2.3. Construction method

Material, equipment:

Lao Cai Renewable Energy (Vietnam) Joint Stock Company will hire contractors

to build main work items such as dam, tunnel, intake gate, powerhouse,

switchyard, transmission line, access-internal roads. Rock after excavation of dam

foundation, powerhouse foundation, tunnels will be gathered to storage sites

which are approved by local authorities. This rock will be grinded to reuse for

project construction. It is estimated that around 68,100m3 of rock will be used

for project in which 37,500m3 of rock will be reused from excavation of dam

and powerhouse foundations and underground works. The shortage of rock will

be purchased from dealers in Lao Cai city or Sa Pa district. Sand, cement, steel,

iron, and construction material will be bought at Lao Cai city or Sa Pa districts

which are around 20 km far from project site. The volume of materials will be

transported by batch in accordance with the construction schedule.

Transportation:

Access road: Access road of project is very convenient. The National road No.4D

is mainly used as access road (Lao Cai - Lai Chau direction) then go along the

communal road at Coc San commune to project site. The developer must

upgrade 2 km of this road as access road.

Switchyard and transmission lines:

Electricity supply system for construction will be taken from 35 kV voltages

transmission line nearby construction site. Besides, the backup 200 kV diesel

generator is arranged at dam site in case cut-off electricity.

Project has to build 798m of 110 kV transmission line which connects from

switchyard of power plant to the existing national grid (110 kV Lao Cai – Phong

Tho transmission line) at Lai Chau province.

Construction organization:

The Coc San hydropower project is expected to take 2.5 years to completion of

construction phase. Activities of excavation/backfilling of soil/rock at all project

20

components, placing large grain size concrete at dam, placing concrete at

spillway are done in dry season while steel reinforcement, on-site formwork at

powerhouse and penstock is implemented in rainy season

Water supply: Water for construction is taken from Dum River. Domestic water

is taken from slots of small streams then filtered by man-made tanks before

using.

Campsites and auxiliary facilities:

There are about 300 workers on site at peak time. 2 campsites with the area of

about 1,800 m2 are arranged at the downstream of dam. These camps are

installed solidly and have water filtration tanks and septic toilets. The auxiliary

facility with area of 4,000 m2 which is arranged at the dam site, auxiliary blocks

No. 1, 2, 3, 5, and 6 consists of steel shuttering, form-work shop, fitting shops,

TT Impacts Impact description

PREPARATION AND CONSTRUCTION PHASE

1 Land acquisition Acquired land for project construction: 52.94 ha

20.33 ha for reservoir

19.66 ha for main components such as penstock,

tunnel gate, underground adits No. 1 and 2,

powerhouse, switchyard, access road etc.

12.95 ha for campsites, disposals, material

storages for project construction.

The whole of acquired land is located in

communes of Coc San, Tong Sanh, Bat Xat

district and Trung Chai commune, Sa Pa district,

Lao Cai province. Share of land use consists of

agricultural land, cultivated forest land, stream and

river land, fallow land with bush, bamboo and

bald land etc.

(Refer Table 4.2 for more detail)

Impact assessment: there is not any household has to

resettlement, a compensation plan needs to prepare to

ensure the interests for impacted households, and the

negative impact is average.

2 Landslide, erosion and

sedimentation

Cause of landslide/erosion

- Construction activities of headwork such as

spillway, penstock, underground No. 1 and 2,

powerhouse, switchyard etc. need to

excavation/backfilling leading to expose of risk of

landslide/erosion at these sites.

- Process of landslide can be increased when

construction of dam and storage water in reservoir

especially at unstable ground. Furthermore, in case

of long, heavy rain and water level rising, the new

land is submerged leading to partial landslide

Project features:

- The geological feature of Mong Sen dam route is

accessed quite well. The left foundation of

powerhouse is stable. In general, work geological

condition of energy route including penstock,

powerhouse in the left side is best.

- Mong Sen reservoir is located at Mong Sen bridge

area, downstream of confluence of Ngoi Dum and

Ta Phin streams. Reservoir is mainly formed base

on stream bed and expanded toward right side so

gentle slope (100-20

0) while the left side is

mountain side with high slope (300-40

0).

- Along to Dum River from Sa Pa to Coc San

powerhouse area, the landslide phenomenon is

frequent occurrence because of high slope of

mountain sides (300-45

0). Coc San powerhouse site

usually experiences landslide. The landslide

phenomenon in vegetation cover and weathered

rock often happens during rainy season.

- At the Coc San powerhouse area on the right and

left sides of Dum River, landslide phenomenon

often occurs at cliff which is along National road

No. 4D and two sides of Ngoi Dum banks at

altitude of +120.0 - +300.0 with the length of 100-

200 m.

In case of exploding mine or excavation of

foundation leading to loss of gravity balance, new

landslide is possible at the powerhouse site which

has high sloping terrain. The contractor should

pay attention when construction and strict

monitoring at the sites exposing to risk of large

landslide so that could apply appropriate

mitigation measures.

Impacts of landslide/erosion:

24


- Sedimentation of Dum River and reservoir

- Reduce water quality

- Changing of water flow in downstream

- May damage to life and assets of workers or local

people nearby

Impact assessment: Average negative impact if do

not comply strictly mitigation measures of

landslide/erosion.

3 Impacts on surface

water quality

The main reasons cause to water surface pollution

in the construction phase:

- Domestic waste water from 300 staffs/workers in

project site (at peak time).

- This type of waste water contains BOD5, residue,

TSS organic substance etc.

- In average, each worker uses 31 water litters per

day. If the domestic waste is 80% to the usage

water, the average sewage of 300 workers will be

24.8 m3 per day.

- Wastewater discharging from activities such as

concrete mixing, rock/vehicle/road washing,

vehicle/machine maintaining etc. Wastewater and

run-off water from these sites will cause pollution

of surface water of project area.

- The wastewater from auxiliary facilities contains

highly alkaline concentration. It increases the

alkalinity of Dum River water and nearby streams

if it is directly discharged into these surface water

resources,

- Run-off water runoff often sweeps a large amount

of mud/soil, spilled concrete, waste etc...so it has

high concentration of solids and other impurities. It

causes increasing turbidity in downstream of Dum

River leading sediment deposition in streams’ slot

in the region, affects to life of aquatic plants in

streams and Dum River downstream. If spilled

gasoline, solid waste and construction activities are

not properly managed, this type of waste will

negatively affect to surface water when workers

directly discharge waste to streams and reservoir...

Organic waste from the decomposition of animals

and plants when storing water of the reservoir.

Impacts of surface water pollution

- Increasing of turbidity, reducing of water quality of

25


Dum River water.

- Affecting to life of aquatic species

Project features:

Investigation result at project site and downstream

area shows that almost households living in the

surveyed area do not use Dum River water for

domestic usage. They take water from slots of

stream in the mountain to each household by

pipes. The impacts mentioned above do not much

impact to life and human health of local residents.

Decreasing of volume of Dum River water will

negatively impact to cultivation and aquaculture

of downstream. However, this impact only occurs

in the construction phase and can be mitigated.

Impact assessment: average negative impact if do

not comply strictly mitigation measures.

4 Air pollution Causes of air pollution:

- Blasting for construction of internal road, digging

of foundations

- Rock/soil excavation and backfilling

- Material transportation

- Operation of rock grinded/screened stations;

concrete mixed workshops;

- Operation of vehicles; constructed

machines/equipment

- Construction of main components.

For above items, main tasks need to carry out as

below:

- Excavation/backfilling of rock/soil: 1,147.9 x 103

m3

- Concrete works: 73 x 103 m

3

Calculation of estimated dust quantity is emitted

from excavation and backfill activities:

- Total quantity of excavation and backfilling:

1,147.9 x 103 m

3 x 2 ton/m

3 = 2,295.8 x 10

3 tons

- Total dust quantity emits during excavation and

backfilling: 2,295.8 x 103 tons x 0,4 kg/ton =

918.32 x 103

kg

Dust is also strongly emitted from road

construction parallel with activities of rock/soil

excavation and backfilling; material/rock/soil

26


transportation; blasting for digging foundations

The dust concentration which emits in project site

may be exceeded the permission if do not apply

mitigation measures.

Besides, the operation of constructed machines,

trucks will emit toxic gas such as CO2, CO, SO2,

NOx, dust

Sand, rock, cement, steel for project construction

will be bought from dealers at Lao Cai city or Sa

Pa district which are far from project site around

20 km. As estimated,

materials/equipment/machines that serve for

project construction is transported in sequence

along National road No 4D, internal communal

roads to project site.

All main works are quite far from internal

communal roads. There is not any public work

including road/irrigation works in project site.

Dust and toxic gas pollution emitted from

construction phase only impact to environment in

narrow space, partial, short-term and depending on

construction time.

Air pollution impacts directly to workers who

work in the construction site and communities of

Coc San commune if no appropriate mitigation

measures are applied.

Transportation of construction material, machines,

equipment will emit dust and toxic gas causing

pollution to residents who live two side of road

during transportation.

Impact assessment: negative average impact in short-

term.

5 Noise Main causes of noise pollution:

- Operation of constructed facilities

- Operation of materials/equipment transported

vehicles

- Operation of concrete mixed stations, rock

grinded/screened workshops

- Blasting, using drilling machines

According to statistic data: 8-12 tons loaded trucks

have the noise level of 91-98 dBA; excavator: 90-

96 dBA; air pressed driller: 94 dBA.

As calculation, the average noise level of

27


machines/equipment is around 72-80 dBA in the

distance of 120-200 m. Comparing to QCVN

26:2010/BTNMT, this noise level affect to workers

who are working directly 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 nearest distance from project site to household

nearby is 500 m. Due to all works is quite far from

communities and noise only occurs in certain daily

time so the noise only impact to workers who work

directly in the construction site.

Impact assessment: average negative impact and in

short-term. This impact may be controlled if

applying appropriate mitigation measures.

6 Pollution cause by solid

waste

Sources of solid waste:

- Dump rock/soil from construction sites, material

transportation and discarded rock/soil from

excavation, drilling, blasting etc.

- Scattering concrete: from concrete mixed stations,

constructed sites, concrete scattering in

transportation process

- Scattering steel: from constructed sites and

productive workshops

- Wood, bamboo: from constructed sites, reservoir

- Domestic solid waste: from campsites, constructed

sites

During construction phase, discarded rock/soil will

be discharged from excavation of topsoil, reservoir

vegetation clearance, from excavation of

foundation serving for construction, 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, tin waste. It may

cause unpleasant odor in case of not well

http://www.ziddu.com/download/13098522/39_2010_TT-BTNMT.rar.html


28


controlling.

In case if clearance of reservoir does not well

leading to disintegrate animals/vegetable bodies

that causes surface water pollution.

Impact assessment: average negative impact, short-

term, could be mitigated if appropriate mitigation


7 Loss of partly vegetation

cover

Total acquisition land for project is around 52.94

ha

Since the terrain feature of project site is high

mountain and hill with high slope so the vegetation

here is not diverse. Almost the lost vegetation for

project construction is brush, grass 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...

Impact assessment: Low negative impact because

vegetation covers does not diverse with low

economic and preserved value.

8 Impacts of mining (sand,

quarry etc.)

Soil backfilling for project construction is mainly

used for embanking small dyke and road

construction. The volume of soil using for project

is not much so it is estimated that this soil will be

reused from foundation of works, no need to

quarry.

Rock is reused from excavation of foundation of

dam, tunnel, powerhouse and it is screened at site

serving for project construction.

Exploiting rock from excavation of foundation by

blasting on the surface must to use the explosive. It

may cause accident at work due to trench collapse

leading to death/wounded of workers or asset

losses in case if contractors do not comply with

safe regulations.

Blasting for exploiting rock 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 exploiting site

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

29


mitigated.

Impact assessment: average negative impact and

can control by appropriate mitigation measures.

9 Impacts due to

construction of

transmission line and

access road

During construction, the developer has to upgrade

about 2 km internal road; 798 km 110 kV

transmission line to connect from the project to the

national grid.

Construction of internal roads and transmission

line may cause the following impacts:

- Acquired land must be required for these activities

leading to losing a part of vegetation. The

vegetation cover of project area does not diverse,

mainly bald hill/mountain, brush, grass, partly

agricultural trees such as paddy, maize, cassava

etc.

- The terrain of project area is mainly hill/mountain

with high slope 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. There is not any

household nearby project site so landslide does not

effect to houses however, landslide or soil/rock

that are swept away to farm will effect to

cultivation.

- Acquisition land is not much. Developer only

acquires small land to build 6 high tension poles

and clearance of vegetation cover for transmission

line corridor to ensure space enough and to comply

with the transmission line safeties, protected

corridor. The length of access and internal roads is

only 2 km. There is not any resident living in the

project area so this impact is small comparing to

other hydropower projects.

- Construction process of 110 kV transmission line

and internal road will cause air pollution by dust

emission during excavation/backfilling of

soil/rock, toxic gases exhaust from operation of

vehicles/machines, noise by blasting, digging

foundation and effect to transportation safety.

These impacts are not remarkable.

- 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/telecom signal

for local area or expose to risks of electrical

accidents for workers or residents. However, the

30


length of transmission line is only 972 m so these

impacts are small.

- The transmission line does not cross the army areas

and effect to the historical/cultural monuments of

Lao Cai province.

- Terrain of project area is mainly sloping

mountain/hill so it may expose to risks of

damaging to health or life of workers/local

residents if the safe measures are not applied

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/flood

season.

Impact assessment: average negative impact and it

can be controlled by appropriate mitigation

measures.

10 Effect to terrestrial

ecosystem

Transportation activities in project site may divide

the moving lines of some animal species which is

living in the project site.

Construction activities and land occupation by the

project may cause decreasing of vegetation cover,

and reducing of 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 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;

Almost of animals fear the noise so the noise from

construction activities such as blasting, rock

breaking, operation of machines will impact to

animals who is living surrounding project area.

Most of them here have no rare species, mainly

bird, small animals (dog, fox, reptile etc.). They

will be forced to migrate, find new habitat due to

the harassment leading to reduction of number of

31


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

Impact assessment: Low negative impact and it

could be controlled if appropriate mitigation


11 Effect to aquatic species

and fish

Due to the specific characteristics of the

hydropower project, the construction of the energy

route and dams etc. will increase the turbidity of

the stream water at the construction site, affect to

the life of fish, aquatic plants and ecosystems of a

Dum River’s section which runs through the

project area and downstream Coc San hydropower.

Rocks will fill up the habitat, minimize the

photosynthesis capacity, reduce the vision and

predatory ability of freshwater fish, and kill eggs

of some species, living in the Dum 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

and reduce the biodiversity of species in the

region.

The strong noise and vibration from machines,

changed water quality because of oil leakage,

domestic and construction waste may negatively

impact to life and reproduction of fish and aquatic

species. 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;

Construction activity of hydropower project

impacts significantly 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 phase and in the partial

project area (mainly at the section of the Dum

River that build headwork and power plant).

Ecosystem will gradually recover and species

32


diversity will increase as the project goes into

operation stability.

Impact assessment: low negative impact due to

capacity of recovery of ecosystem when project

will be put into operation.

12 Effect to fish and

aquatic life

Construction materials will be bought at dealers in

Lao Cai city or Sa Pa district which are 20 km far

from project site. Machines and equipment will be

transported from Lao Cai city to the site along

National roads No. 4D and internal roads.

The transportation of construction materials and

machines at peak times might affect traffic on

National road No.4D and internal road from Lao

Cai city and Sa Pa district to project area if they are

not be coordinated appropriately.

Traffic accidents can occur to people who travel on

the roads because of operation of heavy trucks.

This effect can be minimized if traffic safety's

regulations are complied with.

Impact assessment: this impact is average negative

and short term

13 Effect on cultural/

historical properties

Result from consultation with authorities and

communities of Coc San, Tong Sanh communes,

Bat Xat district and Trung Chai commune, Sa Pa

district showed that there is not any cultural and

historical relics ranked or under management of

district and provincial People Committee or

cultural and non-cultural property related to ethnic

minority

The developer has developed implementation plans

in case of detecting the monuments of cultural

history ... in the process of building

Impact assessment: low negative impact

14 Effects to natural

preservation area/

national park

The project site is not located within the natural

preservative areas. The project site is 40 km far

from the Hoang Lien Son – Sa Pa National Forest

towards Southwest.

- Impact assessment: no negative impact

15 Risks of mine, fire,

chemical spilling and

building of underground

works

During construction phase, large volume of

materials must be mobilized for building of dam,

reservoir, energy route etc. It is forced to use

explosives, oil, petrol etc. In case if do not comply

to security measures it is easy to expose risk of

exploding, spilling out of oil, petrol cause of forest

fire, vegetation destroying, pollution of air, water,

33


soil as well as land slide danger or labour accident

by blasting.

Impact assessment: average negative impact if do

not comply strictly labour safety measures.

OPERATION PHASE

16 Change of flow in

downstream

Coc San hydropower project is under the cascade

of Dum River including 3 power plants namely

Chu Linh, Coc San and Coc San Ha. Coc San

project is downstream of Chu Linh project. Up to

now, Chu Linh and Coc San Ha projects have not

been built.

Coc San project is categorized of headrace, daily

regulation so around 6 km length of downstream of

dam may be dry.

In dry season:

- When storing water in dam, around 6 km length of

downstream from dam to powerhouse will be dry.

- Coc San project uses daily regulated reservoir so in

dry season water from upstream of Dum River will

be storage in dam. Water then is taken through

underground tunnel to penstock and turbines to run

generators. Thus, the 6 km length of stream section

will be partially shortage of water since they will

not receive water from upstream.

- However, based on the 1/10,000 scale map, in the

area of 6 km length there are 5 branches of Dum

River with quite high flow rate which supplement

water to this area event in dry season.

- Due to the climate of Northern region of Vietnam

is rainy and humidity in the spring so dry season

usually lasts about three months from November

last year to January next year

- The affected stream section is located in the

sloping terrain with many big rocks therefore the

aquatic species cannot live here. In the other hand,

there are not any households and agricultural

activities in this section.

- In spite of reduced flow in dry season, the flow is

maintained at least of 0.55 m3/s through discharged

gate. This flow can ensure the minimum volume of

water for aquatic ecosystem of this section.

In the rainy season:

- With presence of reservoir, a part of coming water

is stored in the reservoir to the normal water level

34


for power generation and the remaining is

discharged through spillway.

- Due to abundance of water in the rainy season so

change of water flow (water is kept in the reservoir

and then transferred to penstock) in the dry stream

section not affect to life of aquatic species.

- Natural flow: the increase of water flow only

affects to the stream section which locates from the

dam to the powerhouse. However when running

through the winding streams, velocity of water is

strongly down and it nearly returns to the natural

status without the powerhouse.

- Practices from the same projects show that a new

ecosystem is formed in this stream section and it

can adapt to the drier environment.

Regarding the section of downstream behind the

powerhouse:

- The flow is still maintained when water is kept in

the reservoir in both dry and rainy seasons so the

aquatic ecosystem will not be affected remarkably.

- Storing water in the reservoir for electricity

generation not affects to water demand of local

people in downstream since they normally take

water from the higher region for their domestic

water usage.

- The water demand of local people is not much

since low population density and stream water is

not used for agricultural and fishing activities

- Fishing depending on the Dum River’s natural

flow of downstream is generally not much affected

due to the flow through the turbines is still

maintained at 0.996 m3/s in the dry season. This

flow ensures to maintaining the environmental

flow in the downstream during low peak hours in

dry season.

- In closing, changes in flow rates, water levels and

environmental impacts only occur in stream

section which is located from behind dam to the

powerhouse. However, modification in the

downstream is not noticeable because the winding

of Dum River will lessen these impacts strongly.

Impact assessment: average negative impact since

the reservoir only regulates daily with Qtk = 7.2

m3/s, Qđb = 0.996 m

3/s and always maintain the

environmental flow of 0.09 m3/s for dry section

after the dam.

35


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 Dum

River. However, this impact is not remarkable and

could be mitigated.

In the first time of filling water, water quality

depends on result of cleaning up the reservoir. If it

is well done, pollution of water will be mitigated.

On the other hand because it is daily regulation

hydropower project (storing water and generating

electricity about 5 peak hours a day) so retention

time of water in the reservoir is short. Biomass

was not long soaked in the reservoir which

can frequently exchange water. Therefore, biomass

is slowly decomposed. Water is not polluted as the

larger reservoir which has long retention time of

water.

Experience from similar projects showed that after

about 1-2 years, the quality of the water will return

to the original status without pollution.

Impact assessment: low negative impact if

complying strictly with mitigation measures.

18 Impacts on flora - The formation of the reservoir, water storage for

Coc San 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

In the early years of flooding, aquatic life is

basically the group of organisms including algae,

siliceous algae, crustaceans etc. They appear

dominantly among the floating creatures.

Density of floating creatures is higher comparing

36


to the bottom ones. In dry seasons, density of

floating creatures is lowest in the upstream area. It

is highest in the area nearby upstream and reduces

gradually toward the downstream.

In the flood season, the density of floating

creatures is lowest in the upstream area, highest in

the area near the dam and rising gradually in

downstream.

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 ...

Impact assessment: average negative impact if


21 Noise The operation of 3 units with total installed

capacity of 29.7 MW and a number of other

devices such as oil pump will cause noise ...

Based on the experience from other hydropower

plants, Coc San hydropower is type of is

categorized of headrace, 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

798 meters length and there is no people live or

work under this line so the influence is

37


insignificant



23 Emergency case Dam break incident: The reasons of breaking dam:

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 (231.6 x 103 m3)

will 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 forecast 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 developer.

Labor accident: It may occur 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

Impact assessment: average negative impact since

the frequency of accident is low. However, the

responding plans should be prepared carefully and

the training plan should be done yearly.

1 Impacts to communities

Although the project does not require

resettlement, but withdraw of productive forest

land, agricultural land and land for perennial

crops of 116 households will put pressure change

on production practices and disturb people's life.

People in the project area is mainly ethnic people

with backward customary; therefore the change

of the project will affect the livelihood of some

ethnic minorities households

The process of transporting materials and

machinery for the project may affect traffic of

Relationship between the developer and affected

people living in areas is good. Developer has

experience in managing workers, maintaining

security and order in the area when building the

other projects before.

Security situation of Coc San commune, Bat Xat

district is quite good, social evils like drugs,

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

Company carried out the following tasks

1. To submit the feasibility study report and investment report to communal

people committee of Trung Chai, Sa Pa district, communal people

committees of Coc San, Tong Sanh, Bat Xat district with the purpose of

consultation on location of main components of project. Depending to the

comments, the developer can revise project documents to save cost, mitigate

compensation, resettlement as well as reduce impacts on environment and

community.

2. To survey by interview directly representatives of local authorities and

affected households. Result from survey shows that almost households and

local authorities support to construction of project because of its benefits for

local residents.

3. To survey and statistic of environmental impacts and affected households

4. To prepare EMP report

5. To organize the consultation meetings on EMP report and other related

issues at the offices of Communal People Committees of affected

communes including Trung Chai, Coc San, and Tong Sanh from July 31,

2015 to August 1, 2015. Participants consist of representatives from

developer, local authorities and households of Trung Chai, Coc San, Tong

Sanh 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

Coc San hydropower project has the capacity of 29.6 MW, annual average power

output is 138.87 million kWh, is categorized as impoundment, daily regulation by

reservoir. Main parameters: catchment area: 99.6 km2; total of flow rate: 145

million m3; reservoir area corresponding to normal water level: 4.24 ha; normal

water level: 702 m; death water level: 699 m; gross capacity of reservoir: 252.3

million m3; useful capacity: 124.6 million m

3; designed flow Q tk: 7.83 m

3/s, ensure

flow Q đb: 0.996 m3/s, voltage level: 110 kW.

To build Coc San 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 with mitigation measures.

The consultant presented the environmental negative/positive impacts and

mitigation measures which will be applied by developer during project

implementation as below:

79

Positive impacts:

Project will supply stable power, high quality with the total power output of

138.87 million kWh/year for the local people when project is put into

operation. It will support to develop industrial, agricultural projects in the

locality.

Formation of reservoir will facilitate for development of vegetation cover,

trees and reservoir aquatic species such as fish, snail, shrimp etc.

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

be added to provincial budget to support increasing living standard of local

residents.

Negative impact:

Construction and operation of project must block stream, storage water, build

dam, underground tunnel, penstock, powerhouse, switchyard, transmission line etc.

that cause some unavoidable impacts as below:

37.78 ha land will be acquired permanently for formation of reservoir, dam

and building of headwork and 18.2 ha land will be acquired temporary for

auxiliary facilities among them 8.25 ha land is forest.

Construction of road and headwork must excavate/backfill soil/rock that

cause landslide at these sites

Blocking stream to build dam will impact negatively to stream water quality

by increasing turbidity.

Activities such as blasting, excavation of foundation, leveling soil/rock,

material transportation, 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,

machines, 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 stream 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

years.

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:

80

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

compensated following compensation plan which is approved by Decision No.

4197/QD-UBND dated December 9, 2009 issued by Lao Cai people committee.

During construction phase, cultivated and public transportation acquired land

for campsites, borrowed pits; transmission line 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 must meet criteria: far from surface water at lease 100m, do not affect

to surface water, cultivated land, do not locate on the risk of landslide, 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, stream or places which may sweep away to surface water.

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

After construction phase, the borrow pits or disposals etc. must be restored by

leveling ground then planting trees to prevent erosion.

To arrange petrol, oil storages at least 300 m far from surface water,

communities.

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

Questions and answers are summarized as below:

Coc San commune, Bat Xat district:

Questions from representatives of local authorities and affected households

- Construction of project will impact negatively to surface water quality. The

breeding fish may get disease leading to low growth causing by high turbidity

of water.

- Some households lose all the cultivated land since land is acquired for

construction of project.

- The local people could not breed cattle in flooding land when reservoir is

formed.

- The developer should speed up the process of compensation so that effected

households could stabilize their living.

Answers from developer and consultant:

- Regarding to impact of surface water quality and aquaculture the impact of

surface water quality is unavoidable during construction of

hydropower/irrigation projects. However, this impact is short-term and only

occurs during construction phase especially blocking dam. This impact may be

mitigated if developer complies strictly with mitigation measures presented in

EMP. In the operation phase, this issue will be rehabilitated gradually. The

formation of reservoir will impact positively to aquaculture of local community.

81

- Regarding to acquisition of cultivated land and compensation: The acquisition

of cultivated land is not avoidable when building hydropower projects.

Developer prepared compensation plan following Vietnam regulations and it is

approved by local authorities. The compensated rate is depended on the current

regulations. For Coc San project, cultivated land of some households has been

acquired so their income and livelihood will be impacted negatively. Developer

also prepared EP, RP to support affected households on livelihood caused by

project building.

- Regarding to impact on cattle breeding of some households, developer will

apply the mitigation measures such as informing of blasting time, installing of

work signals to prevent accessing into work sites. Developer hope to get

supporting from local people to ensure the accidents will not occur.

Tong Sanh commune, Bat Xat district:


- In general, the communal authorities and residents support to build project.

Construction of project will provide some benefit for local people such as

upgrading of a part of internal road. However, construction process will cause

pollution of water resource, dust etc. Developer should pay attention to deal

with this issue.

- Requested developer increases the compensation rate so that the affected

households does not handicap by project.

- During construction phase, activities of excavation/backfilling, road building

will impact negatively to water resource of local people such as block of water

pipelines that take water from stream to households. Request the developer

solves this issue.

- Request the developer provides the jobs for local people. At present, the

number of local jobless youths is quite high. Developer should arrange jobs

from power plant for them when it will be put into operation.

- Activity of transportation of constructed material will cause pollution of dust

that impacts to local people who are living nearby the roads. Developer should

apply the mitigation measures to reduce dust.

Answers from developer and consultant:

- Regarding to question of environmental pollution: as presenting by consultant,

construction of project will impact negatively to surrounding area such as

pollution of dust, water resource etc. Developer prepared EMP and tries to take

mitigation measures proposed in EMP. During construction phase, developer

suggests the local people to contact the local authorities and environmental staff

of project if project causing pollution. The developer commits to deal with

pollution.

- Regarding to question of increasing compensation: developer prepared

compensation plan and it was approved by local authorities. The local

authorities also participate in process of identifying the compensation boundary.

The compensation rate is in accordance to governmental regulations. If there is

any complaint on account, developer will coordinate to communal authorities

82

and affected households to solve further. Regarding to information of

compensated price, developer will provide to affected households through

communal authorities.

- Regarding to question of providing jobs for local residents: developer records

and try to arrange jobs for them in our permission conditions.

- Regarding to question of blocking water pipelines of local people: developer

records and commits to rehabilitate them.

Trung Chai commune, Sa Pa district:


- The compensation plan has been approved; request developer improves the

compensation progress so that affected households could stabilize their living

soon.

- Construction of project acquires quite lot of forest land and impacts to life of

local people such as they will not breed their cattle, lose benefit from forest

land, requested that developer support to local people.

Answer from developer and consultant:

- Regarding to question of improving progress of compensation: developer

records and commits to coordinate to communal authorities to solve this issue

to support affected households stabilize their life.

- Regarding to question of negative impact of local people by losing of forest

land: developer records and we prepared EP, RP to support affected households

on their livelihood so that they could stabilize their life soon. Developer expects

that local residents support to construction of project.

Target

The CSC supports the EMP efficiently during construction of Coc San hydropower

project.

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) Coc San 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

Objective of Phase 1 is to make 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:

86

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

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

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

environment officers propose to the investor for additional updates in the

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

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

personnel monitoring and environmental safety will conduct additional updates

environmental management plan

Environmental supervision directory: The safety and environment officers need to

create an examination directory during the construction for supervising the

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

requested mitigation measures and implementation plan

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

record events or changes possibly implicate the assessment of environmental impact

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

when the supervisory staff support as mentioned in the environmental management

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

diary.

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

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

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

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

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

Environmental management plan: the requirements of the Environmental Management

Plan, approved check list in supervising environmental, environmental sample

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

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

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

management plan

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

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

standard environment for the contractors

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

environmental regulations, the environmental management plan and compliance

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

the certification through training understand the oversight responsibilities.

Phase 2 Construction activities supervision

the Environmental Management Plan / not conduct operations as directed the

supervisor of environmental safety.

Review of the plan at site: To ensure the consistency throughout the project, safety

and the environment staff must consider the entire plan could affect the environment.

These plans include, but are not limited to: plan pits and dumps. Supervisors on safety

and the environment will be considered and approved the environmental management

of the project and plans to restore the landscape of the contractor. What parts of the

plan does not comply with the environmental management plan, environmental impact

assessment, personnel and environmental safety of the investors will work with the

Chief Engineer and the Contractor to take appropriate measures.

Health and Safety: To ensure consistency throughout the project, the environmental

safety officer must consider the entire safety plan of the contractor, and on the basis of

this plan, with the data of the investor's input, to create a comprehensive plan for

safety projects. Comprehensive Plan about project safety must include processes such

as blast management and safety in the construction process, preventing landslides / soil

erosion during the rainy season, these plans must be reviewed on an annual basis and
