2.3. Construction method

Material, equipment: Trung Thu hydropower joint stock company hires contractors

to build main components of project such as dam, powerhouse, penstock,

switchyard, transmission line and access-internal roads. Material for construction

project such as concrete, steel, fuel, lubricant etc is bought from shops which are

around 30 km far from project site. Sand is mined at place which is 10 km far from

the project site on the upstream. Rock for construction is reused from excavation

for foundations and mined from 2 quarries which are 1,5km and 500 m far from the

dam on the left side.

Transportation:

Access road: The National road No.6 is mainly used as access road (Tuan Giao -

Lai Chau direction). It takes around 2-3 km from National road No.6 to project site

belonging to Trung Thu commune, Tua Chua district and Pa Ham commune,

Muong Cha district.

Internal road: developer has to upgrade and construct new roads as below:

Internal road for construction/operation: from National road No.6 belonging to Pa

Ham commune to the downstream of dam left shoulder with the length of 3.3 km,

6.5 m roadbed width, asphalting structure.

Internal road for construction consists of 5 distances (i) from internal road No.1 to

auxiliary facilities of headwork; (ii) from internal road No.2 to explosive storage;

(iii) from downstream of dam right shoulder to dump-site at downstream of dam

right shoulder; (iv) from upstream of dam right shoulder to dump-site at upstream of

dam right shoulder; (v) from internal road No.1 to sand mine. Total length of this

road is 3.7 km, 5 m roadbed width, reused stone structure.

Switchyard and transmission line: electricity for construction is supplied from 35

kV national transmission line at Trung Thu commune. The 35/0.4 kV transformers

are provided at construction/auxiliary areas. The switchyard with altitude of 238.5

m locates on upstream powerhouse, the right bank of Nam Muc river. The site with

large, raised terrain is convenient for construction activity in both dry and rainy

seasons.

Developer has to build newly 15 km length of 110 kV transmission line from Trung

Thu switchyard to 110 kV Tuan Giao - Muong Lay transmission line which is

connected to Lai Chau hydropower plant to connect to national grid.

22

Construction organization: It may take 2.5 years to completion of construction

phase. Activities of excavation/back-filling of soil/rock at all project components,

placing large grain size concrete at dam, placing concrete at spillway are done in

dry season while steel reinforcement, on-site form-work at powerhouse and

penstock is implemented in rainy season.

Water supply: Water for construction is taken from Nam Muc river. Domestic water

is taken from slots in the higher regions and wells then filtered by man-made tanks.

Campsites and auxiliary facilities: There are around 300 workers in the

construction site at peak time. Four campsites with area of 2 ha at the upstream of

dam on the left side are arranged that are quite far from Nam Muc river bank. These

campsites are provided wells, water filtered tanks, septic tanks. The concrete mixed

stations, form-work shop, rock grinded/screened stations, electro-mechanical

workshop, car parking areas, petrol/fuel storage etc with the area of 5 ha are

arranged at the upstream of dam on the left side. The rock reused storage with area

of 0.82 ha locates at upstream of dam on the left side. Two disposal areas of 4.84 ha

are arranged at right bank, upstream and downstream powerhouse. The explosive

storage locates separately and quite far from other auxiliary facilities, on the left

bank, at the end of internal road No.2.

PREPARATION AND CONSTRUCTION PHASE

1

Land acquisition Total area of acquired land for project is 302.64 ha

Permanent acquired land is 290 ha of which:

243.37 ha for reservoir

46.63 ha for main components such as headwork, intake,

penstock, powerhouse etc

Temporary acquired land:

12.64 ha for campsites, auxiliary facilities such as

disposals, material storage

The whole of acquired land is located in Trung Thu

commune, Tua Chua district and Pa Ham commune,

Muong Cha district, Dien Bien province. Share of land

use consists of cultivated forest land (long term trees),

agricultural land (paddy, cassava, and short term crops),

bush, bamboo and bald land etc.

(Refer Table 3.2 for more detail)

2 Landslide, erosion and

sedimentation

Cause of landslide/erosion:

Activities of excavation/back-filling of rock/soil at the

main components of headwork such as dam, spillway,

intake, penstock, 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.

It is compulsory to blasting for construction of 7 km

length of internal road due to sloping mountainous/hill

terrain. Risk of landslide is easy occurred during

blasting.

Geological features of project site:

Geological structure of region consists of Nam Pia

terrigenous formation. Petrographic composition

includes shale, quartz.

There are four faulting systems in the region namely

Northeast Southwest, Northwest Southeast, sub latitude

and meridian. The faults have dimension from IV to V

level. The impact of these faults is small. Essential

geotectonic activities are mainly lifted-down activities

simultaneously which create by terrace and alluvial flat

with small dimension.

26

No

Impacts

Impact description

Geological structure of dam site consists of rocks with

hard degree from weak-average to hard. Reservoir

region includes carbonate sedimentation formation,

shale and bazan rocks.

The whole project region now discover new activity

signs of faults.

The mines with economic worth still have not been

discovered in the reservoir area.

Impacts of landslide/erosion:

Sedimentation of Nam Muc river and reservoir

Reduce water quality

Changing of water flow in downstream

Features of project:

Project site is located on long narrow valley, nearby

confluence of Nam Muc, Nam Mu Rivers and Nam Tau

stream. The biggest characteristic of region is

mountainous/hill terrain with average altitude of 500 m.

Riverbed is narrow and high slope.

Due to quite stable geology at reservoir area so the risk

of landslide at large scale to reform reservoir bank is

limitation.

Reservoir is mainly formed base on riverbed. There is

not high level fault which cut crossing the reservoir so

that mitigation of water leakage into neighbor valley.

Process of landslide as well as reformation of reservoir

bank is small scale. Process of sedimentation is

estimated at low speed.

As estimated, speed of natural sedimentation in

reservoir area is low. The reservoir has short length and

large area so the flood area is mainly riverbed without

mountain/hill.

When water is kept in the reservoir, sedimentation

process may occur at low speed because of existing of

Nam Muc hydropower plant and Nam Pay stream in

upstream of reservoir.

Foundations cut through rock layers leading to easy

erosion of foundations.

Discharging water through spillway may cause partially

flood and erosion of area behind the spillway. However,

this area is mainly bald hill and at least 3 km far from

communities so that discharge of water through spillway

27

No

Impacts

Impact description

do not effect to local people.

3 Impacts on surface

water quality

The main seasons cause to water surface pollution in the

construction phase:

o Domestic waste water from 300 workers in project site

(at peak time).

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

and organic substance.

o In average, each worker uses 40 water litters per day.

Total domestic waste water discharge from 300 workers

is 12 m3 per day.

o Constructed waste water from auxiliary facilities such as

machine repaired workshop, concrete mixed stations,

rock washed grounds etc. This waste water contains

mainly TSS, oil and grease, organic substances, metals

etc.

o Run-off water from the whole of project site sweeps out

impurities especially scattered oil, grease, dust which

come from concrete mixed workshops, fuel storage,

machines/equipment/vehicles loading etc.

o Scattered fuel: as estimated, the average volume of fuel

which is extracted from stored tanks to

machines/vehicles is 1,500 liters per day. The loss of

fuel is around 7.5 litters/day (lost norm of 0.5%)

o Domestic and constructed solid waste: in case of not

control well, this waste impacts remarkable to surface

water when solid waste is discharged directly into Nam

Muc river, reservoir.

o Organic waste is decomposed from dead bodies of

animal and vegetation in the reservoir.

Impacts of surface water pollution:

o Increasing of turbidity, reducing of water quality of

Nam Muc river water.

o Affecting to life of aquatic species

Project features:

o Investigation process shows that there are not any

activities of aquaculture or agriculture in project site due

to sloping terrain and low density of population.

o Local people often takes water from the higher regions

for their domestic usage therefore construction of the

project do not affect to water demand and quality water

of local people.

28

No

Impacts

Impact description

4 Impact on air quality Causes of air pollution:

o Blasting for construction of internal road, digging of

foundations, quarrying

o Rock/soil excavation and back-filling

o Material transportation

o Operation of rock grinded/screened stations; concrete

mixed workshops;

o Operation of vehicles; constructed

machines/equipment

o Construction of main components.

For above items, estimated quantity of main works are:

o Excavation/back-filling of soil and rock: 3,150 x 103

m3

o Concrete works: 119.45 103 m3

o Steels of any kind: 1,931 tons.

Estimated dust quantity is emitted from excavation and

back-filling activities:

o Total quantity of excavation and back-filling: 3.150 x

103 m3 x 2 tons/m

3 = 6.300 10

3 tons

o Total dust quantity emits: 6.300 103 tons x 0,4

kg/tons = 2.520 103 kg

Dust is also strongly emitted from quarry and road

construction parallel with activities of rock/soil

excavation and back-filling; material/rock/soil

transportation; blasting for digging foundations.

In comparing with standard of QCVN 05:

2013/BTNMT, the dust concentration which emits in

project site may be exceeded the permission.

Beside, the operation of constructed machines, trucks

will emit toxic gas such as CO2, CO, SO2, NOx, dust

As estimated, materials/equipment/machines that serve

for project construction are transported in sequence

along National road No 6, internal communal roads to

project site.

All main project components including headword,

penstock, and powerhouse are at least 3-5 km far from

residential areas.

Project site is also quite far from inter communal roads.

There are not any households, public works such as

29

No

Impacts

Impact description

irrigation/traffic systems within or near project site.

The quarry which is newly exploited for project is

located far from project site and the nearest

communities at least 10 km and 4-5 km; respectively.

This quarry is separated to the surrounding areas by

hills/mountains that are covered by tree so that the

impact of dust will be mitigated.

Dust and toxic gas pollution which emit in the

construction phase only affect to narrow, partly areas

and in short term depending to the construction time.

Air pollution only affects directly to workers who are

working in constructed sites but not to surrounded

communities.

Dust and toxic gas generated during transportation of

materials/equipment may affect to local people who live

along two sides of roads

5 Noise Main causes of noise pollution:

o Constructed facilities

o Materials/equipment transported vehicles

o Operation of concrete mixed stations, rock

grind/screened workshops

o Blasting, using drilling machines

According to statistic data: 8-12 tons loaded trucks,

excavator, air pressed driller have the noise level of 91-

98 dBA, 90-96 dBA, and 94 dBA; respectively.

As calculation, the average noise level of machines is

around 72-80 dBA within the distance of 120-200 m.

This noise level exceeds the permission following the

standards of QCVN 26:2010/BTNMTso it may affect to

workers who are working in the constructed site.

Noise pollution may cause seriously negative impacts to

workers who hand directly with blasting, using driller if

they are not quipped by labor safe equipment. The noise

level is not only generated by blasting, driller but it is

increased strongly by phenomenon of reverberation in

narrow mountainous terrain.

The main project components are quite far from the

residential areas of Pa Ham and Trung Thu communes

as well as the internal-communal roads. Additionally,

due to the low density of population in the project site

and the noise is only generated in certain daily time,

therefore noise may only affect directly to the workers

30

No

Impacts

Impact description

on the sites during construction and local people who

live along 2 sides of roads during transportation.

6 Pollution cause by

solid waste

Sources of solid waste:

o Scattering rock/soil from quarries, material

transportation and discarded rock/soil from

excavation, drilling, blasting etc

o Scattering concrete: from concrete mixed stations,

constructed sites, concrete scattering in transportation

process

o Scattering steel: from constructed sites and

productive workshops

o Wood, bamboo: from constructed sites, reservoir

o Domestic solid waste: from campsites, constructed

sites

During construction phase, discarded rock/soil will be

discharged from excavation of topsoil, reservoir

vegetation clearance, quarries and constructed waste

containing cement, steel, wood etc. Disposal of

constructed waste without controlling may lead to

trespass forest/cultivated land and water pollution.

Domestic solid waste: 0.3 kg/person/day x 300 persons

= 90 kg/day (at peak time)

Domestic solid waste contains different types of waste

such as food waste, paper, cover of canned food. It may

cause unpleasant odor in case of not well controlling.

In case if clearance of reservoir does not well leading to

disintegrate animals/vegetable bodies that causes surface

water pollution.

The vegetation cover that collected after clearance may

cause risks of forest fire if it is not well controlled.

7 Loss of partly

vegetation cover

Total acquisition land for project is around 302.84 ha.

Since the terrain feature of project site is mainly

mountain and hill with high slope so the vegetation here

is not diverse. Almost the lost vegetation for project

construction is mixed forest such as brush, trees and

agricultural trees such as paddy, maize, cassava etc.

The loss of temporary vegetation cover for disposals,

borrowed pits etc will be restored after construction

phase...

8 Impacts of mining Sand is exploited at mine which is 10 km far from

31

No

Impacts

Impact description

(sand, quarry etc) for

construction project

project site on the upstream. The mine is small alluvial

ground that located along Nam Lay River. This mine is

exploiting by local residents for construction of Nam He

hydropower project. Method of exploiting is suction

pump directly from the mine to borrow pits then

transport by vehicles to project site.

The quarry which is newly exploited for project is

located far from project site and the nearest communities

at least 10 km and 4-5 km; respectively. This quarry is

separated to the surrounding areas by hills/mountains

that are covered by tree so that the impact of dust will be

mitigated.

The first quarry is on the upstream, left side and 1.5 km

far from dam route. The second ones are on the

upstream, left side and 500 m far from dam route. They

are open-cast mines so the method of exploit is blasting

on the surface of mine.

Exploit of sand by direct suction pump may cause

exhaust sand resource leading to depression of river

bank and surrounding areas if it is not permitted and

supervised from local authorities.

Quarry by blasting on the surface of mine must to use

the explosive. It may cause accident at work due to mine

collapse leading to death/wounded of workers, residents

or asset losses in case if contractors do not comply with

safe regulations.

Blasting for quarry and process of transportation of

rock, sand from the borrow pits to project site may cause

air pollution by dust, toxic gases, noise, vibration.

Due to sloping terrain, difficult transportation and

almost none of resident live nearby mines and project

site so these impacts only effect to workers who work

directly in project site and local people who transports

nearby and they could be mitigated.

9 Impacts due to

construction of

transmission line and

access road

The developer has to do following items during

construction phase:

Building newly 7 km length of internal roads

Building newly 15 km length of 110 kV transmission

line from Trung Thu switchyard to 110 kV

transmission line of Tuan Giao – Muong Lay

connecting to national grid.

Construction of access/internal roads and transmission

line may cause the following impacts:

32

No

Impacts

Impact description

Due to high slope so the vegetation cover of project area

does not diversify, mainly mixed forest with brush, trees

and partly agricultural trees such as paddy, maize,

cassava etc.

Acquisition land for road and transmission line is not

much. The transmission line is designed along the

National roads of No. 6 and No. 12 which is complied

with regulations of transmission line corridor safety.

The length of access and internal roads are only 7 km

without local residents living nearby so the effect is

negligible comparing to other hydropower projects.

The terrain of project area is mainly hill/mountain so it

is exposed to landslide leading to risks of health and life

for workers during excavation of pole foundation if the

safe measures are not complied. Because of almost none

of resident living nearby along the transmission line so

landslide does not effect to houses however, landslide or

soil/rock that are swept away to farm will effect to

cultivation.

Construction activities of access/internal roads, 110 kV

transmission line will lead air pollution those causes by

dust during excavation/back-filling of soil/rock, toxic

exhaust from operation of vehicles/machines, noise by

blasting, digging foundation and effect to transportation

safety. These impacts are not remarkable since the

almost none of local communities nearby project site.

The transmission line is dual circuit in which one circuit

is connected to 110 kV Tuan giao switchyard and the

rest is connected to 110 kV Lai Chau switchyard. It

create one closed circuit Tuan Giao-Lai Chau-Trung

Thu hydropower plant so this transmission line will

intersect with existing medium and low voltage

transmission lines and telecommunication cables. It may

damage these lines leading to cut-off

electricity/telecommunication signal for local area or

expose to risks of electrical accidents for workers or

residents. These impacts could mitigate.

Some distances of transmission line will go through the

National/Provincial roads so that it may obstruct traffic

and cause traffic accident during drawing cable.

The transmission line does not cross the army areas and

effect to the historical/cultural monuments of Dien Bien

province.

Terrain of project area is mainly sloping mountain/hill

so it may expose to risks of damaging to health or life of

33

No

Impacts

Impact description

workers/local residents if the safe measures are not

complied during construction.

Project area has low density of population, inconvenient

traffic system. Construction of access/internal roads for

project will facilitate for traffic of residents since the

existing road is earthen, narrow so it is quite difficult,

dangerous for local transportation especially in rainy

season.

10 Effect to terrestrial

ecosystem

During construction phase, the below activities will

cause affects to terrestrial ecosystem:

Gathering of workers with high density in project site.

Access road system is constructed by developer that

facilitates for accessing to project surrounded areas.

Operation of trucks with high frequency

Blasting

The wild animals rarely appear in the project site. There

are only birds, small animals, fox, reptile etc. The above

activities will make the terrestrial fauna trending to

move far away from project site during construction

phase

11 Impacts on fish and aquatic life

The aquatic ecosystem will lose temporary living

environment due to water resource is contaminated by

high turbidity, run-off water contained cement, fuel, oil

and grease rock, soil, etc.

However, these impacts are not remarkable; only occur

in the short term because the civil constructed works are

almost done in the dry seasons.

After construction phase, the presence of reservoir

facilitates for animals to return and live surrounding the

reservoir because of its good living conditions.

12 Effect to traffic Construction material is bought from shops which are

30 km far from project site. Sand mine is 10 km far from

headwork and rock is reused from foundation

excavation and exploited from 2 quarries at left side,

upstream of dam which is around 1.5 km and 0.5 km far

from project site.

Transportation of materials/machines/equipment in

general does not affect to traffic of local people due to

low density of population and travel of communities is

not much.

34

No

Impacts

Impact description

13 Effect on cultural/

historical properties

Results from surveys in the project area as well as

consultation with affected households and local

authorities shows that there are not any ranked

cultural/historical properties which are managed by the

district/provincial/national authorities. There are also not

any cultural and non-cultural properties that relate to the

ethnic minority people in the project area

According to survey, there are 25 tombs in the reservoir

area. Developer is working with affected households and

local authorities to deal with following to regulations. In

case there is any new tomb which is found during

construction phase, developer will coordinate to relevant

stakeholders for resettlement.

The developer prepared action plan in case if

cultural/historical properties are found in the

construction phase.

14 Effects to natural

preservation area/

national park

The project site is located quite far from the natural

preservative areas. The project activities do not impact

to natural preservation parks areas of Dien Bien

province.

15 Risks of mine and

underground works

It may expose risks of mine/bomb during

construction/operation phase that may be left after the

war in case do not detect carefully.

During construction process, the internal roads; 110 kV

transmission line, penstock etc must be built newly.

It is forced to blasting for construction such kind of

works because two sides of streams are mountainous

with high sloping terrain

Process of constructing underground works, blasting

may cause health, life damaged risks to workers and

local people in case safe measures are not complied

OPERATION PHASE

16 Change of flow in

downstream

Trung Thu small hydro power plant is under Nam Muc

cascade. The water level of downstream of Trung Thu

power plant will be affected by regulation regime of Son

La power plant when the water level of Son La reservoir

reaches from 208 m to normal water level of 215 m. The

regulation regime of Trung Thu power plant depends on

the ones of other plants in the same cascade.

A reservoir with the capacity of 30.7 million m3 is

formed after construction phase. Formation of reservoir

and regulation regime of Trung Thu hydro power plant

35

No

Impacts

Impact description

will change the flow of distance Nam Muc River from

behind the dam to downstream. There are two different

flow regimes and their border is dam of Trung Thu

plant. At the upstream of dam, the river flow regime will

be replaced by reservoir hydrological regime with the

fluctuation of water level.

The upstream area of dam, due to project is categorized

impoundment hydropower plant so the water which is

used to generate electricity will be discharged back into

the main river behind the dam so it is not affected by

flow change or breaking off. It does not affect to water

usage of downstream otherwise, it has the positive

impact of controlling flood in downstream area.

The flow regime of downstream area depends on the

regulation regime of power plant. It is not regulated and

generates electricity following additional charge chart.

The variation in day of water level and downstream flow

is not remarkable. There are some small negative

impacts such as landslide, water usage for agriculture,

safety for life and asset etc. To mitigate these impacts,

developer must disseminate widely information on

operation regime of power plant as well as monitor

closely the negative impacts.

The downstream section with distance of 13 km far from

project site to confluence of Nam Muc and Da rivers is

quite sloping so it was not used for water way traffic by

local communities. On the other hand, due to sloping

mountainous terrain of this section, there is not any

households, agricultural/aquaculture activities so project

do not impact to water usage in downstream.

17 Impairment on water

quality In case if the waste such as domestic solid waste,

domestic waste water, lubricant contained waste water

from maintaining machines/vehicles is not well control,

it will lead to pollution of Nam Muc river. However,

this impact is not remarkable and could be mitigated.

When blocking water, if the reservoir is not cleared,

biomass (tree root, regenerated grass, organism death...)

and other substance (humus, mineral salt) which are

immerged in the reservoir will be decomposed leading

to water pollution due to reduce DO and increase BOD5.

Water pollution will cause negative affect to aquatic

life. This impact is negligible and may mitigate if

developer follows fully plan of reservoir clearance.

In case if the amount of phosphoric that discharges into

reservoir is higher 8.15 tons/year, eutrophication

36

No

Impacts

Impact description

phenomenon may occurred leading to reduction of

water quality and affect to aquatic life.

18 Impacts on flora After formation of reservoir, climate in the project area

becomes cooler with higher humidity that facilitates for

development of vegetation cover

For the downstream behind the dam, the flow will be

lower than as the nature leading to loss of water at two

banks of river. The new natural terrestrial ecosystem

will be developed graduate.

19 Impacts on fauna After formation of reservoir, small animals (dog, fox,

mouse...), birds, reptiles, frog etc will come back to live

in the reservoir surrounded area.

20 Impacts on fish and

aquatic species

Increasing to turbidity of water river when construction

project will impact to aquatic species that leave in the

section from project site to downstream of project.

After formation of reservoir, the ecosystem of river

section that becomes reservoir will be changed from

river ecosystem to reservoir ecosystem. The formation

of reservoir has potential of developing aquatic species.

Some new aquatic species will be developed.

In the operation phase, the dam has negative impacts to

aquatic species and fishes that have emigration habit.

This impact do not prevent when constructing and

operating the hydropower plants.

21 Noise The operation of two units with installed capacity

of 15 MW/unit MW and other machines such as

lubricant pumped equipment will cause noise.

As experience from other small hydro power plants,

Trung Thu power plant is categorized as impoundment

power plant but not type of high water column so the

noise is not very high (only around 80 dB at distance of

1 m). This value of noise meets the National standard

QCVN 26:2010/BTNMT on noise.

22 EMF Operation of electrical equipment such as electrical

generator, transformer will arise the EMF. The EMF

only affects to workers who operate the electrical

equipment mentioned above if they do not comply

strictly to regulations on operation of electrical

equipment. The EMF does not affect to surrounding

communities since there is not any residents living

nearby and this impact could mitigate.

37

No

Impacts

Impact description

In case the transmission line does not comply with

regulation on transmission line safe corridor, the EMF

will affect to person who work or living under in the

unsafe distance.

The statistic data shows that the intensity of EMF within

safe distance is less than 5kV/m that meet to WHO

standard on EMF.

23 Emergency case Emergency case in the power house: the electrical

accidents such as electrical leakage, short circuit, fire etc

may occur if do not comply to safe regulations on

powerhouse or electrical equipment operation. These

accidents may lead to damage the power plant.

Emergency case in the switchyard/transformer station:

fire accident due to short circuit/electrical leakage may

occur easily if do not follow strictly technological

design and regulations during construction and

operation. Compliance to procedures on transmission

line safety is extremely important task. It requires

workers have to obey strictly, fully all technological and

safe regulations during operation transmission line.

Emergency case in broken of dam, reservoir: these

disasters may occur in case of extraordinary weather

such as sweep flood or geological altering (earthquake,

crack, depression etc). These disasters cause serious

consequences leading damage to health and life as well

as assets especially in downstream area.

PREPARATION AND CONSTRUCTION PHASES

1 Impacts to communities

There are not any households who have to

resettlement. There are 157 affected households on

land requisition and properties.

Most of people in the affected area are the Thai,

Mong, Kho Mu, Khang, Muong ethnic minorities

who still keep their backward customs so the

project may impacts on their daily life. However,

this disorder only affects few households and it is

only occurred in the construction phase.

39

No Social issues Information

The transportation of materials and equipment

does not affect to the local people since the density

of population here is quite low and most of their

houses are far from the road. The distance from

nearest communities to access road is around 1

km.

Most of the local people expected that

development of project will facilitate to improve

their production and living standards.

2 Labor influx due to

construction workers and

conflict between workers and

communities.

According to feasibility study, there are around 300

staffs/workers that are mobilized for project

construction at the project site in the peak time.

Project site locates quite far from local communities

and internal-communal roads so this impact is not

remarkable.

As estimated, 4 separate camps will be arranged in

the downstream of dam. They are quite far from

residential areas of Pa Ham and Trung Thu

communes.

The relationship between developer and local

people who are living in the affected area is quite

good. The developer has experience in management

of workers and security in the local area when

building the former projects.

The security of Pa Ham and Trung Thu communes

is quite good. The social evils such as drugs, theft

and fight are seldom therefore conflicts between

workers and local people will be mitigated.

3 Increase sources of income

for the local people

At the beginning of construction phase, project will

gather large amount of staffs/workers so that it

could provide jobs and stable income for a part of

local residents in project site.

Demand in foodstuff and a series of services

facilitate for development of production and trading

of the local people.

OPERATION PHASE

4 Positive impacts on the local

socio-economic development

The routes of road which are upgraded and built

newly serving for project construction facilitate for

improving traffic system of local residents. They

help communities more convenient in term of goods

transportation, connecting the project area to other

places such as Tuan Giao town, Muong Lay town,

Dien Bien city etc.

40

No Social issues Information

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.

Income from tax of water resource usage which is

provided from project will be added to provincial

budget.

The reservoir will allow to development of

aquaculture in the future which benefit for local

people in term of getting jobs and improving their

income.

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, penstock, 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 measures 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. Trung Thu hydro power joint stock company is responsible for joining EMP

into detail technical design and construction biding contractor. Trung Thu hydropower

joint stock Company assigned one staff who is in charged in environmental management of

Trung Thu hydropower project. The environmental management staff presides and

coordinates to the relevant agencies to: (i) Monitoring the implementation of mitigation

measures following EMP and EIA; (ii) Supervising, suggesting measures to deal with

negative impacts on environment (if any); (iii) Making report on environmental

management implementation and submit to the district’s Department of Natural resource

and Environment and leaders of Trung Thu JSCo, BIDV Hanoi; (iv) Participating courses

on environmental management which are held by GDoE PMB and WB.

41

Table 5.1 . Key Mitigation and Management Measures

Issues Mitigation and Management Measure

PREPARATION PHASE (Trung Thu hydropower joint stock company is responsible for implementation of mitigation measures)

1. Selection of project location Dam route location is chosen at area where there are not any residents. The dam site is located

at the section of two river banks which has high slope, narrow riverbed with the width of 30-40

m. This section of riverbed has original rock so it facilitates for arrangement of dam route.

Geological feature of the dam route area is disposed by clay and quartz schist with high

mountainous terrain along two river banks.

Selection of project site as presented above may mitigate the negative impacts to environment

due to minimized land acquisition, limitation of loss of vegetation cover, forest, convenience for

construction arrangement etc. It also limits to social impacts of local communities since the

agricultural land acquisition is reduced as well as dam site is quite far from local residents.

Supported facilities of project is chosen based on the criteria such as far from surface water

resource at least 100 m, explosive storage is arranged far from communities with minimum

10. PUBLIC CONSULTATION AND DISCLOSURE

10.1. Public consultation

In the preparation phase, Trung Thu JSCo carried out the following tasks:

The feasibility study report and investment report of Trung Thu project were

submitted to communal People Committees of Sa Tong, Pa Ham, Nam Nen,

Trung Thu, Sinh Phinh, Muong Bang. 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 and impacts on environment and communities.

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.

Survey and statistic of environmental impacts as well as affected households

were done.

Preparing EMP report

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

offices of Communal People Committees of affected communes Sa Tong, Pa

Ham, Nam Nen, Trung Thu, Sinh Phinh, Muong Bang from 16-18 June, 2014.

Participants consist of representatives from developer, local authorities of

communes of Sa Tong, Pa Ham, Nam Nen, Trung Thu, Sinh Phinh, Muong

Bang, environmental and social consultants, affected households (Minute of

meetings and list of participants are presented in the Annex 2). The main

content of consultation meetings as below:

Developer presented the main information of project:

Trung Thu small hydropower project has with the capacity of 30 MW is

categorized of impoundment, regulated by reservoir, annual electricity

production of 124.10 x 106 kWh. The headwork consists of gravity concrete

dam with 252 m length, 45 m height, and spillway with 45 m length. The right

bank energy route includes intake, penstock with 25 m length. Catchment area:

2,759 km2; reservoir area corresponding to normal water level: 30.7 x 10

6 m

3.

The swichtyard is placed at 243 m altitude. Designed flow: 145.6 m3/s;

minimum flow 16.3 m3/s. Trung Thu hydropower project is under small

hydropower master plan that was approved by Dien Bien provincial people

committee.

Construction of Trung Thu 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 Trung

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

as residents for project.

80

Environmental consultant presented generally the environmental

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

developer/contractors during project implementation as below:

Positive impacts:

Around 4.2 km length of internal road and an bridge crossing Nam Muc river

will be built newly serving for project construction facilitate for improving

traffic system of local residents. They help communities more convenient in

term of goods transportation, connecting the project area to other places such as

Tuan Giao town, Muong Lay town, Dien Bien city etc.

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 developing aquaculture 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

124.10 million kWh. Project also applied CDM and as estimated the

certification emission reduction is received around 69,000 ton of CO2 per year.

Negative impacts:

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:

290.2 ha land will be appropriated permanently for building components of

headwork and 12.64 ha land will be acquired temporary for auxiliary facilities.

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

intake, penstock, powerhouse and switchyard 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 Muc 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.

81

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.

Storage of water in the reservoir as well as operation of Trung Thu hydropower

plant will cause changing of Nam Muc 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 fish

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

and operation of hydropower projects.

Some key main 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.

To arrange storehouses of petrol, fuels etc at minimum safe distances of 300 m

from surface water, local communities.

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

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 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 the developer are 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.
