I. INTRODUCTION
The subproject “Bac Ninh 3 220kV substation and connection line” is one of the subproject
identified for the second phase implementation under the World Bank financed Transmission
Efficiency Project (TEP). The subproject will be implemented in Yen Phong district of Bac
Ninh province and Soc Son district of Ha Noi City. The implementation of the subproject is
in line with the national Power Development Master Plan 7 (PDMP7). This implementation is
to receive and transmit capacity of 220kV voltage from national power system, to distribute
capacity to 110/22kV substation in region and to meet load demands, strengthen reliability
and supply energy for industrial zones of Yen Phong 1, Yen Phong 2, urban and residential
zones, in Yen Phong district, other regions in Bac Ninh province and surrounding regions.
Activities of the subproject are to (i) construct a 220/110/22kV substation with capacity of
three transformer units of 220/110kV-250MVA and two transformer units of 110/22kV –
63MVA; (ii) construct a double-circuit 220kV connection line with 4,723m in length from
connection tower of Hiep Hoa – Dong Anh – Bac Ninh 2 500/220kV transmission line to
220kV switchyard of Bac Ninh 3 220/110kV substation. These activities could cause
negative impacts to environment and local communities during the period of pre-
construction, construction and operation.
To ensure the potential negative impacts are identified and mitigated during the
implementation period of the subproject and to comply with the Bank’s Policy on
Environmental Assessment, an Environmental Management Plan (EMP) of the subproject has
been prepared in compliance with the Environmental and Social Management Framework
(ESMF) of the TEP and in connection with the subproject EIA. This EMP is an instrument
that details: a) all anticipated adverse and social environmental impacts; b) the mitigation
measures to be taken during the implementation and operation of a the subproject to eliminate
or offset adverse environmental impacts, or to reduce them to acceptable levels; c)
monitoring objectives and type of monitoring with linkages to the impacts assessed in the
EIA report and the mitigation measures described in the EMP; d) the actions needed
including institutional arrangements to implement these measures; e) capacity development
and training to support timely and effective implementation of environmental project
components and mitigation measures; and f) implementation schedule and cost estimates for
implementing the EMP. The mitigation measures proposed in the EMP shall be integrated
into the bidding and contractual documents, and monitored and supervised during all the
phases of subproject implementation and operation.
According to Vietnam’s environmental assessment regulation, the subproject is subject to
prepare an EIA for submission to the Ministry of Natural Resources and Environment
(MONRE) for appraisal and approval. The report on EIA was submitted to MONRE in
February 2014 and was approved by MONRE under the Decision No.919/QD-BTNMT on
05th May 2014.

2.2. WB’s Safeguard Policy
The environmental and social screening according to the criteria described in the Bank’s
policy on environmental assessment has been carried out, and the result shows that the WB
policies on Environmental Assessment (OP 4.01), Physical Cultural Resources (OP 4.11),
and Involuntary Resettlement (OP/BP 4.12) are triggered for this subproject. The subproject
has also to comply with the WB’s requirements on public consultation and Policy on Access
to Information. The implementation of the policy on Involuntary Resettlement (OP/BP 4.12)
is addressed in the Resettlement Policy Framework (RPF) of the TEP project and the
Resettlement Plan (RP) of this subproject.
Environmental Assessment (OP/BP 4.01):
Environmental Assessment (EA) is an umbrella policy for the Bank’s safeguard policies. The
overarching objective is to ensure that Bank-financed projects are environmentally sound and
sustainable, and that decision-making is improved through appropriate analysis of actions and
of their likely environmental impacts. The EA process is intended to identify, avoid and
mitigate potential impacts of Bank operations. EA takes into account the natural environment
(air, water, and land); human health and safety; social aspects (involuntary resettlement,
indigenous peoples, and physical cultural resources); and transboundary and global
environmental aspects. EA considers natural and social aspects in an integrated way.
This subproject triggers OP 4.01 because it involves the installation and operation of a high-
voltage substation, requiring the identification, mitigation and monitoring of potential adverse
environmental and social impacts. As required by OP 4.01 and the government EA
regulation, the subproject has prepared an EIA and an EMP that meet the Government’s and
the World Bank’s safeguards requirements. By the TEP appraisal, the subproject EIA and
EMP have been disclosed locally at the subproject sites as required by OP 4.01 and the
Bank’s policy on access to information.
Involuntary Resettlement (OP/BP 4.12)
Bac Ninh 3 220kV substation and connection line
Environmental Management Plan
Page 7
The Involuntary Resettlement policy seeks to prevent severe long-term hardship,
impoverishment, and environmental damage to the affected peoples during involuntary
resettlement. OP 4.12 applies whether or not affected persons must move to another location.
The Bank describes all these processes and outcomes as “involuntary resettlement,” or simply
resettlement, even when people are not forced to move. Resettlement is involuntary when the
government has the right to expropriate land or other assets and when affected people do not
have the option to retain the livelihood situation that they have.
This policy is triggered because the subproject would have impacts involving the temporary
and permanent involuntary taking of land and the loss of structures and assets associated with
the land for the power towers and the right-of-way of the transmission line. By appraisal, the
subproject has prepared and disclosed a RP locally at the subproject sites and at the Bank’s
InfoShop. The RP includes the measures to ensure that displaced people are: (i) informed
about the options regarding resettlement; (ii) consulted and offered alternative resettlement
choices; and (iii) provided with effective compensation and livelihood restoration. The final
subproject final RP will be disclosed locally at the subproject sites, at the Bank’s InfoShop,
and the Vietnam Development Information Center.
Physical Cultural Resources (OP/BP 4.11):
Physical Cultural Resources Policy (PCR) is intended to ensure that projects identify and
inventory cultural resources that are potentially affected by the project. PCRs include
resources of archaeological, paleontological, historical, architectural, religious, aesthetic or
other cultural significance. Projects should include mitigation measures when there are
adverse impacts on physical cultural resources. Appropriate agencies, NGOs and universities
should be consulted.
OP 4.11 will be applied to this sub-project because the subproject would involve the
relocation of seven (07) graves at proposed substation’s location. Mitigation measures will be
addressed in the respective subproject’s RP. For this subproject, it is required that all
construction activities will include mechanisms to address chance finds to avoid or mitigate
adverse impacts on PCRs. Chance finds procedures have been prepared and included in
environmental management plan of the subproject. These chance finds procedures shall form
part of the safeguard procedures in the Technical specifications for Contractors.
World Bank Group Environmental, Health, and Safety Guidelines
World Bank-financed projects should also take into account the World Bank Group
Environmental, Health, and Safety Guidelines1 (known as the "EHS Guidelines"). The EHS
Guidelines are technical reference documents with general and industry-specific examples of
Good International Industry Practice.
The EHS Guidelines contain the performance levels and measures that are normally
acceptable to the World Bank Group and are generally considered to be achievable in new
facilities at reasonable costs by existing technology. The environmental assessment process
may recommend alternative (higher or lower) levels or measures, which, if acceptable to the
World Bank, become project- or site-specific requirements.
This subproject should conform the Environmental, Health, and Safety Guidelines for
Electric Power Transmission and Distribution and the General EHS Guidelines.

district, Ha Noi city. The connection line of the subproject will start at Bac Ninh 2 220kV
substation in Cho town (center of Yen Phong district), run parallel with highway No.18 , and
ends at connection point in Kim Lu commune (in the Southeast of Soc Son district). This
location is the gateway to the east of Ha Noi city and highway No.18.
This is of great advantage to traffic and foreign affair in order to develop rapidly
socioeconomic.
4.2. Climate, Topography, Pedology
a. Climate
Location of the subproject has a general characteristic of monsoon tropical climate,
specifically the Red River Delta region. Average temperature is 30°C - 36°C and 15°C - 20°C
Bac Ninh 3 220kV substation and connection line
Environmental Management Plan
Page 22
in the summer and winter, respectively. Cold season is from October to March of the
following year. The weather is affected by the Northeast monsoon, which usually brings
frosts and hoarfrost. Dry season is from April to October, and itis affected by the Southeast
weather, which usually brings rains. Rain depends to the season. Annual rainfall is about
1,600 mm peryear. Rainyfall during the rainy season is accounted for 80% of the annual
rainfall. Average air humidity is 83% per year. Sunny hour is 1,700 hour per year, which is
favourable for rice crops, industrial trees, and other trees.
b. Topography
The subproject is located in the riverside plain region to the South of Soc Son district and the
plain region of Yen Phong district. The elevation of the proposed substation location is from
3.9m to 4.5m and the elevation of the connection line in the field region is from 4.2 m to 7.0
m.
c. Pedology
The subproject location at Cho town, communes of Yen Phu, Hoa Tien and Soc Son is
riverside plain region. This region has consolidated alluvium of Cau river and Ca Lo river;
thus, the soil is rich and available for the cultivation of agriculture, farm products, and
industrial trees within a short period (such as rice and crops).
4.3. Situation of Technical Infrastructure
a) Traffic
Location of the subproject is the gateway to the east of Ha Noi city so the traffic
infrastructure system is relatively developed. Highway No.18, Noi Bai international airport
and Cai Lan port (in Quang Ninh) will run parallel with the subproject’s location; this route
will be 150m from the substation to the north and run parallel with the connection line and
will be 50 to 91m from the subproject’s location. In addition, a complete traffic system
connected between the cities, provinces and economic region (in districts of Yen Phong and
Soc Son). Road system connected between highway No.3 in Ha Noi and Thai Nguyen,
highway No.18 and connection line route in Yen Phu commune. Provincial road No.295 to
the north connected with highway No.18 at Cho town and highway No.1A to the south
upgraded. Provincial road No. 286 to Bac Ninh province and Ha Noi was connected with
highway No.3. Therefore, traffic condition is relatively advantage.
b) Hydraulic Work
Water sources used for agricultural cultivation at the subproject’s location are taken from Cau
river and Ca Lo river via irrigation and interior canals system. At location of the subproject
has about 630m in length of irrigation canal. Section of this canal will be filled during
leveling the substation so this canal will be restored around the substation’s fence in order to
supply and drain water for paddy fields surrounding the subproject’s location.
c) Domestic Water Sources
People use currently local water system and well water to provide daily needs in Cho town
and communes of Yen Phu, Hoa Tien and Kim Lu, respectively. Water for fire-fighting and
daily needs of operators will use local water system in operation phase.
d) Power Supply
Currently, 100% of households in subproject’s location have been used power source from
the national power grid of the existing 220kV transmission line along highway No.18 via
22/0.4kV transformer installed on poles. Construction phase, the subproject will use the
Bac Ninh 3 220kV substation and connection line

Page 23
current local power grid. In addition, the subproject will propose to construct a 22kV shunt
line (about 200m long) from the existing 22kV transmission line along highway No.18 to
substation and install a 22/0.4kV transformer on pole with nominated capacity of 3x25kVA
in order to provide power in construction phase and testing equipment.
4.4. Land Use and Buildings on Land
a) Land Use
Total area of the subproject’s ROW is 103,906 m2, in which construction area of 19 tower

4.5.2. Water Environment Quality
a) Surface Water Quality
Surface water sampling at interior canals of the subproject location shows there are signs of
pollution and microbial contamination. This also shows that some specific surface water in
the agricultural region will be highly impacted by the amount of fertilizer which will pollute
the high nutrient content in water. Other pollution criteria such as pH, suspension of solid
substance, oil, and etc. have met the permissible limits of the QCVN 08:2008/BTNMT –
National technical regulation on surface water quality.
b) Quality of Underground Water
According to the result, the quality of the underground water at certain wells of households in
the subproject’s location is fairly good. Thus, the permissible limits of pollution criteria are
met according to QCVN 09:2008/BTNMT – National technical regulation on underground
water quality. However, due to the effect of geology in local region, iron contents in
underground water at the sampling locations have exceeded lightly in comparison with the
stipulation from 1.09 to 1.23.

c) Culture and Society
Issues around the culture and society within the subproject’s location is the local authority’s
main concern. The subproject will contribute directly and indirectly into the improvement of
living standard for the local people, such as supplying power for production, development of
econimics, the lighting of all public works, and etc.
The subproject is not in area of historical area, cultural heritage site, social-culture structure,
nor national defense.
V. POTENTIAL IMPACTS
The screening of the environment around the subproject areas indicate that it is eligible for
financing with an exception that the subproject will not involve possible high risk and will
not create potential adverse impacts on: (a) critical natural habitats and/or protected area
including proposed protected areas; (b) loss or damage to cultural property, including sites
having archeological (prehistoric), paleontological, historical, religious, cultural, and unique
natural values; (c) water regime, particularly water flow; and (d) other significant
environmental and social impacts.
The subproject will bring about positive changes to the local and regional economies and
creating favorable conditions for local production activities and other social benefits.
The implementation of the subproject would mainly cause land acquisition, increased dust
generation, air pollution, domestic waste, and health and safety issues due to construction
activites and electrical magnetic field. However, these impacts are not significant, temporary,
and localized with available mitigation measures. So the subproject has been categorized as a
Category B project according to Policies of OP 4.01 and satisfied to use the World Bank’s
loan.
The potential negative impacts of the subproject are identified in Table 5.1. These can be
minimized by applying the proposed mitigation measures which has been developed for the
subproject in Table 6.1.

Pre-construction phase
1 Location of the
subproject
Small Short-term The subproject’s location is not near or in cultural heritage sites, nature reserves or buffer
zone of protected areas, wetlands, estuaries, nor forests. However, the subproject’s location
will affect the land and cultivation activities of 63 households, whose land will be
permanently acquired by the subproject. In addition, Ca Lo river, lake, and Highway No.18
will cross the connection line. Impacts at the intersection will take place during the pre-
construction and construction stages. These impacts will be minimized during the
implementation.
2 Permanent land
acquisition and
affected land in the
ROW
Moderate Short-term
and long-
term
Area of permanent land acquisition is 52,941,6m2, in which construction area of substation
is 36,775.0 m2. Access road area is 11,416.0 m2. Tower foundation area is 4,750.6 m2. Area
of rice field is 42,637.6 m2; it accounts for 85% of total affected area. Area of crops land is
1,390 m2; it accounts for 2.6% of the total affected area. Irrigation canal land is 6.536,0 m2;
it accounts for 12.3%. Local road is 2,178.0 m2; it accounts for 4,1%; Area of grave land is
200.0 m2; it accounts for 0.4% of total affected area for construction of the project.
Residential land and house don’t exist in permanent land acquisition area of the subproject.
However, 63 houses will be permanently affected by the subproject. There are seven
graves with a land area of 200m2 located in the substation. These graves had existed for a
long time and they will be moved to another place.
In addition, the overhead connection line also affects the use of land in the ROW with area
of 99,155 m2. Most of areas affected by the ROW is rice land. Rice fields do not violate
the safety distance from the conductors to land surface; thus, the local people can cultivate
in the ROW without any impacts. There are four houses in the ROW with metal roofs.
These houses will continue to exist in the ROW when they comply with a roof-grounding
to ensure a safety for the project.
The land acquisition will affect 63 households, whose land is in the proposed substation
and the connection line. However, there are not anyhouseholds to be moved by this
acquisition. Additionally, according to the investigation and collection from rice activities

of impacts
Impact
duration Impact Description
of these households, the land acquisition only reduces one portion of total their income.
Most of them has obtained other income from non-agricultural activitives. Site clearance
will be implemented after the harvest season to reduce damages to crops.
In addition, according to the statistical report on socio-economic, the economical
mechanism at the subproject’s location is being grown in the industry as well as trade and
services. Many industrial zones are being established and attracted investors to Bac Ninh
province. Many works of the industrial field are being grown each year. Therefore, a heavy
burden of the local authority in finding a new job for workers who are impacted by the
acquisition will be minimized.
The cultivation land acquired will affect local people; however, these impacts can be
minimized through measures of compensation and assistance according to the stipulation of
the Government to ensure their life and security.
3 Temporary land
acquisition
Small Short-term The land acquisition will be temporarily acquired during the subproject’s implementation
such as storage of materials and equipment and stringing wire. This land will be recovered
after completing the subproject. This land locates in the ROW and it does not affect life of
the local people. Land acquisition area for construction of a connection line is summarized
as follows:
- Temporary land acquisition for tower foundation is 6,483.6 m2
- Warehouse, storage of equipment and materials is 970.9 m2
- Stringing wire: 800 m2
Construction and storage of equipment and materials will be implemented at the substation
so it is not necessary for expanding a temporary land area. Construction at each tower
foundation location only lasts from one to two months so the temporary acquisition for
construction only affects a crop.

4 Effects on vegetation
and habitat area due to
site clearance
Small Short-term Vegetation is mainly rice at the subproject’s location. Site clearance will be done after
harvest season so the vegetation is mainly rice stubble. Wheat plant is low and harvesting
period is short so they can stay in the ROW without being chopped down. Land clearance
only includes area of construction and temporary acquisition plan.
Generally, these clearance activities at the substation and connection line is assessed as a
minor impact and mitigable. The affected trees mainly get an economical value without
ecological one.
5 Effects on irrigation
canal and local road in
substation’s location
Moderate Short-term At proposed substation location has interior canals with 630m in length and 2-4.5m in width;
these canals is used for irrigation of the surrounding rice field and area of them is 6,536 m2.
Local road runs along with irrigation canal, which is used to access rice-field of local people.
Length of this local road is 630m and affected area by the subproject is 2,178 m2. These
canals and local roads will be filled prior to construction of the project so they will cause a
clogging of irrigation system and as well as a stopping of entrance to local road of people.
This affects the production of farmers around the proposed subproject location. Therefore,
these canals and local roads should be re-establised before leveling the substation’s site.
6 Risk on healthy and
environment due to
explosive and
chemnical substance
Small Short-term The subproject does not use chemical and explosive substances for clearance and leveling.
However, according to the opinion of the Bac Ninh province Military Command, the
subproject’s location can also remain unexploded ordnance underground, and they can
explode in case of having collision between them and construction equipment. This will
cause accident for workers and damage assests of local people. Therefore, the subproject
should prepare a removal plan for unexploded ordnances to ensure safety prior to
construction.
7 Impacts on historical
area and cultural
heritage site.
Moderate Short-term The subproject’s location is not near to or in historical area or cultural heritage site. However,
there are seven ground-graves in the proposed substation location. Relocation of graves can
cause effects on spiritual life of households, who owned them if the relocation does not do
properly with the local customs. But this is the ground-graves, which was existed for a long
time so they ensure time for reburing according to local customs.

8 Effects on air quality
due dust generation,
exhaust gas from
construction vehicles
and transportation
means
Moderate Short term Dust will generate during construction such as excavation, backfill and transportation. This
dust is mainly generated from ground and it is easy to accumulate in a short time. This
source will be generated temporarily during construction phase. The subproject locates in
the agricultural region so its impact is small.
Dust and exhaust gas are generated from activities of engines of transportation means and
machineries. These means are used the clean-fuel so pollution content of waste gas is not
high. Effects on the waste gas are not significant in the subproject region because
generated location is mainly in rural region.
At section G5A – G5C of the subproject crosses over the residential region of Hoa Tien
commune. This location will bear strictly air pollution, the remaining locations of
connection line cross over the agricultural region so the effects on air pollution is small.
9 Impacts from noise and
vibration
Small Short term Noise and vibration can be caused by transportation means and mechinaries. However,
construction activities are mainly carried out manually or semi-mechineries with a small
means so the intensity of noise is not high.
Most of the construction locations are located in the rural region, away from residiential
region. The region caused strictly noise is the foundation locations crossing over the
residential region in Hoa Tien commune; section G5A – G5B has the foundation near the
local house.
10 Increase water turbidity
due to run-off and
erosion
Moderate Short term Ground and sand sweep away by the surface water flow at construction location can cause
erosion and increase turbidity. Especially, the subproject will mainly be located on
agricultural land with many interior canals and connection line will traverse Ca Lo river
and it also intersects two times with the lake. However, it is assessed as a small impact
because towers of this connection line will be 50m and 30m away from river and lake
edges, respectively. Terrain of the subproject’s location is flat. The construction period is
short. The construction site will provide pits and trenches for water drainage surrounding
the tower foundations. Quantity of excavation will be stored and maintained in a short time

and they can reuse to fill foundation after completing concrete work, and it also uses for
filling slope work.
The subproject will not construct towers on river, lake and canal so impacts causes by
erosion, run-off are assessed as moderate.
11 Impacts on
environmental quality
due to water waste.
Moderate Short term Worker at the site is 80 persons in construction duration. Volume of domestic wastewater
will estimate 9.3m3/day. This volume would generate at tents of the substation and
connection line. However, these tents are far from canals and domestic wastewater only
generates in the construction period and rural region so impact on wastewater is not
significant. The wastewater is assessed as small and mitigable.
Apart from the domestic wastewater, during the construction period, the subproject also
generates construction wastewater, including pump pit drainage and a little capacity from
equipment and machinery’s sanitary during construction. This volume only happens in the
construction duration and component of the pollutant in waste water is mainly soil, sand,
non-hazardous substances. The soil and suspended-sand mixed in water will be easy to
deposit sediment in the temporary drainage trenches. Therefore, impacts on waste water are
as moderate.
12 Impacts on
environmental quality
due to waste.
Moderate Short term The amount of generated waste is 48kg/day for total 80 persons of the whole subproject in
construction duration. These amounts will be allocated at the two tents. Quantity of waste is
small; it does not contain hazardous components. This waste will be collected and handled
properly so it will not cause negative impacts on environment, unsanitary and effect on the
surrounding aesthetics.
Quantity of excavation will be reused for backfill work. Thus quantity of redundant soil is
small. These quantities will be fully utilized to slope banks against erosion in the tower
foundation of the connection line and do slope work at the substation. Redundant quantity
is small but if the contractor does not collect and store them properly; it will cause negative
impact on environment.
In the process of construction and installation of the subproject can generate a lot of
construction wastes such as concrete debris, formworks, steel scrap, crates, and etc.

duration Impact Description
However, most of these construction wastes can be recycled and reused so it would be easy
to control and collect this waste.
The waste substance will be collected and treated according to stipulations of solid waste
substance and the implementation schedule is short term (15 months). Thus, the generation
of solid waste substances is assesses as moderate and mitigable.
13 Water and soil due to
hazardous waste
Small Short term Hazardous waste is mainly oil and oil rags, which will be generated from activities of
maintenance of equipment, machineries and transportation means in the construction
process. The waste oil volume generates from 41 construction means will be estimated
about 287 liters/time, around 47.8 - 95.7 liters/month. This volume only happens at the
maintenance agents and they are collected by these agents. Therefore, this waste oil volume
is low at construction site; it only happens when having samll repairment at site. Waste oil
and oily rags can collect strictly, store and streat safely so these impacts are assessed as
small.
14 Soil erosion and
eboulement generation
caused by excavation,
leveling and fillback
duration
Moderate Short term Excavation, backfill, leveling and construction of the subproject will change structure of soil
surface, it will cause a soil erosion due to rain-water run off or wind. Specially, substation
base is filled higher than the natural ground level of 1.84m so if the contractor has not a
suitable measure for reinforcing the substation base, and then risk of landslide will happen
and can affect the surrounding rice-field. Construction of pole foundation can cause a
erosion of canal edge at location near canal and river. This will reduce the capacity of the
natural drainage in the regional location if it is not properly managed. Especially, the
connection line will traverse one time via Ca Lo river and twice via the lake.
However, the subproject’s terrain is flat and the construction its construction always meets
stipulations on safety distance at the location near to canal. The contractor will apply
reinforcement measures to protect soild erosion during the leveling and excavation of
foundation pit. The total quantity of excavated soil would utilize to slope and backfill
foundations and substation plan. In addition, river and interior canals in the subproject’s

region will be reinforced by the protection wall.
15 Impacts on road Moderate Short term Transportation, storage of equipment and materials at the site would affect local traffic and
installing tower and stringing wire at the cross section would interrupt traffic for a short
period of time only.
The substation would locate near Highway No.18, this location will be 150m from road
edge and the connection line will be 50-90m from road edge so transportation of equipment
and construction materials from Ha Noi city and local agents to the site is benefited by
Highway No.18. Therefore, transportation would not effect significantly to local traffic.
In addition, traffic activities will be affected by stringing wire work via road at intersection
section (Highway No.18 and Highway 3). However, the contractor will provide scaffold to
limit affects of local traffic during stringing wire.
Traffic affects can also happen at the rush hour during construction of tower foundations at
the residential region of Hoa Tien.
16 Impacts on waterway
traffic
None None Connection line will intersect one time with Ca Lo river, the width of this river is 48m; and
twice with the lake, its width is 63m and 67m. Activities of stringing wire at section via
river can interrupt waterway traffic from one to two hours. However, cross section at Ca Lo
river and the lake does not exist the waterway traffic. Therefore, the subproject will not
affect the waterway traffic.
Local people sometimes use small boat to fish in the Ca Lo river, but its activity does not
happen regularly in section of the subproject’s location because river fish currently is small.
During the stringing wire, these boats can be affected at section across the river. However,
period of influence is short so effects on boat in the river is assessed as a minor impact.

17 Effects on house near
to section of G5A –
G5B
Moderate Short-term There are four houses located at section of G5A – G5B in Yen Vy village, Hoa Tien
commune, Yen Phong district. Two of them is near to location of tower foundation; it is
tower location No.9A. Distance between them is at least 20m. They are the fourth grade
house, brick wall, tole-roof with height of 4 - 4.5m. People lived in these houses will be
affected by noise and dust from construction activities. Structure of house can be affected
by shock from piling activity and landslide from excavation work. However, this is a house
without upstairs (single house); its height is low so negative impacts from these activities is
small. Landslide during excavation can be minimized by techinical method in construction
duration; and then impacts on noise and dust can be also minimized.
18 Effects on local traffic
system quality
Small Short term The transportation of materials with the high frequency can affect the rural road system in
the local region. The substation is 150m from Highway No.18 and the subproject will
contruct an access road for transportation of materials during construction and use for
operation period. The tower foundations of the connection line is 50m - 90m from Highway
No.18 so materials will be transported by manual means to the site.
Highway No.18 is designed to bear a heavy load so the transportation of equipment and
machineries for the subproject will not affect significantly. Transportation activities would
be carried out by manual means from Highway No.18 to the site, therefore, the
transmission frequency mostly increase low on the paths with bad quality. The subproject’s
activities will rarely affect these paths.
Nowadays, government authorities and local people closely monitor traffic management at
the local region. The means a weight load exceeding the limit will not be permitted access
to the local roads. This is also an issue for the contractor who must meet and carefully
propose the transportation solution and avoid damaging the local roads system and edge of
rice field.
19 Effects on health and
safety from camps and
spread of infectious
diseases
Small Short term Total workers are 80 persons at the subproject’s site. Sanitary condition and safety at the
tents and the site can affect the worker’s health. However, these works will be paid
attention by the contractor and these workers will be managed and checked periodically on
health. Therefore, the disease transmission from the worker is assessed as small because

this transmission would be treated by prevention measures.
20 Conflict between
construction workers
and local people
Small Short term Conflict between workers and local people can happen due to difference of income, culture
and behavior.
Living period of worker at the site is short (maximum of 15 months). The estimated
workers at the site is 80 people, in which, it is proposed 30% of the total labor workforce
will be local residents. Most of the non-local workers are technical labors who have
extensive construction experience. Therefore, the conflict between non-local workers and
local people and community are expected to be minor.
21 Accident risks to
workers and
community
Moderate Short-term Accident risk can happen in construction duration if the contractor is not paid attention to
safety measures. Accident can happen due to foundation excavation, crane operation, tower
erection and stringing wire, and etc. Accident can also happen to the construction workers
or local people surrounding the subproject.
Particularly, workers do works at height and install equipment on overhead poles; the
posibility of accident is large when the contractor does not provide labor protection
measures appropriately. Effects on health due to accidents is high and death from these
accidents for victims is very high.
However, according to the current stipulations, labor safety measures will prevent and
solve accidents in the construction duration. Therefore, it will minimize accident risks.
22 Interruption of services Small Short-term During construction process of the substation and the connection line, it is necessary to de-
energize some regions so it willinterrupt some services using power network. However,
this de-energizing work only happens at the end construction period when this line is
connected to the power network. The estimated de-energizing time is from one to two
hours.

23 Effects on
environemental quality
due to domestic waste
of operators
Small Long term Operators estimates about 22 persons at the substation during operation, these people will be
divided into three shifts and five groups. The substation operation activities will be carried out
according to shift regime, the actual number of operators is 7 persons per shift in maximum.
Operator’s activites will be generated a little volume of the domestic waste water and solid waste.
The volume of domestic waste water of the operators is about 0.84 m3/day. The quantity of
domestic solid is about 4.2 kg/day. Waste water and solid waste of the operators will
generate with the small quantity so they will not affect to environment. Waste water will be
collected and properly treated by septic tank before discharging into sewerage source.
Domestic waste will be collected strictly and stored temporarily in bins at the site after that
they will be moved by sanitation agent in local region.
24 Effects on
environmental quality
due to hazardous waste
Small Long term Hazardous waste generates during operation period is mainly oil leakage of the transformer
and oily rags. Oil of the transformer is fixed the interior of its one or capacitor and used to
cool or hold a function as an insulator so oil the transformer will not generate into the
environment. However, the oil can leak in the operation, repairment and maintenance
processes of the transformer, or the oil leakage can also happen in the process of oil
change. In addition, maintenance and santitation processes of the transformer will also
generate oily rags and this quantity estimates about 0.5 – 1.5 kg/month.
Oil of the transformer is mineral component with a long existence, it will affect to the
environment in case of leakage. But the transformer does not ensurely contain any
hazardous components of PCBs. Oil of the transformer and oily rags can collect strictly and
safely store and they will be transferred to the relevant agents for treatment.
25 Impacts due to noise of
the transformer
Small Long term As the technical result of 220kV transformer, they are designed according to the
international standard (IEC standard), the noise is around ≤ 76 dBA at distance of 2 m, so it
meets permissive limit (85 dBA) on noise in productive region issued at Decision
No.3733/2002/QD-BYT.
In reference with the monitored data which is being operated at 220kV substations, the
noise is 70 dBA at distance of 6 m to the transformer location, it meets value as mentioned
in QCVN 26:2010/BTNMT – maximum limits on noise in the production region at 6 a.m to

26 Effects on health due
electromagnetic field
Small Long term The substation and connection line are designed according to electrical standards and met
stipulations on safety at Decree No. 14/2014/ND-CP. And then, the connection line is
designed with suspension height that will ensure maximum electric field intensity. The
electric field intensity should be less than 5kV/m in the ROW at the height of 1m above
ground level as stipulated in Clause 2, Article 7 of Decree No. 14/2014/NĐ-CP.
In reference the monitored value of electric field intensity at some locations of 220kV
substation which is being operated, it was shown that value of electric field intensity is
more than 5kV/m at the location of circuit-breaker and transformer. But there are not any
locations in the substation that its value is over 25kV/m – maximum permissive limit of the
electric field intensity in working environment as stipulated at Decision No.3733/2002/QD-
BYT of Ministry of Health. Therefore, the substation’s operators can access to working
locations in the substation when meeting time as stipulated at Clause 2, Article 7 of Decree
No.14/2014/NĐ-CP.
27 Effects on
telecommunity system
None None Communication system can be affected by the subproject, including communication line is
near the substation and radio communication centers. However, the impact is calculated
and considered according to the current stipulations when designing the subproject so this
impact is assessed as a minor. The phenomenon of corona on surface of wire was designed
according to IEC and TCVN standards to limit properly effects to radio and television
communication.
28 Risk on electric shock
to health of workers
and operators and local
people around the high
voltage
Moderate Short term Design of the subproject focus on safety measures. Network risk and accidents can happen
in operation phase if the workers do not comply to the safety rules or local people do not
meet the safety stipulation on power network.
29 Fire hazard and oil- Moderate Short term Oil overflow will not be significant since the transformer is operated in a normal condition.

overflow of the
transformer
The oil over-flow only occurs when the transformer meets risks such as fire, which the
transformer should be paid close attention to during the operation. Fire hazard can happen
in many different reasons. They can occur inside or outside of the transformer and can be
increase the risk to high.
However, the substation has designed a fire-fighting system for the transformer. If fire
occurs, the fire-fighting system will alert with signals and extinguish the fire automatically.
This will prevent the fire from spreading to the outside location of the transformer and
outside of the substation’s gate.. Therefore, transformer’s risk will not impact to the
surrounding of the substation. In addition, the substation also provides a pit to collect all
oily leakage volumes if any.
30 Hazard on collapsed
tower
Moderate Short term Towers of 220kV transmission line can be collapsed by lighting, wind, or storms. Weak
foundation, especially at towers in flooded location can cause the transmission line to
collapse as well. However, design and supervision have been implemented will and met
safety standards. Tower foundation is designed on the basic of topography conditions,
geology, and hydrometeorology of the region. Its design withstands against natural
elements as statistics has shown over the last 20 years.

Conclusion: The implementation of the subproject would mainly cause land acquisition, increased dust generation, air pollution. However, these impacts
are not significant, temporary, localized impacts with available mitigation measures. Therefore, the subproject is assessed as B environmental category in
accordance with the WB’s criterion and eligible for funding by Transmission Efficiency Project.
