2.3. Construction method

Material, equipments: Total rock demand for project construction is 70.103

m3. This

amound of material will be exploited in the near by mine which located on national

highway No. 43. The total sand demand is 45.103 m

3 which will be produced in rocks

mine and transported to the project site. The Investor has been submited the documents

for license of stone exploition at Khuoi Choong quarry located at the pac Ra village,

Ly Bon commune, Bao Lam district. The intend exploited vollume is around 30,000

m3 and exploited area is 0.5ha, the exploited duration is until 31/12/2015 . The

documents have been submited to Cao Bang DONRE for approval, thus the types and

copce of impacts from sand exploition activities will be updated since the permission

license has been issued.

Other material such as concrete, steel, fuel, lubricant etc is bought from Ha Giang city

with around 102km far from the site or from Cao Bang city with 153 km far from the

project site.

For the imported equipment will be transported by sea ships to Haiphong Port then

carried by trucks thourgh NH 2 and 34 to the site, with total lengh of these route is

500km.


Page 21

Other domestic equipment will be transported by railway or inland waterway/seaway

to Hanoi city then arried by trucks to the project site via NH 2 and 24 with total lengh

is 380 km.

Transportation:

Access road: is the main road being to use in the operation phase and also used during

construction phase.

Temporary road for construction activites: is the main road being to use only in the

whole construction phase .

Temporary road several construction activites: is the road that use for only several

certain construction activites and will be closed since these activties completed. Totol

length of this type of road is 0.8 km.

Swichtyard and transmission line: Electricity supply for main activties on the site

such as equipment operation, worker camps, management house ...with total demand

for consutruction sites is 2MW via 5 transformer stations. Electricity for construction

is suplied from 35kV national transmission line at Ly Bon about 500m far from the

site. The 35/0.4 kV transformers are provided at construction/auxility facilities areas.

Moreover, diesel electric generators with total capacity of 500 KVA will be provided

on the management houses for the case of electricity shutdown from 35kV line.

Electricity grid for construction activities combine transformal and distribution

stations (35/0,4kV), and sublines (0,4kV). 0,4 kV lines will be provided from

35/0,4kV transformers to households. The 0,4 kV lines will only use in the

consutruction phase with simple structures and removablility, foundation by

prefabricated concrete, steel colume 130 mm and 0.5m in height.

Construction organization: Bao Lam 1 hydropower project may take 2 years to

complete the construction phase. The fist year (10/2014 - 9/2015) will focus on

resetlement activities, auxility facilities area preparation, excavation/backfilling and

placing concrete at spillway, dam foundation excavation on right banks. The second

year will focus on dam foundation excavation on right banks, placing concrete at

spillway.

Water supply: Water for construction is taken from Gam river. Total demand of

consutruction water is 700 m3/day.night. Water for fire prevention is 30 l/s. A water

treamant station will be provided at the left hand site of main dam, the water will be

taken from Gam river (at the section before confluence with Nho Que river). The

water after treating will be disbuted to construction site, D = 200mm line will be used

to take water from river to treatment station and D = 50mm line will be used to

distribute water to construction site.

Domestic water supply: Domestic water is taken from slots in the higher regions and

wells then filtered by man-made. Total domestic water volume is estimated around 12

m3/day. night.

Campsites and auxility facilities: Total are of construction site is 8.6 ha, where 7.1 ha

of auxility facilities, 0.4 ha of public areas, 0.5 ha of worker camps and management


Page 22

area. The auxility facilities ussualy will be used in very short time, which constructed

by the temporary structures and material which could be easy for assemble.

3. KEY ENVIRONMENTAL AND SOCIAL ISSUES

3.1. Environmental issues

Table 3-1 Environmental issues of project

No. Impacts Impact description

PREPARATION AND CONSTRUCTION PHASE

1 Land acquisition Total area of acquired land for project is 103.91

ha

Permanent acquired land is 103.91 ha of which:

- 24.09 ha of agricultural land (4.05ha of one

harvest time rice land ), 0.93 ha of residential

land , 12.95 ha of forest product trees and 65.94

ha of other land;

- The whole of acquired land is located in Ly Bon,

Vinh Quang and Bao Toan communes.

Temporary acquired land: to build up worker

camps, disposal sites, and materials field.

(Refer Table 3.2 for more details).

Impact assement: Moderate Negative, but a Rap

will be prerared to ensure safeguard pollicies

application for APs

2 Landslide, erosion and

sedimentation

Cause of landslide/erosion:

- Implementation of excavation/backfilling of

rock/soil at the main components of headwork

such as dam, intake, and powerhouse during

construction phase leading 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 locally landslide.

Geological features of project site:

- Bao Lam 1 hydropower located within the Song

Hien terrigenous formation. Petrographic

compositon includes shale, quartz, lime clay,

pale or ashy adhesive clay, average to shaply


Page 24


faults.

- There are several faults level III cuting through

gristone and sandstone and the stone are

wrinkled and schit. However, these faults is old,

undiscovers new activity signs and no relative to

land movement. These faults have not gone

through limestone formation and fullfill by the

secondary material which ensure that ther will be

not water loss along these faults.

- As in the map scale 1/200.000, Bao Lac (F-48-

X), no high economic value mine have been

discovered in the project areas, there are only

several normal construction material mines.

- The main faulting systems in the region namely

NorthEast-SouthWest, NorthWest-SouthEast,

sub latitude and meridian.

Impacts of landslide/erosion:

- Sedimentation of Gam and Nho Que river and

reservoir.

- Reduce surface water quality.

- Changing of water flow in downstream.

Features of project:

- Project site is located on long narrow valley,

nearby confluence of Gam river and Nho Que

river.

- Suitable geological condition, so the risk of

landslide at large scale to reform reservoir bank

is limitation.

- Reservoir, with small scale, is mainly formed

base on riverbed

- Topography include two sharp slopes from 350

to 400 and faulted. There are not high cascade

and waterfal, low segment vertical in the

riverbed.

- Process of landslide as well as reformation of

reservoir bank is small scale. Process of

sedimentation is estimated at low speed.

- Foundations cut through rock layers leading to


Page 25


easy erosion of foundations.

- Discharging water through spillway may cause

localized flood and erosion in this area (behind

the spillway).

Impact assement: Moderate Negative

3 Impacts on surface

water quality

The main seasons cause to water surface

pollution in the construction phase:

- Domestic waste water from 300 workers in

project site (at peak time).

- This type of waste water contains BOD5, residue,

TSS, and organic substance....

- In average, each worker uses 40 water litters per

day. Total domestic waste water discharge from

300 workers is 12 m3 per day.

- 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.

- Run-off water from the whole of project site

sweeps out impurities especially scattered oil,

grease, dust which come from concrete mixed

workshops, fuel storages,

machines/equipment/vehicles loading etc.

- 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%).

- 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 rivers, reservoir...

- Organic waste is decomposed from dead bodies

of animal and vegetation in the reservoir.

Impacts of surface water pollution:

- Increasing of turbidity, reducing of water quality

of Gam and Nho Que river water.


Page 26


- Affecting to life of aquatic species.

Project features:

- The results from site survey shows that due to

sloping terrain and low density of population

that there are not any activities of small industry,

aquaculture or agriculture in project site. And the

river water in downstream have not used for

domestic or agricultural irrigation purpose.

Impact assement: Moderate Negative in case the

proposed mitigation measure will not be

compliance

4 Impact on air quality Causes of air pollution:

- Blasting for construction of internal road,

digging of foundations, quarrying, due to need

to small realignment (100m) of road from Ly

Bon bridge to Lung Cu, Ha Giang.

- Rock/soil excavation and backfilling.

- Material transportation, loading and unloading.

- Operation of rock grinded/screened stations;

concrete mixed workshops; vehicles;

constructed machines/equipment.

For above items, estimated quantity of main

works are:

- Excavation/backfilling of soil and rock: 926.62 x

103 m

3

- Concrete works: 76.87 x 103 m

3

- Steels of any kind: 3,500 tons

Estimated dust quantity is emitted from

excavation and backfill activities:

- Total quantity of excavation and backfilling:

926.62 x 103 m

3 x 2 tons/m

3 = 1,853.24 x 10

3

tons

- Total dust quantity is generated: 926.62 x 103

tons x 0,4 kg/ton = 370,65 x 103

kg

Dust is also strongly generated from quarry and

road construction parallel with activities of


Page 27


rock/soil excavation and backfilling;

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, and dust.

As estimated, materials/equipments/machines

that serve for project construction are transported

in sequence along Province road No 4C, internal

district, communal roads to project site.

All main project components located very close

with district roads, but keep distance to commune

roads. The project location is only 200 far from

Ly Bon market, which present public facilities

and irrigation system.

The rock and sand supply for project activities

will be taken from rock mine located on the

national road 43, about 7km far from the project

site. 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 not only affects directly to workers

who are working in constructed sites but also

affected to surrounded communities of Ly Bon

commune, if without appropriate mitigation

measures.

Dust and toxic gas generated during

transportation of materials/equipments may

affect to local people who live along two sides of

roads.

Impact assement: Moderate Negative and in the

short time in case the proposed mitigation measure


Page 28


will not be stricly compliance

5 Noise Main causes of noise pollution:

- Construction equipment.

- Materials/equipments transported vehicles.

- Operation of concrete mixed stations, rock

grinded/screened workshops.

- 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/BTNMT so 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 equipments. The noise level is not only

generated by blasting, driller but it is increased

strongly by phenomenon of reverberation in

narrow mountainous terrain.

Due to main project components are located

quite close to residential areas of Ly Bon

commune thus the generated noise may create

negative impact on local people and affect

directly to the workers on the sites during

construction and local people who live along 2

sides of roads during transportation.


short time but the impact could be managed with an

appropriate management plan

6 Pollution cause by

solid waste

Sources of solid waste:

- Scattering rock/soil from quarries, material

transportation and discarded rock/soil from

excavation, drilling, blasting etc.


Page 29


- 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, 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

incase of not well controlling.

In case if clearance of reservoir does not well

leading to disintegrate animals/vegetable bodies

that causes surface water polution.

The vegetation cover that collected after

clearance may cause risks of forest fire if it is not

well controlled..


short time but the impact could be minimized with

an appropriate management plan

7 Loss of partly

vegetation cover

Total permanent acquisition land for project is

around 103.91 ha.

Since the terrain feature of project site is mainly

mountain and hill with high slope so the

vegetation here is poor. 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


Page 30


disposals, borrowed pits etc will be restored after

construction phase...

Impact assement: Minor Negative due to poor

vegetable cover and low valua ecosystem arround

the project area.

8 Impacts of mining

(sand, stone quarry

etc) for construction

The total volume of sand needed for

construction is about 45.103 m

3. Due to no

natural sand quarry, the needed sand will be

grinded from stone quarry then transported to

the project site.

Stone is exploited from Khuoi Choong quarry,

Pac Ra village, Ly Bon commune, Bao Lam

District. The developer is submitting request to

Cao Bang DONRE for exploiting stone at Khuoi

Choong quarry. The intend exploited vollume is

around 30,000 m3 and exploited area is 0.5ha,

the exploited duration is until 31/12/2015.

Embankment soil is mainly for small dyke and

transport roads. All the embankment soil will be

salvaged from the foundation works.

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.


short time but the impact could be managed with an

appropriate management plan


Page 31


9 Impacts due to

construction of

transmission line and

access road

The investor has to do following items during

construction phase:

- Building newly 0.8 km length of internal

roads, include one access road in left bank

and 2 access roads in right bank.

- A 110 kV transmission station will be

constructed on the left bank and connecting

to national grid by 110 kV transmission line.

The 110 kV transmission station intend to

locate about 100m far from Bao Lam 1

hydropower.

Construction of access/internal roads and

transmission line may cause the following

impacts:

- Due to high slope so the vegetation cover of

project area does not diversify, mainly

treeless hill 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 compling with regulations of

transmission line corridor safety. There are

almost none 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/backfilling of soil/rock, toxic

exhaust from operation of vehicles/machines,


Page 32


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 does not cross the army

areas and effect to the historical/cultural

monuments of Cao Bang 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 complied

during construction.

Impact assement: Minor Negative and could be

controlled with an appropriate management plan

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

investor that facilitates for accessing to

project surrounded areas

- Operation of heavy 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.

Impact assement: Minor Negative

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


Page 33


seasons.

After construction phase, the presence of

reservoir facilitates for animals to return and live

surrounding the reservoir because of its good

living conditions.

And the project could be impacted on fishs which

move up or down stream during reproductive

period. For these fishes, the impacts could be on

2-5km before and after dam.

12 Effect to traffic Project needs to realignment about 100 m of road

on left bank which goes from Ly Bon bridge to

Lung Cu, Ha Gang, the realignment activites

could be created impact on the traffic movement

on this road, although the traffic volume is low,

but the PMU also need to develop and apply

appropriate measure to ensure traffic flow and

traffic safety.

Rock and sand material is exploited from mines

and transported via national road 43, about 7km

far from construction site. Other construction

material is boutgh from shops in Ha Giang city

which are 102 km far form project site and rock

is also reused from foundation excavation.

Transportation of mterials/machines/equipments

in general do not affect to traffic of local people

due to low density of population and travelling of

communities is not much.

Increase the worker population on the site also

create high risk of traffic conflicts between

workers and local poeple, if safety traffic

education are not provided for workers.

Impact assement: Minor Negative due to the

recover capacity of ecosystem since the project turn

in to operation phase;

13 Effect on cultural/

historical properties

The Cao Bang Department of Cultural and Sport

had been certificated that there is not any ranked

cultural/historical properties which are managed

by the district/provincial/national authorities in

the project areas. There are also not any cultural

and non-cultural properties that relate to the


Page 34


ethnic minority people in the project area has

been identified during public consultation

meetings

As servey result shows that there is not

concentrated tomb in the project area, but still

there are two graves located in the high places,

over 162m.

The investor will prepare action plan in case if

cultural/historical properties are discovered in the

construction phase.

Impact assement: Moderate Negative in the short

time

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 Cao Bang 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 incase do not detect carefully.

During construction process, the internal roads;

110 kV transmission line, 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.


short time in case the proposed mitigation measure

will not be stricly compliance

OPERATION PHASE

16 Environmental flow in

downstream

Bao Lam 1 small hydro power plant is under

Gam river cascade. Thus the regulation regime of

Bao Lam 1 power plant depends on the ones of

other plants in the same cascade.


Page 35


After construction phase has been completed,

will form areservoir with the capacity of 8.9

million m3. Formation of reservoir and regulation

regime of Bao Lam 1 hydro power plant will

change the flow in downstream of Gam and Nho

Que rivers on the section behind the dam.

The project is categorized impoundment

hydropower plant. 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.

The flow is always maintained at least of 37.1

m3/s through turbines in the low peak hours in

dry season. Moreover, Bao Lam 1 hydropower is

under Gam and Nho Que river basin which has a

munber of stream branches with small flow

adding water to the river.

Impact assement: Moderate Negative due to dail

water monderated operation and the water flow

after dam will be maintained;

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 Gam and

Nho Que river. However, this impact is not

remarkable and could be mitigated.

When blocking water, if the reservoir is not

cleared, biomass (tree roots, 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 to aquatic life. This

impact is negligible and may mitigate if investor

follows fully plan of reservoir clearance.

In case if the amount of phosphoric that

discharges into reservoir is higher 8.15 tons/year,

eutrophication phenomenom may occured

leading to reduction of water quality and affect

to aquatic life.


Page 36


Impact assement: Moderate Negative

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.

Impact assement: Moderate Negative due to the

ecosystem will be seft recover and high adative

capacity with the change of living enviroment.

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

fox, mouse...), birds, reptiles, frog etc will

comeback to live in the reservoir surrounded

area.

Impact assement: Insignificant

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.

In the operation phase, the dam has negative

impacts to aquatic species and fishs that has

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 and other machines such

as lubricant pumped equipment will cause noise.

As experience from other small hydro power

plants, Bao Lam 1 power plant is categorized

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.

Impact assement: Moderate Negative need

preparing an appropriate opration plan to minize

the impacts on local people.


Page 37


22 EMF Operation of electrical equipment such as

electrical generator, transfomer will arise the

EMF. The EMF only affects to workers who

operate the electrical equipments mentioned

above if they do not comply strictly to

regulations on operation of electrical equipments.

The EMF does not affect to surrounding

communities since there is not any residents

living nearby and this impact could mitigate.

- 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.

Impact assement: Minor Negative due to the project

and transmission line (100m) located in the remove

area.

23 Emergency case Emmergency 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.

Emmergency 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

extreamly important task. It requires workers

have to obey strictly, fully all technological and

safe reguations during operation transmission

line.

Emmergency case in broken of dam, reservoir:

these disasters may orccur in case of

extraordinary weather such as sweep flood or

geological altering (earthquake, crack, depression

etc). These disasters cause serious cosequences


Page 38


leading damage to health and life as well as

assets especially in downstream area. The main

impacts include: high risk of broken of dam in

the downstream hydropower plants, flooding

cause for downstream communities, block

transport routes, negative impacts on activities

and incomes of downstream communities, high

No. Social issues Information

PREPARATION AND CONSTRUCTION PHASES

1 Impacts to communities There are 09 relocated households (36 people).

The most local people there are Tay and Nung

ethnic minorities who still keep their

backward customs thus, the project may

impacts their daily life. However, this disorder

only affects within construction time of

project.

The transportation of materials and equipments

does not affect much to the local people.

Most of local people expect that development

of project will faciliate to improve their

production and living standards.

2 Labor influx due to

construction workers and

conflict between workers

and communities

According to fesibility study, there are around

300 staffs/workers who are mobilized for

project construction at the project site in the

peak time.

Complementary areas are located at both sides

of the river, but mostly on the left side of the

dam. At the upstream of the dam, there is a


Page 40


concrete mixing plant. The crushing plant is

located at the stone quarry, 7 km away from

the site along the national road 43.

The relationship between the investor and

local people who are living in affected area is

quite good. The investor has experience in

management of workers and security in the

local area when building the former projects.

The security of Ly Bon and Vinh Quang

communes, Bao Lam District and Bao Toan

commune in Bao Lac District is quite good.

The social evils such as drugs, theft and fight

are seldom therefore conflicts between

workers and local people will be low.

The results from site survey show that there is

an primary school located about 500m away

from left hand site of the dam which will be

not seriously impacted by project. There are

also 2 schools (secondary and highschool)

which located on other site of Nho Que river,

thus the project will create impacts on the

access road to schools of the pupils since the

iron bridge will be removed, therefore, the

replacement access road need to be provided

to ensure all pupil will be safety on the way to

schools.

3 Increase income sources for

the local people

At the beggining of construction phase,

project will gather large amount of

staffs/workers thus, 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

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 …


Page 41


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.

4. MITIGATION MEASURES FOR NEGATIVE IMPACTS

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

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

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

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

developer/contractors/subcontractors who must comply with mitigation measures are

presented in Table 4.1.

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

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

contractors. Power Construction Joint Stock Company No. 1 has responsible to

integrate the EMP into the detail design and bidding contracts. Power Construction

JSC No. 1 assigned one staff who is in charged in environmental management for Bao

Lam 1 Hydropower plant. This 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 Power

Construction Joint Stock Company No. 1, BIDV Hanoi; (iv) Participating courses on

environmental management which are held by GdoE PMB and WB.

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

minimize environmental impacts mentioned in EMP then monitoring construction

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

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

performed adequate measures to minimize environmental effects. The contractor will

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

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

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

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

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

make provisions for compliance and sanctions for environmental violations in the

contract with the contractor.

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

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

cost to repair the violation.

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

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

project to the investors will happen

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

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

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

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

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

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

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

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

9. PUBLIC CONSULTATION AND DISCLOSURE

9.1. Public consultation

In the preparation phase, Power Construction No.1 JSC carried out the following tasks:

1 The feasibility study report and investment report of Bao Lam project were

submitted to the People Committees of Ly Bon, Vinh Quang and Bao Toan Commune.

Based on the comments from above local authorities on locations of the main

components, the investor can revise promptly project documents to get effective

investment and mitigate compensation of relocation and impacts on environment and

communities.

2 Social survey by interview directly representatives of local authorities and

affected households was done by investor. Results from these investigations show that

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

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

internal roads.

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

were done.

4 Preparing EMP report.

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

offices of Peope Committes of affected communes Ly Bon, Vinh Quang and Bao Toan

from 08-11 July, 2014. Participants consist of representatives from Power

Construction No.1 JSC, local authorities of communes of Ly Bon, Vinh Quang, Bao

Toan, environmental and social consultants, affected households (Minute of meetings

and list of participants are presented in the Annex 3). The main content of consultation

meetings as below:

Investor presented the main information of project:

Bao Lam 1 hydropower project has with the capacity of 30 MW is categorized

of impoundment, regulated by reservoir, annual electricity production of 115.7

x 106 kWh. The headwork consists of gravity concrete dam with n x b x h = 6 x

15 x 13.5m, spillway with BxH = 15 x 13.5m. Volume of reservoir is 8.9x106

m3. Designed flow: 365 m

3/s; minimum flow 37.1 m

3/s. Bao Lam 1 hydropower

project is under small hydropower master plan that was approved by Cao Bang

Provincial People Committee.

Construction of Bao Lam No.1 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 commites to compling to mitigation measures so

that the negative impacts could limit. Investor also develops CDM for Bao Lam

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

residents for project.


Page 90

Environmental consultant presented generally the environmental negative/positive

impacts and mitigation measures which will be applied by investor/contractors during

project implementation as below:

Positive impacts:

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

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

sectors in the locality.

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

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

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

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

allow to develop 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

115.7 million kWh. Project also applied CDM and as estimated the certification

emission reduction is received around 80,000 ton of CO2 per year.

Negative impacts:

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

components such as dam, powerhouse, swichtyard, transmission line etc that cause

some unavoidable impacts as below:

103.91 ha land will be appropriated permanently for buiding components of

headwork and some more land will be acquired temporary for supported

facilities.

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

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

landslide/erosion at these sites.

Process of blocking river, constructing dam bringing about increasing turbidity

and reduction of water quality of Gam and Nho Que rivers.

Activities such as blasting, excavation of foundation, quarry, levelling soil and

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

constructed machines, construction etc will impact to environment causing air

pollution in case the mitigation measures are not applies.

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

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

disturb to local residents.

Constructed and domestic solid waste that discharged from workers will cause

pollution of air and water river if it is not well controlled.


Page 91

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.

Storage of water in the reservoir as well as operation of Bao Lam 1 hydropower

plant will cause changing of Gam and Nho Que river flows regime from behind

dam to downstream of powerhouse. In the project site, rive flow regime will

replace by reservoir hydrography regime that performs by fluctuation of water

level. In the operation phase, the reservoir has negative impacts to aquatic

species and fishs which have habit of emigration. This affect is unavoidable

when construction and operation of hydropower projects.

Some key main mitigation measures:

Environmental consultant presented briefly draft EMP which will be complied by

investor 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, cultivative and public transportation

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

limited by contractors.

The contractors are responsible for informing 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 least 100m, do not

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

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

To establise the worker regulation 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 levelling 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.

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

Questions and answers are summarized as below:

Ly Bon commune, Bao Lam district:


Page 92

Questions from representatives of local authorities and affected households

Chairman and vice chairman of People Committee represent Ly Bon commune

is one of the New Rural Planning Region’s affairs of province, due to Bao Lam

1 Hydropower Project construction activities of New Rural Planning Region

temporarily stop and affect to the local people’ life. Beside that, representatives

of local authority request investor to provide related documents of designs and

compensation to affected households. They suggest investor should has

harmonized compensation level and support stable livelihood for affected

households.

Vice chairman of Commune People Committee raised an issue of constructed

company taking advantage of the hydropower project construction to mining

lake (sand, gravel) which cause erosion and depletion of natural resources.

Beside that, there are some companies ask permission of sand mining on Gam

riverbed but the primary purpose of gold mining, therefore investor is required

to recommend to Department of Natural Resources and Environmen of Cao

Bang Province not to permit them to exploit.

Almost affected households consent to Bao Lam 1 hydropower project

construction but some of them wonder about compensation such as land areas

and price of compensation.

Answers of developers and environmental consultants

Compensation will resolve in the other working days with Resettlement

Committee and local authorities. Investor will provide documents relating to

compensation to coummne authorities. The method to culculate acquired land

as well as compensative expenses will be based on the current regulations

setting by the government and annual updated regulation of Cao Bang province.

Measures of livelihood stability for affected households will be considered by

investor.

Vinh Quang commune, Bao Lam district:

Questions from representatives from local authority and affected households

Chairman of communal people committee supports to Bao Lam 1 hydropower

project construction however he requires investor to deal with complaints from

affected persons on compensative procedures and expenses, count of property

on land.

Affected people complained on compensative land and expenses, livelihood

after acquired land for reservoir. They are worry about their livelihood after

powerplant is put into operation.

Some of affected residents raised issue of widening their land last year with

high price (because of buying and renting machine for grading) whether

investor compenses satisfactory in expenses as well as procedures.

Answers from investor and consultant:


Page 93

Compensation of land areas, expenses as well as procedures will be done by

current regulations. Investor will coordinate to local authority to harmonize the

compensative requirements from affected households.

Regarding to supporting livelihood and providing new jobs for affected

residents, investor will try to deal with at the best effort.

Bao Toan commune, Bao Lac district

Questions from representatives from communal people committee and affected

households:

Vice chairman of Bao Toan Commune People Committee support to

construction project. Bao Toan commune the affected one at least, however, it

is difficult for households lose their cultivate land to get new cultivate land

(because of almost cultivate land belong to owner). Construction will also affect

to vegetation, however, within 2 years in constructing, it will be recovered

afterward.

Cultivative land in the commune is reclaimation of residents from surrounding

areas so vice chairman requestsInvestorcoordinate to local authorities

supporting them on land ownership during compensative implementation.

Investor is required to issue worthy compensation and to support livehood for
