2. The subproject items

Soil dams: 16 main dams and 5 supporting dams with total length of 1,299m, homogeneous

structure.

Water-intake culvert: Specification D = 250 - 600. Culvert constructions from stone or

concrete, underground structure with pressurized openings.

Spillway: With the exception of Tu Do, Khe Hop, Khe Hoai, Hang Luon và Reservoir Khe

Ngang which have soil-based structures, the other spillways are constructed from stone or

concrete.

3. Present condition

All reservoirs were built long time ago, from 1976 to 1990. For years of operation, earth dams

have been seriously degraded, dams’ body and foundation was leaking; upstream roof slipped;

many bushes and downstream slopes, much permeable to marsh; damaged sewer valve, valve

struss, many leakages. Flood spillway has a narrow aperture, and was much eroded. The

subproject does not ensure safety and flood drainage capacity. Some damaged locations on

the dam body have been reinforced with concrete and plastic. Some parts of the dam crest

have been peeled and subsided. The downstream dam has deteriorated. The dam face has not

been reinforced, subsided, dropped along the dam body. Material paving upstream of the dam

slope is deviated by waves. Upstream and downstream dams with slippery current and

subsidence. Downstream slope is eroded by rainwater due to lack of drainage system.

4. Description of subproject activities:

The proposed activities of the subproject include (i) Stabilizing dam crest (main and auxiliary

dams) with concrete; widening the dam surface, upgrading the upper and downstream roof,

hardening the dam face; Arrangement of downstream drainage ditches, and Installation of

equipment to monitor permeability. The total length of upgraded dams is 1,299 m of 16 main

dams and 5 auxiliary dams of 16 reservoirs; (ii) Repairing or constructing new intake culverts

to ensure stable supply of irrigation water for downstream areas, particularly for water intake

for Khe Vai, Roong Den, Khe Hoai, Khe Ho, hang luon, Khe Chinh and Chop Du. , Khe

Ngang is preserved. In addition to the water intake of Don An reservoir and Tu Do lake, the

valve house is repaired and the pipeline valve is replaced, in the remaining 6 lakes, all new

culverts are built with the form of D300 circular sewer with reinforced concrete structure; (iii)

New flood spillway construction, expansion of spillway surface, solidification of reinforced

4

concrete overflow routes (iv) Repair and upgrade 16 construction roads and management

roads with a total length of 11.85 km; (v) New construction of 16 reservoirs. The number of

workers mobilized to the maximum during peak hours at all construction sites is 1,714 people;

The maximum equipment and machinery used in the construction is 178 units, including

bulldozers, excavators, mixers, concrete compactors, generators and water pumps ... The

subproject is designed and follows the dam safety policy (OP / BP 4.37) of the World Bank

and Vietnam's national standards.

5. Prepare 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 the WB, while

ensuring compliance with the current provisions of Vietnamese law. 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 study before the implementation of

subproject activities. Early identification and characterization of the positive and negative

environmental and social impacts that enable the community and government to assess the

environmental and social impacts of the subproject propose conditions that need 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. Based

on the environmental and social screening implemented, sub-projects of category B are

environmental and social according to the World Bank's classification system. Under the OP /

BP policy 4.37 (safety of dams), the subproject includes both large and small dams so that the

subproject will be prepared with Dam Safety Report (dam safety report). Environmental and

Social Safeguards reports such as Resettlement Action Plan, Social Impact Assessment,

Environmental Impact Assessment, and Environmental and Social Impact Assessment were

also prepared. The subproject is not located within or adjacent to any sensitive areas,

important natural habitats, or important cultural and historical areas.

According to environmental and social screening results, the subproject is classified as

Category B and triggers the following safeguard policies: Environmental Assessment (OP /

BP 4.01), Pest Management (OP 4.09), Involuntary Resettlement (OP / BP 4.12), Indigenous

Peoples (OP / BP 4.10) and Safety of Dams (OP / BP 4.37).

6. Potential Environmental and Social impacts and mitigation measures

Positive impacts: In general, the subproject will bring significant long-term benefits to the

community, especially a stable supply of irrigation water for growing areas. The safety of

dams and reservoirs will be improved due to the restoration of dams and spillways and the

safety of downstream residents. The management of the dam will be more convenient because

the management routes will be upgraded.

Negative impact: Preparation phase: Loss of land and crops - Implementation of the

subproject will directly affect 86,486 m2 of 38 households and 14 commune / ward People's

Committees, of which: (i) Area Affected agricultural land area is: 460 m2; (ii) Affected public

land area: 18,444 m2 belongs to the land of 6 commune People's Committees, including

mainly production forest land, land in the dam protection corridor and (iii) Production forest

land area Affected area: 67,582 m2. In addition, in the process of implementing the

construction items of the subproject, it will temporarily affect the trees of 9 farming

households on public land managed by the People's Committees of communes. There will be

9,980 acacia trees in total; 50 eucalyptus trees, 730 bamboo trees, 3,245 Cinnamon trees, 170

fruit trees, and about 3,220 m2 of tea trees are affected by the project.

5

Construction phase: General impact due to construction activities related to generation of

dust, noise, vibration, waste and wastewater, increased traffic flow and social impacts due to

concentrated and impacted labor In relation to incidents, accidents can affect the health of

local people and the environment. In addition, the specific impacts of the area are

interruptions in irrigation water supply due to lower water levels in reservoirs for construction

(low and remedial levels), dust and noise affecting households and families living next to

roads.

The subproject is not expected to cause significant adverse impacts on the environment and

residential communities where construction works. Negative impacts are expected to be low

to moderate.

Operation phase: Negative impacts during the operation phase of the subproject will be long-

term impacts such as the risk of emergency flood discharge during the flood season without

informing the people in time to affect the area. downstream; interruption of irrigation water

supply due to lower water level for repair and maintenance (low level). Environmental

pollution due to production development - the area of agricultural production will increase by

109 hectares of winter-spring rice crop (up from 660 hectares to 769 hectares) and increase

120 hectares of summer-autumn rice (increasing from 612 hectares to 732 hectares). When

the irrigated area is expanded, the amount of agrochemicals will increase and increase the risk

of soil and water pollution in the area. Integrated pest management will be prepared to

provide mitigation tools for this impact.

7. Mitigation measures:

Pre-construction phase and construction phase: Land acquisition will be minimized through

implementation of the resettlement action plan (RAP). The total estimated cost of

compensation for the items affected by the project is VND 1,516,820,000 (equivalent to USD

65,949). Construction-related impacts will be minimized through the application of mitigation

measures proposed in the ECOP, ESMP and site-specific mitigation measures. Operation

phase: The Emergency Preparation Plan (EPP) will be prepared to prevent the risk of

emergency flooding. The monitoring should be carried out regularly by the management unit

to ensure that the damage will be corrected in a timely manner. Integrated pest management

will be prepared to provide impact mitigation tools related to increased pesticide use.

8. Institutional arrangements

CPMU recruits and hires an independent monitoring consultant, advises and assists the project

in carrying out independent monitoring and regular support on project activities. This unit will

assess safety policy compliance and implementation of safety policy tools in actual

construction. In particular, there is an Environmental Management Plan / Practical

Environmental Code (ECOP), Resettlement Policy Framework / Resettlement Action Plan,

Ethnic Minority Development Plan and Gender Action Plan.

For the subproject, PPMU is responsible for implementing and monitoring the

implementation of the Environmental and Social Management Plan, ensuring bidding

documents and contracts including contractor's environmental agreements on compliance. .

The contractor will implement construction activities and comply with the agreed

environmental agreements in the contract. The contractor's environmental and social

management plan (CESMP) is reviewed and approved by PPMU and sent to relevant units

and disclosed to the community in accordance with Vietnamese law prior to commencement

of construction. Early construction. The PMU and the consultant will monitor compliance

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

compliance will be closely monitored by the Department of Natural Resources and

Environment of Yen Bai Province, local authorities and people.

9. Capacity building

During the implementation process, PPMU receives support from CPMU on implementing

the World Bank's safeguard policy. PPMU staff has been trained by CPMU in collaboration

with World Bank experts on guidance on the project's safeguard policy issues, including OP

4.01 (Environmental Assessment), General Guidelines Environment, Health and Safety (EHS)

of IFC, OP 4.04 (Natural Habitats), OP 4.10 (Indigenous Peoples) and OP4.12 (Involuntary

Resettlement) ... During implementation, training and training on environmental safeguard

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

out regularly to update them on new safeguad policy requirements and relevant information.

For PPMU, during the implementation of the subproject, the subproject will receive the

regular support from CPMU's independent consultancy and technical assistance on the

management of dam safety risk issues and supervision of implementation of the ESMP.

10. Estimated cost of ESMP implementation

The total cost of implementing social and environmental management plans is VND

884,046,000.

11. Grievance redress mechanism (GRM)

Complaints related to the subproject will be resolved by negotiating with the people.

Complaints will be negotiated by the parties at all three stages (Commune, District and

Provincial People's Committees) before being submitted to the court in accordance with the

2011 Complaints Law. PPMU will pay the full cost of administration for legal issues

regarding the reception of complaints because this cost is included in the subproject budget.

12. Community consultation

The consultant and the project owner organized two community consultations, the first was

conducted on November 13-30, 2017 at the office of the commune People's Committee in the

project area. Participants include representatives of local authorities and mass organizations,

representatives of affected households in the subproject area to share information on the

subproject and its environmental and social impacts. The total number of participants is 603,

of which women are 19.5%. The second time, the consultation meetings on mitigation

measures have been implemented from December 20 to 31, 2017 at the offices of the People's

Committees of communes with a total of 201 participants (31.8% of female participants).

Participants are the commune People's Committee, village branch secretary, head / deputy

head of village, Women's Union, Veterans' Association, Farmer's Association; The Fatherland

Front Committee, the project management unit and the affected households benefit from the

subproject activities. Consultation meetings were held to seek consensus on the

implementation of the subproject, and to identify the scope and the affected people, to inform

about the negative impacts of the subproject on Environmental and social mitigation

measures. The local community supports the proposed sub-project (with 100% delegates).

CHAPTER I. OVERVIEW

1.1 General information

The project is designed based on a framework approach to help strengthen the Government's

system of dam safety with a flexible, transparent and favorable mechanism. The number of

dams funded by the project is not fixed, but the initial list of 450 dams has been prioritized

based on the risk assessment using the risk index developed during project preparation and

cumulative costs. Expected design in the source range available. The project will allow the

Government to have additional financial resources to expand the current program to repair

and upgrade 50 dams a year. While not evenly distributed between 34 provinces, 450 dams

are repaired over a 6-year period, which means an average of 75 dams per year, or about two

dams per province each year during implementation.

The project offers the optimal combination of structural and non-structural measures designed

to enhance dam safety. Structural measures include repairing buildings and upgrading safety

structures of existing dams and ancillary facilities, including measuring equipment and related

dam safety planning tools. Building repair accounts for the majority of IDA funding (> 80%).

Non-structural interventions have been proposed to support a wide range of institutional and

legal measures, as well as pilot specific basin-level measures. These basin-level measures aim

to improve data collection facilities, inter-agency information management and coordination

of lake and dam operations in basin management. The project will also help improve

institutional coordination mechanisms as an integral part of these measures to improve dam

safety in terms of operation and support the regulatory environment and tool documents to

guide develop and manage irrigation infrastructure later.

The project is expected to include 03 main components.

Component 1: Dam safety rehabilitation

This component is managed by the Ministry of Agriculture and Rural Development and the

provinces with the aim of improving the safety of irrigation dams through rehabilitation

activities. The project uses two different methods to restore small dams managed by

communities and large dams. The difference between the two methods relates to the type of

work, the relevant legal framework, institution, implementation organization, sustainable

operation and maintenance. Activities of this component include: (i) detailed technical design,

safety policies, quality monitoring and control of rehabilitation and compliance with safety

policies for priority dams fairy and related works; (ii) renovation of buildings, including

construction works, hydro-mechanical engineering, installation of hydrological equipment

and safety monitoring systems; (iii) develop operation and maintenance plans, and emergency

response plans; and (iv) assess flood discharge capacity of large dams to ensure flood

discharge capacity. Funding for this component will be used for construction, consulting

services, goods, non-consulting services.

The project uses a screening framework to propose a list of dams in order of investment

priority. The list of dams under this Component will be updated, reviewed and evaluated

annually.

MARD will select dams under the subproject priority investments according to the screening

framework applied to dams under the dam safety program. Dams will be prioritized for

investment selection based on both technical and economic criteria. Therefore, each sub-

project, in addition to assessing the risk criteria, needs to prepare carefully the economic

analysis when preparing the Feasibility Study Report.

2.3.2 Auxiliary items

Electricity and water for construction and daily life

Due to the nature of the project, the reservoir contains self-flowing water, so the demand is

negligible, mainly for lighting at night construction and iron-sheet formwork workshops. At

present, in the construction areas, there is a national power grid passing through, from the

national grid, according to the available 35KV line. In the construction site, 110KVA standby

generators are arranged in case of a power outage.

Use a pump to collect water from reservoir, contained in construction tanks at the construction

site. Depending on the quality of reservoir water, there are measures to treat by filtering tanks

to ensure water quality for domestic use and water for concrete construction.

Demand for workers' houses and construction camps

Demand for construction workers at peak time is about 960 people for 16 construction sites;

on average, each site has about 60 people; however, the number of workers at the construction

site is only about 15 people (about 25% of workers are from other places and 75% of workers

are hired labor in the locality) mainly technical and workers skilled, simple items hiring local

workers). Most of the project construction areas have quite favorable locations (the area of

downstream vacant land is wide and flat) to gather materials as well as workers' camps. The

material gathering yards are located near the housing area for convenient protection of

properties and temporary shelters for rain and sunshine. Toilets at the site are equipped to

meet the requirements of QCVN 01: 2011 / BYT on hygienic latrine standards; individual

activities and activities are carried out in the workers' housing area.

Landfills and soil borrow pits

Location of disposal sites at commune planning points, agreed by local authorities,

households, PPMUs and local authorities. Suitable location, convenient for transportation,

minimizing the impact on the environment and living of people.

The location of the land mines is surveyed and evaluated by the feasibility study consultant

(FS) and assesses the physical criteria in accordance with the earth embankment standards.

Materials of embankment soil in the construction items are exploited at the land mines

available under the planning of the province, meeting the conditions related to safety and

environmental protection.

2.5 Description of acitives implemented during the subproject

2.5.1. Pre-construction activities:

Before construction, activities include topographic survey, hydrology, meteorological

conditions, geological exploration drilling, reservoirs land acquisition, and mine clearance. In

the framework of the subproject there is no demolition work, however, vegetation clearing

activities are carried out by households affected by trees and crops. Waste from the

luminescent process will be collected and transported to the commune's disposal site by the

affected households.

The design of the subproject has considered the changes of climate factors in the subproject

area in recent times to serve as a basis for selecting the optimal design plan. The impact of

climate change in the past time has mainly been related to changes in rainfall causing floods,

landslides and droughts.

2.5.2. Plan for transportation of materials:

Construction materials will be gathered at the construction site before starting construction

45

about 1 week. Construction materials will be transported to the construction site at the time of

avoidance causing negative impacts on agricultural cultivation and activities of local people.

Workers, machines and expected volume of materials are presented in the sections above.

a. Timeline:

Construction time of a reservoir is expected to be 18 months

From November to February, construction of downstream, flooding, and overflowing roofs

are items not affected by irrigation water in Reservoir. At this time, water is taken through the

sewer as usual.

In the dry season, create a dike to construct the upstream roof. Continue executing and

completing items of downstream, flooding, and overflowing roofs. To ensure irrigation will

use pumps for irrigation. However, Reservoir Lang At must install additional water supply

pipes (about 80m HDPE D500 pipe) from the dyke to the water intake to ensure a stable

supply of water for all people in Yen The town and a part Lieu Do commune.

Construction of management road. The route is finally constructed to take advantage of the

dirt road to serve the construction and then proceed to upgrade hardening by concrete to

ensure durability for the road..

b. Construction of key works:

* Earth dam

Maintenance and upgrade:

- Excavating tarpaulin to repair downstream dam roof: Using bulldozer 110CV to bulldoze

dam dam. Because of the thickness of the unsheathed roof of the lower downstream, it is

impossible to use large equipment to construct because there is no ground to operate. So use

the main bulldozer to level and dig up the engine according to the design.

- Soil excavated upstream roofs are gathered in a concentrated pile to the left shoulder of the

dam, then use excavator 1.25m3 to stand on the road to pour into 7T cars to transport to

disposal sites

- Soil excavated downstream roof is ironed and leveled into the waste dump at the right foot

of the dam. After that, it will be transported by 7T car to transport waste to dumping ground.

Apply the structure of the dam roof:

- Due to the thickness of the cover to compensate small roofs, it is impossible to use large

equipment to construct because there is no ground to operate. So use the bulldozer to level up

and dress. The thickness of each layer of soil is to be compacted from 20 cm 30 cm, combined

with toads to dress manually at angled positions, sloping roof ...

- Reinforce the upstream roof with concrete slabs of M200 stone 1x2 with 12cm thickness

poured in place in reinforced concrete frame. Under the concrete layer is a 5 cm padding layer

to create a flat layer of 15cm thick macadam (using 1x2 stone). Under the lining layer is the

geotextile layer.

- Dimensions of cardboard slabs at blocks: 3.6x5 m (one small box)

- Concrete frame: Associated with reinforced concrete beams M200 stone 1x2 with type 1

(0.3x0,32cm), type 2 (0.2x0,32cm). For every 11.8m, make a big frame (1 unit), in which

divided into 6 small cells.

- The amount of concrete is low, small blocks should use a portable mixer of 500 liters to

mix mortar. Pour manually, use dress to dress concrete mortar.

46

Reinforcement of dam downstream:

- Downstream dam: To prevent roof erosion due to wind and rain, build cross-drainage

ditches on the dam roof. The grooves are made of concrete M200 stone 1x2 size 0.2x0.2 m

(roof groove), 0.3x0.3 m. Particularly, the foot groove to drain the dam body behind the rock

pile is made of stone plastered with the size of 0.4x0.4m. Alternating between cross-section

plots covering soil and growing grass.

The trenches are constructed on sloping roofs, the volume of concrete is low so use a 250 liter

mobile concrete mixing roof to mix mortar. Crafting using a dress to dress concrete mortar.

- The drainage foot of the dam body is built of stone with a thickness of 30 cm by hand.

- The foot of the downstream roof is constructed of prismatic stone with a manual

combination machine.

* Spillway and channel after overflow

The construction site is relatively convenient, the spillway is the traffic road, so the equipment

and facilities are easy to access.

Spill upgrade work:

- Foundation excavation spills an average depth of 1.3 m, average width of 7.5 m. The

method of using the digger 1.25 m3 combined with 7T cars to dig and transport to the waste

dump average 150 m.

- Overflowing: Use by hand and swamp dress.

- Overflowing concrete: The volume of concrete pouring is mainly concentrated in the

threshold and overflow slope. The bottom of the spill is 5.0 ÷ 10.0 m, concrete pouring is 30

to 40 cm thick. The wall overflowed from 1.6 to 6.0 m. Spill with a width of b> 5 m, the

motorbike equipment can move smoothly in the spillway to pour concrete. The direction of

pouring concrete from the upstream is receding to the downstream, using a damn dress to

compact concrete mortar.

* Road rescue combined with construction and operation management

Construction order: Construction starts from overflow line.

Task:

- Excavation and construction of the road base (20cm thick grading layer)

- The nylon layer is regenerated before pouring concrete to avoid dehydration for concrete

- Pouring the concrete surface layer BT M250 stone 1x2 20 cm thick, 3.5 m wide. At the

same time, construction of expansion joints and wheel guards.

- Finishing curbside, pouring concrete drainage ditches

- Plug the 10T load limit sign right at the beginning of the road.

Execution in the form of rolling, pouring concrete pouring road surface according to the

layout slot 6m a. Use a 500-liter mixer to mix concrete in place, dress with table dress and

punch dress..

c. Machinery:

- Soil excavation and transportation: Using the excavator set of 1.25m3, 7 ton automobile

transports to dumping ground at the prescribed location.

47

- Dam construction must comply with the regulations in TCVN 8297: 2009 "Irrigation

works - Earth dam - Technical requirements for construction by compaction method".

- Before and during the dam construction, it is necessary to conduct laboratory and field

tests as prescribed to determine appropriate embankment technology to ensure dam quality

according to design requirements.

- Concrete work: Concrete mixing with a 250-liter mixer, pour concrete by manual method.

Construction of concrete must comply with TCVN 4453-1995: Concrete and reinforced

concrete structure in accordance with TCVN 8218-2009 - Hydraulic concrete - Technical

requirements

- Working on upstream dam slope: using precast concrete panels using crane and installation

machines.

- The work of planting downstream grass: Roof protection grass is exploited in the

surrounding areas. It is necessary to plant grass to reinforce the roof right after finishing the

work, completing the project.

- Slab construction: Mainly using manual methods.

- Formwork work: Install formwork at handcrafted sections. Depending on the capacity of

the contractor, most steel formwork can be used for ease of installation and dismantling.

- Reinforcement work: Reinforcing steel is gathered and processed mainly in warehouse in

the premises and transported to the construction site. At the site, only small details are mainly

construction steel and auxiliary works.

- Other tasks: Mainly used manually

d. Transport organization in construction site:

Due to the small scale of the works, the upgraded Reservoir has been available in advance, so

it has access to the foot of the project.

For the dam site: Because Earth dam has a narrow ground, upgrading the dam only removes a

part of the land in the inclined roof and replaces it so it is impossible to arrange many vehicles

to walk on the tilted roof, affecting the security. Full construction and safety stability of the

dam. So transporting construction materials for dams is mainly used to transport from the top

of the dam up and down.

2.5.3. Operational and maintenance activities:

Periodic monitoring of dam safety: After damming and starting dam operation, the dam

management unit is responsible for dam safety monitoring, which is done by a qualified

independent expert. and who are not involved in the investigation, design, construction or

operation of the dam. After normal operation, dam tests are conducted regularly, including

safety checks before and after the annual flood season, in accordance with the Government's

Decree (No. 72/2007/ND-CP ) about Dam Safety Management.

After completion of the works, the operation of the dam will be the responsibility of the dam

management unit and then the responsibility of the PPMU will end.

Process of Reservoir, valve operation: The dam management unit must establish Reservoir

water regulation process, regulations on the storage and discharge of water in normal

conditions and in emergency situations, and submit to the management agency competent

state approves and organizes implementation. The dam management unit must formulate and

submit to competent authorities for promulgation or promulgate according to its authority

documents on operation and operation and operation procedures of each gate (hereinafter

48

referred to as operation). construction). Other issues need to be carried out according to the

Government's Decree No. 72/2007 / ND-CP on dam safety management.

2.6 Dam safety plan

A dam safety report (DSR) will be prepared for the subproject. The objective of the dam

safety report (DSR) is to present, analyze and make recommendations on: i) All conditions

that may affect the safety of dams and structures; ii) The impact of dams or sub-structures is

broken / uncontrollable due to harsh natural conditions, human errors or structural errors; and

iii) Institutional framework (at the present time) and in the future necessary to avoid or

minimize adverse conditions for dam safety.

After completing the review at the subproject screening stage, CPMU under MARD needs to

provide a DSR for each sub-project identified during the project implementation phase and

sent to PoE (consultant team). international dam safety) and the World Bank to consider. The

report must include findings and recommendations for any related safety issues, necessary

actions to be taken. Dam safety measures must be integrated into the design, construction and

operation of the Reservoir.

Review and analyze safety of dam structures: The review and evaluation of dams and related

structures will include, but are not limited to, the following:

- Review the survey materials on geological and material sources. Note the potential adverse

effects that may occur due to known geological characteristics. Evaluate unforeseen

conditions and remedial measures to align safety and operation issues of dams and related

facilities.

- Evaluate the suitability of dam type and spillway, the response of dam design, including the

proposed measures of foundation treatment, earthworks, load bearing parameters of selected,

permeable and Floating pressure control measures. Notice the safety perspective for any

unusual or missing aspects that occur and suggest measures to be taken.

- Evaluate stability, strength analysis and safety factors in normal, extraordinary and extreme

load conditions for Earth dams and concrete dams, spillway structures and water discharge

works, including the determination of geological impact criteria.

- Consider the stability factors of the Reservoir, formation of landslides, waves, and its effects

on dam stability;

- Consider the hydrological calculation method to determine the design flood of the project,

the Reservoir route and the size of the spillway. Review design of spillway works including

flow conditions, and energy dissipation works. Evaluate the discharge capacity of the spillway

in accordance with all design floods without damaging the dam.

- Consider the water intake and discharge works, including the hydraulic design, the

emergency reservoir discharge capacity, and the sedimentation process.

- Evaluate the design of spillways and door control devices, including the selection of the

number and type of main doors and valves, lifting equipment and other types of control

mechanisms. Special precautions should be taken for the standby system to operate spillways

with gates and flushing works when there are operational and electrical problems.

- Considering the designs of diversion works, construction progress, hydrology and risk

factors related to flow diversion during construction and filling of the flow at the start of

Reservoir storage phase.

- Considering the appropriateness of the measuring equipment, especially the markings or

tools, required in forecasting serious hazards or dam failure.

49

- Review the dam owner operation and maintenance process and emergency response plan,

including evaluation of subproject operational and maintenance factors related to dam safety

and capacity assessment operators to be able to perform maintenance and regular inspection

of the safety of the project.

Review and assessment of dam safety risks: In addition to ensuring dam structure safety, the

Project needs to assess the potential risks of dams for population and environment in the

downstream area of the dam, including including related works. Damage may not happen but

when it happens, it will cause serious damage. In this regard, during the preparation of the

project, as part of the DSR or the environmental and social management plan, the subproject

owner should make an assessment of the potential risk to the area. / downstream population.

For large and high-risk dams, data should be collected during the preparation process,

including topographic survey and land use downstream, to simulate a dam breach and flood.

Downstream flood dam according to different conditions / scenarios for the preparation of the

Emergency Response Plan. Data collection from upstream dams and / or watershed activities

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

for subprojects with pilot activities to promote active participation of local communities

should be considered. Residential communities around the dam area can participate in daily

surveillance, protect them from destructive activities of outside audiences, and participate in

simple maintenance tasks. A model with community involvement in dam safety activities

should also be considered. Sedimentation and pollution of upstream water sources can be a

serious problem for some river basins. The dam owner must commit to spending the budget

for proper operation and management of the dam, as well as periodical safety inspection.

province.

Compliance in implementing environmental and social impact assessments

The environmental and social impact assessment of the subproject will be implemented in

compliance with the environmental assessment procedures of the World Bank and the

Government of Vietnam. Specifically, the subproject environmental and social impact

assessment will have to comply with the project's Environmental and Social Management

framework, which has been reviewed and approved by the World Bank. Environmental and

social screening will be carried out for each sub-project to determine the appropriate size and

type of environmental assessment. On that basis, the TOR will be prepared for the assessment

of environmental and social impacts in accordance with the subproject scale and the potential

impacts predicted from the implementation of the subproject. Environmental and social

screening will be carried out by World Bank's safety policy experts. TORs for environmental

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

safeguard experts before conducting environmental and social impact assessments. During the

environmental and social impact assessment, consultations with affected people and local

NGOs need to be done. The report on environmental and social impact assessment will be

made public at the subproject implementation site in Vietnamese so that affected people and

local non-governmental organizations can easily access, and the local version He will be

publicized on the World Bank website before the subproject appraisal.

3.2 World Bank policies

The objective of these policies is to prevent and mitigate unnecessary harm to the people and

the natural environment during development. Safety policies provide the basis for stakeholder

engagement in project design, and act as an important tool to build ownership among local

people.

Effective impact and development of the Bank's support projects and programs have increased

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

available on its website at http://web.worldbank.org. The World Bank has listed social and

environmental protection policies.

3.2.1 Project level

The environmental and social screening of the Project is carried out in accordance with OP

4.01 and indicates 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),

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

International Waterways (OP / BP 7.50), Pest Management (OP 4.09) and Physical Cultural

Resources (OP / BP 4.11) will be applied to this Project. According to environmental

screening results, the project is classified as category A. In addition, the project also needs to

comply with World Bank requirements for community consultation and information

dissemination.

OP 4.09 Pest management

OP / BP 4.37 Safety of Dams

Social policies

OP / BP 4.10 Indigenous peoples

OP / BP 4.12 Involuntary resettlement

OP / BP 4.01 Environmental assessment

This policy is considered to be throughout the process of identifying, preventing and

minimizing potential negative environmental and social impacts related to the Bank's lending

activities. In the World Bank's operation, the purpose of environmental assessment is to

improve decision making, ensuring that project options are being considered and sustainable,

and the community is likely to be affected, must be consulted. The borrower is responsible for

conducting environmental assessments (EA) and the Bank advises borrowers upon request of

the Bank. The project is classified into one of four categories including A, B, C and FI,

depending on the location, sensitivity, scale of the project and the nature and magnitude of the

potential environmental impacts,

This subproject triggers OP 4.01 because it involves construction activities and operation of

reservoirs, and such activities will have negative environmental and social impacts. Based on

environmental screening results, the subproject is classified as Category B. In compliance

with OP 4.01 and the Government of Vietnam's Environmental Assessment, the subproject

has prepared an ESIA. After review and approval, the ESIA report of this sub-project will be

publicly disclosed at subproject sites accesible to locally-affected people and local NGOs, and

on on the World Bank external website.

OP 4.09 Pest management

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

risks associated with pesticide use, promote and support safe, effective and friendly pest

management. with the environment. Procurement of pesticides in a Bank-financed project

must be assessed for the nature and extent of the risk involved, taking into account the

proposed and intended use. In order to manage pests that affect either the agricultural or

public health sectors, the Bank supports a strategy to promote the use of biological control

methods and reduce dependence on pesticides. chemistry. In World Bank loan projects,

borrowers address pest management issues in accordance with the environmental assessment

context of the project. In assessing a project related to pest management, the Bank will assess

the borrower's legal, institutional and legal capacity to promote and support a safe pest

management program. , efficient and environmentally friendly. This subproject triggers this

policy because of an increase of 109 ha of winter-spring paddy area (increasing from 660 ha

to 769 ha) and 120 ha of summer-autumn rice (increasing from 612 ha to 732 ha) after the

dam will be rehabilitated.

OP / BP 4.37 Safety of Dams

This policy is triggered for the whole project because of the safety activities of the dams

related to environmental and socio-economic development. When borrowing from the World

Bank to build new dams, the proposed Dam Safety Policy is based on the opinions of

experienced experts and is responsible for the design and supervision of construction, the

56

borrower passes Dam safety measures and implemente throughout a project cycle. This policy

also applies to the recovery of Reservoiri and the safety of existing dams, which affect the

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

additional dam safety measures should be proposed. The OP 4.37 policy recommends, in

appropriate conditions, that Bank staff will discuss with borrowers the necessary measures to

strengthen the institutional, legal and regulatory framework for dam safety programs.

OP / BP 4.12 Involuntary resettlement

Non-Voluntary Resettlement Policy to address long-term difficulties, poverty and

environmental impacts on affected people during resettlement process. The OP 4.12 policy

applies whether or not the affected person must be relocated. The bank describes all the

processes of "involuntary resettlement", or merely resettlement, even when the affected

people are not required to relocate. Resettlement is not voluntary when the government has

the right to requisition land or other assets, and when the affected people have no other option

to maintain their livelihood.

This policy is applied because this subproject causes impacts on Reservoirs land collection of

38 households; in which, (i) 1 household is affected on agricultural production land (land for

annual crops), no household is severely affected by losing 20% or more of agricultural land;

(ii) 32 households are affected by forest land and (iii) 9 households have crops affected on the

land managed by the Commune People's Committee; In addition, there is damage to trees and

crops on reservoirland to build the subproject.

OP / BP 4.10 Indigenous peoples

The policy definiensethnic minorityby geographical areas, especially by the presence of

different levels of the following characteristics:

- Self-sticking as members of different ethnic groups and recognized for this characteristic by

others

- Living closely in a geographically distinct environment or ancestral territory left in the

project area and close to nature in that habitat and territory

- Customary cultural, economic, social or political institutions that are different from those of

the majority of culture and society

- Language of ethnic minorities is often different from the official language of the region or

country.

Mandatory conditions for approving investment projects, OP 4.10 requires borrowers to

consult and disclose information to vulnerable ethnic minorities and establish a broad

community support model. for the subprojects and its objectives. The Bank-financed project

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

communities; or (b) when evading is not feasible, methods must be proposed to minimize,

minimize, or compensate for impacts.

This policy is applied because there are 14 households in the area (36.8%) of Tay, Muong and

Cao Lan ethnic groups. benefit from the subproject in 15 communes, especially Muong Lai

and Minh Xuan communes, Luc Yen district; Tich Coc commune, Yen Binh district, Yen Phu

commune, Van Yen district are communes where people in the commune are mainly ethnic.

WBG EHS guidelines

The WB and IFC’s guidelines on EHS was launched in 2008, which is an important guideline

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

This guide sets out the goals that need to be achieved and which measures need to be used to

57

bring the best performance at a reasonable cost. This guide can be accessed at

http://www.ifc.org.

The World Bank policy on Access to information

In addition to environmental safeguard policies, to promote transparency and accountability,

the Bank also provides access to information related to proposed safety measures. The bank

proposes this policy to support borrower and Bank decision making by allowing borrowers to

access information about the environmental and social aspects of the project at the website

with native language that is easy to understand and intuitive. The Bank ensures that

environmental and social protection documents related to the project, as well as preparation

procedures related to the subprojects, are introduced in a timely manner prior to appraisal.

Information access policy requires information disclosure in both English and native

languages (Vietnamese) and meets World Bank standards.

4.1.2. Conditions on terrain

Yen Bai is a transition area from the northwest high mountains belonging to Hoang Lien -

Pung Luong mountain range and Con Voi mountain range down the midland hills of Phu Tho.

Yen Bai is also the contiguous area between the northwestern mountains and the northeastern

mountains, the mountain ranges run in the northwest - southeast direction. The average height

of the province is 600 m, the lowest place in Minh Quan commune has a height of 20 m, the

highest is Pung Luong peak with elevation of 2,986 m. Because of its mountainous terrain, the

land of Yen Bai province has a very complex terrain, strongly divided by high mountains,

streams and narrow valleys. Specifically, in the subproject areas as follows:

Yen Binh district: there is a transition topography from midland to mountainous area,

gradually rising terrain from Southeast - Northwest is created by 2 mountain ranges: Cao Bien

mountain range lies on the left bank of Chay river (Thac Ba lake) including hills and

mountains with a height of 300-600m running in the direction of Northwest - Southeast; The

Con Voi Mountain Range is an ancient mountain system located on the right bank of Chay

River, including low mountains, comfortable slopes, below the ground covered with

crystalline schist shale, an altitude of 400 - 700m running along the Northwest - East South

and water surface area of Thac Ba lake is 15,900 ha (part of the territory of Yen Binh district)

with more than 1,300 islands.

Specifically, the basin's topography is located in Yen Binh district, Yen Bai province, on the

left bank of the River Chay in the northeastern area of Thac Ba Lake with medium and

mountainous terrain, the average height is from 50 to 200m. Small rivers and streams and

slopes and basins are often small, so the water supply sources for lakes are often limited in the

dry season. The lake is built with 1 earthen dam> 20 m high. Surrounding the lake are

continuous high mountains with a height of <200m.

Van Yen district: The topography of the district is relatively complicated, with continuous

hills and mountains and gradually rising from the southeast to northwest in the Red River

valley between the high mountains Con Voi and Pung Luong; The river system is dense with

different types of terrain: rugged high mountains, wavy and undulating hilly areas

interspersed with valleys and narrow alluvial fields along the river. The mountainous area is

65

concentrated mainly in the northwest communes of the district, is a series of mountains and

hills that are strongly divided, high slopes, making it difficult to travel and economic

exchanges, yet favorable for development. forestry and growing high value perennial crops

such as cinnamon and other forest trees. High hills and low mountains belong to the western

communes of the district, this area is sharp peaks, steep slopes, deep and narrow waterfalls,

suitable for industrial crops, fruit trees and cattle breeding. The rest of the lowland communes

of the district have topography with round bowl shape, round peak, comfortable slopes are

very convenient for growing long-term industrial crops, fruit trees, livestock and poultry and

food crops. Specifically:

- Ho Khe Vai, Xuan Ai commune, the lake has a palm shape. The bottom elevation of the

reservoir bed is the lowest + 62m, the elevation of the present earth dam crest + 77.6m, the

elevation of NWL (coinciding with the free spill threshold) + 76.2 m. Average elevation of

irrigation area + 49 ÷ 53m. Thus, the altitude of self-control irrigation is fully met.

- Reservoirs Khe Dua is located in Yen Phu commune, Van Yen district, Yên Bái province,

the lake runs along the stream bed with a length of 2.1 km, an average width of 140m. The

bottom elevation of the reservoir bed is the lowest + 40m, the elevation of the earth dam crest

is currently + 57.6m, elevation of NWL (coinciding with the free spill threshold) + 56m. The

average elevation of irrigation area +40 ÷ 42m. Thus, the altitude of self-control irrigation is

fully met.

- Ho Khe Chinh is located in An Thinh commune, Van Yen district, Yen Bai province, on the

right bank of the Red River in the low mountains with an average height of 20 to 200m. Small

rivers and streams and slopes and basins are often small, so the water supply sources for lakes

are often limited in the dry season.

- Ho Khe Ngang and Khe Hop are located in Yen Hop commune, Van Yen district, Yen Bai

province, on the right bank of the Red River in low mountainous areas with an average height

of 20 to 200m. The lake is located between two mountain ranges running parallel to the

Northeast - Southwest with the height <200m.

Luc Yen district: The terrain is divided by two main mountain ranges running along the

Northwest-Southeast direction, creating flat valleys and basins where the population is

concentrated and living for a long time.

On the right bank of Chay river is the Con Voi mountain range running along the Northwest-

Southeast direction, with an average altitude of 300-400m, the highest peak of 1,148m,

around the peak, a sloping slope and an average slope of 400. The terrain is divided into small

valleys and streams. The whole area is ancient rock and soil, which weathered the natural

forest with 50% of its area, capable of developing forestry, industrial and agricultural trees.

On the left bank of Chay river is a large rocky mountain range running along the Northwest-

Southeast direction with an average height of 935 m, the highest peak of 1,035 m, with a steep

slope, sharp peaks, cut mountain slopes, a slope 700 or more, most of the rocky mountains

have natural forests, the current forest coverage is 42.6%. This is a series of Limestone

Mountains with precious and rare mineral resources, which are gradually invested in research,

exploration, and exploitation.

The flat lowlands are interspersed between the two mountains and the river. Flowing fertile

land is the concentration of population living and producing agriculture and forestry.

Thac Ba lake area was formed in 1970 after the construction of a hydropower plant, with a

total water surface area of 11 communes in Luc Yen District Lake is 4,560.5 ha.

The topography of the lake basin of Luc Yen district, Yen Bai province is located on the left

66

bank of the River Chay in the northern upstream area of Thac Ba Lake with medium and

mountainous terrain, the average height is from 50 to 200m. Small rivers and streams and

slopes and basins are often small, so the water supply sources for lakes are often limited in the

dry season. Surrounding the lake are continuous high mountains with a height of <200m.

Tran Yen district: Tran Yen has a transition terrain from Midland to the mountainous area,

constructed by Pu Luong mountain range at Huu Ngan and Con Voi mountain range on the

left bank of Red River, running in the direction of Northwest - Southeast The average height

is 100 - 200m above sea level. The lowest place is Minh Quan commune with a height of

20m. In general, the terrain gradually increases from the Southeast to the Northwest. The

southern communes have the topography, which is a bowl-shaped hill, the top of the slope is

convenient for growing food crops and industrial trees. The communes located at the foot of

the Con Voi mountain range and Pu Luong mountain range have complex topography,

separation, hills and mountains, and deep and steep valleys, making it difficult to travel and

economic exchanges. However, it is also a favorable condition for the development of forestry

and animal husbandry. Specifically at the following works:

- Ho Tu Do is located in Y Can commune, Tran Yen district, Yen Bai province, on the right

bank of the Red River in low mountainous areas with an average height of 20 to 200m. Small

rivers and streams and slopes and basins are often small, so the water supply sources for lakes

are often limited in the dry season. The lake is constructed of 5 small dams connected

between the top of the hill. The mountains and hills around the lake have low elevations

<200m.

- Ho Chi Minh Lake Although located in Cuong Thinh commune, Tran Yen district, Yen Bai

province, on the left bank of the Red River lies the mountain foot belt of the elephant with

medium and mountainous terrain, the average height is from 50 to 200m. Small rivers and

streams and slopes and basins are often small, so the water supply sources for lakes are often

limited in the dry season. Surrounding the lake are consecutive hill ranges with a height of

<200m.

Van Chan district: Van Chan is located on the northeast side of Hoang Lien Son range. The

terrain is complex, there are many forests, mountains, caves, intertwined stream streams, flat

valleys. The average height is 400m above sea level. Although the terrain is quite

complicated, but divided into 3 economic sub-regions: The inner region (Muong Lo field)

consists of 12 communes, which are relatively flat, with Muong Lo fields of over 2,400

hectares, ranking second in four wings. Northwestern copper. Outside: including 9 communes

and towns, has advantages in developing hill gardens, forest gardens and growing wet rice.

Upland district: including 10 communes, with an average altitude of 600 m or more, potential

in land, forest products, minerals, cattle breeding.

Hydrogeology: In the area of Yen Bai province, it mainly distributes fissure water types, and

water distribution holes are very limited. Water holes are mainly distributed along the Red

River. In the upper part, the composition is fine grain, the level of water is poor, the coarse

part of the grain consists of gravel, pebbles of large size (over 10cm). According to actual

observations and surveys on the face, the wells in this area are quite rich in water. Clear

water, light and can be used as a source.

Fissure water occupies most of the province's area. The rock containing water is quite ancient,

mainly Paletozoic metamorphic sediments to Proterozoic and magma rocks. Young Mezozoi

younger formations are less common. In general, the water level of cracked rock in Yen Bai is

poor. According to the survey results, in Yen Bai, there is little water flow with large flow.

Most circuits have Q <0.5l / s, crack water has a small total mineralization (m <0.5 g / l),

water of Bicarbonat-Sodium type, neutral reaction (PH ~ 6.5 - 7.5). Good water quality, can

be used to store for people, economy.

4.1.4. Climate and weather conditions

Climate characteristics: Yen Bai is located in the tropical monsoon climate zone, forming 2

distinct seasons every year:

- Rainy season: From April to October, the average temperature is 250C, the hottest month is

July, there are days when the temperature reaches 370C - 380C. The average rainfall this

season accounts for 80-85% of the annual rainfall, there are a lot of rainy days, a great

intensity, especially in June, July and August, there is often heavy rain accompanied by

tornadoes, hail, causing floods sweeping, flooding in rivers and streams, damaging irrigation

works, can cause damage to production and life.

- Dry season: From November to March of the following year, the average temperature:

180C, the coldest month is January, the lowest temperature is 10C, the rainfall of this season

is too little to supply water for production and life, and thus drought should happen. Besides,

hoarfrost, fog, and low sunlight also affect agricultural production, especially in 2 upland

districts: Tram Tau and Mu Cang Chai.

Climate sub-regions: Yen Bai can be divided into 5 sub-regions as follows:

- Mu Cang Chai high mountain area: At an altitude of 800 - 1,200 m, the average temperature

is from 18 - 200C, there are many hoarfrost, frost, summer with windy winds, average rainfall

is 1,900 mm. Suitable for developing temperate plants and animals.

- High hills and low mountains in the valley of Thao river and Chay river: At an altitude of

300-800 m, the average temperature is from 210C - 230C, the lowest is 200C, the average

rainfall is 1,600 - 1,800 mm. Suitable for developing forest tree groups such as Cinnamon,

wood material, big wood.

- Southern Tran Yen area, Yen Bai city: The average height is from 100-300 m, the average

temperature is between 230C - 240C, the lowest is 30C, the average rainfall is 1,800 - 2000

mm, and the average humidity is 87%. Winter is heavily influenced by the northeast

monsoon, the region with the most drizzle in the province. The climate of this region is

suitable for growing food crops, fruit trees, industrial and forestry trees.

- Upper and upper regions of Van Chan district: At an altitude of 200-400 m, the average

temperature is from 220C - 230C, the lowest is 10C with rainfall from 1,400 - 1,600 mm. The

climate of this region is suitable for food crops, fruit trees, tea trees and forest trees.

69

- The highland area of southwest Van Chan: At an altitude of 800 - 1,000 m, the average

temperature is 180C, the Northern rainfall is 1,800 - 2,000 mm and the south is 1,400 mm.

- The area of Luc Yen - Yen Binh: At an altitude of 100 - 300 m, the average temperature is

200C - 230C, the average rainfall is 1,800 - 2,000 mm, the average humidity is 87%. Winter

climate is less cold, cool in summer due to much influence of Thac Ba lake, suitable for

agricultural and forestry crops, exploitation and aquaculture, especially tourism potential.

Rain characteristics: In general, the rainfall in Yen Bai is relatively large, the average annual

rainfall is 1,500 mm - 2,200 mm, depending on different regions. Rainy season usually lasts

from May to October, rainfall in the rainy season accounts for 80-85% of the annual rainfall.

Especially 3 months with high intensity of rain is June, July and August, accounting for 45 -

55% of the annual rainfall. The dry season from November to April next year, rainfall

accounts for only 15-20% of the annual rainfall. December, January and February are the

driest months, crops often lack water during this time.

Moisture, evaporation:

Humidity: Yen Bai is located in the tropical monsoon climate, so the average humidity in the

province is relatively high, due to complicated terrain conditions, the climate characteristics

are divided into different regions so the humidity is different between regions. Through actual

data measured in some stations, the highest humidity is 94% and March in Yen Bai, the

smallest humidity is 79% in July in Thac Ba area, the average humidity of the province is 86 -

88%. With this humidity, it is very suitable to develop agro-forestry crops

Evaporation: Yen Bai has a relatively high moisture content, so the annual evaporation is

relatively small, ranging from 600 to 700 mm. Particularly in the western area of Hoang Lien

Son range due to the influence of hot and dry southwest wind (Laos wind) blowing from the

mainland to the sea, the large evaporation, this area has an average annual evaporation of up

to 1,000 mm.

Wind and storm regime: The geographical position and terrain structure of the province have

a great influence on the wind regime. In winter, the Northeast monsoon blows in the East-

North direction to the South-West. In the summer, the hot and humid southeast wind blows in

the southeast - northwest direction along the valleys of Thao and Chay rivers to the north of

the province, facing high mountains, causing heavy rain in the mountains. For the western

region of Hoang Lien Son range, there is southwest wind (Lao wind), hot dry blowing to

make the climate different from the East. The swirling valleys are often Van Chan and Luc

Yen.

4.1.5. River network

Rivers and streams: Yen Bai province has a complex and strongly divided terrain, relatively

large rainfall in Yen Bai province is quite dense, distributed throughout the territory, very

convenient for construction of irrigation works. and supply daily-life water for agricultural

and forestry production and daily life; contribute to regulating climate, creating a network of

transporting goods, developing husbandry and aquaculture; The rivers and streams have a

steep slope, which has the potential to develop hydropower especially in remote and highland

communes. But in addition to the positive aspects, floods often occur in the flood season,

inundation of riparian areas and large tributaries causing significant damage to agricultural

production, people's properties and damaging public works irrigation process. In dry season,

low water level must use pumps to exploit water sources for production and life. On average,

Yen Bai receives about 13 billion cubic meters of rain from the peaks to small, concentrated

streams, forming 296 streams of 4 river systems:

70

- Red River originates from Yunnan province - China, flows in the Northwest - Southeast

direction, runs through Yen Bai province with a length of 120.5 km with a basin area of 2,700

km2, with 155 nibs and other tributaries, of which there are four major tributaries: Thia nibs,

Hop nibs, Ngoi Lau and Lao fuses.

- Chay river originates from Tay Con Linh mountain flowing along the Northwest - Southeast

direction, flowing through Yen Bai territory with 48.3 km long, the basin area is 2,200 km2,

meandering, deep and narrow riverbed , squeezing. The river basin has 97 streams, the

downstream area is Thac Ba hydropower reservoir.

- 42 streams of Da river system, flowing through Mu Cang Chai district, the largest tributary

is Nam Kim stream.

- 2 streams (Co and Nuoc Co streams) belonging to Lo river system flowing in Khanh Thien

commune, Luc Yen district.

Ponds, lakes and lagoons: Yen Bai has about 23,000 ha of ponds and reservoirs, including

Thac Ba lake with a total area of 19,050 ha, in addition to the main effect of the reservoir of

Thac Ba hydropower project and the remaining lake has the effect of supplying water for

daily life, regulating climate and environment in the region and having great advantages for

aquaculture and tourism development.

Quality of rivers and streams, ponds and lakes of Yen Bai is generally relatively good, less

polluted, meeting the requirements for production and living.

Yen Bai has a significant source of groundwater, but is unevenly distributed, the water table

changes, some places are only a few meters, but there are some tens of meters where there is

water. It is possible to exploit groundwater to supply daily-life water through wells and

drilling wells living through wells and drilling wells.

4.1.6. Biodiversity

Yen Bai is a mountainous province in the Northwest region, forestry area accounts for 68.9%

of the total natural area; agricultural land accounts for 15.5% of the natural area and the

system of ponds and lakes is quite abundant with tropical monsoon climate conditions

creating a diversity of ecosystems in the province. The abundance of animals, plants and

genetic resources has contributed greatly to the province's economic development. According

to the report on environmental status of Yen Bai province in 2014; Biological resources in the

area with many kinds of flora and fauna in natural ecosystem conservation areas such as Mu

Cang Chai Species and Habitat Conservation Area, Na Hau Nature Reserve, nature

conservation area Tan Phuong commune, Luc Yen district, Thuong Bang La district, Van

Chan district, Viet Hong forest in Tran Yen district, ... However, the sub-project

implementation area is far from the nature conservation area.

Flora

The vegetation around the lake area is mainly hill gardens, including long-term industrial

trees, timber trees, fruit trees and broad-leaved trees, grown at an altitude of 200-600 m. The

area is covered with a quite large area in the districts of Van Yen, Luc Yen and Van Chan. In

areas of valleys and rivers (Yen Binh and Tran Yen districts), food crops and vegetables are

also grown. In addition, the area also has secondary shrubs and grasslands after exploitation.

The construction area of the subproject items is mainly production forest vegetation, perennial

industrial trees, timber trees, vegetables and regenerated shrubs such as Cinnamon, Tea,

Eucalyptus, bamboo and Glue, ... and fruit trees such as oranges, grapefruit, longan, litchi,

lemon, jackfruit, ...

of the subproject as well as ecological sensitive objects and specific mitigation measures will

be required for these ecosystems.

4.2 Impact of climate change on Yen Bai province

4.2.1. Prolonged heat on high heat background

One of the effects of climate change is most pronounced in any changeusually of the weather,

prolonged heat waves on high temperature have affected. Not small to the health of the

people. Typical extreme weather phenomenonprolonged heat and drought occurred from 25/5

- 4/6/2015, the highest temperature was 38.1 - 40.0oC (Nghia Lo town, the highest

temperature is 40oC) hot weather during this time was recorded received the hottest heat wave

in 15 years, other times the highest temperature was 35.3 - 39.3oC. The prolonged heat waves

are the causes that affect human health, causing drought to affect agricultural production and

fisheries and increase the level of forest fire.

4.2.2. Increased cold period

In addition to the prolonged heatwaves, climate change also causes problems long-lasting,

cold cold objects seriously affect people and pets. In the period of 2011 - 2016, the annual

average temperature in the regions in the province tends to increase; weather changes are

unusual; Extreme heat-related events such as cold, cold, cold air occur earlier than the average

for many years.

These climate changes have directly impacted on people's life and activities, adversely

affected agricultural and forestry production, increased flash floods and natural disasters;

increasing social costs as well as costs for natural disasters, creating a heavy burden for a

mountainous province like Yen Bai.

In 2017 alone, from August to October, in the province, there were continuous floods and

flash floods in districts: Tram Tau, Mu Cang Chai, Nghia Lo and Van Chan, causing hundreds

of losses hectares of crops, completely collapsing hundreds of houses, destroying many roads,

irrigation works, schools; swept away, killed and disappeared many people. Estimates of

damage caused by flooding with the above-mentioned districts amounted to trillions of dong,

accompanied by tremendous pain for families whose relatives were killed by floods.

4.2.3. Increased storms and tropical depressions and unpredictable developments

The effects of climate change on Yen Bai are most evident in the characteristics of the

number and frequency of storms and tropical depressions hitting the province. According to

statistics of the Steering Committee for Natural Disaster Prevention and Rescue Search,

Department of Agriculture and Rural Development and Hydrometeorology Station of Yen Bai

province showed that in 2015, there were 23 storms and tropical depressions. In the province,

causing serious damage to people and property. The storms and tropical depressions in the

period from 2008 up to now have an unusually large number of frequencies, predictive

characteristics and influences and do not follow the rules, thus causing many difficulties for

prevention and response to incidents.

4.2.4. Forest fires, floods and dam failure incidents

The situation of forest fires in Yen Bai province, especially in the western region of the

province is happening very complicated. Fires occurred continuously, in many different areas,

73

making rescue work difficult. In 2016 alone, Yen Bai province has 21 forest fires with a total

area of 18.5 ha. Most recently, according to the report of the agriculture sector from 02-04 /

3/2018, there were 2 forest fires in the province that initially identified the damage of about

07 ha of planted forest (1 case in Lang Nhi commune, Tram Tau district causes damage: 2 ha,

1 case in Phuc Son commune, Van Chan district with 5 ha damage. Estimated loss in 2016 is

about VND 15 billion.

Floods and storms and tropical depressions are natural disasters that cause environmental

incidents. In 2016 alone, in Yen Bai province, there were 14 natural disasters (02 cold and

cold spells; 06 whirlwinds; 03 storms and 3 heavy rains with thunderstorms and lightning)

causing damage harm to people and houses of people. Incident of the dike was collapsed and

damaged, including 02 dikes in Tran Yen district: De Cau Dat town of Co Phuc town was

broken with vanes at the culvert under the foot of the dike, leaking the dike body of the

village 2 to village 4, threatening the dyke break when the river is high; Phu Tho dyke in Viet

Thanh commune has a sinking hole and a slippery position of the upstream dyke is in danger

of breaking the dyke, causing unsafety.

In the reservoirs of the subproject, storms and tropical depressions have caused the

phenomenon of slipping, sliding dams and dam surface erosion, causing the risk of unsafe for

downstream areas. The history of storm records shows that in 2003, floods and storms broke

the dam near the spillway of Nghia Lo Farm reservoir, completely damaging houses of 29

households and losing about 5ha of area of planting crops of Nam Han 2 and Nam Han 3

villages of Phu Nham. Estimated losses amounted to VND 30 billion. In 2005, also at Nghia

Lo Agricultural Lake due to the impact of the storm No. 5, it broke the dam, the incident was

discovered by the management unit promptly so it did not cause significant damage.

4.3 Status of physical environment components

The background environment status is shown through the parameters of soil, water and air

quality, measured in the field, analyzed in the laboratory. The environmental status of the

project area is evaluated by two main methods as follows:

- Rapid method of measuring environment with the most advanced equipment today.

- Laboratory analysis method according to Villas standards (ISO 17025: 2005)

The equipment used for rapid assessment of the environment includes:

4.1.6.1. Air environment and noise

The indicators for monitoring include: temperature, humidity, wind direction, wind speed,

74

suspended dust, and concentration of air pollutants NO2, SO2, CO.

Measuring noise and vibration levels: Because the communes in the subproject area are

mostly located in the valley, surrounded by hills and mountains and away from residential

areas. Location of monitoring samples: Conducting measurements at the locations on the

headworks of the lakes are sensitive and typical positions that describe the characteristics of

the subproject area air (Geographic coordinates of Sample location and sample analysis

results are in Appendix 2).

- Sampling time: From November 13, 2017 to November 29, 2017

Review and evaluation:

Monitoring results show that the air environment quality in the subproject implementation

area is ensured compared to the standard, the area of 16 lakes is located in the valley,

surrounded by hills and forests, away from the residential area, cool climatic conditions,

production forest vegetation, well developed shrub, monitoring parameters are within the

limits of QCVN 05: 2013/BTNMT on ambient air quality (dust, NO2, SO2, CO).

4.1.6.2. Water Environment

a. Surface water

- Analytical indicators: pH, TSS, DO, COD, BOD5, NH4 +, NO2-, NO3-, PO43- Pb, Zn, Fe,

Cr, Hg, As, Coliform.

- Methods of monitoring and analysis: Rapid measurement method in the field and taking

samples to the laboratory to analyze and comply with the regulations of the Ministry of

Natural Resources and Environment

- Sample preservation method: Samples are taken in accordance with the current regulations

and regulations of the Ministry of Natural Resources and Environment, samples are kept

tightly closed and kept cold during transportation from the sampling area to the laboratory.

- Location of surface water sampling points: locations for monitoring and collecting samples

for surface water quality analysis (Geographic coordinates of sampling locations and sample

analysis results are in Appendix 2).

- Sampling time: From November 13, 2017 to November 29, 2017

Review and evaluation

Comparing the results of surface water quality analysis at the monitoring sites with QCVN

08-MT: 2015 / BTNMT column B1 shows that: At the time of sampling, most of the

environmental parameters are smaller than the standard respectively. So, in general, surface

water quality here has not shown signs of being contaminated by activities of people.

b. Groundwater

- Analysis indicators: pH, CaCO3, SS, DO, NH4 +, NO2-, NO3-, Cl-, Pb, Zn, Fe, Cu, Cd, Cr,

Hg, As, Coliform.

- Methods of monitoring and analysis: Rapid measurement method in the field and taking

samples to the laboratory to analyze and comply with the regulations of the Ministry of

Natural Resources and Environment

- Sample preservation method: Samples are taken in accordance with the current regulations

and regulations of the Ministry of Natural Resources and Environment, samples are kept

tightly closed and kept cold during transportation from the sampling area to the laboratory.

75

- Sample monitoring locations: Carry out sampling of groundwater in the subproject area and

the nearest residential area (Geographic coordinates of sampling locations and sample

analysis results see Annex 2).

- Sampling time: From November 13, 2017 to November 29, 2017.


Through the analysis results, most of the parameters of groundwater quality analysis in the

subproject area are under QCVN 09-MT: 2015 / BTNMT. However, the density of Coliforms

in some locations exceeds the standard as follows:

- The position of NN18 is approximately 3.7 times higher.


- NN28 position exceeds 5 times.


- The NN34 position is approximately 1.3 times higher

4.1.6.3. Earth environment

- Analysis criteria: Zn, Pb, As, Cd, Cu.

- Sample monitoring locations: Conduct soil sampling at the foot of the dam and downstream

residential area (Geographic coordinates of sampling locations and sample analysis results see

Annex 2).

- Sampling time: From November 13, 2017 to November 29, 2017.


From the analysis results compared with QCVN 03: 2015 / BTNMT, the soil samples

collected in the subproject area show signs of pollution of As content. The analytical

parameters are under the permitted standards, however, As content in some locations exceeds

the permitted standards, the highest concentration is in the area of Phu Nham lake with the

content of As in excess 4.16 times compared with agricultural land standards and 3.12 times

higher than the forestry land standards.

4.4 Socio-economic conditions of the sub-project area

Yen Bai is the gateway to the Northwest, located on the midpoint of one of the main

economic corridors of Kunming - Lao Cai - Hanoi - Hai Phong, with a relatively diverse

transport system; The passing of Hanoi - Lao Cai expressway has created favorable conditions

and opportunities for Yen Bai to enhance its integration and economic and trade exchange and

socio-cultural development not only with the provinces in the region but major economic

centers throughout the country but also in international economic exchanges, especially with

the southwestern provinces of China and ASEAN countries.

In recent years, the economic structure of Yen Bai is shifting towards reducing the rate of

agriculture, forestry and fishery, maintaining the rate in the construction industry, increasing

the proportion of service value; forming strategic goods products on a large scale and

gradually reaching a stable level.

The infrastructure system in Yen Bai, especially in rural areas, has improved markedly in

recent years, the basic transport system is favorable to villages and many rural roads have

been hardening. Many irrigation works have been upgraded and basically renewed the

irrigation response. The rate of rural households using electricity for daily life has been

improved. However, Yen Bai infrastructure still does not meet the demand of social

76

development. It is necessary to mobilize a lot of investment capital for the development of the

infrastructure system, first of all: transportation, electricity, irrigation ...

In recent years, the socio-economic situation of 5 districts in general and 14 communes in

particular in the subproject area has made positive changes: stable economy and continued

growth and social culture. There are new developments, security and order situation in 14

communes is well maintained, 14/14 communes meet the criteria of security and order in the

criteria of new rural construction, ensuring safety social. However, the main source of income

of the people is from agriculture, the main agricultural production activities are the cultivation

of rice, corn and growing crops divided into 2 main seasons of the year. From February to

June, the season is from August to December. In addition, some communes have a very large

area of production forest land, planting long-term industrial crops with different kinds of trees

with high economic value such as Tea, Cinnamon, Fruit also provides a stable income for

farmers.

a) Infrastructure

i. Transportation

Transportation infrastructure in Yen Bai province currently has 4 types of transportation:

roads, railways, waterways and airways. In which, road traffic plays a key role. By the end of

2016, the road traffic network in the province has 01 highway with a length of 80.5Km; 4

national highways (QL70, QL32, QL32C and QL37) with a total length of 374Km; 14

provincial roads with a total length of 491Km; 244.5Km of urban roads; 62Km of dedicated

road; 1,361 km of district roads; 3.131Km of the commune and 2,148Km of the village.

In the province, there is Hanoi - Lao Cai railway line located on the economic corridor of

Kunming - Lao Cai - Hanoi - Hai Phong - Quang Ninh. This railway plays an important role

in transporting goods and passengers between Yunnan Province, China and Vietnam. The

entire route has a length of 296Km, of which the section passing Yen Bai province has a

length of 88.2Km, including 10 stations (01 grade 2 and 09 grade 4 stations). This is a single

meter railway, built in the late 19th century and put into operation in the early 20th century.

The waterway in Yen Bai province is formed on two main areas: the waterway of the Red

River and the waterway of Thac Ba Lake.

- The Red River route running through the territory of Yen Bai province has the

characteristics of a mountainous and river river in a natural state with a length of 90km

managed by the Northern Inland Waterway Administration and the Region II Waterway Port

Authority. Currently, only 10km downstream from Van Phu bridge to Yen Bai city of grade

IV river is circulated all year round; The section from Yen Bai City - Lao Cai is 80km long

without technical decentralization, there are many rapids, shallow beaches, dry season and dry

season, fast flooding season is only suitable for small vehicles.

- Inland waterway of Thac Ba Lake holds an important position in inland waterway transport,

affecting the climate and environment of 2 districts of Yen Binh and Luc Yen and ensuring

the transport of materials for the southern industrial park of the province. Currently

management agencies are the Department of Inland Waterway Management in the North and

the Waterway Port of Region II has installed a waterway signaling system on some main

routes, convenient transportation and transportation facilities around year.

Yen Bai has an airport located close to the city, this is a level II military airport qualified for

medium and light aircraft to go up and down like A320 and AL26. The runway system is 02

km long and the parking space is suitable for medium-class military aircraft. The system of

flight control radio control stations is managed by the Ministry of Defense. At present, Yen

Bai airport has favorable conditions, can be upgraded to become a mixed airport of military

77

and civil aviation station serving the provinces in the Northwest region such as Yen Bai, Lao

Cai, Tuyen Quang , Ha Giang.

ii. Irrigation infrastructure

In addition to solidifying the main canals, the in-field canal system in the subproject

communes has also been completed, step by step concretized, convenient for active irrigation.

Besides, Yen Bai province has instructed localities to continue upgrading in-field irrigation

systems to effectively use irrigation water.

iii. Water supply

Households in the subproject area mainly use drilled / dug wells for eating / drinking / bathing

/ washing, or generally for domestic use, the response rate is 92.78% used for eating /

drinking as well as bathing and having 5.6% using water from ponds, lakes and rivers for

drinking and 5.74% for bathing and washing. Area of communes in the subproject No

commune has a clean water plant yet, a small number of households have access to clean

80

water for drinking and bathing due to the use of clean water pipes from other commune clean

water plants .

Water used for production comes mainly from irrigation systems (86.58%), and natural river /

stinger systems (9.2%), then wells / excavations are 7.22%.

If the concept of clean water is relatively rural, so well / drilled wells with people in the

project area are considered to be relatively secure in terms of water for drinking. However, in

some communes such as Xuan lai and Vu Linh (Yen Binh district); Minh Xuan commune,

Luc Yen district and Thuong Bang La commune, Van Chan district, still have households

using ponds and lakes as a source of drinking water, especially in Vu Linh commune,

accounting for 22.86% of households surveyed.

iv. Waste treatment

- In Yen Binh district: Since 2015 domestic waste in Yen Binh town and a number of

production and business establishments of the town are collected and transported to Nam

Thanh Environment and Energy Joint Stock Company for processing. . In Thac Ba town,

garbage is collected and transported for disposal at Vinh Kien landfill. Garbage at medical

facilities has been collected and treated by separate incinerators at the medical center. The

communes in rural areas do not have a waste collection team yet, but the amount of waste in

rural areas is mainly organic waste, most families have dug from 01 to 02 burial sites,

environmental hygiene.

- In Tran Yen district: A sanitary waste treatment area in Bao A commune is operated to treat

waste with an average of 18m3 / day. Garbage is classified separately from ordinary waste

and hazardous waste, then concentrated at the specified location to wait for treatment in

accordance with the plan of burning or burying. However, this waste treatment area can only

meet Co Phuc town and some neighboring communes. Most communes in the district do not

have environmental sanitation teams, have not been able to arrange waste collection areas,

mainly due to households being treated by burning or buried at home gardens.

The district health center has been invested to build a system for treating medical waste (both

solid waste and liquid waste) to ensure environmental standards. 100% of medical waste in

the district is collected and disposed at district health centers.

- In Van Yen district: Waste in Mau A town is collected by the Urban Environmental Hygiene

Team. Waste is collected after being collected to Mau A town landfill for burial. The amount

of waste collected in the town is about 70%, the rest is collected and treated in household

garbage pits in the form of burning and burial.

For domestic waste in rural areas, 23 out of 26 communes have established waste collection

teams operating in the center of the commune. Waste is collected and gathered to the

concentrated landfill of the commune, then sorted and processed in the form of burning and

burial. In addition, in residential and village areas, domestic waste is treated on-site with

household garbage. Medical waste is collected and treated separately at district health centers.

- In Luc Yen district: Garbage of Yen The town and a part of households on the main roads in

the neighboring communes are collected and transported to the central garbage disposal area

in Lieu Do commune; Waste is treated by landfilling and spraying chemicals to help

decompose and prevent flies and mosquitoes. The main roads in Yen The town are collected

daily, ensuring environmental hygiene. However, because there is no dedicated vehicle for

transportation, the collection is still limited. Households living in small alleys have not been

collected. Garbage in communes is mostly handled by households on their own by burning

and burying. Medical waste is collected and treated separately at district health centers.

81

- In Van Chan district: The district has 01 garbage dump concentrated in Son Thinh

commune, treating waste for 03 communes and townships: Nong truong Nghia Lo town, Son

Thinh commune, Dong Khe commune. The treatment of domestic waste has not yet been

classified at the source, only collected daily and transported to the garbage. Waste in the

remaining communes is mostly handled by households on their own by burning and burying.

117,782 KVA; 100% of communes and towns have access to the

national electricity grid, 99% of households use electricity, of

which 80% use electricity to ensure quality. Currently, some 0.4

KV electric transmission lines made by the people themselves have

not met the technical standards, so the quality of electricity used is

low.

2 Tran Yen

District

Power supply for Tran Yen district area is taken from Yen Bai

E12.1 110kV substation, through the medium voltage line

including DZ 35kV: 372E12-1 roads; 374E12-1; Road ĐZ 10kV:

971T12-3.100% of communes with national power grid, the rate

of households using national grid of good quality reaches 99.6%.

b) Physical and intangible cultural properties

There is no cultural or archaeological site within the construction scope of the subproject.

Therefore, the impact of the project on physical and intangible cultural assets is not available.

c) Regarding security work

Security is well maintained and implemented, the situation of political security, social order

and safety in the communes is kept stable, there are no passive and unexpected cases. Not to

form a hot spot for political security, there are no complaints and petitions for people

overcoming levels and complicated and pressing cases among the people. Permanent

residence management is interested in directing. Police town / commune regularly organize

accommodation and temporary checks to ensure the security situation in the locality. Workers

and engineers of TDA from other places to work will be registered for temporary residence in

the locality to ensure good security work, avoid disorder and disturb the lives of local people.

d) Regarding the current situation of using fertilizers and plant protection drugs

The subproject is implemented in 14 communes of 5 districts with similar natural and socio-

economic conditions, agricultural production activities mainly include rice, maize cultivation

and crops divided. 2 main crops in the year, the harvest from February to June, the crop from

August to December, in addition, some communes have a very large area of production forest

land, planting valuable perennial industrial crops. High economy such as Tea, Que, and Fruit

trees also bring stable income for people.

The use of plant protection drugs (pesticides) to control pests and diseases of crop protection

is also an important factor in production development. In recent years, due to intensive

farming, increasing area, changing plant structure, the situation of pests and diseases has been

more complicated, so the popular method of agricultural production when crops are exported.

Currently, pests and diseases are using pesticides. Pesticides are used by people with

unscientific doses and at the right time, which can have unpredictable consequences for plants

as well as for public health. Besides, it can pollute water sources, pollute the living

environment and break down the field ecosystem. However, for the subproject communes, the

situation of using well-controlled pesticides by the people who do agricultural production in

addition to the market is still self-sufficient for their own lives so pesticides are used less. The

average amount of pesticide used in subproject communes is about 0.9kg /ha. The amount of

fertilizer used in the subproject area is met enough to meet the nutritional requirements

according to the temporary norms of the district agricultural extension center. The main types

83

of fertilizer used include Urea, Lan Supe, Potassium Chloride with an amount of 250kg /ha,

515kg /ha, 120kg /ha respectively.

communes in the subproject.

In general, the economy of the communes in the beneficiary area of the project still maintains

a good growth rate in most sectors. Agricultural and forestry production continued to achieve

positive results. Agriculture and forestry still accounts for a high proportion of the commune's

economic structure: Thuong Bang La and Vu Linh, Tich Coc accounts for more than 90% of

the commune's economic proportion. Besides, industry and handicrafts are also developing in

some communes such as Yen Phu, An Thinh ... The communes continue to implement well

the work of hunger elimination and poverty reduction and create jobs for workers. The

education and training work continues to be strengthened, the level of teachers is gradually

standardized; well maintain the education universalization. Cultural, artistic, physical training

and sports activities have been exciting and social security has been maintained, contributing

to the socio-economic stability of communes in the year and tending to develop steadily and

firmly, creating a premise to successfully achieve the socio-economic development objectives

and tasks of the next year and the following years. However, in addition to the achieved

results, there are still some shortcomings and limitations that need to be overcome: The

people's awareness of environmental protection is still limited, people's waste is not yet

collected. Thoroughly collect. The rate of poor households in communes is still high: typically

in Muong Lai commune 32.6%, Xuan Lai 44.14%, Tich Coc 39.96% ...

4.5 Summary of survey results of subproject communes

Based on the basic design, the Consultant and staff of PMUs and cadastral officers in 14

communes list the households affected by each project in each commune. On the basis of the

list of AHs provided by local authorities, the consultant consulted 100% of AHs (38

households) directly and indirectly (in which 07 households are expected to permanently lose

part of production land); 679 households are located in beneficiary areas for interview with

questionnaires. Of the 679 households interviewed, 153 were answered by women. Cases of

in-depth interviews and group discussions were selected from the list of affected households

and key informants at the PMU of Yen Bai Province, for agricultural and rural development

projects set at local people's committees of communes and departments. Each group

discussion is from 6-8 people.

The consultant has set up a research team consisting of 6 key experts (including a sub-team in

charge of the social evaluation of the subproject) and field survey experts to perform the

tasks. From the approach to household livelihood resources, this section will analyze the

socio-economic characteristics of the surveyed households by resources: human capital

(demographics and labor, education, occupation health), capital of natural resources

(production land: agricultural land, forestry land and aquaculture land, land use rights),

physical capital (houses, properties used for living and property used for production and

business), financial capital (income, living standards change, poverty, borrowing), and social

capital (community relations, relatives, government and their support ) and consider the

impact factors including potential project impacts. Summary of survey results is detailed in

the following sections:

4.5.1 Demography

The average number of people in a household in the project area is 3.13, of which Yen Binh is

3.66 people; Van Yen district has 2.49 people; Luc Yen district is 3.22 people; Tran Yen

district is 2.64 people and Van Chan district is 3.34 people. According to gender, male

The survey results showed that the percentage of households with 3 to 4 people accounted for

the highest percentage of 56.41%, followed by households with 1 to 2 people, accounting for

34.32%. The highest proportion of female-headed households is in households with 1 to 2

people (accounting for 22.47%). Households with 3 to 4 people and 5 to 8 people have male

household heads of 90.70% and 87.30% of women account for 9.30% and 12.70%. In general,

in the surveyed households, male headed households are still predominant and account for the

majority.

4.5.2 Occupation

In the main occupational structure of family members involved in labor and income in the

survey sample of the project area, the agriculture-forestry-fishery sector accounted for the

highest rate of 58.47%; secondly, students and students accounted for 20.15%; the proportion

of people doing business / services accounts for 2.07%, handicraft and handicraft accounts for

0.24%, workers account for 2.50%, the proportion of officials and employees accounts for

1.55%, retirement accounted for 1.04%, working as hired laborers was 11.49%; The rest is the

rate of labor loss, housework, joblessness and inadequacy that is lower than 2% for each

category. Thus agro-forestry-fishery is the key field in the socio-economy of the project area,

where the majority of the labor force is concentrated.

4.5.3 Health

About 86.30% of households surveyed in the past month were sick. This is a relatively high

index and worrisome about the health status of people in the project area compared to the

general situation of health status and health care conditions are getting better today. There are

no major differences in illnesses between the surveyed communes as well as between the rich

and poor income groups, mainly colds and respiratory diseases. The rate of illness in Vu Linh

commune, Tich Coc commune, Xuan Ai commune, Muong Lai commune is quite high up to

96

100% in the past 12 months.

We found that 96.91% of the respondents answered that they have participated in health

insurance, which indicates that health insurance in households has been more concerned than

in previous years. In terms of income groups, the poverty group has the highest proportion of

people participating in health insurance due to the support in paying health insurance ...

4.5.4 Water supply

Bath water source: Most of the households in the project area surveyed by domestic bathing

water use dug wells / drills 92.78%, the percentage of households using lake and river water is

5.6%, number households using clean water account for a small proportion of 1.77%.

In rural conditions, water used for bathing activities is considered hygienic from sources such

as dug wells/drilled wells. Therefore, it is necessary to keep water, not to lose water in

reservoirs to meet people's needs.

Drinking water source: As with drinking water, the source of drinking water for the people in

the communes in the surveyed area is 92.78% using dug wells, the percentage of households

using pond water lakes, rivers and streams are 5.74%, the rest is using clean water, making up

a small proportion of 1.62%. If the concept of clean water is relatively in rural areas, so wells

digging with people. The project area is considered to be relatively secure in terms of water

for drinking. However, in some communes such as Xuan lai and Vu Linh (Yen Binh district);

Minh Xuan commune, Luc Yen district and Thuong Bang La commune. Van Chan district,

still have households using pond and water water for drinking water; in which surveyed

households in Vu Linh commune account for the highest percentage (22.86%).

Water source for production: The water system for production for the households in the

project area mainly accounts for 86.58%; The number of households using water from ponds,

lakes, rivers and dug wells accounts for <10%. Besides, no household uses water from clean

water, irrigation systems and rainwater.

Thus, in the surveyed sub-project communes, irrigation ponds play a huge role in the

production sector of the people. Therefore, keeping water in the water shortage season is a

very meaningful job for people in the project area.

4.5.5 Housing hygiene conditions

According to survey results: 18.85% of households live in permanent housing; 32.55% of

households in semi-permanent houses; 46.98% of households live in wooden houses, roofing

and 1.62% of households in temporary houses. Housing is one of the important criteria to

assess people's living standards. The above figures reflect a high percentage of households

with wooden houses and roofing houses, showing that the living conditions of households in

the project area are still very difficult. People use a lot of wooden houses due to the custom of

the people in the mountainous communes, the communes are ethnic minorities.

In recent years together with the National Target Program on new rural construction, there

have been certain achievements to change the face of rural and home countries, with a great

emphasis on landscape protection and agricultural environmental sanitation, village. This is

seen more clearly in the surveyed area where 50.52% of households have a septic tank /semi-

septic tank, 21.94% of households use a two-compartment toilet and 27.10% use a simple

toilet. However, there are still 0.44% of households without toilets.

Data in Table 14 also show that households belonging to different groups need different

births. In better-off groups, more septic and semi-septic toilets are used than poor households

and a few households still do not have toilets in poor households.

According to localities, self-assessment of the average living standard has the highest rate,

typically 75% in Yen Hop commune; Thuong Bang La commune of Van Chan district is

69.57%. At the poverty level, only Minh Xuan commune in Luc Yen district is occupied with

a high rate of 37.04% with Phu Nham commune of Van Chan district and Yen Hop commune

of Van Yen district only 4.55%.

highest poverty and living standards still belong to the poor households and female headed

households. So in the hope of the project contributing to improving the lives of women

because they are vulnerable.

4.5.7 Some issues of social security

Borrowing: a common and common situation in living activities of rural communities.

Surveying the population in the project area shows a reality of the situation of borrowing

through data in Table 4.16. Accordingly, loans from households are mainly from the Bank for

102

Agriculture and Rural Development; In Thuong Bang La commune of Van Chan district,

there is a rate of 19.57% on the contrary to Thac Ba commune in Yen Binh district, almost

households do not borrow, and few borrow from banks or funds. For households in the project

area, the households do not dare to invest large when production conditions, making a living

does not guarantee high profits to pay capital and interest. Therefore, investment in irrigation

and agricultural infrastructure for production development will help people feel secure to

borrow.

Table 4.17 shows the different loan purposes of families who borrow. People use loans to

spend the most for the purpose of farming and agricultural production. Typically, Xuan Lai

commune in Yen Binh district has a ratio of 36.84% for people to grow crops and livestock.

An Thinh commune, Van Yen district is mainly used for forestry development (Cinnamon

cultivation) with a high rate of 20%. This shows that these are the goals that people in the

project area are interested in and need to borrow money to implement. Besides, there are some

purposes such as investment in trading / services, education, home repair, medical treatment

... with very low rate (<10%).

When examining the proportion of the purpose of borrowing money in each commune, the

survey data shows that the purpose of “investment loans for livestock and agricultural

production” accounts for the highest proportion. This is easily explained by the fact that

people still focus on production development and life stabilization.

- Social security: In every human life there are times when there are risks or difficulties that

people need the help of other people (or other organizations) to overcome. Survey of

difficulties / risks that need material support (Chart) shows that people rely heavily on support

from their parents on both sides, coming from siblings, children and friends, neighbors,

authorities / organizations. .... This shows that in addition to relying on material support from

parents and children, unions and authorities also play an important role in helping people

overcome difficulties in life to develop production.

4.5.8 Ethnic minorities

Among the 14 communes in the project area, there are 6 different ethnic minority groups,

including: Tay, Cao Lan, Muong. Kho-Me, Dao and Thai. Among them, Tay people are the

largest with 251 households out of 632 surveyed households. Most ethnic households are

people living for a long time in the area of 14 communes in the project area. The number of

EM people in the surveyed households is shown in Table 4.19 below.

The results of consultations and damage surveys show that there are no EM households

affected by the land acquisition as well as the absence of any EM groups that are adversely

affected by the project implementation. The results of consultations with ethnic minority

groups in communes show that they agree with the implementation of the subproject and they

are aware of the project will bring many benefits for economic development in the locality.

The income of the majority of ethnic minority households depends on agricultural production

activities but they are facing many difficulties in water resources for production. They said

that the potential reservoir group (16 reservoirs) to be repaired and upgraded will help to have

more water for production, thereby helping to increase household economy. They also said

that the implementation of the project may cause adverse impacts on fishing activities of some

households engaged in aquaculture activities during the construction period. However, people

think that these impacts do not significantly affect communities and households.

4.5.9 Gender characteristics in the subproject area

Women are important subjects of the project, belonging to both the affected group and the

beneficiaries. Therefore, it is necessary to understand the gender aspects of the project and the

different impacts on women to maximize the benefits of the project. Gender analysis and

gender action plan are included in the Annex of the social assessment report (SA).

Survey results and community consultations show that there is no significant discrimination

between men and women in learning medical examination and treatment, income, making

decisions on important family issues. Most activities were attended by both men and women,

accounting for 95.68% (see Table 4.20).

However, employment opportunities and the ability to adapt to career changes are now an

obstacle for women, especially women working in agriculture over the age of 40. Project

implementation may cause a The number of risks needs to be noted, such as the employment

of women whose agricultural land is revoked: the fact that women currently participate

mainly in agricultural production, the implementation of the project will affect agricultural

land and That increases the risk of underemployment for women. This can be mitigated if

local women, especially women in affected households are given opportunities to participate

in vocational training programs, capacity building and enhanced communication campaigns,

107

awareness of sanitation. traffic safety or prevention of social evils ...; prioritizing the

allocation of suitable jobs for women when implementing project items will also reduce

unemployment for women and create an opportunity to increase income for affected

households.

Arranging jobs for women and opportunities is also a potential risk for them to face problems

that are not just safety and at risk of abuse. A number of other issues also have potential risks

such as traffic safety issues, discrimination in employment and jobs that do not require skills

from contractors of the project ... should be noted. Gender issues should be considered a risk

and will be detailed in the Gender Action Plan at the subproject SA report.

4.6 Site-specific receptors

The subproject is carried out in 14 communes /towns scattered across 5 districts of Yen Bai

province, in the process of extensive deployment will have an impact on the environment and

people's livelihood activities, local population. The work should be noted by the specific

impact on the sensitive points of the reservoir area when repairing and improving dam safety

is presented in the table below.

109

CHAPTER V. ENVIRONMENTAL AND SOCIAL IMPACT ASSESSMENT

5.1 Types and scale of impacts

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 16 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, solidified,

rehabilitated will increase the safety for people and property in bad weather conditions.

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 impacts are negative, temporary, localized 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 activities1.

110

Potential negative environmental and social impacts are also broken down by types such as

direct, Indirect, short-term, long-term and cumulative impacts.

Directimpacts: The direct impacts occur through the direct interaction of a subproject activity

with environmental and social or economic components.

Indirect impacts: The indirect impacts on the environment and society that are not direct

results of the Subproject, which is often created later or as a result of a real complex impact.

Indirect effects are also known as secondary effects or even tertiary effects.

Cumulative impacts: the impacts that occur as a result of a combination of the Subproject

with other projects that cause associated impacts. These impacts occur when the incremental

impact of the Subproject is combined with the cumulative effects of past, present, or future

projects that have the potential for predictability.

Temporary impacts: the impacts that occur during the construction or within a short period of

time after the construction.

Long-term impacts: the impacts that arise during the construction but most of the results

appear in the operational phase and can last for decades.

5.2 Positive environment and social impacts

The subproject will improve the efficiency of 16 reservoirs and will bring positive

environmental and socio-economic impacts to local communities as follows:

5.2.1 Social impacts

The Subproject after being completed will bring benefits to the community and local

authorities, namely, dam body and dam slope to be rehabilitated will ensure safety for

downstream areas in rainy seasons, limit leakage and loss of water, ensure the flow of

irrigation water for agricultural production in the downstream in accordance to the local

government's production regulation plan, increase productivity and agricultural productivity

as well as crop yields and aquaculture development. The works to be rehabilitated will ensure

the stable supply for paddy and vegetable areas throughout the year in the downstream of 14

communes. They supply water for aquaculture area and limit negative impacts on the

environment, landscapes of the reservoir areas and downstream. They stabilize the

aquaculture water surface non-agricultural production and business, increase income and

living standard as well as create more jobs and income, especially for unskilled and seasonal

workers.

Increase in the irrigated area

Investing in repairing and solidifying construction items in 16 dams will stabilize the active

irrigation water, increase the cultivated area of winter-spring crop from 660 hectares to 769

hectares (up 109 hectares), increase the sown area, planting summer-autumn crop from 612 ha

to 732 ha (increasing 120 ha), taking initiative in agricultural cultivation plan, planting

season, and seedling structure for downstream areas, gradually contributing to perfecting the

basic infrastructure improving living standards of people in difficult areas.

Impact on management capacity operation of irrigation systems

The second year DRSIP project will improve the safety of the reservoirs and help the local

authorities in the project area to develop long-term rural development strategies and scenarios,

taking into account climate change scenarios and realizing activities to implement the national

target program on climate change mitigation and adaptation, the Water Resources

Development Strategy up to 2020 with a vision to 2050, the National Strategy for Rural Clean

Water Supply and Sanitation up to 2020, the Program on Socio-economic Development in

111

Mountainous Areas up to 2020, and the National Target Program for Building New Rural

Areas.

5.2.2 Environment impacts

(a) Impact on air quality and microclimate condition

The rehabilitation of the reservoir construction works will affect the air environment at the

construction phase but in small space and impacts are local and intermittent. When the

reservoirs are operated, they will have positive impacts on the change of some meteorological

factors in the areas. For example, the stabilization of water surface will change the

microclimate condition of each reservoir area and the moisture which is related to the

continental dry, nature of the climate in dry seasons. In addition, in the operation phase, the

Subproject will increase the stability of water resources and safety for the works and the dam

downstream.

(b) Impact on the landscapes

At present, 16 reservoirs being exploited have spillways but some draining culverts are

leaked, the slopes are not concreted and there are not roads for management and operation of

the works. As proposed by the Design Consultant, to ensure the safety of the dam body,

draining culverts, it needs reinforcement, replacement and concretion of the works to ensure

water storage avoid water loss and create convenience for regulating water for production and

operation of the reservoirs, which will ensure the development conditions for coastal

vegetation communities, creating landscapes around reservoirs and local traffic.

The repairing, solidifying the management roads of 16 reservoirs will create a new look for

the reservoir landscape and the surrounding area. The reservoir area will be beautiful, modern

and safe.

(c) Impact on the ecosystem

After the construction works in 16 reservoirs are complete, the stable flows of water and

irrigation will contribute to the development of aquatic and plant ecosystems in the reservoirs

and the downstream areas. There will be continuously and positive impacts on the ecosystem

for long time, which help diversify and enrich the flora and the fauna in the subproject area.

(d) Impact on groundwater

The completion of the construction works in 16 reservoirs will stabilize the water levels and

increase the water level in reservoirs and ponds, which is higher than the downstream areas.

Therefore, after the reservoirs are operated, the downstream water level is always maintained

year round to meet the demand for water for daily life and cultivation of local people.

5.3 Potential negative environmental and social impacts

5.3.1. Impact in the preparation phase of construction

Activities in the preparation phase include: Land acquisition, tree cutting, site preparation for

disposal sites, material yards, construction of camps, removal of organic layers, transport of

waste soil, etc. During the construction preparation phase, negative impacts on the potential

environment include:

a) Impact of land acquisition:

According to preliminary inventory results (IOL) in November 2017 and updated in October

2018, a total of 38 households and 06 CPCs are affected on land and assets on land.

Specifically:

- Permanent effects:

112

+ Permanent impact on land: There are 600m2 of production forest land of 02 households

currently growing Que (land has been granted land use right certificates) and 18,444m2 of

public land (land in the safety corridor) dam) of 06 CPCs in the subproject area that currently

provide people with bamboo, acacia, cassava, orange, longan and litchi.

+ Influence on crops and crops: Land acquisition for construction of subproject items will

affect 86,026 m2 of plantation area. trees (bamboo, tea, cinnamon, acacia, eucalyptus),

cassava, longan, litchi, orange) of 37 households, of which 30 households are affected by

trees on land owned by households (among these Ahs, there are 4 households who are

affected by trees on their land) They own and are affected on the land managed by the

Commune People's Committee) and 07 households are only affected by trees on the land

managed by the Commune People's Committee.

- Temporary effects:

+ Temporary acquisition of 67,442 m2 of agricultural production land of 29 households. In

which: i) Production forest land area is 66,982 m2 of 28 households currently growing types

of Tea, Que, Keo, Eucalyptus ...; ii) The area of annual crop land is 460 m2 of 01 household,

at the time of survey this land area does not grow trees and crops, only wild grass plants grow

naturally.

+ No household is affected by construction water cut due to the construction process, the

Project Management Board will inform local authorities and water users about the water cut

plan (for example, time limit to use water) so that local people can actively produce. At the

same time, temporary dykes must be built to divert water so that no household will be affected

by dehydration during construction. In case of no mitigation, households will be supported in

accordance with the approved RPF.

Note: Out of 38 Ahs, there are 30 AHs from 02 types of land (both affected with land and

trees) and 08 AHs of 01 type (including 07 households who only affected AHs due to

cultivation on the land of the People's Committee Commune management and 01 household

are only temporarily affected on land for annual crops because at the time of the survey on

land without planting trees. only weeds).

Among 38 Ahs, there are 15 vulnerable households in which: 1 poor household has single

women headed households (with dependents) and 14 households are ethnic minorities.

There is no affected household business, no AHs about houses, architectural objects. There

are no severely affected households by the subproject. In addition, the subproject does not

affect the cultural heritage, public works in the area. Summary of the impact of the subproject

is presented in the table below.

Source: Survey and summary data. November 2017 and updated in October 2018

Area of land occupied on a total of 16 works is not large, including forestry land, agricultural

land, production land, and no residential land. In fact, some households around the lake/dam

area have a large area of land, therefore, the area of land acquired or occupied temporarily

accounts for a small proportion, much affecting daily life and manufacturing.

Thus, the land acquisition is considered to have negligible impact on production and people's

lives, because most of the acquired land area is production forest land, 21.3% of the total area

land reclaimed under public land. This impact will be overcome by the full implementation of

compensation and support regulations in the Subproject's Resettlement Action Plan.

b) Impact of UXO risk

114

Landmines were discovered throughout Vietnam due to the war and there were casualties

caused by accidents involving the persecution of explosives. According to the initial

assessment and survey. The subproject area has no UXO after the war, but to minimize risks,

the subproject owner should contact the demining authorities to provide confirming safety of

mines and ERW before construction.

c) Land clearance activity

The land clearance activities in this period are mainly carried out by the affected households

themselves on the area of agricultural and forestry land that is temporarily or permanently

acquired. Therefore, some waste from this luminescence will be generated. These activities

will also affect the fauna of the subproject area due to the loss of habitats and changes in the

ecological landscape.

d) Impacts due to geological drilling

Before designing the plan, the investment project consultant unit (FS) conducted geological

exploration, each reservoir carried out 5 drilling holes including: at the 3-pit dam site, each

hole was deep about 60m; The heart of the drilling hole is 1 hole 25m deep and along the

spillway, 1 hole is 10m deep. This process will potentially put impurities affecting the quality

of underground water.

5.3.2. Impact during construction phase

5.3.2.1. Construction activities and sources of impact

Construction activities

- Clearing, leveling the ground

- Construction of sewer repair

- Construction of upgrading upstream roofs and downstream dams

- Repair and construction spill

- Repair and construction of road management

- Building operator

Source of impact related to waste

Sources of solid waste generation

- Waste from luminescent activities, site preparation

- Domestic waste of construction workers at construction sites;

- Waste from construction materials at construction sites: spilled rock, cement bags ...

Source of liquid waste generation

- Water for washing stones, sand and gravel

- Waste grease

- Domestic wastewater of construction workers at construction sites and residential areas.

Source of emissions

- Excavation and leveling work

- Making road construction, road management

- Exploiting, transporting and loading and unloading materials

- Mixing concrete and mortar

- Operation of vehicle and transport system;

- Activities of construction equipment such as bulldozers, excavators, compactors, trucks, ...

Impact sources are not related to waste

- Landslides due to earth excavation on steep terrain

- Noise and vibration due to construction activities

- Risk of fire and explosion incidents

5.3.2.2 Impacts in construction phase

118

(a) Social impact

➢ Community health and safety

Health risks for workers and people may be due to a number of reasons and sources as

follows: (i) waste and domestic waste generated from camps and construction sites but not

managed properly, physical; (ii) Water and wastewater deposition creates reproductive

environment for flies, mosquitoes and infectious diseases that can be triggered by

environmental pollution; (iii) Hazardous materials such as chemical termites and oils, if not

properly managed, can directly go into water sources and cause harms to the users' health; (iv)

Local people living along transport routes and workers at construction sites may be affected

by dust, noise and vibration.

During the construction process, at the construction sites, mobilizing workers to work is

potentially at risk of infectious diseases and increased disease vectors that may pose a health

threat to workers and the local population, direction. Infectious diseases create a public health

threat often related to activities such as hygiene and low living conditions, sexually

transmitted diseases and vectors. The most worrisome infectious diseases in the construction

phase due to labor migration are sexually transmitted diseases such as HIV/AIDS. Gonorrhea,

syphilis. ...

In fact, the time to implement the subproject within 12 months of intermittent construction,

the construction site is scattered in 16 locations and the number of officials and workers from

other localities reaches about 15 workers / 01 project (mainly engineers and skilled workers

for simple jobs hiring local workers), there are many scattered items, good security and

disease control situation in the area; In addition to the area in which workers are hired, people

have clean conditions, all toilets are required to meet QCVN 01: 2011 / BYT on hygienic

latrine standards; limiting conditions for spreading infectious diseases caused by flies,

mosquitoes and insects so the impact is assessed as medium.

➢ Risk of gender violence and child labor use

The construction process will attract free migrants to the construction site, which could

potentially pose a risk of gender violence, child labor use, sexual abuse and harassment. This

impact is controlled by the construction contractor and specified in a Gender Action Plan.

However, to minimize and limit impacts, the Investor will closely coordinate with local

authorities to assess the impact level to have appropriate management measures.

➢ Accident risks and incidents

Work accidents. Work accidents can occur in any category during construction.

Fire, explosion and fuel leakage. Fire and explosion may occur in the case of transporting and

storing fuel, or the power supply system is temporarily unsafe, causing death and property

damage during construction.

Welding: Welding creates extremely strong light and can cause serious injury to the eyes of

workers. In extreme cases, it can lead to blindness. In addition, welding can create toxic

fumes that prolonged exposure can cause chronic illness.

Drowning: During the construction process near water bodies, it is possible for workers to

take a bath and drown.

Short circuit and electric shock: Construction activities may cause short-term risks affecting

the health of workers and residents as well as their properties. Temporary power supply

system for machinery and equipment in the construction process can cause problems of

voltage, electric shock, etc, causing economic losses and labor accidents for workers.

119

In the implementation of subproject items, the construction site is mainly in the dam body, so

the problem of accidents due to working at high altitudes is unlikely.

Due to the characteristics of the work on the construction item volume is not large, the

management process, monitoring the implementation of strict environmental safety policies

should impact from risks and incidents are assessed at an average level.

➢ Impact on traffic safety and infrastructure

The process of transporting materials will go through concrete roads in villages/communes,

in-field roads with small load capacity, when moving larger vehicles will damage and damage

these roads, causing difficulties for people to travel, activities, production ... as well as the risk

of traffic insecurity. The increase in transportation means will increase traffic safety risks for

people. In particular, this route passes through residential areas of 14 communes, where there

are schools, markets and intra-field traffic routes. However, the construction work is not

continuous for 12 months and this impact is manageable, so it is assessed at an average level.

About 31,926 turns of transport via construction routes from the district center to the

construction sites may cause damage to the existing route.

In particular, the route through the residential areas leading to the lakes may be damaged by

large vehicles. Roads through residential areas and intra-field roads are concrete roads with

small load capacity, which can be broken, crushed or collapsed, subsidence when large trucks

pass or high density of vehicles. Specifically:

– Lake Tu Do, Y Can commune, Minh Tien commune: When constructing a sudden increase

in the number of vehicles, attention should be paid to the people's roads (the road to the

auxiliary dam No. 4) with concrete people do.

– Lake Thon 26, Thuong Bang La commune Road of people living in a village of 500m long

has been hardened by concrete, so when construction is not allowed for large vehicles passing

by

The potential impacts on roads are required by the investor to the construction units with

commitment to the local on the repair and restoration of the original state if any damage

occurs during the construction process, so it is assessed as low risk.

➢ Impact due to construction water cut

The construction of dams and dams under the NWL, new and repaired drains to drain water

must lower the water level for construction to affect production and water supply for

downstream areas. However, the Investor has arranged the time for construction of dams and

sewers for water intake from September 15 to December, during this period, harvest of winter

rice crops and planting of winter crops should not affect manufacturing. In addition, there is a

plan for embankment of dykes for construction and measures to pump water to ensure

sufficient water supply for production and living in downstream areas, so the impact is

assessed at a low level.

➢ Impact of the flow of workers in the subproject area

Construction activities require about 240 workers coming from elsewhere to 16 construction

works, mainly key officials and skilled workers (some items use local labor), so will affect the

local socio-economic environment conditions as follows:

- The concentration of people, with poor sanitation conditions in the campsite will generate a

number of epidemics, social diseases ... affecting the health of workers and people in the area.

- Workers from other places can disturb the lifestyle of the local people.

120

- There may be some bad objects in the locality stealing equipment and construction materials

causing instability, affecting the progress of project implementation.

- Potential conflicts between workers and local communities because of cultural and

behavioral differences.

- Conflict on the need to use local service infrastructure such as electricity and water supply

and transportation systems, leading to lack of electricity and water supply and traffic

congestion for the area.

Due to the scattered 16 projects throughout the province, the number of people from other

localities working at each project during the implementation of the subproject is small, so the

above issues can be managed. The impact is low.

➢ Impact on aquaculture, tourism activities, navigation:

Because there are no tourist activities and navigation in the reservoir area. The lowering of

lake water level for construction also affects households who are renting the reservoir area for

aquaculture; however, due to the small number of reservoirs for aquaculture purpose (Thon

26, Khe Vai) and the investor will have prior notice of the schedule and the expected time of

construction so that people can plan fish harvesting in the lake, so The effect is negligible.

➢ Detecting antiques

Excavation and construction activities can find physical cultural heritage under the ground.

However, these facilities are located along the lake with long-term cultivation activities.

These areas have been studied and confirmed that they are not archaeological sites, so the

probability of finding artifacts, physical cultural heritage is low.

➢ Cultural and historical relics

There are no cultural and historical relics in the project area

➢ Impact on the regional landscape:

The gathering of large quantities of construction materials and equipment will cause changes

in the land surface, reducing the coverage of vegetation, creating protrusions due to

excavation of the landfill area and soil mines affect the natural landscape of the area. These

impacts are not serious and will be restored after completion of the subproject.

(b) Environmental impacts

At the construction stage, construction activities have the strongest impact on the

environment, including material exploitation activities at land mines, transport of materials

from supply sites to construction sites and transport of rock and soil, redundancy to the

landfill. The volume of materials in the construction phase is summarized in Table 5.4.

i) Impact on the air environment:

➢ Impact on air environment due to dust and emissions:

- Dust and emissions from clearance activities, weathering

+ Dust and exhaust gas due to excavation and weathering

Excavation, unloading and loading and unloading of soil and stones from weathering and

demolition activities will increase the amount of dust. According to WHO's rapid assessment,

the amount of dust generated by the peeling process, digging soil, and leveling the ground is

swept up by 100g/m3; Thus, the total amount of dust generated during the weathering and

demolition phase was about 7,058 kg at 16 sites.

According to the document "Air pollution and emission treatment of Science and Technology

Publishing House", emissions generated when consuming 1 ton of fuel of excavator are 0.78

kg of dust (soot smoke); 4.16 kg CxHy; 7.8 kg SO2; 13.01 kg NOx and 20.81 kg CO.

Since then, the volume and load of dust and exhaust emissions are calculated in detail at the

construction sites of each lake as follows:

Because the dust emission source spreads over a large area, it is possible to apply the surface

source diffusion model to determine the concentration of pollutants in different time periods

at the construction area according to the following formula:

C = Es x L (1 - e-ut / L) / (u x H) (3.1)

(Source: Air environment. Pham Ngoc Dang- Hanoi University of Construction)

Where:

u: Average wind speed blowing perpendicular to one edge of the box, averaging in the project

area: u = 1.5m/s;

H: Disturbance height (m), choose H = 5 m;

L. W: Length, width of air box: L = 50m, W = 25m (based on leveling area at a time);

Es: Polluted emissions calculated per unit area, mg/m2.s;

Es = A / (L x W x 3600) = Load (kg/h) x 106 / (L x W x 3600)

= 1.5 x 106 / (500 x 25 x 3600) = 0.041 (mg/m2.s)

t: Calculation time (h).

Emission concentration of dust at the construction site with the assumption of weather in the

dry season is as follows:

Table 5. 6: Concentration of dust in the process of leveling and loading soil

Average concentration. mg/m3 QCVN 05:2013/BTNMT

(mg/m3) 1h 2h 3h 4h

0.196 0.345 0.525 0.686 0.3

With an average wind speed of 1.5 m/s, we can calculate the concentration of polluted gases

by leveling machines as follows:

Table 5. 7: Concentration of gases due to leveling and loading

Concentration. mg/m3 QCVN 05:2013/BTNMT

Muội khói 0.135 0.136 0.136 0.136 -

According to the above calculation results, diffused dust and exhaust gas content from the soil

construction process (stripping weathered structure demolition) of the lakes is still within the

allowable limits of QCVN 05: 2013/BTNMT. In large space conditions, the construction time

is not much about 1 month affecting mainly the workers at the construction site, so the impact

is assessed at an average level.

+ Dust and emissions due to transporting weathered soil

According to Nguyen Khac Cuong's environmental curriculum in construction (2007), dust

from transporting 1m3 of soil will generate dust of about 0.75 kg/m3, of which suspended

dust (TSP) accounts for about 10% of the price. The corresponding dust dispersion value is

0.0019 kg / hour. Dust generated by transporting weathered soil to waste dumps takes about 1

month, affecting mainly workers and local people.

To calculate the average concentration of pollutants generated by soil transport, the stone

applies Sutton's transformation model. The calculation formula of this model is as follows:

C = 0.8xE {exp [- (z + h) 2 / 2σz2] + exp [- (z-h) 2 / 2σz2]} / (σz.u) (mg/m3) (3.2)

(Source: According to Air Chief, US EPA, 1995).

Where:

C: Air pollutant concentration (mg/m3)

z: Height of calculation point. z = 1.5

σz: Diffusion coefficient in the z direction (m) is a function of the x-distance by the wind

direction, determined by the Slade formula: σz = 0.53 * x0.73

x: Distance (coordinates) of points calculated compared to waste sources, calculated by wind

direction

u: Average wind speed (2m/s in Yen Bai area)

h: Height of the vehicle compared to the surrounding ground (m)

E: Pollutant load from waste source (mg/ms).

Assume 8 hours of work everyday. Airborne dust concentrations are as follows:

Table 5. 8: Dust concentration from transporting weathered soil


(mg/m3) 5m 10m 20m 40m 45m 50m

0.382 0.192 0.085 0.041 0.038 0.031 0.3

Activities to transport excess rock and soil to the disposal site, leveling the ground to prepare

for construction will increase the total amount of dust, the amount of dust (soot) will be about

132 kg out of 16 construction sites. This amount of dust corresponds to the rate of soil and

rock dumping.

According to the curriculum of Air pollution and emission treatment - KH & KT Publishing

126

House, 2001: Gas emission coefficient: SO2 = 1.28 g / km; NOx = 1.02g / km; CO = 2.57g /

km. Amount of dust calculated: 0.47g of dust generated / km x 2 km (average distance from

land acquisition point to disposal site x 15,125 car shifts)

Thus, the result of the amount of emissions in the transport process is as follows

The concentration of toxic gases generated by the process of transporting weathered soil is

low, being within the allowable limits of QCVN 05: 2013 / BTNMT

Trucks transporting waste from construction works, using diesel engines to operate will

generate smoke containing air polluting components including: smoke black (dust), SO2,

NOx, CO, Volatile organic compounds (VOCs), ... Emissions affect workers and people

living near the construction area insignificantly, plus the construction equipment inspection is

carried out often. so the impact is assessed as medium.

- Dust and exhaust from transporting construction materials

During the construction phase, similar to the calculation in the previous section, the amount of

dust increased by 86,594 tons (of which the volume of dust generated by excavation,

embankment and transport of embankment was 68,544 tons and the volume of dust generated

by transporting. Material is 18,050 tons) is presented in the following table 5.12.

+ Dust and waste generated during earthworks

With the above calculation results, applying the formula (3.1), we calculated the dust

concentration from the earthworks with the assumption of construction in the dry season as

follows:

Table 5. 12. Concentration of dust during ground leveling and excavation


(mg/m3) 1h 2h 3h 4h

0.118 0.151 0.223 0.287 0.3

Concentration of polluted gases caused by earthworks during construction with an average

wind speed of 1.5 m/s as follows:

Table 5. 13: Concentration of gases by leveling and loading

Emission Concentration. mg/m3 QCVN 05:2013/BTNMT

(mg/m3) 1h 2h 3h 4h

SO2 0.077 0.158 0.246 0.252 0.35

Smoke 0.146 0.151 0.152 0.148 -

With an average construction time of about 10 months, the average amount of dust generated is about

18kg /day/project. The effects of dust on the air environment are as follows: In normal

weather conditions, the dust and stones caused by transporting are only dispersed in the space

with a radius of about 30 m from the dust generation point, when available, wind, dry weather

can diffuse to a height of over 10 m and travel far above the wind direction of 100m, degrade

the air quality and affect the health of workers on the construction site as well as the living

community near the construction area. However, the location of the construction sites is

located in areas far from residential areas, so this impact is assessed as low.

+ Dust and waste generated during the transportation of soil and materials

Transport vehicles transporting embankment and materials to meet the needs of project

implementation are mainly 7-ton cars. During transport, these vehicles generate dust and

emissions from the pavement, from spilled materials and from the combustion of materials.

Apply the formula (3.2), assuming, every 8-hour working day. Dust concentration during

transportation is as follows:

Table 5. 14: Dust concentration from transporting soil and materials

Concentration, mg/m3 QCVN 05:2013/BTNMT

(mg/m3) 5m 10m 20m 40m 45m 50m

0.435 0.226 0.129 0.075 0.068 0.063 0.3

This problem of dust generation is localized at the material supply location and along the

transportation route, especially the problem of dust impacts will be more pronounced in the

dry season, on soil and rock roads. However, these locations are often located far away from

129

residential areas, so they affect people and social life is not much; plus transportation routes

have a large density of trees, spread across the 5 districts, so the impact is assessed as

medium.

Emission during transporting embankment soil: Based on the table of materials volume and

transport distance of materials. Characteristics of projects in the subproject area are land

mines and waste dumps located very close to the location of construction works, some lakes

with soil and waste dumps within the scope of construction. These locations are often located

far away from residential areas, so the amount of emissions during transporting embankment

and excess soil is considered low.

Emissions in the process of transporting materials: An estimated 21,317 turns of vehicles with

a loading capacity of 5- 7 tons will be moved during the intermittent construction period of 12

months on the roads of 16 construction sites to transport materials, sand, gravel, cement, steel

... on average 10-15 vehicles per day / site; Shipping distance for each trip is about 15-20 km.

According to the curriculum of Air pollution and emission treatment - KH & KT Publishing

House, 2001: Gas emission coefficient: SO2 = 1.28 g/km; NOx = 1.02g/km; CO = 2.57g/km.

The amount of dust (soot) is calculated: 0.47g of dust generated/km x 15km (average distance

from the point of supply of materials to the construction site x 21,317 cases of vehicles)

Applying the formula 3.2 of Sutton's modified model, we calculated the concentration of

emissions from the process of transporting materials as follows

The amount of emissions if exposed to high concentrations can cause respiratory and skin

diseases, in general, the particles suspended in the air can cause discomfort, reduce vision and

damage, harm to the health of workers on construction sites and people living in the

surrounding area. However, in the area with low traffic density, large space, high density of

130

trees plus strict requirements on vehicle registration and mobilization in construction, the

impact due to emissions is assessed as medium, jar.

➢ Impact on air environment due to noise

In the process of construction and repair and upgrading of construction items, many

construction machinery and equipment must be used. Noise from the operation of equipment

and machinery will affect workers and residents living near the construction area and along

the provincial and local roads. For each work item, the noise level is calculated from the

specific noise level of the machinery and equipment. The distance to assess the noise impact

on the surrounding residential area is selected from 20m-50m.

QCVN 26: 2010/BTNMT - 70 dBA (6 - 21h) for common areas

Ministry of Health standard: noise in production area: 8-hour exposure is 85 dBA

The results show that, at a distance of 20 meters from noise sources, the noise level from

vehicles is within the allowable limits of QCVN 26: 2010 / BTNMT and standards of the

Ministry of Health. However, the above calculation results show that the maximum influence

radius of noise generated from the operation of machines, equipment and vehicles is 50m

(outside this range, people are less affected and can live, work for 21 hours). Therefore, the

impact of noise only affects workers on the construction site. In addition, the project is located

far away from the residential area (outside the radius of influence), the population density in

the area is low and the density of large trees is limited, so the impact of noise is assessed at a

level, average and controllable by mitigation measures in chapter 7.

➢ Impact on air environment due to vibration

The construction process may cause ground vibration due to construction vehicles and

equipment, vibration propagation according to the soil environment, but will be greatly

reduced by distance. The level of vibration of some construction equipment is as follows:

(Source:D.J. Martin. 1980, J.F. Wiss.1974, J.F. Wiss. 1967, David A. Towers. 1995)

Actual implementation of construction, objects directly impacted on workers on the site,

should apply QCVN 27: 2016/BYT: National technical standards on vibration - Allowable

value in place work. The average value of acceleration and vibration velocity in frequency

bands must not exceed the following values.

The construction equipment of the project includes basic types such as pile driving machines,

compactors, heavy trucks, concrete mixers based on the results presented in the above table,

impact due to vibration for the current status of the subproject is negligible. The objects

affected are mainly neighboring construction works and workers. However, the construction

items of the subproject are far away from residential areas (50-500m), spacious premises,

protective equipment are regularly checked on construction sites, equipment and exam

solutions, proper work so the impact level due to low vibration.

ii) Impact on water environment:

➢ Impact on water environment due to domestic wastewater of workers:

The number of workers at each construction site is about 15 people (mainly technical staff and

skilled workers, simple items hire local workers). With the norm of domestic water supply in

rural areas in the period to 2020 is 100 liters / person / day. The amount of waste water

accounts for 80%, equivalent to 80 liters / person / day. Night, the volume of wastewater

generated is about 15 x 80 liters / person / day. The night = 1.2m3 of wastewater / day / night /

construction site. Domestic wastewater is generated from personal hygiene such as: cooking,

eating, personal hygiene ..., at 16 construction projects, due to the volume of construction

spread over 16 areas in about 12 consecutive months, To ensure environmental hygiene,

living conditions and in accordance with the reality at the construction site, the construction

unit is required to make plans to rent houses of local residents for workers; In case of

construction of latrines, it must meet the requirements of QCVN 01: 2011 / BYT on hygienic

latrine standards; Therefore, the amount of domestic wastewater can be controlled by

mitigation measures. The impact is assessed at an average level.

➢ Impact on water environment due to overflow of rainwater

132

Stormwater runoff can be contaminated when flowing through areas containing pollutants

such as raw material dumps, outdoor construction areas ... the pollution nature of rainwater in

this case is Mechanical pollution (soil, sand, rubbish), organic pollution, grease. Stormwater

runoff at this stage has high turbidity due to swept soil mud from ground leveling, earthworks,

construction of main dams, spillways, managers and management roads. The concentration of

pollutants in stormwater runoff is estimated as follows:

Table 5. 20: Concentration of pollutants in stormwater runoff

TT Emission Concentration. mg/l

1 Nitro 0.5 - 1.5

2 Phospho 0.004 - 0.03

3 COD 10 - 20

4 Total suspended solid 10 - 20

Without treatment measures will flow into the lake and the downstream stream system

increases the sediment content in the receiving water, reducing the dissolved oxygen.

However, the construction time is expected to be constructed in the dry season, construction

contractors also have measures to manage and collect wastes regularly so this impact is

assessed as low.

➢ Impact on water environment due to construction waste water

Construction waste water is mainly generated by the activities of mixing concrete, mixing

mortar, washing tools and areas mixing cement mortar, stone sieving, and construction

materials. Characteristics of this type of wastewater has high SS content, high pH but low

flow so the scope of impact on the surrounding environment is low. Water for cleaning

equipment contains high content of grease and suspended solids. However, construction in the

form of rolling, so the number of machines used for construction is not large and scattered in

many locations. So the amount of water used for car washing is infrequent and negligible. The

volume of construction wastewater and equipment washing water at each project is estimated

at 3-5m3 / day.

Wastewater of the construction process, maintenance of concrete and water at the repair,

washing of motorbikes, equipment containing hazardous wastes such as cement, oil and

grease will be very toxic to the aquatic environment. However, the volume of these two types

of wastewater is not much so the scope of impact is assessed as low.

iii) Ecological impact

➢ Aquatic ecosystem

Construction activities overflow, drains will have a part of concrete submerged in water so

that water will wash away some impurities in the concrete that contaminate the lake water. If

the water level is low, the concentration of impurities that wash away from concrete may

increase to aquatic animals. Land encroachment causes loss of habitat, loss of spawning eggs,

death of juveniles, reduction of photosynthesis ability of algae ... This will break and alter the

adverse habitat of fish and other aquatic species, affecting aquatic ecosystem life. However,

due to poor biodiversity, in addition to applying mitigation measures and fast ecosystem

recovery, the impact assessment level is low.

➢ Terrestrial ecosystem

The process of leveling the ground will cause loss of habitat, residence, reproduction and

death of some species of land animals such as insects, animals living in caves such as snakes,

133

frogs, ... Dust, emissions from construction activities all affect the living and development

activities of flora and fauna in the region and surrounding areas such as: Dust on the leaves

reduces the photosynthesis process of green plants , heating leaves; SO2, CO, H2S gases

cause diseases for leaves and affect the development of green plants. However, this impact

does not affect much on the development of surrounding vegetation. The removal of trees,

vegetation and surface soil tillage often causes soil erosion.

The impacts are of short-term nature and are limited to the construction area, plus the

indigenous ecosystem that is capable of rapid regeneration after construction, so the impact

level is assessed as low.

iv) Impact on soil environment

➢ Impact on soil environment due to domestic waste

During the construction process, the total number of construction workers at each site of 16

lakes/dams is about 15 workers (mainly technical staff and skilled workers, simple items of

hiring local workers) work regularly at the construction site. The average volume of domestic

solid waste per person in Vietnam ranges from 0.35 to 0.8 kg/person/day (according to solid

waste management documents - Construction Publishing House), with consumption demand

and At the local development level, the volume of daily-life solid waste is about 0.5 kg /

person / day on average. Estimated daily volume of domestic solid waste generated on each

site is 15 x 0.5 kg/ person/day = 7.5 kg/day.

The domestic waste of workers on the construction site is a kind of waste that is easy to

decompose, contains many organic substances and pathogenic microorganisms if it is not

collected and treated before being discharged into the soil environment, it will make soil

contamination. However, the domestic waste of workers only arises in small and controllable

camps, so the level and scope of impact is assessed as low.

➢ Impact on soil environment due to excavation and filling activities in soil and waste

dumps

Activities of excavation, filling, dumping, exploitation of embankment materials at soil and

waste soil mines will disturb the surface covering soil layer, affecting the physical properties

of soil such as mechanical composition and porosity of land. Some soil and waste land mines

are only temporarily recovered so the removal of surface cultivated soil if not returned

according to regulations will affect the production and the field of plants when the project is

finished and handed over to people for use. The process of dumping can occur slipping,

erosion and soil pollution in the surrounding area.

➢ Impact on soil environment due to hazardous waste

Arising in camps, repair points for vertical construction machinery on the road including

types of wiping cloths, paper containing grease arising in the process of cleaning, repairing

equipment, machines and other plastic and iron boxes containing gasoline, oil, lubricants,

grease. The volume of hazardous solid waste from construction works is not large, it is

estimated that in a month, the camps and repair points arises about 3-5 kg / day / site. This

waste is collected and transferred to specialized processing units so the impact is assessed as

low.

➢ Impact on soil environment due to waste oil and grease

Waste oil and grease according to the regulations on hazardous waste management are

134

classified as hazardous waste, the source from the process of maintenance and repair of means

of transportation and construction. The amount of oil and grease generated during

construction depends on the following factors:

- Number of means of transportation and construction on site

- The amount of oil and grease discharged from transportation and construction vehicles

- Oil change cycle and maintenance of machinery and equipment

- Cheap oil and grease cleaning from maintenance and maintenance of construction

equipment

According to calculations for construction projects, the average amount of oil and grease

generated from transport and construction vehicles is 7 liters / time instead. The biggest oil

change and maintenance cycle is every 3 months. During the peak construction period, the

number of vehicles and construction machinery required to replace grease and oil used mainly

in the project is 16 vehicles per project. Therefore, the amount of grease and oil generated on

the average site is: (16 vehicles x 7 liters / time) / 3 months = 37.3 liters of oil / month.

Regarding hazardous waste collection and treatment at construction sites, the environmental

safeguard policy of the subproject is strictly regulated, specifically ECOP and regulations on

environmental protection in bidding; Hazardous waste generated is collected and treated by

units with appropriate functions, so the impact level is low.

c) Site-Specific impacts

The construction of different subproject items may affect some sensitive areas located near

construction sites. However, the impact level is assessed from low to moderate, takes place in

a short time and can be minimized.

5.3.3. Impacts during operation phase

During the operation phase of the reservoirs, some of the main negative impacts below are

identified and evaluated:

a) Risk of drowning:

The reservoir can be a bathing place for the local people. Therefore, the risk of drowning is

always potential if there are no appropriate preventive measures.

b) Repair and maintenance activities

These activities can lead to water shortages for a short time. This will have a direct impact on

agricultural production and living activities of the downstream people. And it will indirectly

cause impacts such as reduced income due to time of cultivation, environmental pollution and

disease due to lack of water. However, this impact is assessed as small because the repair and

maintenance time does not last long (about a few weeks).

c) Emergency flood discharge and dam failure

Due to the characteristics of the subproject to improve dam safety, the likelihood of dam

failure is very low. Emergency flood discharge may affect downstream communities without

prior notice, causing a direct impact of downstream flooding, property, crop and life losses

and leading to indirect impacts such as environmental pollution and disease outbreaks and

loss of income.

d) Causing environmental pollution due to production development

According to statistics in Table 5.23, the area irrigated in the subproject area increased to 109

ha of winter-spring crop and 120 ha of summer-autumn crop due to the ensured reservoir

capacity after upgrading and repairing, leading to increased use of fertilizerand pesticides.

The improper use and handling of agricultural waste can harm the environment and the health

of farmers. However, in sub-project communes, controlled use of pesticides provided by non-

agricultural producers to the market is self-sufficient, so this impact is assessed at low.

5.4 Analysis of impact types

5.4.1 Cumulative impacts

The subproject consists of many dams, however, the dams are scattered and independent in

the province. Moreover, the size and nature of the subproject activities are small and simple,

so that the implementation of the subproject activities is not likely to cause cumulative effects.

According to the surveys and exchanges with the concerned agencies, at present, in the

construction area of the WB8 Subproject in Yen Bai province, there are not other major

projects being implemented on the same spatial scale and time, so the cumulative effects

created by other projects are considered to be non-existent.

5.4.2 Direct impacts

The subproject implementation will have 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 have direct impacts on the quality of the surrounding

environment such as the air, the soil and the water due to the generation of waste like

139

emissions and wastewater and the removal of vegetation.

5.4.3 Indirect impacts

The temporary or permanent loss of land will affect the livelihoods of affected people like

reducing or losing income, occupation change and possible social contradictions. Indirect

impacts are also identified through the risk of deterioration of water quality due to soil erosion

caused by vegetation clearing from the construction. Water pollution due to waste generated

from the construction may lead to a decline in the composition and decline in number of

individuals of aquatic species. Soil compaction due to the use of heavy equipment on

farmland possibly leads to a decline in the number of useful soil microorganisms 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 of the risk of erosion and flooding.

5.4.4 Temporary impacts

In general, most impacts associated with construction activities within the subproject area

such as noise, vibration, dust and emissions, and the generation of solid waste and wastewater

are short. They will no longer exist when construction activities are completed.

5.4.5 Long term impacts

The permanent loss of productive land will be a lasting impact on the affected people as some

households are perceived as losing productive material and leading to a change in their

occupation. Also, environmental incidents such as oil spills or hazardous chemicals will

create long-term effects on the environment and human health as these chemicals get long

decomposition, which penetrate into the soil, the water and the food chains. In addition, the

risks of occupational accidents will be addressed with long-term effects when workers' health

is diminished or lost.

140

CHAPTER VI. ANALYSIS OF ALTERNATIVES

6.1. Without subproject

The reservoirs of the subproject were built from the 80-90 decade of the 20th century, have

been operating for about 30-40 years and have contributed to stabilizing production, ensuring

safety for people and infrastructure in the project area. However, due to the long construction

period, most of the dams are self-built and are earth dams, failing to meet dam safety

standards. The key works have been degraded and damaged, affecting the safety of reservoirs

and water supply capacity for downstream areas. In case of not implementing the project, the

risk of dam failure may occur, which will affect 769 ha of cultivated land, over 6,000

households, National Road 37, National Highway 32, provincial road 170 and District and

commune roads go through communes in the project area and many other infrastructures.

Thus, the investment in repairing, upgrading and modernizing immediate benefits is to

overcome the deterioration and deterioration of construction items. In the long term, to

increase the dam safety level, to ensure stable production and people's life, reduce the risk of

damage to the downstream areas, promote their tasks and improve the exploitation efficiency

of works, sustainable development of water resources of the catchment basins in the

subproject.

6.2. With subproject

The implementation of the subproject will improve dam safety, limit the risks of dam failure,

and stabilize production and people's life in the region. However, during the project

preparation phase and the construction of key work items, there will be negative impacts on

the environment. Impacts can be limited or reversed if the investor chooses the appropriate

options and implements mitigation measures. A number of measures have been selected to

minimize the following environmental impacts:

6.2.1. Alternatives when executing items under normal water level

The construction of dams and dams under the NWL, new and repaired drains to drain water

must lower the water level for construction to affect production and water supply for

downstream areas. Instead of having to compensate for production losses due to construction

water cuts, the first owner chose the following option to not affect production and save

compensation costs:

a) Measures to arrange appropriate construction time so as not to affect downstream

production

According to the survey results, the localities in the project area do not produce winter crops

because there is no water. The investor has arranged the construction time for the dam

sections below the NWL, repaired or renewed the intake sewer in the period from September

15 to December, this period harvested winter rice and planted winter crops, so does not affect

production in the downstream area and does not have to compensate for damage caused by

cutting water.

b) Plan for embankment of dykes when constructing new sluices for water intake so as not to

affect downstream production

For 5 new works, the intake of water (Original Lake, Lang Ai, Phu Nham, Nghia Lo Farm,

Village 26), in case of prolonged construction period, may affect the production of winter-

spring crop of the lower region. The investor has chosen the embankment plan to construct a

new sluice gate, while using this old sluice gate to supply water in the downstream area.

141

When finishing the new sluice gate, putting it into use will destroy the old culvert, which will

not affect production.

c) The plan to use other technical measures to supply to the downstream area during the time

of lowering the lake water level for construction

During the construction of the dyke to construct the upstream roof, to ensure the irrigation

water in production will use pumps to serve irrigation pumps. The investor and the

construction unit need to develop a support plan (compensation, flow, irrigation area, water

use area ...) and discuss with the lake management unit of the company. : Nghia Van

Company Limited (managing the villages of Thon 26, Phu Nham, Nong Truong Nghia Lo

lake); Dai Loi Company Limited (manages Khe Dua, Khe Hop, Khe Ngang, Khe Vai, Khe

Chinh and Van Yen districts; Lang Ai, Roong Den and Tang An lakes Luc Yen district); Tan

Phu Co., Ltd. (managing Hang Luon, Goc Nhoi, Khe Hoai lakes in Yen Binh district; Tu Do

lake and Chop Du district in Tran Yen district) shall coordinate with each other when

required.

For Lang Ai Lake: The investor and the construction unit need to build a specific support plan

with Dai Loi Company Limited and Luc Yen Clean Water and Environment Joint Stock

Company to install additional water supply pipes (about 100m of HDPE D500 pipe) from the

dyke to the water intake tank (BxHxL: 3 x 3 x 3 m) to ensure stable water supply for all

people in Yen The town and a part of Lieu Do commune.

The investor must have a notice to the local authorities and water users about the water cut

schedule, the time to cut water for construction so that the people have plans to store water

into canals and aquaculture ponds.

6.2.2. Alternative measures when selecting the location of ancillary works (land mines,

disposal sites)

a) Selecting material site location:

The construction and repair of earth dams must use backfill materials from material mines.

The exploitation of embankment land will affect the production area, compensation costs due

to land acquisition, impact on the environmental landscape and the investor must implement

the licensing procedures for exploitation in accordance with the law. Vietnam law. In order to

limit the above impacts, the Investor has chosen the alternative plan as follows: For all lake

projects under the subproject, the Investor chooses the option of exploiting soil from hills and

yards high in the work protection corridor located in the reservoir area or taking land from

hilly areas, high yards of households near the lake (there is an agreement to agree on the land

of households). This option has the advantage of saving transportation costs (distance from

the mining site to the earth dam from 0.5 km to 3.0 km), saving the cost of buying and

transporting from material mines. This option may increase the risk of erosion and

sedimentation of the lake bed. However, construction time is mainly in the dry season, so

these impacts will be limited.

b) Selecting locations of disposal sites:

The improvement and upgrading of earth dams, intake culverts and flood spillways will

generate an amount of organic soil that is not reusable to build the above items. Therefore, it

is necessary to transport to suitable locations for disposal. This will affect the area of

productive land and crops of people in the disposal area, affecting the environmental

landscape, increasing the cost of compensation for land and crops. To minimize the above

impacts, the Investor has chosen the following alternatives:

142

- For the projects of Khe Vai, Goc Nhoi, Khe Hop, Hang Luon, Khe Chinh, Chop Tuy, Phu

Nham and Khe Ngang, the investor has cooperated with the locality to select the disposal area

as vacant areas. , weeds, sunken areas along the foot of the mountain, along the way, suitable

for containing waste, separated from water bodies, from the foot of the building from 0.3 to

1.5 km, isolated from residential areas from 0, 5-1.5 km and no compensation for land and

crops.

- For the works of Tu Do, Roong Den, Lang A, Nghia Lo and Thon Lo Farms, 26 investors

have cooperated with the local authorities to dump waste soil to raise the level of local public

works such as : Market, resettlement area, village cultural house. These locations are 1.5-3.2

km away from the construction site and do not have to compensate for land and crops.

- For Don An, Khe Dua and Khe Hoai reservoirs, waste is discharged at the vacant land at the

foot of the dam downstream of the project, with a distance from 0.2 to 0.3 km to the foot of

the project. These locations are vacant and abandoned land, managed by the CPC, not

transported, not compensated for land and crops.

- There is 1 part of waste soil of Tu Do Lake dumped in the soil currently growing corn of 1

household with an area of 2000 m2. This position agreed with the consent of the households

and only supported the land on the land. No compensation for land.

6.2.3. Alternative measures when selecting materials and waste soil transportation routes

Transporting materials and waste soil will affect people on both sides of transport routes,

increase traffic and potentially damage these roads. To minimize the impacts mentioned

above, the consultant has organized surveys and selected the shortest transport routes and less

traveled through the most residential areas to save money and limit the impact. to people in

the area, specifically as follows:

- For Phu Nham lake works, Thon 26, Khe Hoai, Hang Luon and Goc Nhoi caves, to make

the best use of transporting materials on the roads of National Highway 37, National Highway

32 and provincial road 170 to limit transportation through residential areas.

- For the remaining projects, it is required to transport materials through district roads, inter-

villages and inter-communes, the investor has a plan of use with a tonnage of not more than 7

tons to limit damage to roads and do not transport at peak hours to limit the impact on

people's travel.

CHAPTER VII. ENVIRONMENTAL AND SOCIAL MANAGEMENT PLAN

7.1 Objectives

Ensure the compliance with the World Bank’s regulations as well as Vietnam’s legal system,

standards and guidelines applied at the provincial and national levels.

Ensure that sufficient resources are allocated based on the subproject budget to carry out the

activities related to the ESMP.

- Ensure that the environmental and social risks of the Subproject are adequately predicted

and managed.

- Ensure specific and feasible response plan with unforeseen environmental issues in the

subproject's environmental impact assessment.

- Create an effective feedback mechanism for further improving environmental protection

results.

- The Environmental and Social Management Plan (ESMP) outlines mitigation, monitoring

and institutional measures that will be implemented during the development and operation of

the Subproject to avoid or control adverse impacts on the environment, society and outlines

the actions required to implement mitigation measures. The ESMP creates a useful link

between adverse impact and mitigation measures and ensures that such measures are

implemented.

- The ESMP imposes responsibilities for the implementation, monitoring, time and cost for

the proposed mitigation measures. The summary of the Subproject’s environmental and social

management plans is presented in the following sections.

7.2 Mitigation measures

7.2.1 Mitigation measures during the preparation phase

a) Implementation of compensation and assistance for affected households

- The Subproject Owner contracts and coordinates with the District Centers for Land-fund

Development, the Department of Natural Resources and Environment, the District People's

Committees, the Divisions of Natural Resources and Environment, the Commune People's

Committee, the concerned organizations, households and individuals whose land and assets

attached to land are located in the acquired area to inform and guide the accuracy, public

measurement, determination of ownership, asset declaration in order that the compensation,

support and resettlement plans are approved the most exactly.

- Disseminate the compensation, support and resettlement plan of the subproject.

- Disseminate the proper implementation of the State's legal obligations and interests.

- Publicize detailed compensation prices of each type of damage to affected households.

- Payment of compensation to the right subjects and on schedule.

- Coordinate with local authorities if any disputes occur to ensure the smooth site clearance.

The cost of compensation, support and other management costs for affected land/property

(land, houses, structures and trees) for the Subproject are shown in the table below (For more

details, please refer to the RAP report).

b) Mitigation measures for explosives, filling geological exploration bores

The subproject will hiring a company that has suitable functions and capabilities such as the

Center for Landmine and UXO Exploitation under Military Region II to clear mines and

explosives before the construction of all sites of the project components; ensuring safe

distance and warnings for people during the implementation in accordance with QCVN 01:

2012/BQP - National technical regulations on clearance of explosive ordnance and QCVN 02:

2008/BCT-National technical standards on safety in transportation, preservation, use and

destruction of industrial explosive materials.

After drilling for geological exploration, the design surveyors will fill drilled holes and repair

the ground in the areas to minimize washing dirt via drilled holes which may affect the

underground water quality.

c) Measures to minimize the impact of site clearance activities.

- For trees, crops, fruit trees, short-term industrial plants ... informing people to take initiative

in recalling products before conducting site clearance. Support people in moving timber trees

and fruit trees to unaffected areas to continue farming.

- For properties and works to be demolished or relocated, it is necessary to notify in advance

so that people have plans to move animals, valuable assets or actively dismantle to move to

unaffected locations. .

- Land and waste land areas only temporarily recover land, after the project is completed, they

will continue to return ground to production people. Excavation of soil causing disturbance to

soil layers will affect cultivation ability, so before exploiting materials or discharging waste

materials, it is necessary to peel off the soil layer, also known as the soil layer (25-30cm

thick) separately. After completing the project, it will rearrange the arable land layer to limit

the time to improve and restore the soil environment.

7.2.2 Mitigation measures during construction

7.2.2.1 Mitigation measures to construction impacts

Mitigation measures are developed based on the World Bank Group's environment, health and

safety guidelines and national regulations and standards to minimize construction impacts, in

general, which are presented in the ECOP. The ECOP describe the typical requirements

implemented by the Project Owner and supervised by the Construction Supervision

Consultant during the construction process. The ECOP will be incorporated in the appendices

of bidding documents and contract documents. The mitigation measures are identified for the

following issues:

- Dust and emissions;

- Vibration and noise;

- Waste management;

- Management of hazardous materials and chemicals;

- Management of camps;

- Biological effect;

- Soil erosion;

- Sedimentation and drainage;

149

- Stockpile and borrow pits management;

- Traffic safety management;

- Interruption to exsiting infrastructure services;

- Chance finds;

- Management of labor influx ;

- Occupational health and safety;

- Community Health and safety;

- Communication with the local community.

1) Dust and emissions - The Contractors are responsible for the compliance with the

requirements of Vietnamese regulations on ambient air quality.

- The Contractors must ensure that dust emissions are minimized

and will not disturb local people, while implementing dust control

measures to maintain a healthy working environment and minimize

disturbance to surrounding households.

- The Contractors are responsible for the implementation of dust

mitigation measures (e.g. use of water sprinklers, covering vehicles

for transporting materials ...).

- Construction materials such as cement, sand and gravel must be

properly covered and secured during transportation to prevent

spillage of soil, sand, other materials or dust.

- Report on the implementation of the CESMP to the PPMU and preparation of

environmental and social monitoring reports during construction phase.

7.4.4 Compliance with contract and legal requirements

The construction activities not only comply with the environmental protection and pollution

control requirements of the contracts but also comply with the Law on Environmental

Protection and Pollution Control of the Vietnamese Government.

All Contractors’ reports on construction methods submitted to the CSC and the PPMU for

approval must provide with adequate measures to control pollution and protect the

environment.

The CSC and the PPMU will also review the progress and program of the works to verify that

the relevant environmental laws are violated and to possibly prevent any one who manage to

break the law.

The Contractors must copy the documents related to the SSEO and the ES of the CSC and the

PPMU. The documents must at least include updated work progress reports, updated

construction methods, and other licensing applications under the Environmental Protection

Law and all valid permits/licenses. The Environmental and social staff of the CSC and the

PPMU will also have right to access to the website logbook upon request.

After reviewing the documents, the environmental and social staff of the CSC and the PPMU

will advise the PPMU and the Contractor on any non-compliance with the contractual and

legal requirements relating to the environmental protection and pollution control so that they

can continue the next actions. If the environmental and social staff of the CSC and the PPMU

conclude that the status of the permit application and any environmental protection and

pollution control activities may not be consistent with the works or may lead to violations of

environmental protection and pollution control requirements, they will promptly notify the

Contractor and the PPMU.

7.4.5 Reporting

In addition to the progress reports, the Contractor shall also provide reports on the

Environmental, Social, Health and Safety (ESHS) data set out in Appendix B to the Standard

192

Bidding Document (SPD). In addition to the reports in Appendix B, the Contractor shall

immediately notify the PPMU of any incidents in the following groups. Full details of these

incidents will be provided to the PPMU within the time agreed upon with the PPMU.

- Confirmation or any act which is likely to violate law or any international agreement;

- Any death or serious injury (time damage);

- Significant adverse effects or damage to personal property (e.g. car accidents, damage

caused by flying stones, working outside the boundaries)

- Severe pollution of groundwater or damage to or destruction of habitats or endangering

rare species (including protected areas); or

- Any allegations of sexual harassment or sex offenses, child abuse, defamation, or other

violations related to the child.

7.5 Grievance redress mechanism

All complaints related to any subproject issues will be resolved through negotiations to reach

consensus. The complaints will go through three stages before appealing to the courts. The

agencies in charge of complaint settlement will pay all administrative and legal fees related to

the acceptance of complaints. This cost is included in the Subproject budget.

7.5.1 Procedures for complaints and settlement

(i) The People's Committees at commune levels (CPCs): The affected people can bring their

complaints to any members of the CPCs through the village heads or directly to the CPCs in

writing or orally. The members of the CPCs or the village heads will inform the CPCs of the

complaints. The CPCs will work directly with the affected people who complains and decide

on the reconciliation/settlement within 5 days of receiving the complaints (about 15 days for

the mountains and remote areas). The secretaries of the CPCs are responsible for filing and

archiving documentation of all complaints that the CPCs handle.

After decisions are made by the CPCs, the concerned households can make complaints

against within 30 days. In the case of the second decisions made by the CPCs, if the

193

households are still unsatisfied with the decisions, they can appeal to the superior people's

committees in accordance with the complaint procedure stipulated in the Law on Complaint in

2011 and related documents.

(ii) The District People's Committees (DPCs): When there are complaints, the DPCs will have

a period of 15 days (or 30 days for mountains and remote areas) to resolve them. The

DPCsare responsible for filing and archiving documentation of all complaints that they

handle.

When the DPCs issued decisions, the complainants can appeal again within 30 days. In the

case of the second decisions made by the DPCs, if the households are still unsatisfied with the

decisions, they can appeal to the provincial people's committee in accordance with the

complaint procedure stipulated in the Law on Complaint in 2011 and related documents.

(iii) The Provincial People's Committee (PPC): The PPC has a period of 30 days (or 45 days

for mountains and remote areas) from the date of receipt of the complaints to settle. The PPC

is responsible for filing and archiving documentation of all complaints that it handles.

After the PPC issued decisions, the complainants can appeal again within 45 days. In the case

of the second decisions made by the PPC, if the households are still unsatisfied with the

decisions, they can appeal to the court within 45 days. The PPC will have to pay

compensation costs to an account.

(iv) The Provincial Court. When the complainants take their cases to the provincial court and

the rules of the court are favourable to the complainants, the provincial authorities will

increase the compensation to a level that the court can approve. In the case that the court

judgments are favourable to the PPC, the complainants will be reimbursed the charges they

paid to the court.

The complaint decisions must be sent to the complainants and the involved parties and

publicly posted up at the offices of the people's committees of the competent levels. The

complainants will receive the judgments three days at the commune level and seven days at

the district or provincial levels after there are decisions on the settlement of their complaints.

To minimize the number of complaints at the provincial level, the PPMU will coordinate with

Song Lo, Lap Thach, Tam Dao and Phuc Yen District Compensation Committees to organize

the consultations on the complaint settlement. Its role and capacity is to provide

compensation, assistance and resettlement to affected households and displaced persons.

Personnel: The environmental and resettlement staff selected by the PPMU will design and

maintain a database on the subproject complaints from affected households, including

information like the nature of the complaints, the sources and dates of receipt of the

complaints, the names and addresses of the complainants, the action plans, and the current

status.

For verbal complaints, the agency that settle complaints will record these requests in a

complaint form at the first meeting with the affected households.

7.5.2 Contractors and Construction Supervision Consultant

Beside, during the construction process, the grievance redress mechanism will be managed by

the Contractors under the supervision of the CSC. The Contractors will inform affected

communities the availability of the grievance redress mechanism to resolve grievances and

concerns regarding to the Subproject. This will be done through a community consultation

and disclosure process whereby the Contractors will regularly communicate with affected

communities and relevant agencies. The meetings will be held quarterly, monthly at least. The

subproject information flyers will be announced. The announcements will be made on the

194

local media and announcements that the upcoming activities will be posted.

All complaints and actions taken by the Contractors will be recorded in the subproject

monitoring reports. Complaints and claims for damages may be made in the following forms:

- By word of mouth: directly to the CSC and/or the Contractor's security guards or regional

office representatives.

- In writing: by hand or by posts to specific addresses.

- By telephone, fax, e-mail: to CSC, security guards or Contractor's representative.

When a complaint is received, the CSC and Contractor's safeguard officers or representatives

will file the complaint and record incidents subsequent to the complaint until it is settled.

Immediately after receiving complaint, it is necessary to make 04 copies. The original will be

kept in the file, 01 copy will be kept by the Contractor's safeguard officer, 01 copy will be

sent to the CSC and 01 copy will be sent to the PPMU within 24 hours of receipt of the

complaint.

The complain information recorded will include:

- Dates and hours of complaints.

- Names, addresses and contact details of complainants.

- Brief descriptions of complaints.

- The actions taken to resolve complaints, including contact persons and findings at each

stage of complaint settlement process.

- Dates and hours when complainants are contacted during the resolution process.

- Final decisions about complaints.

- Dates, times and how complainants were informed.

- Signatures of complainants when making decisions.

Small-scale claims will be resolved within a week. Within two weeks (and every week

thereafter), the written response will be sent to the complainants (manual, post, fax, e-mail)

which states the procedures to be followed and the process by date.

The main objective is to solve the problem as quickly as possible by the simplest means,

involving as few persons as possible and at the lowest possible level. Only if the problem can

not be solved at the simplest level and/or within 15 days, other functional agencies will

participate. Such situations may arise, for example, where damages are claimed, the volume

of claims can not be resolved, or the causes of damages are determined.

7.5.3 The World Bank’s Grievance Redress Mechanism

The World Bank Grievance Redress Mechanism: Individuals and communities can believe

that if a subproject funded by the World Bank adversely affects their lives, they may file

complaints to that subproject grievance mechanism or the World Bank's grievance redress

committee. The World Bank's grievance redress committee ensures that complaints are

addressed in a timely manner related to the subproject. Individuals or organizations affected

by the subproject may file complaints with the World Bank Inspectorate to determine if any

damage occurs or may occur, as a result of failing to complying with the World Bank policies

and procedures. Complaints may be made at any time. When the matter is of concern to the

World Bank, the PPMU will have responsibility to answer. For more information on how to

file a complaint with the WB’s grievance redress committee, please visit

www.worldbank.org/grs. For more information on how to file a complaint with the World

195

Bank Inspectorate, please visit www.inspectionpanel.org.

7.6 ESMP implementation plan

7.6.1 Contractor's Social and Environmental Management Plan

As soon as the contracts are signed, based on the ESIA report, the subproject construction

methodology, the construction plans which are approved by the CSC and the PPMU, the

Contractors prepare the ESMP of their packages and submit to the PPMU for review and

approval.

Once the ESMPs are approved, the Contractors will implement measures to minimize

environmental and social impacts on site.

The ESMP information will be posted at the workers’ camps and workplaces to disseminate

information about mitigation measures for workers.

The Contractors post information of mitigation measures at the entrances of the sites,

including the addresses, representatives, phone numbers of the parties involved for the local

community to follow and contact as necessary.

Assign staff responsible for environment safety; train knowledge on environment safety and

workers’ health.

Survey, check the environmental status at site, report to CSC/PPMU if there are significant

differences compared to the environment.

Sign contracts with authorized units for treatment of daily-life wastes, hazardous wastes, and

supply of clean water.

Manage workers and construction equipment and issue new certificates in case of expiration.

Implement the ESMP and update, submit to the CSC/PPMU for approval if changes are made

prior to application.

Collaborate with the CSC/PPMU to resolve complaints from people about environmental

issues and the safety of the packages in a timely manner.

Report on the implementation of the monthly ESMP.

7.6.2 Start up the sub-project and personnel

The Contractor's Environmental Safety Officers must be trained in the relevant regulations,

have certificates of occupational health and safety, and are full-time employees on site.

The provision of training on occupational health and safety for workers and the regular

inspection of the health and safety service on site must be implemented.

7.7 Capacity building and training

7.7.1 Training on safeguard policy

Since the PPMU have implemented projects funded by the World Bank, some PPMU staff

may have a clear understanding of the World Bank’s safeguard policy requirements. The

PPMU has appointed an officer to be responsible for the environmental safeguard of the

Subproject. This environmental officer has participated in some safeguard training courses

organized by the World Bank and the CPMU at the early stage of the subproject

implementation. Training and capacity development, however, is required annually through

technical assistance of the World Bank’s Safeguard Policy Officers addressing new safeguard

policy requirements. Because the new environmental, social, health and safety (ESHS)

requirements are set out in the standard bidding documents, the trainingon the ESHS

http://www.inspectionpanel.org/

196

requirements will be provided by the World Bank’s Safeguard Policy Officers to the

environmental and social staff of the PPMU, the CSC and the environmental and social staff

of the Contractors as soon as they are mobilized. The PPMU will be responsible for

organizing the training in coordination with the World Bank’s Safeguard Policy Officers.

Such training should be organized at an early stage of implementation to ensure that the

ESMP is properly and appropriately translated into the bidding (and subsequent contract)

documentation. The technical assistance should be undertaken by appropriately skilled and

experienced personnel of CSC, and be undertaken in accordance with a Terms of Reference

that includes specific reference to developing effective Employers Requirements sections of

the SPDs.

7.7.2 Training on occupational health and safety

The provisions will be made to provide occupational safety and health training for all new

employees to ensure that they are informed of the site's basic workplace conditions and work

practices to protect personal and prevent injuries to their colleagues.

The training will include perceptions on basic hazards, specific hazards, safe work practices,

and emergency procedures for fire, evacuation, and natural disasters, which must be practice

properly. Any specific hazards or color codes to be used will be considered thoroughly as part

of the training orientation.

7.7.3 Orientation of visitors

If visitors are allowed accessing to the areas with hazardous conditions or substance presence,

visitor orientation and control program will be established to ensure that they do not enter

dangerous areas without the accompanying persons.

7.7.4 Training contractors and new workers

The PPMU will ensure that workers and contractors, before undertaking new jobs, receive

adequate training and information so that they can understand the hazards at work and protect

themselves from the hazards which may occur. The training will include:

- Understanding about materials. equipment and tools

- Understanding about the hazards of operation and how to control them

- Potential risks to health

- Alerts to prevent exposure

- Sanitary requirements

- Wearing and using protective clothing and equipment

- Actions to severe operating conditions, incidents and accidents

7.7.5 Training on basic occupational health and safety

A basic training program and intensive courses will be deployed as needed to ensure that

workers are oriented towards the specific hazards of individual work tasks. The training will

generally be provided to managers, supervisors, workers, and occasional visitors to risk and

hazardous areas.

Workers with first aid and rescue obligations receive special training not to exacerbate the

exposure and health hazards to themselves and their colleagues. Training will include the risk

of transmitting diseases through blood due to contact with body tissues and body fluids.

Through appropriate contractual terms and monitoring, the PPMU will ensure that service

197

providers as well as contractual workers and subcontractual workers are adequately trained

before commencement of their works.

The PPMU will be responsible for coordinating with the construction supervision consultants

and the contractor's social environment officers to organize the training courses mentioned

above.

7.8 Environmental monitoring plan

7.8.1 Monitoring the compliance with 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 and communities in 11 reservoir areas will perform monitoring tasks in

accordance with the Government’s regulations, the Law on Environmental Protection 2014

and Decree No.80/2005/ND-CP regarding the regulations on investment community

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.

198

7.8.2 Monitoring environment quality

(a) Periodic monitoring

An environmental monitoring program for the air quality, soil and water supply information

can be used to assess the effectiveness of pollution management strategies. A systematic

planning process is recommended to ensure that the collected data is appropriate to their

intended purpose (and to avoid unnecessary data collection). This process, sometimes referred

to as the process of data quality objectives, determines the purpose of data collection,

decisions based on data and consequences of making wrong decisions, time and place

boundaries, quality and data required to make a correct decision. The environmental

monitoring program will consider the following factors:

• Monitoring parameters: The selected monitoring parameters should reflect disturbing

pollutants related to the subproject processes.

• Basic calculations: Prior to the construction of the Subproject, monitoring the

environment quality in the ambient and in the subproject area should be carried out to assess

the contamination level of the main pollutants to distinguish between the conditions of the

current surrounding environment and impacts related to the Subproject.

• Type and frequency of monitoring: The ambient environmental quality data generated

through monitoring program should represent contaminated pollutants caused by the

Subproject by time. The time and monitoring frequency can also be arranged from continuous

to infrequent, monthly, quarterly or yearly occurrence.

• Monitoring locations: Monitoring the ambient environmental quality may be external or

within the subproject area by the Subproject Owner, DONRE, or by the cooperation among

the parties. The locations of the monitoring stations should be established based on the results

of scientific methods and mathematical models to estimate potential impacts on the receptors

from emission sources, taking into account such aspects as the locations of the communities

which are likely affected.

• Sampling and analysis methods: The monitoring programs should use national or

international methods for sample collection and analysis, such as those published by the

International Organization for Standardization (ISO). The sampling must be conducted by or

under the supervision of the trained staff. The analysis will be by authorized or certified

entities for this purpose. The quality control plans (QA/QC) should be documented to ensure

that the quality of data is consistent with the intended use of the data (for example, the method

limits detection to less than the level of interest). The monitoring reports should include

QA/QC documents.

The noise monitoring programs can be useful for the purpose of setting the ambient noise

level, which is present in the proposed subproject area or useful for checking the noise level at

the operation phase. The noise monitoring programs should be designed and implemented by

trained professionals. Typical monitoring cycles should be sufficient for statistical analysis

and may last up 48 hours in parallel with the noise monitoring devices to to able to record

continuous data during this time period, or by hour, or more often, if appropriate (or include

different time periods for several days, including weekdays and weekends). Sound indicator

types are recorded depending on the types of noise which is being tracked and are determined

by the noise specialists. The equipment should be placed about 1.5m from the ground and not

closer than 3m to any reflective surfaces (e.g. walls). In general, the noise level is limited by

the level of ambient noise or the level of baseline noise in the absence of the noise source

which is being investigated.

The details are shown in the table below.

The implementation time for each project under the subproject is expected to be 12 months, the location of

periodic sampling sampling coincides with the sampling position during the ESIA implementation. During

the deployment process, depending on the construction conditions, items can be adjusted to the

environmental quality monitoring position to suit reality. Location of monitoring for each project see

diagram in annex 4.

Funding for environmental monitoring: The total cost of environmental monitoring in the

construction and operation phase is estimated: VND 434,046,000 (Four hundred and thirty

four million and forty six thousand dong). This cost is implemented by the construction

contractor, as a basis for checking the quality of the surrounding environment during

construction (Table 7.9).

(b) Incident monitoring

The purpose of this monitoring is to assess the soil and water pollution levels caused by

sudden discharge like discharge of wastewater and oil into nearby water and soil sources and

to make timely pollution control decisions to reduce environmental risk.

An incident monitoring plan will be developed by the CSC in the initial stage of the

subproject implementation and submitted to the PPMU for approval. This plan identifies the

potential environmental risks associated with the discharge of waste, like waste oil and

wastewater, into nearby water bodies. The plan also identifies resources to monitor this issue,

such as personnel, equipment, location and monitoring parameters, analytical methods,

dedicated laboratories, 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. 72/2007/ND-CP on Dam Safety Management.

7.9. Estimated cost

The proposed budget for the implementation of the ESMP, including monitoring and capacity

building, is summarized in Table 7.10 below:

201

II Environmental monitoring 434,046,000

Total 884,046,000

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/QD-

TTg 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".
