal that in five months from December to April, the emissions of organic substance, ammonia nitrogen, total nitrogen and total phosphorus are 0.6, 2.4, 1.1 and 1.5 times of the total in other months respectively. 6.3.1.2 Uncertainities of pollutants removal and Mitigation Measures Artificial wetland usually has very bad pollutant removal capacity in winter. Because the cold weather will not only reduce the bacteria activity, but also eliminate the plants’ function in oxygen accumulation around their rooy system which is the primary function of wetlands to remove pollutants. However there are many proven technologies to improving the pollutants removal efficiency in harsh winter. Among them, a combination of the “ice layer-air layer” thermal insulation technique and oxygen adding technology has been proven the least cost while achieving the desirable effects of removing pollutants. For example, in Figure 9.1.2, when ice layer takes shape in some thickness in winter, the water lifting pump station is started, and the operating water level of wetland declines by about 10-20cm for realizing the purpose of preventing the heat dissipation of water system and improving the velocity of biochemical reaction of microbes. The study proves that the aeration in front or back of wetland system can obviously improve dissolved oxygen concentration in wetland, shock-load resistence capability of the system and pollutant removal efficiency of organic substance by over 10%. The removal efficiency of NH4

+-N and TN is obviously improved by up to about 60%. Relevant studies prove that artificial aeration measures play obvious role in improving wastewater treatment effect in winter. J. Nivala holds that in winter, aeration measure

and thermal insulating measure can realize best treatment effect if applied together, where the removal rate of BOD, COD and NH4

+-N reaches up to 88%, 44% and 93% respectively. An under-ice aeration device can be set up in Wuliangsuhai Lake wetland for improving the pollutant removal efficiency especially in frozen period in winter. Under-ice aeration technique can be used according to local condition.

Figure 6.3.2 Schematic Diagram of Ice Layer-Air Layer Thermal Insulation and Under-ice Aeration 6.3.1.3 Wetland Plant Configuration In small lake-area of Wuliangsuhai Lake, reed is outstanding variety and plays a dominant role. Existing reed can be directly used as the wetland plant, instead of more expensive new species of plants. To improve the tourism value in respect of landscape, a series of landscape plants can be configured. Wetland renovation needs higher water level in operation. The water level should be controlled for realizing optimal pollutant eliminating water depth and maintaining the growth of reed. According to the results of observations on three sampling points of Wuliangsuhai Lake at 37 times, the distribution of reed at water depth of 0-0.5m, 0.5-1.0m and 1-1.5m is 19%, 35% & 36% respectively, with an average of 0.91+0.13 m (95% reliable scope). It proves that reed isn’t fit for the area with 0-0.5m water depth, and most reeds are fit for water depth of 0.5-1.0m. Therefore, the water depth of wetland should be controlled at 0.5-1.0m. 6.3.1.4 Flow Scheme of Extended Wetland System The schematic diagram of the section of compound wetland is included in Figure 6.3-.3.

Figure 6.3-3 Schematic Diagram of the Section of Compound Wetland System 6.3.2 Inlet Water Quantity of Wetland in Winter and Water Quality Analysis 6.3.2.1 Water Quantity Analysis

In winter, among three wetlands, only the general trunk canal wetland runs. Figure 6.3-4 presents the monthly quantity change of water that Liufenqiao of general trunk canal discharged into Wuliangsuhai Lake in 1996-2005. Figure 6.3-5 presents monthly quantity change of water that Honggebo Water Lifting Station of general trunk ditch discharged into Wuliangsuhai Lake in May 2008-April 2009. Due to the impact of irrigation water consumption of Hetao Irrigation Area, the water quantity of the general trunk ditch features obvious monthly change. The statistics on water quantity in the following two charts reveals that the change of water quantity can be roughly divided into three stages. In irrigation period of May-September, the quantity of water discharge is huge. From June 2008 to September 2009, the quantity of discharge remains at 49.50-66.48 million m3 monthly by and large; it’s highest in October (less in October 2008) and November, and reaches up to 119 million m3 in November 2008, accounting for nearly 24% of the total discharge of general trunk ditch; and in non-irrigation period from December to April, the quantity of discharge is least and about 10 million m3

monthly.

The table proves that pollutant concentration of the water has obvious seasonal change. The months with obvious concentration increase are December to April of next year mainly (where December is the transitional month from low pollutant concentration to high): CODCr concentration is 86.5-186 mg·L-1, with an average of 135.3 mg·L-1; ammonia nitrogen concentration is 8.7-35.6 mg·L-1, with an average of 22.5 mg·L-1; TN concentration is 12.35-36.9 mg·L-

The calculation results of water quality and quantity data in May 2008- April 2009 reveal that in five months from December to April, the emissions of organic substance, ammonia nitrogen, total nitrogen and total phosphorus are 0.6, 2.4, 1.1 and 1.5 times of the total in other months respectively. 6.3.3 Accident analysis on Abnormal Operation 6.3.3.1 Risk Accident Simulation According to the identification of risk source of this project, inlet water is directly discharged with no treatment when wetland doesn’t run. According to the inlet water quantity and quality analysis of wetland, there’re two cases: the 1st is non-freezing period, and the 2nd is freezing period. 1)Risk Analysis Model Hydraulic mathematical model has 0D, 1D, 2D & 3D equations. 0D model is used for water quality prediction in most simple and ideal status. 1D model is used in average flow parameter of a section, takes into account the change of parameters along the vertical direction. 2D model not only has the features of 1D model but also considers the change of parameters along the horizontal direction. 3D model using “point” flow parameter takes into account the change of parameters not only along the vertical and horizontal directions but also the perpendicular direction. Obviously, 3D model is much more complicated than other models.

When the ratio between wastewater and clean water is 1:10 or over 1:20, only dilution instead of decomposing is considered. Completely uniform mixture is realized within the section. In this case, the issue is 0D. The daily inlet water of wetland is 0.333-2.116 million m3, much less than water quantity of the whole sea area. Therefore, 0D hydraulic mathematical model is selected. 2) Zero- dimention Basic Hydraulic Equation If we treats one water body such as one river, one reservoir, lake or water area as complete system, various water masses in the system are completely mixed evenly. The substance flowing into the system is immediately scattered in the whole system. This closed consecutive flow & completely mixed reaction system is an ideal status. The following mass balance relationship under the mass conservation principle is (Figure 6.3-6)

Where Q is flow amount, m3 s-1. After wastewater enters the river, pollutants are completely uniformly mixed on the section when inlet water from upper reach isn’t equal to zero. Pollutant indicator value no matter dissolved status, particle status or total concentration can be derived under node balance principle. The node balance principle includes node mass balance and water quantity balance i.e. the sum of inlet water quantity and mass of the node equal to the sum of outlet water quantity and mass of the node.

Due to linear overlay of pollution source functions, the emission impact of more than one pollution source on node is equal to a sum of individual impacts of various pollution sources. This complies with the linear overlay relationship. 6.3.3.2 Predictions on the Result of Risk and Accident 1) Prediction on the Result of Risk and Accident in Winter The wetland system of general trunk ditch annually discharges 424 million m3 water into Wuliangsuhai Lake, including 63.6 million m3 in winter, accounting for 15% of the total. In case of risk and accident, untreated wastewater is directly discharged into Wuliangsuhai Lake through rubber dam, with discharge amount of 5 million m3, with CODCr concentration of 112.7mg/L, NH3-N concentration of 18.9mg/L, TN concentration of 21.6 mg/L and TP concentration of 3.86 mg/L(9.2-1). The water

storage capacity of Wuliangsuhai Lake is 360 million m3, with CODCr concentration of 67.1mg/L, NH3-N concentration of 15.9mg/L, TN concentration of 19.9 mg/L, TP concentration of 0.77 mg/L (5.2-1). If the above-said values are used in the formula 9.3-3, the concentrations of CODCr, NH3-N, TN and TP are 67.7 mg/L, 15.94mg/L, 19.92 mg/L and 0.81 mg/L respectively. Obviously, leakage has no decisive impact upon the water quality of sea area. 2) Prediction on the Result of Risk and Accident in Summer The wetland system of general trunk ditch annually discharges 424 million m3 water into Wuliangsuhai Lake including 2756 million m3 in summer, accounting for 65% of the total. In case of risk and accident, untreated wastewater is directly discharged into Wuliangsuhai Lake through rubber dam, with discharge amount of 10 million m3 with CODCr concentration of 73.2mg/L, NH3-N concentration of 8.82mg/L, TN concentration of 13.94 mg/L and TP concentration of 1.034 mg/L(9.2-1) . The water storage capacity of Wuliangsuhai Lake is 560 million m3, with CODCr concentration of 38.1mg/L, NH3-N concentration of 0.955mg/L, TN concentration of 2.83 mg/L, and TP concentration of 0.098 mg/L (5.2-1) . If the above-said values are used in the formula 9.3-3, the concentrations of CODCr, NH3, TN & TP are 38.4 mg/L, 1.06mg/L, 2.94 mg/L & 0.106 mg/L respectively. Obviously, leakage has no decisive impact upon the water quality of sea area.

Maintain the water resource utilization current situation, and waste water treatment current situation and land utilization current situation of processing park, and avoid various impacts of construction period and operation period in plan 1.

and construction of project meets the requirement of common people.

Disadvantages

1. Minor dust, waste water, noise, and solid waste, etc., generated during construction period shall destroy the ground surface vegetation and incur soil erosion; it temporarily increases the transport pressure and destroys the landscape of construction site; 2. Water reclamation plant, waste water treatment plant and pump room, etc. permanently occupy part land, and change the utilization mode for such land. The pollutant as waste water, noise, offensive odor and sludge, etc., during run of intended project construction shall incur certain impact to environment in the circumference; 2. Improve the treatment cost of water supply and wastewater, increase the outlay of water consumption of enterprise;

1. With the industrial development of Bayannaoer City, the wastewater quantity is increasing, a large number of wastewater without treatment shall be directly discharged into the ground surface water system, the pollution of water system shall be worsened continually, and it shall impact the living quality of residents and sustainable development of economy. 2. The treatment rate of industrial wastewater is far below the environment protection requirement of China, and this seriously restricts the economic development of Bayannaoer City; 3. The groundwater is exploited greatly, the level of groundwater is continually decreased, forming underground funnel. If this situation is continued for a long term, in the future there shall have no water for exploitation, water environment quality shall be further worsened, and this shall impact the residential environment of residents in the circumference of drainage area. 4. The worsening of water quality of water environment of Wuliansu Lake is speeded up, paludification process is speeded up, wetland function disappears, and destruction speed of ecological environment is speeded up, and this threats the safety of water environment of Huanghe River. 5. It does not meet the requirement of general planning.

According to table 7.2-1, after execution of plan 1, although it shall incur certain environmental impact during construction and operation of this project, these impacts are limited by time and space aspects, through various measures the impact can be eliminated or reduced to the greatest extent, and shall not incur unfavorable impact of large area to regional environment, furthermore, execution of plan 1 can change the current situation of pollution of water environment of Bayannaoer City, comprehensively dispatch and distribute the water resource, improve regional ecological environment, improve the living environment quality of people, promote the sustainable development of Bayannaoer City, and this also meets the requirement of vast common people. Thus plan 1 is deemed as reasonable during this appraisal. 7.3 Comparison, selection and analysis on alternatives of reclaimed water supply project 7.3.1Comparison, selection and analysis on restoration process of reclaimed water supply project The process of reclaimed water is generally fairly matured. Under precondition of ensuring quality of effluent water, following two water treatment process plans are selected to carry out comparison, selection and analysis thereof:

y� Plan 1. General treatment process flow:

Raw water coagulating settling filtering sterilization y� Plan 2. Membrane treatment process flow: Raw water micro pore filtering sterilization

According to process flow charts of two plans it can be seen that, the difference of two plans is that, the selection of main process is different. In plan 1 it adopts the three section treatment process of flocculation, settling, filtering, and sterilization, while in plan 2, it adopts the membrane technology. The following is comparison on difference of two processes. 7.3.1.1 Comparison on technology The flocculation, settling and filtering process can ensure the supply of qualified treating water in the whole year, since the settling basin relieve the burden of filtering basin, even the water quality is worst in winter, the filtering basin can also be of normal run, the filtering period is over 10 hours, and the quality of treating water can reach the stated water quality requirement. The process is also the main reclaimed water treatment process widely utilized in domestic and abroad, considering of low temperature of winter in local region, the treatment effects of flocculation, settling, filtering and sterilization (old three sections) are compared, and the details are shown in Table 7.3-1.

Fig. 7.3-1 Sketch of membrane treatment technology

CMF membrane is one of the micro filtration membranes; it is the hollow fiber with outer diameter of 550 and inner diameter of 300 . The wall of hollow fiber is composed of multi-pore materials, the pore size is all below 0.2 , and area of pore accounts for over 70% of fiber wall. The water without containing foreign substance can easily penetrate the CMF fiber wall, and it only needs the work pressure of 20kPa (2m water head). When the water containing foreign substance runs through the MF hollow fiber membrane from outside to inside, the particle over 0.2 is 100% captured in the outer surface of membrane, and the one less than 0.2 is also captured by different proportions, and its work pressure is between 40�100KPa. During work of CMF membrane, the captured foreign substance particles shall gradually accumulate on the outer surface of hollow fiber, the pore is also gradually covered, the resistance over the water gradually rises. In order to timely eliminate the foreign substances captured, and reduce the resistance over the water, the hollow fiber needs to be timely back flushed by cleaned air. The work status and back flush status are shown in Fig. 7.3-2.

Water after filtration

Water before filtration Air Captured foreign substance Eliminated foreign substance Fig. 7.3-2 Work status and back flush status sketch After each time back flush of air, the work pressure of membrane shall not completely restore to its original status, and work pressure shall gradually rise. The rising of this pressure is caused by the organic matter and scale formation attached on the membrane surface, when pressure rises to certain value, it needs to carry out chemical purge to surface of membrane, so as to eliminate the organic matter, Fe and calcium scaling. The indicators as strong bacteria elimination, water quality perception, and hygiene, etc., of this process are superior to traditional process. Nevertheless, it has a lot of one time investment with fairly high run cost, and it shall basically not improve the indicators as soluble total solid, total hardness, total alkalinity, etc. Generally it is reused for residential quarters or pretreatment of reverse osmosis and it is the rising and new technology of China at present. 7.3.1.2 Comparison on economy Economies of plan 1 and plan 2 are compared, details refer to table 7.3-2.

According to comparison on technology and economy as above mentioned, it is know that in plan 1 it has fairly good treatment effect, it can ensure the water quality of reclaimed water with a little higher investment, in plan 2 the treating water quality is good, but the investment and operation cost are both too high. According to requirement of effluent water of reclaimed water supply work of this project, mainly applying the process flow of plan 1 can meet the requirement. As above mentioned, the process flow of plan 1 is to adopt the process of coagulating, settling, filtering and sterilization as the main treatment of reclaimed water supply works. According to water consumption requirements of enterprises of the processing park, the reverse osmosis process unit may be added appropriately. This process is featured by stable and reliable treatment effect, appropriate investment and fairly low cost, and the process flow of this project finally determined is shown in 7.3-3.

Fig. 7.3-3 Sketch of reclaimed water treatment process

7.3.2 Comparison, selection and analysis on process plans of reclaimed water supply project (1) Flocculation basin Grid flocculation basin is the new type system developed in recent years with application of turbulent flow theory, its plane layout is similar to perforated swirling flow flocculation basin and is in series connected by multiple grids of vertical shafts. The flocculation basin is divided to square grids with same or similar areas. The flow sequence of influent water is from the first grid to the next one, and the flow is alternated from up to down opposite angles up to the outlet. In the grids accounting for 2/3 of the whole basin, the grid is setup via the vertical water flow direction, when it passes through the grid pore, the water current is narrowed, after passing through the mesh the water current is enlarged, constituting good flocculation condition, and thus it can decrease the addition quantity of flocculation reagent and shorten the flocculation time. The grid flocculation basin has good effect and little loss of water head, flocculation time is fairly short. The disadvantage is that, it has the sludge accumulated in the end basin bottom. Bent plate flocculation basin is a new type and high efficiency flocculation facilities developed in 1980s. The bent plate flocculation basin is to adopt the bent plate placed in the flocculation basin, thus water current flows up and down between the bent plates in-series connection. Relying on the partial eddy flow generated by turning, narrowing and enlargement, the collision opportunity of particles in the water current is increased, thus the fairly even energy consumption can be obtained along the way, so as to constitute fairly ideal flocculation process. The bent plate flocculation basin has the high utilization efficiency of energy, and short flocculation time, nevertheless its availability to raw water with fairly great change of water quality and water quantity shall be fairly bad. After comparison on advantages/disadvantages of above two basin types, the grid flocculation basin is finally selected as the design basin type of reclaimed water supply works of this project. (2) Settling basin Horizontal flow settling basin has fairly wide application, and is especially utilized in the water plant of urban area. The horizontal flow settling basin is the rectangular one, the upper part is settling area and the lower part is sludge area, the front area of basin is influent water area, and the rear part of the basin is the effluent water area, after coagulating, the raw water flows into the settling basin, and is then evenly distributed in the whole section of influent water area, it enters the settling area and slowly flows into the outlet area. The particle in the water settles in the basin bottom, the accumulated sludge is continually or periodically discharged outside the basin. It has the advantages of simple structure, shallow basin depth, convenient operation and maintenance, and strong adaptability to water quality and water quantity of raw water, low consumption of drug and energy, and convenience of sludge discharge, etc., in the big and middle level water plants it is widely utilized. The disadvantage is that, the land occupancy is too great.

The slope plate settling basin is the one developed on the basis of shallow basin theory. Various slope plates forming certain angle with horizontal plane are placed in the settling basin, the water flows from downward to upward, and the particles settle in the bottom of slope plate. When particles accumulated reach certain level, they shall automatically slide down. The advantage of slope plate settling basin is that, the settling efficiency is high, the volume is small, and the land occupancy area is small. The disadvantage is that, the anti-impact capacity is inferior to that of horizontal flow settling basin, with more material consumption and higher cost. After comparison on advantages/disadvantages of above two basin types, the slope plate settling basin is finally selected as the design basin type of this project. (3) Filtration basin The four valves filtration basin is the traditional one of filtering process of water cleaning plant, till now it has over 100 years history, nevertheless it is also one of the basin types with widest application till now. Its characteristic is that, it has stable work status, good quality of effluent water, matured run experience, its operation is stable and reliable, and it adopts the programmable controller to realize the one-step operation; The shortcoming of the four valves filtration basin is that, the basin volume is fairly great, the back flush water consumption is fairly great with more inlet and outlet water valves and great work volume of maintenance. Adopting electrical valve can realize the one-step automatic operation, but it cannot finely adjust the openness of outlet water valve and control the filtering speed of filtration basin. V type filtration basin is a new type one, and its advantage is that, the filtering period is long, the fairly coarse and thick filtering material layer has high utilization rate, the filtering speed is fairly high, and the water quality after filtering is good, with the utilization of air-water back wash, the back wash effect is good with minor water consumption. According to variation of water level of filtration basin, the openness of outlet water valve can be finely adjusted, so as to reach the purpose of controlling filtering speed of filtration basin. V filtration basin also has the advantages of good quality of effluent water and fairly small volume of filtration basin. Its shortcoming is that, it has fairly high automatic control requirement, with more back wash equipments and fairly higher cost. After comparing the advantages and disadvantages of above two basin types, finally the V type filtration basin is selected for this design of this project. 7.3.3 Selection of sterilization mode The microorganisms in the water are mostly attached on the suspended particles, after treatment of coagulating, settling and filtering, the bacteria and virus in the water can be greatly eliminated. Nevertheless, in order to ensure the bacteriology indicator of drinking water, the sterilization process is necessary. The sterilization treatment of water is usually the last work sequence of drinking water treatment. The purpose of sterilization is to eliminate the hazard pathogenic microbe (pathogenic bacteria, virus, etc.) in the water, and prevent from the hazard of waterborne infection. It consists of chemical method and physical method, the chemical method is to add chemical agent in the water, such as chlorine, ozone, heavy metal and other oxidizing agent, etc. The physical method is to carry out heating sterilization and ultraviolet ray sterilization, etc., instead of adding drug agent in the water. The comparison on properties of various disinfectants is shown in Table 7.3-3. Table 7.3-3 Comparison on property of disinfectant

Appropriate condition

Most water plants adopt chlorine sterilization, and bleaching powder is only applicable to small water plant.

When it has a lot of organic substances in the raw water, and the water supply pipeline is fairly long, it is appropriate to adopt chloramines sterilization.

It is appropriate for organic substance, for example, when the phenol pollution is serious, it shall be prepared at site, and directly utilized.

The water treatment cost is high, and it is appropriate for the serious pollution of organic substance. Since it does not have continual sterilization effect, in the water of inlet pipe network, minor chlorine shall be added for sterilization.

In the pipeline it does not have continual sterilization effect. It is appropriate for water treatment of centralized users as industrial and mining enterprises, etc.

According to above comparison and analysis, and considering of economy, practicality and environmental impact, etc., the reclaimed water supply works of this project adopt the chlorine dioxide for sterilization. 7.3.4 Comparison and selection on sludge treatment plans of reclaimed water supply works 1) Selection on thickening and dewatering of sludge Solid content of discharged sludge water of the settling basin of water plant is usually only 0.2�1.0%, the sludge volume shall be reduced after thickening thereof, and then the thickened sludge shall be sent to subsequent process to carry out dewatering of sludge. Usually it is required that solid content of thickened sludge shall be over 3%, so as to meet the requirement of the dehydrator for high efficiency dewatering of sludge. The general sludge thickening and dewatering contains two modes of gravity thickening/mechanical thickening, and mechanical thickening/ mechanical hydration. The gravity thickening is essentially a settling process and belongs to compression settling. Prior to thickening, concentration of sludge is fairly high with mutual contact and support among the particles. After thickening process is started, under the gravity effect of the particles of upper layer, the water in the clearance of the particles of lower layer is extruded from the interface, and congestion of particles is closer. Through the congestion and compression process, the concentration of sludge is further improved, so as to realize the sludge thickening. The advantage of the gravity thickening and mechanical dewatering mode is that, the thickening basin greatly reduces the volume of the sludge in need of hydration, and effectively decreases the number of dehydrators, the equipment investment is greatly saved, the power consumption is lowered, the concentration of dehydrated sludge is fairly even, and dehydrator operation is stable. Its shortcoming is that, it needs to build up the thickening basin, the civil cost is fairly high, and land occupancy area is fairly great. While the mechanical thickening and mechanical dewatering mode is just the other way, the thickening basin can be cancelled to save the land utilization

area, reduce civil cost, nevertheless, since the sludge number in need of dewatering is great with low and uneven concentrations, the treatment capacities of thickening and dewatering equipments are decreased, the number is increased, and thus the equipment cost is greatly increased, with increase of power consumption, and the solid content of the sludge cake is not stable. As above mentioned, the technology of gravity thickening and mechanical dewatering is superior to mechanical thickening and mechanical dewatering mode. Civil cost of gravity thickening and mechanical dewatering is fairly high but equipment cost fairly low, its total cost is lower than that of the mechanical thickening and mechanical dewatering, although gravity thickening increases the land occupancy area, in this project the high concentration thickening basin is adopted to improve the effective settling area of the thickening basin, this saves the land utilization without additional requisition of land. In this project, it intends to adopt the gravity thickening and mechanical dewatering mode to carry out thickening and dewatering treatment of sludge. 2) Basic structure and characteristic of sludge dewatering equipment At present it mainly adopts three types of sludge dewatering machines as plate-and-frame press filter, centrifugal dehydrator and Band type press filter. The basic characteristics of three types of sludge dewatering equipments are respectively briefed as below: a. Plate-and-frame press filter

Plate-and-frame press filter is the pressurization and filtering equipment of clearance operation and is widely utilized in the sectors of sugar making, pharmacy, chemical industry, dyeing, metallurgy, coal washing, food and water treatment, the solid and liquid are separated via the filtering mode, and this is a large/middle separator with fairly wide adaptability for materials. Box type press filter has fairly low requirement to solid content of the incoming sludge, and 2%-3% shall usually be appropriate, while the solid content of outgoing sludge is higher than that of band type press filter and centrifugal dehydrator, the run process is the intermittent process of periodic operation of pump-in, pressing and filtering of sludge, and elimination of sludge. Its shortcoming is that, the continual operation is not available, according to blocking situation of filtering board, the filter cloth needs to be washed by one time after certain run period, the filtering board or rubber diaphragm are easy of damage and need to be frequently replaced, and the equipment volume is large with high price.

b. Centrifugal dehydrator

Horizontal spiral sludge dehydrator is a complete set of unit consisting of principal machine and auxiliaries. The unit is full closeness structure without leakage and is available for continual run of 24 hours, its main structure characteristic is that, it adopts fairly large length-to-diameter factor to extend the staying time of material and improve the elimination rate of solid substance. It adopts the exclusive spiral structure to reinforce the extrusion strength of spire upon the sludge cake, and improve the solid content of solid cake. It adopts the advanced dynamic balance technology to reduce the vibration; it adopts the unique differential rotation speed regulation technology to increase the discharge torsion moment of spire and load capacity. The centrifugal equipment has high efficiency, small land occupancy, the environment of machine room is clean, the complete set of unit adopts the advanced automatic integration and control technology, the rotation speed and differential rotation speed are stepless and adjustable. It has the safety protection and automatic alarm devices, and its run is stable and reliable. The main shortcoming is that, the noise is great, power consumption is high, the rotation blade, etc., has high requirement of wearing resistance, the requirement for quality of manufacturing material and processing accuracy is rigid, and the price is expensive.

c. Band type press filter

Band type press filter is a high efficiency solid and liquid separation equipment, and its theory is that, the sludge after flocculation is repeatedly extruded and compressed through the varied-direction bend between the roller systems, and tension effect of filter band, shear force is generated accordingly and thus there is a relative displacement for the sludge particles, and the free water and capillary water in the sludge are separated to obtain the sludge cake with fairly high solid content, so as to realize the dewatering of sludge. Its characteristic is that, it has high

dewatering efficiency, great treatment capacity, continual filtering, stable property, simple operation, small volume, and small area of land occupancy. The treatment capacity of band press filter is determined by the band speed and filter band tension of dehydrator, and dewatering property of sludge, while the band speed tension is also determined by the dehydrating effect required. Its disadvantage is that, when the incoming sludge quantity is too great, or solid load is too high, it shall lower the dehydrating effect. The homemade band dehydrator usually has fairly small treatment capacity, sludge solid load is only 150�250kg/m·h, and treatment capacity of imported high quality band dehydrator can be up to 250�400kg/m·h.

3) Type selection of sludge dewatering equipment The above three sludge dehydrators have their own advantages and disadvantages, during type selection it shall combine with project scale, site condition, management level, and capital condition, etc., and mainly take into account the reliability of equipment run, automatic degree of system, dehydrating effect of sludge, building investment and treatment cost, etc., for reasonable selection of equipment type. Comparison on property of several common dehydrators is shown in Table 7.3-4. Table 7.3-4 Comparison on properties of general dehydrators

The efficiency of sludge dewatering is directly related to selection of dehydrating equipment, etc., the detailed selection of dehydrator type shall be reasonably made after generally analyzing and determining the factors of technology, economy, environment and management, etc., according to characteristics of sludge and site condition. The result of comparison and analysis on part configuration of dehydrator equipment, solid content requirement of incoming sludge, solid content concentration of dehydrated sludge, run status, operation environment, land occupancy of dehydrator, flush water quantity, and replacement of wearing parts during actual run of equipment, etc., shows that the discharged sludge of water plant has the characteristics of relatively low solid content of compressed and dense sludge, and fairly fine particle size of sludge, etc., among three machine types, price for plate and frame machine is highest, and in turn is centrifugal dehydrator and band dehydrator. According to treatment situation of sludge of water plant of China at present, and due to the consideration of economic power of Bayannaoer City, band dehydrator is herein recommended. 7.3.5 Comparison and selection of pipe material Selection of pipe material has great impact to water supply quality, project cost and water supply safety, thus it is very critical to select the pipe material, hereinafter is the comparison on characteristics and properties of various pipe materials. At present, the transportation and distribution water pipes generally utilized in domestic and abroad mainly consist of steel pipe (SP), ductile iron pipe(DIP), glass-reinforced plastic pipe(RPMP), prestressed steel concrete pipe(PCP), prestressed concrete cylinder pipe(PCCP), etc. Various pipe materials have different characteristics: (1) spiral-seam submerged-arc steel pipe (SP)

SP has fairly good mechanical strength, and has great advantage in the aspects of anti-bend, anti-tension, toughness, impact resistance, and anti-vibration, etc., and can withstand the fairly high internal pressure and appropriate external pressure. According to operation requirement it can be machined to different sizes, different bores and different wall thicknesses, the joint forms are diversified, the holding and jointing are convenient with great flexibility, and the construction is easy. Nevertheless, its inner wall is easy of incurring scaling and impacts the water quality. The internal insulation must be done well, such as cement liner. The biggest shortcoming of SP is its bad anti-corrosion property, if the internal and external insulation and electrochemistry protection is not perfect, the service life shall be fairly short (20 years). The toughness of steel pipe is fairly great, at present, after general cement coating and lining, the n value of roughness coefficient is usually considered as 0.013 (manning formula) for design. SP pipe has good mechanical strength and is available for machining, thus it has great advantage when the geological condition is bad and when passing through obstacles, and it is especially used for sunken pipe, pipe bridge (crossing over river) and jacking of pipe (crossing over the road).

(2) Ductile iron pipe(DIP)

Raw material of DIP is also pig iron with carbon constituent of 3.5-4.0%. Through spheroidization and annealing treatment after molding of pipe casting, the stable and even fine texture is obtained with fairly high specific elongation. According to standard of ISO2531, its specific elongation, tensile strength and water pressure test, etc., are all equivalent to steel pipe, and its anticorrosion is superior to that of steel pipe. The burying service life can be up to 50 years. DIP wall thickness is fairly thin and is only about 55% of that of the grey cast iron pipe. Inner wall is coated and sealed by cement. The roughness coefficient n is considered as 0.013(manning formula) for this design. At present, the diameter of DIP pipe produced in domestic is DN100�2600, it adopts the T form slide-in interface with water stop rubber ring, in general foundation condition the base shall not be treated, the mechanical and machining property is good, it can be welded, cut and bored.

(3) glass-reinforced plastic pipe(RPMP)

RPMP is a composite material pipe consisting of unsaturated polyester resin, glass fiber and quartz sand filler. The pipe wall is divided to external protection layer, reinforced layer, structure layer and liner layer according to different roles. The mechanical strength can be sorted according to design requirement, and its nominal rigidity is 2500�20000N/m2 and work pressure 0.4�2.5MPa. RPMP has small specific gravity (only 1700�2200kg/m3) since the weight is light it is relatively convenient for transportation and construction. The layer of inner wall contacting with water is polyester resin, it has fairly small roughness, and n value is 0.0095�0.01 for this design. Thus it can greatly lower the loss of water head and is not easy of scaling and corrosion, it has no impact to water quality, and has no need of internal and external insulation treatment. According to introduction, its service life shall be over 50 years. Joint of RPMP is usually socket connected or sleeve connected, with rubber ring or reversely grouted by rubber for water-stop, it is not easy of incurring water leakage and pipe explosion. Since the weight is light, it is more in favor of pipe laying and installation, in most foundation condition, it has no need to make base, and it is one of the ideal pipe materials for long distance water transportation.

RPMP consists of two processes of short fiber outer formwork centrifugal manufacturing and long fiber inner formwork winding manufacturing, the rigidity of the previous one is superior to the latter one, while the uneven settling resistance of the latter is superior to the previous one. Both of them can meet the general operation requirement of rigidity and withstanding of internal pressure, while the uneven settling of pipe foundation is usually one of the main causes of pipe accident, at present, the long fiber inner formwork winding manufacturing of RMPM has more utilization in domestic.

(4) Prestressed steel concrete pipe(PCP)

PCP is composed of longitudinal and loop prestressed steel wire (reinforcement) and coagulating earth, and its wall thickness is usually fairly large. Although its mechanical strength is inferior to SP, it can withstand fairly great internal pressure, at present, the common internal work pressure is below 1.0MPa, during ex-factory test, the external pressure (bending) can be over 1000MPa. PCP has best anticorrosion property without internal and external insulation, the service life is long and can be over 50 years. According to report, the PCP with good manufacturing shall seldom have the phenomenon of pipe explosion; hydraulic roughness of PCP is relatively small, at present the designed flow speed coefficient C is 130 (Hazen-Williams formula). In addition to corrosion resistance, the pipe is also not easy of incurring scaling, and has no impact to water quality. The joint usually adopts the socket connected type, with rubber ring water stop and convenient pipe laying, nevertheless weight of PCP is great and not in favor of transportation and hoisting. Under general foundation condition it may not be set by base. PCP pipe price is fairly cheap, when the pipe diameter is less than or equivalent to DN1000 and pipe work pressure less than 0.5MPa, it is an available pipe material.

(6) Prestressed concrete cylinder pipe (PCCP)

PCCP manufacturing is similar to PCP, and its difference is that, it adopts the integrated steel sleeve (fairly thin) to substitute the longitudinal prestressed reinforcement of PCP, thus it has better watertightness and is mostly of pipe of large diameter, such as DN1400-DN4000; usually the wall thickness is fairly large, as above mentioned, the wall thickness is respectively 100 and 270mm. the

large diameter PCCP adopts the double rubber ring for water stop, and this is greatly in favor of water pump test. Other physical and chemical characteristics and construction requirements of PCCP are similar to that of PCP. Price of PCCP pipe is fairly cheap, with simple laying at site. It is a pipe material with fairly good application for large diameter pressure water transportation pipe works. According to characteristics, anticorrosion and construction conditions, etc., of above pipes, safety and reliability of water supply, water transmission pipe diameter and laying condition for this project, the comparison on property of spiral-seam submerged-arc steel pipe (SP), ductile iron pipe(DIP), glass-reinforced plastic pipe(RPMP) and prestressed concrete cylinder pipe are shown in Table 7.3-5.

According to comparison and selection on properties and prices as above mentioned, the centrifugal ductile iron pipe has the highest integrated cost, and in turn is the spiral-seam submerged-arc steel pipe, and price of prestressed concrete cylinder pipe and glass reinforced plastics sand pipe is cheapest. Considering of the safety and reliability of water supply main pipe, ductile ion pipe is recommended for use.

Effluent water quality indicator of wastewater treatment plant is compared with indicator of reclaimed water, and effluent water after further treatment can meet the reuse standard of reclaimed water. 7.4.1.1 Comparison and selection on grade 2 biological treatment process According to the predicted influent water quality of wastewater treatment plant of this project in feasibility research report, and the discharge standard requirement of effluent water, in this project it adopts the grade2 biological treatment process with functions of eliminating organic pollutant and suspended solid, as well as nitrogen and phosphorus elimination. According to development of wastewater treatment technology in abroad and abroad, the various processes of A2O process, oxidation ditch process, and SBR process, etc., not only have the function of eliminating organic pollutant, but also have different nitrogen elimination effect. In the “urban wastewater treatment and pollution protection and prevention technical policy” printed and issued by construction ministry, national administration of environmental protection, and science and technology ministry, it is recommended that A2O process, oxidation ditch process, and SBR process shall be used for grade2 biological treatment process aiming at wastewater treatment plant with scale of wastewater quantity below 100000m³/d. According to various technical properties of processes, construction scale of this project, influent water characteristics, treatment requirement and local situation, in this appraisal it intends to select the SBR series CAST process and composite A/A/O process as the comparison and selection plan for wastewater grade 2 treatment of this project. (1) CAST process (Plan 1)

Periodic circle type activated sludge method (CAST process) is a transformation of intermittent activated sludge method. The biological degradation and sludge water separation processes are completed in one or multiple ponds with parallel run and variable reaction volume. Thus in this process it does not need to set the separate settling basin. In this system, activated sludge is continually repeated by “aeration—non-aeration”. In the stage of aeration it is mainly to complete the biological degeneration process, in the non-aeration stage, although it has part biological effect, it is mainly to complete the sludge water separation process. In circulated activated sludge

method process, the treatment process is completed as per sequence of “water filling— discharge” and “aeration—non-aeration”, it belongs to sequencing batch activated sludge method. Each operation circulation of this process is composed of influent water/aeration stage, settling stage, decantion stage and idle stage, each state constitutes a circulation and is continually repeated. When the circulation is started, the incoming of wastewater enables the water level in the pond start to rise from the lowest level. After some time’s aeration and mixing, the system stops the aeration so that the activated sludge in the reactor carries out flocculation settling, and activated sludge shall settle in the static environment. After completion of settling stage, the supernatant at the upper part of the pond is discharged outside the system by decanter, at the same time the level shall drop to initial depth. Then the system shall repeat the above processes. Main advantages of CAST process: y� The process is advanced and simple; the treatment building structure is small and equipment

number is small. Compared with A/A/O process it does not have secondary settling basin, the SBR process sludge adopting delay aeration is relatively aerobic and stable, and has no need to carry out treatment of anaerobic digestion, thus it has no need to set up building structures of anaerobic digestion system for sludge, etc., the operation management is convenient; it has very high phosphorus and nitrogen elimination effect, the process run is stable, and effluent water quality is good.

y� It does not have expansion of sludge, and growth of filamentous bacteria can be restricted. y� It has the double advantage of complete mixing type and plug flow aeration basin, and can

bear the fairly great impact load of water quantity and water quality change, and the treatment effect is stable.

y� The output of wastewater is small, the sludge can be gradually aerobic and stable, the number of wastewater treatment building structure is small, and the sludge only needs to be thickened and dehydrated.

Main disadvantage of CAST process: y� In the periodic circular activated sludge method, the reaction basin has fairly high

requirement of automatic control, and high requirement of reliability of equipment. y� The run effect in the low temperature is not stable. y� Idle rate of equipment is high.

(2) A/A/O process (Plan 2)

A/A/O process is anaerobe—oxygen deficient—aerobic activated sludge method. In front of aerobic area it is designed by oxygen deficient area and anaerobe area which shall respectively realize the denitrification nitrogen elimination and phosphorus elimination function. When the wastewater passes through three different function areas, under the effect of different microorganism bacteria group, the pollutants in the wastewater as organic substance, nitrogen and phosphorus, etc., are eliminated. When it has sufficient sludge age condition, BOD5 in the wastewater shall at first be degenerated in the aerobic basin, and at the same time the nitration is completed, the wastewater after nitration is lifted by reflux pump into the oxygen deficient basin to carry out denitrification and nitrogen elimination. Through the effect of backflow sludge for greatly absorbing phosphorus, the element of phosphorus is eliminate. The integral process includes following processes:

Assimilation process, some part of ammonia and nitrogen in the wastewater are assimilated into new cell substance, and eliminated via the form of residual sludge. The assimilation works is the process to eliminate the organic substance, and some part of nitrogen can be eliminated even there is no specific biological nitrogen elimination measure. Nitration process; The nitrifying bacteria shall oxidize the ammonia and nitrogen in the wastewater into nitrate nitrogen. Denitrification process, in the oxygen deficient environment and with participation of denitrify bacteria, the nitrate is deoxidized to nitrogen and emitted to atmosphere. The nitrogen effect of denitrification design is determined by the reflux ratio of activated sludge, usually 100%�150% can meet the requirement.

At the same time under the anaerobic condition, the phosphorous accumulating bacteria in the sludge is activated to release the phosphate in its body, so as to generate the energy to absorb the organic substance which can be quickly degenerated, and then it shall be converted to PHB for storage. After entering the aerobic area and when the oxygen is sufficient, the phosphorous accumulating bacteria consumes the PHB stored in its body to generate the energy, which shall be used for cell synthesis and phosphorus absorption, the sludge containing high concentration of phosphorus is generated, and shall be discharged outside the system together with the residual sludge, so as to reach the purpose of biological elimination of phosphorus. Since the treatment of wastewater is mainly of industrial waste water, it has bad biological and chemical treatment ability, sometimes it may have the deficiency of carbon and nitrogen source and has great impact load. During early stage the water quantity is small, water quality is low, according to local climate condition and on the basis of A/A/O, part filler and chemical auxiliaries are added to meet the high treatment effect, stable and low energy consumption status under different conditions.

(3) Comprehensive comparison For the convenience of comparison on two plans, it is compared and analyzed by two aspects as technology and economy, details refer to Table 7.4-1. Table 7.4-1 Integrated comparison on technology and economy

According to above analysis it is know that, two processes can both meet the effluent water quality requirement of wastewater treatment plant, nevertheless, A/A/O process has strong impact load resistance capacity, adapts to cold climate of project area, and has low technical requirement to operation personnel, furthermore, when compared with CAST process, A/A/O process has lower total investment of project, and lower annual operation cost and annual run cost, etc., thus in this project, it

is recommended that A/A/O process of plan 2 is utilized for each wastewater treatment works of processing park. 7.4.1.2 Comparison and selection on plans of reclaimed water treatment process In this project, the wastewater treatment works of processing park adopts the three section process (coagulating, settling, filtering) for reclaimed water treatment, each section of process can be selected, and comparison on each section of process is below: (1) Coagulating

Coagulating process contains mixing and reaction. y� Mixing Mixing is the precondition to obtain the good coagulating effect, and also the key to save the agent quantity. It usually adopted the mechanical fast mixing and hydraulic mixing, in recent years it mostly adopts the tubular static mixer which is a equipment with small land occupation and good mixing effect, and is widely utilized in domestic. The engineering practices prove that, this mixing unit has a lot of advantages, and thus the tubular static mixer is herein recommended. y� Reaction The reaction and flocculation process is the most critical link of water supply treatment, and effect of flocculation shall directly impact the settling effect, gas flotation effect and quality of effluent water. In this project it adopts the vertical mechanical reaction basin, bent plate reaction basin, small mesh grid reaction basin to carry out comparison on plans, details refer to 7.4-2.

According to above comparison it is know that, the advantage of vertical mechanical reaction basin is not apparent in this project, in addition to high total investment and great power consumption, it is added by a lot of maintenance and management work, and its land occupancy is great, thus it is not recommended. The mesh grid reaction basin has the advantages of new type, high efficiency, potential, small land occupancy, low investment and low reagent consumption, furthermore, this system has been successfully run in the north regions of Moudanjiang City, Daqing City, and Dalian City, etc., thus in this project, the small mesh grid reaction basin is recommended.

(2) Settling

The settling means the process to eliminate the solid particle in the suspension liquid via the precipitating action of gravity. In the water cleaning process, in order to reach the purpose it usually adopts the treatment building structures as horizontal flow settling basin, slope tube settling basin, slope plate settling basin, and comparison on plans of three basin types are shown in Table 7.4-3.

Table 7.4-3 Comparison on plans of settling basin.

1. The treatment effect is good and the land occupancy is small. 2. It is placed in indoor conditions, and the investment is lower than horizontal flow settling basin.

1. It has very good treatment effect, settling time is short, land occupancy is small, and hydraulic condition is good. 2. The water id distributed at the short side, and the water is collected at tail end by same process and same resistance, and the collection tank in the basin can be cancelled. 3. The settling basin has matured experiences of design, installation, and run.

Technical comparison

Main disadvantages

1. It has great land occupancy, and great basin body as well as high investment cost. 2. The open basin shall be frozen during winter, when it is placed in indoor condition, the investment cost shall be greatly increased.

1. Its adaptability to raw water is inferior to that of horizontal flow settling basin. 2. It has high requirement to reaction effect, and evenness of water distribution. 3. The plastic slope pipe has the problem of replacement for aging.

1. The application time of this technology is relatively short.

According to above comparison it can be seen that, slope plate settling basin has more advantages of economy and other aspects when compared with horizontal flow settling basin and slope tube settling basin. The slope plate settling basin is the new type and high efficiency one developed in 1990s, and its characteristics are: effluent water quality is good and stable, it has strong adaptability to change of raw water temperature and quality, hydraulic condition is good, settling time is short, land occupancy is small, potential of output water is great, and slope plate settling basin has been widely utilized in the north regions as Moudanjiang City, Daqing City and Dalian City with very good effect of operation, thus slope plate settling basin is recommended for this project.

(3) Filtering

Filtering is the most critical work sequence of water supply treatment, at present it usually adopts the fast filtering basin to eliminate the residual flocculants and foreign substances after coagulating and settling of raw water. According to different structure forms of the filtering basin, at present it usually adopts the general fast filtering basin, double valve filtering basin, siphon filtering basin, movable hood backwash filter basin, and V type filtering basin, etc. In this project it intends to select the general fast filtering basin and V type filtering basin. Comparison on plans is shown in Table 7.4-4.

Table 7.4-4 Comparison on plans of filtering basins

Item

Main advantages

1. The filtering speed is high, basin body is small and land occupancy is small.

2. The waste water discharge quantity is low, energy consumption is low and investment cost is low.

3. The effluent water gate is controlled by level of filtering basin liquid, so as to control the filtering speed.

2. It adopts the sand filtering material, the material can be easily obtained and the price is cheap.

3. It adopts the large resistance water distribution system, the single basin area can be fairly great, and basin depth is appropriate.

4. It adopts the decelerated filtering and water quality is fairly good.

Main disadvantages

1. It is added by water supply equipment, and this increases the infrastructure construction investment and increases the work volume of maintenance.

2. The basin structure is complicated, especially it has high accuracy requirement to water distribution and gas distribution system, and this adds the difficulty of construction.

3. The area if single basin is averagely greater than unit basin area of general filtering basin, but it is not comprehensively utilized, because the discharge tank in the middle position occupies a part of area, and in fact, the actual filtering area is smaller than single basin area.

4. The back flush operation is complicated especially in case of manual operation.

1. It has a lot of valves with expensive price and valve can be easily damaged.

2. It must be set by complete set of flushing equipments.

According to above comparison it is know that, the general fast filtering basin has more stable and reliable operation than V filtering basin, its process is simple with low technical requirement to operation personnel, and can meet the actual situation of local area of this project located. Furthermore, the general fast filtering basin has been widely utilized in the deep processing works of wastewater of China. Thus in this project, the general fast filtering basin is recommended.

7.4.2 Comparison and selection on sludge treatment processes During wastewater treatment process it shall generate a large number of sludge containing various hazard and toxic substances, thus it shall be timely treated and disposed. It usually has the following processes of sludge treatment: anaerobic digestion, aerobic digestion and direct thickening and dewatering. When anaerobic digestion is adopted, it can recover the energy, but its capital cost is fairly high, with operation and maintenance problem, great land occupancy, and safety hidden trouble, furthermore, it shall decrease the effect of biological elimination of phosphorus and increases the quantity of reagent addition. According to statement of “503 Standard of Wastewater and Sludge Treatment ” of EPA of U.S.A., the treatment effect of aerobic digestion for sludge with staying time of 60 days in 15�, and 40 days in 20� is only equivalent to the anaerobic digestion treatment effect of 35� and 15 days of moderate temperature. Apparently, it is not economic to realize the stable aerobic digestion in the large and middle urban wastewater treatment plant, the data shows that, sludge aerobic stabilization technology is only utilized for the wastewater treatment plant below the capacity of 20000 m³/d. Since the sludge age of wastewater treatment is fairly long, and has aerobic stabilization for some

extent, the generated sludge quantity is fairly small. The biological nitrogen and phosphorus elimination process has been utilized for many completed wastewater treatment plants in domestic and abroad, the generated sludge is directly thickened and dehydrated, the operation is stable, and this proves that, the direct thickening and dewatering are feasible. As above mentioned, in this project, it is recommended to adopt the direct thickening and dewatering for sludge treatment. 7.5 Comparison, selection and analysis on alternatives of treatment works of Wuliansu Lake 7.5.1 Comparison, selection and analysis on constructed wetland 7.5.1.1 Regional location of constructed wetland Constructed wetland is located in the west part and north part of Wuliangsuhai lake area, which shall respectively treat the lake influent water of general drainage canal , drainage canal 8 and drainage canal 9, the regional location is shown in Fig. 7.5-1. No.2, No.3, and No.4 areas are respectively located in the north west area of Wuliangsuhai and mainly for treatment of drainage water of general drainage canal. No.5, No.6 and No.7 areas are located between drainage canal 8 and drainage canal 9, and in the south side of drainage canal 9, which are used for treating drainage water of drainage canal 8 and drainage canal 9.

According to characteristics of wetland of Wuliangsuhai, constructed wetland system is divided to three subsystems: Stabilization pond subsystem and surface flow reed area subsystem. Finally two wetlands are regarded as integrity for simulation (Fig. 7.5-2).

Fig. 7.5-2 Input interface of model parameter 7.5.1.3 Main design parameter

(1) Design of water quantity and water quality

Waste water treated by constructed wetland is the drainage of drainage canal 8 and drainage canal 9, according to water quantity statistics for years (1998-2008), total drainage water into the lake is 460million m3, considering of impact to water quantity after completion of waste water plant and reuse water in the upper reaches, it is predicted that total drainage quantity into the lake is 424million m3, after completion of waste water treatment plant and reuse water plant, it shall not be discharged to general drainage canal, thus it does not have impact to water quality of total drainage. Annual mean discharge water quantity is 42million m3 for Drainage canal 8 and 22million m3 for Drainage canal 9, totally 64million m3, after completion of waste water plant and reuse water plant at upper reaches, it shall not take water from or discharge water into Drainage canal 8 and Drainage canal 9, thus it shall not impact water quality and water quantity of No.8 and Drainage canal 9. The Design flow of delay wetland system adopts the annual mean daily flow, wherein, pump and water gate, etc., in the wetland system are computed as per maximum monthly flow. Water quality of general drainage canal shall adopt the mean value from Dec., to Apr. of next year, nevertheless, considering of influent water quality and quantity of Wuliansu Lake, specific local climate condition and specific condition of wetland, the design water quality shall be subject to maximum concentration of non-icebound season from May to Nov., as shown in Table 7.5-1. Table 7.5-1 Designed water quality of influent water of constructed wetland

Indicator CODCr BOD5 NH3-N TN TP

Value (mg/L) 60 - 2.4 13.5 1.7

Note: BOD5 lacks measured data. (2) Elimination rate In the wetland, elimination of biochemical oxygen demand can be described by following order 1 reaction dynamics, with apparent correlation (P<0.1) .

)exp(]/[ tKCC TOe −=

Wherein, Ce ——Influent water BOD5�mg/L; Co ——Exfluent water BOD5�mg/L; KT ——First order reaction constant, d-1; t ——Hydraulic power staying time, d.

(2) Hydraulic load and staying time According to the elimination rate predicted, the above formula can be used to compute the hydraulic power staying time required for wetland. In the delay wetland, since great growth of reed occupies a part of space, and the staying time is the function of wetland porosity, during calculation, porosity n shall be taken into account. (3) Area and water depth of delay wetland system In the wetland system, water depth of stabilization pond is about 2.0m, water depth of wetland is controlled by about 1.0m. (4) Water flow status In the wetland system, length to width ratio of hydraulic unit has important impact to hydraulic characteristic. Since area of reed field is very great with irregular form, during design of flow channel, it shall to the greatest extent adopt the diversion dam to make the water flow status gradually approach to plug-flow mode, hydraulic characteristic is improved to increase the elimination rate. (5) Accumulation depth and clearing period of sludge of pond bottom Accumulated depth of sludge is 0.3m, it shall be cleared for interval of every 5-10 years. 7.5.1.4 Plan 1 In plan 1 it adopts 2#, 3#, 4#, 5#, 6# and 7# reed field, wetland of general drainage canal is 2#, 3# and 4# reed field. Wetland of Drainage canal 8 is 5# and 6# reed field, wetland of Drainage canal 9 is 7# reed field. Total land occupancy area is 116914 mou. (1) General drainage canal wetland Wetland of general drainage canal adopts the 2#, 3# and 3# reed field as shown in Fig. 7.5-3, and its total area is 90514 mou. Returned water is lifted by Honggebu pump station and then enters reed field of 4# military area farm via the diversion sluice, through the diversion dam set in the reed field, it is diverted and enter 2# reed field and then 3# reed field via the water channel with width of 1000m in the inner side of lake dam, wherein, the incoming water of Yihewu channel has small quantity and seasonality as well as also directly enter wetland system, finally, through three outlets at the connection between reed field and lake, it enters grid water channel of big lake area via the rubber dam. At present, water level of reed field is lower than level of lake area, effluent water of wetland enters lake area (mostly relies on self flow), therefore it shall run by raising the water level, on the basis of existing water level it shall be raised by 50-70cm. In the branch current from general drainage canal to 4# reed field it is built up by a water interception gate (rubber dam) to control the water current into 4# reed field. When the incoming water of upper reaches during flood season is fairly great, or when water quality is fairly good, the water quantity can be directly regulated for entering the lake. Effluent water

of wetland mainly relies on self flow, facilities at location of three outlets comprehensively takes into account the requirement for improving hydraulic power condition of lake area, and water quantity distributed is respectively 20%, 20% and 60%. If the dam in the circumference of reed field needs to be reinforced and heightened, it may be done on the previous foundation. The border-in position between reed field and lake is the lake dyke, width of previous lake dyke is mostly about 2.0-2.5m and height 1019.0-1019.6 m, and there is no lake dyke at individual section. Elevation of normal lake water level is 1018.5m, maximum elevation of lake level is 1019.3m, thus designed elevation of lake dyke is determined as 1020.0m; Its width shall take into account the stability and transport requirement in the water, dyke top width is 5.0m, slope 1:2.0, and height is 2.5m. Rising water level may incur rise of groundwater level of farm in the circumference and impact normal farming work, at the outside of reed field of wetland it shall adopt vertical plastic laying technology for reverse osmosis treatment. Vertical plastic laying burying depth is about 8m, along a circle of periphery of constructed wetland it shall be set by vertical plastic laying facilities for reverse osmosis purpose, and its total length is 40km. At the water outlet is set by one discharge station with flow of 30 m3/s playing the role of drainage of wetland and lowering wetland level. Since run level of wetland is raised, during icing in winter, the ice layer cannot reach the bottom of wetland, and there is also a part of flow cross-section remained, thus freezing period of wetland of general drainage canal can continue with its run. Nevertheless, oxygen cannot reach water system beneath the ice due to blockage of ice layer, in order to improve elimination rate in winter, in the stabilized pond it is set by aerating apparatus. (2) Drainage canal 8 wetland Wetland of Drainage canal 8 adopts No.5 wetland and No.6 wetland with area of 15300mou. Incoming water enters 5# reed field to raise the water level for its run. Through culvert pipe it enters 6# reed field via Changji channel. Since water level is raised for run, in the periphery of reed field it is done by reverse osmosis treatment via the method of vertical plastic burying, and its length is 4.7km. Drainage canal 8 during winter basically does not have incoming water and has no operation in winter, and aerating pond shall not be set up. Prior to coming of freezing period, water of reed field can be discharged to rear pond of pump station and then into the lake, so as to lower the level of wetland and to the greatest extent avoid the reduction of output of reed. (3) Drainage canal 9 wetland Wetland of Drainage canal 9 adopts part area in No.7 reed field with area of 11100 mou. Incoming water enters 7# reed field to raise the water level for its run, it in turns passes through reed field and then enters the lake via south west corner of reed field. It is set by vertical laying of plastics of 8.5km. After raising the water level it shall impact the output of reed, prior to coming of freezing period the water in the reed field shall be discharged to rear pond of pump station of Drainage canal 9 and then into the lake, so as to reduce water level in the reed field and avoid reduction of output of reed. Drainage canal 9 basically has no incoming water in winter, and is not run in winter, and aerated pond is not setup.

(2) Drainage canal 8 wetland Wetland of Drainage canal 8 only adopts 5# reed field with area of 8569mou. Incoming water enters reed field to raise the water level for run, it in turn passes through wetland along direction of diversion dam, and finally enters the lake area from the diversion sluice (as shown in location of Fig.). Since it is run with rising of water level, in the periphery of reed field it shall be done by reverse osmosis treatment via the vertical plastic burying method. After raising the water level it shall impact the output of reed, prior to coming of freezing period the water in the reed field shall be discharged to front pond of pump station of Drainage canal 8 and then enter lake via the pump station, so as to reduce water level in the reed field and maintain output of reed. Drainage canal 8 basically has no incoming water in winter, and is not run in winter, and wind energy aerated pond is not setup.

(1) General drainage canal wetland Wetland of general drainage canal adopts the 1#, 2# and 3# reed field as shown in Fig. 7.5-5, (4# shall not be utilized), and its total area is 105791 mou. Returned water is lifted by Honggebu pump station and then enters 2# reed field along water channel between 4# reed field and lake via the diversion sluice, through the diversion dam set in the reed field, it is diverted and enter 3# reed field, finally, through three diversion sluices between 3# reed field and lake it enters 1# area of the lake, and then enters grid water channel of lake via the water outlet. Since wetland is in the lake with fairly great difficulty of construction, it shall not be made by diversion dam works.

(1) Comparison on land occupancy area Land occupancy areas of three plans are shown in table 7.5-2. Land occupancy area of Plan 1 is 116914 mou, wherein, in small lake area it is 102580 mou, in big lake area it is 14325 mou; Land occupancy area of Plan 2 is 101839 mou, wherein, in small lake area it is 95858 mou, in big lake area it is 14325 mou; Land occupancy area of Plan 3 is 125460 mou, in small lake area it is 73742 mou, in big lake area it is 51718 mou. Plan 2 has smallest area of land occupancy, in the big lake area the land occupancy is same as that of Plan 1, in the small lake area the area is smaller than that of Plan1 and more than that in Plan3. Total land occupancy area of Plan 1 is equivalent to plan2, nevertheless, in the small lake area, the area is larger than that in plan2 and plan3. In the big lake area of plan 3, the land occupancy area is far above other two plans. In three plans, it all adopts 2# reed field of the lake. The result of lake area model simulation shows that, utilization of 2# reed field is very critical to improve hydraulic power condition of whole lake, due to this consideration, in all plans, 2# reed field is utilized. 2# reed field in the lake has minor impact to lake since it is separated from the main lake area. Nevertheless, 1# lake area has great impact to the lake. It greatly reduces the area of Wuliangsuhai Lake area, and wetland project scope is greatly adjacent to core area and buffer area of the lake, and this is not in favor of protection of core area. According to viewpoint of land occupancy, plan 2 is optimal. Table 7.5-2 Land occupancy area of three plans

Scope Plan 1( mou) Plan 2( mou) Plan 3( mou)

Small lake area 102589 95858 73742

Big lake area 14325 14325 51718

Total up 116914 110183 125460

Due to raised-level run of wetland of general drainage canal, in the periphery of wetland it needs to be done by reverse osmosis treatment, and it may adopt two methods. One method is to excavate the seepage interception ditch, and the other method is to adopt vertical burying of plastics for reverse osmosis. Depth of seepage interception ditch is about 3m and width 10m. Depth of vertical burying plastics is about 5m. After computation, investment cost for applying seepage interception ditch is about 400000RMB, while investment cost of vertical burying plastics is about 200000RMB. Furthermore, seepage interception ditch has great land occupancy area and reduces farm land, as well as needs economic compensation. Seepage interception ditch has fairly serious soil erosion and needs to be periodically dredged. Relatively speaking, construction of vertical burying of plastics is simple with small land occupancy and without subsequent issue. Thus it adopts the plastics vertical burying method to prevent from seepage. (2) Comparison on cleaning effect of wetland Wetland elimination rate of three plans is respectively shown in Table 7.5-3~Table 7.5-5. Data of the table is mean value. Wherein, Drainage canal 8 and Drainage canal 9 do not have operation during freezing period. Table 7.5-3 Plan 1: Elimination rate of pollutant of wetland

According to above table, design of plan 1 and plan 2 for wetland of general drainage canal are consistent with same elimination effect. Elimination effect of plan 3 is slightly lower, because 1# wetland is in the lake and has not setup of diversion dam, thus water current can easily incur short current and section current and cannot comprehensively play the effect of space of wetland. As to Drainage canal 8, since it has great land occupancy, elimination effect of plan 1 is best, and effect of plan 2 and plan 3 is of the same. Design of three plans for Drainage canal 9 is consistent with same elimination effect. (3) Current situation of reed field and feasibility demonstration of utilization Constructed wetland project of biological transitional area of Wuliangsuhai Lake must integrate and utilize the existing reed field in the north and west part of lake area. Hetao Water Supply Group visited and surveyed 47 villager groups of 10 administrative villages of three farms (Xishanzui Farm, Xin’an farm, and military area farm), and two towns (Xin’an Town, and Dashetai Town), the result showed that, reed field of north part and north west part of lake area is difficult for utilization. The utilization mode for reed field is most feasible, while the renting mode has the problems of great cost and great

difficulty. In plan 2 and plan 3, the reed field area of wetland of drainage canal 8 is reduce, and it can also ensure the elimination rate of pollutant, and thus can be regarded as preferred plan. (4) Comparison on work volume and project difficulty In Plan 1, area of reed field is biggest with biggest work volume. Drainage canal 8 adopts 5# and 6# reed fields, between them is Changji Channel, when water flows into 6# reed field from 5# reed field it needs to be made by culvert pipe for passing through Changji Channel, the work volume is increased, and construction difficulty is also increased. In Plan 2, the area of reed field is smallest. Drainage canal 8 only adopts 5# reed field, Drainage canal 9 adopts 7# reed field, and at present in the rear pond of pump station of No.8 and Drainage canal 9, it is set by drainage ditch for these two wetlands. It can be utilized by making slight modification, and water current shall not cross over Changji Channel. Since the area is small, the work volume of pond and diversion dam in the wetland is also decreased. Area of plan 3 is slightly larger than that of plan 1, nevertheless it adopts the reed area of north side of big lake area, and the difficulty for excavation, dam building and construction of diversion sluice in the lake area is far above that on the land. The main issue is that, it occupies area of lake and reduces area of Wuliangsuhai Lake area, periphery of wetland is adjacent to core area and buffer area, and this is not in favor of environmental protection of core area and buffer area. Work volume of three plans is shown in table below, according to Table 7.5-6, work volume of plan 2 is smallest. Table 7.5-6 Comparison on main work volumes of three plans

�7�Optimum Option The ananlysis of wetland components for Main Drain Canal , Drain #8 and #9 is undertaken in terms of pollution reduction, water quality improvement, and investment cost on the basis of Option 2. The result shows: (i) the pollution load reduction through Drain #8 and #9 equals just 3-4% of the total pollution load reduction, (ii) the cost/benefit ratio for Drain #8 and #9 is 5 times worse than for the Main Drain, (iii) the direct investment cost for total wetlands could be reduced by 21% if wetlands of Drain #8 and #9 are eliminated, a few impact, only 1-3% on water quality of Wuliangsu Lake. The final result is the Main Drain Canal welalnd (No. 2, 3, and 4 reed fields) with a total area of 90514 mu.

According to simulation result of flow field simulation of lake area of three plans and Table 7.5-11, the following conclusions can be made:

y� Compared with zero plan of flow field with current situation, three diversion plans can apparently improve the flow status of reservoir area, and the dead water area of large area of Dongdatan water area, etc., is basically eliminated, under the non wind condition, the dead water area can be reduced by about 30-40 km2;

y� It only dredges and extends the drainage canal, the flow speed of main flow area of south part of lake area is slightly increased, it has minor impact to flow status of north part and west part of lake area, and the improvement effect of integrity of lake area is limited.

y� In the reed area of the lake, the water channel is dredged and extended, the drainage canal and branch canal are executed, dead water area of lake area is reduced by over 10 km2, main flow field of lake area is smoother, and integral flow status of lake is greatly improved.

y� Dead water area of plan 1 is basically equivalent to that of plan 2, compared with plan 1, dead water area of plan 2 is reduced by 1.40 km2 without apparent difference. The dead water area of plan 3 is minimum, because the 1# area of lake area is occupied by wetland and lake area is accordingly reduced. According to viewpoint of optimization of flow field of lake area, plan 2 is optimal, and is related to water outlet plan of wetland.

8. Analysis on Environmental and Economic Loss and Profit The integrated water environmental improvement works of Bayannaoer Municipality with WB loan is important component of the infrastructure of the city, which has far-reaching significance in improving the water environment of Bayannaoer Municipality, dispatching water resources, maintaining the normal operation of urban functions and promoting the harmonious development of the society, economy and environment. 8.1 Project Development Target and Impact Analysis The development target and overall impact of the project are included in Table 8.1-1. Table 8.1-1 Development Target and Overall Impact of the Project Development target of the project Predicted project impact

Dispatch water resources, improve utilization rate of water resources Cut off pollutant, improve the quality of water environment Improve the water circulation of lake, strengthen the self-purifying capability of lake, and retard the process of paludification

Reclaimed water supply works, wastewater treatment and recycling works of processing park and sea area treatment works of Wuliangsuhai Lake will cut off the pollutants discharged into the lake, alleviate the deterioration trend of water environment of Wuliangsuhai Lake, and provide necessary urban environment and infrastructure for the development of Bayannaoer Municipality and finally support the sustained development of economy from the environment

Improve water environment and quality of Wuliangsuhai Lake, and protect the safety of ecological water environment of the Yellow River

8.2 Economic Benefits (1) Economic Benefits of Reclaimed Water Supply Works The unit water sale price of different reclaimed water supply works of the project is calculated with VAT, urban maintenance & construction tax, additive education fee and others expenses plus proper profits on the basis of total costs. The reclaimed water supply works can realize annual average operating incomes of RMB79.7525 million & total annual average profits of RMB19.3925 million after completed. Financial analysis reveals that the net profit rate of all the investments of various reclaimed water supply works is 5.16% on average, the period of the returns on investment is 12.9-13.32 years, various financial indicators are predicted as good and the balance point of profit and loss is safe. It proves that the project still has some economic benefits from the angle of financial evaluation although the project is urban infrastructure. (2) Economic Benefits of Wastewater Treatment and Recycling Works of Processing Park According to Interim Regulations on the Charges for Drainage Facilities of the Ministry of Construction, with reference to the experiences of relevant cities, in combination with the practical situation of this works, the collection of the charges for disposing pollutants enables this works to realize some economic benefits. The wastewater treatment and recycling works of processing park of the project can realize annual average operating incomes of RMB61.612 million, and total annual average profits of RMB18.032 after completed. The financial analysis shows that the net profit ratio of all investments of wastewater treatment and recycling works of processing park is 5.20% on average, and the period of investment recovery is 14.21 years. Various financial indicators are predicted as good and the balance point of profit and loss is safe. It proves that the project still has some economic benefits from the angle of financial evaluation although the project is urban infrastructure. Indirect economic benefits of the investment of the wastewater treatment and recycling works of processing park are also obvious, and mainly realized via less economic loss of the society produced by emission reduction of pollutants, with main forms as follows: y� Industrial Enterprises

Additional investments and operation managing expenses of the industrial enterprises for scattered in-depth wastewater treatment can be reduced and the environmental protection burden of enterprises can be alleviated; and project construction includes domestic wastewater disposal

system in service area and as a result, the project will exert the large-scale and low-cost advantages of the whole works, reduce wastewater disposal construction cost of individual enterprise and promote the construction and development of the enterprise in processing park after completed.

y� Agriculture After the project is implemented, the waste water of wastewater disposal plant is used in industrial enterprises of processing park after in-depth treatment. As a result, the project can save water resources and adjust the conflict between industrial water consumption and agricultural water consumption.

y� Personal Health The project can improve the water quality of the general trunk channel and Wuliangsuhai Lake, boost up local sanitation conditions, reduce the morbidity of diseases, cut off medical care and service expenses, and promote the labor productivity after completed.

The wastewater treatment and recycling works of processing park, important component of urban infrastructure is one public welfare project protecting the environment and benefiting the people. Direct and indirect economic benefits of the project are very obvious. It can improve water quality of trunk channels and Wuliangsuhai Lake, the water environment status of the project area and the investment environment of Bayannaoer Municipality, and promote the land value increment of potential area. Therefore, the implementation of the project has certain benefits for national economy, and plays an important role in improving water environment quality of Bayannaoer Municipality and promoting harmonious development of society, economy and environment. (3) Economic Benefits of Sea Area Works of Wuliangsuhai Lake The economic benefit of the sea area works of Wuliangsuhai Lake is realized mainly through the incomes of the reed industry, fishery and tourism of artificial wetland works of Wuliangsuhai Lake: In virtue of reed land of artificial wetland, annual reed output can increase from 120,000t to 150,000t, and as per RMB100 unit price, additional RMB3.0 million incomes can be created; the fish culture in stabilization pond of artificial wetland can add breeding area of 2000mu and create an additional output of 1000t, and as per RMB4000/t unit price, RMB6.0-12.0 million can be created; and the improvement of ecological environment of the wetland of Wuliangsuhai Lake could provide better conditions for ecologic tourism. It’s predicted that the area can accommodate 100,000 tourists/time, and realize annual operating income of RMB35 million and annual average after-tax profits of about RMB14 million. Therefore, sea area treatment works of Wuliangsuhai Lake has good economic benefits. The construction of artificial wetland works can obviously improve water quality and eutrophication of the whole Wuliangsuhai Lake. Wastewater flows into the lake after wetland treatment and is able to improve water quality by one grade. Inlet water quality of wetland in summer is Cat-IV or better Cat-IV by and large. In frozen season, the pollutant in water is largely cut off. Sea area grid works can obviously improve the self-purifying capability and environment capacity of Wuliangsuhai Lake. Artificial wetland and sea area grid works can greatly reduce the probability of the pollution accident of Wuliangsuhai Lake and the Yellow River, avoid the direct and indirect loss of the accident, and cut off pollution treatment expenses of the accident.

8.3 Social Benefits The project as urban infrastructure construction project will improve urban infrastructure level, better the quality of regional water environment and play a key role in beautifying the city after completed. Moreover, the construction of the project will improve investment environment, facilitate foreign investment, and play active role in promoting sustainable development of the economy. The reclaimed water supply works can adjust water resources, alleviate the water consumption conflict between industry and agriculture, inconsistency of the demand and inadequate water supply of processing park, improve the investment environment of the processing park, and ensure the sustainable development of processing park as per the overall planning after completed. The wastewater treatment and recycling works will improve the surface water quality of the trunk channels and Wuliangsuhai Lake, avoid or reduce the loss of industry & agriculture caused by

wastewater and play important role in preventing various infectious and common diseases and bettering people’s health after completed. In the implementation of the integrated sea area improvement works of Wuliangsuhai Lake, the construction of artificial wetland will cut off surface source pollution of agriculture, improve water environment quality, and promote the growth of fish culture and reed output, and increase the work opportunities and incomes of residents; the control demonstration and popularization project of surface pollution source can promote the agricultural development of the valley of Wuliangsuhai Lake, improve agricultural incomes and maintain local living habit; grid waterway works will improve water circulation of the lake, and strengthen self-purifying capability of lake, retard paludification, and protect and restore unique biologic value of Wuliangsuhai Lake. Therefore, the implementation of the works can not only improve the water environment quality of Wuliangsuhai Lake, protect the safety of water biologic environment of the Yellow River, but also boost up the living level of local people, and help the people live in peace and contentment, and maintain the stability of the society. 8.4 Environmental Benefits The project, key public-welfare infrastructure for maintaining sustainable development of economy, protecting water resources and preventing the water pollution, is the construction project improving ecologic environment, ensuring the health of people and benefiting society. The environmental benefits of the project are as follows: 8.4.1 Improving Hydraulic Conditions of Sea Area At present, reed grows widespread in Wuliangsuhai Lake. Especially in the northwest of the sea area, reed nearly covers the lake besides the open water surface in Xidatan. With the prevalence of reeds and increase of water flow resistance, large-size backwater area shapes in reed growing part. Simulated results prove that the water flow is weak in lake under the impact of incoming and outcoming flow. Besides 3mm/s-8 mm/s flowing speed in main flow area, a flowing speed of 1mm/s-1cm/s exists in most water areas. The backwater area in existence causes unsmooth water flow and bad water exchange conditions, and tends to create anaerobic and anoxic environments. As result, the organic substance is fermented, and lake water smells unfavorably. With the implementation of grid waterway works of Wuliangsuhai Lake, water flow condition of sea area is obviously improved. The main flow area of lake is smoother. Especially, the large-size backwater area in Dongdatan and other parts is eliminated by and large. In no-wind conditions, the size of backwater area can decline by 30-40 km2. The whole hydraulic conditions of the lake are largely improved. 8.4.2 Reduction of Pollutants The reclaimed water supply works is able to reasonably dispatch water resources, improve utilization rate of water resources, reduce the exploitation of underground water resources by 51.024 million m3, protect underground water resources, alleviate the continuous decline of underground water level, and prevent the expansion of funnel area, reduce the emission of CODcr, BOD and ammonia nitrogen by 2847.0t/a, BOD 1335.9 t/a & 491.29t/a and TP 71.54t/a�respectively, and improve the regional ecologic environment. Sewage treatment and recycling works of processing park can improve the degree of industrial wastewater treatment as well as sewage recycling rate, better the present water quality of the trunk channels and Wuliangsu Lake, and reduce or avoid the economic loss caused by sewage emission to industrial and agricultural production. The swage treatment and recycling works of the project can save water resources by about 22.63 million m3/a if 80,000m3/d sewage treatment capability and 64,000t/d reclaimed water calculated, reduce pollutant emission of the valley i.e. CODcr by 14600.0t/a, BODcr by 8760.0t/a, ammonia nitrogen by 730.0t/a�TP 87.6 t/a, and play significant role in cutting off the total pollutant emission of the region after completed. After completed, ecologic-transitional-belt artificial wetland of Wuliangsu Lake can reduce surface source pollutant of agriculture, cut off CODCr, TN and TP by 7405.38 t/a�1327.86 t/a �192.14 t/a respectively through its treatment, and largely improve the quality of water flowing into the lake. In

summer, outlet water quality of wetland is Cat-IV or better than Cat-IV by and large. In frozen season, the pollutant in water can be reduced as well. It plays significant role in gradually rducing eutrophication status of the lake area, boosting water quality of lake area, and bettering water environment. 8.4.3 Improving Water Quality of Sea Area of Wuliangsuhai Lake The grid waterway system will improve water quality of sea area by itself after implemented. Because the hydraulic conditions are improved and water exchange is strengthened after the implementation of trunk and branch canal waterway system, the isotropic function of quality of water system is reinforced and overall water quality of lake area is improved. In non-frozen period, Cat-V water area with organic substance declines by 17 km2, and water area better than Cat-IV increases by 8%, and the Cat-IV water area increase by about 3%; the inferior Cat-V water area with TN decreases by 14.2 km2, and Cat-IV water area increases by about 6.1 km2; better Cat-IV water area with TP increases by 8.2 km2, and Cat-IV water area decreases by about 12 km2. The most important function of sea-area grid waterway for water quality improvement is the optimal configuration of water outlet position and quantity of artificial wetland. After grid waterway reasonably configures wetland outlet position and quantity, COD concentration of the lake is largely improved. In the frozen period, inferior Cat-V water area decreases by about 123 km2. In non-frozen period, COD concentration largely declines, and inferior Cat-V water area is nearly eliminated in the whole lake, Cat-V water area is 100-127 km2, Cat-IV water area is 86-98 km2, Cat-III water area reaches 26-41 km2. In frozen period of the lake, inferior Cat-V water area with TN decreases by about 25-40 km2, Cat-IV water area increases by 28-50 km2; and in non-frozen period, TN improvement effect is obvious. Inferior Cat-V water area decreases by 101-120 km2. In frozen period of the lake, better Cat-III water area with TP increases by about 18-55 km2; and in non-frozen period, TP improvement effect is obvious as well. In the whole lake, lower-than-Cat-V water area is eliminated by and large. Inferior Cat-III water area increases by 90-110 km2. 9. Public Consultation and Information Disclosure 9.1 Public Consultation 9.1.1 Goal of Public Consultation y� To investigate and visit general public affected by the project environment; strengthen the

bilateral conmmunication between construction project and the public; understand support level and suggestions of the public to the construction project, such as environmental protection measures; potect residents affected by the construction project from harmless impacts; and reduce environment disputes caused by the construction project after project operating.

y� To introduce related situation of the project to the public; collect feedback, in order to find existing problems; provide related remedial measures and suggestions; draw the whole society’s attention to environment protection industry; improve environment rationality and society acceptability of the project; and provide decision-making suggestions and action basis for environment protection departments and construction unit.

Social Impact and Migrant Resettlement 10.1 Social Impact Analysis 10.1.1 Project Impact and Service Scope Various sub-projects of the project totally involve five banners (counties) of Bayannaoer Municipality i.e. Wulatehouqi County, Wulateqianqi County, Hangjinhou Banner, Wuyuan County and Wulatezhongqi County, four administrative villages of four towns (townships), one state-owned farmland and one state-owned range land. The construction of the project will exercise negative impact upon local area such as land requisition and relocation unavoidably. According to the design fruits of feasibility study report of various projects, 758.00mu land of different types is to be purchased for the project, including 190.50mu cultivated land, 165.00mu construction land and 397.50mu unused land. 271.73mu land of different types is to be temporarily purchased, including 68.33mu cultivated land and 203.40mu unused land. Moreover, the process of the engineering construction will cause some negative impact on local environment. In project implementation, the project employer unit and relevant design units will define a reasonable migrant resettlement proposal and environmental protection plan according to national and local laws and statutes for reducing negative impact of project construction upon the local. However, the construction of the project has a great positive impact on the local social and economic development and environments. Particularly, local water environments will be obviously improved. The implementation of project will effectively promote the development and utilization of coal, iron and copper and other mineral resources in Mongolia adjacent to the project area, boost up regional international economic cooperation, purify water system of Wuliangsuhai Lake, an important wetland in Northwest China and protect the Yellow River against pollution. Therefore, it’s integrated treatment project with outstanding environmental effect, social and economic benefits. The visit survey on the site reveals that the residents in the area under project impact highly support the construction of the project. Main service scope of various sub-projects is the enterprises in industrial park of the banner (county) that the project involves. The commencement of the project will reduce the water consumption, improve the utilization efficiency of water resources and better water environment. 10.1.2 Project Impact Analysis 10.1.2.1 Analysis on Status Quo of Project Impact Area According to Plan Report of Migrant Resettlement Action of the project, four villages in the scope of project impact are investigated.

The above table can reflect the outlays of the households under project impact in 2008 in staple and non-staple food, clothes, medical care, traffic and communication, and education. In 2008, the per-capita outlay of the household under project impact is RMB8597, including per-capita staple & non-staple food outlay RMB3124, accounting for 36.3 %; per-capita clothes outlay RMB855, 9.9%; per-capita medical care outlay RMB341, 4.0%; per-capita traffic & communication outlay RMB541, 6.3%; per-capita education outlay RMB182, 2.1%; per-capita agricultural outlay RMB2829, 32.9%; other per-capita outlay RMB727, 8.5%. (7) Impact of Land Requisition of Project Construction upon Economic Incomes of the Household The survey and statistics on the impact of land requisition of the project show that totally five households are involved in the impact of land requisition of the project. The analysis proves that the economic incomes of these five households are mainly from the contracting farmland and labor output and the farmland under impact accounts for 33.3% of their total contracting land. The initial estimate reveals that the land requisition for project construction would cause an annual agricultural income decrease of about RMB25.79 million for migrant households, accounting for about 12.9% of total agricultural incomes of the households. 3) Social Status of Women in Project Impact Area and Project Participation In the rural households of project impact area, women enjoy the same right for the land. Both husband and wife usually negotiate and determine the issues of their household jointly. It’s universally known through visit, discussion and questionnaire that the implementation of the project could better the environment and water quality, reduce the diseases, indirectly lower the expenses of the underprivileged for medical treatment and alleviate economic burden of household. After knowing the significance of project construction, the women in the area with indirect project impact have expressed their strong support for project construction. Some hold that the land requisition has severe impact upon their household and expect reasonable resettlement and compensation from the State. 4) Social Status of Minority in Project Impact Area and Project Participation Bayannaoer Municipality is the minority region with Mongolian nationality as principal part while a majority of Han nationality. The residents of Mongolian nationality take part in various aspects of the production and living of the region. Through informal discussions with the Minority Affairs Commission of various banners, we know that each minority in Bayannaoer Municipality has long history, his own religious beliefs, cultures, arts, habits and customs while in long social development, the nationalities have adequately exchanged in the fields such as society, economy and culture and been gradually integrated together. For example, Mongolian nationality has their own language and uses the language inside their nationality while speaks Chinese in talking with the outside. The integration of various minorities is as follows:

��

��

��

Firstly, Chinese is common and official language of various minorities. The minorities i.e. Mongolian nationality, Hui nationality and Manchu nationality in the region use Chinese as written language. On the occasion of major festivals, the people of different nationalities will celebrate e.g. Spring Festival of Han nationality and “Nadamu” Festival of Mongolian nationality. Secondly, the minorities not only enjoy the same right in society, economy and culture as Han nationality but also the preferential policies in education, employment and financial support. Bayannaoer Municipality offers a policy-based preference for poverty-stricken minority villages and minority enterprises. Thirdly, the people of different nationalities keep in close touch, and give no highlight to nationality status. The marriage between different nationalities widely exists. Therefore, the minorities in the project area presently are integrated with Han and other nationalities by and large. Among all households under land requisition impact, one person is the resident of Mongolian nationality. The survey shows the Mongolian resident actively supports the project construction, and expects more development opportunities from the project construction. 10.1.2.2 Analysis on Impact of Project Construction on Local Residents The project construction will have varying impacts on various aspects of local residents including production, living and social economy. Such impacts are divided into positive impact and negative impact. Positive impacts mainly include: y� The construction and operation of the project will improve the level of infrastructure in the project area,

boost up the wastewater disposal capability and industrial water supply capacity of different banners and counties and provide reliable water resources guarantee for the development of regional economy.

y� The implementation of the project can improve the wastewater disposal capability of the enterprises in industrial park, effectively control the wastewater discharged into the drainage channel, and consequently better water quality of various drainage channels indirectly, change negative impact on residents around the drainage channel and finally boost up the health level of residents.

y� The implementation of the project can directly improve water quality of various drainage channels. Better water quality in drainage channels can alleviate the purifying pressure of Wuliangsuhai Lake and improve the ecological environment of Wuliangsuhai Lake, retard the swamping process, and gradually restore the biodiversity of wetlands, enable water quality of drainage system in Hetao irrigation zone to reach relevant national criteria, effectively change water quality of the Yellow River in Bayannaoer Municipality, and finally protect the water system of the Yellow River against pollution damage.

y� The implementation of the project can enable the industrial parks of five banners/counties to have reclaimed water supply and wastewater treatment and recycling works, so as to improve infrastructure level and industrial base service capability of various banners/counties, facilitate the work of attracting foreign investments and better overall investment environment of Bayannaoer Municipality.

y� In construction period of the project, surrounding residents can have the opportunities for providing labor or trade services, so as to increase their incomes. Moreover, the improvement of investment environments in project area can attract more enterprises to develop in Bayannaoer, which as a result, will provide more jobs for the residents in the project area.

Negative impacts mainly include:

y� The construction of the project must unavoidably take over some land for use permanently or occupy temporarily. A field survey and interview show that local villages attach great attention to the land requisition and relocation. Therefore, the work of relevant compensation and resettlement is decisive to the smooth implementation of the project.

y� The construction of the project may cause noises pollution, dust, traffic accident and other potential problems to the residents and enterprises around: for example, the pavement of pipelines may destroy existing infrastructure of the farmers, intercept or occupy some road, hinder the passage of residents in villages and trigger off noises, dust and public security problems during the construction. Moreover, temporary land occupation in the construction period may impact the cultivation of farmland. These issues require some proper construction arrangement by project employer and construction unit in order to minimize the impact upon residents.

10.1.3 Determination of project affected area

10.1.3.1 Measures to reduce resettlement tasks

1) During Project planning and design phase

Land expropriation, removal and resettlement required for the construction of works will inevitably affect the original production and living conditions of the local residents. During the planning and design phase of the Project, when conducting the scheme optimization and comparison, considerations shall be taken to the influence of the construction of the Project on the local society and economy, and such consideration shall be the key factors for optimization and comparison of schemes. For the purpose of reduction of land expropriation and resettlement as for as possible, some effective measures have been taken by the design institute and the Owner of this Project. As far as scheme selection and other supporting facilities concerned, efforts shall be made to keep away from the residential area, to occupy less farm land and to satisfy the local planning and the opinions of local governments.

y� The routing and location of pipelines shall follow the existing roads and planned roads. Efforts shall be made to keep the pipelines away from the concentrated residential areas and to reduce the removal tasks.

y� Attention shall be paid to environmental protection, the land occupation layout, distribution of rivers, landform, geological conditions, prevailing wind direction and other factors of the industrial area shall be considered comprehensively and certain protection space between the industrial area and the residential area shall be set.

y� The construction design shall be optimized and construction period shall be shortened as far as possible. The construction phases shall be arranged reasonably to reduce the impact of construction of works. For example, in general, land expropriation shall be conducted after the crops are harvested.

2) During construction phase

y� Strengthen the public consultation mechanism

Prior to construction of the works, the commencing date and construction schedule shall be publicized by means of notice in the project affected area. The compensation policies relating to land expropriation and resettlement shall be publicized as well to facilitate the supervision by immigrants; During the construction stage, the local materials shall be prior choice. If technology is allowed, local transportation service and labor force shall have priority so as to have the personnel affected by the works benefited from the construction of works.

y� Select reasonable construction time and methods

The construction time shall be combined with the farming time of local farmers and shall be within the slack farming seasons so as to avoid the impact on local farming and production. If any pipe network shall cross any drain ditch, irrigation channel and other Irrigation and water conservancy facilities or houses of local residents, pipe jacking technique will be applied to avoid the reconstruction of water conservancy facilities and houses.

y� Strengthen construction management

The construction organization shall, during the construction, according to the soil treatment plans, carry away the soil and ensure no overloading happens during the transportation, no soil falls from the vehicle. The vehicle shall be cleaned of the mud on the wheel before running out of the construction site to prevent the falling of soil from the vehicle. During the construction, the excavation of channels, the trumpet of the vehicle, the sound of engine, the sound of concrete mixer and the sound of road roller will cause noise. For the purpose to soften impact of such noise on nearby residents, the construction in the area 200 away from the residential houses is prohibited during o’clock 11 in the evening and o’clock 6 in the next morning. Meanwhile, priority shall be given to low-noise construction equipment and methods. If construction at night is required and will affect the sound environment near the residential area, then noise reduction measures shall be taken on the construction machines, meanwhile, temporary equipment such as sound barrier may be established near the construction site or the concentrated residential area so as to guarantee the quality of sound environment in the residential area.

y� Civilized construction and environmental protection are encouraged.

Construction organization shall make efforts to reduce the impact of construction on nearby residents, plants, and school, etc. Civilized construction is encouraged. Liaison meeting between construction

organization, street administration authority, and owners shall be organized to conduction in timely manner consultation on the issues such the impact of construction on environment; The Owner of this Project and the construction organization shall contact the local environmental protection authority, and shall clear off the domestic wastes on the construction site. The construction organization shall strengthen the instruction for construction personnel about avoidance of littering so as to guarantee the quality of of the living and working environment of workers.

3) Land expropriation, removal and resettlement plans and implementation phase

y� The fundamental data shall be collected adequately for the analysis and study of local social and economic conditions. Feasible resettlement plans shall be formulated by combination with the local conditions to reduce the impact on the construction of works and to ensure that the living level of personnel affected by the Project will not be lowered by the construction of this Project.

y� Internal supervision and outsider independent supervision shall be strengthened, smooth and efficient information feedback channels shall be established and the time of information treatment shall be shortened so as to ensure that any problem during the construction of this Project will be solved in time manner.

4) After completion of Project

For the purpose to reduce the unfavorable impact of this Project on the production and life of local residents during the construction of this Project and after completion of this Project, following measures will be taken after completion of this Project:

y� After completion of this Project, all wastes and abandoned materials, equipment and machines on the construction site shall be cleaned properly. The areas excavated during the construction shall be leveled timely.

y� During operation of this Project, the main pollutants mainly include noise and odor. Therefore, the wastes generated during the operation of wastewater treatment shall be cleaned off or buried timely, the rubbish fallen on the entrance access and road shall be cleaned out so as to prevent such rubbish being raised by the wind. Meanwhile, proper trees, grasses and other greening measures shall be taken; management and maintenance shall be strengthened. Currently existing trees and tree belt shall be kept as far as possible to beautify the environment, purify the air and reduce the noise.

1) Impact of land expropriation on Wulatehouqi County

Totally 195.00 mu of uncultivated land (wild grass land) in Hongqi Village, Qingshan Town will be expropriated for the water supply work and wastewater treatment and recycling work in Wulatehouqi County Industrial Park. No farmland will be expropriated. According to the on-site investigation, the main income sources of local residents are stock raising and agriculture. At present, all villagers have certain number of farmland. Stocks are raised in the pasture. No impact on the agricultural production will be caused by the expropriation of uncultivated land.

2) Impact of land expropriation on Wulatezhongqi County

Totally 157.50 mu of farmland in Muyanghai Farm will be expropriated for the construction of water supply work and wastewater treatment and recycling work in Ganqimaodu Industrial Park. According to the onsite investigation in the planned migrant group, the land in Muyanghai Pasture belongs to state-owned land and land affected is small, therefore the degree of impact is low. The land affected only covers 0.44% of total farmland. Meanwhile, the users of the land expropriated will be afforded new land, therefore no impact will be caused by the land expropriation on the normal agricultural production in the Pasture.

3) Impact of land expropriation on Hangjinhouqi County

Totally 38.00 mu of farmland in the Culturing Plant in Shawan Village, Shanba Town, Hangjinhouqi County will be expropriated for the construction of Sanpaigan regenerated water work. According the on-site investigation, the average farmland of the residents in the Yangzhi Sub-vilage in Shawan Village is 7.39 mu, and

6.57 mu after land expropriation. The farmland affected by the land expropriation covers 11.18% of total farmland. Comparing with other villages affected, the degree of impact is high. Totally 5 households (Shan Baolin, Wang Fugui, Chen JIinyong, Wang Erhu, and Hao Zhen) and 22 persons of Yangzhi Sub-village of Shawan Village are affected by the land expropriation. The planning team has conducted detailed investigation concerning these 5 households affected. According to the analysis, the degree of impact on all farmlands of these households reaches more than 20%. The degree of impact is high. Households affected by land expropriation are shown in Table 10.1-8.

4) Impact of land expropriation on Wuyuan County

Totally 37.50 mu of uncultivated land in the first sub-village of Jiucheng Village, Longxingchang Town, Wuyuan County will be expropriated for the construction of Qipaigan regenerated water work. According to the on-site investigation, Longxingchang Town is the original location of Wuyuan County government. The residents of Jiucheng Village are involved not only in agricultural production, but also secondary industry and tertiary industry. Only small number of uncultivated land in the first sub-village is affected by the land expropriation, therefore, on impact will be caused on the production and living of local farmers.

5) Impact of land expropriation on Wulateqianqi County

Totally 165.00 mu of uncultivated land in Zhongtan Farm in Wulateqianqi County will be expropriated for the construction of wastewater treatment and recycling work in Wulateqianqi County Industrial Park. According to the on-site investigation, the land affected by land expropriation belongs to state-owned land, and belongs to uncultivated land, neither the production and operation of the farm, nor the living and production of farmers in nearby villages will be affected by the land expropriation.

10.1.5.2 Analysis on impact of temporary land occupation

Totally 2839.55 mu of land will be temporarily occupied by the pipeline and the construction of this Project, including 253.55 mu of farmland, 2585.70 mu of uncultivated land. According to the data provided by the owners of each work and the on-site investigation, the construction of pipeline will be completed in 30-60 days. Except the pipeline crossing Sanpaigan, Qipaigan and Yihe Channel, no other pipeline will cause impact on roads or channels. Meanwhile, all pipelines are set away from the residential area to some extent.

For the purpose to avoid and mitigate the impact on the channels and production of local residents by the construction of pipelines the Owner of this Project will compensate properly the residents whose production is affected by land expropriation against the crops, meanwhile, the construction will be arranged at spare time of local residents. For the pipelines crossing drain channels, irrigation channels and other water conservancy facilities or houses of local residents, pipe jacking will be applied to avoid the repeated construction of water conservancy facilities and houses. In addition, the Owner of this Project will help farmers carry out land leveling or land improvement by taking advantage of the transportation of earthwork.

Meanwhile, for the purpose to reduce the impact of excavation of road and deposit of earthwork on the nearby environment and local residents, the construction organization will establish retaining wall around the construction site to prevent the dust flying with the wind. Owner of this Project will define the modes of temporary use of land and recovery requirements, etc, during execution of construction contract with the Contractor.

In addition, according to the on-site investigation by East China Institute, the construction of these works is supported by local residents. After they are informed of the impact on their living and production and are

compensated in accordance with the law, almost all residents accepting the investigation show that they will conquer the impact by the construction and support the construction of this Project.

10.2 Migration and resettlement plans

The preparation of the migration and resettlement plans concerning this Project and the future implementation will follow relevant laws and regulations of Inner Mongolia and the requirements of OP4.12 Business Policy of World Bank. The implementation of land expropriation, removal and resettlement tasks will strictly follow the resettlement compensation standard and relevant policies. If change happens during implementation, the Owner of this Project will prepare corresponding special reports to the World Bank. Such report may into operation only approved by World Bank.

10.2.2 Resettlement policies applicable to this Project

According to above mentioned national and local laws, regulations and relevant policies of World Bank, combined with the actual conditions of the area affected by the Comprehensive Project, and based on the adequate consultation with the people affected, the Resettlement Office of this Project has formulated following resettlement plans applicable to this Project.

10.2.2.1 Compensation for various kinds of land affected

y� The local governments of the area affected by this Project is preparing the uniform standard of annual production value of this region, however, such standard has not yet approved by Inner Mongolia Autonomous Region, therefore, the production value per mu of farm land applied for calculation of land compensation will be determined based on relevant statistic data and combined with the on-site investigation. The magnification of compensation for farm land expropriated is 10 times and that of subsidy for resettlement is 6 times.

y� If there are crops in the land expropriated, the compensation for crops will be 1 time of the annual production value of this tract of land; no compensation will be given for uncultivated land such barren mountain, wild land, and barren sand

y� Compensation for fruit trees will be determined according the type, age, and size o trees. Since only timber trees are affected by the land expropriation, referring to the nearby project completed recently, the compensation standard for mature trees is 100Yuan/tree and 50Yuan/tree for baby trees.

y� Compensation for temporary land occupation (wasted soil yard, access and construction camp, etc) will be calculated according to the annual production value and the actual occupation time. One-year term will be applied if the time is less than 1 year. The construction organization shall be responsible for recovery of temporary occupied land.

10.2.2.2 Resettlement of rural residents affected

y� If the village or sub-village committee has adjusted the land or explored the land to have the household whose land is expropriated obtain new land or other production materials, then the land compensation and resettlement subsidy shall be managed and utilized by the village committee. If the village or sub-village committee has not adjusted the land or explored the land and the households affected do not obtain any production materials, then the village committee shall pay the resettlement subsidy to the households whose land is expropriated, the land compensation will be managed and utilized by village committee, and will be distributed and utilized according to the decision of general meeting of villagers.

y� During construction, new employment opportunity will be given, and priority will be given to the people affected by this Project. These employment opportunities will benefit the local residents.

10.2.2.3 Public consultation and information disclosure

y� Public consultation meeting

Irregular official consultation meeting will be held by the Resettlement Office. Resettlement Office will organize such meeting irregularly according to the actual conditions of land expropriation and resettlement. The theme, scale, participants of the meeting will be determined as the change of demands, and will be supervised by independent outsider supervising institute.

y� The use plans of land funds will be made via public consultation, and may be put into implementation upon approval by the general meeting of villagers.

y� Resettlement information system based on computer will be applied to strengthen the management of resettlement and ensure the consistence between the implementation of resettlement and the policy concerning resettlement. Resettlement information will be publicized from time to time to set up a bridge between the Resettlement Office and the people affected. Feedback of immigrants will be collected and any possible bias will be remedied in timely manner.

10.2.3 Compensation standard

10.2.3.1 Compensation standard for land acquisition and expropriation

1) Annual production value of farmland

The local governments of the area affected by this Project is preparing the uniform standard of annual production value of this region, however, such standard has not yet approved by Inner Mongolia Autonomous Region, therefore, the production value per mu of farm land applied for calculation of land compensation will be determined based on relevant statistic data and combined with the on-site investigation. The production amount per mu of farmland will be calculated as per the average production amount per mu in recent three years from 2006 to 2008. According to the on-site investigation and combined with the similar project completed recently, the price of farm products will be calculated as per the price of second quarter of 2009. After calculation, the average annual production value of farm land in Wulateqianqi County, Wulatezhongqi County, Wulatehouqi County, Hangjinhouqi County and Wuyuan County in recent three years is 1129 Yuan/mu, 765Yuan/mu, 810Yuan/mu, 1331Yuan/mu and 1384 Yuan/mu respectively.

2) Compensation standard for rural collectively-owned land

According to the relevant provisions on land compensation provided in “Implementation Measures of the Land Administrative Law of the People’ Republic of China”, the compensation for land will be 6-10 times of the average annual production value of recent three years and the resettlement subsidy for each rural resident will be 4-10 times of average annual production value of farmland of recent years. According to the investigation by the

Owner and related designer of this Project, the magnification of compensation for farm land expropriated is 10 times and that of subsidy for resettlement is 6 times. The sum of these two items is 16 times of production value per mu of farm land.

Therefore, the compensation standard for collectively-owned farmland expropriated in Hangjinhouqi County is 1331oYuan/mu, resettlement subsidy is 7986Yuan/mu, the total of the two items is 21296Yuan/mu.

The compensation standard for uncultivated land expropriated will refer to the similar project completed recently in each banner on temporary basis and the compensation for crops in the farmland expropriated will be calculated as per the production value of crops in the first quarter. According to the on-site investigation, the banners and counties involved in the rural collectively-owned land expropriated by this Project are Wulatehouqi County, Hangjinhouqi County and Wuyuan County respectively. The compensation standard for expropriation of rural collectively-owned land in each banner (county) is shown in Table 10.2-2.

3) Compensation standard for state-owned land

The compensation standard for construction land in Ganqimaodu Port in Wulatezhongqi County will be determined according to the consultation between the Owner and the industrial park involved in the construction of this Project. According to the data provided by Owner and the on-site investigation, the compensation standard is 9167Yuan/mu.

According to the introduction made by local land administration authority, Owner shall pay land compensation for paid use of farmland or uncultivated land in state-owned land, and shall pay royalty for use of new construction land; If the land belongs to profit-oriented mining and industrial enterprises, then Owner shall pay state-owned land grant fees according to “Minimum Price Standard for Sale of State-owned Industrial-purpose land”, which may be deducted with the land compensation and royalty for use of new construction land paid in advance. Therefore, the only thing is to make up the deficiency.

Since the Project belongs to infrastructure construction project, and is a non-profit project, for the sate-owned land in Zhongtan Farm and Muyanghai Pasture involved in this Project, only land compensation and royalty for use of new construction land are included currently. According to site investigation and calculation, since there is on state-owned land compensation standard in effect in each banner (county) involved in this Project currently, the compensation standard for state-owned land in Wulatezhongqi County and Wulateqianqi County will refer to that for rural collectively-owned land, that is, the compensation standard for the state-owned farmland in Wulatezhongqi County is calculated by 16 times, that is, 12240Yuan/mu, and that for crops takes 765Yuan/mu. Details of compensation standard for state-owned land expropriation in each banner are shown in Table 10.2-3.

The temporary land acquisition involved in this Project concerns two types land, farmland and uncultivated land. According to the opinions of Owner and the villages and sub-villages affected, compensation shall be made for temporary occupation of various types of land. The construction organization shall recover the land after completion of this Project.

Since the comparatively short construction period, the compensation of acquisition of farmland mainly involves two items, compensation for crops and costs for land recovering works. The compensation for crops is calculated as per the production value per year and costs for land recovering works is calculated as per 25—Yuan/mu. Compensation for uncultivated land is calculated as per 300Yuan/mu. Compensation standard for temporary occupation of land in each banner and county is shown in Table 10.2-4.

Compensation for fruit trees will be determined according to the type, age, and size o trees. Since only timber trees are affected by the land expropriation, referring to the nearby project completed recently, the compensation standard for mature trees is 100 Yuan/tree, and 50 Yuan/tree for baby trees.

The above compensation standard is made according to the relevant national and local polices and regulations, combined with the requirements of World Bank, and has been recognized by the local residents and relevant organization.

10.2.4 Resettlement and compensation plans

Under the coordination and support by Bayannaoer Municipal government, the Bayannaoer Hetao Water Co., Ltd, each level of government involved in this Project, and East China Survey and Design Institute have conducted the planning of resettlement works of the Comprehensive Treatment Project according to current policies, laws, and regulations in effect and the requirements of World Bank on Resettlement based upon the planning and schemes of resettlement delivered by each town, township and village affected by this Project.

10.2.4.1 Objective and tasks of planning

1) Objective

According to the characters of impact caused by this Project, the objective of resettlement planning is to: mitigate the impact on the living and production conditions of migrants, and make the production and living level of them not lower than the original level or be improved to some extent.

2) Tasks

According to the investigation and statistics, the no household will be involved in house removal of this Project. For the uncultivated rural collectively-owned land of villages and sub-villages and the state-owned farm expropriated for this Project, cash compensation and resettlement subsidy will be offered according to relevant policies and the opinions of relevant villages and sub-villages. For the five households, totally 22 persons, affected by the expropriation of farmland in Shawan Village, Shaba Town, Hangjinhouqi County, cash compensation combined with land adjustment within the villages and sub-villages will be applied.

10.2.4.2 Production and resettlement recovery planning

Based upon the full consultation with each village, organization, representative of villagers and immigrants affected, to respect the choice of majority of immigrants, cash compensation will be applied.

According to the on-site investigation, except a small number of villagers, almost all of the villagers investigated prefer to the cash compensation for settlement. The final resettlement plans are determined according to the opinions of majority of immigrants. If any immigrant chooses to continue to live on farming, the Owner of each work in each banner (county) will allocate flexibly the collectively-owned land for them or help them obtain the land from those households who are unwilling to live on farming.

According to the resettlement means by cash compensation, the compensation for land will be paid via payment channel directly to each relevant village, organization and individual affected for their free disposal The resettlement plans for each village are detailed respectively as follows:

From Table 10.2-5, the impact on the living and production and the general income of households affected by land expropriated is not so significant. For the purpose of preparing reasonable and practicable production and resettlement recovery plans, the planning team has conducted informal discussion with the villagers during on-site discussion, to fully understand the demands of immigrants. It is found in the discussion that among the five households affected, only those at the age of 50-60 are involved in traditional agricultural production, meanwhile, it takes only three km from Shawan Village to Shaba Town, the location of government of Hangjinhouqi County, large number of young labor force from the village works in Shaba Town and stay in city as worker in most of time of a year and return to village to do farm work in busy season, therefore, the degree dependence of this young labor force on land is low. During the discussion, certain number of immigrants expresses their aspiration to do business or investment, and is

troubled for lack of money, therefore, for the land compensation means; all five households choose the cash compensation. They want to expand their accumulation of capital from the land compensation, which will afford them opportunity to do business in secondary and tertiary industry in the future. For the impact on their income for the loss of land, they will spend some of the land compensation to open up new farmland in the village to increase the income. Therefore, after soliciting the opinions of relevant sub-villages and immigrants, the villagers committee decides, after mutual discussion, that cash compensation will be applied; the land compensation will be transferred directly to the villagers. In addition, Shawan Villager Committee commits that if resettled households request to obtain new land, Villager Committee will help the regional adjustment of farmland in the sub-village.

y� Zhongtan Farm and Muyanghai Pasture

Totally 165.00 mu and 157.50 mu of state-owned land in Zhongtan Farm and Muyanghai Pasture will be expropriated for the wastewater treatment and recycling work in Wulateqianqi County Industrial Park and wastewater treatment and recycling work in Ganqimaodu Pork Industrial Park respectively. No house will be removed. According to the relevant regulations of Bayannaoer, land compensation will be paid directly to Zhongtan Farm and Muyanghai Pasture.

4) Temporary occupied land recovery plan

Temporary occupied land for construction refers to the land lent in temporary manner within construction period. For this Project, it refers to the land occupied for construction of pipelines and no house will be removed. After completion of this Project, the Owner of this Project shall recover such land according to relevant requirement at the expense of land reclamation fees. The compensation for crops in the land temporarily occupied for the Project will be paid directly to the owner these crops.

During the design, the design institute of this Project shall try best to lay the pipes along the existing roads or channels so as to avoid the disturbance on the normal life of residents.

5) Management and application of compensation

According to the Measures of Inner Mongolia Autonomous Region on Implementation of the Law on Villagers’ Committee of the People’s Republic of China and the Implementation Regulation on Land Administrative Law, the application scheme of compensation for land expropriation must be submitted by Villagers’ Committee for discussion by the Meeting of Representatives of Villagers. For those who will not be resettled uniformly, their resettlement subsidy will be paid directly to them.

According to above regulations, the application schemes of the land compensation are determined after fully discussed by Villagers’ Committee based upon the opinions solicited from the immigrants:

If farming households are affected by land expropriation, the land compensation will be paid to the immigrants whose farmland is expropriated in full-amount manner. If no household is directly affected by the land expropriation, the land compensation will be paid directly to relevant sub-villages and will be used for future construction of infrastructure. The compensation for attachments to the land or crops will be paid directly to their owners. The compensation will be paid by the land expropriation organization to relevant owners via a payment channel.

6) Protection of women’s rights and interests and participation in Project

y� In the villages affected, women have participated in the economic activities extensively. They do farm work, and some work part-time for others. The economic activities involved by women have became the important source of their households, meanwhile, in the daily life, they undertake more household duties. The land expropriation and house removal will cause loss to the livelihood of women and increase the economic difficulty facing the women. Therefore, it is very important to take the gender issues into consideration in the implementation of resettlement plans. In this Project, the main problems facing the women are the payment of compensation and recovery of production. The Project Office will, together with local governments and NGOs, make efforts to promote the gender equality and increase the income of women.

y� Create employment opportunity for women. During the construction of this Project, employment opportunity will be given each year. The service work relating to the construction fits the local women better; therefore propriety will be given to women for such posts. Since unemployment is the main cause of the poverty of women, these employment opportunities will benefit them to large extent. Safeguard the participation by women. The participation in the discussion by women must be ensured. The special demands of women must be taken into consideration in all resettlement plans. All kinds of information shall

be disclosed to women. The Project Office will organize meeting of representatives of women during implementation of this Project to discuss and solve the problems facing the women during resettlement.

y� Local governments and resettlement office will ensure that women enjoy same rights with men with respect to land and property. The divorced or widowed women still have the right to obtain land and enjoy land compensation. The Resettlement Office will require all of the co-owners of land or house to sign their names.

y� Eliminate the gender discrimination and encourage the entrepreneurship of women The Project Office is established partnership with local governments and NGOs to make efforts to increase the opportunity and living quality of women. First, Resettlement department must employ female employees to help women and solve problems facing women in all aspects of resettlement, To help women participate extensively in the resettlement planning, management and operation, employment and income recovery and other activities; Secondly, local governments, resettlement office will cooperate with NGOs to eliminate the gender discrimination existed in investment environment, and to encourage the women to participate in the work of official organization to promote the development of private enterprises run be women and exert fully the potential of women.

7) Organization and management of resettlement.

The implementation of resettlement plans will be under the leadership of leaders’ team of municipal project coordination teams. All banners (counties) affected by the construction of this Project have designated special personnel to form the Project Office to be responsible for the preparation of resettlement policies, the relocation of immigrants and the publicity, mobilization, organization and implementation of resettlement activities. Meanwhile, the Project Office will be main channel for immigrants to express their concerns. The Project Office shall hear, collect and classify the opinions and problems of immigrants in timely and adequately manner, and report such opinions and problems timely to higher department or competent authorities, meanwhile feed back the treatment results to the immigrants in timely manner.

11.2.2 Contractual Requirement on Environmental Management In project construction, the contractor will play a key role in environmental management, pollution control and the prevention measure implementation. As a result, the requirements for the contractor are as follows: y� Qualified contractor is selected for ensuring effective implementation of environmental

management plan; y� The contractor and construction supervisor must receive the trainings on environment protection

and environment management before construction; y� The environmental impact reducing measures in construction period in above should be included

in the bidding document of the contractor and finally in the construction contract as contractual requirement of project contractor.

y� The contractor should monitor its environment activity, daily or weekly submit an environmental performance record report. The project office and the construction supervising team will supervise and verify these records.

y� The contractor should provide at least one full-time employee liable for the environment for each sub-project. These employees liable for environment must receive the training as scheduled so as to be competent for their job.

y� In the construction, the contractor should communicate and negotiate with the people in the region of the project, set up bulletin at each construction unit for announcing specific construction activities, time, contact and telephone so that the public can present their complaint or proposal for the construction activity.

y� A deposit for environmental management and etc. should be planned in the contractual funds of the project of the contractor as per annual budget, with a proportion of about 3% of the budgetary funds.

11.2.3 Information Exchange and Solution to Non-conformity Case In environment monitoring, information needs to be disclosed to the field environment supervisor, environmental management manager of enterprise and project office. To focus the attention of management on the most important issues, the non-conformity of the project is divided at three levels as follows as per the difference of importance. y� Level 1: definition: the non-conformity status is defined as non-conformity with the original

requirement while is deemed to have no short-term impact on very important resources. The repetitive occurrence of Level 1 may cause the appearance of Level 2 if not properly handled. Measures: proper cooperation and regular communication can deal with the case of Level 1. For example, the construction unit discusses with the employees of operating unit. As a result, remedy

measures can be implemented soon. The formal communication mode is typically a weekly report that environment supervising engineer submits to environmental management manager and field building manager of enterprise.

y� Level 2: definition: the non-conformity status doesn’t produce an obvious damage or inconvertible impact for the sensitive and important resources while needs immediate remedy and field disposal for preventing above-said impact. The repetitive occurrence of Level 2 may cause the appearance of Level 3 if not properly handled. Measures: In case of the event of Level 2, environmental management manager of the enterprise must report to environment manager of project office and field building manager on the day of occurring and remedy measures should be defined as soon as possible. Generally, remedy measure must be submitted in one week upon the occurrence.

y� Level 3: definition: the level includes a damage to sensitive target in focus or predictable and instant damage. Special behaviors prohibited internationally are also included in Level 3. Measures: In case of the event of Level 3, environmental management manager must report to environment manager of project office and field building manager on the site immediately and remedy measures should be defined as soon as possible. Generally, remedy measure must be submitted in three days upon the occurrence except special cases in need of more time. If necessary, the environmental management manager of the enterprise can require the building manager to stop some special works in order to protect the resources before implementation of remedy measures.

11.4 Estimates on Environmental Management Expenses and Source of Capital 11.4.1 Budget Distribution The implementation of EMP measures involves many units. As a result, different sources of capital exist. Most environmental protection activities are engineering measures. Therefore, the construction unit and operating unit of the project should provide the expenses and include in their engineering costs, which are defined and listed in their bidding documents. The expenses in EMP are mainly used in environmental management in construction period and operation period, primarily including: environment monitoring expenses, environment supervisor expenses, personnel training expenses, running costs of environmental management institutions as well as risk preventing expenses in some projects. EMC activities will be included in the international project management expenses of PMO and PIUs. So does the monitoring of water quality, atmosphere and noises, CSEE and EFSI. The CSEE monitoring and supervising activity is part of building and supervising expenses. Local environment monitoring stations will monitor water, noises and atmosphere in the operation of project as authorized by project employer, where project employer pays the monitoring expenses. If regular monitoring of local environmental protection authorities synchronizes with the project, their data of regular monitoring can be used. 11.4.2 Capital Source and EMP Budget

12 Conclusion of Environmental Appraisal 12.1 Relevant Policies and Conformity with the Planning The reclaimed water supply works and wastewater treatment and recycling works of the project belong to “brackish water, bad quality water, seawater development and utilization and seawater desalting works” and “three wastes” integrated utilization and treatment works within the category of encouraging environmental protection and integrated resources saving and utilization in the national guide inventory of the industrial structure adjustment (Version 2005) respectively; the sea area treatment works of the project, a water environment treatment works aims at protecting & restoring wetland function of Wuliangsuhai Lake, and is implemented in buffer zone and test area, instead of core area. As per Circular of General Office of the State Council for Strengthening Wetland Protection Management (GOSC [2004] No.50), wetland protection & wetland function restoration as one priority in improving living conditions and building a well-off society in all-around way should be strengthened. Sea area treatment works of Wuliangsuhai Lake complies with the laws and statutes of the State. According to the environmental appraisal policies (OP 4.04) of the World Bank, it supports the protection, maintenance and restoration of natural habitat and its function, and assists and expects the borrowing party in taking defense measures in natural resources management for guaranteeing the sustainable development of environment. It provides assistance funds for natural habitat and ecologic function protection project helpful for the development of the country and region, and advocates restoring and rebuilding work for natural habitat with deteriorating environment. In the “11th Five-Year Plan” period, the economic and social development planning of Bayannaoer Municipality brings forward the construction of resources saving & environment friendly society. On one hand, integrate water resources, plan and utilize the water of the Yellow River, surface water, underground water and rainwater in unified way, and try to realize the circulated use of water resources. On the other hand, strengthen the protection and treatment of water environment and construction of urban wastewater disposal facility and auxiliary pipelines, and gradually realize the emission of urban and industrial wastewater in conformity with the standards, and cut off the pollution source for the Yellow River and underground water. Moreover, plan treatment works of Wuliangsuhai Lake, urban road and pipeline, water supply and drainage, garbage disposal and wastewater treatment works as key infrastructure construction projects in the “11th Five-Year Plan” period. The implementation of various works of the integrated water environment treatment projects of Bayannaoer Municipality with WB loan complies with overall urban planning and city planning with regard to the site selection, and is also important measures for realizing the urban target of overall urban planning and city planning of Bayannaoer Municipality, water resources configuration and the environment protection targets. In sum, the construction of the project complies with not only industrial policies, laws and statutes of the State and environmental appraisal polices of the World Bank for the loan project but also the national economy and social development planning, overall urban planning and city planning of Bayannaoer Municipality. 12.2 Analysis on Water Resources Balance Total annual average water resources in Bayannaoer Municipality in many years are 5.5742 billion m3, including surface water resources 4.7791 billion m3. Water resources are mainly used in industrial and agricultural production, domestic and ecologic water consumption of urban and rural residents. As per the water resources allocation plan approved by the State and the autonomous region, the quota of water that Bayannaoer Municipality imports from the Yellow River is 4 billion m3. Due to historic reasons and actual situation of agricultural water consumption of Hetao irrigation area, annual average quantity of water imported from the Yellow River in many years is 4.6748 billion m3. At present, Hetao irrigation area imports 674.8 million m3 water of the Yellow River more than the quota annually. The water demand and supply of the primary, secondary, third industries, domestic purpose and ecologic environment are predicted. The result shows that the annual water demand in 2010-2030 is 4.0965025 billion m3, and the water supply available includes the water from the Yellow River, underground water and reclaimed water. The annual average supply of water is predicted as 4.0965025 billion m3. The analysis on water quantity balance of Wuliangsuhai Lake reveals that in case of the net quantity of water that irrigation area discharges into Wuliangsuhai Lake more than 515 million m³, present ecologic water consumption and the water area of Wuliangsuhai Lake can be kept. After the project is implemented in 2015 and water-saving measures are taken in agriculture, if the water break of farmland decreases by 10%, the water break of general trunk ditch as well as Bapaigan and Jiupaigan is 415 million m3 and 62 million m3 respectively. After the project is implemented, if 31 million m3 is reused, water return from general trunk ditch and Bapaigan and Jiupaigan into Wuliangsuhai Lake is 446

million m3. To maintain the ecologic water demand of Wuliangsuhai Lake at 515 million m³, it requires Shiganqu to provide makeup water of 69 million m³ in ice flood season. According to the preliminary engineering design of the works of Inner Mongolia for diverting the flood of the Yellow River to Hetao irrigation area & Wuliangsuhai Lake in the emergency ice flood control proposal, the flood diverting amount is defined as 161 million m3, including 100 million m3 for Wuliangsuhai Lake and 61 million m3 for the trunk channel of Hetao irrigation area and natural lake in the north of irrigation area. Therefore, the flood diversion in ice flood season can ensure the water makeup quantity of Wuliangsuhai Lake; the preliminary design of the project has already won approval of the Department of Water Resources of Inner Mongolia Autonomous Region (Approval for Preliminary Engineering Design of the Works of Inner Mongolia for Diverting the Flood of the Yellow River to Hetao Irrigation Area & Wuliangsuhai Lake in the Emergency Ice Flood Control Proposal IWRCM [2009] No.170). Moreover, the water import through Shiganqu in ice flood season isn’t included in the quota, and complies with the national and local regulations as ecologic makeup water of Wuliangsuhai Lake. 12.3 Appraisal Result of Present Environment Quality 12.3.1 Present Situation of Air Environment Quality The mean value per hour and daily mean value of SO2, NO2 at each monitoring spot of the sub-projects can meet the requirements of relevant standards; the specific pollutants such as NH3 and H2S relating to this project can meet the requirements of environmental quality standard and the indicators of each item have not been detected; the daily mean value of TSP and PM10 at most monitoring points of each sub project exceeds the environmental standard, of which the over-limit ratio in Wuliangsuhai Lake Area reaches 100% at the most, with particle pollution at certain extent. 12.3.2 Present Situation of Quality of Surface Water Environment The water quality in 3rd Drainage Canal and 7th Drainage Canal is polluted seriously, and the major contamination index such as chemical oxygen demand, (COD), biochemical oxygen demand (BOD), total nitrogen, ammonia nitrogen and total phosphorus exceed the standards; compared with the quality of water environment in 3rd Drainage Canal and 7th Drainage Canal, the pollution water quality in General Drainage Canal is relatively light, where the major contamination index is chemical oxygen demand, (COD), biochemical oxygen demand (BOD), total nitrogen, ammonia nitrogen and total phosphorus and so on, of which the pollution of COD and total nitrogen is serious; the quality of the water environment in General Drainage Canal is gradually being improved. The contents of heavy metals such as cadmium, mercury and lead in 3rd Drainage Canal, 7th Drainage Canal, General Drainage Canal, Yongming Reservoir in Wulatehouqi County, Wangliuhao Reservoir in Wulateqianqi County and Wangba Reservoir in Wulatezhongqi County are relatively lower on the whole, meeting the national standard for quality of surface water environment. Water in rainy season in Wuliangsuhai Lake is mainly featured by organic pollution and the dissolved oxygen, CODC, BOD5, NH3-N and TP at the monitoring sections partially exceed the standards, and pollution caused by eutrophication pollutants such as nitrogen and phosphor is relatively light in rainy season; while in dry season, CODC, BOD5 and total nitrogen at the monitoring sections all exceed the standards, and dissolved oxygen, NH3-N and TP partially exceed the standards, so the water pollution is extremely serious. In addition, the water quality at the west part is worse than that at the east part in Wuliangsuhai Lake. 12.3.3 Present Situation of Quality of Ground Water Environment The quality of groundwater at each planned plant site of the wastewater disposal and reuse engineering and water supply engineering of reclaimed waterin processing parks exceeds the standards mainly in inorganic indicators such as ammonia nitrogen, sulphate and total hardness; no heavy metal exceeds the standards, and the groundwater at each planned plant site of each project coincides with the characteristics of the groundwater quality of the entire region, having a higher mineralization of water quality and some exogenous pollution at certain extent. The water quality of the confined water (pumping well) in groundwater around Wuliangsuhai Lake is better and the water quality of the underflow water is worse; some of the indicators of the groundwater at Branch Farm 12, Branch Farm 9, Branch Farm 1, Work Area 5, Branch Farm 6, and Branch Farm 3 exceed the standards, of which ammonia nitrogen is extremely exceeding the standard, Chlorides at Work Area 5, Branch Farm 6, and Branch Farm 3 exceed the standard. Wuliangsuhai Lake has a remarkable impact on the groundwater environment around it, especially on the water quality of the underflow water. 12.3.4 Present Situation of Quality of Acoustic Environment

The quality of acoustic environment at each planned plant site of the wastewater disposal and reuse engineering and water supply engineering of reclaimed waterin processing parks is better, except that the noise value within the east site boundary of the wastewater disposal and reuse engineering of Wulateqianqi County Processing park is 50.4 dB (A) at night, values at other monitoring points doesn’t exceed the standard limits of Class II in Environmental Quality Standard for Noise (GB3096-2008). The daytime equivalent noise level at the villages around Wuliangsuhai Lake is 39.6�50.6dB(A) and the night time equivalent noise level is 30.8�47.0 dB(A); except that the night time noise at Branch Farm 3 exceeds the standard, values at other monitoring points can meet the functional requirements of Class I acoustic environment in Environmental Quality Standard for Noise (GB3096-2008). 12.3.5 Monitoring results for sediment The heavy metals in sediment of Wuliangsuhai Lake don’t exceed the limits in Control Standards for Pollutants in Sludge from Agricultural Use. 12.3.6 Present Situation of Ecological Environment The annual mean biomass of zooplankton in Wuliangsuhai Lake is 3.6240 mg/L, varying from 0.220 7 to 7.809 9 mg/L, belonging to eutrophy type; the reducing order of the mean biomass of zooplankton is copepods>nauplius larva>rotifer >Cladocera> protozoan; the mean biomass of zoobenthos in Wuliangsuhai Lake in summer and fall is up to 71.672 g/m2, belonging to eutrophy type, the reducing order of the mean biomass of zoobenthos is chironmus larva> mollusc >oligochaeta; the PCQ value in Wuliangsuhai Lake is 6.6, belonging to eutrophy type. The PCQ value in small lake is 7.3, belonging to super-eutrophy type; comparing the results of ichthyologic survey this time with the historical results, the species and quantity of have reduced remarkably; some species such as snail carp, grass carp, Leuciscus waleckii, Xenocypris argentea Gunther and plaice have already been extinct; the wetland environment in Wuliangsuhai Lake is increasingly worsening, though birds suitable for swamp environment are gradually increasing, the birds species suitable for vast waters are relatively decreasing. 12.4 Appraisal Result of Environmental Impact 12.4.1 Environmental Impact in Construction Period (1) Appraisal Result of Water Environmental Impact The main pollutants for water system in construction period are: domestic wastewater of construction personnel and construction wastewater. With proper measures, the impact upon environment can be controlled within allowed limit. A backhoe sludge excavating ship & bucket-grab sludge excavating ship are used in the grid waterway works of Wuliangsuhai Lake for excavating grid waterway, and can effectively reduce pollutants and secondary pollution of SS scattering around. Moreover, sludge excavating ship operates at fixed position with little disturbance for the substrate sludge of sea area, where the leakage of substrate sludge is little, and the construction impact on water environment is within the scope of 50-60m. The sludge excavation works will promote the removal of pollutants such as nutritional salt and heavy metal and exercise a negative impact on water environment quality. In the dredging period and short time after the dredging is over, the content of total suspended solid, poisonous heavy metal ion, nitrogen and phosphor nutritional salt in water will increase, and the transparency of water will decline. Such environmental impact features some duration. However, one year after dredging, the quality of water system improves, and various indicators are lower than the level before dredging. As a result, the substrate sludge excavation will promote the improvement of water quality of the lake. (2) Conclusion of the Analysis on Atmospheric Environmental Impact On the construction stage, air pollution mainly comes from the flying dust of construction vehicle in running, pile-up yard and agitation as well as tail gas of vehicles. The analysis and preliminary estimate prove that the flying dust in the

construction will cause some impact upon the resident, school, enterprises and government-sponsored institutions around the construction site and the construction personnel, in which the impact upon construction personnel is the biggest. However, after necessary measures taken, the impact of flying dust in construction can be minimized. Moreover, such impact is temporary. After the construction is over, the impact will decline rapidly with the implementation of greening and replanting works and even disappear. The tail gas of construction machine and transport vehicles includes nitrogen oxide, carbon monoxide and hydrocarbon mainly. Such pollutant can easily be diluted and scattered due to less emission strength and open site. (3) Appraisal Conclusion of Sound Environmental Impact In the construction, the noises of construction machine are main source. Sanbaigan reclaimed water supply works will cause impact on the surrounding environments of Shanba Husbandry Union and Sanbaigan Wastewater Disposal Plant nearby; Qibaigan reclaimed water supply works has impact on Wuyuan Brick Plant and other enterprises; the wastewater treatment and recycling works of processing park of Wuleteqian Banner has impact upon sound environments of adjacent Shagedan Village; sea area works of Wuliangsuhai Lake has some impact on sound environment of the sea area; and other planned works have less environment sensitive points around and the impact of construction noises is little. Do lower the artificial noises, take proper sound insulation measures and set up construction enclosure, and reasonably arrange the running time of high-noise equipment and avoid operation at night for reducing environmental impact in the construction of the project. Moreover, select proper positions for equipments, leverage national conditions for reducing noises so as to minimize the noises impact in construction period. (4) Appraisal Conclusion of Environmental Impact of Solid Domestic and construction garbage should be timely transported to a site designated by environment and sanitation authorities for disposal, in order to avoid environmental impact around. Try to use the waste soil of the works in the construction of various works of the project; contact local muck authorities for arranging disposal for the unused waste soil. If waste soil is piled up on the yard, ecologic greening should be immediately done after the construction over, and moreover, anti-flood ditch is required for preventing land erosion. The construction area of the sea area grid excavation works of Wuliangsuhai Lake is 2.451×106m2, where about 2.295×105m3 substrate sludge is produced. With high water content, the excavated sludge may cause secondary pollution with no proper protective measures. The Environment Monitoring Station of Bayannaoer Municipality has monitored the heavy metal content of the substrate sludge of the sea area of Wuliangsuhai Lake. According to the result of monitoring, heavy metal content of substrate sludge on various monitoring points all aren’t higher than the standard in Control Criteria on Pollutants in Agricultural Sludge (GB4284-84) of the State. Therefore, the substrate sludge excavated in sea area grid works of Wuliangsuhai Lake can be used as fertilizer, and upper layer of substrate sludge is used in improving alkaline saline soil; and lower layer is the parent soil with no pollution, about 2.17 million m3, and can be used in piling up artificial island in the lake area, instead of shipment. (5) Appraisal Conclusion of Ecologic Environmental Impact The impact of project construction upon ecologic environment is mainly the damage of soil and natural vegetation caused in the construction of various works and laying of pipelines. The construction of the reclaimed water disposal facility, wastewater disposal & recycling facility and artificial wetland of Wuliangsuhai Lake with permanent land occupation is done mainly on wasteland and partly on farmland, and will reduce the land of farmers to some extent; present reed land is manly used in artificial wetland construction of Wuliangsuhai Lake, instead of any nature change of present land, and ecologic impact of permanent land occupation is little. The construction of project pipelines features temporary land occupation, and produces partial and temporary impact and is restorable after the construction is over. The unfavorable impact upon landscape in the construction period of the project is short-term and restorable. The construction segments of the project with probable land erosion are mainly ground excavation in pipeline laying, and the construction of reclaimed water facility, wastewater disposal and recycling facility and artificial wetland of Wuliangsuhai Lake as well as earthwork excavation. The land erosion impact of pipelines construction on the construction stage strictly in conformity with the water and land conservation proposal and managing measures defined by various works is under control. Floating substance of sea area grid waterway works of Wuliangsuhai Lake in the construction will shape a high-density floating substance distribution zone in some scope around the construction site, which may consequently cause a decline of aquatic plankton, zooplankton variety and quantity. However, such impact is reversible. With the completion of the engineering construction, such impact will disappear soon. Floating substance of stability pond and deposition pond of artificial wetland works of Wuliangsuhai Lake in construction will shape a high-density floating substance distribution zone in some scope around the construction site, which may consequently cause a decline of aquatic plankton, zooplankton variety and quantity. However, such impact is reversible. With the completion of the engineering construction, such impact will disappear soon.

(6) Appraisal Conclusion of Social Environmental Impact The impact upon traffic in construction period has three aspects: � road is broken in pipeline construction and the traffic is hindered; �earthwork pile-up and road excavation hinder the traffic; and, � transport vehicles will increase the vehicle flow on the road. For ensuring construction safety, overall medical examination is required for all construction persons on the site, and any person with infectious diseases should be prohibited on the construction site; regular medical examination is required for the working staff of mess, and any person with epidemic disease should be timely treated and transferred out of the mess immediately for preventing the prevalence of the disease. The construction site should be provided with centralized water supply facility. Water source should be sterilized and monitored. Medical service facilities should be available on construction site. Proper labor protection should be provided for construction personnel for their health and safety and smooth implementation of the project. 12.4.2 Environmental Impact in Operation Period 12.4.2.1 Air Environmental Impact In the operation period of the planned reclaimed water supply works, the sludge disposal area will emit some stench, and the sterilizing device may emit chlorine dioxide and chlorine gas in abnormal working status. Chlorine adding room is equipped with alkaline solution spraying facility. Therefore, no obvious impact will occur on atmospheric environment. The site of wastewater treatment and recycling works of the project is within relevant processing park. Analogy analysis reveals that stench substance will have no impact upon surrounding villages. A preset 150m sanitation protection distance is reasonable. Moreover, the most adjacent sensitive target is 200m away from the boundary of wastewater treatment & recycling works of processing park of Wulateqianqi County. The impact of stench pollutant is slight. The waste gas of the artificial wetland works of the sea area the project of Wuliangsuhai Lake mainly includes CO2 in microbe decomposition as well as the stench from rotten plant & animal and living microbes, is little and has emission concentration in conformity with the Grade-II standard of the allowed highest concentration of plants in Emission Standards on Pollutants of Urban Wastewater Disposal Plant (GB18918-2002). 12.4.2.2 Water Environmental Impact Wastewater treatment and recycling works of the project produces reclaimed water for industrial enterprises in processing park with no wastewater, is able to save 22.63 million m3/a water resources, reduce a pollutant emission of the valley i.e. CODcr by 10950.0t/a, BODcr by 6022.5t/a and ammonia nitrogen by 730.0t/a at designed wastewater scale and plays significant role in cutting off total water pollutants of the region after put into operation. The planned reclaimed water supply works can reasonably dispatch water resources, boost utilization efficiency of water resources, reduce exploitation of underground water resources by 51.024 million m3, protect underground water resources, alleviate the continuously declining status of underground water, and prevent the expansion of funnel area. Moreover, it can cut off the emission in the valley i.e. CODcr by 2847.0t/a, BOD by 1335.9 t/a & ammonia nitrogen by 491.29t/a, and improve water environment of the region. Backwash water of filtration sink, sludge water of deposition sink, waste water in sludge pressure filtration produced in the operation of various works of the project are recycled. The ultra-filtration and hyper-filtration tail water in Sanbaigan reclaimed water supply works, Qibaigan reclaimed water supply works and reclaimed water supply works of Ganqimaodu Port Processing Park all is sent to the front water distribution terminal after deposition treatment for recycling treatment with the raw water of reclaimed water. Waste water isn’t discharged. Different disposal measures and modes are applied for the domestic wastewater of reclaimed water supply works according to the infrastructure around the works. The wastewater of reclaimed water supply works of processing park of Wulatehouqi County is sent to the wastewater disposal works of the processing park of Wulatehouqi County for treatment; domestic wastewater of Sanbaigan reclaimed water supply works is sent to Sanbaigan wastewater disposal plant to the north of the works for treatment; domestic wastewater of Qibaigan reclaimed water supply works is sent to Qibaigan wastewater disposal plant to the north of the works for treatment; and the domestic wastewater of reclaimed water supply works of Ganqimaodu Port Processing Park is treated in underground biochemical treatment equipment in conformity with Urban Wastewater Recycling—Quality of Urban Water for Different Purposes (GB/T18920-2002), and used for different purposes in the plant, instead of any emission. After completed, ecologic-transitional-belt artificial wetland of Wuliangsuhai Lake of the project can cut off the pollutants discharged into the lake: CODcr by 9781.19 t/a, NH3-N by 1990.57t/a & 299.24t/a. The model predicts that in non-frozen period, outlet water quality could reach Cat-IV standard (average) of the State’s Quality Criteria on

Surface Water Environment GB3838-2002. That is to reduce pollutant concentration of water: CODCr 30mg/l, TP 1.5mg/l and TP 0.1mg/l. In sum, after the project is completed, the total reduction of pollution loads of Wuliangsuhai Lake is: COD by 23578.19t/a, TP by 458.38t/a. Therefore, the project has no negative impact upon the surface water environment. With the implementation of the project, the trend of serious pollution of Wuliangsuhai Lake will be preliminarily controlled. The quality of water returning from Wuliangsuhai Lake into the Yellow River will be largely improved. 12.4.2.3 Sound Environmental Impact The predicted plant noise values of reclaimed water supply works and wastewater treatment and recycling works all comply with Grade-II standards in Criteria on Plant Noises of Industrial Enterprises (GB12348-90). The results of overlapping with present noises prove that with no densely populated point around the plant site, the impact of various noises upon prediction points aren’t exceeding the standard at daytime and night after the project is completed. As a result, in operation period, the equipment noises of reclaimed water supply works and wastewater treatment and recycling works have little impact upon the surrounding environmental. Water pumps of sea-area artificial wetland of Wuliangsuhai Lake in operation period produce high noises value and strong strike, and some may last for long time with violent shock. With the construction area 5-10km away from natural protection zone, the impact will occur for the birds in the region in nidification, food seek, wooing and hatching under national protection. 12.4.2.4 Solid Waste Impact (1) The solid wastes of the reclaimed water supply works in operation may include domestic garbage and dehydrated sludge. The output of solid waste of various reclaimed water supply works is included in Table 3.3-5. The plant area is set up with garbage station, where domestic garbage and dehydrated sludge will be piled up together, and regularly cleaned & transported to local garbage plant for burial treatment. Therefore, it has no impact upon the environment. (2) The solid waste of wastewater treatment & recycling works of processing park after put into production mainly includes domestic garbage, bar residue, deposited sand and biochemical sludge. The output of solid waste of wastewater treatment and recycling works of processing park is included in 3.3-12.

� The plant area is set up with garbage station, where domestic garbage will be piled up together, and regularly cleaned & transported to local garbage plant for burial treatment. Therefore, it has no impact upon the environment. � The bar residue, deposited sand and biochemical sludge of wastewater treatment and recycling works of processing park will be treated as different categories. Set up bar residue and deposited sand drying yard for lowering the water content; set up a sludge-piling shed for temporary storage of sludge with canopy on top. The ground of piling shed must be completely hardened, and cofferdam, drainage ditch and collecting well should be set around piling shed. The drainage in sludge piling process should be sent back to the wastewater disposal system for circulation and treatment. The impact of sludge piling upon shallow underground water around the plant site should be prevented. Sludge is regularly transported to Baotou Dangerous Waste Disposal Center of Inner Mongolia (in the middle and west of Inner Mongolia) for burial treatment.

Closed tank is used for sludge transport in order to avoid public hazard in the transport. 12.5 Relief Measures of Environmental Impact The environmental protection measures of the project involve two stages i.e. construction period and operation period, including the relief measures of water environmental impact, ecologic environment, atmospheric environmental impact and noises pollution as well as water & soil conservation measures. Generally speaking, the relief measures of environmental impact of the project are feasible by and large. If relief measure of environmental pollution of the project is well-prepared, pollutant emission can comply with the standard. The investment of the project for the environment protection is RMB63.8675 million, accounting for 6.41% of the total investment of the project. 12.6 Conclusion of Analysis on Environmental Benefits The project through the construction of reclaimed water supply works and wastewater treatment and recycling works of processing park and implementation of integrated sea-area improvement works of Wuliangsuhai Lake can dispatch the water resources comprehensively, improve utilization rate of water resources, adjust a water demand conflict between
