I. INTRODUCTION

At present, power source supplying Can Gio district is Nha Be 220kV Substation

(2x250 MVA) and one diesel generator with the capacity of 400 kW supplies power to Thanh

An commune locating on one island (called Thanh An island commune).

The existing Nha Be – An Nghia – Can Gio 110kV single-circuit transmission line

(TL) directly supplies power to An Nghia and Can Gio 110kV substations. In the future, this

TL will supply power to Aquaculture Center 110kV SS (newly constructed) (1x40MVA) and

ensure to supply power to An Nghia and Can Gio 110kV substations that will be enhanced

their capacity to 2x16MVA/ SS.

Now, Nha Be - An Nghia - Can Gio 110kV TL hasn’t been closed loop, thus it does

not ensure to supply stably and reliably Can Gio district with power. In the other hand, the

existing TL’s some sections are still used AC120 conductor with the load capacity of

70MVA, thus it does not ensure power transmission for 110kV substations which will be

enhanced capacity and constructed newly in the region in the future (104MVA).

“Stabilization and reliability enhancement of power source for supplying Can Gio

district -HCMC” subproject is one of the subprojects, which will be implemented in stage I

of Vietnam Distribution Efficiency Project (DEP) of Vietnam Electricity (EVN) loaned by

the WB, and constructed in the area of Can Gio district - HCMC.

Activities of the subproject include:

(i) Upgrading (to keep tact the TL direction and its ROW, only change in tower

foundation location, conductor pulling and scatter) the existing single-circuit

110kV TL to the double circuit TL for the TL section from tower No. 32 (T32) to

tower No.53 (T53) with 4.06 km in length (hereafter called Section 1);

(ii) Taking down the existing single-circuit 110kV TL for the TL section from tower

No.32 (T32) to tower No.53 (T53);

(iii) Newly constructing a double-circuit 110kV TL section from tower No.53 (T53) of

the existing single-circuit 110kV TL to An Nghia SS with 9.915 km in length

(hereafter called Section 2);

(iv) Taking down the existing single-circuit Nha Be – An Nghia 110kV TL section from

the existing tower no.53 (T53) to the existing tower no.108 (T108) with 9.7km in

length.

These activities can cause negative impacts on environment and local communities in

the stages of pre-construction, construction and operation of the subproject.

To ensure that potential negative impacts are determined and mitigated during

subproject implementation process and conformed to the WB’s environmental assessment

policy (OP/BP 4.01), an environmental management plan (EMP) of the subproject has been

prepared in accordance with the guidance of the DEP’s Environmental Management Frame

(EMF). The EMP includes contents as description of the subproject, policy framework,

applied national technical regulations on environment, potential negative impacts, proposed

impacts mitigation measures which will be implemented in the stages of pre-construction,

construction and operation, and implementation organization and arrangement.

According to new Vietnamese regulations, the subproject must establish a report on

environmental impact assessment (EIA). Its EIA is being established to submit to the

Department of Natural Resources and Environment of HCMC for approval instead of the

previously approved Environmental Protection Commitment (This commitment was



established by the PO and approved by Can Gio DPC at Letter No. 409/XN-UBND-TNMT

V. POTENTIAL IMPACTS

Table 5.1: Potential impacts of the subproject (environmental screening)

Screening questions Yes No Screening description

1. Subproject's sitting:

Is the subproject site adjacent to or within any

of the following environmental sensitive

areas?

- Cultural heritage site No

- Protected areas such as National Parks, Nature

Reserves, Bio-conservation areas, bird yards,

mangrove forest etc.

No

- Wetlands No

- Forests Yes - Section 1: It will not affect forest.

- Section 2: According to Letter No. 176/BQL dated September 28th

, 2011 by

Can Gio Protective Forest Management Board and Minutes of the meeting

dated December 22nd

, 2011 between the representatives of Can Gio Protective

Forest Management Board and the representatives of PECC4, the TL crosses

through plot No.5a which belongs to Can Gio Protective Forest with 200m in

length. However, in real measurement process, this section’s length is only

133m, in which there is 100m under the ROW of the existing TL (from the

existing tower No. 108 to the ending point). The 33m-length remaining section

crosses over Ong Nghia river. Main trees include mangrove, date-palm,...

It should not design to put any tower foundation in the land of the existing

Can Gio protective forest to mitigate impacts on vegetation cover of Can Gio




Protective Forest (the 133m- length TL section crossing over the protective

forest has one tower foundation to be newly constructed on the old An Nghia

110kV SS ground.

It should design the height of conductor higher than the highest tree (not cut

down tree under the ROW).

During the process of the TL construction and conductor scatter and pulling

through the protective forest, it should not cut down tree under the ROW.

Erecting scaffolding to support conductor in accordance with Norms. The

height of the scaffolding need be conformed to stipulation for every project it

need overcome. The scaffolding will be firmly connected together to support

many conductors at the same time. It will be ensured to resist wind pressure,

vertical load and the other expected loads.

Therefore, the impacts on Can Gio Protective forest caused by the subproject

are assessed as small.

- Estuaries No

- Buffer zone of protected areas No

- Rivers and reservoirs

Yes - Don’t design tower in rivers, reservoirs.

- Section 1: The TL crosses over Rach La canal with the width of 155m once,

and Rach canal with the width of 50m once. Now, boats still travel in these

canal sections.

- Section 2: The TL crosses over Rach La canal with the width of 86 m once

and Ong Nghia river with the width of 105 m once. Now, boats still travel in

these canal sections.

The subproject will not much affect the traveling activities of boats. The




impacts are only temporary in the construction time (about one day).

- Canals, ditches and irrigation system Yes - There is no irrigation system in the subproject area.

- The subproject doesn’t design tower in rivers, reservoirs

- Canal/ditch system in the subproject area is relatively much, thus the TL

crosses over some small canals/ ditches (their width is from several meters to

several-ten meters). However, the TL won’t impact on this ditch/canal system,

because it is in the air, and its tower foundations are not adjacent to canals,

ditches.

- Agricultural land Yes - Section 1: acquiring 3,259m2 land for constructing tower foundation (20

tower foundations), in which there area 414 m2

paddy land, 585m2 other annual

tree land (nipa), 2,260m2 aquaculture land (shrimp farms).

- Section 2: acquiring 188 m2 paddy land and 327m

2 other annual tree land

(nipa) for tower foundation construction.

2. Potential environmental impacts

Will the subproject cause:

2.1. Pre-construction stage

Permanent land acquisition Yes Total permanently acquired land area for tower foundation construction is as

follows:

- Section 1: Total permanently acquired land area for tower foundation

construction is 3,259 m2 (20 tower foundations). In which, there are 414 m

2

rice land; 585m2

annual tree land (nipa); 2,260m2

aquaculture land (shrimp

farms). The area of the smallest tower foundation is 124.32m2. The area of the

largest tower foundation is 174.24m2.




- Section 2: Total permanently acquired land area for tower foundation

(52 tower foundations), In which, there are 188m2

rice

land; 327m2

annual tree land (nipa); 6,389m2

traffic land (green belt between

Rung Sac and Song Hanh roads).

Temporary land acquisition Yes - Section 1: Total land area under the ROW is 64,960m2. Besides, the

subproject will also acquire temporarily land without the ROW with the area of

1,037m2 for constructing the worker camps, stockpiles,…In which, there are

247.3m2

closed stockpile; 515.6m2

opened stockpile; and 274.1m2

construction

material storage yard.

- Section 2: Total land area under the ROW is 158,640m2. Besides, the

subproject will also acquire temporarily land without the ROW with the area of

1,064.73m2 for constructing the worker camps, stockpiles,…In which, there are

163.18m2

closed stockpile; 235.60m2

opened stockpile ; 665.95m2

construction

material storage yard.

The subproject construction will be implemented in 9 months (from December

2012- August 2013) therefore the impacts caused by temporary land

acquisition are insignificant. The subproject will return the ground after

completing construction, acceptance and hand-over.

Resettlement of households? If yes, how many

households?

No There are no resettled households

- Section 1: None of HHs has house/structure under the ROW.

- Section 2: From G1 - G3, there is 01 house, 03 auxiliary structures

(bathroom, toilet and animal husbandry stall) of 2 HHs under the ROW, they

are not compensated, but are allowed to keep under the ROW after their wall

and roofing are upgraded and grounded.

The TL section from G3 to the ending point, which runs in the green belt

between Rung Sac and Song Hanh roads, there are 01 house, 10 other




structures under the ROW. They were inventoried and compensated by the

Project Owner of Rung Sac road in 2004 and 2005

For HHs whose houses/structures are under the ROW but not dislocated out of

the ROW, the Project Owner will implement treatment measures as upgrading,

grounding (to prevent from electromagnetic field) these houses/structures.

Would the resettlement site is environmentally

and/or culturally sensitive

No There is no resettlement site

In the past, there was any accident incurred due

to Unexplored ordnance after the war (due to

landmines or explosive materials remaining

from the war)?

No No

2.2 Construction stage

Encroachment on historical/cultural areas No

Encroachment on critical ecosystem (e.g.

sensitive or protected areas, national park,

nature reserve etc....)

No - The subproject won’t construct tower foundation in forest land.

- The subproject won’t use tower made of wood.(wood tower)

Disfiguration of landscape and increase in waste

generation

Yes * It will cause the disfiguration landscape in permanently acquired land area,

particularly as follows:

- Section 1: The area of permanently acquired land for tower foundation

construction of the upgraded TL is 3,259 m2

(this area is for 20 tower

foundations). In which, there are 414 m2

paddy land; 585m2

other annual tree

land (nipa); 2,260m2

aquaculture land. The area of the smallest tower

foundation is 124.32m2. The area of the largest tower foundation is 174.24m

2.




- Section 2: Total area of acquired land for tower foundation construction is

6.904m2

(this area is for 52 tower foundations), including 188m2

paddy land;

327m2

other annual tree land (nipa) land; 6,389m2

traffic land (green belt

between the roads of Rung Sac and Song Hanh).

- Wastes will include redundant soil and rock in construction process;

rubbishes from workers’ activities; wastes generated by taking down and

salvaging the existing TL unless they are collected and treated rationally.

Removal of vegetation cover or cut down of

trees resulted from clearance along the ROW?

Yes * Number of trees affected by the subproject is as follows:

- Section 1

+ The area of the affected paddy field is 960 m2;

- Section 2:

+ The area of the affected paddy field is 1,744m2;

+ Number of nipa which will be cut down is 355 trees;

Change of surface water quality or water flows Yes - In the subproject area, the turbidity of surface water sources will be increased

due to the impacts of tower foundation excavation activities and water pumped

from foundation pit (if any) will run into the rivers/canals in the subproject area

as Tra canal, La canal and Ong Nghia river.

- Increase in water turbidity due to runoff

and erosion

Yes Tower foundation excavation and filling process will cause soil/rock to be

loosen (especially tower foundations are located in complex locations)

Therefore it will cause an increase in surface water source’s turbidity in rainy

season. This impact is only temporarily in construction stage. Specifically, the

TL crosses over the following large rivers/canals:

- Section 1: Tra canal with the width of 155m; Rach canal with the width of

50m;




- Section 2: Rach La canal with the width of 86m and Ong Nghia river with the

width of 105m.

However, topography of the subproject area is relatively flat, and height

difference of two river bank sides (slope of two river banks) is small, therefore

soil erosion will be low.

- Waste water from camping sites is

directly discharged to the surface water

resources or not?

Yes - Number of construction workers will be different at every construction time. Thus,

the volume of waste water generated at each construction time will be different.

- The subproject surrounding area, the road and waterway system is relatively high

developed, local people are living here thus, won’t build camps for worker, but hire

local people’s house for worker to stay. For this reason, they won’t stay together in a

place but stay dispersedly along the TL.

- Section 1: Total number of workers participating in the subproject construction

will be 167 people, thus total volume of wastewater generated will be 13.3m3/day;

this sewage won’t concentrate but distribute dispersedly at the residents’ houses

hired for workers.

- Section 2: Total number of construction workers will be 130 people, including 02

independent teams, each team has 65 people (with 60 direct people, 03 indirect

people and 02 managers). Waste water volume generated in one day will be about

10.4m3/day at the residents’ houses hired for workers.

Characteristic of the transmission line is to carry out construction for every tower

foundation. Construction workers will be divided into small groups, thus waste

water will not gather in a place but distribute dispersedly in every tower foundation.

At each tower foundation location, there are about 15-20 people, construction time

of each tower foundation is about 11 days/foundation. Hence, waste water volume

generated at each tower foundation location is about 1.2 – 1.6 m3

/day.foundation.

This volume of waste water is small.




- Construction waste water is directly

discharged to the surface water or not?

Yes Construction waste water is mainly generated from underground water of

foundation pits, water for concrete maintenance.

Increase in the dust level? Yes - Dust is generated by ground leveling of the auxiliary area (stockpiles,

workers camps…)

- Dust is generated by tower foundation excavation and filling.

- Dust is generated by materials and equipment transporting vehicles

Increase in noise and/or vibration? Yes - Dust is generated by ground leveling of the auxiliary area (stockpiles,

workers camps)

- Dust is generated by tower foundation excavation and filling.

- Dust is generated by materials and equipment transporting vehicles.

- Number of machines participating in the subproject construction is as

follows:

+ Section 1: Total time of tower foundation construction is short. Number of

machines and equipment used in construction is not many, including 01

concrete mixer with 150 – 250 liters; 02 needle vibrators; 01 plate vibrator

+ Section 2: Total time of the subproject construction will be 9 months.

Machines and equipment used in construction include 12 concrete mixers; 31

trucks transporting equipment and materials; 03 cranes; 05 bulldozers,

excavator; 20 needle vibrators; 12 plate vibrators; 12 welding machines; 12

steel benders; 4 diesel generators; 18 water pumps; 12 hydraulic wire

compressors. These machines and equipment won’t be operated at the same

time, but dispersedly at each stage, work item, construction area. Therefore,

noise won’t be concentrative but dispersedly on the whole TL.

The process of tower foundation excavation and filling, and ground leveling




will be performed mostly by manual method. The construction activities will

be carried out in the daytime, and the transportation of materials and equipment

to the subproject site will be performed by manual and mechanical method.

Therefore, the impacts caused by noise on people in the subproject area are

very small.

Is there any risk of disease dissemination from

construction workers to the local people (and vice

versa)?

Yes Through information collection, the subproject area has had mumps.

According to the collected information on Vietbao website, up to November

24th

, 2011, in the territory of Can Gio district, there had been 160 people had

mumps (including 151 pupils). Also in the same period, in the subproject area

in Binh Khanh commune there was 01 case of mump catch. Therefore,

concentration of workers in the subproject area will increase risks of spreading

disease to workers and community.

Is there any potential for conflict between

construction workers and local peoples (and

vice versa)?

Yes Concentration of workers will cause disturbance daily life of local people.

Construction workers are managed by the contractor and registered temporary

residence registration to the local authority. However, conflicts between

construction workers and local people may be happened due to objective

reasons.

Are explosive and hazardous chemicals used

within the subproject?

No

Will the subproject construction cause

disturbance to the transportation in the

subproject site?

Yes - Materials and equipment transportation for the subproject construction will

affect traffic activities in the area:

+ The subproject construction will be implemented in a short period.

According to the proposed construction schedule, the subproject will be

implemented within 6 months for the TL section 1; and 9 months for the TL

section 2 from the subproject preparation to the completion and acceptance.

+ Section 1: Minor impact: The subproject crosses over some roads.




Especially, it crosses over the large earth road once, Tran Quang Quon road

once, and Ha Quang Voc road once. The surface width of these roads is 5m

with sand foundation, gravel pavement, and low vehicle density. Number of

vehicles participating in material transportation activities of the subproject

won’t be many, therefore this impact is assessed insignificantly.

+ Section 2: Medium impact: The subproject will cross over the inter-village

and inter-commune roads 36 times. Of which, it crosses over the asphalted

roads with the width of 5–11m 09 times, the earth roads with the width of 3-

10m 27 times. On the earth roads, the density of vehicles isn’t high. Otherwise,

on the asphalted/concreted inter-village/inter-commune roads with the quality

of good road surface, the density of vehicles and people participating in

transport activity is high such as the road accessing to Binh Khanh high school,

Binh Phuoc high school.

Total number of material transportation vehicles for the subproject construction

is 37 pieces including 05 trucks for transporting steel towers; 8 trucks; 12

dumper trucks, 06 water + fuel tank trucks; 06 worker buses.

Thus, vehicles serving material transportation for the subproject construction

will cause disturbance the transportation in the area, however this impact will

occur only in a short period (in the construction process) and only in the time

of one tower foundation construction and the time of conductor pulling and

scatter in one tower span.

- Conductors pulling and scatter activity: In the process of conductor pulling

and scatter though roads, the subproject will affect traveling activity of local

people and vehicles. However, this process will be performed only in a short

period, and conductor pulling and scatter is implemented in the air. Therefore, it

won’t affect much transportation activity.

Will the subproject construction damage to the Yes According to the actual survey, topography in the subproject area is flat, low.

Roads in the area are mainly earth ones, of which few roads the TL crosses




existing local roads? over are asphalted ones/concreted ones. Almost roads have low vehicle and

people density. They easily become muddy in rainy season. This causes

difficulty in traveling of local people. On the other hand, the participation of

vehicles for the subproject construction will increase degradation, damage of

road’s pavement.

Will soil excavation during the subproject

construction cause soil erosion?

Yes - It can cause soil erosion due to tower foundation excavation: The impact will

be minor because the process of tower foundation excavation will be mainly by

manual method with tools such as hack, scoop, crowbar, etc and combined

with mechanical method.

- Section 1: Tower foundations of the subproject will be mainly located in

shrimp farms, thus before constructing embankment that will prevent from

water to pump water for tower foundation construction, carrying out careful

excavation to prevent from landslide, erosion; and checking the depth of

foundation pits as designed. Excavated soil volume will be 14,450.53m3, filled

soil volume will be 9,763.94m3. These tower foundation locations is located in

the hollow places therefore it won’t cause erosion.

+ For foundations in the embankments of shrimp farms, excavation can cause

erosion and landslide

+ The subproject area’s topography is mainly low and hollow, and some

foundations are in shrimp farms, thus erosion by excavation is insignificant,

- Section 2:

+ Volume of excavated soil is 29,550.94m3; volume of filled soil is

32,748.84m3.

+ The subproject area’s topography is mainly low and hollow, and some

foundations are in the green belt of Rung Sac road, therefore erosion caused by

excavation is very small.




Will the subproject need to open new access

roads?

No

Will the subproject need to open temporary

roads for construction

Yes - Section 1: The subproject will construct temporary roads (not cross through

residential areas, schools, hospitals) to transport equipment as well as materials

and prefabricated elements to each location.

Some tower foundations in this section are mainly located in shrimp farms, so

access road will use its embankments.

- Section 2: Do not construct temporary roads.

Will the subproject cause fragmentation of

habitat of flora and fauna?

Yes The impact is insignificant

- Section 1:

+ The TL’s length through shrimp farms is 3,575m;

+ The TL’s length through the nipa, paddy area is 150m.

+ The TL’s length through river, stream is 335m

Tower foundations located in shrimp farms will be constructed after harvesting.

It should is embanked and constructed quickly and completely for every

foundation.

- Section 2: The affected trees within the ROW are as follows:

+ The affected paddy area is 1,744m2;

+ Number of Nipas which will be cut down is 355 trees; (in the scope of tower

foundations)

- Cutting down trees within the ROW will cause some small species such as

bird, insect, etc to lose their habitat.

The activities of the subproject construction and the appearance of workers will




cause disturbances to the life of animal species (some animal species will leave

their habitat) in the area.

Will the subproject cause impact on air quality? Yes - Increasing dust, exhausted gases, etc … due to activities of vehicles and

equipment in the construction process (due to soil excavation and filling,

transporting materials).

- Dust will be generated by the activities of tower foundations and auxiliary

works excavation, filling and leveling.

- Dust, gases (SO2, NO2, CO, etc) will be emitted from vehicles that will be

used to transport materials and equipment for construction; and from machines

that are used in construction. In the materials transportation process on earth

road will increase dust in the air.

- Section 1: equipment and machines directly participated in the subproject

construction will include 01 concrete mixer with 150 – 250 liters; 02 needle

vibrators; 01 platform vibrator;

- Section 2: equipment and machines directly participated in the subproject

construction will not be concentrated. Therefore, gas emission will have a low

concentrated level, and construction period of tower foundation will be short

about 11 days/foundation. These impacts will be only temporary in

construction phase.

Will the subproject cause risk to safety and

health of workers and communities in

construction stage?

Yes - In the subproject construction process, accidents can happen for workers and

local people if safety regulations aren’t fully obeyed in construction. The

accidents can happen such as traffic accidents, accidents due to touch with

equipment and machines, and fall from high working places, etc.

- Accidents can happen inside or outside the subproject site (on the road used

to transport materials and equipment, etc).




2.3. Operation stage

Will the subproject cause risk to safety and

human health (electric and magnetic fields,

electric shock etc.)?

Yes The subproject can cause accidents that will affect people in the process of

construction and operation.

- Electric shocks and accidents will happen if safety measures aren’t fully

obeyed.

- Fire, explosion incidents can happen due to short circuit, lightning or

breaking conductors that cause danger to workers, people staying near the

accident positions, etc.

- The distance from any components of houses/structures to the nearest

conductor when it is in maximum sag status is not less than 4m. This distance

can be encroached in operation process and cause accidents for people who

encroach.

On behalf of the PMB, the CSC will conduct the following tasks:

- Conduct regular site inspections;

- Review the status of implementation of environmental protection measures against the

EMP and contract documents;

- Review the effectiveness of environmental mitigation measures and subproject

environmental performance;

- As needed, review the environmental acceptability of the construction methodology (both

temporary and permanent works), relevant design plans and submissions. Where necessary,

the CSC shall seek and recommend the least environmental impact alternative in

consultation with the designer, the Contractor(s), and HCMC Power Project Management

Board;

- Verifying the investigation results of any non-compliance of the environmental quality

performance and the effectiveness of corrective measures; and

- Providing regular feedback audit results to the contractor’s Chief Engineer according to the

procedures of non-compliance in the EMP;

- Instructing the Contractor(s) to take remedial actions within a specified timeframe, and

carry out additional monitoring, if required, according to the contractual requirements and
