4. KEY ENVIRONMENTAL AND SOCIAL ISSUES

4.1. Environmental issues

Table 4. 1. Environmental issues of project No

Impacts Impact description

PREPARATION AND CONSTRUCTION PHASE

1 Land acquisition � Total area of acquired land for project is 87.74 ha

� Permanent acquired land is 85.69 ha of which:

- 79.83 ha for reservoir

- 5.86 ha for main components such as headwork, intake,

powerhouse, discharged sewer etc

� Temporary acquired land:

22


- 2.05 ha for campsites, auxiliary facilities such as disposals,

material storages

� The whole of acquired land is located in Luu Kien and Xa

Luong commune, Tuong Duong district, Nghe An province.

Share of land use consists of cultivated forest land, housing

land, land of river and stream, bald land, agricultural land,

bush, bamboo etc.

(Refer Table 4.2 for more detail)

2 Landslide, erosion

and sedimentation

� Cause of landslide/erosion

- Activities of excavation/backfilling of rock/soil at the main

components of headwork such as spillway, intake,

powerhouse, switchyard during construction phase lead to

risk of landslide/erosion

- Construction of dam and storage water in reservoir will

impulse landslide especially at unstable ground. Moreover,

in case of long, heavy rain, water level rises; the new land is

submerged leading to partial landslide

- The process of discharging water through the spillway will

be capable of causing flood and partial landslide in the area,

� Project features

- The project region is a part of the South West wing of Ca

river structural belt, belongs to the Viet Nam - Lao uốn nếp

domain

- The position of the headwork is located at the South,

Southeast - North, Northeast V-shaped twist of Nam Mo

River. The entire area of dam is lower mountain terrain, no

forest, mainly bush, rare big trees.

- The river is 116m wide, which has almost disclosed stone ,

the continuous flow of water is close to the right bank with

32m width, deeper than reefs about 14m

- Right shoulder of the dam’s route is thin, but terrain is steep,

under the impact shock when blasting or excavation gravity

imbalance, there may arise new landslide blocks. So it

should pay attention during the construction. Left shoulder

terrain is not sloping, therefore it is unlikely to happen slide

slip.

- 30 residential houses in Ban Ang hamlet are contiguous to

the headwork to the southeast, the distance to the nearest

house is estimated to be 350m. 21 residential houses in Ban

Kien hamlet are contiguous to reservoir's protected areas

corridor to the northwest . Due to the location distance risks

to landslide to the local households are relatively close

compared to other hydropower projects therefore the

landslide processes can affect the life and property of local

23


people so it is necessary to monitor strictly the locations that

exposes to high potential of landslide so that could provide

appropriate mitigation measures.

� Impacts of landslide/erosion

- Sedimentation of Nam Muc river and reservoir

- Water quality reduction

- Changing of water flow in downstream

- Life and property of people affection

3 Impacts on surface

water quality

� The main reasons cause to water surface pollution in the

construction phase:

- Domestic waste water from 310 workers in project site (at

peak time).

- This type of waste water contains BOD5, residue, TSS

organic substance

- In average, each worker uses 31 water litters per day. If the

domestic waste is 80% to the provided water, the average

sewage of 310 workers will be 24,8m3 per day.

- To wash vehicles, machines, manufacturing equipment,

concrete maintenance, road cleaning, ... at peak time uses a

relatively large amount of water (about 62.58m3/day).

Because the wastewater from these activities (mainly from

aggregate washing station, vehicle- washing machine, road

washing and a portion of the concrete maintenance) are often

highly alkaline. If they directly discharge, it can increase the

alkalinity of Nam Mo river water and nearby streams

- Run-off water: rainfall runoff over the entire surface of the

work will entrain impurities, especially splattered grease and

dirt from the construction activities and work items,

especially the work of embankment cofferdam, excavation

construction spillway, energy route.

- Stormwater runoff often sweeps under a large amount of dirt,

concrete spillage, garbage, ...so it has high concentration of

solids and other impurities. As a consequence, it increases

turbidity in Nam Mo River downstream, causes sediment

deposition in streams in the region, affects the lives of

aquatic plants in streams and Nam Mo river downstream. If

spilled gasoline, solid waste and construction activities are

not properly managed, these type of waste will negatively

affect to surface water when workers directly discharge

waste to streams and reservoir...

- Organic waste from the decomposition of animal and plant

when storing water of the reservoir.

� Impacts of surface water pollution

24


- Increasing of turbidity, reducing of water quality of Nam

Muc river water.

- Affecting to life of aquatic species

� Project features :

- Investigation process in Ban Ang and Nam Mo river

downstream area shows that almost households do not use

Nam Mo River water for domestic water useage. Water

supply is led mostly from mountain streams to each

household. Therefore, the above effects do not greatly affect

the life and health of the people.

- The decline in Nam Mo river water quality affects to

farming, aquaculture operations of people in downstream

area, However, this effect is only temporary during the

construction period and can be minimized

4 Air pollution � Sources of pollution, the level and objects influenced from

excavation, leveling, construction activities

- Dust and exhaust gases emitted from the excavation,

leveling, transport of materials used in construction,

construction activities and operation of construction

machinery and equipment

- According to calculation, the level of dust generated by soil

and rock excavation exceeds the permission standards from

3.3 to 11.5 times

- However the size of dust generated in this process mostly is

big so the capable of spreading is low. Moreover, the

excavation operation often interrupt, mainly in the

construction area, which is far away from residential area

and campsites, the space are free, so the impact is not

considerable

- The vehicle operators, workers directly involved in the field

of construction, some households in Ban Ang (when leveling

the building of PMU) are mainly affected.

� Sources of pollution, and the level of objects affected by

drilling activities, blasting

- The amount of dust and exhaust gas which is emitted during

blasting is relatively massive. However, by the time it is

blasting, construction equipment must be evacuated safely

out of explosive range (R = 300-400m safety). The amount

of dust and gas does not spread far, mainly 1-3m and

deposited into the ground. In addition, each time landmine

explosion is usually short, the construction area space is

wide open away from residential area therefore dust

exposure level is reduced considerably. The domain impact

is the blasting construction area and quarries. Workers who

25


directly blast and the other workers in the neighborhood are

the main affected object.

� Source of pollution, the extent and objects affected by land

and materials transport processes:

- Total volume of materials used in construction of Ban Ang

hydropower are approximately 258,676.88 tons. In

particular, covering and reinforcing roof rocks are mined in

place, the volume of materials to be transported from other

places are 141, 056 tones. The distance of transport is 30km

(construction materials are purchased in the town of Hoa

Binh)

- The scattered households along the transport route (from

Hoa Binh town to the project area) and the transportative

participants through the project area are the main affected

object

- Scope of impact: 50m from the source.

- The material gathering mostly disrupt, emission gas rapidly

diffuses into space and these effects can be minimized

5 Noise pollution � The level and objects influenced by noise due to blasting

operations

- Instantaneous intensity of blasting noise is up to 95-100dBA

which significantly take effect on the health and life of

workers and residential people.

- Construction workers, people in the surrounding areas, the

species of animals and wild animals living in the forest

nearby blasting area are the core affected objects. However,

blasting activity takes place in a short time (about 0,25s),

usually in the range from 11h30-12h30 and 16h30-17h30

when other construction activities were paused.

� The level and objects influenced by noise due to the

operation of construction machinery

- In a number of areas under construction, noise of working

devices can work up to 80-90 dBA.

- Although the project area have large space, trees, vegetation

will absorb or reflect a portion of noise, but because of the

high workload, the number of machines involved in the

construction are the relatively large so that when the

machinery operation occur simultaneously, resonance noise

will take place

- If there is no noise mitigation measures it will directly affect

the health of employees, reduce the focus ability, increase

energy loss due to physical factors, minimize workers'

reflexion . When the workers expose to high-intense noise in

the long time they will suffer from hearing reduced,

26


occupational deafness, and nerve function disturbances, ...

- Workers who directly participate in the construction,

foresters, traffic participants through the construction area

and the animals living in there are the objects of noise

impact. In regard to Ban Ang households due to the distance

of about 300m to the construction area so the level of noise

impact is not remarkable.

6 Solid waste pollution � Generated source, the intensity and the impact of

construction waste

- The amount of rock excavation is 66.56x103m3. According

to statistics, the volume of solid waste generated from

construction activities such as soil and rock mining, leveling,

excavation and construction work items are accounted for

approximately 0.1% of the total volume of earthworks

execution project (equivalent to 66.56 m3 or 116.48 tons).

- Rocks from disposal areas, storage yards, the construction,

demolition of cofferdam will be entrained flow down Nam

Mo river that increase turbidity and sediment the flow,

decline water quality of Nam Mo River . This is unavoidable

impacts during construction of hydropower projects

- Mostly all households in the Ang and Kien vilages do not

use Nam Mo River water to serve daily activities. Therefore,

the affected object is Nam Mo river water quality and

aquatic ecosystem of this area.

- There are also the leftovers of building materials such as

brick, stucco, metal, dead concrete, packages, plastic, waste

rock, crushed aggregate phase, ... to be estimated as 15 kg /

day. This waste is essentially inert to the environment.

However, if they are not collected, they will cause the area to

lose aesthetic and obstruct river and stream traffic flow in the

region

� The generated source, intensity and impacts of solid waste:

- Generated from the activities of 310 workers ( at peak time),

the main components are: organic matter, plastics, paper,

cardboard, rags, scrap, nylon, plastic bottles, cans…The

amount of waste in rural areas is estimated at 0.3 kg / person

/ night this stage, the total daily emissions are about 93kg /

person/night

- The amount of domestic waste is capable of rapidly

biodegradable, so that it causes unpleasant stench. So if there

is no reasonable measures to collect, it will be the source of

environmental pollution, source of disease for workers,

farmers and animal life surrounding areas.

� Generated sources, and the degree of impact of hazardous

27


waste

- During the construction, an amount of hazardous solid waste

will be released such as wasted or leaked oil during

maintenance of machinery, machine oiled rags, batteries,

damaged batteries, damaged fluorescent optical bulbs ,oil

cans

- The maximum total oil release in one year is 1080 litres ( or

90l/month)

- If leaked waste oil is left on the surface, the rain water will

sweep to pollute surface water of the project area, which is

the pollution source of Nam Mo River’s water quality, and

environmental soil and ground water areas

- Nevertheless this impact is shorterm and completely

mitigated

7 Loss of part

vegetation cover

� 87.74 ha area will be acquired

� The project construction will lose vegetation, reduce the

number of plant species. The vegetation of the project area is

mainly regeneration forest, tree density is quite thick but

perennials are less, forest reserves are not large, forest

quality is not high (ferns, lichens, wild banana, cement, ...),

grass shrubs, in addition to a number of areas and crops such

as rice, corn ...

� Dust which generates from the leveling, blasting, foundation

and access road construction, material transportation will

deposit on leaf leading to reduce photosynthesis capability

of trees in project area.

� Because of project feature temporary land area of auxiliary

facilities is not large. Construction period only lasted 2.5

years. The vegetation will be restored after the construction

phase

8 Impacts of mining

(sand, quarry etc) for

construction project

� Rocks are mined near Ban Ve hydropower, at the

downstream of Nam Mo River, which are distant with Ban

Ang dam about 15km. Because this is an open pit so it is

exploited by surface blasting. Opencast quarrying by surface

blasting need to use industrial explosives, if it does not

comply with safety measures, it will lead to collapsed mine,

affect the lives and property of residents and workers in the

neighborhood

� Sand is mined from the sandbank in Nam Mo River

downstream, transport distance to work is from 1 to 20 km.

Mining method is using pumps to soak directly into the yard

and then transport it to the project site by trucks. If sand

extraction by directly soaked pumps is not authorized and

supervised by local authorities, it will lead to sand depletion,

28


subsidence, landslide of river banks and the surrounding

areas.

� The use of rock explosive materials and sand transporting

process to the project site causes air pollution caused by

dust, gases, noise and vibration

� These impacts only affect workers who directly participate

in exploitation cases along with the households living near

mining area and transportation routes. These effects can be

minimized.

9 Impacts due to

construction of

transmission line and

access road

� During construction, the investor must open and upgrade

about 1.16 kilometers access and internal road; 0.2 km 35kV

transmission line to connect from the project to the national

grid.

� Acquired land and vegetation loss due to access and internal

road, transmission line of the project is not considerable

compared to other hydropower projects

� The construction of roads and transmission line will cause

air pollution due to dust generated in the process of

excavating, construction, toxic emissions from the

construction equipment operation, noise by breaking the

stone, digging foundation, and traffic safety. However, this

impact does not affect remarkably to the community because

the population density is rare and small volume construction.

� The investor has to construct only 0.2 km of the 35 kV

transmission line so this line does not cross the road or

impact to existing transmission /telecommunication lines in

the project area.

� The lines do not cut through any military areas and do not

affect the historical, cultural heritage of Nghe An province

10 Effect to terrestrial

ecosystem

� During the construction process, the following activities will

affect the life of terrestrial fauna

- Using motor vehicles on a large scale and continuously

- Gathering of workers with high density in project site

- Blasting

� The process of building and land occupied by the project

leads to decreased vegetation cover, shrinks the living space

of animals

� Vibration from blasting, rock breaking, operation of

construction equipment will be significantly impact to the

animals living in the project area and in the forest around the

project area. Most of them here have no rare species, such as

birds (kingfishers, lemon ...), mammals, amphibians within

the project area and surrounding area. They will be forced to

29


migrate, find new habitat due to the harassment leading to

reduction of number of species. The remaining species will

have behavioral and living habits change manifest in order

to adapt the changing environment;

� The workers might exploit forestry products, wildlife to use

as fuel, food. The hunting of workers (if possible) will

reduce the number of animals; therefore it will affect the

living of species in the area

11 Effect to aquatic

species and fish

� Due to the specific characteristics of the hydropower project,

the construction of the canal route and dams, river crank ...

will increase the turbidity of the river water at the

construction site, affect to the life of fish , aquatic plants and

ecosystems of a Nam Mo river’s part running through the

project area and downstream dams of Ban Ang hydropower.

Rocks will cover the habitat, minimize the photosynthesis

capacity, reduce the vision and predatory ability of

freshwater fish, and kill eggs of some species, living in the

Nam Mo River’s section through the construction site. In

addition, the construction of dam will separate living space

of fish between upstream and downstream of the dam,

preventing the customary fish from migrating to upstream to

spawn (fish stature nose). This will reduce the biodiversity in

the region.

� There are three negative impacts that affect life and

reproduction of the shoal of fish and aquatic species: Strong

noise and vibration emanated from the construction

equipment, water quality changed due to oil leakage,

domestic and construction waste. Especially, blasting

operation will destroy aquatic animals in the project area

� Runoff water on the surface pulling the sand will increase

the turbidity in streams, affect lives of plants and animals

underwater : fish, shrimp, crabs, snails, frogs, eels, moss,

algae, ... the project area and surrounding areas; Activity

constructing hydropower projects significant impacts to

regional ecosystems, especially aquatic flora and fauna in the

area. The impact of changes in environmental quality of life

of animals and plants under water only temporary during the

construction period and in the local project area (mainly the

Nam Mo River construction period headwork and plants).

Ecosystem will gradually recover and species diversity will

increase as the project goes into operation stability.

However, changes in water ecosystems by preventing lines,

hydroelectric dams will form two distinct ecosystems

upstream and downstream Ban Ang hydropower dams.

12 Effect to fish and

aquatic life

� Due to the specific characteristics of the hydropower project,

the construction of the canal route and dams, river crank ...

will increase the turbidity of the river water at the

30


construction site, affect the lives of fish , aquatic plants and

ecosystems of a Nam Mo river’s part running through the

project area and downstream dams of Ban Ang hydropower.

Rocks will cover the habitat, minimize the photosynthesis

capacity, reduce the vision and predatory ability of

freshwater fish, and kill eggs of some species, living in the

Nam Mo River’s section through the construction site. In

addition, the construction of weirs will separate living space

of fish between upstream and downstream of the dam,

preventing the customary fish from migrating to upstream to

spawn (fish stature nose). This will reduce the biodiversity in

the region.

� There are three negative impacts that affect life and

reproduction of the shoal of fish and aquatic species: Strong

noise and vibration emanated from the construction

equipment, water quality changed due to oil leakage, civil

waste and construction waste. Especially, blasting operation

will destroy aquatic animals in the project area

� Runoff water on the surface pulling the sand will increase

the turbidity in streams, affect lives of plants and aquatic

species: fish, shrimp, crabs, snails, frogs, eels, moss, algae,

... the project area and surrounding areas.

� Activity constructing hydropower projects significant

impacts to regional ecosystems, especially aquatic flora and

fauna in the area. The impact of changes in environmental

quality of life of animals and plants under water only

temporary during the construction period and in the local

project area (mainly the Nam Mo River construction period

headwork and plants). Ecosystem will gradually recover and

species diversity will increase as the project goes into

operation stability. However, changes in water ecosystems

by preventing lines, hydroelectric dams will form two

distinct ecosystems upstream and downstream Ban Ang

hydropower dams.

12 Effect to traffic � Construction materials are purchased from dealers in Hoa

Binh town, Tuong Duong district, 10 km from the project.

Machinery and equipment are transported from Vinh to the

site along National roads No. 1 and No. 7

� The transportation of raw materials and machinery at peak

times might affect traffic on National road No.7's segment

from the project to Hoa Binh town, Tuong Duong district

without appropriate coordination

� Traffic accidents can happen to people on the roads

transported raw materials, machinery and equipment for the

project due to the operation of heavy trucks, super-critical

cars. This effect can be minimized if traffic safety's

31


regulations are complied with.

13 Effect on cultural/

historical properties

� During the survey process , after working with Luu Kien and

Xa Luong commune and combining with public consultation

, it is showed that the project area does not have the cultural

and historical relics ranked or under right of district and

province People Committee ... The result is no cultural and

non-cultural property and related to ethnic minority

� The project has developed implementation plans in case of

detecting the monuments of cultural history ... in the process

of building

14 Effects to natural

preservation area/

national park

� The project area does not lie within the range of natural

protected areas and national parks. It is distant with the

buffer zone of Pu Mat National Park 11km to the north, the

buffer zone of Pu Huong Nature Reserve 59km to the west

15 Risks of mine and

underground works

� During project construction, It might risk from unexploded

mines and remnants of war

� During construction, the project must use mine for

excavating of the main items of works such as dams,

factories ... If the construction of underground works, use of

explosives do not comply with security measures, dangerous

accidents, health and lives of workers and the local

population affection will happen.

OPERATION PHASE

16 Change of flow in

downstream

� Ban Ang hydropower is within Ca hydropower cascade

which is downstream of Nam Mo Hydropower therefore Ban

Ang hydropower operation mode depends on Nam Mo

procedure

� Because of the type plant project located adjacent to the

dam's foot; hence water used for power generation will be

returned immediately to mainstream dams so that there will

be no influence released from cutting off the flow diversion.

� In the upstream of the dam, hydrological regime of the river

is replaced by the hydrological regime of the reservoir. The

flow rate of water flowing into the reservoir is slower from

the natural flow of Nam Mo River. The water level is higher

than water level of Nam Mo River when there is no reservoir

from 8-10m according to design of the normal water level

and death water level. Thanks to the abundant water

resources, drought and water shortage in the region's dry

season has been partly improved

� In the downstream of the dam, the flow rate, the water level

of Nam Mo river depend on the flow discharge of the dam.

On the dry season or when the day and night flow is less than

32


the minimum flow through the turbine, the plant perform

water storage in off-peak hours and discharge water for

power generation during peak hours so the Nam Mo River

dam section will be in short in off-peak hours. In flood

season, when the daily average water flow is greater than the

designed flow, a large amount of water will be retained for

electricity generation, excess water will be spilled over the

dam so that water level in downstream of the dam will be

lower than natural water level in the flood season of Nam

Mo river, hence it partly limits downstream flooding.

� Approximate 6km downstream from the project site to the

confluence Both people still use the Nam Mo River water for

agriculture and aquaculture should an investor need to

comply with the procedures for regulating reservoir does not

affect downstream water use in the dry season peak

17 Impairment on water

quality

� If solid waste activities, workers’ domestic sewage,

industrial wastewater containing grease generated from

greasy operations, machinery and equipment maintenance

are not managed well, it will cause Nam Mo river water

pollution. However, this effect is not remarkable and can be

minimized.

� According to EIA’s calculation, total biomass remaining in

the reservoir is estimated to be 90 tons, while storing water,

this biomass will be arsorbed leading to reduced level of DO,

increasing level of BOD5 , degrading water quality, affecting

life of underwater flora and fauna. This effect can be

minimized if the investor makes good clearance work.

18 Impacts on flora � The formation of the reservoir, water srorage for Ban Ang

hydroelectric power will contribute to improve the

microclimate conditions of the area in a positive way. Along

with the formation of the reservoir, air humidity of the area

also increases, the air temperature is well conditioned than

when there is no reservoir, create good conditions for

vegetation, trees grow.

19 Impacts on fauna � After the formation of a stable reservoir, small animals

(civets, weasels, foxes, mice ...), birds, reptiles and

amphibians ... tend to go back to living in the area near the

reservoir.

20 Impacts on fish and

aquatic species

� After the formation of the reservoir, a new ecosystem,

aquatic ecology reservoir will form new fauna and flora.

Aquatic system of project area will change from an aquatic

ecosystem to adapt to water aquatic lake systems

� The plankton: The first year of storing plankton groups such

as algae are dominant. Along with the development of

phytoplankton, zooplankton system also flourish with

33


shellfish, shrimp. Zooplankton density will be higher than

the current

� The benthos: About 5 years after the beginning of new

wetlands, unstable substrate, molluscs groups will decline in

both species composition and quantity. When the bottom

begin to stabilize, group of molluscs are capable of

developing back and only distributed in shallow coastal

waters, the soft bottom sediments

� Fish fauna: During first years of water storage, the fish prefer

flowing waters, preferred spawning migration will be

reduced in number, the floating fish species such as carp

would thrive ...

21 Noise � The operation of 2 units with total installed capacity of 17

MW and a number of other devices such as oil pump will

cause noise ...

� Based on the experience from other hydropower plants, Ban

Ang hydropower is a kind of behind dam, not the one that

uses differential high pressure water column , so that the

noise is not considerable (about 80 dB at 1 m position) . This

will meet QCVN 26: 2010/BTNMT national noise technical

standard

22 EMF � Power Plant: Operation of electrical equipment such as

generators, transformers will generate an electromagnetic

field. Electromagnetic field affects only the workers

operating the equipment if they do not comply with adequate

procedures and regulations for operating electrical

equipment. Effects of electromagnetic fields do not affect the

community as people stay away from the plant and these

impacts could be reduced

� Transmission Line: If the line operation does not comply

with the regulations for the power grid safety corridors, it

will affect public health due to the influence of magnetic

field lines, especially the one who live or work below the

wire in unsafe distance. The statistics show that with the

power grid safety corridors, electromagnetic field intensity

will be less than 5kV/m, which meets WHO standards.

Moreover, the transmission line is 200 meters long and there

is no people live or work under this line so the influence is

insignificant

23 Emergency case � Dam break incident: Flow and the tide of flood exceeds the

maximum water level according to design (P = 1%); Because

flood forecasting is not accuracy so the plant operation is not

prompt when flood happen; earthquake excitation, but this

possibility is not high. Upon the occurrence of a break in the

total amount of water stored in dams (2,977 million m3) will

34


overflow downstream, causing artificial floods, damaging

life and property of the people. This disaster cause serious

consequences leading damage to health and life as well as

assets especially in downstream area. This disaster is

analyzed and focasted in dam safety report.

� Fire incident caused by electric shock: During the operation,

electric shock or fire might happen due to transformer

malfunction of electrical distribution stations ... it will cause

casualties to the operator and economic damage to the

investor.

� Labor accident: It will happen when workers do not comply

with the safety regulation during the equipment repair and

maintenance. Occupational accidents might cause workers

casualties and damage the investor’s property

� This problem can be minimized if they strictly comply with

regulations on labor safety, fire prevention and reservoir

operation

PREPARATION AND CONSTRUCTION PHASES

1 Impacts to

communities

� Though the project do not have to carry out resettlement,

but withdrawal of productive forest land, land for

perennial crops of 83 households will put pressure

change on production practices and disturb people's

lives.

� People in the project area is largely ethnic with

backward customary; therefore the change of the project

will affect the livelihood of some ethnic minorities

households

� The process of transporting raw materials and

machinery for the project may affect traffic section 10

km from Hoa Binh town, Tuong Duong district to the

project construction especially at peak time if the

vehicle coordination is unreasonable.

2 Shuffling ordinary life

of the community

because of the worker's

appearance, conflicts

between construction

workers and local

people

� It is estimated that at the peak of construction there will

be approximately 300 staffs and workers involved in

� Due to the small population density, therefore the effect

is not considerable

� It is expected to layout 3 separate auxiliary camps at the

right bank, upstream and downstream of the dam, away

from Xa Luong residential area

� Relationship between the developer and affected people

living in areas are good. He has experience in managing

workers, maintaining security and order in the area when

building the other projects before.

� Security situation of Xa Luong commune, Tuong Duong

district are rated quite satisfactorily, social evils like

drugs, robberies, fights are rare ... so the possibility of

conflict between workers and local people is low.

3 Increase livelihood and � Since the construction, the site will attract a large

income for people

living in adjacent to

project area

number of workers; create jobs and income stability for a

segment of the population in the region.

� Ensuring food need and a variety of other necessities for

the field will provide opportunities for production and

commercial service activities for the inhabitants in

development project area.

OPERATION PHASE

4 Positive impact on

local socio-economy

� Completed project will provide local the stability and

high quality power

� The construction of Ban Ang hydropower project will

also contribute to restructuring the economy from

agriculture to industry and service, increase production

of the local industry, create jobs and expand other

economic activities, gradually improve people's lives in

project area

� Tax revenue from water resource also supplement the

provincial budget

� The reservoir may allow the development of aquaculture

in the future, create more jobs and income for workers.

5. MITIGATION MEASURES FOR NEGATIVE IMPACTS

During construction phase, the contracts will be signed between developer and

contractors who construct internal roads, switchyard and transmission line, main

components such as dam, powerhouse etc. These contractors will sign the subcontracts

with the sub-contractors who provide material/equipment. The responsibilities of

developer/contractors/subcontractors who must comply with mitigation are presented in

Table 5.1.

The mitigation measures must be put into the bid documents/contracts by

developer/contractors as requested conditions to the material provided/constructed

contractors. The Nam Mo-Nam Non hydropower company also signs contract to

construction supervision consultant. The CSC is responsible for monitoring EMP

implementation of contractors. The TOR for CSC is presented in the Annex 2. Nam Mo-

While monitoring the scene if supervising/monitoring environmental officers discover

that there is non-compliance with regulations on the implementation of measures to

minimize environmental impacts mentioned in EMP then monitoring construction

staff/ environmental supervisor shall make the records and report the investor .The

investor will stop paying that month expense for the contractor until the contractor

performed adequate measures to minimize environmental effects. The contractor will

be extended one time (due to the construction supervision consultant / supervisor of

environmental regulate) to correct this violation. If the contractor performs the repairs

within the time extension he will not be penalized. However, if the contractor does not

conduct the repairs needed in the extension period, the contractor will have to pay for a

third party to repair the damage (this cost will be taken from retained). Investors must

make provisions for compliance and sanctions for environmental violations in the

contract with the contractor.

In case supervision staff / monitoring environmental officers find non-compliance with

the environmental regulations of the contractor, the contractor shall have to pay the

cost to repair the violation.

The investor is responsible for monitoring and implementing the EMP effectively. If

he does not fulfill the implementation of the EMP, the slow disbursement from the

project to the investors will happen

Environmental offices of the contractor will be the place to receive complaints from

citizens against environmental influences such as dust, noise, traffic safety, The

Contractor’s Chief Engineer and Personnel Assistant with the safety and environment

officers will be responsible for carrying out or giving solutions to handle the above

issues. Officer safety and environmental construction supervision consultant (or team

management environment of the investor) will be provided with copies of the

complaints of the people and must confirm that the problems are properly resolved by

the contractor in a similar incidents were discovered when examining at site.

10. PUBLIC CONSULTATION AND DISCLOSURE

10.1. Public consultation

In the preparation phase, Nam Mo-Nam Non JSCo carried out the following

tasks

1. The feasibility study report and investment report of the project were submitted to

communal People Committees of Luu Kien, Xa Luong. Based on the comments

from above local authorities on locations of the main components, the developer can

revise promptly project documents to get effective investment and mitigate

compensation, migration, resettlement and impacts on environment and

communities.

2. Social survey by interview directly representatives of local authorities and affected

households was done by developer. Results from these investigations show that

almost households and local authorities support to construction of project since it

provides benefits for local residents. Project also facilitates for local traffic from

internal roads.

3. Survey and statistic of environmental impacts as well as affected households were

done.

4. Preparing EMP report

5. Consultation meetings on EMP report and other related issues were held at the

offices of Communal People Committees of affected communes included Xa Luong,

Luu Kien from 18-19 August, 2014. Participants consist of representatives from

developer, local authorities and households of Luu Kien, Xa Luong communes, EMP,

EP, RP consultants, (Minute of meetings and list of participants are presented in the

Annex 3). The main content of consultation meetings as below:

Developer presented the main information of project

� Ban Ang small hydropower project has the capacity of 17 MW, annual average

power output is 68,51 million kWh, is categorized as impoundment, regulated

by reservoir. Catchment area: 3,829 km2 normal water level 85 m, dead water

level: 83m; reservoir capacity: 2,977 million m3 . Reservoir area corresponding

to normal water level: 0,481 km2; the dam length is 122m, the dam climax placed at 90.5 m altitute ; Maximum flow: 145.56 m3/s; ensured flow 16.3 m3/s.

Ban Ang hydropower project is under small hydropower master plan that was

approved by Nghe An provincial people committee.

� Construction of Ban Ang small hydropower project as the same other ones will

cause some negative/positive impacts to environment and social and these

negative impacts are unavoidable. EMP is prepared following to the World

Bank safeguard policies and commits to complying to mitigation measures so

that the negative impacts could limit. Developer also develops CDM for Ban

Ang hydropower project and hope to have support from local authorities as well

as residents for project

Environmental consultant presented generally the environmental

negative/positive impacts and mitigation measures which will be applied by developer

during project implementation as below:

77

Positive impacts:

� When finishing, project will supply stable power with high quality for the local

people. It will support to development of industrial, handicraft and traditional

sectors in the locality

� During construction and operation phases, project creates jobs for local people

� After formation of reservoir, climate in the project area becomes cooler with

higher humidity that facilitates for development of vegetation cover, trees and

reservoir aquatic species such as fish, snail, shrimp etc. The reservoir could

allow aquaculture to develop in the future which provides new jobs and income

for local residents

� Income from tax of water resource usage which is provided from project will be

added to provincial budget

� Project has installed capacity of 30 MW with annual electricity production of

68,51 million kWh. Project also applied CDM and as estimated the certification

emission reduction is received around 42000 ton of CO2 per year

Negative impact:

Construction and operation of project must block river, storage water, build the

main components such as dam, penstock, powerhouse, switchyard, transmission line

etc that cause some unavoidable impacts as below:

� 78 ha land will be appropriated permanently for building components of

headwork and 6 ha land will be acquired temporary for auxiliary facilities

� Construction activities of components of headwork such as dam, spillway,

intake, penstock, powerhouse and swichyard have to excavation of soil/rock

that cause landslide/erosion at these sites

� Process of blocking river, constructing dam bringing about increasing turbidity

and reduction of water quality of Nam Mo river.

� Activities such as blasting, excavation of foundation, quarry, leveling soil and

rock, material transportation, rock grind, concrete mixing, operation of

constructed machines, construction etc will impact to environment causing air

pollution in case the mitigation measures are not applies.

� In the construction phase, the operation of constructed/transported facilities,

concrete mixing, rock grind, blasting, using driller etc will create noise that

disturb to local residents

� Constructed and domestic solid waste that discharged from workers will cause

pollution of air and Water River if it is not well controlled

� In the construction phase, the aquatic species may lose temporary living

condition due to reduction of surface water quality that cause by random

spilling or rain sweeping away concrete, petrol, oil, gear, soil, rock etc.

However, this is only temporary and negligible impacts. They may be mitigated

because project has small scale and the construction time takes only 2.5 year.

78

� Storage of water in the reservoir as well as operation of Ban Ang hydropower

plant will cause changing of Nam Mo river flow regime from behind dam to

downstream of powerhouse. In the project site, rive flow regime will replace by

reservoir hydrography regime that performs by fluctuation of water level. In the

operation phase, the reservoir has negative impacts to aquatic species and fishs

which have habit of emigration. This affect is unavoidable when construction

and operation of hydropower projects

Some key main measures to mitigate negative impacts

Environmental consultant presented briefly draft EMP which will be complied by

developer to mitigate negative impacts with some key measures as below:

� The permanent and temporary acquired land due to project construction will be

compensated following compensation plan which is approved by local

authorities. During construction phase, cultivate and public transportation

acquired land for campsites, transmission line and auxiliary facilities will be

limited by contractors

� The contractors are responsible for inform to local authorities and residents on

blasting time so that they do not travel or release cattle in the blasting areas.

� Disposals have to meet criteria: far from surface water at lease 100m, do not

affect to surface water, cultivate land, do not locate on the risk of erosion,

should locate on the hollow sites to mitigate sweep away by runoff water.

� To establish the worker code at construction site containing regulations such as

prohibiting workers to discard domestic/construction waste into surrounding

areas, river, stream or places which may sweep away to surface water.

� Do not allow to burn solid waste to mitigate risks of forest fire.

� After construction phase, the mine, borrow pits or disposals etc must be

restored by leveling ground then planting trees to prevent erosion.

� Planting trees and controlling vegetation cover at reservoir surrounding area

especially in the places of semi-flooding, main components for more stability of

ground

Developer commits to comply with EMP with the main issues presented above

Questions and answers are summarized as below:

Luu Kien commune:

Questions from representatives of local authorities and affected households

Chairman of Luu Kien PPC committee: Support to develop Ban Ang project. Beside

the positive impacts the project also has some negative impacts such as landslide at

river bank (breakwater in front of PPC commune office was constructed already). The

landslide will be impulse when formation of reservoir. Request to promote process of

compensation for affected households.

Mr. Toan, the chairman of Kien village: Questions about measuring flood level

(elevation) the slot region Nam Mo River water which will flood hydroelectric

impoundment lake and the land and crops of residents in coastal areas but that slots are

not counted therefore he requires the investor and land officers measure and

79

recalculate that area. The inventory of land and assets on land of people are still

missing, hence he requires counting again. He also asks to provide information on

compensation rates for residents. It is necessary to consider the problem of landslides

in crop positions in coastal areas when hydro lakes formed

Mr. Long: Taking into consideration the issue of resettlement and manufacturing

sector, he requires to create jobs and according to statistics there are 62 affected

households and moreover the defining issues as immigration and resettlement ,

problems with local inhabitants: flooding can cause erosion and he ask to create

bulkheads to prevent erosion

Mr. Phu: He agrees with the construction of hydropower Ban Ang, he asks about the

impact of flooding by hydroelectric power (in flood season water does not flow down

into low areas due to dams in the area of plant hence reservoir of hydropower's water

level will rise higher then inundate people in the region). The regional waste of Luu

Kien commune conventionally disposed in this river now will be dammed and stuck in

communal areas.

Others: Questions about problems to coastal inundation level of hydropower reservoir,

landslide problems and safety corridors of reservoir area, the identification of flooded

land and compensation requiring the appearance of village's leader.

Reply from developer and consultant:

Regarding the erosion concern: the construction of hydroelectric projects inevitably

creates erosion. In EMP report, it is proposed the measures to minimize erosion, and

the developer undertakes to comply.

Regarding the idea of compensation level and time: the investor has built the

compensation plan passed by the local government. Moreover, during the demarcation

process of determining compensation, local government also participate in. The level

of compensation is performed according to regulations of the state. If there are

complaints about the tests, the investor will coordinate with communal authorities and

the affected households to tackle. For information about compensation rates, developer

will provide it to the affected households through local government

Regarding issues related to creating jobs for people: the developer would like to

acknowledge and try to arrange jobs for locals in the permitted conditions. Issues

related to stability of life for affected people, the developer has built compensation and

resettlement reports, and commit to comply.

Regarding waste issues: the developer has proposed measures to manage and minimize

the effects of waste during construction and operation of the plant. He commits to

adhere to mitigate this impact.

Xa Luong commune:

Communal authorities and people's opinion: Chairman of Xa Luong commune: The

project occupies an area of about 15-16 hectares of Xa Luonng commune's area.

Occupied land has three main purposes: forest land, livelihood land and agricultural

land in which agricultural land accounts for about 4-5 ha. Ban Ang hydropower project

will not affect remarkably the coastal areas and a few grazing households. The

appearance of workers has a positive impact (trading activities, the exchange of goods,

creating jobs in place for local people, contributing partly to regulate the flow and

80

reduce flood,). However it also creates negative effects (rising social evils and garbage

and construction waste) to the social economic and environment of the commune.

Opinion of communist party secretary of Xa Luong commune: He agrees with the

principle of building Ban Ang hydropower plant. Project might affect crops, grazing,

and fishing of people in the region. Compensation schedule will stretch as other

hydropower projects

Mrs. Thin (land official): requires the investor to make environmental claims.

Moreover, she wants to know about: Transportation of concrete, materials in the

bridge area is far about 5km from the project affects Highway 7 and arise dust to

people in the roadside. Waste dumping in concrete areas affects region of Nam Mo

River. The discharge of hydropower plant affects the area below the Nam Mo River .

Questions regarding the land compensation rates in the upstream and downstream

project area under the 2013 land law

Mr. Luong Van Chau agrees with the construction of Ban Ang hydropower and states

some impact on the lives of people as the problem of drug addiction and social evils. H

e also represents about : Impacts on the fishing in the area of Xa Luong commune,

people in the reservoir area due to water discharge at the dam area. He asks questions

about measuring the level of flood area in the project area, determining the elevation,

and developer needs to provide information on issues of land and land assets

compensation

Mr. Luyen: Regarding the issue of construction of Ban Ang Hydro Power Plant:

protect Ban Ang relics, satisfactorily resolve the issue of compensation for land and

assets on land (pressing concerns about slow settling compensation in Khe Bo

hydropower)

Reply from developer and consultant:

Regarding comments relevant to the social evils caused by high concentration of

workers, the developer acknowledges and has mitigation measures outlined in the

EMP and will commit to manage workers carefully to limit this impact.

Regarding the impact on grazing of a number of households, investors have taken

measures to minimize such as prescribe blasting time, build the signposts to inform the

construction area, avoid grazing livestock into the project area, therefore he hopes that

local people show empathy and cooperate with the developer to ensure no unfortunate

accident.

Regarding the compensation level and schedule: The developer have established

compensation project based on the regulation of the State and accepted by the

communal authority

Regarding comments related to fishing downstream of the plant as well as the

environmental impact during the construction phase, the developer would like to

acknowlegde and establish mitigation measures and commit to comply with EMP to

minimize those impacts.

6. Editing EMP with considered the recommendations of people and affected

communal government in the community consultation meeting as well as in the

investigation of affected households.

81

7. Sending EMP to Luu Kien and Xa Luong communal committee to ask for

recommendation

8. Editing EMP according to the comments

10.2. Disclosure

As policy of WB’s disclosure, developer will implement steps as below:

Annex 2: Responsibility of construction supervision consultant

The Target

The CSC supports the EMP efficiently during the Ban Ang hydropower construction

To achieve the target of diminishing the environmental negative impacts of the project,

the contractor needs to comply with this management plan. Therefore, implementing

him environmental management plan will relate to the following units:

The safe and environmental supervising officers of the contractor are responsible for

supervising the EMP and problems about safety and environment of the construction

The safe and environmental supervising officers of CSC is responsible for the

construction inspection and guarantee that the contractor will comply with the requests

in the contract and EMP

Tasks:

Overall responsibilities of the safe and environmental supervising officers including

supervision and inspection of construction activities to ensure that the mitigation

measures are implemented as appropriate in the plan so that environmental

management and the negative impact of the project on the environment is diminished.

The contractor is responsible for ensuring compliance with the environmental

management plan of the project and the contract conditions during construction under

the supervision of safety and the environment officer. Therefore, safety and the

environment officer is an independent supervisory personnel to ensure compliance

with the environmental management plan and ensure the full implementation of the

contractor for environmental issues

Personnel monitoring and environmental safety will examine monitor and implement

the environmental review for tenders and contracts for road construction. Supervisors

on safety and the environment have much knowledge and experience in monitoring

and verification of environmental issues and advise investors on implementation issues

of the project environment project. Personnel monitoring and environmental safety

should be familiar with the project work through the review of relevant reports,

including the report on environmental impact assessment (EIA) Trung Thu

hydropower project, environmental Management plan as well as the relevant technical

standards and contract documents.

Being a part of the construction examiner group, safety and environmental staff is

obliged to the following tasks

Phase 1: Preparation

The objective of Phase I is taking foundation for successful implementation of the

project. During this period, supervisors, safety and environment must: (i) consider the

DTM, environmental management plan, project design and technical standards to

assert not to miss these mitigation measures ; (ii) prepare guidelines for contractors in

the implementation of Environmental Management Plan; and (iv) develop and

implement training programs for activities related to construction.

Main tasks for this phase are:

85

Desk study: supervisors on safety and the environment will review the DTM,

environmental management plan, project design and technical standards and certify in

writing expressly not to omit any mitigation measures. If problems arise, safety and

environment officers propose to the investor for additional updates in the

environmental management plan, project design and technical standards of this issue.

When the Investors, Board of Management and the World Bank project GDoE ratify,

personnel monitoring and environmental safety will conduct additional updates

environmental management plan

Environmental supervision directory: The safety and environment officers need to

create an examination directory during the construction for supervising the

implementation of the contractor. This includes the core issue of the project, the

requested mitigation measures and implementation plan

Diary: safety and environment supervising staff of the Contractor shall keep diaries to

record events or changes possibly implicate the assessment of environmental impact

and non-compliance attached to the proposals. Diaries must be always ready to serve

when the supervisory staff support as mentioned in the environmental management

plan and contract suggest. Safety and environment staff of the investor will verify this

diary.

Environmental training : Environmental safety staff of the investors are obliged to

design and implement a comprehensive training program for the Supervision Engineer,

Owner, environmental safety officers of the contractor (and workers as part of training

for supervisors, safety and environment), the environmental requirements of the

project and methods for monitoring and evaluation, especially should pay attention to:

Environmental management plan: the requirements of the Environmental Management

Plan, approved check list in supervising environmental, environmental sample

monitoring and processing methods for non-compliance with the management plan

environment and all the issues will be mentioned. Special attention should be paid to

the specific terms of the contract emphasized on compliance with the environmental

management plan

Health and safety: Health and safety requirements of the project must be apparently

verified and coordinated to the contractors and the investor (included in the technical

standard environment for the contractors

At the end of training, the contractor will sign a confirmation through training grasp of

environmental regulations, the environmental management plan and compliance

framework, on the health and safety obligations. Construction supervisors must sign

the certification through training understand the oversight responsibilities.

Phase 2 Construction activities supervision

Safety and environment officer of the investors will represent the Owner and

monitoring Chief Engineer:
