3. The status of reservoirs under the subproject “Dam rehabilitation and safety improvement

(WB8) Phu Yen province: Most of reservoirs are homogeneous earth dams which have been exploited

for a long time and have not been upgraded, resulting in deterioration, damage, and weakness in

preventing flood. Main items of the works are likely to cause unsafety. In addition, most of the works

were built between 1983 and 2004 basing on hydrological documents, natural conditions, design

standards which are no longer suitable for the situation of climate change, especially the current

complex climate change. Facing with the above mentioned situation, repairing, upgrading and

ensuring of safety for the works is very necessary

Head works will be repaired and upgraded; ensure safety for reservoirs in exploitation and operation;

ensure irrigation water supply for 4,509.05 ha of agriculture land.

Status of reservoirs is presented in details in Annex 2.2.1 of this report.

4. Description of the subproject. The construction items of the subproject are implemented in 8

reservoirs, with the aim of supporting the implementation of the Program to ensure safety of reservoirs

through repair, reinforcement, upgrading of priority dams, strengthening of management capacity and

safe operation of dams to protect people specifically residence and socio-economic infrastructure in

the downstream area.

Specific objectives:

a) To secure the safety of reservoirs and key works.



b) To improve the efficiency of irrigation works in service of intensive cultivation, increase

productivity and quality of products, develop specialized areas of high yielding and high

economic value, maximize potential of agricultural land in the region.

c) To reduce water loss, to ensure the water demand for people's life, the development of local

industries, and socio-economic development in the subproject area in particular and Phu Yen

province in general.

d) To create natural landscapes, improve the ecological environment, promote tourism

development in the region.

Construction items:

a) Repairing, upgrading soil dams, reinforcing dam crest, repairing upstream slope, downstream

slope, reworking slope drainage systems and treating dams;

b) Repair, replace water intake culverts depending on the extent of damage;

c) Reinforce and renew to improve drainage capacity of spillway, it is possible to expand flood

discharge spillways and overflow with surface discharge gates or self-fuse spillways;

d) Management road: Depending on the current status of each reservoir, construction of concrete

pavement structure conforms to rural road standards.;

e) Renovating reservoir managers house: grade IV houses have electricity and water systems for

daily life and reservoir management;

f) Monitoring equipment: To build a system of upstream and downstream water level

observation posts

5. Results of environmental and social screening: The subproject is not located in or near natural

habitats and there is no rare or endangered animals and plants found in the subproject area. There are

also no sensitive construction or monuments that have cultural, religious or historical significance in

and around the subproject. Regarding ethnic minorities, there are 4 communes under the subproject

that have ethnic minorities: Xuan Phuoc, Hoa Tan Tay, Ea Bar, Son Dinh, The ethnic minority groups

here are mainly Cham and Khmer. The subproject will only upgrade the dam on existing reservoirs,

which has been screened for the environment and society and determined that the subproject does not

cause significant impacts on the environment and society in the project implementation area and the

subproject is rated as category B in terms of environmental and social impacts. The World Bank

policies are triggered under the subproject including: OP/BP 4.01 on environmental assessment, OP

4.09 on pest management, OP/BP 4.37 on safety of dams, OP/BP 4.12 on involuntary resettlement;

OP/BP 4.10 Indigenous peoples, and OP/BP 4.11 Physical Cultural Resources.

6. The social and environmental impact assessment aims to identify both positive and negative

impacts of the subproject, thereby proposing appropriate mitigation measures to control and manage

those impacts, in order to optimize the benefits of the subproject.

7. Social and environmental impacts of the subproject: The subproject brings both positive and

negative impacts.

(a) Positive impacts:

- The subproject will repair and upgrade safety of head works of reservoirs to ensure safety

for people and their assets who live in the downstream area, and communes in subproject

and residents of neighboring affected areas;

- After being implemented, the subproject will improve the storing of reservoirs, improve

capacity of storing underground water in the nearby area;

- Regularly and sustainably provide irrigation water for agriculture cultivation area in the

downstream area;

- Improve landscape in the reservoir area and provide habitat aquatic life.

(b) Negative impacts during pre-construction and construction phases, including:

- The implementation of the subproject will recover the productive land of the households in

subproject area. The implementation of the sub-project will permanently acquired a total of



49,274.73 m2 belonged to 16 households and 5 organizations are People's Committees of

communes, in which: 2 crops Rice land: 771.29 m2, Other annual crops land: 1,533.66 m2,

Land for perennial crops: 172,35 m2, Production forest land: 19.121,96 m2, Residential land:

36,17 m2 and: 27,639.3 m2 Public land managed by the CPC includes 12.428,6 m2 Other

annual crops land and 15,146 m2 Unused hilly land and 64,7 m2 Unused land. In addition, the

project will temporarily acquired 14,500 m2 of unused land for landfill purpose.

- According to the results of consultations and interviews in the subproject localities, explosive

objects have not been detected in the subproject communes. However, Phu Yen province has

repeatedly discovered explosive objects and has been handled by the authorities. According to

a report on the status of landmine and UXO contamination (Vietnam National Mine Action

Center) Phu Yen province has 9/9 districts (cities and towns) identified as contaminated with

UXO as: Tuy Hoa city, Song Cau town and districts: Dong Xuan, Tuy An, Son Hoa, Song

Hinh, Tay Hoa, Phu Hoa and Dong Hoa; A total of 113/113 communes (wards and towns)

were identified as being contaminated with UXO, accounting for 100%, UXO contaminated

area is 107,950.22 hectares, accounted for 21.4% of the province's natural area. Therefore,

UXO can be found in the construction area or the land mine, stone. In order to minimize risks,

the subproject owner should contact the competent authorities to conduct mine clearance to

assess the risk and provide confirmation of the safety of explosive objects before construction.

- Site clearance activities, create construction ground, transporting waste due to clearance of

vegetation, soil stone will create impacts: Dust, exhaust gas, noise, vibration affect

construction workers, people in the subproject area; Wastewater from worker activities and

stormwater runoff with high suspended solids content due to loss of vegetation cover will

affect the quality of receiving water and soil quality in the subproject area; Solid waste of

workers and waste from clearing vegetation cover if not managed well will affect the

surrounding environment and landscape of the subproject area.

- Another activity in the subproject preparation phase is geological exploration drilling. In total,

the geological survey unit has drilled 17 boreholes with the depth of 11-40m at the subproject

locations (Specific positions are presented in the feasibility study report of the subproject) to

understand geological conditions and aquifer characteristics, at the same time conducting

geophysical karota in the borehole, If the drilling process is not handled properly, it will affect

the quality of groundwater sources due to the infiltration of pollutants through boreholes to

groundwater.

- The impacts related to construction activities such as noise, vibration, air pollution due to dust

and emissions, water pollution, waste, plant and animal ecosystems, social risk due to site

clearance and construction affecting traffic safety, community infrastructure, risk of accidents,

community conflict and infectious disease and disruption of business activities have been also

determined and assessed in the report. Moreover, during the construction process, it may be

blocked water source to construct the works of the subproject which may affect productivity

and water resource serving agriculture of 7 communes in the subproject area. The works of the

subproject are scattered in the 7 communes of 6 districts and the implementation location is

mainly on agriculture land which is far from residential and important areas and does not

affect forestry land; therefore, the negative impacts of the subproject are assessed at low to

average level and can be controlled by a suitable management plan. However, there are still

long term impacts on the subproject area such as land mine and dumping sites which can cause

degradation of agricultural land, unused hill land, and vacant land within the temporarily

borrowed land of localities in the subproject area during the process of using.

(c) Negative impacts during the operational stage:

- Dam safety risks can occur in the event of a broken dam or flood discharge causing flooding

downstream; Accident related to drowning;

- Domestic waste from eco-tourism activities in some reservoirs has developed this type of

service;

- The implementation of the subproject does not increase the capacity of the reservoir, does not

increase the irrigated area in the downstream area and does not affect the crop structure in the

subproject area. However, the repair of the culverts has been damaged and the leakage of



water will be overcome to ensure more stable irrigation water regulation and will provide

adequate irrigation water for the subproject area in the drought season, restore the volume and

initial irrigated area of the reservoir, At that time, the cultivation of agricultural crops for areas

that lack water in the drought season will be restored, on the other hand, when there is enough

irrigation water and water is frequently circulated, it leads to changes in living environment,

creating conditions for harmful organisms and plants to grow, This is also the cause of

outbreaks of diseases and pests for agriculture. Therefore, it will increase the number of

pesticides and fertilizers in the area of water shortage and increase the pest in the subproject

area. On the other hand, the use of chemicals to kill termites in the dam body if not well

managed also affects the surrounding environment if due to residue and disposal is not in the

right place or termite-killing chemicals are swept away by rainwater. Therefore, an integrated

pest management (IPM) plan for this subproject is required;

- During maintenance, repairs can stop provision of irrigation water temporarily affecting

production and livestock of downstream people..

8. Mitigation measures for impacts: To manage these impacts, an Environmental and Social

Management Plan (ESMP) has been prepared as an integral part of this ESIA report with proposed

institutional arrangements for impact management, environmental management and monitoring,

reporting requirements, capacity building, budgeting for implementation. The social assessment report

(SA) is made to aim at the following objectives: (i) Identify social issues and potential impacts of

proposed infrastructure investment items, (ii) Provide input of social aspects and participation in the

feasibility study project design and basic design phase, paying attention to the needs of affected

communities, (iii) Provide specific recommendations on infrastructure investment management with

high social risks and identify criteria and methodologies to determine whether the investment is

socially acceptable or not, (iv) The study provides a basic source of data for evaluating project

completion results. A separate Resettlement Action Plan/Compensation and Resettlement plan has

been prepared to deal with the impacts of land acquisition.

Preparation phase:

- Implement RAP; SA.

- Integrating environmental mitigation measures into technical design.

- Consult people about the actual time of repairing dam with purpose of mitigating impacts of

three phases: preparation, construction of subproject and operation of subproject.

- Demining and demining should be carried out strictly and fully in the subproject

implementation area. It is necessary to hire a unit with full functions and tasks of according to

state regulations.

- During the geological exploration drilling process, it is necessary to strictly follow exploration

drilling techniques. The boreholes need to be backfilled ensuring no spillage of pollutants to

the drilled hole and infiltrationinto the aquifer.

- Waste from the site clearance process has a small quantity but needs to be transported in the

right place or coordinate with the local authorities to handle the regulations..

- Putting provisions on implementing mitigation measures into construction bidding documents

and construction contracts.

Construction phase:

- Require contractors to strictly and fully implement mitigation measures for the impacts

mentioned in the Environmental and Social Impact Assessment Report, social impact

assessment report of the subproject and negative impacts during construction phase will be

minimized through ECOPs and mitigation measures for site-specific impacts.

Operation phase:

- During the operational process, the upgraded and repaired items of the subproject such as:

anti- seepage on dam body, treatment of loss of water due to damaged items will improve the

capacity of storing of water and ensure the capacity of regulating water through repairing of

intake. Thus, it will increase irrigation area that has been not provided enough for designed



irrigation area because of losing water of reservoirs. Therefore, introduction and promotion of

application of integrated pest management in the areas of irrigation services are necessary.

- PPMU frequently monitor to ensure that the damaged structures will be repaired and restored

in accordance with approved dossier. Reservoir management units regularly check dam safety,

patrol the Reservoir area to avoid drowning accidents; forecast and warning to authorities and

people when there are extreme weather phenomena; Regularly collect garbage at the reservoir

area, for reservoirs operating in tourism business, there must be garbage bins and coordinate

with garbage collection units in localities to collect daily. On the other hand, the PPMU and

the reservoir management and operation units must coordinate with the local authorities to

carry out the training on emergency response plans for local authorities and local people..

- For the impact of increased use of pesticides, agencies: Plant Protection Department of Phu

Yen province; Plant Protection Station of districts under the subproject; and the People's

Committee of 7 communes under the subproject must comply with the contents of the Pest

Management Plan (IPM) of this subproject. In addition, farmers in the process of cultivation

need to select good varieties, regularly check pests and diseases, use pest control measures

recommended in the pest management plan (IPM) such as: (i) Cultivation measures: Soil

preparation, field cleaning; rotation, intercropping; proper time; sowing and planting

reasonable density; use fertilizer properly; Appropriate care measures (ii) Use of breeds:

Traditional varieties and proposed varieties suitable for local conditions (iii) Biological

measures: taking advantage of using natural enemies available in the field, using bioproducts

…(iv) Chemical measures: use safe pesticides with natural enemies; follow economic

threshold ... Follow safety guidelines on pesticide storage, transportation and use to minimize

negative environmental and health impacts...

9. Preparation of a report on environmental and social impact assessment. The subproject is

designed and implemented in accordance with the DRSIP project's Environmental and Social

Management Framework (ESMF) approved by WB, and also ensure compliance with the current

environmental regulations of the GoV. The purpose of the Environmental and Social Impact

Assessment Report is to determine the importance of environmental and social issues in the decision-

making process by clearly assessing the environmental and social consequences of proposed research

before the implementation of subproject activities. Early identification and characterization of the

positive and negative environmental and social impacts that help the community and local have an

assessment of the subproject's environmental and social impacts propose conditions to be applied to

mitigate or mitigate risks to those impacts. Activities in the preparation, construction and operation of

the subproject are analyzed, evaluated and given solutions to prevent and minimize the level of

impacts on the environment and living of the residents direction. Results of screening of 8/8 reservoirs

all meet the criteria of the project and subproject is classified as category B in terms of environment

assessment. The subproject triggers 04 safeguards policies, including: OP/BP 4.01 on environmental

assessment, OP 4.09 on pest management, OP/BP 4.37 on safety of dams and OP/BP 4.12 on

involuntary resettlement.

10. Institutional Arrangements: The Ministry of Agriculture and Rural Development (MARD) is

responsible for implementing and managing the entire project. Provinces that perform repairs to dams

in Component 1 and MARD will coordinate activities with the Ministry of Industry and Trade and the

Ministry of Natural Resources and Environment in Component 2. Central Management Board

(CPMU) under MARD is responsible for coordination and overall monitoring of the project. The

implementation of repairs and preparations for the dam safety plan, including protection and

entrustment, is focused on provincial authorities. Provincial People's Committee is the chair of the

provincial level. The Provincial Project Management Unit (PPMU) is responsible for managing and

monitoring the works with support from CPMU. Management Unit of Dam rehabilitation and Safety

Improvement (WB8), Phu Yen province (hereinafter referred to as PMU) responsible for

implementing and monitoring implementation ESIA. The PMU ensures that documents and contracts

for valid bidding include environmental provisions for contractors to comply with. The contractor will

carry out construction activities and comply with the environmental agreements agreed in the contract.

In particular, the contractor will prepare an Environmental and Social Management Plan for the PMU

to review and approve before starting construction. PMU and consultants will closely monitor

compliance with contractor's agreed mitigation measures. In addition, the contractor's compliance will

be closely monitored by Department of Natural Resources and Environment of Phu Yen province,



local authorities and people.

11. Capacity building: During the implementation process, PPMU receives support from CPMU on

the World Bank's environmental safety policy. The PPMU's safety policy staff has been trained by

CPMU in coordination with the World Bank experts to guide the project's environmental safety issues

and World Bank's safety policies. related to the project implementation included: OP 4.01

(Environmental Assessment), IFC's General Guide to Environment, Health and Safety (EHS), OP 4.04

(Natural Habitats), OP 4.10 (Indigenous peoples) and OP 4.12 (involuntary resettlement)…

12. During the implementation of the subproject, training and training on environmental safety

policies for Construction Supervision Consultant (CSC) and EHS staff of the contractor are carried out

regularly to update the relevant information. For PPMU, during the implementation of the subproject,

the subproject will receive regular support from CPMU's independent consultancy and technical

assistance on the management of dam safety risk issues, monitoring the implementation of the ESMP.

13. Public consultation: The subproject has applied different methods and techniques to conduct

public consultations, consultations with people affected and local NGOs by the subproject, including

a) community meetings, b) household survey, c) focus group discussion, field investigation and

interviewing people providing key information. The use of these methods and techniques to enhance

the reliability and effectiveness of feedback from the subproject stakeholders, Especially the local

people are affected and make sure that (i) Affected people receive full information about the

subproject; and (ii) All affected people are involved in the process of freedom consultation, advance

notice and provide complete information during the preparation and implementation process. In

September 2018, the sub-project management board organized a total of 7 community consultation

meetings in the sub-project communes. And there have been official documents sent to the People's

Committees of 7 communes under the subproject to community consultation on environmental and

social protection issues during the subproject implementation process. Participants in community

consultation sessions are representatives of local units and organizations such as: representative offices

of People's Committees, in charge of neighborhoods, veterans' associations, women's union, youth

union, the eldly group ... and representatives of affected households.

14. Cost estimation for ESMP implementation: ESMP implementation cost estimate includes costs

for ESMP monitoring, mitigation measure implementation and capacity building. Mitigation measure

implementation cost shall be included in the construction cost. The following table presents cost

estimates for monitoring and capacity building.

negotiating to get an agreement with the people. Complaints will be negotiated by the parties at all

three stages (People's Committee at commune, district and provincial levels) before submitting to the

court in accordance with the 2011 Complaint Law. PPMU will pay all administrative and legal costs

related to the receipt of the complaint because this payment cost is included in the subproject budget.

15. Information dissemination: In compliance with policy of OP 4.01 and policies of World Bank on

access to information: from the stage of preparing the subproject, relevant information has been

disseminated to community through mass media. PPMU disseminated information and directly

consulted community in September 2018 and sent consultation information to local organizations. The

draft of ESIA in Vietnamese was sent to CPCs to disseminate information and consult in October

2019. The final version is expected to be disclosure in August 2019 through the website of CPO and

website of the Bank in English before appraisal of the subproject.

16. Conclusion: Subproject: dam rehabilitation and safety improvement (WB8) Phu Yen province

may have negative impacts in the subproject phases, but due to the small scale of construction items,



impacts will occur in a short time, The scope in the area is small and insignificant, so the sub-project

has proposed feasible mitigation measures, suitable to the natural, socio-economic conditions and the

conditions of subproject management and construction at localities.

17. The Environmental and Social Monitoring and Management Plan is set up to monitor impacts, to

help stakeholders and local authorities to regularly update the implementation process of subproject

items. The monitoring system is prepared and approved by the WB will apply in the implementation

of subproject, construction supervision consultants regularly check and prepare monthly reports to

submit PPMU.



CHAPTER I: PROJECT INTRODUCTION

18. The Government of Vietnam received a credit from International Development Agency (IDA)/

World Bank (WB), via Loan Agreement No.5749-VN signed on 8 April 2016 for financing Dam

Rehabilitation and Safety Improvement Project. The project is implemented from 8 July 2016 until 30

June 2022.

19. The WB funded Dam Rehabilitation and Safety Improvement Project (DRSIP/WB8) was endorsed

by the Prime Minister in the project list “dam rehabilitation and safety improvement” in Decision

No.1858/QD-TTg dated 2 November 2015 and the Project Feasibility Study Report was approved by

Minister of Agriculture and Rural Development in Decision No. 4638/QD-NN-HDQT dated 9

November 2015.

20. The project has 03 components and total investment cost of USD 443 million, including USD 415

million of ODA loan from WB and USD 28 million of counterpart fund. The funding allocations to

Component 1, 2 and 3 are USD 412 million, USD 20 million and USD 11 million respectively.

- Component 1: Dam safety rehabilitation, budget: USD 412 million.

- Component 2: Dam safety management and planning, budget: USD 20 million.

- Component 3: Project management support, budget: USD 11 million.

21. The project is implemented in three regions: i) Northern region covering the whole Red River

Delta; ii) Central Region covering Central Northern and Middle areas and Central Southern coastal

areas; and iii) Central Highlands area. These are regions with a large number of dams which were built

a long time ago, have rarely received investments for big repair or rehabilitation while being

vulnerable to natural disasters and subject to dam safety incidents.

22. The project shall assist to restore structure of the existing irrigation dams, most of which were

built in the 1980s and 1990s. About 90% of the dams proposed to be rehabilitated are earth and small

ones with height lower than 15m and design capacity of smaller than 3 million cubic meters (MCM).

The proposed project will not support to change the structure or expand the dam for safety securing.

Rehabilitation shall be limited to restoring structure of main and auxiliary dams, stabilizing dam

slopes with concrete slabs or stone paving, strengthening and expanding the existing spillways to

increase discharge capacity, renewing the existing intakes, replacing equipment and power system of

the outlet/discharges and controlled spillway, uniting for leakage control and current access road

improvement.

1.1. Approach and method of implementation

23. The Environmental and Social Impact Assessment (ESIA) was implemented in accordance with

World Bank safeguard policies and in accordance with the Environmental and Social Management

Framework approved by the World Bank. The ESIA process have been carried out in accordance with

the initial screening process to classify the magnitude of the subproject's environmental and social

considerations, impact assessments, propose mitigation measures and establish implementation plan.

And the consultation with stakeholders and information disclosure were also mainstreamed in this

process. In addition, ESIA is also implemented in accordance with the guidelines of relevant safeguard

policies of the World Bank and regulations of the Government of Vietnam. The purpose of

implementing ESIA is to determine the scope, extent and importance of the environmental and social

issue of the implementation of the project, being suitable with the nature, activities and characteristics

of the subproject area to propose management plan and suitable implementation institution to propose

the positive effects and control negative impacts as well as risks from the subproject.

1.1.1. Methods of social impact assessment

24. Social assessment (SA), which is implemented in parallel with environmental assessment of the

sub-project, has two objectives: First, to review potential and negative impacts of sub-projects on the

basis of sub-project implementation plans, and second, to seek potential negative impacts from

designing solutions and proposing community development activities that are relevant to the

development objectives of the sub-project. Identification of negative impacts, and consultations with

localities, Government agencies, project stakeholders, etc. will be undertaken to ensure that affected

people are compensated and supported in a satisfactory and timely manner so that at least their socio-



economic activities are recovered to a level equivalent to that before the project implementation and,

in the long term, their livelihoods will not deteriorate, as a result of the sub-projects.

25. A part of the social assessment is ethnic minorities (EM) living in the sub-project area - they are

assessed and confirmed their presence in the sub-project area through the screening of ethnic

minorities (according to OP 4.10 of the Bank), the people will be informed prior to consultations in an

appropriate manner to determine the support to the community when implementing the sub-project.

Ethnic minority screening is implemented in accordance with the World Bank's OP 4.10 guidelines,

and is conducted within the scope and area of social assessments corresponding to the scope of the

environmental assessment (OP 4.01).

26. A Gender analysis is also implemented as part of the SA to describe gender characteristics in the

sub-project area, enabling the integration of gender issues into promoting gender equality and further

enhancing the effectiveness of developing the sub-projects in particular, and the whole project in

general. Depending on the size of the Project's potential impacts, which have been identified, and the

project development objectives, a gender action plan and a monitoring plan for gender action plan

have been prepared.

27. To ensure that all potential impacts can be identified during project preparation, SAs are

conducted through consultations with various sub-projects stakeholders. An important part of concern

is households, who are potentially affected by the Project (both positively and negatively). The

techniques used to make an SA include (i) reviewing secondary data, (ii) field observations; (iii) focus

group discussions/ community meetings, (iv) in-depth interviews, and (v) household surveys.

1.1.2. Environment impact assessment method

28. During the research, survey and preparation of ESIA report, the consultant team used a

combination of the following research methods.

(1) Rapid Assessment Method

29. The Rapid Assessment Method was issued by the World Health Organization (WHO) in 1993.

The rapid assessment method is based on the nature of materials, technology, the rules of natural

processes and experience to determine the pollutant load.

30. In Vietnam, this method has been introduced and applied in many ESIA studies, which performs

relatively accurately the calculation of pollutant load under limited conditions of instrumentation and

analysis. In this report, the pollutant load coefficients are taken from the WB's Environmental

Assessment Sourcebook (Environmental Assessment Sourcebook, World Bank, Washington D.C,

August 1991).

(2) Impact matrix method

31. The correlation between the impacts of the project activities on each issue and each environmental

component are build and shown in the impact matrix. Based on that, impact studies will be focused on

details.

(3) Comparative method

32. The comparative method is used to evaluate the environmental quality, effluent discharge quality,

pollutant load, etc. on the basis of comparison with relevant environmental regulations and standards,

regulations specified by MONRE and MOH, as well as related research and experiment topics.

(4) Description of environmental system

33. Project components that affect the environment are identified. And waste streams and related

environmental issues are also fully identified for detailed assessment.

(5) Listing method

34. This method has been used extensively (since the National Environmental Protection Agency -

NEPA has been established in some countries) and yielded positive results because of its many

advantages, such as clear approach, acute system during system analysis and evaluation. There are two

main types of listing: one type is a listing table describing environmental components to be studied

and information on measurement, prediction and evaluation, and another type is a simple listing table

consisting of environmental components to be studied that are potentially impacted.



(6) System analysis method

35. This method is applied quite extensively in environment sector. The advantage of this approach is

the comprehensive assessment of impacts, which is very useful in identifying impacts and sources of

wastes. This method is applied on the basis of considering sources of wastes, sources of impacts,

affected objects, environmental components, etc. as elements in a system that are closely related to

each other. From there, the impacts will be identified, analyzed and evaluated.

(7) Community consultation method

36. This method is used during interviews with local leaders and people to collect necessary

information for the Project's ESIA work and present benefits and possible negative impacts of the

Project to the environment and people's life. Based on that, feedback on the project and local people's

wishes will be aggregated.

37. In addition, local officials and local people will be exchanged and interviewed about socio-

economic development situation, cultivation customs and environmental sanitation.

(8) Methods of reference, collecting and analyzing information and data

38. This method aims at identifying and assessing natural and socio-economic conditions in the

project area through the data and information collected from different sources such as statistical

yearbooks, reports on socio-economic situation of the area, current status of the environment and

relevant research works.

(9) Field survey method

39. Field survey is required when carrying out the assessment of social and environmental impacts to

determine the current status of the project area, related objects, and surveys to select locations for

collecting samples, survey of water supply, drainage, electricity supply, etc.

40. The consulting firm has carried out topographical and geological surveys and collected hydro-

meteorological data for design in accordance with the current standards of Vietnam. These survey

results are used to assess the natural condition of the sub-project area.

(10) Expert panel method

41. This method is carried out based on the knowledge and experience of environmental science of

environmental impact assessment experts from the consulting firm and other scientific research

agencies.

(11) Sampling and analysis method in the laboratory

42. Sampling and analyzing environmental components (soil, water, air) are indispensable in

identifying and assessing the quality of the background environment in the sub-project area.

43. After the field survey, the sampling and analysis program will be developed with the following

main contents: sampling locations, measurement and analysis parameters, necessary equipment and

tools, implementation time, sample preservation plan, analysis plan, etc.

44. For Phu Yen sub-project, the consultant coordinated with the Environmental Monitoring Agency

to monitor, collect and analyze samples of air, water and soil in the area of seven reservoirs to evaluate

the quality of environment components. Collecting, analyzing and preserving samples are carried out

in accordance with current Vietnamese standards.

2.5. Auxiliary items

2.5.1. Electricity, water for construction and living

53. Due to the nature of the subproject building gravity water reservoirs, the electricity demand is

negligible, mainly for lighting at night and steel formwork workshops. At present, the national power

grid passes the construction areas, using electricity from the national grid near the subproject area. In

addition, there are 110KVA backup generators in case of power outages.

54. Pumps are used to intake water from the reservoirs to contain in the construction tanks at site.

Depending on the quality of the reservoir water, Contractors will have treatment measures by the

filtering tanks to ensure the water quality for domestic use and concrete construction.

2.5.2. Demand for workers’ houses and camps

55. The demand of workers constructing each item in rush hour is about 60 persons. Almost

construction locations of subproject are favorable for gathering materials as well as arranging labor

camp.

56. Most of construction sites are well located to gather materials as well as to build worker camps.

However, the condition of infrastructure for electricity and water supply is limited, the number of

contractor workers concentrates on the peak time of about 15-20 people mainly managers and skilled

workers, simple work items that directly hire local workers about 20-30 people on a construction these

workers can go home after finishing work, construction time of each item is not long so some

construction are expected to rent premises or houses of local people in each area of the subproject to

build workers' houses, ensuring environmental hygiene and daily living conditions of workers like:

toilets are equipped to meet the requirements of QCVN 01: 2011/BYT on the standard of hygienic

toilet and the individual activities are carried out in the residential areas. At the material gathering

yards are arranged right at the construction site and there are security guards taking turns.

2.5.3. Construction route

57. Advantages: Conditions of construction of works are relatively good, convenient transportation;

At all construction sites, there is road to the reservoir, serving construction to meet the demand of

material transportation during deployment in the locality. Inter-district and inter-commune roads and



routes QL1A, QL25, QL29, DT543, QL19C are all reinforced, very convenient for transporting

materials and ensuring traffic safety.

58. Difficulties: The roads for operation and management of the current Reservoirs are still earth

roads, very muddy when rain occurs causing difficulties and dangers for transporting materials. Some

main roads such as QL1A, QL25... often have high traffic, so pay attention to ensuring traffic safety.

(Photos of managed routes are listed in section 2.2 of this report).

2.6. Pre-construction activities

60. Prior to the construction, there are some works like surveying topography, hydrology,

meteorological conditions, geological drilling, land acquisition marking, UXO clearance. In the

subproject scope there is no demolition of structure but there is the vegetation clearing carried out by

the households that have affected trees and crops. Waste from vegetation clearing will be collected and

transported to the communal dump sites by affected households.

61. Designing the Subproject to provide the options that take into account scenarios, risks of climate

change on the performance of the construction items of the Subproject. The study on the climate factor

change is presented in the section: the recent status of the subproject area, as a basis for selecting

optimal design options. The recent impact of climate change in the region is mainly relating to the

precipitation that results in floods, landslides and droughts.

2.7. Material transportation plan

62. Construction materials will be transported to site about 1 week before the starting of the

construction. Construction materials will be transported to construction sites at certain periods of time

to avoid negative impacts on agricultural activities and the daily life of local people. Workers,

machines and materials are estimated in the sections above.

2.8. Operational and maintenance activities

63. Periodic dam safety monitoring: Once the reservoirs have been filled with water and the dams

started working, the dam-owners are responsible for the dam safety monitoring. This assignment is

carried out by qualified independent experts who did not participate in the investigation, survey,

design, construction or operation of the dams. After the dams regularly operate, the monitoring stages

are kept periodically, including the safety inspections prior and after flood seasons every year in

accordance with the Government Decree No. 114/2018/ND-CP on dam safety management.

64. Upon completion of the works, the operation of the dams will be the responsibility of the dam

owners and the responsibility of the PPMU will end.

65. The reservoir and valve operation procedure: A dam-owner must develop a reservoir water

regulation procedure to regulate the storage and discharge of water in normal and emergency

conditions of dam and reservoir to submit to authorized state management agency for approval and

organize the implementation of the procedure. The dam owners must prepare and submit documents

on operational procedure of valves and each work (hereafter referred to as operation of works) to the

authorities for promulgation according to their competence. Other operations should be addressed

pursuant to the Government's Decree No. 114/2018/ND-CP on dam safety management.

2.9. Dam safety plan

66. A dam safety report (DSR) will be prepared for the Subproject. The objectives of the DSR are to

present, analyze and make recommendations on: a) all conditions that may affect the safety of the

dams and its associated facilities; b) impacts of the dam or substructure breaking or unable to work

due to harsh natural conditions, human errors or structural faults; and c) the institutional framework (at

the present time and in the future) necessary to avoid or minimize adverse conditions for the safety of

the dams.

67. After the completion of the review at the subproject screening stage, the CPMU of MARD should

provide a DSR for each subproject which is identified during the project implementation stage and

sent to the international dam safety (PoE) and the World Bank for review. The report must include

findings and recommendations for any related safety issues and necessary actions to be taken. The

dam safety measures should be integrated into the design, construction and operation of the reservoirs.

68. Review and analysis of the dam structure: The review and evaluation of the dams and related

works will include, but is not limited to, the following:

- Review of the geological documents and material sources, with the attention to potential

adverse effects that may occur by the predictable geological features. Assessment of

unforeseen conditions and counter measures to address the safety and operation of the dams

and the works.



- Assessment of the suitability of the types of dams and spillways, the response of the dam

design. They include the proposed measures for soil treatment, excavation, load characteristics

of selected substrate, seepage and pressure exertion control measures. The safety point of view

for any abnormalities or omissions and measures to be taken will be paid attention to.

- Assessment of the stability, strength analysis and safety factors in normal conditions, abnormal

and extreme load conditions for soil dams and concrete dams, spillway structure and drainage

works, including the determination of geological impact criteria.

- Consideration of the factors of like reservoir stability, landslide formation, waves, and wave

effects on dam stability;

- Consideration of the hydrological calculation method that determines the design flood of the

project, reservoirs and spillway size; review of the designs of the spillways, e.g. the flow

conditions and the tilling basins; assessment of the discharge capacity of the spillways

corresponding to all design flood indicators that dams will not be damaged.

- Considerations for the water intake and discharge works, including hydraulic designs,

emergency dewatering capacity and sedimentation process in the reservoirs.

- Assessment of the design of the spillways and out-door controls, including the selection of the

number and types of outlets and valves, lifting equipment and other controlling mechanisms.

Particular attention should be given to back-up systems to operate spillways which have gates

and draining facilities in the event of operational and power failure.

- Review of the design of the flow diversion works, construction progress, hydrology and the

risk factors associated with the flow diversion during the flow construction and filling process

at the beginning stage of the reservoir water accumulation.

- Consideration of the suitability of the instrumentation, especially those instruments or markers

which are required in the prediction of serious hazards or dam breakage.

- Consideration of the operation and maintenance procedures and the emergency response plan

of the dam owners, including the assessment of sub-project operation and maintenance factors

relating to dam safety and operators’ capacity assessment to be able to perform the

maintenance and inspections of the safety of the dams.

69. Review and assessment of dam safety risks: In addition to ensuring the dam's structure safety, the

project will assess potential risks of the dams to the population and the environment in downstream,

including the related works. Dam breakage may not occur but if it happens consequences will be

serious. Regarding this content, during the project preparation, as part of the DSR or environmental

and social management plan, the sub-Project Owners should conduct assessing potential risks to the

downstream population. For large dams with high-risks, it needs to acquire comprehensive data

during the preparation process, including topographic survey and downstream land use to simulate a

downstream dam and flood breakdown under different conditions/scenarios to serve the preparation of

the emergency response plans. Collecting data from upstream dams and/or watershed activities may

also be necessary for some dams. Planning and implementing capacity building programs for the

subprojects with pilot activities to promote active participation of local communities should be

considered. Communities around the dams can participate in day-to-day monitoring to protect the

dams from external destructors and they can join in simple maintenance tasks. A community

participatory model in dam safety activities should be considered. Sedimentation and contamination of

upstream water may be a serious problem for some river basins. The dam owners must commit to

allocate funds for appropriate dam operation and management and to periodically survey dam safety.

g. Compliance with the environmental and social impact assessment

73. The Subproject‘s environmental and social impact assessment will be carried out in accordance

with the World Bank and the Government‘s environmental assessment procedures. In particular, it will

be subject to the environmental and social management framework (ESMF) of the project that the WB

reviewed and approved. Social and environmental screening will be conducted for each subproject to

determine the appropriate size and type of the environmental assessment. Based on that, TOR will be

prepared for environmental and social impact assessments in accordance with the subproject scope and

the potential impacts anticipated arising from the subproject implementation. Environmental and

social screening will be conducted by World Bank safeguard policy experts. The TOR for the

environmental and social impact assessments will also be reviewed and approved by the World Bank

Safeguard Policy Specialists prior to the implementation of the environmental and social impact

assessments. In the process of the environmental and social impact assessment, consultations with

affected people and local NGOs should be conducted. ESIA will be publicly disclosed at the

subproject sites accessible to locally affected peoples and local NGOs in Vietnamese language the

English version will be disclosed on the WB‘s external website before subproject appraisal.

3.2. The World Bank’s safeguard policies

74. The objective of these policies is to prevent and minimize impacts to people and natural

environment in the development process. The safeguard policies provide basis for stakeholders’

participation in the project designs and act as an important tool for building ownership among local

people.

75. The effectiveness and development of the WB’s projects and programs has been increasing

significantly as a result of attention to these policies. The World Bank's safeguard policies are

available on the website at http://web.worldbank.org, where the environmental protection policies are

3.2.1. Project level

76. The Project’s environmental and social screening has been implemented in accordance with OP

4.01 and indicated that the World Bank's Safeguard Policies on Environmental Assessment (OP/BP

4.01), Natural Habitats (OP/BP 4.04), Indigenous Peoples (OP/BP 4.10), (OP/BP 4.11) Physical

Cultural Resources, Involuntary Resettlement (OP/BP 4.12), Safety of Dams (4.37), Projects on

International Waterways (OP/BP 7.50) and Pest Management (OP 4.09) will be applied to this Project.

According to the screening, the Project is classified as Category A. In addition, it needs to comply

with the World Bank's requirements for community consultation and dissemination.

3.2.2. Subproject level

77. The subproject will only upgrade the dam on the existing reservoirs, has been screened for the

environment and society and determined that: the subproject does not cause major impacts on the

environment and society of the project implementation area. Relevant World Bank policies for the

subproject include:

Environmental safeguard policies

- OP/BP 4.01 Environmental assessment

- OP 4.09 Pest Management

- OP/BP 4.37 Safety of Dams

Social safeguard policies

- OP/BP 4.12 Involuntary resettlement

- OP/BP 4.10 Indigenous Peoples



OP/BP 4.01 Environmental Assessment

78. This policy is going throughout the process of identifying, preventing and mitigating

environmental and social potential negative impacts associated with the World Bank 's lending

activities. In the work of the World Bank, the purpose of the environmental assessment is to improve

decision making, ensure that the project options are being reviewed and sustainable and that the

community to be likely affected must be consulted. The Borrower is responsible for environmental

assessment (EA) and the World Bank advises the Borrower at their request. The borrowing projects

are proposed in four categories, depending on locations, sensitivity, scales of the projects, nature and

extent of potential environmental impacts, including A, B, C and FI.

79. This Subproject activates OP 4.01 as it relates to the construction and operation that will have

social environment potential negative impacts. Based on the results of the environmental screening,

the Subproject is classified B in terms of environment. As defined in OP 4.01 and the Government’s

environmental assessment regulations, this ESIA is prepared for the Subproject to meet the

requirements of the Government’s regulations and the World Bank’s safeguard policies. Upon

appraisal, the ESIA of this Subproject will be publicly disclosed to the local people in the project area

to ensure that affected people and local NGOs can access it easily and it will be disclosed through the

World Bank website.

OP/BP 4.09 Pest management

80. The purpose of the pest management policy is to minimize and manage environmental and health

risks associated with the use of pesticides, to promote and support safe, effective and environmentally-

friendly pest management. The purchase of pesticides in a WB-financed project must be assessed for

the nature and extent of risks involved, taking into account the proposed and intended use. For pest

management affecting one of the two sectors of agriculture or public health, WB supports a strategy to

promote the use of biological control methods and reduce reliance synthetic chemical pesticides. In

Bank-financed projects, the borrower addresses pest management issues in the context of the project's

environmental assessment. In appraising a project that will involve pest management, the Bank will

assess the capacity of the country's regulatory framework and institutions to promote and support safe,

effective, and environmentally sound pest management. The implementation of the subproject does

not increase the capacity of the reservoir, does not increase the irrigated area in the downstream area

and does not affect the crop structure in the subproject area. The repair of the culverts has been

damaged and the loss of water will be overcome to ensure the more stable irrigation water regulation

and will provide adequate irrigation water for the subproject area in the drought season. To restore the

initial volume and area of the reservoirs, then the cultivation of agricultural crops for areas that lack

water in the drought season will be restored, on the other hand, when sufficient irrigation water is

available, it can lead to changes. some plant varieties and planting areas. Therefore, it will increase the

amount of pesticide and fertilizer in the restored area and increase the pest in the subproject area. On

the other hand, the use of chemicals to kill termites in the dam body, if not well managed, also affects

the surrounding environment due to residues and disposal not in the right places or overflowing

rainwater attach termite chemicals.

OP/BP 4.37 Safety of Dams

81. This policy is triggered for the whole project because of the safe operation of dams related to the

socio-economic development and environment. When borrowing from the World Bank for

construction of new dams, a borrower must propose a dam safety policy based on opinions of

experienced and responsible experts in charge of design and construction supervision and that

borrower, by way of the dam safety measures, will implement them throughout the project cycle. This

policy also applies to the rehabilitation and improvement of existing dams, which affect the

performance of a project. In this case, the dam safety assessment should be undertaken and additional

dam safety measures should be proposed. OP 4.37 recommends that, in an appropriate circumstance,

WB staff will discuss necessary measures with clients to strengthen institutional, legal and regulatory

framework for dam safety programs.

OP/BP 4.12 Involuntary resettlement

82. The Involuntary Resettlement Policy is to address long-term difficulties, poverty and

environmental impacts on affected people during a resettlement process. OP 4.12 applies to regardless



of whether an affected person is relocated or not. The WB describes all processes and results of

"involuntary resettlement" or simply resettlement, even when affected people are not required to

relocate. The resettlement is involuntary when the Government has the right to requisition of land or

other assets, and when the affected people have no choice to maintain their current livelihood.

83. This policy applies because this sub-project causes temporary or permanent effects on involuntary

land acquisition, and loss of land-related architectures and assets to build the subproject. After

appraisal, the subproject prepared and disseminated Resettlement Policy Framework and Resettlement

Plan. Resettlement Policy Framework and Resettlement Plan include measures to ensure displaced

persons: (i) be informed of options related to resettlement; (ii) consulted and selected alternative

resettlement plans; and (iii) compensation and livelihood restoration.

OP 4.10 Indigenous peoples

84. The policy of defining ethnic minorities can be defined in particular geographical areas by the

presence of varying degrees of the following characteristics:

- Ties as closely as members of the different indigenous cultural group and are recognized for

this feature by others

- Lives in concentration in an environment which is different from geography or territory

inherited by the ancestors in the project area and to be close to the nature of the habitat and

territory.

- Culture, economy, society or political institutions are different from those of the majority of

cultures and societies.

- Ethnic minority language differs from the official language of the region or country.

85. The required condition for approving the investment project: OP 4.10 requires the borrower to

undertake consultations and disclosures with ethnic minorities that may be affected and establish a

broad community support model for the subproject and its objectives. The project financed by the

Bank shall include calculations to (a) avoid potential negative impacts on ethnic minority

communities; or (b) when avoiding is not feasible, measures should be proposed to minimize,

mitigate, or compensate for impacts.

86. This policy does not apply to this subproject because: In the area, there are 26 AHs directly from

the land acquisition activities of the subproject but not ethnic minorities people.

WBG EHS Guidelines

87. The Environment, Health and Safety Guideline (EHS) by a World Bank Group

(WBG)/International Finance Corporation (IFC) was introduced in 2008. This is an important

guideline on environmental, health and safety protection in industrial development and other projects.

It set out the goals to be achieved and measures to be taken to deliver the best results at reasonable

costs. This Guideline can be found at the website http://www.ifc.org.

World Bank’s policy on Access to Information

88. In addition to the environmental safeguard policies to promote the transparency and the

accountability, WB issued the Information Access Policy relating to proposed safeguard measures. It

sets out the policy to support borrowers’ decision-making by allowing them accessing information

relating to social and environmental aspects of such projects at the website in native language, which

is easy to understand and intuitive. The WB ensures that relevant environmental and social protection

documents related to such projects as well as the preparation procedures related to subprojects are

introduced timely prior to the appraisal. The World Bank’s information access policy requires

disclosure of information in both English and Vietnamese languages and meets the World Bank’s

standards.

1,470m, Hon Chua-1,310m) and South of Song Hinh district (Chu Ninh-1.636m mountain), The

remaining mountains are generally not high, elevation ranging from 300-600m. In the inner city,

although has a mountain not very high, it is very famous because it is located on the banks of the Ba

River, there is ancient Nhan Tower, lyrical landscape, It's Nhan Mountain. Due to the mountainous

terrain, there are many steep passes in Phu Yen. Along the National Road 1A, there are relatively long

and rugged mountain passes, located in all districts. The Phu Yen plain is accreted mainly by three



large rivers: Ba river, Ban Thach river accretion to create Tuy Hoa plain and Ky Lo river to accretion

up Tuy An plain and Dong Xuan, in which Tuy Hoa plain is considered as the granary of the Central

region,

f. Muddy sand flow

103. Due to heterogeneous conditions of flow formation and sand mud the over the entire basin, So

the evolution of sand mud during the year and flood process is very complicated. Average amount of

mud and sand in dry season months is about 150-200 g/m3. In the first floods, the amount of sand is

not very large By the end of October, heavy rains began to appear the basin is eroded more strongly

The amount of mud and sand increases. In these months, the average turbidity is about 1000g / m3. At

the end of the flood season, the amount of mud and sand decreases

4.1.4.1. Extreme weather events in 7 districts under the subproject

104. At the conference "Climate change in Phu Yen province: situation, impacts and responses", in

the presence of many environmental scientists of Vietnam, spent time analyzing and giving an

explanation on the causes of Phu Yen province the regularly of storms and floods. When referring to

the factors affecting the meteorology and hydrology, it often causes floods in Phu Yen, experts from

the Institute of Meteorology, Hydrology and Environment pay attention to Phu Yen's topographical

features and natural conditions. According to engineer Vo Anh Kiet (Hydrometeorology Station in the

South Central Coast), the Central region in general, Phu Yen in particular rainy season coincides with

the period of winter monsoon should combine storm, tropical depression, tropical convergence with

enhanced cold air is the main cause of many heavy rains in the province. Besides, Phu Yen has a 3-

sided terrain bordering the mountain, West is the eastern edge of the Truong Son range. In the middle

of the Eastern flank of the Truong Son mountain range is a low mountain range that runs across the

sea to form Van Hoa plateau is the boundary dividing the two plains built by the Ba and Ky Lo rivers.

Phu Yen also has many steep passes and all kinds of terrain such as plains, hills, highlands, valleys

alternating lower from West to East. These are the natural conditions that govern the hydro-climatic

conditions of Phu Yen.

105. In the same opinion, Senior Lieutenant colonel Nguyen Van Thao, The Head of the Rescue

and Rescue Department of Military Region 5 made a comment: “In the interior of Phu Yen, there are

many mountains with the height of 300-600m creating many passes, slopes and small valleys; There

are many other short rivers such as Cau River, Ky Lo River ... with quite steep slope. In general, Phu

Yen is like a valley of the South Central Coast. Therefore, when there are storms, tropical depressions

operate in the south of the East Sea or land in the Central region, even though Phu Yen is on the edge

of storms, there are also rain and floods. Not only rain in the area causing floods but heavy rain in Dak

Lak, Gia Lai, Southwestern Binh Dinh, Phu Yen is also greatly affected. On the other hand, Phu Yen

soil is mainly rocky, arid, bare hills, thin vegetation (not to mention deforested forestswith this feature

when the rain does not retain water, so creating floods very quickly ”

4.1.5. Biodiversity

106. The subproject is not located in conservation areas such as watershed protection forest, National

park or biosphere reserve or nature conservation area, etc. Therefore, ecological characteristics and

biodiversity locally evaluated for the subproject scope and surrounding areas based on the results of the

current status survey and information provided by local people.

107. According to the results of the evaluation of the current land use status of the subproject, the

subproject area has identified key ecosystems, including:



- Production forest ecosystem: Plantation forest ecosystem, distributed in low hills and

mountains, is planted and exploited periodically, the plants mainly include cajuput,

eucalyptus, and rubber trees.

- Agricultural ecosystem: Mainly rice fields, vegetables and short-term crops such as corn,

beans, peanuts, sugarcane …

- Man-made ecosystem: Including fruit trees such as Avocado, Orange, Pineapple, Coconut

Siamese, Banana, ... and cattle, poultry and domestic animals of households in the land use

scope of the subproject.

- Reservoir aquatic ecosystem: Reservoir aquatic system belong the subproject

- According to the survey results of the Environmental Consultant and refer to the documents

show, In the subproject area, there are no rare and precious animals and plants listed under

Decree 32/2006 / ND-CP, Vietnam Red Book or IUCN Red List.

4.1.5.1. Flora

108. Flora in the subproject's land use area have little diversity of species, according to which the

dominant group of plants, wild plants account for less. Based on the survey results, the subproject area

is implemented by the consulting unit can be divided into groups of plants as follows:

- Perennials: Rubber trees are periodically planted and exploited on forest land surrounding the

subproject.

- Timber trees: Acacia auriculiformis, acacia, eucalyptus, sandalwood, bamboo, hips, apricot,

neohouzeaua, etc. are periodically planted and exploited on forest land area under the scope of

subproject and around the subproject scope. Based on the assessment of the current land use

status of the subproject shows: Production forests are concentrated mainly in the area of

communes. The major crops include acacia auriculiformis and acacia mangium. The entire

area is planted under 1 year.

- Annual crops: Sugarcane is grown and harvested annually mainly in districts Son Hoa, Song

Hinh and Dong Xuan. Around the subproject area, there are also some hilly land that is

cultivated by sugarcane farmers and harvested annually.

- Fruit trees: such as Avocado, Orange, Pineapple, Coconut Siamese, Banana, ... concentrate

mainly on garden land, surrounding residential areas and some scattered trees in the area the

subproject.

- Food crops: Rice, maize, sweet potato, peanuts, beans, ... mainly concentrated on agricultural

land under the scope of the sub-project. Particularly for rice that is mainly cultivated 2 to 3

crops / year, at the time of the survey, rice is being harvested.

- Vegetable crops: Vegetables, Coriander, Basil, ... Focused mainly on the land along the

stream, some low-lying areas and a small part of the garden of households..

4.1.5.2. Fauna

109. The fauna in the study area is very poor in terms of species, there is no record of rare and

precious animal species subject to strict conservation and protection, no species recorded in the red

book

- Domestic animals include: The fauna here is mainly domesticated animals and close to human

life, including cattle, poultry, ... pigs, chickens, ducks, and geese. buffaloes, cows, goats, fish,

...

- Wild animals often encountered in the subproject area are assessed according to information

of local people, including: Reptiles, amphibians (water snakes, frogs, frogs, rams, toads, ...) ,

Insects (with groups of beetles, membrane wings, flakes, jumping beetles, earthworms,

crickets, etc.), Birds (types of sparrows, lime wicks, humps, etc.), but the frequency appears

low and not often.

- In addition, in the subproject area, there is no record of rare and precious animal species

subject to strict conservation and protection, no species listed in the red book.



- Fish: raised in ponds mainly freshwater seabass, Drift fish, crucian, tilapia ...... Fish

production in ponds is not high. Species encountered on Ban Vai stream, crevices and creeks

within the subproject during the rainy season have typical species such as carp, crucian, small

fish, wild fish, commercial fish, ditch fish,….

- Mollusks, living in the bottom area such as screw nuts, stone snails, mussels,...

- Crustaceans: Shrimp, Crab,...

- Overall aquatic animals of the subproject area Mainly fishes reared in ponds serving the of

people, have not high density, catches are low, mainly serving the needs of the people.

Based on the results of the assessment of the current status of biological resources in the subproject

area, mainly forestry and agricultural ecosystems so the species components are usually monotonous,

which are mainly the cultivars and domestic animals of farmers. Within the subproject, there is no

object of conservation, protection and no significant species of flora and fauna of significant habitat

value are affected by the subproject activities.

4.2. The impact of climate change on Phu Yen province

4.2.1. Types of natural disasters often occur in Phu Yen province

110. Phu Yen is one of the South Central Coastal provinces with complex climatic and topographic

features. It is the place most affected by natural disasters in Vietnam such as: Storms, tropical

depressions, floods, flash floods, river bank erosion, coastline, storm surges, cyclones, thunderstorms,

landslides, drought, saline intrusion, … In particular, natural disasters often occur in Phu Yen province

must include storms, floods, droughts, river bank erosion, coastline, high tides:

a. Storms and tropical depressions, tornadoes:

111. As mentioned above, the typhoon season in Phu Yen is determined from September to

December every year, the most is September and November, but there are also typhoons in the end of

December (year 1978). From 2001 to 2014, Phu Yen province had 48 typhoons and 08 tropical

depressions landed and affected. When storms or tropical depressions hit this area, it often causes

heavy rain to heavy floods, fast concentration, landslides carry mud, sand, great devastation to the

mountainous areas as well as spread down to the plains.

b. Flooding:

112. Due to the lower terrain characteristics from the West to the East, the rivers and streams are

short and steep, combined with severely damaged forests, When heavy rains occur, the flooding time

is very fast, causing flooding in most of the delta. Historically, Phu Yen province has experienced a

number of particularly large floods, causing human and property losses in 1993, 2007 and 2009..

c. thunderstorms, Thunder:

113. Phu Yen in coastal areas has an average of 40 days of thunderstorms annually, In mountainous

areas or valleys, there are more days of thunderstorms, about 100 thunderstorm days. Winter season

usually occurs from March to November, in which mainly from April to October.

d. Flash floods:

114. Occurred mainly along the rivers and streams, especially in small rivers and streams, carrying

soil and stones, causing damage to crops, sedimentation, flooded fields, damaging works, especially

transport and irrigation. In 2009, typhoon No. 11 (MIRINAE) hit the southern part of the province,

combined with intensified cold air and heavy rains in the upper reaches of the rivers, especially the Ky

Lo and Cau Rivers, causing severe flash floods. severe damage to the northern of the province

including the districts of Dong Xuan, Tuy An (Ky Lo river basin), Song Cau town (Song Cau basin).

e. landslides at river banks, seaside, high- tides:

115. The landslide situation of three large rivers in the province is very complicated and

increasingly serious, threaten the lives of thousands of households. Districts along the Ba River are

under strong cavitation, landslides have washed away hundreds of hectares of farmland. Whenever

storms and floods occur, river water floods inland dozens of meters. Tide phenomenon and sea

cavitation as well takes place very serious. More than 180 households in Ro village, Phu Dong ward,



Tuy Hoa city are facing with increasingly complicated tides. Since 2003, Ro village has been

cavitation by seawater. Tides often rise dozens of meters high.

f. Drought:

116. Due to uneven distribution of rainfall during the year, 8 months of dry season rainfall accounts

for only 30% of total annual rainfall, there are years almost 02-03 months without rain. Especially in

recent years, due to the impact of climate change, the annual rainfall is inadequate compared to the

average of many years and almost no Manchuria rain so in recent years drought occurred in the

Winter-Spring crop, Especially in the Summer-Autumn crop, drought occurs almost every year, at

least local drought due to insufficient water supply compared to the amount of water evaporated due to

prolonged heat, causing local drought, especially the area at the end of the canal and upland areas.

g. Salt intrusion:

117. The lack of water in the dry season has made saltwater intrusion in Phu Yen become stronger.

In addition to affecting the area of agricultural land, saline intrusion also affects groundwater in some

localities, causing serious shortage of domestic water.

4.2.2. The impact of climate change on Phu Yen province

118. The effects of climate change to Agriculture and forestry production, energy, residence and

livelihood of the people … This is a matter of all levels and sectors of Phu Yen province special

interest. According to Phu Yen Department of Agriculture and Rural Development, In these fields, the

agriculture sector attracts a lot of labor, creates jobs and contributes greatly to hunger elimination and

poverty reduction. Therefore, up to now, the province has built 41 irrigation works and small

reservoirs for agricultural production with an investment of trillions of VND. However, in recent

years, due to the impact of climate change, the average rainfall has decreased sharply compared to

previous years, resulting in a serious shortage of water in rivers and reservoirs, drought land area,

fallow land is becoming more and more serious, causing great damage to agricultural production.

119. Climate change also has the potential to increase the frequency, intensity, volatility and

extremes of dangerous weather phenomena such as storms, floods, droughts, etc… cause reduce

productivity, quantity, number of crops, pet; Increased risk for production, narrowing agricultural land

due to sea level rise and river water were salinization. According to the scenario of MONRE on the

results of assessing the impact of sea level rise in land use in Phu Yen province, the land specializing

in wet rice cultivation is the most affected type in the area at risk of flooding due to sea level rise.

120. It is forecasted that from 2020 to 2030, there will be 700 - 800 hectares, and from 2050 to

2070, there will be 900 - 1,100 hectares of land being submerged due to sea level rise. In addition,

climate change has a serious impact on vegetation and forest ecosystems; increase the risk of

extinction of some plants and animals, degenerating precious and rare gene sources; increased risk of

forest fires and disease spread; On average, 30-40 ha of forest is burned every year. Climate change

also increases the frequency of storms with high intensity, causing sand, sea waves and high tide to

erode banks, desertification of coastal areas; Forest resources are also directly affected, reducing the

forest land area with about 245 - 304 ha (period 2020 - 2030) and from 421 - 543 ha (period 2050 -

2070).

121. In fact, recently, many places in the coastal areas of Phu Yen province have been severely

eroded and tended to increase. Currently, the province has 19 landslide areas with a range of 300 -

1,500m; The annual landslide speed is from 10 to 20 meters, some places are from 25 to 35 meters,

such as Hoa An village, Xuan Hoa commune (Song Cau town), Ro village, Phu Dong ward, Tuy Hoa

city. According to the plan to cope with climate change of Phu Yen province, corresponding to the sea

level of 30cm, the flooding rate is 34.56km2, sea level rise 75cm, flooding rate is 39.998km2 and sea

level rise 100cm, flooding rate will be more than 44km2.

4.3. Environmental status

125. Remarks: Monitoring results showed that air quality in the subproject implementation area

are guaranteed compared to the standard, the area 8 reservoirs have cool climate conditions, vegetation

is production forest, Shrub grows wellThe monitoring parameters are within the limits according to

QCVN 05: 2013 and QCVN 24: 2016 / BYT, QCVN 27: 2010 / BTNMT on ambient air quality (dust,

noise, vibration).

4.3.2. Environmental quality of surface water

126. The results of surface water quality analysis at the works under the subproject is presented in

annex 4 of this report.

127. Results of surface water quality analysis are compared with the following QCVN:

- QCVN 08-MT: 2015 / BTNMT: National standard for surface water quality

128. Remarks: The results of surface water quality monitoring showed that the water quality of 8

reservoirs in the subproject meets the B1 standard for irrigation and irrigation purposes. No parameters

exceed the permissible limits of B1 standard in QCVN 08-MT: 2015 / BTNMT - National standard on

4.4. General socio-economic characteristics of sub-project areas

4.4.1. Socio-economic characteristics of subproject communes

4.4.1.1. Agricultural sector condition in subproject area

(i) Crop structure in agricultural production in subproject area

136. In Phu Yen province, the total cultivated area in the province in 2018 reached over 133,731

ha, increased by 0.9% compared to 2017. In which, the rice area is 56,870 ha, productivity 69 quintals

/ha, 4.7% increase; output of 392,541 tons, increased by 4.8% compared to 2017. Sugarcane area

reached 29,764.1ha, up 6.5%; productivity of 645 quintals / ha, an increase of 0.5%; output of 1.9

million tons, up 7% from the previous year. Cassava area is 23,887 hectares, up 3.6%; productivity of

227.5 quintals / ha, up 4.4%; output of 543,311 tons, an increase of 8.1% compared to the previous

year.

137. As planned, in 2019, the total cultivated area is over 125,700ha. In particular, rice 55,500ha,

yield 66 quintals / ha, output 366,300 tons. The area of sugarcane is 20,000 ha, the productivity is 70

tons / ha, the output is 1.4 million tons. The area of cassava is 20,000 ha, the productivity is 25 tons /

ha, the output is 500,000 tons…

138. In the subproject area, the structure of crops is rice mainly 2 crops at summer-autumn and

winter-spring crops and other crops are sugarcane and cassava KM419.

(ii) Types of chemical fertilizers and pesticides commonly used and utilization rates

• For rice sown:

- Fertilizer amount for 1ha (8-10 tons) of manure, 250 kg of urea, 500 kg super phosphate, 150kg of

potassium chloride.

- Basal fertilizing manure, phosphate fertilizer + 20% phosphate + 30% potassium.

- Apply additional fertilizer 60-70% phosphorus + 20% potassium.

• For transplanted rice

- The amount of fertilizer for 1 ha: 4-5 kg of organic fertilizer is decomposed, urea nitrogen 8-12 kg

6-12 kg potassium chloride, 15-25 kg superphosphate Lam Thao. Specific fertilizers depend on the

type of rice, the nature of the soil.

- Fertilizer for rooted rice (15-20 days after transplanting): 50-80% protein 20-40% K, 5cm flooded

water level.

- In addition to ensuring high and stable productivity, it is necessary to better control some rice

pests such as brown planthopper, stem borer, sheath blight, blast disease.

• For sugarcane

- Sugarcane is a high yielding tree, each hectare per year can give us between 150 and 200 tons, and

it can even be up to 260 tons (there are 200 tons in the Mekong Delta). The growth time of

sugarcane is 10 to 15 months, so nutrients are higher than other crops.

- Normally to produce 100 tons of raw sugarcane (not including buds, leaves ...), the plant needs a

nutrient amount of about 120 kg N, 70 kg P2O5, 200 kg K2O.

- The ratio of nutritional factors also varies according to the growth periods:

▪ The period of preschool (from 1 to 5 true leaves) the most required sugarcane is nitrogen,

then potassium and phosphorus;

▪ In the period of tillering and at the beginning of the period of high growth, the sugar cane

required the most is potassium and then to the phosphate, after is nitrogen;

▪ Period sugarcane ripe (sugar accumulation) demand of sugarcane in N-P-K order.



• For cassava

- Using ROOT 555 preparations to treat seedlings helps to limit the spread of diseases available on

seedlings, increase the viability of seedlings, The root of the seedling grows faster, more and more

productive, the plant absorbs better and more efficiently nutrients in the soil, provides some of the

ammonium acid and trace amounts needed for seedlings, helping Seedlings grow well and have

high resistance.

- Handling seedlings soaking 20-25 minutes before planting.

- When cassava is 2 months old, it is recommended to use herbicide again before fertilizing. This

time is very important to treat the grass thoroughly because if it does not handle the grass, it will

eat food and fertilizer of cassava causing low productivity. – After processing the finished grass,

apply manure and keep the appropriate moisture, fertilize according to the tree and fill up the soil,

the amount of fertilizer is 20g / tree (the dosage is 200 - 350kg / ha).

- Basal fertilizing:

▪ Method 1: All animal manure 2 tons + 150kg super phosphorus / ha, apply when plowing

or applying in rows or holes before planting.

▪ Method 2: Applying organic fertilizer for cassava together with 100kg Super Unicorn and

250kg Sitto Phat 16-8-16-12SiO2 + TE / ha.

- Apply additional fertilizer: Apply one time only after 45 - 60 days after planting: 300kg Sitto Phat

16-8-16-12SiO2 + TE.

▪ Current pesticides are often used: for pests and diseases: Regent 800WP, Karate 2.5EC...

spray when 1-2 year old larvae with active ingredients: Indoxacarb (Obaone 95 WG … ),

Flubendiamide ( Takumi 20WG…), Chlorantraniliprole (Virtako 40WG, Prevathon 5 SC,

Voliam targo 063SC); For disease: Camilo 150SC, Chevil 5SC, Tilt super 300EC, Nevo

330EC, Anvil 5SC, Rovral 50WP, Callihex 5SC, Hecwin 5SC, A.v.tvil 5SC, Til calisuper

300EC,... Currently a number of pest and disease control technologies are applied in the

project area. Rate of pesticide use as recommended by the manufacturer and each drug.

(iii) Implementation of integrated pest management in subproject localities

139. At present, in Phu Yen province, there is Phu Yen Agricultural Extension Center. In all

districts, there are district and commune extension center and in commune, there is farmer association.

The Phu Yen Province Agricultural Extension Center coordinates with other levels to regularly

organize professional training courses for agricultural extension staffs, collaborators and farmers. The

participants are informed about the functions, tasks and technical guidelines. At the same time, the

participants learn how to detect, prevent and treat some common pests, minimize the occurrence and

spread of diseases, minimize damage to farmers and raise production efficiency in the process of

farming. Currently, in the subproject area, it is complied with some basic principles in pest

management as follows:

• Growing and caring for the development of plants:

- Select good and suitable seedling for local conditions.

- Select healthy and qualified trees.

- Plant and maintain in accordance with proper technique so that the plants grow well with high

yield.

• Regularly check and understand the growth and development process of crops, pests, weather, soil

and water for timely remedial measures.

• Farmers become experts: technical knowledge and management skills of farmers need to be shared

with others.

• Pest control:

- Use disease prevention measures, depending on the severity of the disease in each stage.

- Use of pesticides with correct technique



- Protecting natural enemies: Protect beneficial species to kill pests.

4.4.2.3. Education level

177. Education level of people which answered in the interview is very important because it is the



factor that decides the accuracy of the survey. They are the informants providing answers to the

investigators' questions and returning the questionnaires, so there must be a certain level to be aware

of the issues and can answer the related questions. According to the survey results, the educational

level of the respondents is mainly concentrated in the secondary group (40.2%), the primary group

(29.5%), and significantly the college / university group accounts for 9.0% showed that the education

level of householders in the survey area has been improved. Specifically, the information on the

178. In general, the educational level of the people in the subproject area is quite uniform, through

contact of the investigators in the group discussion process with the target groups in the project area, it

could be seen that the ability to participate, contribute ideas to build a community project quite rich,

diverse and real. Therefore, in the process of disseminating content related to the project as well as

public consultation on technical plan proposals, there must be reasonable approaches for the

community to understand the nature and meaning of the project, as well as mobilize participation and

support for the subproject.

4.4.2.4. Occupation

179. According to the survey results, 79.9% of respondents have main jobs in agriculture including

cultivation and livestock (195 people), followed by aquaculture (8.6%), State employees / armed

forces (4.5%), self-employed small businesses (2.5%). In addition, a very small percentage of

households are workers, hired / hired labors and unemployed labors. From this result, in the project

communes, the percentage of households participating in agriculture, forestry and fishery accounts for

the highest percentage, their main source of income is mainly from agricultural/forestry / fishery

production. This greatly determines the stability and living standards of the household. Specifically,

the occupation of respondents in subproject communes is shown in the table below:

181. Household income levels determine household expenditure levels. All interviewed households

are not in poverty. When asked about the average expenditure in the month, there is no big difference

between income and expenditure. Households with large incomes are correspondingly large

investment costs, besides households make farms, when growing sugarcane or trading, the income and

expenditure are always much higher than that of pure agricultural households.

The relationship between income and expenditure of the subproject households:

182. According to socio-economic survey results, the highest average income in Ea Bar commune

(about 126 million VND / household) and the lowest in Hoa Tan Tay commune (about 48.9 million

VND / household). Normally, high-income communes also mean high spending levels. The highest

expenditure is in Ea Bar commune (97.1 million / household) and lowest in Hoa Tan Tay commune

(31.1 million / household). Household income levels determine household spending levels and

household spending levels.

183. In terms of living standards, the poor group is the most vulnerable group, because they do not

have enough money to live, their income depends on agriculture a lot and risk factors of the market

when they have to do unstable jobs to earn a living, etc., … Therefore, during the implementation of

the subproject's work items, the objects are poor households, they are vulnerable they need to be

concerned because if they have to relocate and relocate to a new place, the opportunity to recover



income and maintain their lives is difficult..

4.4.2.6. Housing, land ownership

(i) Housing condition

184. According to household socio-economic survey results, 211 households in the subproject area

own semi-permanent houses (brick walls, corrugated iron / tile roofs) accounting for 86.5%. 5.3%

185. Determining the ownership status, the position of the house in use by households is essential,

for community consultation on the implementation plan of items related to the subproject. At the same

time, is also the base, Legal basis for compensation, policies and options of compensation and support

are suitable for the affected households when implementing the subproject.

(ii) Land ownership

186. For residential land, according to survey results, 95.4% of surveyed households have land use

right certificates. In which, 100% of households surveyed in An Nghiep commune, Hoa Tan Tay, Ea

Bar, Son Ha and Hoa Xuan Tay have a certificate of residential land use right. About 4.6% of

households participating in the survey did not have a certificate of residential land use right. For

production land, 87.2% of households participating in the survey have a land use right certificate, 25

households do not have a land use right certificate (12.8%). Some of the reasons why households do

not have LURC due to insufficient legal basis to prove the validity of the land they live in, though this

is where they have lived for a long time, or a household. In the process of applying for a certificate of

land use rights, or land may be a reclaimed land of the household.

About 38.5% of households use gas for cooking.

189. Roads. The average distance for people in communes in the subproject area to have access to

basic social services such as markets, parks and commune health stations, …is less than 5 km. This is

not too far distance for people to approach. Especially, at present, the quality of rural roads has been

improved much more than before, most of them are concrete roads, which help people to travel in a

way that is convenient and convenient for motorbikes. Average road for people to access social

services as follows:

civilization of the people, one of the important criteria in the implementation of new rural areas.

According to the results of the socio-economic survey, households participating in the survey mainly

use daily-life water for dug wells / drilling (96.1%). Specific information on water sources used in

daily household activities in the following table:

191. Toilet. According to socio-economic survey results, 70.1% of households own septic or semi-

septic toilets. This rate is high in Son Ha commune (100%), it is understood that this is a mountainous



commune, but it is quite benefited from sustainable poverty reduction programs, Program 135 and

rural clean water programs. However, 8.6% of the surveyed households do not have toilets mainly in

Son Dinh commune, Xuan Phuoc is also a mountainous commune with many difficulties, and the

surveyed households are mainly Ethnic minorities. Therefore, the habit of using toilets is also a factor

that increases the proportion of households without toilets. Specific types of household toilets are

shown in the table below:

4.4.2.8. Gender issues in the subproject area

(i) Women's participation in management

192. According to the evaluation of functional agencies, the role and position of women in Phu Yen

province has been increasingly raised, the percentage of women participating in the fields has been

increasing. Women's participation in managerial and leadership positions has been strengthened,

gradually reducing the gender gap in the political field. According to the report of the Department of

Labor, Invalids and Social Affairs of Phu Yen province, in the period (2011-2016), the percentage of

female leaders in the Party, mass organizations, provincial departments and agencies increased.

compared with the previous term: there are 9/52 women participating in the Party Executive

Committee, accounting for 17.31%, increasing 10.04%; 14 out of 50 women are representatives of the

provincial People's Council; female leaders at departments, branches accounted for over 18%; the

team holds the position of head, deputy head and equivalent accounts for more than 24% ... Also from

2012 to now, the percentage of women participating in the XIV National Assembly is 1/6, accounting

for 16.6%. Female delegates of the 2016-2021 term council of the province 14/50 people, accounting

for 28%; district level 60/295 people, accounting for 20%; commune level 736 / 2,944 people,

accounting for 25%…1.

(ii) Gender issues in social association

193. The survey results show that the percentage of men and women who participate equally in

local community activities is relatively high, above 50%. However, in activities, men are still more

involved than women from community meetings, training in production and participation in activities

1 Department of Labor, Invalids and Social Affairs of Phu Yen Province (2016). Report on gender

equality implementation in Phu Yen province



of local socio-political organizations. In fact, because men still stand in the name of the householders,

if the invitation is not invited exactly name, most men will be the participants of the meeting. The

women only attend meetings when the husband / men absent or the householder only participates in

women's associations such as Women's Union, women's interest groups. Meanwhile, other socio-

political organizations such as Farmer's Association, Fatherland Front...the proportion of male

participation is higher.

Table 42: Gender in local community participation (%)


(iii) Women in employment, economic development

194. Accounting for over 50% of rural labor, it can be said that the potential and advantages of women

participating in economic development in Phu Yen province are very large ... The rate of trained female

workers increases steadily over the years. In 2011 it reached 41.4%, by 2013 it was 48.2%; The proportion

of women with university and college degrees accounts for 36.5%. In recent years, Phu Yen province has

many programs to support women in economic development, job creation, and income growth, such as

actively exploiting capital from banks to support women, especially women in rural, mountainous and

disadvantaged areas, with a total outstanding loan of over VND 1,357 billion / 48,366 households; new

development of 4,587 saving credit women groups, creating conditions for difficult women to borrow

investment in production, cultivation and breeding2. Accordingly, the unemployment rate among female

workers accounted for 1.33%, lower than the male group (1.82%) and the overall rate of the province

(1.59%)3. The localities in the subproject area are all rural areas, the main production activities are

agriculture. The agricultural labor structure still accounts for a high proportion, including the female labor

force. Therefore, it is necessary to consider the role of women in employment and to enhance their status,

their voice in society as well as in decisions.

(iv) Division of labor by gender

195. The survey results show that the production activities in the family are not significantly

different, such as cultivation and livestock, with the highest rates of both equal 87.3% and 72.4%.

Meanwhile, other activities such as afforestation, forest product exploitation, aquaculture ..., the rate of

male participation is higher (nearly 50%). Activities that are far away or employed are also mostly

undertaken by men. In contrast, home-based services are mostly undertaken by women.

196. Jobs such as child care, housework, house cleaning are mostly undertaken by women, with

only a small percentage of men responding. This feature is quite common in rural communes in

Vietnam in general and in Phu Yen in particular.

(v) Gender in family decision making

197. Looking at the survey results on gender roles in family decisions, men still play a main role in

decisions such as spending large amounts, deciding career orientation for children as well as in

production investment. Although women are thought to have made significant progress in terms of

social and economic status, gender inequality in family decisions remains a barrier in rural areas,

especially in places where income more depends on men.

Table 44: Gender in making decision in family (%)


4.4.2.9. Ethnic minorities in the subproject communes

198. Ethnic minorities in Phu Yen province are 58,012 people (13,589 households), accounting for

about 6.6% of the province's population) with 31 ethnic groups, mainly Ede, Cham, Ba Na, and Tay,

Nung, Dao, Thai, ... Ethnic minority mountainous areas of Phu Yen province have 3 mountainous

districts (Son Hoa, Song Hinh, Dong Xuan) and 9 mountainous communes of 4 mountainous districts

and towns (Tay Hoa, Phu Hoa, Tuy An district and Song Cau town). There are 45 communes and

towns in the mountainous area, of which 11 communes are in Song Hinh district, 14 communes in Son

4.4.2.10. Assessment of community impacts on HIV / AIDS and intervention measures

(i) Understanding about HIV/AIDS:

201. According to the socio-economic survey results, 60.1% of respondents have the right

awareness about HIV / AIDS as "human immunodeficiency syndrome", 5.2% of respondents do not

know what HIV / AIDS is, and 34.7% of respondents said that this is a pathogenic bacterium.

Total 100


(ii) Awareness about the way of transmission:

202. The survey results show that people's awareness of HIV / AIDS transmission is quite good.

Proportion of respondents who know transmission by sharing needles and unsafe sex is high, all over

90%. However, there are still some incomplete perceptions when HIV / AIDS is transmitted through

mosquito bites, spread by sharing equipment… .

Others 35.4




(iii) Awareness of preventive measures:

203. When asked, over 95% said that they need to live monogamy and use condoms when having

sex with strangers and prostitutes. 77.7% prevented by using separate needles and syringes in all cases.

However, some still think that it is necessary to isolate people with HIV / AIDS and not share the

same bowls with patients. This is an inadequate awareness of how to prevent it from being propagated,

providing adequate information.

Table 49: Awareness of people about HIV/AIDS (%)

Preventive measure Rate (%)

Monogamy 95.2

Living isolated with HIV/AIDS people 23.7

Use needle separately in any case 77.6

Do not shake hands with the patient 10.0

Do not share the bowl with the sick person 28.7

Others 7.5


204. In general, the awareness of the majority of people about HIV / AIDS is correct, but there is

still a certain percentage that does not understand the nature, the source of transmission as well as

preventive measures. Therefore, in the process of implementing the project, it is necessary to pay

attention to the propagation and dissemination of HIV / AIDS knowledge to the people in the

community, especially in the surrounding areas of the work area, with temporary workers in

construction time.

4.5. Sensitive subjects

205. The subproject is carried out in 7 communes, scattered across 6 districts of Phu Yen province,

in the process of deployment will have an impact on the environment and people's livelihood

activities. direction. There are 6/8 works to be noted because the impact in the reservoir area when

repairing and improving dam safety is presented in the table below

CHAPTER 5: ENVIRONMENTAL AND SOCIAL IMPACT ASSESSMENT

5.1. Types and scale of impacts

206. The Subproject to be implemented in the area will cause certain impacts during the

construction stage, however, the impact level is not large and can be minimized. Upon the completion

of construction, the residential areas in the 8 reservoirs will be benefited from the restoration of public

services/facilities, which promote economic growth and access to social services. Important flood

control structures that are roads and dams to be repaired, reinforced, rehabilitated will increase the

safety for people and property in bad weather conditions.

207. Potential negative impacts are identified and screened at each subproject component from the

preparation phase to the operational phase and classified according to the nature of the construction

works. Most negative impacts are temporary, local and reversible due to small to medium-sized

construction scale of the works. Impacts can be minimized by applying appropriate technologies and

specific mitigation measures with the close monitoring of the Consultant, PPMU and local

communities. The table below defines the levels of negative impacts based on the levels of waste

generation by construction activities 4.

247. Potential negative environmental and social impacts are also divided into types such as direct,

indirect, short-term, long-term and cumulative impacts.

Direct Impact: direct impact occurs through the direct interaction of a subproject activity with

environmental, social or economic components.

Indirect impact: The indirect impacts on the environment and society are the impacts that are not a

direct result of the subproject, which is often created later, or as a result of a complex. Indirect effects

are also known as secondary effects, or even tertiary effects.

Cumulative impact: is an impact created as a result of a combination of subproject along with other

projects that cause the associated impact. These impacts occur when the incremental impact of the

4 Based on Decree 155/2016 / ND-CP on sanctioning of administrative violations in the field of environmental protection.



subproject is combined with the cumulative effects of past, present, or future projects that have the

potentiality for predictability.

Temporary impacts: are the effects occurring during the construction or within a short time after

construction.

Long-term impacts: are the effects that arise during the construction process but most of the results

appear in the operational phase and can last for decades.

5.2. Potential positive environmental and social impacts

208. Eight reservoirs under the subproject of dam rehabilitation and safety improvement (WB 8) in

Phu Yen province in 7 districts to serve promotion of agriculture and forestry production,

diversification of crop for mountainous area with difficult condition through ensuring of the need of

water for cultivation, living and production which is linked to natural disaster mitigation measures,

aimed to reduce poverty in the project area.

209. To ensure safety for community in communes in the downstream area of eight existing

reservoirs, the upgrading and repairing of downgraded reservoirs play an important meaning in

ensuring safety of dam and reservoirs and ensuring not occurring risk to 3,414 households in the

downstream area.

210. In addtion, the implementation of the subproject will directly ensure the supply of water for

4,509.05 ha of cultivation area of rice and crop, contribute to increasing quality of cultivation soil,

prevent erosion and desertification, reduce pollution of water resource to contribute to improvement of

social-economic condition in the subproject area, support in implementing National target programs in

six subproject communes, including National Target Program on mitigating and adapting climate

change; Water Resources Development Strategy up to 2020 with a vision to 2050; National Strategy

for Rural Clean Water Supply and Sanitation up to 2020; Program on socio-economic development in

mountainous areas up to 2020; National Target Program to build new rural areas

211. Together with the improvement of access roads and operation road of dam and reservoir, the

subproject also contributes to improvement of travelling condition in the project implementation area,

facilitate trade activities and promote local economic development.

212. Support accessibility for vulnerable communities: With many policies and activities ensuring

that affected parties will be informed, fair accessed to the subproject and the benefits of the subproject,

the subproject will strengthen social activities, facilitate vulnerable groups to participate in project

activities, ensure that the projects will bring maximum benefits to the community under current

conditions and reduce adverse impact on them.

213. In addition, after being repaired and upgraded, the landscape of the area around the reservoir

will be more open, contributing to improvement of the overall landscape of the area. This contributes

to the promotion of tourism services in the reservoir area and head works.

5.2.1. Potential negative social impacts

214. Although the implementation of the subproject will not increase the flooded area compared to

the present status and will not increase the reservoir capacity, subproject’s activities are related to land

acquisition, site clearance and excavation, etc. Therefore, negative impacts from the implementation of

subproject should be assessed and evaluated to propose appropriate mitigation measures.The negative

impact of the project is identified, analyzed, and evaluated based on the scope of the project, the

recipient and the timeframe. Impacts are analyzed in three different project implementation phases: i)

pre-construction phase; ii) the project implementation stage; and iii) the operational stage of the

project. Impacts will also be considered by impact type: direct impact, indirect impact, temporary

impact, long term impact. The level of impact of the project depends on two main factors: impacts that

may arise from project activities and the recipient of these impacts.

5.2.2. Assessment and forecasting of impacts during the process of preparing the subproject

215. Because the subproject works are scattered in different areas, With the scale, the scope of each

works is not large and the duration of the construction is not long . Therefore, the environmental and

social issues in this period are mainly considering environmental factors in the technical design

process of the subproject, land acquisition., land clearance, demining, clearing the site to prepare for



construction. The impacts are analyzed as follows:

a. Assessing the suitability of the project to the natural, socio-economic conditions of the

subproject area:

216. The selection of location, design, and planning of the subproject is made on the basis of

evaluation of the objectives of the subproject in accordance with the natural, socio-economic

conditions of the subproject area. The subproject has studied the plan and scale capacity, suitable

technology with with the area of land occupied to maximize the efficiency of the project's land use and

minimize the impact on the current resources, in the following aspects:

For natural and environmental conditions: Based on the results of the assessment of the land use

status of the subproject, the suitability of the subproject with the natural and environmental

conditions, including:

- Transportation: Approach to subproject is quite convenient by route National Highway,

provincial road, inter-district, inter-commune, inter-village roads ... create favorable

conditions for the transportation of raw materials for subproject construction..

- The current status of land use: The land area of the subproject is largely an area of the

reservoir bed, Traffic land belong the management road … Therefore, it is convenient for site

clearance and investment in construction of work items of the subproject.

- Physical environment components: According to the results of the current status assessment of

environmental components of the subproject area as follows:

o In the subproject area, there are no signs of pollution and no significant sources of

environmental pollution exist for the physical environment components and have not

been much affected by the economic activities of the subproject area.

o When compared with the allowable limit according to QCVN for the current

monitoring results showed the environmental load-bearing capacity of the subproject

area is high, therefore, it will create significant advantages for the development of the

subproject.

- Ecosystems and biodiversity: Ecological characteristics of the area are production forest

ecosystems interspersed with agricultural land, The major crops are acacia, eucalyptus, coffee,

rice and vegetables, … with average productivity. In addition, the subproject land area is not

within the scope of biodiversity conservation areas, biosphere reserve areas and there are no

objects on the list of protection and conservation, etc, … Therefore the impacts on the

ecosystem are not large.

- Socio-economic conditions of the subproject area: The subproject was also studied with the

aim of limiting the impacts on the natural and socio-economic environment in order to

promote beneficial factors and limit adverse factors to ensure objectives and functions and

tasks of the project, specifically:

o –Socio-economy: Within the planning area of the project, there are no architectural

works and technical infrastructure subject to relocation and clearance., At the same



time not resettled people, … Therefore, the project is assessed in accordance with

socio-economic objectives.

o Livelihood: The acquisition of land area is mainly belonging to the reservoir and the

roads are belong the management roads so they do not affect residents and their

livelihood. At the same time, from the downstream dam area of the subproject not

available any significant socio-economic factors affected, the level of damage due to

the right to use water after the dam is minimal.

b) Land acquisition and clearance

217. Because the subproject will only repair and upgrade existing works, The material storage area

is expected to be located in the area of the work protection corridor, so the level of impacts to the

households is negligible. Most of these households build and produce on the corridor of protection of

irrigation works that the People's Committee of Phu Yen has stipulated, all affected households have

judeligible valid residential land. The implementation of the subproject will permanently acquired the

total of 49,274.73 m2 belonged to 16 households and 5 organizations that are People's Committees of

communes, in which::

• Affected land of households includes:

- Land for 2 crop rice cultivation: 771,29 m2

- Land for other annual crops: 1.533,66 m2

- Land for perennial crops: 172,35 m2

- Production forest land: 17.784,36 m2

- Rural residential land: 36,17 m2

• Public land managed by Commune People's Committee: 27,639.3 m2 including 12,428.6 m2 of

other annual crop land and 15,146 m2 of unused hilly land and 64.7 m2 of unused land.

218. In addition, the subproject will temporarily acquired 14,500 m2 to make landfills. The entire

land belongs to public land managed by the People's Committees of communes. Area of camps and

aggregate yards will be used in the dam corridor area of the dam management board. The land mine of

the project will be purchased at the mines that have been licensed and used by competent authorities.

219. There are 15 households that will be affected the trees and crops including: rice, sugarcane,

eucalyptus and acacia. No structures are affected by the subproject.

220. There is no affected household that is severely affected, losing more than 20% of arable land

and houses or from 10% for vulnerable households, No households are in the vulnerable group.

221. Impact assessment: The level of impact of the subproject land acquisition is assessed as

medium, long term because: i) the implementation of the subproject only invests in the repair and

upgrading of works where the worker camp and material yards are expected to be located only In the

corridor of the work protection corridor, the level of impact on households is negligible; ii) most of the

land to be acquired is public land under the management of CPCs in the subproject area.

c) Landmines clearance (UXO):

222. The works of the subproject are spread over 7 communes, 6 districts, Phu Yen province. These

are areas suffered many bombs and mines and explosive objects during the war. Besides, the

implementation area of the subproject has not been in the area of demining before. Therefore, the risk

of landmines / UXO still existing in the land area of the subproject is very high. It is needed to carry

out checking throughout before starting the subproject to avoid unfortunate accidents that could cause

physical damage, affecting the lives of workers, community during the implementation of the

subproject.

223. General assessment of the impact level: High negative impacts, if not considered

appropriately, can affect the safety of people and works, therefore, it is necessary to strictly follow the

implementation steps to ensure a safe works before construction.

d) Impact due to geological exploration drilling

224. Before the plan of design and construction works. The subproject conducted geological

exploration drilling, this process was carried out at all reservoir projects under the subproject.

Specifically, the geological exploration drilling has been drilled in 17 geological boreholes with a

depth of 11-40m at the subproject sites. (Specific locations are presented in the subproject feasibility

study report) to understand the geological conditions and characteristics of aquifers, and conduct

geophysical karota in the borehole.

225. General assessment of the impact due to geological exploration drilling: Low impact

rating. The geological exploration borehole of the subproject has a diameter of 75-100mm, with a

depth of 10-15m. If these bores are not backfilled properly, the pollutants from the surface can follow

rainwater through the bores and affect the quality of underground water in the subproject area.

Therefore mitigation measures are needed to prevent and minimize this impact.

e) Impact due to site preparation activities prior to construction

(ii) Dust and emissions:

226. Dust and exhaust gas are the main sources of air pollution in the preparation stage such as

dust, rock, harmful gases such as CO, NOx, SO2, CxHy.,… arising from activities of transport means

in service of ground clearance transportation and installation of temporary camps.

227. The amount of dust generated varies, depending on the microclimate conditions such as wind

direction, temperature and humidity. According to the World Health Organization (WHO) rapid

assessment method, the amount of dust generated from transport means is as follows:

228. Through the table above, we determine the load of pollutants in the exhaust gas of motor

vehicles according to the average coefficient. With the workload in the preparation stage, the

subproject uses trucks with a payload of 7 - 10 tons to operate, it is estimated that one truck will

transport about 4 turns a day, so the number of trucks / day in the subproject area as follows:

return). So, the pollutant load of transport means operating in the subproject preparation stage can be

calculated as shown in the following table:

(iii) Waste water generation:

234. In the preparatory stage, the daily activities of officers participating in the survey and site

clearance is main source of wastewater. According to statistics, the subproject will use about 5

workers / 1 reservoir, to implement this phase:

- The amount of domestic wastewater generated in a reservoir during this period is:

5 people x 0.15m3 / person x 1 shift = 0.75 m3 / day / night

- All domestic wastewater generated during this period, if not collected, will affect surface water

quality in reservoirs. The impact of domestic wastewater during this period on the 8 reservoir s is

small.

(iv) solid waste:

- Mainly arising from the daily activities of managers and employees in the preparation stage. Trong

In this period, the maximum number of workers concentrated in the subproject area is 5 people / 1

reservoir. According to the World Health Organization WHO, the domestic waste emission

coefficient is 0.3 - 0.5 kg / person / day. Therefore, it is estimated that the volume of domestic

waste generated in this period is 1.5 - 2.5kg / day.



- Thus, the amount of domestic solid waste generated is not high, the main component is easily

decomposed organic waste such as leftovers, raw materials for processing food for workers

(leftovers, fruits, ...) and a small portion of packaging, water cans.

- The amount of domestic solid waste generated during this period is small and scattered. However,

the area for preparation for the subproject construction is located near the water surface of the

reservoirs, so it will have a certain impact on the water quality if proper management and

collection methods are not available.

(v) Waste from clearing vegetation cover:

235. The total occupied land area of the subproject is 21.64 ha of permanently acquired land and

7.59 ha of temporarily occupied land. Of which acacia area is 0.049 ha (about 88 trees with a diameter

of 5 - 20cm), 1.75 ha of eucalyptus trees with about 3527 trees with diameter of 5 - 15 cm. The

remaining mainly bare land, bushes and a small part of growing crops and rice about 0.077ha and

0.15ha of sugarcane.

236. The subproject will conduct cleared of branches and leaves; cleaning shrubs, low biomass

plants on the whole construction area of work items, auxiliary campsite, waste dump, The reservoir

area will be cleaned in a later stage. The amount of biomass needed to be luminescent and clean up is

calculated by the following formula:

M= S x k (*)

where:

- M: Plant biomass, kg. - S: Area of the calculation area (m2).

- k: Plant biomass coefficient.

237. Plant biomass coefficients refer to the survey data on biomass of 1m2 of vegetation cover

according to Ogawa and Kato's calculation as follows::

(vi) Soci0-economc impacts

238. In fact, according to the survey results, there are activities in the area of livelihoods and

economic development (coffee, maize, sweet potato, rice cultivation ...), however only small scale.

Therefore, overall assessment, the impact on people's activities and economic development is not high.

In addition, the subproject has a satisfactory compensation plan after reaching agreement with the

affected population (About 16 households lose land)..

239. In addition, during the construction of site clearance, due to the concentration of a part of

construction workers, indigenous people can benefit from the provision of simple labor and trading of

necessities for living.

240. The subproject is also studied with the aim of limiting impacts on the natural and socio-

economic environment in order to promote beneficial factors and limit adverse factors to ensure

objectives and functions and tasks of the subproject, specifically:

- –Socio-economy: Within the planning area of the subproject, there are no architectural works and

technical infrastructure subject to relocation and clearance, and not resettlement, etc. … therefore,

the project is evaluated in accordance with socio-economic objectives.

- Livelihood and economy: Land acquisition is mainly of the land belonging to the reservoir and

traffic soil belong management road so it has no impact on residents and their livelihood. At the

same time, from the downstream dam of the subproject no significant socioeconomic factors were

affected, The level of damage caused by the right to use water after the dam is minimal.

5.2.3.2. Impact on air environment

a. Arising sources

242. Activities that generate dust and emissions that can affect air quality, include: i) Excavation of

soil and embankment of the works; ii) Operation of construction equipment at construction sites; iii)

Operation of transport vehicles;

b. Impact assessment

243. The level of dust and air pollutants during construction of projects under the subproject

depends on the demand for fuel use, excavation of soil and embankment and mobilization of

machinery and equipment on construction sites. According to the subproject design documents, the

main needs related to dust generation on site are listed in the following table:

246. Dong Tron reservoir: The amount of raw materials converted on an average of 1m3 is

equivalent to 2.5 tons. Therefore, the total amount of bricks, cement, iron and steel, and other

materials is: 15,867,254 tons, equivalent to 6,346.9 m3.

247. The total amount of dust emitted from material transport activities during this period is:

0.1×6,349.6 ÷ 1×6,349.6 = 634.96 ÷ 6,346.9 (g) = 0.635 ÷ 6.35 (kg).

248. The supply of raw materials is made based on the construction progress. The construction

period of the entire subproject is 27 months, equivalent to about 810 days. Average daily dust load is:

0.0023 ÷ 0.023 (kg / day).

249. Similar to the calculation with the remaining lakes, we have the following table:

252. Compared with QCVN 05: 2013 / BTNMT, the limit value for average TSP is 0.3 mg / m3,

then which is much lower, This shows that the dust from the transportation of construction materials

of all 8 reservoirs at peak time is lower than the permissible limits between 10m and 100m.

Dust and emissions from the operation of transporting vehicles

253. The total volume of raw materials to be transported is shown in Table 51. Using transport

vehicles is truck 7-10 tons.

254. The pollutants being created by activities of vehicles include: Dust, SO2, NO2, CO, VOC,

noise, vibration ... The load of pollutants is shown in the table below:

266. Through the above data table, we see that at a distance of 10m, compared with QCVN 05:

2013 / BTNMT, the concentration of pollutants such as NOx in lakes of Dong Tron, Phu Xuan, Dong

Khon, Hoc Ram, Hon Dinh all exceeded the permissible limits. from 1.5 to 2.5 times. Concentrations

of other pollutants such as Dust, SO2, CO, in all remaining lakes are within the permissible limits.

267. At a distance of 100m, compared with QCVN 05: 2013 / BTNMT the concentration of

pollutants is within the permissible limits. Concentrations of other pollutants such as Dust, SO2, CO,

NOx in all lakes are within the permissible limits.

Concentration of pollutants through excavation and embankment

268. In the construction of subproject work items, diffuse dust arises mainly from the following

activities: Digging and embankment, shoveling soil, stone by machine; transporting soil and stone; etc

…

269. According to the estimation, the volume of excavated soil is shown in section 3.1.2 of this

report. Through the data of excavated soil and embankment, we have the following results:

270. Dust emission factor due to excavation activities in construction is shown in the following

table:

271. Based on the pollution emission coefficient in the above table and the volume of soil and stone

in the work, we calculate the amount of suspended dust flying into the air during the construction of



the subproject (Working time 8 hours / day, 27 months corresponds to 810 days) as follows:

272. Dust concentration of excavation and embankment activities is calculated through the

following table (With a construction area of 2.5 ha and an altitude of emission of 10m):

273. From the results of the above calculation, comparing with QCVN 05: 2013 / BTNMT shows

that the average dust concentration during the peak period in the subproject construction area, the

concentration of dust due to excavation and embankment activities exceeds limits permission term.

Therefore, it is necessary to have mitigation measures during the excavation and embankment.

Impact of dust and emissions from the operation of 30m3 / h concrete batching plants

274. During the operation of the batching plant, the source of environmental pollution is mainly

caused by the dust emission source:

- Material preparation stage: Dust generated by unloading during mixing of materials. The source of

dust is scattered, not concentrated and not large.

- Mixing step: After quantification is complete, the mixing jar rotates. Workers transport materials

to the batching plant (In case the mixing tank still concrete or the outlet of the mixing tank is not

closed, the control system will not work). When a worker reaches the location where the material

is poured into the mixing container, the material is poured into the mixing container and the

cement is discharged. When the concrete is finished discharging, Workers will return to the scale

frame to carry out the next batch, simultaneously discharging water and additives.

- Forced mixing time is about 30-45s. After mixing time, the concrete mixture is discharged into the

conveying device.

275. The main subjects affected by dust pollution from concrete mixing plants are 2-3 workers



operating the mixing plants and workers loading materials for the mixing plants. Due to small mixing

plant only 30m3 / h and little construction work volume. On the other hand, the batching plant only

operates for a very short time during the construction process. So the impact is low. However, there is still a

need for measures to prevent and minimize dust for workers performing the plant operation.

c) Assess the impact level: moderate and controllable.

276. The results of the above impact analysis show that the concentration of dust and some air

pollutants exceeds the permissible standard within a distance of 10m from the boundary of the

construction works. However, according to the results of the site investigation, the construction works

of the subproject are located very far from the residential area, the nearest residential area is about

500m from the construction site. According to the calculation results, dust generated from vehicles

does not exceed the permissible standards, However, in fact most of the roads to the site have many

gravel roads, based on experience from many construction subprojects, which shows that the activities

of construction trucks on these roads often generate dust very big. Besides, the surrounding area is

agricultural land planted with coffee, rice, corn ... of the community, open spaces, types of air

pollutants easily diluted. As a result, the two affected objects are construction workers and families

near the gravel roads that operate the subproject's vehicles. However, these impacts can all be

mitigated through appropriate mitigation measures.

5.2.3.3. Impact due to noise and vibration

a. Source of impacts

277. Noise, vibration is generated from construction activities on site; transportation of materials;

construction machines.

b. Impact evaluation

• Impact by noise

278. Noise sources mainly from operation of bulldozers and trucks. Based on the typical source

noise level of the equipment (the following table), it is estimated that the source noise level is 80.8 ÷

96.6 dBA according to the formula:

L= 10lg n

281. Where: L - noise reduction level at distance r2 from noise source; r1 - distance of sound level

is typical for noise source (r1 = 8m); a - coefficients include the influence of the noise absorption of the

terrain (a = 0,1 - the ground has grass).

282. Based on the above formula and input noise level in the above table, we can calculate the

result as follows:

283. Based on the results of noise propagation forecasting for independent noise sources used in the

subproject construction, it is showed that:

284. When compared with the permissible limits according to QCVN 24/2016 / BYT - National

technical regulation on noise - The level of exposure that allows noise in the workplace, most devices

with noise propagation are within Permissible limit ≤ 85dBA at distance <5m from noise source.

285. When compared with the permissible limits according to QCVN 26: 2010 / BTNMT -

National Technical Regulation on noise, the equipment with average noise propagation of 1 hour



reaching the permissible limit ≤ 70dBA during the day is at ≥ 20m from source. However, when

compared to the night time limit, the distance to ensure noise propagation from <50dBA devices is

mostly at distances> 50m from the source..

286. Calculating the noise propagation taking into account the resonance of the machines on the

site, the noise value is about 85.4 dBA at a distance of about 5m from the noise sources. Evaluation

results at distances ≥ 10m, noise meets QCVN 24/2016 / BYT - National technical regulation on noise

- Permissible level of noise at workplaces and at distances ≥ 40m is valuable total value is less than the

allowable limit in the daytime according to QCVN 26: 2010 / BTNMT - National technical regulation

on noise.

287. The above evaluation results show that the noise from operating construction equipment has

low to moderate impacts on the surrounding environment. However, due to the frequent, prolonged

impact along with the operating time of equipment in construction, the impacts on the health of

workers are regularly present at the subproject and dand directly implement construction the impact

level is significant when regular, long-term exposure is required.

• Impact due to vibration

288. Same as noise, vibration depends on many factors such as equipment condition, construction

conditions and measures, so that there are no adequate studies on vibrations of construction activities

at present. Therefore, we use the vibration standard for all kinds of vehicles and construction

equipment of the "US Environmental Protection Committee - Noise from construction equipment and

NJID construction equipment, 300.1, December 31, 1971" on the vibration level at the source, as well

as using the waveform vibration propagation forecasting model like the above noise with appropriate

adjustment factor to serve as a basis for evaluation for construction:

289. To forecast the amount of vibration attenuated by distance, use a formula:

L = L0 – 10lg (r/r0) – 8,7a (r – r0) (dB)

Where:

- L is the vibration in dB at a distance "r" meters away from the source;

- Lo is the vibration in dB measured at a distance "ro" meters from the source. Vibration at a

distance of ro = 10 m is generally acknowledged as source vibration.

- a is the intrinsic vibration reduction coefficient with clay ground of about 0.5.

290. Based on the vibration of construction equipment and application of the above formula, we

can predict the vibration level as shown in the following table:

Note: QCCP - Permissible standard according to QCVN 27: 2010 / BTNMT - National technical

regulation on vibration


291. With these values, when compared with QCVN 27: 2010 / BTNMT - National technical

regulation on vibration, it is showed that the types of vibration-controlled equipment include: earth

construction machines (excavators, crane, excavator ...); types of compactors, piling, drilling

machines, chisels ...

292. The average equivalent vibration level at the source of the average construction equipment of

all devices is about 59dB, the total vibration level near the source is about 81.0dB. The propagation of



vibration of devices with values within the permissible limits according to QCVN 27: 2010 / BTNMT

- National technical regulation on vibration at a distance of less than 5m from the source location.

c) Impact assessment: Average negative impacts and can be controlled.

293. Based on the results of the current status assessment of the subproject area, it is significantly

away from the surrounding residential areas, and no buildings, structures are affected So the impact of

vibration on the environment is not great. However, vibration created by operating equipment is likely

to directly affect workers on the site and especially those who directly control the construction

vehicles and equipment of the subproject..

5.2.3.4. Impact on water environment

a. Source of impact

294. The following activities create waste or impact factors likely to affect water and sediment

objects in the subproject area, including i) Overflowing rainwater with mud from construction site ii)

wastewater from worker activities; iii) wastewater from concrete mixing activities; iv) Construction

waste water. (v) Greases, chemicals used in construction

b. Impact assessment

295. Domestic wastewater from worker camps includes wastewater from water used for preparing

meals (Vna) and washing and cleaning (Vtg). Based on standards of synthetic water use per capita

including water used for eating and drinking and living in rural residential areas follow: "TCDXVN

33: 2006 Water supply - Pipeline network and design standards", water level used for living and eating

is 80l / person / day and 80% of water used will be discharged into the environment (Item a, Clause 2,

Article 39 of Decree No. 80/2014 / NDCP August 6, 2014 on drainage and wastewater treatment).

Construction waste water is generated by: Concrete mixing station; washing stones and sand; concrete

maintenance, washing machinery. The amount of construction waste is generally not high, with the

major pollutants are sand, stone, and cement, which are of low toxicity, easily deposited on the

construction drainage route. Estimated construction wastewater is about 15m3 / month for Gieng Tien

reservoir works:

296. Water environment can be polluted by waste water containing high organic components

arising from daily life, sediment, oil and grease in construction waste water, rainwater running through

the surface of the workplace to remove the dirt, rock, soil and other grease. Water parameters such as

turbidity, suspended solids, nitrate, sulfate, BOD5, COD, total coliform will increase significantly and

reduce water quality in reservoirs and downstream areas.

297. Domestic wastewater: Domestic wastewater in construction arises mainly due to the activities

of workers on construction sites. Due to the characteristics of the location of the subproject

construction sites, the workers camp will be located on the construction site. According to the above

table, the volume of domestic wastewater (estimated at 80% of total water use) will not be high, but

this type of wastewater will contain typical pollutants such as BOB, TSS, total Nito, total phosphorus,

Coliform, fecal coliform, helminth eggs play the role of disease transmission. This source of receiving

domestic wastewater is surface water in downstream area of reservoirs under the subproject. The

current status of the downstream surface water environment according to the monitoring results is not

yet polluted.

298. Construction waste water: from the construction of main construction items such as dams,

spillways, culverts due to construction conditions, it is necessary to apply measures to crank up dikes,

leading the flow, thus generating large water pit such is continuous pumping during construction, this

is also considered construction waste water because the water has been turbid due to earthworks and

rock excavation, which may contain oil, grease, cement. Estimate the total volume is not high, only

focus on the period of activities related to concrete. The body receiving construction wastewater is the

surface water environment in the reservoirs under the subproject due to construction of intake,

upstream slope and downstream surface water due to construction of downstream slope, Spillway, and

Management road. On the other hand, the soil environment in the construction site area may also be

polluted due to construction waste water. The status of soil and surface water in the subproject area

has not been contaminated.

299. Wastewater from concrete batching plant: Due to the production process of concrete batching

plant is fully automatic and self-contained, in addition to the not use of chemicals in the process of

using and and limiting waste water generation. The operation of the concrete batching plant is installed

with modern technology imported from Thailand so the wastewater generated is almost impossible

because the concrete mixing ratio is available and closed. Therefore assess the impact level from



concrete batching wastewater is Low.

300. Stormwater runoff: The composition of stormwater runoff is very difficult to predict and

change according to the time of rain, mainly concentrating high concentrations in the early stage of the

rain. Pollutants in stormwater runoff at the construction phase are mostly natural stone components

due to construction and a small amount of domestic waste scattered on the surface. Applying the

formula to calculate erosion coefficient according to the formula of Wischmeier (Nguyen Van Nhung

(editor), 1997: Map of potential soil erosion in Vietnam (the mainland scale of 1: 1,000,000). Institute

of Geography, National Center for Natural Science and Technology, Hanoi, 40 pages):

100K= 2.1.10-4M1,14(12-OS) + 3.25(A-2) + 2.5(D-3)

Where: K is the coefficient of soil erosion (%); M is the grain weight, defined (%) M = (% Limon

+% fine sand) (100% -% clay); OS is the content of soil organic matter (%); D is the coefficient of

dependence on soil permeability; A is the coefficient depending on the shape, arrangement and

type of soil structure.

- Based on the rainfall of the subproject area, the slope and the composition of soil and rock,

applying the level of soil erosion without grasses for the excavation and embankment areas,

the erosion coefficient is calculated as 0.18% (For soil group yellow-red). Relatively

forecasting the amount of potential eroded soil generated at the construction sites for Phu

Xuan reservoir: The total potential soil erosion during the construction process of Phu Xuan

reservoir (m3) = Total excavated volume Covering during the construction process of reservoir

Phu Xuan: Volume potential soil erosion (m3) = Volume of excavated soil and backfilled soil

(m3) * K (0.18%) = 71,747.48*0.18% = 129.15 m3. Similar to the remaining lakes, we have

the forecast results of potential soil erosion during the subproject construction process as

follows:

301. Oil, grease, chemicals used in construction: Using chemicals to kill termites in the first stage,

change oil, wash machinery and equipment on site .... The area for washing and cleaning machines

and equipment on site of the project is located near the entrance of the project. Wastewater from this

area arises mainly: Waste oil from periodic oil change; Water for vehicle maintenance and car

washing; Solid waste contains oil from the operation of motorcycles and maintenance activities ...

302. Wastewater from drilling operations to treat seepage of dam body: Mixed mortar is

composed of small solid particles suspended in liquid solvent. Belonging to this type there is the

mortar cement, i.e mixed cement with water; Mortar soil-cement forms from soil mixture and cement

with water, and bentonite mortar consists of a mixture of bentonite in water. Cement mortar is widely

used and is often a mixture of water and cement in a ratio of 10: 1 to 2: 1. If this mixture of slurry

during the treatment of seepage and spillage occurs in the environment, it will affect the surface water

of the lake and surface water in the downstream area of the dam, such as showing the ability of mortar

It causes contamination of groundwater, surface water when encountered and adverse health effects

for workers during manual grouting. Absolutely do not allow toxic chemicals in the grout. This is

particularly noticeable when there are additives and is determined by the tightness and safety of the

additive device combined with the appropriate durability.

c. Impact assessment: negative impacts are medium and can be controlled



303. Subjects are mainly affected by water pollutants in the area where the works are under the

subproject will be the surrounding water bodies and soil environment. However, according to the

survey results in the field, the area around the reservoirs does not have ponds, lakes and rivers flowing

through. However, the construction works are located in areas with a certain slope. Wastewater from

camps affects the area around the camp site, This is an unoccupied area under the management of

CPCs, so the direct impacts are very low, however, this is a source of disease and communicable

diseases from workers. Wastewater from construction activities, and from construction equipment

maintenance activities on works (if possible) affect only within the construction site. Appropriate

control measures are required.

5.2.3.5. Impact of solid waste

a. Source of impact:

304. Solid waste from construction activities of sub-project was derived primarily from: i) Waste

stone and soil from excavation and backfilling activities during construction; ii) domestic waste from

worker activities; iii) Hazardous waste from related activities.

b. Impact assessment:

305. The volume of solid waste generated depends strictly on the volume of excavation and

embankment on the construction site, the number of workers to be mobilized on sites, construction

management, construction skills of workers on sites. Total construction waste and domestic waste

generated from construction activities of the subproject are estimated in the table follow:

Table 85: Estimated volume of excavation, embankment and domestic waste generated from

subproject construction activities

stone to be dumped (m3 )

7 Hon Dinh 6,774.23 1,440

8 Hoa Thuan 945.37 720

Total 75,102.96 8,400


306. According to the above table, the volume of excavated soil that cannot be reused on

construction site, needs to be transported and disposed is very little for each construction item, this

amount of waste is mainly generated in the first phase of construction works. The estimated monthly

domestic waste is not much, however, the calculated volume is applicable to the number of workers

mobilized on site at peak times, while the actual number of workers required daily on construction will

be less.

307. For hazardous wastes (HWs): According to statistical results, the volume of hazardous waste

generated mainly in the subproject construction phase includes waste metals, oil-contaminated solid

wastes, paint sludge, ... The impacts of hazardous solid waste are assessed at high level and probability

of occurrence. However, because the volume generated from the subproject construction is not high

and the strict implementation of hazardous solid waste management measures, the probability of

impacts is limited to the lowest level. In addition, according to the design plan, the use of termite

chemicals will be carried out at all the subproject sites. Accordingly, Metavina 10DP is expected to be

used, and if it is not well managed, there will be risks of water and soil pollution around the

construction sites.

c. Impact assessment: negative impacts are medium

308. Subjects receiving impacts from solid waste are mainly soil, water, air and public health

environments. However, according to the survey results, the area around the sub-project does not have



water bodies, rivers and streams that may be affected by generated solid waste. The impact on

groundwater quality requires a long-term infiltration period and a larger amount of arising. For the air

environment, some toxic odors and gases (mainly H2S) can be created, however, with airy conditions,

these toxic gases are easy to dilute to the threshold of no impact. For public health, the survey results

also show that there are no household living within 500m from the construction site. Therefore, it

mainly affects workers and officials on the construction site. The dispersal of solid waste of different

types will have cumulative effects on other activities in the region over time that may cause flow

congestion or unsanitary environment, requiring appropriate management measures.

5.2.3.6. Impact on surrounding agricultural cultivation areas


309. Areas of surrounding agricultural land will be affected by: i) mud flow arises due to erosion in

the construction area when there is rain; ii) Excavated soil and embankment soil, stone, construction

materials spilled out of the works; iii) Waste disposal activities are not well managed; iv) operating at

land mines causing spillage of soil to surrounding areas.


310. Mud flow is generated by erosion at the construction site of the main dam, spillway and some

management road sections. It is estimated that in the rainy season, the potential eroded soil volume per

meter of construction foundation is forecasted to be: 0.37m3. This amount of soil has been liquefied by

rain, easily overflowing to the low areas around the structures. Potential impacts during soil

excavation and embankment (about 12 months for each construction site) mostly happen in heavy rain

period (September-December).

311. In addition, as calculated in the design dossier of the subproject, most of the excavated soil

will be reused for the foundation embankment. Therefore, the amount of excavated soil will need to be

gathered on the construction site before being implemented for the purpose of backfilling. If this

activity is not well managed, there will be a risk of spilling into the surrounding areas affecting the

farming activities of households close to the construction site.

312. In addition, the area of agricultural land around the disposal area and the soil pit area will also

be affected if measures to manage soil spills are not well implemented.

c. Impact assessment: negative impacts are medium

313. : Since all construction works in the subproject are located in the agricultural cultivation area,

the impact on this activity may occur, however, the level of impact is not significant because: i)

According to the results of the field survey, the areas surrounding agricultural land are mainly

cultivated with coffee and fruit trees, so the impact of soil and rock dumping from the construction site

will be limited, the cultivation area of paddy rice, maize and crops is quite far from the construction

works; ii) The area of construction works with a temporary ground, arranged around the construction

area are mainly the land managed by the People's Committees of communes, so the activities are less

likely to exceed the boundary of site clearance of the construction site; iii) According to the

estimation, most of excavated soil will be used for backfilling, so the volume of waste soil and the

need for additional soil will be very small, besides, unused soil will be disposed in many different

disposal areas, therefore, the size of the disposal area will be very small, quite similar to the land

exploitation activity carried out at many different pits, which are close to construction sites

5.2.3.7. Impact on traffic and traffic safety issues


314. The following activities may affect road traffic activities, including: iii) construction activities

at the reservoirs; ii) Transporting materials across National highways, provincial roads and local roads

causing slippery and damage to community utilities;

b. Impact evaluation

315. Obstructing community traffic: Currently, the dam routes are the roads of local people moving

around. Therefore, when subproject construction will directly affect the travel of people on this road.

Therefore, the project owner will take reasonable measures to regulate traffic so that people can still



walk during construction.

316. The risk of traffic collisions on transport routes: Vehicles carrying materials and waste from

material mines / yards and construction areas will lead to soil sticking on the tires. Spilled soil on the

road will generate dust and will also mixed with water. Mud layer on the road surface creates slippery

conditions and increases the risk of traffic insecurity. In addition, the increase in means of transport on

inter-village and inter-commune roads creates a great risk of traffic collisions between the subproject

vehicles and the local community's vehicles.

317. Damage and degradation of roads: According to calculations in the design dossier, the roads

for transportation activities are national highways, district roads, inter-village roads. For inter-village

roads, the transport distance varies from 900m to 3km, currently the roads are in very low loading

capacity, easily affected by the operation of large transport vehicles.

c. Impact assessment: Negative impacts are moderate and can be controlled through an appropriate

impact management plan.

318. According to the survey results, the structures under the subproject are located in remote areas,

the roads are very limited. So the local community is using operating route and the main dam, spillway

at the construction works as internal roads, so the construction on these locations will hinder the travel

needs of the community, it is necessary to have appropriate traffic management measures.

319. In addition, it is expected that some inter-village roads will be used as transport roads,

currently these roads are at very low loading capacity, the increase in the operation of vehicles with

large loads will cause degradation of the road surface and disruption of horizontal drainage culverts,

irrigation ditches along the edge of the road. There is a need to assess the initial status, commitment

between project owners, contractors and local authorities.

5.2.3.8. Impact due to raw material exploitation

a. Source of impacts:

320. Due to the exploitation of embankment soil under the subproject, This activity is carried out in

8 surrounding mines.

b. Impact analysis

321. The proposed land mines for construction works are defined in Section 2.2.3 of this report.

However, according to calculations, the demand for land for each works is very few. The necessary

procedures for taking soil at these mines have been implemented. Activities of soil exploitation at soil

mines will cause some impacts on the environment such as affecting the surrounding agricultural land,

breaking environmental landscape, losing vegetation cover ....

c. Impact assessment: negative impact is low

322. The impact of construction material exploitation is very low, due to the following reasons: i)

most of the materials purchased, only the fill soil will be taken from the local mines; ii) the need for

filling soil in very small lakes, most of the mines are located around the lake; iii) vegetation in these

areas is only grass and shrubs and there are no rare species need to be preserved; iv) The location of

those mines is under the management of the CPC, away from the agricultural cultivation areas of the

community.

5.2.3.9. Impact due to dumping soil and stone


323. Waste excavated soil stone types that must not be used on construction sites are gathered at

regional disposal areas.


324. Waste stone and soil are organic soil and plant roots arising from the excavation of road and

soil generated from soft soil treatment areas. The type of soil and rock that does not meet the material

requirements of the subproject should be removed and contains no harmful ingredients. This is a good

source of materials that can be used to level the civil areas without high requirements on the base

material. Like excavation, embankment and material transportation, in addition to the impacts arising



during the transportation process, waste soil in the construction areas can also spill into adjacent areas

causing the situation to be buried or muddy.


325. Impact from this activity is assessed to be low due: i) The excavated soil and embankment soil

that needs to be dumped is organic soil with no toxic ingredients; ii) The amount of soil to be dumped

is small; iii) scattered waste disposal activities in many different locations; iv) The area of planned

disposal sites is the vacant land under the management of the Commune People's Committee or land of

some households wishing to level up; v) The vegetation in these areas is only grass and shrubs and

flora and fauna, no rare species need to be preserved.

5.2.3.10. Impacts due to gathering workers


326. During the construction of the subproject, a large number of workers from other localities will

be concentrated during the construction period. The emergence of this number of workers and living

activities and work of this workforce will have a significant impact on the lives of local people. The

appearance of a number of male workers will show the following evils in the locality: (i) Local order

and security may have disturbances;(ii) Cultural conflict between workers and local people (iii)

conflicts, conflicts between workers and local people; (iv) appear social evils such as gambling,

alcohol, use of stimulants; (v) There is a risk of overcrowding in health services, public services, and

food for workers.... The bad management of workers will lead to many negative issues. As has

happened before in some subprojects. Workers and people have conflicts that, if not resolved, also

cause fighting conflicts that affect the body, and life....

b. Impact evaluation:

327. The risk of spreading diseases: due to poor sanitation in temporary houses and the camping

area in the construction area will lead to diseases such as dengue fever, eye disease ... of workers, then

spreading widely to surrounding residential areas. In addition, there is the possibility of spreading

social diseases such as HIV / AIDS by other local workers and vice versa, infected workers from local

residents.

328. Conflict arises: Conflicts may occur between local people and migrant workers due to cultural

differences, lifestyles, voices, regions. In particular, in the local community of the sub-project area,

some Catholics, Protestants, and Buddhists should have their own beliefs compared to workers and

non-religious people, so if workers are not managed, it will cause some conflicts. In addition,

collisions and disputes over materials, property theft of local people and businesses, damage to

materials and equipment, crops ... are the causes of disputes and conflicts, destabilizing local order.

c. Impact assessment: negative impact is medium

329. The arising impacts are assessed as medium due to: i) the demand for workers concentrated at

construction sites is not large, and in a short period of time; ii) The construction site is located

relatively isolated, away from the concentrated residential areas; iii) The contractor has plans to use

some local sources of labor.

5.2.3.11. Labor accidents for workers


330. Operating equipment and machines, performing construction activities on sites and camp

conditions.

b. Impact analysis

331. A number of machinery and equipment will be mobilized on the construction site, so the

operation of machinery and equipment will cause the risk of labor safety for workers. Electric shock

accident may happen when there are electrical leakage or unsafe electrical management on site. In

addition, workers’ health will be affected, there will have many types of illnesses due to unsafe

accommodation conditions, no periodic health care….

c. Impact assessment: negative impact is medium



332. The medium impact of equipment mobilized on site is not super long, super heavy or easy to

operate. However, it is necessary to strictly follow the labor safety measures proposed during the

subproject construction phase to ensure safety for workers and local communities and rapid response

mechanisms when there are risks of labor insecurity

5.2.3.12. Discontinuity of irrigation water due to construction


333. During the construction of items such as: Construction of water intake, dam construction,

flood spillway. Water withdrawal of water in the reservoir for construction is necessary. Depending on

the construction volume of items, the time for water withdrawal is from 1-3 months. And the time of

accumulating water is 1 month. Therefore, in the course of construction, interrupting irrigation water

for agriculture and forestry is inevitable.

334. In addition to the interruption of irrigation water, the cutting of water may cause disputes over

irrigation water sources, disturbing social order and safety locally. Or cause gender inequality because

women are more likely to work in agriculture and they will have to find alternative water sources.

b. Impact analysis

335. The renovation and repair of dams at 8 reservoirs will lead to potential disruption of irrigation

water, thereby affecting agricultural production..

336. Because the technical design of the subproject is the embankment embankment plan, So the

water source is maintained at a minimum to ensure production activities. The construction of sluice

interrupting the flow will be arranged with an alternate flow, so the damage caused by disruption of

irrigation water for agriculture is well controlled.

5.2.3.13. Impact on graves, cultural heritage and public works

337. There are no any tombs built around the existing construction site around the subproject area.

Besides the subproject with a radius of 3 km, there is absolutely no cultural heritage, so the

construction does not affect the graves and surrounding cultural heritages.

338. In the process of soil excavation and embankment, it is possible to detect artifacts, cultural

heritage or graves. In that case, the progress of the project will be affected and the involved parties

must take action. Therefore, it is necessary to have a procedure to handle the object detected in the

construction process of the subproject.

339. During construction, the number of vehicles operating at such a peak time may cause

degradation of inter-village roads and soil roads on the dam surface.

340. Transporting construction materials and machinery can cause subsidence and cracking road.

Construction process should take measures to protect transportation routes.

341. Overall assessment of impacts of detecting graves, cultural heritage and public works: Low



impact and can be controlled

5.2.3.14. Impact on livelihood and business activities by the construction

342. Construction activities may disrupt water supply for production and business activities of

some households. According to the survey, some households are living along the road to the dam,

there are many small traders but this is not their main source of income. However, to minimize and

limit impacts, project owner will work closely with the local authorities to assess the impact level to

have appropriate support. In addition, during the construction process, contractors plan and organize

construction to minimize the impact on these affected households. Local authorities make

compensation and support in accordance with the policies stated in the RAP to ensure not to worsen

the livelihood and business status of AHs.

343. 100% of people said that they were concerned about the environmental impact due to

transportation of soil and construction materials which could make the environment dusty. People also

worry that many migrant workers will break the quiet environment of the countryside and can cause

security problems such as theft. Therefore, it is assessed as average negative impact and can be

managed through appropriate mitigation plans.

344. Overall assessment of construction impact on livelihoods and businesses of households

near the subproject area: Low impact and controllable

5.2.3.15. Impact on gender equality and children

345. The subproject investment will mainly affect the environment during construction, due to

material transport and machinery equipment noise,…In addition, when participating in the

construction, workers moving from other places can also bring diseases and their activities may break

the tradition and local regulations. Women are at high risk of HIV / AIDS infection, traffic safety. Or

during construction if workers are not managed well can happen unwarranted relations with the people

in subproject area causing loss of family happiness leading to gender violence and subsequent bad

consequences. In addition, poor women and women-headed households in the project area are also at

risk of damage to economic assets due to water cut during construction.

346. During construction in 4 reservoirs the dam surfaces are also traffic roads between hamlets or

road to farm. At night, women and children are at risk of accidents caused by the construction site or

poor management of workers can lead to incidents such as teasing or rape. Moreover, gender violence

can also occur during the subproject implementation as there will be a number of female workers.

Roads will be more difficult and dusty in the rainy season, it can affect the psychology of children

who are afraid to go to school and is the cause of children leaving school, so the contractor has plan to

carry out the construction mainly in the dry season

347. In the construction process, active children are always concentrated around the construction

site, which can cause occupational accidents. Especially, the lakes are deep, it is easy to drown for

children. There are also risks if the contractor hires child labor, resulting in a violation of the

Vietnamese labor law. Therefore, there must be a safety policy for children, protection of children's

rights, not allowing children to sell goods or provide services around the lrepairing and upgrading

reservoir areas.

348. According to the survey data of households in the subproject area, for family activities: child /

child care; cleaning the house; cooking / housework is mostly female work. These jobs take a lot of

time for women so they have less time to do other activities such as participating in social activities,

learning to improve themselves and on the other hand, participating in decision making important in

the family: The majority of households agree that two people take part in making big decisions in the

family (purchasing valuable assets, weddings, kinship, village, etc.), accounting for 46.2% of both

sexes key decision making and implementation. However, it should be noted that up to 51.6% of

households where only men are the decision makers and perform large-scale work in the home. This

shows that patriarchal, conservative thinking still exists in many cultures and errors of families here.

Thereby shows us, when there is a sub-project, the WB always supports women are equal and take

part in subproject works, It is also difficult to ensure that women here can participate in the subproject

vbecause they still depend on housework and decision-making power for men is the head of the

household.



5.2.3.16. Negative impacts on ethnic minority people

349. The implementation of the subproject has firstly brought a lot of positive impacts on the lives

of ethnic minorities, in particular, the Muong people. However, during the implementation of the

subproject, especially during the construction process, certain impacts on this community in the 4

subproject communes cannot be avoided. The communes with ethnic minorities participating in the

survey are Xuan Phuoc, Hoa Tan Tay, Ea Bar, Son Dinh, the ethnic minority groups here are mainly

Cham and Khmer people. Especially when constructing and repairing intake water, cutting production

water is mandatory, so the lack of production water in a season affects the lives of people here a lot.

However during construction will try to execute when people finish harvesting agriculture and another

measure that can be used is to embankment of to serve the people.

350. Currently, ethnic minority households have lived in harmony and alternately with Kinh ethnic

households in the subproject area. Due to being in this area for a long time, the typical customs and

practices of the ethnic minorities here are no longer in harmony with the customs of the Kinh ethnic

people, Agricultural cultivation is still the main occupation of ethnic minority households here.

351. Construction of the subproject will require water cutting at intervals of 1-3 months, therefore,

EM households in subproject area may be affected by lack of water for agricultural production.

Besides living with the Kinh, the economic and social access of EM households is still slow, The

problem of understanding about HIV / AIDS is still limited, so the process of gathering workers and

communicating will affect EM people.

352. Overall assessment of the impact of subproject on EM people: Low impact and

controllable

5.2.3.17. Impacts on the ecosystem

353. The subproject activities generate wastes that are likely to affect aquatic ecosystems including:

waste oil, oil-containing wastes, construction wastewater and domestic wastewater.

- Waste oil and oil-containing waste is a kind of hazardous waste. The aquatic ecosystem in the

reservoir bed is not diverse and has few categories, in the reservoir there is no aquaculture and

the aquatic ecosystems downstream of the reservoir are the aquaculture ponds of the people

and the area of the canals is mainly of the Carp (Cyprinus), Drift fish (Cirhina molitorella),

Tench, Tilapia, Snail carp, shrimps and crabs... The consultant has assessed the current status

of aquatic species in the project area in section 4.2.2 of this report. Some construction sites,

where there are many workers (from 30 to 60 people ), domestic wastewater has

concentrations of BOD5, COD and TSS many times higher than Cmax according to QCVN14:

2008 / BTNMT with a coefficient K = 1,2 , calculated for production establishments of less

than 500 people when discharged into type B water source according to QCVN 08: 2008 /

BTNMT. Solid waste components have many biodegradable organic substances (leftovers)

and difficult to decompose (shells, plastic)..

- Solid wastes and domestic wastewater are common wastes and will be collected and treated

according to Decree 59/2007/ND-CP on solid waste management.

- Especially in the construction process, the withdrawal of water for construction of items will

affect aquatic ecosystems in the reservoirs. However, reservoirs have the main purpose is to

ensure the water source for irrigation and to regulate the climate in the surrounding area.

Therefore, the status quo of the reservoirs does not cultivate any aquatic species. At present, in

the lake, there are only types of carp, drifting fish, carp, carp, and mainly tilapia in the lake. In

terms of plants in reservoirs, mainly algae, there are no rare species that need to be preserved.

Therefore, the impacts on aquatic ecosystems in the lakes are low and negligible.

354. The activities of the subproject also affect terrestrial ecosystems such as: solid waste, waste

rock and soil, overflowing stormwater, which affects agricultural and forestry land around the area

subprojects and the destruction of plant ecosystems for construction site cause impact due to cutting

tree…

- Construction of the subproject will generate a quantity of solid waste and waste stone and

waste soil, if not well managed, the dumping of solid waste, soil and stone into the

environment around the subproject or dumping in the wrong location will affect the terrestrial



ecosystem, altering soil quality, or degradation of plants around the subproject.

- In the process of creating the construction site, it is necessary to cut down trees and crops.

However, in the subproject area, most of the surrounding area is productive forest land and

agricultural land. Terrestrial ecosystems are not diverse, with plants such as acacia,

eucalyptus, rice, sugarcane, ... and shrubs or weeds. However, it is necessary to prohibit

workers from cutting down trees outside the clearance area of the subproject. Therefore, the

impact in this process on terrestrial ecosystems is low.

- The types of terrestrial animals around the subproject area are not diverse and few species.

Because the area around the subproject area is mainly production forest land and agricultural

land, the main animals are livestock of people around the subproject such as pigs, chickens,

ducks, geese, buffaloes, cows and goats. ... Therefore, the impact in this process is small. In

the process of preparing the construction site, the subproject will have to cut trees, crops, dig

soil, which will cause loss of habitat for reptiles, amphibians, insects and birds..

- Around the subproject area, there are no rare species that need to be protected.

- Around areas where clearance is carried out to create construction ground, no wild animal

populations inhabitable but mostly the small number of animals raised by the households

surrounding the subproject, therefore, the construction ground clearance does not affect the

habitat of any wild animals.

355. Impact assessment: low negative impacts, controllable

5.2.3.18. Impact on water supply and water usage in downstream

356. Impact on water supply and use water in downstream may occur during construction. Disputes

can occur, or dissatisfaction among households when when interrupting irrigation water supply.

Therefore, the commitment of the households in village meetings is needed and Information should be

disseminated in advance regarding possible situations. However, besides the main water source taken

from irrigation reservoir, households can get water from many water slots as additional source of

irrigation water during 3 months of construction .

357. Water sources for drinking and living are taken from dug wells and drill wells. Therefore,

cutting water for constructing and renovating dams will not affect the water sources of people in the

subproject area.

358. The objective of the subproject is to strengthen the capacity of relevant local authorities to

manage and implement the dam upgrade, encourage participation, enhance knowledge and

understanding of repair management and facilitate the equal cooperation between beneficiary users

and regulatory authority and local government. This will help local people and communities develop

collective water management mechanisms to avoid possible conflicts between stakeholders and

minimize potential short-term and long-term impacts. Specifically, there may be a conflict between the

irrigation company (or local irrigation officer) with people using irrigation water when there is a

discrepancy in the water supply plan. Or, there is a conflict between water users, especially upstream

and downstream households, when there is an uneven, unfair..

5.2.3.19. Evaluate and forecast environmental impacts due to risks and incidents of the

subproject

a. Incidents of labor and traffic accidents

359. Labor accidents can occur at any of the activities during the construction process if it does not

comply with the labor safety regulations.

360. Major causes of labor accidents include:

- Shortcomings in the design of technological measures such as measures to support formwork, anti-

landslide measures which may lead to collapse of the works or labor accident.

- Shortcomings in the construction organization: unreasonable arrangement of labor shift, incorrect

arrangement of work order, using non-standard materials, shortening process of construction ...;

- Technological shortcomings: The machine is not the right type or is not in full quantity. Means or

equipment such as lack of safety, covering, lack of prevention signaling system ...;



- Violating technical safety procedures and norms;

- Causes of Risk: Accidents caused by vehicles, electric accidents ... On rainy days, risk of labor

accidents is high due to slippery ground, electric problems, and land subsidence...

b. Accidents caused by fire and electrical risk

361. Flammable and explosion hazards may occur in the case of transport and storage of fuel, or

due to the lack of safety of the temporary power supply system, resulting in damage to persons and

property during construction. Specific causes can be identified as follows:

- Temporary fuel storage facilities for construction, machinery and equipment (paint, petrol, DO

diesel, FO) are sources of causing fire. When the incident occurs, serious human, economic or

environmental damages may occur;

- When deploying the project, electricity will be used for the construction site, cooking activities.

The human negligence will cause the fire and explosion in the storage of petroleum.

- Accidents caused by leakage, spillage and scattering of construction chemicals: In the construction

process, there are some kinds of admixture and chemicals such as plasticizers and accelerated

intensification of concrete and chemicals, anti-rust paint, expansion additives for cement mortar

....These chemicals and additives are very toxic, they exist in the form of powder or liquid. If they

are leaked or poured into the water and air environment, it will cause serious environmental

pollution. The use of chemicals and additives during the construction can cause fire, burns or labor

accidents if there is no preventive measures.

c. Risks and incidents due to natural disasters

- Risks and incidents caused by natural disasters mainly occur:

- Fire and explosion caused by lightning: In the rainy season, lightning strikes occur on machines

and equipment operating on construction sites, causing the risk of human and property damage..

- Incidents due to storms, thunderstorms, prolonged subsidence, affecting construction structures,

construction progress may be slow and construction quality is not guaranteed.

- In addition to incidents caused by rain, there were also incidents of earthquakes: Moving,

collapsing structures already constructed.

d. Assessment: These incidents do not occur very often but when they occur, the consequences will

be very serious, which can cause great damage to property and people so investors and

construction units need to take measures to prevent and respond to minimize damage.

e. Overall assessment of environmental impacts due to risks and incidents of the project: Average

impact but can be controlled and prevented

5.2.4. Assessment of site-specific impacts

362. There are 6/8 reservoirs with sensitive receptors easily affected by subprojects as shown in the

5.2.5. Evaluating and forecasting of impacts during the operational phase of the subproject

363. Most of the potential impacts during the operational phase are expected to be positive.

Temporary construction effects such as dust, noise and vibration will be stopped during operation.

When being completed, the use of land, landscape, local income and socio-economic tends to be

stable. Improving dam safety and improving irrigation services will promote socio-economic

development and improve livelihoods of downstream communities. Some status will be changed in

comparison with the previous status.

a. Risk of drowning

364. Reservoir can be a place for washing and bathing activities of people. Therefore, there will be

always the risk of drowning if appropriate preventive measures are not taken.

b. Flood due to discharge and dam breaking

365. Due to the characteristics of the subproject, it is to improve dam safety so that the risk of dam

breaking is very low. Emergency discharge of flood can affect downstream communities if it is not

informed in advance; cause damage to assets, crops and people and cause indirect impacts such as

environmental pollution, diseases and loss of income.

c. Repair and maintenance of works

366. These activities can lead to water cut-off in a short time. This would cause direct impact on

the agricultural production and living activities of the downstream people and will indirectly cause

effects such as reduce of income due to time of no cultivation, environmental pollution and disease

due to lack of water. However, this effect is considered as minor because the time of repair and

maintenance is short (only a few weeks).

d. Increase the use of fertilizers and pesticides

367. Although the irrigation area is not increased compared to the original design, but the crop

structure will be change by the amount of irrigation water from the reservoir is kept stable and is not

seepage through the dam body. On the other hand, the area of water shortage will be supplemented to

ensure designed irrigation area therefore, it will increase the amount of fertilizer and pesticides. On the

other hand, according to data on crop structure and fertilizers and pesticides use coefficient in section

4.3.1 of this report, the structure of crop and fertilizer and pesticide use coefficient have been not

changed in the subproject area. However, the area recovered from the original design will increase the

amount of fertilizer and pesticides by 10-15%. As a consequence, the environment and human health

can be affected by toxic chemicals.

368. Besides, according to interviews with farmer associations in the sub-project provinces, the

status of waste treatment from pesticides is as follows: After being used, most of boxes and bottles of

pesticides are thrown directly at the place of use. It is easy to find pesticide bottles and boxes used in

the field, such as along paddies, canals or gardens. Only a small number of households kept bottles for

selling. However, the pesticide bottles and boxes are gathered in unsafe manner in field or around

house. Some bottles are unsafely burned in the field or garden. Most farmers wash pesticide sprayers

in the interior field canal or in the ditches or ponds of the field. Wastewater from washing spraying

tools is poured into the field or into the canal. It can be seen that this habit has put pesticide residue in

water of the canal which is the reason of polluting surface water. Regarding the residual pesticide

mixture, after spraying, the residual mixture is treated by spraying it back to the paddy field or near the

edge of the field or where there is a high level of pest damage. A few people poured residual mixture

directly into the canal. Inadequate treatment of this residual mixture of pesticide will cause the

increase of residual mixture of pesticide in the surface water, leading to impact on aquatic organisms

and on the food chain that affects the farmers themselves.

5.3. Analysis of types of impact

5.3.1. Cumulative impacts

369. The subproject consists of many dams, however the dams are scattered in the territory of the

province. Moreover, the size and nature of subproject activities are small and simple, so that the

implementation of subproject activities is not likely to cause cumulative effects. According to the

survey and exchange with relevant agencies, currently in the area of implementation of construction



items of WB8 sub-project in Phu Yen, at present, there is no other project implemented in the same

area and at the same time, so that cumulative impacts created by other projects are not available.

5.3.2. Direct Impact

370. Implementation of the subproject will cause direct impacts on the environmental and social

conditions in the subproject area. Subproject activities will result in temporary or permanent land loss.

Construction activities will cause direct impact on the quality of the surrounding environment of air,

soil and water due to the generation of waste such as gas and wastewater and the removal of

vegetation.

5.3.3. Indirect impact

371. The temporary and permanent loss of land will cause impacts on the livelihood of affected

persons, reducing or losing of income, leading to change of occupation and social conflicts. Indirect

impacts are also identified through the risk of deterioration of water quality due to soil erosion caused

by vegetation clearing from the construction process. Water pollution due to waste generated from the

construction process can lead to a decline in the composition and number of individuals of aquatic

species. Or soil compaction due to the use of heavy equipment on farmland can lead to a decline in the

number of useful microorganisms in soil due to changes in soil structure. Loss of vegetation will also

lead to loss of habitat for many animal species in the subproject area and increase risk of erosion, and

flooding.

5.3.4. Temporary impact

372. In general, most of the impacts associated with construction activities within the subproject

area are in short-term such as noise, vibration, dust and emissions, and the generation of solid waste

and wastewater. These impacts will no longer exist when construction activities are complet.

5.3.5. Long term impact

349. The permanent loss of productive land will cause long-term impact on the affected persons as

some households are perceived as losing of productive material which leads to change of their

occupation. Environmental incidents such as oil spilling or hazardous chemicals also cause long term

impacts on environment and health status of people because the chemical substance has a long time of

decay and has possibility to penetrate into environment of soil, water and food chain. The risk of labor

accidents also causes long term impacts because the health of labor will be affected or lost.



CHAPTER VI: ALTERNATIVE ANALYSIS

373. With the aim of improving investment efficiency and ensuring safety and minimizing impacts

on the environment and society in downstream areas of the reservoir; scenarios are proposed to select

the design and construction options that are appropriate to the objectives and actual socio-economic

conditions of the 8 reservoirs. Construction activities are mainly reinforcement and repair on the

existing works. Because the design option, selection of technical solutions, technology in the

construction of the work items of the subproject has no difference in the impact on the environment

and society in the subproject area so that the contents of alternative analysis specify the difference

related to environment and society in the scenarios of implementing or not implementing the project.

6.1. Without subproject

374. The works have been constructed and exploited for a long time and seriously downgraded:

375. Dam surface, upstream and downstream slope: Currently the dam face at the reservoirs: Phu

Xuan; Dong Khon; Hon Dinh; Gieng Tien; Hoa Thuan are the homogeneous earth dams and dam crests

have been not reinforced. In the rainy season, it is difficult to monitor and operate the works. Some

wave-breakwalls were broken and sloughing. Most upstream slopes are paved with stone, has been

peeled and landslide upstream slope. The downstream slope of many locations is landslide, trees grow

on the dam slope, there is no drainage system in downstream of dam. Especially in all dams are

absorbent through the foundation and dam body with a large flow; wall of upper and downstream dam

slope subsided, there are cracks across the dam, there is no protection layer for face dam and downstream

slope;

- Assessment: Without the subproject, the status above will continue to occur and the status of

the dam will become more and more serious due to landslides. On the other hand, it can cause

large water loss in the reservoir affecting water supply in downstream.

376. Spillway: 3 reservoirs Dong Tron; Phu Xuan; Gieng Tien, status spillway: After many years

exploiting, most of the spillways have been downgraded, mortar is doted and peeled, seepages is along

the body of spillway, the soil on both sides of the talus is landslide into the spillway. Some reservoirs

have energy dissipitator tanks but are badly damaged, the remaining reservoirs do not have energy

consumption tanks. The spillway have also been degraded, causing dam safety.

- Assessment: If the subproject is not implemented, the current capacity of the spillways will not

be sufficient to meet the drainage requirement if heavy rain and storms occur and a large

amount of water will be gathered into reservoir which will cause the status of dam breaking

and landslides. Especially, spillways with seriously damaged energy dissipitator tanks, it can

cause serious flash floods and affect the life as well as the property of people in downstream

area.

377. Intake: In all 8 reservoirs of the subproject, the intake culvert has been badly damaged at the

entrance and exit, the culvert body is damaged, broken, there is water leakage along the culvert body

toward downstream, cannot use the level water as required.

378. Monitoring system: At present, all of the 8 reservoirs of the sub-project have no monitoring

system so they cannot promote disaster warning efficiency.

379. Management road: Currently of 6/8 reservoirs Management road is either soil roads or

macadam roads which are small and narrow (except 2 reservoirs of Dong Tron and Ea Din1 have

concreted management roads). On the rainy days, it is very difficult to travel and it cannot ensure

traffic condition and management of dam.

380. Management house: Currently 3 reservoirs Hon Dinh, Hoc Ram, Dong Khon have no

managers house. This is inconvenient for the operation and response to dam safety incidents. In case

of occurring dam safety incident, it causes risk to people and their asset in downstream area. On the

other hand, if the routine monitoring and maintenance are not implemented, it will cause damage. The

remaining reservoirs were constructed management house. However, the management house of the

reservoirs have been downgraded and need to be upgraded and repaired.

General assessment:



- The current status of the reservoirs causes constraints on the development plan and

improvement of productivity and economic efficiency in agricultural production; does not

ensure proactive irrigation water; affect the selection of plants and livestock; cannot exploit all

economic value from natural land source.

- When the subprojects are not deployed, the ecosystem of the area around the reservoirs will

stably remain. However, due to the current status of the degraded reservoirs, it causes the

potentiality of breaking dams causing damage to people and structure and breaking ecosystem,

especially in downstream area of reservoirs.

- In recent years, due to the climate change status, floods appear more with heavy rain and

intense intensity which causes high risk of safety due to small reservoir bed. A synchronous

construction solution such as the investment in construction, repair and upgrading of

reservoirs is imperative to ensure the safety of life and property of people in the downstream

area and to serve the requirements of economic development of the locality.

6.2. With sub-project

a. The plan is selected when implementing the subproject:

Soil dam:

- Completing the section in accordance with current technical regulations and standards and

ensuring specific and stable conditions of works:

+ Maintain the status quo of 03/08 reservoirs (Dong Tron, Phu Xuan, Hoa Thuan).

+ Increase the elevation of dam crest, downstream embankment of 01/08 reservoir

(Hoc Ram).

Land mine location: Buy soil of the mines has been licensed to exploit in Phu Yen province

Landfill location: Written agreement with communes on location of landfill

Location of worker camps, material yards: Downstream of the dam and its crest are located within

the dam safety corridor.

Labor flow: The technical works, The contractor's workers should be brought there, However, there

are still 40-50% of local skilled workers and especially women are still employed by the contractor for

the subproject.

Construction machinery: Maximum mobilization for each works and machines must be tested.

b. Analysis of selected options

- Options and technical solutions for the main dam and spillway: Completely reasonable for

the situation and the status of the degraded and waterproofed works. On the other hand, before

constructing the works, the option of treatment of termite for dam body was not selected.

However, when the design unit discovered that there were termites in the dam body, the

termite treatment plan was selected to ensure dam safety after completing. Regarding

spillway, the first option which was not chosen, is to keep the current status of the spillways

and reinforce the repair of existing damaged items. However, this option causes the risk of

dam safety. When there is heavy rain or flood discharge, the large amount of water plus the

small spillway width will create great pressure and endanger the downstream area. The second

option, which was chosen, is expansion of spillway, construction in accordance with the form

of the Labyrinth and Piano to reduce the water pressure and have stilling basin to ensure that

flood discharge does not affect the downstream area.

- Options of construction of intake: The technical design has been designed to ensure the

safety of the dam. However, during the construction of intake and some types of dams, it is

required to cut off water for construction. There are two options as below, where in the option

2 has been selected.

• Option 1: Discharge all water in the reservoir to ensure comprehensive and rapid

construction and save the cost. However, this option will cause significant negative

impact that it is required to discharge a large amount of water in the reservoirs which

will cause flooding and damage to crops in the downstream area. On the other hand,

the large amount of water will cause stagnation and pollution of air environment.

Aquatic animals and aquatic animals will die and drainage of water will cause the lack



of water for agriculture production of the people. Therefore, this option is not

selected.

• Option 2: Construction diversion. Depending on each construction item, the water in

the reservoir will be drained slowly that allows construction of cofferdam to prevent

water for the construction activities. In addition, it still leaves the minimum flow to

serve agricultural production of people. This option ensures that downstream safety is

not affected by immediate flooding and does not pollute the aquatic animals and

plants. Besides, in the crop season of people, there is still water being available for

agriculture and in case of lack of water, people still use water from nearby pond,

reservoirs and stream. This option requires a large amount of embankment soil and

machines. However, the amount of excavated soil is large that can be used for

embankment of cofferdam. Therefore, the option 2 is selected.

- Option of construction road combining with management road: Roads for transportation

of materials: Currently, most of the management routes to the reservoirs are mostly

homogeneous roads and there is only one route to the reservoir, so there is no alternative

option for management road. The upgrading to ensure traveling and operational management

is appropriate. Roads for transporting materials: The selected option is to transport materials

through roads where there are few vehicles traveling and with sufficient loading capacity.

Especially, the transport routes should avoid sensitive areas such as schools, medical station

and cultural center. Therefore, roads for transporting materials from districts’ center have been

selected according to the criteria for avoiding sensitive works as above.

- Location of the borrow pit: There are two options

• Option 1: Coordinate with CPC to identify soil mines in the commune area and ensure

the quality of embankment. However, this option was not selected because: When

conducting soil mining, it is required to get permission from the Provincial People's

Committee and to prepare a separate EIA report for the location of the soil mine. On

the other hand, it is necessary to have the basic measures and environmental

monitoring for soil mines and must be reverted after use. This option is costly and

time consuming.

• Option 2: The plan is selected: Buy soil from regional licensed mines, around the

subproject, there are soil mines to ensure reserves serving the subproject licensed to

operate and there are separate management units and legal responsibility. Therefore

option 2 is convenient and cost-effective for the subproject.

- Location of dumping sites: When conducting survey of the project, the consultant unit

coordinated with the People's Committees of the subproject communes to find, identify and

make minutes of the location of disposal site. The disposal site is required to meet the

following criteria: being far from residential areas, far from water sources, and minimizing the

management of households and avoiding the types of forest land, agricultural land and

residential land. The location of the disposal site must be convenient for waste treatment to

avoid causing environmental pollution. Another option is also selected that the need of people

to use waste soil to level their site is large, so people will ask for waste rock and soil to level

their site. However, this plan needs the consent of the investor and CPC.

- Location of worker camp and material gathering sites: There are two options being

proposed, including: the borrowing of land from the CPC or from the households. This plan is

not feasible because it can lead to disturbance of security and conflict; being far from the

subproject implementation site; restore the borrowed land area. Option 2 is the chosen option:

most of the downstream area and the crest of the dam are under large safety corridors which

are close to the construction site, away from the residential area, do not pollute the

environment and being favorable for transportation of materials. However, it is necessary to

ensure safety due to natural disasters and safety incidents...

- Labor force: The plan of bringing skilled workers from other localities has been taken into

consideration. However, in localities, the labor force is very large, and there are still skilled

laborers who are suitable for the work. On the other hand, local labors can go home for eating



that they can save money and minimize waste to the environment, and minimize local security

conflicts.

381. Construction machine: All types of machine that contractor brings to the site are inspected

and controlled for safety. Works are relatively far from each other, thus it needs to be minimized the

movement of machines from one place to another and not wasted time as well as labor force of the

project. The other proposed option is to rent some local machines to save money and human resource.

However, it is important to ensure that machines will be inspected and contracted between the

contractor and the lessor.



CHAPTER VII: ENVIRONMENTAL AND SOCIAL MANAGEMENT PLAN (ESMP)

7.1. Objectives

382. The ESMP of the subproject is designed for specific purposes as follows:

7.2.1.1. Mitigation measures due to land acquisition and site clearance

383. An ethnic minority resettlement and development plan has been prepared and implemented for

the subproject.

General principles:

384. All households affected by the subproject have assets or reside within the subproject area

Before the end of the tally compensation will be paid. People who lose income and / or livelihood will

be assisted in restoring their livelihoods based on eligibility criteria defined by the subproject with

consultation with AHs. If by the end of the subproject, livelihoods have been proven not to be restored

to the extent that before the subproject, there will be additional support measures.

Rights:

385. Affected households will be entitled to compensation, support and resettlement policies (if

any) in accordance with the regulations of Vietnam and the World Bank under OP 4.12. AHs will not

be considered for compensation or support from the subproject for the area to be recalled after the

announcement date of the counting of tally.

Impact mitigation solutions

386. At the request of the World Bank, the Plan of Land Clearance has been prepared for CSC

subproject. Accordingly, compensation will be made to affected households and organizations due to

land acquisition, and other types of assets on the land. In addition, assistance is also provided to

minimize the impact on livelihoods, source of income and life of the affected people. Ensure that AHs

have life at least equal to the living conditions before the implementation of the works under the

subproject.

387. All costs for land acquisition and clearance activities include: i) compensation for land; ii)

compensation for crops and trees on land; iii) compensation for construction and structures on the



land; iv) costs to support AHs. These costs are in line with the policies of the Government of Vietnam

7.2.1.2. Prevention and minimizing the impact on site preparation works

388. In the preparation phase of the subproject, activities are implemented including clearing

vegetation, clearing the construction site, constructing roads, constructing camps and auxiliary items. ,

construction of houses for construction and sub-project workers, etc. Based on the contents presented

in Chapter V of the report on assessment of environmental and social impacts in this period, the

Preventive measures and minimize the impact included:

- For domestic wastes: The minimum number of workers is 5 people, they may come from this area

which do not cause additional domestic wastes.

- For the removed plants: In order to limit the impacts caused by the existence of plant biomass on

the site, the project should take measures to collect and treat the whole plant biomass immediately

on the construction site. The treatment method includes burning on the spot with the small

quantity, or contracting for transportation and treatment with the unit at the commune level.

- For the amount of waste soil, Landfills, construction road, the investor needs to have agreements

and permission from the local authorities before construction activities start on construction sites.

- For the amount of organic topsoil due preparation activities landfills, the topsoil is rich in organic

at the landfill site, the contractor will retain and shield full, prevent overflowing to revert the

landfill locations after exploitation and use to plant trees in such areas.

7.2.1.3 Landmine clearance and management of geological exploration boreholes

389. Landmine clearance: will be implemented before land acquisition. This work will be done by

specialized demolition units of the Army in the province. Project owners and specialized clearance

units will have to notify local people at least one month before site clearance and must use protective

fences and warning signs to reduce risks for people and pets. The demining unit and the investor will

appoint an officer responsible for instructing the people not to enter the clearance area. Landmine

clearance is conducted in accordance with Circular 146/2007 / TT-MOD of the Ministry of Defense

and Ensuring a safe distance and alerting people in the process of complying with QCV 01: 2012 /

❖ Impact mitigation measures due to water cutting for construction of work items

393. During the construction of works such as: construction of intake, dam and spillway, the drainage of water in the reservoirs for construction is necessary.

Depending on the volume of construction items, the drainage duration is from 1-3 months. And the duration for re-storing water is about one month. Therefore, in



the process of implementing the subproject, the discontinuity of irrigation water for agriculture and forestry is inevitable; however, impacts from the water cutting

for construction of items can be controlled through mitigation measures and the contractor is the unit implementing these measures under the supervision of the

PMU, the construction supervision and local community monitoring committees. Specific mitigation measures are as follows:

- Inform about the construction schedule for locality and people before six months to have plan of using and supplying water for local people and localities.

- Using the method of embankment of retaining dike and diversion for construction of dams and intake. This is the best mitigation measure due to water cutting.

This measure will drain water level in reservoirs to dead water level and embank dikes in the construction area, then it stills conducts diversion of flow in the

reservoir to serve people and local agricultural production.

- It is necessary to pay attention to crop time and time of irrigation demand to determine the reasonable time of construction. It is therefore necessary to refer to

the local authority and reservoir management unit prior to the construction of the subproject.

- In addition, the use of water sources from streams and other water bodies in the area and water from reservoirs is also a means to be used.

❖ Impact mitigation measures due to construction of the subproject on Gender Equality and Children

394. In the process of constructing the subproject, it may affect gender equality, women and children in the project nearby areas and on site, so mitigation

measures are proposed to the contractor under the supervision of the PMU, construction supervision consultant and community supervision board in localities.

Specific mitigation measures are as follows:

- Continue to promote communication on raising awareness of gender equality, HIV / AIDS to all levels of people and the women themselves. Develop and

implement communication activities, models of gender equality in suitability with the subproject area. At the construction site, there should be propaganda

materials on gender, HIV / AIDS

- Management of labor flow, especially women. Cooperate with local authorities to have good management measures. Enhance the responsibility of the local

government and the contractor, especially promote the role of the heads of agencies, localities, consultancy supervision and site manager in the implementation

of the objectives of gender equality; arranging and assigning tasks to women.

- In the process of construction, there should be measures to prevent prostitution and sexual abuse against women and children.

- The construction site should be installed signs and lights at night to ensure that women and children are not impacted when going through the site at night.

- Children are prohibited from entering the construction site. Fences and hazard signs at the construction site and dangerous areas at the dam should be provided.

- Do not employ child laborers under 16 years old. Need to coordinate with localities to well manage labor flow.

7.2.3. Mitigation measures for site-specific impacts

395. In addition to the general mitigation measures mentioned above, during the implementation of the 6/8 reservoirs in Phu Yen province, there are specific

impacts on sensitive areas scattered on the construction sites. After consultation with local authorities and communities, specific solutions and implementation are

presented in the following table.

and monthly information brochures will be announced. The announcements will be made on local

media to disseminate about coming activities.

426. Every complaint and corresponding action implemented by the contractor will be recorded in

safeguard monitoring report of the subproject. Complaints and requirements on compensation will be

submitted as follows:

- By verbal: directly to CSC and/or safeguard officials or representative of contractor in the site

office;

- By writing: handing over or sending complaint letter to the designated address;

- By phone, fax, email: send to CSC, employee or safeguard representative of the contractor.

427. When receiving a complaint, CSC, staffs or safeguard representative of the contractor will

register the complaint in the complaint file and maintain diary of the events related to the complaint

until the complaint is resolved. Immediately upon receipt, four copies of the complaint will be

prepared. The original copy will be kept on file, one copy will be used by the contractor's safeguard

staff, one copy will be sent to the CSC and the fourth copy will be sent to the PMU within 24 hours

from the time of receiving complaint letter.

428. Recorded information on the complaint includes:

- Date and hour of complaint;

- Name and address of the complainant;

- Brief of complaint;

- Actions taken to resolve the complaint, including person contacting and finding at each step in

the complaint handling process;

- Date and time when the complainant is allowed to contact to resolve;

- Final decision on the complaint letter;

- Date, time and method that the complainant is informed;

- Signature of the complainant when his/her complaint is resolved.

429. Minor complaint will be processed within one week. Within two weeks (and every week

thereafter), a written response will be sent to the complainant (by hand, post, fax, e-mail) indicating

procedures which are conducted until now.

430. The main objective is to solve the problem as quickly as possible by the simplest means,

involving as few people as possible, and at the lowest level as possible. Only if a problem cannot be

resolved at the simplest level and / or within 15 days, other functional agencies will be involved. Such

situations may arise, for example, when the amount paid cannot be resolved for the damage, or the

cause of the damage is determined.

7.5.3. Grievance redressing mechanism of WB

431. Community and individual believe that if they are adversely affected by a project funded by



World Bank (WB), they can send their complaint to the grievance redressing mechanism at subproject

level or complaint redressing board of WB. This organization ensures that recorded complaint will be

quickly considered to resolve issues related to the subproject. Subproject affected community and

individual can send their complaint to external monitoring board of WB to determine if bad effect is

happened or not due to not complying with policies and procedures of the WB. Complaints are

considered in any time if the complaints are paid attention and the PMU will be responsible for

responding. In order to know information on how to send complaint to the grievance redressing

service of WB, please refer to: www.worldbank.org/grs. In order to know information on the way to

send complaint letter to Inspection Board of WB, please refer to: www.inspectionpanel.org.

7.6. ESMP Implementation plan

7.6.1. ESMP Implementation Plan of the Contractor

432. Upon contract signing, based on the ESMP of approved subproject and construction method,

the construction plan has been approved by monitoring consultant and the PMU, the Contractor shall

prepare Contractor’s ESMP (C -ESMP) for the package and submit to monitoring consultant for

review and approval.

- After the C-ESMP has been approved by monitoring consultant, the contractor shall take

measures to mitigate environmental and social impacts on site.

- The C-ESMP will be published at worker camps and site offices to disseminate information on

mitigation measures to workers.

- Make public information board at the entrance of construction site with available addresses,

representatives, phone numbers of the concerned parties for monitoring by local community

and contact when needed.

- Assign staff in charge of environment and safety, training and providing protective equipment,

periodical health checks for workers;

- Survey and check on-site environmental status, report to monitoring consultant if there are any

significant differences compared to base environment.

- Sign contracts with authorized units to treat domestic wastes, hazardous waste, and supply

clean water.

- Manage workers and construction equipment and provide new certificates/permits in case of

expiration.

- Implement ESMP and update, and submit to construction supervision consultant for approval

if any changes before applying.

- Coordinate with PMB and construction supervision consultant to redress complaints of local

people on environmental and safety issue of the package in a timely manner.

- Monthly report on ESMP implementation of the package.

7.6.2. Subproject commencement and personnel

433. The contractor's staff in charge of environment protection must be an environmental engineer

or one with related expertise and must have an occupational health and safety certificate and work full-

time on site.

434. Provide training on occupational health and safety and regular health checks for workers.

7.7. Capacity development and training plan

7.7.1. Training on safety policies

435. Phu Yen DARD has implemented projects funded by the World Bank, so there is a certain

understanding of the WB's safeguard policy requirements. The PMU established under Phu Yen

DARD for the implementation of this sub-project has appointed a staff to be responsible for

implementing the environmental safeguards of the subproject. However, this officer has not yet

grasped the requirements of the Bank's safeguard policy. As a result, the environmental officer has

participated in World Bank safety training courses organized by the World Bank and the CPMU at the

http://www.worldbank.org/grs

http://www.inspectionpanel.org/



early stage of project implementation. Training and capacity development are annually carried out

through technical assistance activities of World Bank safeguard policy officers focusing on new

safeguard policy requirements. As new environment, society, health and safety requirements are set

out in the standard bidding documents, training in the environment, society, health and safety

requirements will be provided by the World Bank's Safeguard Policy Officer to the environmental and

social safeguard staff of the PPMU, the construction supervision consultant, the environmental and

social safeguard staff of the contractor as soon as they are mobilized and the PPMU will be

responsible for organizing the training in coordination with World Bank safeguard officers.

436. Such training courses will be held at the early stage of the subproject implementation process

to ensure that the ESMP is properly integrated into the bidding document (and subsequently the

contract). Technical assistance should be provided by experienced and skillful staff of construction

supervision consultants, and implemented in accordance with the terms of reference including specific

references to the development of the requirements of the investor for the standard tender. In addition,

the types of training courses will be implemented as follows.

7.7.2. Occupational health and safety training

437. Provisions will be made to provide occupational safety and health training for all new

employees to ensure they are informed of the basic regulations in the site on personal protection and

prevention of colleagues from injuries.

438. Training will include basic hazard perception, specific hazards, safe work practices, and

emergency procedures for fire, evacuation and natural disasters in appropriate manner. Any used

particular hazard or color code will be considered in a thoughtful way as a part of the orientation

training..

7.7.3. Orientation of visitors

439. If visitors are allowed access to areas with hazardous conditions or substances, orientation and

control program for visitors will be established to ensure that visitors do not go into dangerous areas

without being accompanied.

7.7.4. Training for new contractors and workers

440. The PPMU will ensure that workers and contractors, before starting new work, will receive

adequate training and information so that they can understand the hazards of work and protect

themselves from the hazards. Training will include:

441. Understand about materials, equipment and tools

- Understand about the hazards in operation and how to control them

- Potential risks to health

- Warnings to prevent exposure

- Sanitary requirements

- Wear and use clothing and protective equipment

- Appropriate response to extreme operating conditions, accidents and incidents

7.7.5. Basic training on occupational health and safety

442. A basic training program and intensive courses will be implemented as needed to ensure that

workers are oriented towards the specific hazards of separated work tasks. Training will generally be

provided to managers, supervisors, workers, and occasional visitors to risk and hazardous areas.

443. Workers in charge of first aid and rescue will receive special training not to intentionally

exacerbate the exposure and health hazards to themselves and their colleagues. Training will include

the risk of transmitting the disease through blood through contact with tissue and body fluids.

444. Through appropriate contractual terms and monitoring, the PPMU will ensure that service

providers as well as contractual labors and subcontractors are adequately trained before

commencement of work.

445. The PPMU will be responsible for coordinating with construction supervision consultant and



officer in charge of environment of contractor to organize training courses above.

7.8. Environmental quality monitoring plan

7.8.1. The compliance monitoring

446. Environmental compliance monitoring is carried out to assess the compliance with operational

standards and proposed national environmental norm and standards. The main purpose of the

Environmental Compliance Monitoring is to ensure that all proposed mitigation measures are

complied with by contractors during the construction, to early identify arising environmental issues

and to timely propose additional mitigation measures.

- The PPMU and the CSC will monitor the compliance of the standards. The PPMU and the

CSC will monitor the Contractors’ activities in accordance with the agreed mitigation

measures. The results are summarized in the monthly reports.

- Local authorities in 13 communes and communities in 8 reservoirs will carry out monitoring

tasks according to Government regulations, Law on Environmental Protection in 2014 and

Decree 80/2005 / ND-CP - Regulation regulations on community investment monitoring.

- In addition, the Contractors’ environmental safety staff will be responsible for day-to-day

monitoring of labor safety and environmental sanitation and reporting to the CSC.

- The detailed monitoring plans will be prepared during the detailed design phase. Expenditures

for the monitoring program will be included in the cost of the CESMP implementation.

7.8.2. Monitoring of environment quality

(a) Periodic monitoring

447. Ambient environmental quality monitoring program such as air, soil and water quality

provides information that can be used to assess the effectiveness of pollution management strategies.

A systematic planning process is recommended to ensure that the data collected are adequate for their

intended purposes (and to avoid collecting unnecessary data). This process, sometimes referred to as a

data quality objectives process, defines the purpose of collecting the data, the decisions to be made

based on the data and the consequences of making an incorrect decision, the time and geographic

boundaries, and the quality of data needed to make a correct decision. The ambient environmental

quality monitoring program shall consider the following elements:

- Monitoring parameters: The monitoring parameters selected should reflect the pollutants of

concern associated with subproject processes.

- Baseline calculations: Before the subproject is developed, baseline ambient environmental

quality monitoring at and in the vicinity of the site should be undertaken to assess background

levels of key pollutants, in order to differentiate between existing ambient conditions and

subproject-related impacts.

- Monitoring type and frequency: Data on ambient environmental quality generated through the

monitoring program shall be representative of the pollutants emitted by the subproject over

time. Monitoring frequency and duration may also range from continuous to less frequent,

monthly, quarterly or yearly tests.

- Monitoring locations: Ambient environmental quality monitoring may consist of off-site or

fence line monitoring either by the subproject owner, DONRE, or by collaboration between

both. The location of monitoring stations should be established based on the results of

scientific methods and mathematical models to estimate potential impact to the receptors from

an emissions source taking into consideration such aspects as the location of potentially

affected communities.

- Sampling and analysis methods: Monitoring programs should apply national or international

methods for sample collection and analysis, such as those published by the International

Organization for Standardization (ISO). Sampling shall be conducted by, or under, the

supervision of trained individuals. Analysis shall be conducted by entities permissible or

certified for this purpose. Sampling and analysis Quality Assurance / Quality Control

(QA/QC) plans shall be applied and documented to ensure that data quality is adequate for the



intended data use (e.g., method detection limits are below levels of concern). Monitoring

reports should include QA/QC documentation.

448. Noise monitoring may be carried out for the purposes of establishing the existing ambient

noise levels in the area of the proposed subproject, or for verifying operational phase noise levels.

Noise monitoring programs should be designed and conducted by trained specialists. Typical

monitoring periods should be sufficient for statistical analysis and may last 48 hours with the use of

noise monitors that should be capable of logging data continuously over this time period, or hourly, or

more frequently, as appropriate (or else cover differing time periods within several days, including

weekday and weekend workdays). The type of acoustic indices recorded depends on the type of noise

being monitored, as established by a noise expert. Monitors should be located approximately 1.5 m

above the ground and no closer than 3 m to any reflecting surface (e.g., wall). In general, the noise

level limit is represented by the background or ambient noise levels that would be present in the

absence of noise source(s) under investigation.

449. Monitoring frequency and parameters: The parameters, location and frequency of monitoring

the quality of environmental components are summarized in the following table according to Circular

24/2017 / TT-BTNMT dated September 1, 2017 and according to the instructions of the project's

Environmental and Social Management Framework.

(b) Incident monitoring

450. The purpose of this monitoring is to assess the level of pollution to land and watercourse due

to accidental discharge such as discharge of wastewater and waste oil into nearby watercourse and

land and make a timely decision on pollution control which would help reduce environmental risks.

451. An incident monitoring plan will be developed by CSC at the early stage of subproject

implementation and submitted to PPMU for approval. This plan will identify the potential

environmental risks due to accidental discharge of wastes such as wastewater and waste oil into

nearby watercourse and land. The plan also defines manners to conduct this monitoring, such as

competent personnel, equipment, monitoring locations and parameters, analysis method, dedicated

laboratory, and cost estimates.

7.8.3. Dam safety monitoring

Once the water is accumulated and the dams start operating, the dam owners are responsible for

monitoring the dam safety. This task is done by qualified independent specialists who are not involved

in the investigation, design, construction or operation of the dams. After the dams are in normal

operation, the regular inspection stages take place, including safety inspection of the dams before and

after annual flood season in accordance with Government Decree No. 114/2018/ND-CP on Dam

Safety Management.

7.9. Estimated cost

452. Cost ESMP program implementation will include: i) costs of implementing mitigation

measures on construction sites, This cost is mainly from the contractor's activities; ii) cost of

compliance monitoring, This cost will be included in the contract with the construction supervision

consultant, operational costs, management of PMU; iii) cost of implementing quality monitoring of

environmental components; and iv) Training and capacity building costs. The total ESMP

implementation cost is estimated in the following table (Detailed costs for each item are shown in

Appendices 8 and 9 of this report).

Table 95: Estimated costs for ESMP

No. Cost item Unit Amount

1 Costs for environmental monitoring VND 685,115,631.2

2 Training costs to strengthen capacity VND 102,000,000

3 Costs for environmental treatment works VND 226,000,000

4 IPM program costs VND 82,250,000

5 Contingency (10%) VND 109,536,563,12

6 Total VND 1,204,902,194.32

453. The community involvement in the ESIA implementation is voluntary for the benefit of the

community and people themselves. Therefore, people participating in the CESMP monitoring will not

be paid. However in order to encourage the community participation, the cost of materials and tools

should be allocated to the monitoring activities to support selected community members to participate

in the monitoring. According to Decision No.80/2005/QDTTg dated 18/4/2005 by the Prime Minister

on the Regulation on Investment Community Supervision and the Joint Circular guiding the

implementation of Decision No.80/2005/QD-TTg: "The cost of investment community supervision in

the communes/wards is included in the estimated cost of the budget of the Fatherland Front at the

commune level and deducted from the commune/district budget and financial support for

dissemination, training courses, guidelines, preliminary and final reports. the provincial and district

levels will reimburse from the cost estimate of the Front Fatherland at the provincial/district levels,

which is deducted from the provincial budget”.

CHAPTER VIII: COMMUNITY CONSULTATION AND INFORMATION DISCLOSURE

8.1. Purpose and method

455. In the process of environmental and social impact assessment, Public consultation and

information disclosure are conducted to ensure consensus of the local government, local non-

governmental organizations and affected communities in the subproject area. Community participation

is one of the basic conditions to ensure the support of the local government and community for the

project and to bring opinions and feedback into the report. Through community consultation, adverse

environmental and social impacts have not been identified and mitigation measures can be recorded

and included in the environmental and social impact assessment report. In fact, if the community

participates early in the project preparation process, the relationship between the community and the

project staff becomes closer. On that basis, the community can contribute valuable proposals to the

subproject.

8.1.1. Purpose of community consultation

456. The consultation with local authorities and affected people in the subproject area at the stage

of preparation and implementation of environmental management plan, Environment and Social

Impact Assessment Reports will provide necessary information to better understand the Subproject,

impacts of the implementation, and possible preventive and mitigation measures to the community and

the surrounding environment, specifically:

- Clarify the issues discussed at the beginning of the Subproject;

- Notify benefits to be gained when the Subproject is implemented;

- Point out responsibilities and awareness of the parties, beneficiary people in the subproject

area during the implementation;

- Encourage the community participation in identifying environmental impacts of the

Subproject.

- Gather information about the needs and responses of local people and local authorities

regarding the subproject construction and proposals to mitigate its environmental impacts or to

consider adjustments during the technical design.

- The World Bank's policy (OP/BP 4.01) on Environmental Assessment requires that affected

groups and local non-governmental organizations must receive notification and consultation

during the preparation of the social and environmental impact assessment.

457. The community consultation during the preparation of the ESIA report of Vinh Phuc Dam

Rehabilittion and Safety Improvement Subproject meets the World Bank's safeguard requirements and

the requirements of Decree No.18/2015/ND-CP dated 14/02/2015 of the Government and Circular

No.27/2015/TT-BTNMT dated 29/05/2015 of the Ministry of Natural Resources and Environment on

strategic environmental assessment, environment impact assessmentand environmental protection

plan.

458. The community consultation provides opportunities for affected people to participate in all

project implementation stages. Feedback from the consultations will be considered and incorporated

into the design of construction measures and mitigation measures of the Subproject. The consultation

will be conducted during the implementation process as a necessary condition to address arising issues

in the subproject implementation such as environmental and social impacts. The community

consultation includes the following groups:

• Representatives of villages/villages which may be affected;

• Representatives of affected households, communities living near the construction site which

may be affected;

• Representatives of People's Committees at all levels;

• Representatives of mass organizations, Women's Unions, Farmers’ Unions …

8.1.2. Principles of community consultation



459. Facilitate the participation of affected people and local authorities in the subproject area as

soon as possible;

460. Public consultation has conducted twice:

- First time: Shortly after the environmental screening is completed and before the TOR for the

ESIA is finalized.

- Second time: once the draft ESIA report is prepared.

461. Different methods and techniques are applied in the community consultations, consultations

with affected peoplein the subproject area, including:

- Community meetings

- Household surveys

462. Focus group discussions, field monitoring and interviews with key informants: The use of

these methods and techniques is intended to increase the reliability and validity of feedbacks from the

stakeholders, particularly affected people and ensure that (i) affected people get full information about

the Subproject; and (ii) all affected people are involved in the process of free consultation, prior

notification and full information during the preparation and implementation process

8.2. Consultation process

463. Phu Yen Dam Rehabilitation and Safety Improvement Subproject, according to the World

Bank’s policies (OP/BP 4.01) on environmental impact assessment, requires 02 times of community

consultations. The Environmental Consultant Unit has worked closely with the PPMU, local

authorities and communities in the affected area to conduct community consultation to meet the WB

requirements.

464. According to the preliminary design report of Phu Yen Dam Repairing and Improvement Sub-

project, including 8 reservoirs scattered in 7 communes of 6 districts. Prior to the consultations in each

commune and residential area, the PPMU organized joint meetings in the province and districts to

introduce and collect comments from DARD, DOC, DONRE, DPI, ... and the specialized departments

of Song Lo, Lap Thach, Tam Dao, and Phuc Yen about the Subproject.

465. At the consultation meeting in each commune, the Consultant introduced an overview of the

- The reservoir was built in 1986 and it was repaired in 2001 but

it still does not ensure the safety of the reservoir. Therefore, the

subproject brings huge benefits to the locality.

- It is recommended to adjust the upstream regulating sewer

design plan instead of downstream regulation; downstream of

the flood discharge spillway, there is one section that has not

been solidified, so it should be added.

CONCLUSIONS AND RECOMMENDATIONS

Conclusion

- (i). The subproject belongs to Category B according to the World Bank's environmental

safeguard policy, and is not located in the environmentally sensitive area and do not violate

any "inappropriate" criteria of the World Bank;

- (ii). The report has identified and adequately assessed the potential negative impacts in all

three phases of preparation, construction and operation. Simultaneously, mitigation measures,

in consultation with authorities and affected people, including vulnerable persons, have been

identified;

- (iii). When being implemented, the subproject of dam rehabilitation and safety improvement,

WB8 in Phu Yen province may cause negative effects during the construction phase.

However, because the scale of the construction items is not large and the effects occur in a

short time and the scope is limited in small areas, feasible and suitable mitigation measures

have been proposed proportionate to natural conditions, social and economic conditions,

management and construction conditions of the subproject.

- (iiii). The social and environmental management plan is established to monitor impacts which

helps project management levels and local authority frequently update the process of

implementing work items of the subproject; the monitoring system prepared and approved by

WB will be applied for the implementation of the subproject. The construction supervision

consultant frequently checks and prepare monthly report to submit to the PPMU. This report

will be separated from the environmental compliance report of the contractor. PPMU will

prepare semi-annual monitoring report basing on the reports prepared by CSC and contractor

to submit to CPMU.

Recommendations

- Basing on the findings of environmental impact assessment and the social-environmental

management plan outlined in this document, it is recommended that:

o The mitigation measures mentioned in the Environmental and Social Management

Plan will be established as an integral part of the request for proposal. The contractor

will separate the workload and set the total cost for the implementation of the

mitigation measures. The cost is considered as implementation cost of environmental

safeguard policy and will be paid when the mitigation measures are committed to

undertake by the contractor effectively.

o Basing on the Environmental and Social Impact Assessment report, the safeguard

policy consultant and the PMU recommend the competent authority and the World

Bank to appraise and approve the ESIA report of the Phu Yen WB8 sub-project to be

as the basis for implementing the next steps and to ensure the implementation

progress of the sub-project.
