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
Impacts Impact description
- 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
Impacts Impact description
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
Impacts Impact description
- 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
Impacts Impact description
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
Impacts Impact description
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
Impacts Impact description
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
Impacts Impact description
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
Impacts Impact description
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
Impacts Impact description
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
Impacts Impact description
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
Impacts Impact description
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
Impacts Impact description
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
Impacts Impact description
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

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.

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
