I. INTRODUCTION

1. The Secondary Green Cities Development Program (Green Cities) will demonstrate economically competitive, environmentally sustainable and socially inclusive development for Vinh Yen city (Vinh Yen), Hue city (Hue) and Ha Giang city (Ha Giang) of Viet Nam. The project cities' green and climate resilient development approaches will be scaled up for nationwide green secondary city development in Viet Nam.

2. According to the Safeguards Policy Statement (SPS) of 2009 of the Asian Development Bank (ADB) and an understanding of the impacts that will accrue from the subproject implementation, the Project is classified as Category B because the potential adverse environmental impacts are site-specific, few if any of them are irreversible, and mitigation measures can be designed readily. An initial environmental examination (IEE) was disclosed on ADB’s website for entire Project including three EMPs for the subproject cities: Ha Giang, Hue and Vinh Yen in August 2018. The IEE concluded that the potential direct environmental impacts are mostly construction related and thus short-term and acute and can be prevented or mitigated with standard construction methodologies and procedures and operational safety measures.

3. During the preparation of that IEE, three stand-alone EMPs were prepared for three subproject cities. In the context of the project, the preparation of the original IEE and EMPs was parallel with the development of the project Feasibility Study (FS). At the period of detailed design, there are possibilities of change between FS and final detailed design leading to a requirement of updating original EMPs to ensure the subproject in line with the ADB Safeguards Policy Statement (2009) as well as to reflect the final detailed design including supplement assessments, measures for arising environmental issues from the detailed design.

4. The Vinh Yen subproject consists of seven (07) components with 9 construction packages.

5. This updated EMP is prepared for the component “Strengthening existing drainage and wastewater system in four wards: Dong Da, Ngo Quyen, Khai Quang and Lien Bao”, CW packages 05 because of its detail design was approved in May, 2021. The previous EMP, which was applied to CW Package 02, 03 and 04, was approved by ADB in October, 2020. The EMP in 2020 is prepared for 04 CW packages 02,03,04 & 05. However, due to the delay of detailed design of VY-CW05 in 2020 and the urgent need of uEMP incorporation in the bidding documents for VY-CW 02, 03 & 04, the uEMP in 2020 was focused on the three CW packages (CW02, 03,04) which its detailed design has already been completed.

6. There was no significant change made during the design phase reckoned from the feasibility study phase of the component: Strengthening existing drainage and wastewater system in four wards of Dong Da, Ngo Quyen, Khai Quang and Lien Bao, hence, the identified potential impacts and assessment undertaken during the preparation of the IEE disclosed in 2016 and the EMP in 2020 are still valid and appropriate to the package under the component.

7. The updated EMP (uEMP) besides reflecting the changes by the detailed design, also summarizes potential environmental impacts of the subproject from the IEE and EMP 2020, and updated mitigation measures and monitoring requirements for the pre-construction, construction, and operational stages of the subproject. The uEMP seeks for environmental protection during preconstruction, construction, and operation continuously to prevent, reduce, or mitigate adverse environmental impacts and risks.

8. The uEMP includes an environmental monitoring program. The results of monitoring will be used to evaluate: (i) the extent and severity of actual environmental impacts against predicted impacts; (ii) the performance of environmental protection measures and compliance with relevant Vietnamese laws and regulations as well as compliance with internationally accepted standards as defined in the IFC Environment, Health and Safety Guidelines; (iii) trends of impacts; and (iv) overall effectiveness of the uEMP.

9. The bidding documents for construction contracts will be derived from standard ADB documents for national competitive bidding, and will include contract clauses requiring the contractor to implement the relevant clauses of the uEMP. These standard Contractor Specifications will be included in the Bidding Documents for works contracts.

1.3. Electricity, Water and Fuel for Construction

20. Demand for electricity is mainly for execution of hand tool equipment and lighting, operation of construction management offices and worker’s camp, obtained from the existing local 0.4 kV power grid or from the diesel generator of the construction units. The demand for electricity during construction period is estimated to be 20 kWh per day.

21. Water is mainly used for water pouring for dust reduction, water used office and worker’s camp. Clean water can be bought from local resident or transported from licensed source. In case of collecting water from existing canal/river surrounding project area, contractors have responsibility to get permission from local authorities. The estimated clean water usage for individuals during construction period is 150 liters/person/day, equivalent to 6.0m3 per day for 40

24. The materials for construction of the physical works including sand, cement, stone, steel ... are available in Vinh Phuc Province. All material sources have been granted with the exploitation license issued by the Provincial People’s Committee with plentiful reserves which can serve the need for materials by many projects throughout the city and in line with the decision No 2065/QD-UBND issued on Aug 15 2011 on “the master plan of construction material development on Vinh Phuc Province up to 2020 with a vision to 2030”1. The workers are equipped with equipment and labor protection tools. They are entitled to training sessions on labor safety. Based on construction material survey prepared by detailed design consultant, there are licensed quarries, mines potentially used for the construction as follows:

- Minh Quang stone quarry located in Minh Quang commune - Tam Dao district - Vinh Phuc province, has been exploited for many years with capacity of 3,000,000m3 under management of Minh Quang Construction Material Company. The distance from the quarry to the site of the WTP is 14km along DT302.

- Bao Quan stone quarry located in Minh Quang commune - Tam Dao district - Vinh Phuc province, has been exploited for construction since 2017 with capacity of 2,000,000 m3 under management of Bao Quan Construction Company. The distance from the quarry to the site of the WTP is 14km along DT302.

- Sand is bought from Song Lo sand mining Company in Viet Xuan commune - Vinh Tuong district - Vinh Phuc province. The distance to the site of WTP is 15km.

- Cement is purchased from domestic cement factories such as Hoang Thach, Nghi Son in Vinh Yen City, 2-3 km to the site.

25. The borrow pits for stone, soil and sand used for the works will be identified by the contractor(s) among the licensed existing pits, after the contract(s) is concluded between PMU and the contractors (bid winner(s)). Before signing supplying contract with material suppliers, the Contractor will be responsible for checking the validity of licenses, adequacy of environmental certificates required by national regulations; and (ii) consulting with communities adjacent to the quarry, mine, any quarry, mine with complaints of environmental pollution will not be used for the Project.

III. POTENTIAL ENVIRONMENTAL IMPACTS

28. There were no significant changes compared to proposals in FS study of the component that may arise unanticipated adverse impacts or cause negative effects on protected areas or natural conservation. hence, the identified potential impacts and assessment undertaken during the preparation of the IEE disclosed in 2018 are still valid and appropriate to the CW5 package under the component.

29. Compared to the impact assessment conducted in the original IEE report, the risk from COVID19 pandemic during construction have been added during updating EMP. In addition, this chapter will identify and evaluate the impacts in more detail and comprehensively, and propose more specific mitigation measures thanks to public consultations conducted during updating EMP, the completed detailed design, field survey, detailed information on the location of the disposal sites and sources of construction materials

30. The potential impacts of the construction and operation of the components from the IEE that are assessed in Table 10 are caused primarily from the civil works during the construction phase of the subproject. The short-term construction disturbances concern noise, dust, soil erosion & surface water sedimentation, reduced access, increased traffic and risk of traffic accidents, worker and public safety, and construction solid and liquid waste. These short-term impacts can be managed and mitigated with measures defined in the Mitigation Plan provided below.

31. Mitigation measures that will permanently become part of the infrastructure such as landscape planting and re-vegetation, road restoration, and markings are included in the main civil work contract costs. Temporary mitigation measures during the construction stage (e.g., dust suppression by watering, use of quiet / well maintained mechanical equipment, provision of soil erosion berms to prevent surface water sedimentation, provision of sanitary facilities for construction workers, etc.) will be incorporated into bidding documents and contract to ensure that contractors include them in their budgets.

Table 10: Summary of potential impacts of Vinh Yen subproject component types

No Impact Impact Level Description of Impact

Pre-construction phase

1 Land acquisition and resettlement

Low

According to the updated resettlement plan report for the Component 2 and 3, the area required for land acquisition of CW05 is 3.3m2 from Lien Bao ward of Vinh Yen city This area is paddy land of one household.

Land acquisition and resettlement impacts from the components do not cause any significant environmental consequences due to the small affected area is and this area is in the agricultural area.

2 UXO High

If the unexploded ordnances (UXO) are not cleared, this can be a risk in construction phase which can directly affect workers, local people and surrounding infrastructure. This impact is rated as HIGH and has a long-term impact on the psychology, health, property and lives of workers and people in the vicinity of the incident. At the same time, these impacts can affect a wide range, affecting the air, causing deterioration of soil quality. However, this impact can be mitigated through clearance of bombs, mines and unexploded ordnances by functional units.

The clearance of UXO is an important work to avoid possible threats to surrounding structures and to the safety of citizens and construction workers. For this project, this clearance work should be carefully conducted before commencement of construction. The impact of UXO has a significant negative impact without mitigation measures, with high risks to health, life and infrastructure. UXO clearance must be completed prior to commencement of construction works and the construction activities are only conducted within the UXO-free areas.

Construction phase

3

Air pollution causing by dust and air emissions from the excavation, ground leveling, transportation and operation of construction equipment

Medium

For construction of pumping stations, installation of the pipelines, the activities listed below may cause adverse impacts such as dust pollution and emission of exhaust gases: - Operation of equipment and vehicles emitting exhaust gases (NOx, CO, CO2, hydrocarbons, VOCs,

etc.) as result of the combustion of fuels, such as gasoline/petrol, diesel fuel, fuel oil; - Transport of materials and excavated unsuitable materials of the installation of transmission main

would cause dust (PM10, PM2.5) by dropping materials/waste as well as exhaust gases; - Earthworks creating a dusty pollution by soil excavation activities; - Stockpile of dry soil, sand, cement as well as loading/unloading of fine aggregate, cement and sand - Dry exposed areas do not be watered as scheduler Acute increases in level of dust and exhaust fumes may cause respiratory or lung diseases (i.e.: sinusitis, asthma, etc.) for residents and workers that are directly exposed to these conditions for extended periods. Dust is a visible pollution causing mostly complaints from local people to construction activities, it also effects the business of restaurants along the pipe alignments. For CW05, the scope of excavation and total volume of construction materials (190,773 m3), the large number of 10T trucks (16 units) is quite large, same as large number of other construction vehicles and equipment during the construction time of 18 months, but the scale of each section/item is quite small, so the impact is also moderate, short-term and mitigative

17

Sensitive receptors: Project covers 04 wards of Vinh Yen City, in which covers some sensitive subjects as schools (Tran Quoc Tuan Road) and kindle garden (Le Chan Road), markets (Le Xoay Street) and hospitals (Phan Chu Trinh Road). Duration of impact: during 18 months of construction

4

Water pollution causing by construction and domestic wastewater and run-off water

Minor during the construction

As the construction activities of the works under component 3 will be land-based, no direct impacts on water bodies will arise during the construction. The water bodies affected indirectly by each section of the component are different without direct connection among them causing no cumulative impact on water quality from the works. The local water bodies might be affected adversely by surface run-off, domestic wastewater from workers, and construction wastewater during the construction.

✓ Construction wastewater:

Construction wastewater is generated mainly: (i) concrete mixing for construction of pumping stations (ii) washing materials and construction equipment (iii) Uncontrolled discharge of debris and rubbish such as packaging, construction materials and refuse etc; and (iv) Spillages of liquid stored on-site, such as oil, diesel and solvents etc.

Construction wastewater usually contains high content of pH (usually pH>12), high content of total suspended solids and no hazardous substances. If this construction wastewater is not treated, it will cause sedimentation, affecting the receiving water bodies. However, the effects on water quality from the construction activities are likely to be minimal, provided that site boundaries are well maintained and good construction practices are implemented to ensure that litter, fuel and solvents are stored and handled properly

✓ Sewage effluent produced by on-site workforce

Personal wastewater of the workers: Estimated maximum number of workers for the CW05 the biggest work under this component is about 40 people. Required water volume for each worker as mentioned clearly in QCXDVN 01:2008/BXD is 150 liters/person/day (for washing, cooking and drinking). Daily generated wastewater volume is taken as 100% of daily used water volume. So, total daily generated wastewater volume is about 6.0 m3/day by 40 workers. In domestic wastewater, there are suspended particles, oil/grease, high Concentration of organic substances, sediments, dissolved organic substances (such as BOD, COD), nutrients (N, P) and micro-organisms

✓ Construction site runoff and drainage

During the construction, runoff and drainage from the works areas would be the main sources of potential water quality impact. Site runoff and drainage may contain increased loads of suspended solids and contaminants. Potential sources of pollution from site drainage include: runoff and erosion from exposed soil surfaces, earth working areas and stockpiles; release of grouting and cement materials with rain wash; wash water from dust suppression sprays; and fuel and lubricants from maintenance of construction vehicles and mechanical equipment. Site runoff and drainage from the works area on the upper hillslope, if uncontrolled, could enter the drainage culvert.

The amount of wastewater generated at each site is small, the construction period is short (18 months), locations of pumping stations are far from local water bodies. Moreover, the frequency of wastewater

18

generated from concrete mixing takes place intermittently. Therefore, the impacts caused by construction wastewater are assessed as Minor and can be mitigated

Generation of solid and hazardous waste needing to be disposed

Medium

Solid waste generated in the construction phase of CW05 includes 3 main types as follows: (1) Construction solid waste (including demolition waste and excavated soil); (2) Domestic solid waste; (3) hazardous solid waste. The waste generated by construction activities creates negative environmental, economic, and social impacts. Beside causing dust as assessed above, the environmental impacts include soil and water contamination and deterioration of landscape. Also, construction waste has indirect impacts in term of health and safety of workers, local people. The generated volume of different types of waste is assessed as follows:

✓ Construction solid waste

Demolition of temporary structures will generate concrete rubble, plastics, metal, glass, asphalt from surfaces, wood and refuse. This material consists of an assortment of inert rubbish such as plastic and concrete, as well as rubble and mixed soils.

The waste volume by construction can be estimated between 1% and 10% of each material type delivered to the sites (Bossink and Brouwers2). Given that the estimated volume of waste by construction is presented in Table below:

The component Total volume of

construction material (Sand, soil, cement, steel, stone)

Unit Estimated volume

of waste by construction

CW05 197,773 (m3) 1,977 – 19,777

All construction wastes shall be sorted on site into inert and non-inert components. Non inert materials (wood, paper, vegetation...) shall be recycled or reused and disposed to landfill as a last resort. Inert materials (soil, rubble, sand, rock, brick and concrete) shall be separated and reused on site. Scrap metals shall be recovered from demolition waste and recycled.

✓ Domestic solid waste

Domestic solid waste are mainly packages, plastic bags, bottles, cans of food, etc. The volume is assessed by rapid assessment method of the World Health Organization, the volume of solid waste discharged every day is 0.5kg/person/day. The estimated volume of the total solid waste generated during the construction of CW05 is about 20kg/day in total. This is the main source of pollution due to the decomposition of organic matters that creates bad odor, leachate and pathogenic microorganisms. If this source is not collected reasonably, it will cause environmental pollution. However, the works under

19

this component are not close to each other but distributed within the different wards of the city.

✓ Hazardous waste

Sources of hazardous waste generated from the construction of the project’s items include: (i) Oil contaminated materials from the maintenance of construction machines; (ii) bags, tanks containing oil, asphalt, petrol and paint; (iii) excessive welding rods; (iv) Batteries, light bulbs, cartridges from office at the construction site. The volume of hazardous waste depends on the number of equipment/machineries, labor and volume of materials: If the maintenance of means, vehicles, construction machines is carried out at the construction site, it will generate oil, oil bottles and oil contaminated rags, etc. (estimated at 5kg/month). If not collected and treated, it will affect the landscape, polluting the surface and underground water in the project area. Therefore, counter measures should be implemented to collect and to treat the hazardous waste (as per instructed by Circular No. 36/2015/TT-BTNMT and Decree No. 38/2015/ND-CP on waste management) and to minimize negative impact on local environment. Besides, all equipment and construction must be repaired in the repairing center The volume of bags, tanks containing oil, fuel and paint are not large (about 10 - 15kg/month). However, unless being collected, it will cause a loss of beauty landscape and a potential risk of soil and water pollution. Wastes from welding rods which are used form steel frames are generated at the construction site. It is estimated that the percentage of excessive part of welding rods is equal to 5-7% of the weight of welding rods, about 5.0 kg. However, the weld rods are discontinuously and rarely used, the waste will be collected to the regulated hazardous waste site in compliance with regulations. Hazardous waste generated, with a small volume, from office activities with about 1-3kg/month for a construction site. Hazardous waste, if not collected, will cause impacts: - Penetration of oil and grease into the water will directly affects aquatic species in canals within the project area, that curb the growth, or even cause death of aquatic plants and animals. - The heavy metal elements will therefore penetrate into the food and badly affect people health. However, the volume of hazardous waste generated on each site is small, localized and only occurs during the construction phase. Hazardous waste will be collected, managed and disposed in accordance with the regulations on hazardous waste collection and management. This impact is assessed to be MEDIUM and can be mitigated through appropriate management.

6 Noise and Vibration pollution

Low ✓ Noise Pollution

During the construction phase of the project, noise generated mainly from the following sources: - Transportation of construction materials, solid waste;

20

- Construction and dismantling works items; - Operation of construction equipment at the construction site. The noise will mainly affect construction workers, people living nearby the project area and along the transportation route. High noise level will cause health effects such as insomnia, fatigue, uncomfortable mood. It can also affect workers’ performance on the construction site, making them less mentally focused and easily leading to occupational accidents. According to QCVN 26: 2010/BTNMT, the maximum permissible noise level is 70dBA in the production area and the lowest noise level is 45dBA in health centers, libraries, nursing homes, schools from 21h to 6am. For residential areas, the maximum permitted noise level must not exceed 70dBA. In addition to the source of dust and emission gases from earthworks and vehicles, the operation of construction machinery and equipment such as bulldozers, hoists, drilling machines, excavators, trucks ... also cause noise pollution and great vibration. Forecast on noise level generated by some main construction machines and equipment is shown in the table below.

No Name of

machine/equipment Noise (dBA) at a distance of

6 Pump 76

7 Concrete drill 82

8 Concrete mixers 85

9 Asphalt Spreaders 78

10 Cranes 83

11 Dump Truck 10 tons 84

(Source: Construction Noise Handbook, U.S. Department of Transportation, updated 24/08/2017) The noise level at a distance of 30m from the construction vehicles and equipment is within the permissible limits (<70dB). The noise is decreased by distance from the construction site. Among the above noise sources, the most noticeable is the noise of trucks transporting construction materials through residential areas. The noise level at the construction sites is LOW, generating in a short time and scattering over 4 wards under the component. Construction machinery and equipment will not work simultaneously but in shifts and phases depending on the progress and construction volume of items, of which each type of machine will be used differently, so the resonance impact is very low. Moreover, all vehicles and equipment will be checked periodically and noise will cease when construction is completed. Noise can be minimized

21

by measures such as labor protection equipment and noise protection devices.

✓ Vibration pollution

Vibration can be generated mainly from equipment operating with large capacity and often on sites such as bulldozers, excavators, air compressors, etc. from activities of leveling, road pavement…when recovery of roads excavated to lay pipelines. Vibration can directly affect the workers involved in operating the machines, the people living nearby and the infrastructure around the construction site. Vibration will affect people's daily life, business activities and other structures and even cause the cracks or collapses of houses. When the intensity is high and the effect is long, it can cause discomfort to the body. Vibration combined with noise makes the hearing organ too tired, affecting human health.

Similar to noise pollution, vibration impact is Low as a few numbers of equipment, machine mobilized during construction.

7 Social impacts from construction (Disturbances to the local communities because of the concentration of workers at the site, or impacts on local infrastructures because of material transportation) and Risks of community and worker safety

Low Social impacts are mainly generated from the labor influx for construction activities. There will be 4 camps and some construction in four wards Ngo Quyen, Dong Da, Lien Bao and Khai Quang. This impact affects people around the work area and local infrastructure. Social impacts include but not limited to: - Conflicts between construction workers and local communities due to differences in habits,

customs, culture, lifestyle, employment and income. This impact is likely to be higher in densely populated construction areas such as the urban roads where proposed pipelines are located in four wards (Ngo Quyen, Dong Da, Lien Bao and Khai Quang)

- Conflicts between local residents and the Contractors when wastes generated from construction activities such as dust, solid wastes, hazardous wastes, wasted rock and soil cause adverse impacts on crops, rice and vegetables, or erosion and landslides to agricultural field

- Wastewater from worker camps discharged into the environment may also lead to conflicts with the local community. Besides, the conflicts can arise from workers’ use of local resources such as clean water, food and foodstuffs that cause price increase.

- Labor influx can cause social disorders and pose social problems such as gambling, drug, prostitution. Additionally, uncollected and untreated wastewater, which cause adverse impacts such as bad smell, loss of beautiful land scape and poor health of local people, from worker camps in or near residential areas (residential areas in three wards, wastewater treatment plant) can bring workers into conflict with local people.

- Use of local labor for simple jobs will pose the potentially risk of children involvement, affecting children’s psychology, health and development, causing conflicts with local residents.

- Impacts on existing infrastructure and related services:

22

+ Transportation of construction materials and wastes (using 10-ton vehicles) be risky of damaging local roads

+ Operation of excavators, drills, can break existing power lines along national highways in sections passing urban or residential areas within four wards

- Disturbance in traffics and increase in traffic safety risks: Construction vehicles and machines used in the project will increase the traffic density on the urban roads where pipelines are located, contributing to disturbance and increase the risk of traffic accidents and traffic jams.

However, the social impact is assessed to be “LOW” as: (i) the workers concentrated scattered in 4 different areas. The impacts are localized within the construction areas; (ii) Local labor will prioritized to use for construction activities. At the same time measures to control the age of hired workers must be taken; (iii) The impacts are mainly occurred in the early stages of construction phase and within a short period; (iv) the traffic density and frequency in the project area are low. Therefore, social impacts can be controlled by mitigation measures taken in the project construction phase.

8 Health risks related to COVID 19 pandemic

High Delivering civil works requires the assembly of a workforce, together with suppliers and supporting functions and services, and may lead to congregations of large numbers of people. The components require migrant workers to live in campsites or lodge within communities close to construction sites, local workers come to the sites and contact with other workers then return to their homes after works. These activities cause a high risk of getting and spreading COVID 19 virus. There may be also the regular coming and going of support services, such as catering, cleaning services, equipment, material and supply deliveries, and the interaction with sub-contractors bought in to deliver elements of the works. The potential for the spread of infectious disease during construction is high. In addition, the construction of the component may experience a number of the workforce becoming ill and will need to consider how they will receive treatment, and whether this will impact on local healthcare services.

9 Impact on local facilities

Low The project will have excavating and installing activities for the pipeline system with a total length of 13342m, the construction process may cause damage and interruption of public services such as electricity lines, domestic water lines, telecommunications cables, drainage systems. These impacts affect directly to the living and working activities of people in the project area.

However, because underground electrical wiring and telecommunications cables are not common, the existing water supply system and a new collection pipeline system have been planned and designed

23

with regard to the conflicting intersections between infrastructure systems. This impact is assessed to be LOW and can be mitigated through appropriate management.

Operation phase

10 Operations- & Maintenance- related issues (deterioration of the pipelines, broken parts, machine…)

Low During operation of the Component, deterioration of the pipelines is unavoidable. Problems related to “wear and tear” of the mains, such as broken pipe, valves, meters, pumps and others, may occur. If a pipe is broken the water cannot flow freely and it may collapse. The most common causes of broken pipes are poor installation, age and tree roots. If these system maintenance problems are not detected at an early stage, bigger problems may arise and disrupt the water drainage process and cause flooding to local areas. The impacts however are avoidable with much vigilance of the managing unit responsible for the operations and maintenance of the pumping stations and pipeline system. The pipelines are also located on stable geologic area with no history of serious earthquakes, the risk of pipes broken by natural hazards is very low. In view of this, the impact is considered as minor.

Specific impacts of CW05

11 Impacts on business activities

Low Laying pipeline on road surface will cause difficulties to access shops, restaurant located along the roads. If these problems occur for long time, the affected shops, restaurant will lose customers that may lead to the close of business. This impact is only from the installation of pipelines of CW05 and is minor because the pipeline laying method is section by section, completing one section then starting another.

12 Traffic and labor accidents caused by construction on roads

Medium during the construction

(i) Risk on health and safety of Workers at construction site Due to some component items working on roads, workers shall pose a risk of accidences by transportation means (cars, trucks, motorbikes, etc.). Such accidences include:

- Vehicles run too fast that the drivers cannot control properly, likely resulting in hitting workers;

- Workers carry out work activities with their back to ongoing traffic on the roadways;

- Workers work at bends on roadways and cannot be seen by drivers due to objects (houses, walls, etc.) obstructing the vision of the drivers;

- Workers carry out work activities and ignore coming vehicles, thus even being hit by vehicles;

(ii) Risk on health and safety for local communities: Effects of construction works on roads are to reduce available road width to road users, and the degree of reduction depends on the extent of the works involved, such as laying pipe, culvert works and surfacing roads, and so on. All of these road-related activities make local communities be at risk of health and safety. Such risks are as follows:

- Traffic accidences due to degradation of road surface quality that includes of road roughness (holes

24

and broken surface produced by construction and transportation activities) and slipperiness (dropping material such as sand, gravel, soil, etc.);

- Safety of local pedestrians, vehicle drivers caused by materials transportation. This impact is related to worker and community’s health and safety so it is moderate, however this impact is temporary and mitigable through practical measures

32. The EMP provisions will be incorporated into bidding documents, and where appropriate, into construction contracts, and operational management plans to be implemented by contractors under supervision of the PMU and SMC. The effectiveness of these measures will be evaluated based on the results of the environmental effect monitoring conducted by the PMU and SMC.

33. Each contractor will be required to prepare a site-specific Construction Environmental Management Plan (CEMP) prior to commencement of any site works. The CEMP shall specify the responsibilities, location, associated costs, schedule/timeframe and other relevant information for implementing mitigation measures during construction as indicated in Table 11 below

34. The CEMPs should be fully consistent with this uEMP. Before civil works begin, the CEMPs shall be reviewed and endorsed by the PMU and SMC, and shared with ADB (if required).

IV. MITIGATION MEASURE PLAN

35. The mitigation measures are presented in a comprehensive mitigation measure plan for the component in Table 11, 12, 13. The mitigation plan is structured by the three development phases of the subproject defined by the pre-construction; construction; and post construction operational phase. The mitigation plan addresses the environmental issues and concerns raised at the stakeholder meetings.

36. The mitigation plan combines construction phase impacts common to the CW package under the component for which single mitigation measures are prescribed. In this way common mitigation measures are not re-stated numerous times. However, impacts and required mitigations that are specific to a component type, or to one of the 7 individual components are also identified. Or, common mitigations that are particularly important to a subproject component are highlighted.

37. The mitigation plan identifies potential impacts, required mitigations, responsible parties, location, timing, and indicative costs.

V. ENVIRONMENTAL MONITORING PLAN

38. An environmental monitoring plan has been prepared for the component in accordance with the Government of Viet Nam and ADB requirements. The plan focuses on environmental compliance monitoring and environmental effects monitoring (e.g., air, water, noise, and dust) during pre-construction, construction and operation.

39. The monitoring plan consists of environmental compliance monitoring to be conducted by the PMU with support of the SMC, and environmental effects monitoring to be conducted by the SMC and potentially sub-contracted to a licensed monitoring entity. Contractors will also be required to conduct frequent noise, air quality and surface water quality monitoring around construction sites, and records of all worker accidents at all sites. Monitoring arrangements defined for this project are described below.

V.1 Environmental monitoring

40. Table 12 shows the environmental effect monitoring program for the subproject, defining the requirements, including, scope, location, parameter, duration and frequency of monitoring during pre-construction, construction and operational stages. The locations of monitoring sites which were adapted to Vietnamese EIA and shall be decided based on the situation of site condition. Environmental effect monitoring will include monitoring of air quality, noise, and water quality and will be conducted in compliance with relevant Vietnamese standards and procedures, including but not necessarily limited to:

- Circular No. 28/2011/TT-BTNMT: Regulation of technical procedures of environmental monitoring for ambient air and noise.

- Circular No. 29/2011/TT-BTNMT: Regulation of technical procedures of environmental monitoring for surface water.

41. Quarterly environmental monitoring of air quality, noise and water quality during pre-construction, construction and operation will be conducted by the SMC. The costs for environmental effect monitoring by the SMC have been estimated and included at package VY-CS01.

42. The environmental monitoring results will be compared to relevant Vietnamese performance standards and the IFC Environment, Health and Safety Guidelines where these are applicable. Non-compliance with these standards will be highlighted in the monitoring reports. Monitoring results will be submitted by the SMC through the PMU to Vinh Phuc DONRE, and to EA and ADB through the semi-annual environmental monitoring reports.

43. During construction, compliance monitoring will be conducted as the works are implemented by the SMC (Table 12). The compliance monitoring results will be documented in the semi-annual environmental monitoring reports. Compliance monitoring will be done on a monthly basis. Monthly reports will be submitted by the SMC to the PMU and EA. These reports will be consolidated in the semi-annual environmental monitoring reports to be submitted to the ADB, and DONRE by the EA.

44. The compliance framework, based on the environmental requirements established by the EMP that will be incorporated into bidding documents and contract arrangements, will be strictly enforced by the SMC. Minor and major infringements will be determined according to two primary infringement categories (Table 14).

Table 14: Category of Infringement & Remediation

Category of Infringement

Definition Remediation

Minor Infringement Incident which causes temporary but reversible damage to the environment, community property, people.

– Minor clean-up operations – Minor restoration activities – Adjustments to construction practices – Compliance with EMP and CEMP

Major Infringement Incident where there is long-term or irreversible damage to the environment, community property, and people

– Major clean-up operations – Comprehensive investigation of incident,

including reporting – Major restoration requiring engineering

measures – Major restoration of community property – Compensation to affected communities or

persons.

45. For a minor infringement, which is an incident causing temporary but reversible damage, the contractor will be given a reasonable period of time to remediate the problem and to restore the environment or strengthen safety procedures. If restoration is done satisfactorily during this period, no further actions will be taken. If it is not done during this period, the PMU will immediately arrange for another contractor to do the restoration, and deduct the cost from the offending contractor’s next payment.

46. For a major infringement, which is an incident causing long-term or irreversible damage or negligence to construction safety resulting severe injury or death of workers or community members, there will be a thorough internal and independent investigation of the incident by authorities such as Vinh Phuc DONRE or DOLISA. Financial penalties may apply in addition to the cost for restoration activities.

47. The compliance framework will be applied as follows:

– The SMC will identify or be notified of an infringement (community member, local government);

– The SMC in consultation with relevant stakeholders (PMU, DONRE, DOLISA) will assess whether it is a minor or major infringement.

48. For minor infringements:

– The SMC will establish the required mitigation measures, and issue a notice to correct, defining time period, which is a maximum of five days to remedy the situation.

– The Contractor will review the recommendation and confirm (i) the level of infringement (minor/major); (ii) the mitigation measures; and (iii) the mitigation time period. If they do not agree, they will work with the SMC and the PMU to reach mutually acceptable recommendations.

– The Contractor shall remedy the infringement in accordance with the recommendations within the agreed time period.

– The SMC shall confirm the infringement is satisfactory remedied in the time period.

66

– If the infringement is not remedied satisfactorily in the time period the CSC shall inform the PMU. The PMU shall immediately arrange for a separate contractor to undertake the necessary works and the cost of this shall be deducted from the next payment to the offending contractor.

49. For major infringements:

– The Contractor and/or SMC shall immediately inform the PMU of the incident;

– The PMU shall immediately inform the appropriate provincial authorities if appropriate (DONRE, DOLISA);

– The PMU, in consultation with the SMC and other provincial authorities as appropriate, shall agree upon mitigation and clean-up measures to be undertaken immediately by the contractor or by specialists to be procured at the contractor’s expense. To minimize the environmental impacts the restoration activities should be completed within ten days.

– In case of serious accidents incurring severe injury or death of construction workers or community members, the PMU will ensure that an investigation is conducted in accordance with the relevant Vietnamese regulations (i.e., Law on Occupational Health and Safety No. 84/2015/QH13, and the procedures defined in Joint Circular No. 12/2012/TTLT-BLDTBXH-BYT guiding the statement, investigation, statistics and reports on occupational accidents).

– The EA and/or the PMU shall apply a financial penalty, not to exceed 1% of the contract cost, for each major infringement, in addition to any costs associated with the infringement not borne by the contractor.

50. Any conflicts between the Contractor and SMC shall be resolved by the PMU. ADB expects to receive the following information related to serious project-related infringements or incidents: (i) a written notice of the incident within 24 hours; (ii) the minutes of the investigation issued by relevant authorities (DOLISA or DONRE) within 30 days; and (iii) a full inventory of minor and major infringements and accidents, to be reported in the semi-annual environment monitoring report to ADB.

V.2 Reporting Plan

51. The following reports related to the implementation of the EMP will be prepared and submitted to relevant agencies. Frequencies and responsibilities are shown in Table 15.

52. Monthly progress reports by the contractors: Each contractor will submit monthly progress reports to the PMU. These reports will include reporting on EMP implementation performance.

53. Quarterly reports by the SMC: The SMC will submit quarterly environmental monitoring reports to the PMU. These reports shall also include EMP and CEMP implementation progress, grievances received, minor and major infringements, occupational accidents, and necessary corrective actions.

54. Semi-annual environmental monitoring reports by PMU: PMU will submit semi-annual environmental monitoring reports in English to ADB for clearance and disclosure. The reports will follow the template prescribed by ADB. Semi-annual reporting shall continue until the project completion report is issued.

V.3 Capacity building & Training

55. The capacity of PMU and contractor staff responsible for EMP implementation and supervision will be strengthened. All parties involved in implementing and supervising the EMP must have an understanding of the goals, methods, and practices of project environmental management. The project will address the lack of capacities and expertise in environmental management through (i) institutional capacity building, and (ii) training.

✓ Institutional strengthening

56. The capacities of EA and the PMU to coordinate environmental management will be strengthened through a set of measures:

i. The appointment of a full-time and qualified safeguard officer (SO) within the PMU in charge of EMP coordination, including GRM and coordination of environmental impact monitoring, training, reporting, etc.; and

ii. The contracting of environmental specialists (one international - IES, one national - NES)) under the safeguard monitoring consultant (SMC);

V.4 Consultation, Participation and Information Disclosure

58. This section describes the meaningful public consultation, and information disclosure process conducted during project preparation.

59. Given there was no changes of location nor significant adjustment of scope of works by detailed design, the results of public consultation conducted in 2017 for preparing IEE are still valid

60. Though Category B for environment, an indicative plan for the subproject for follow-on public involvement during construction has been developed (Table 17). The PMU, who will be supported by the SMC, has the main responsibility for public participation during project which begins with the initiation of the GRM.

62. Costs for EMP implementation have been estimated for the following items: (i) environmental effects monitoring by SMC; (ii) environmental training program; and (iii) public consultation (included in contract of SMC).

✓ EMP supervision, training, and public consultation by PMU, SMC and Monitoring Institute

63. The PMU will assign a full-time environment specialist to coordinate environmental aspects of the subproject using its own resources, and will conduct public consultation when needed. The SMC will conduct training on EMP implementation. The SMC contract will include the recruitment of environmental experts (national and international) to supervise construction activities including EMP implementation.

✓ EMP implementation costs by contractors

64. Following Vietnamese laws and regulations, Works contractors must ensure abiding with the following four "HSET" criteria: Health for Community (Health); Site Safety (Safety); Environmental Protection (Environment) and Transport Management (Transportation).

65. The costs for works contractors' adherence with the HSET criteria and this EMP, including (but not limited to) recruitment of environmental and safety staff, environmental protection, construction site safety, work camp management, mobile noise control facilities, air pollution control and dust suppression, waste collection and transport, temporary flood control and slope stabilization, landscaping, restoration of borrow areas, fire and explosion prevention, vibration control, etc. during the construction stage are not detailed here. These measures will need to be included in the tender documents to ensure that contractors can reflect these in their cost estimates and proposals.
