2.2. World Bank Safeguard Policy
An environmental and social screening of the subproject was undertaken in line with the OP
4.01 and it showed that the World Bank’s policies on Environmental Assessment (OP/BP
4.01), and Involuntary Resettlement (OP/BP 4.12) will be triggered for the subproject. The
screening has also resulted in categorizing the subproject as a Category B project. In addition,
the Bank’s requirements on public consultation and information disclosure will need to be
followed.
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 construction and operation of a high-
voltage substation and connecting overhead transmission lines, 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 draft EIA and EMP were disclosed locally at the subproject sites and
the Bank’s InfoShop in Washington DC on January 24, 2014 as required by OP 4.01 and the
Bank’s policy on access to information. The final EIA and EMP were disclosed locally at the
subproject sites, at the Bank’s InfoShop, and that the Vietnam Development Information
Center on January 24, 2014.
Involuntary Resettlement (OP/BP 4.12)
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 it 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 construction of the substation and the associated connecting line. By
appraisal, the subproject has prepared and disclosed a draft RP locally at the subproject sites
and the Bank’s InfoShop in Washington DC on January 24, 2014. 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 EIA and EMP were
disclosed locally at the subproject sites, at the Bank’s InfoShop, and that the Vietnam
Development Information Center on January 24, 2014.

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.

Rainstorm: During the hot season (from August to October), there are a certain number of
tropical depressions and typhoons forming offshore Philippines going through the East China
Sea then landing on the Northern Plain towards the West cause of heavy rains and strong
winds.
Hydrology
The 2 rivers flowing through the district are Day river and Tich river. The hydrological
mode of the district depends on Red River, Day river and Tich river and many other ponds
and lakes.
- Underground water: Underground water level stabilized at a depth of 0.0-1.2 m. Water
penetration is weak (Ia) according to TCVN 3994-85
- Surface water: the planned site building the substation is located on alluvial plains right
bank of Day river, there are many ponds and lakes. During the time of landform surveying,
the major substation area were flooded. Water supply to Day river and ponds, lakes, rice
fields is mainly the upstream water, rain water and irrigation water inland.. The level river
water usually high on rainy season. The water penetration is weak at the substation area
according to TCVN 3994-85.
- Surveying work about water supply for the substation: the planned site building the
substation is about 400m away from the residental area of Yen Noi village, Dong Quang
commune, Quoc Oai district, Hanoi city. Currently, local people use water taking from public
deep wells. Water purchase contract could serve the needs of water at the substation in Dong
Quang commune.
On the basis of the statistics data for 10 years (2002-2011) of the substation the water level
of Day river in the flood season (VI-X) is quite high. Monthly avarage water level for many
years in the flood months are greater than 110cm. The highest average water level is reached
211cm in August. Annual average water level at the project area is 105cm.
4.4. Land use
Xã Đồng Quang có diện tích tự nhiên 1.080,89ha, trong đó có 601,39ha đất nông nghiệp và
nuôi trồng thủy sản. Bên cạnh đó, đất phi nông nghiệp của xã chiếm 26,9% bao gồm 92,1ha
đất ở; 108,88ha đất giành cho giao thông; 85,09ha đất thủy lợi và 2070m2 phục vụ vệ sinh
môi trường.
4.5. Environmental baseline data
4.5.1. Air
Dust density
Suspended dust is one of the important criteria in the inspection evaluating impact of the
production areas on the environment. According QCVN 05:2009/ BTNMT, dust density of 300
μg/m3 in ambient air is allowed. Under this regulation, at all supervisory positions in the
construction area of 500 kV and 220 kV Tay Ha Noi substation (expected) the dust density are
very low and within the permitted value. Dust content in the same place in the afternoon is more
than that of the morning due to cool weather, high air humidity and light winds cause lower dust
content
The density of toxic gases
SO2 emission: According to QCVN 05:2009/ BTNMT, the density of SO2 in the ambient air of
300 μg/m3 is allowed in the project area, the gas density at all monitoring points are very low and
within permissible standards, from 51 to 68 μg/m3, the highest is at K5 position - on the dam of
Day River in the afternoon, influenced by traffic activities because there are many vehicles
involved.
220kV Tay Ha Noi Substation

Environmental Management Plan
23
NO2 emission: According to QCVN 05:2009/BTNMT, the NO2 density in the atmosphere is
allowed around 200 μg/m3. The analysis results showed that the density of NO2 in the surveying
area is much smaller than the allowable value. NOx density ranges from 42 to 54 μg/m3. The
small density of exhausted gases is small due to mainly agricultural activities in the surveying
area.
CO emission: According to QCVN 05:2009/BTNMT, the CO density in the air allowed is around
30,000 μg/m3, generally carbon oxide emissions in the project area and in the surrounding area
are permitted. The density of carbon oxide in the areas ranges from 1.745 to 1.905 mg/m3
Noise
Monitoring results showed that noise level Leq in most of the measuring positions is lower than
the allowed value in QCVN 26:2010/BTNMT. Noise levels in the measuring points on roads are
higher than that in the substation area, measured noise levels in the afternoon is higher than in the
morning, noon and night due to many life activities of local people at this time.
Vibration
Vibration unit is vibration acceleration (m/s2). Measuring results showed that the vibration
levels at most of points of the project area have the same value of zero (not detected).
4.5.2. Water condition
Quality of surface water environment
The analysis results indicated that the quality of irrigation water used for irrigation purposes for
farming (NM1) has most of the parameters following QCVN 08:2008/BTNMT applied to the
column B1 (used for irrigation purposes) but at a higher threshold. Some of nutrition figures as
NH4, NO3-, PO43- or nutrition figures such as TSS, BOD5 began exceeding permissible
standards, demonstrated the quality of this irrigation water has been contaminated at the low level
except for the heavy metal figures.
The water quality of Day River has most of parameters met the standard QCVN 08:2008/BTNMT
applied to the column B1 (used for irrigation purposes).
Quality of underground water environment
Generally underground water quality in the project area is permitted according to QCVN
09:2008/BTNMT. Some figures such as COD, ammonia, heavy metals (Asen, lead, iron)
approximate allowable values, especially the figure Coliform of underground water samples NN1
has the concentration of 3 MPN/100 ml, reaching a the highest threshold as QCVN
09:2008/BTNMT. Therefore, in case exploiting groundwater project for domestic purposes
should consider to that two parameters.
4.5.3. Soil condition
Content of metal Asen, Cd, Zn, Cu, Pb, Hg in soil, indicates the accumulation of heavy metals in
agricultural land. The analytical results of the heavy metal content for all examined samples are
much smaller as the standard QCVN 03:2008/BTNMT. This showed the soil samples of the
surveyed area are not contaminated heavy metals and relatively safe for the development of
production, the cultivation of food crops, vegetable.
Electro-magnetic condition
Survey results at measurement points are within the range of 1 kV/m, in the permitted value (eight
hours continuously), that less than value 5kV/m as specified.
For the strength of the magnetic field, the measured values are very smaller in comparison with
the standard and the magnetic sources in the area are almost undetectable.
4.6. Socio-economic status of the project area
Dong Quang commune has 3,330 households with the population of 13,759, including 7,880
persons at the working age, accounting for 57.59% of the population. The natural growth rate

V. ENVIRONMENTAL IMPACT ASSESSMENT
The subproject would contribute to meeting the demand load and power safety in Hanoi city
and thereby bring about significant socioeconomic benefit. Apart from such benefits, the
subproject may also result in environmental and socioeconomic impacts which are adverse to
the local conditions.
The environmental screening of the subproject indincates that it is eligible for financing
considering that the subproject would not involve possible high risk and would 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, graves and graveyards; (c) water regime, particularly water flow and water quality;
and (d) local traffic.
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,
localized impacts with available mitigation measures. Only OP 4.01 and OP 4.12 are triggered
for this subproject.

households. Impacts of land acquisition are described in detail in the subproject Resettlement
Plan.
2 Long-term land tenure Medium Short-tern,
Long-tern The process of construction of the project will occupy land to build permanent
substations (60,093.0m2) and the road to the substation (3,188.0m2),
the total occupied area is paddy-field where located in Dong Quang commune, Quoc
Oai district, west of Hanoi City.
3 Impact on cultural
heritage, history,
temples, pagodas and
other sensitive areas,
ecological areas in need
of protection
No No The project area does not have the cultural relics, historical temples and other
sensitive areas, ecological areas in need of protection.
4 Erosion and
sedimentation due to
earthwork
Medium Short-tern Earthwork (volume of sand for levelling substation platform:
126,114.0m3 and volume of sand for levelling external road: 7,258.0 m3) occurred
at substation locations in a short time. The project area has flat topography, not
cutting through streams and rivers so the risk of erosion, landslides is very
low
5 The impact on air
quality from
construction activities
and emissions of
Medium Short-tern The constructive activities may cause adverse impacts to air quality:
+ Impacts of waste gases (SOx, NOx, CO ...) arising from the operation of
the means of transport, machinery and equipment. The degree of influence is not

significant due to amount of waste gases is not large and the concentration
of emissive sources is low.
+ Impact of dust: dust generated from digging and leveling operations, transport
operations from the equipment and machinery. The area around substation is
mainly paddy-field and distance from residential areas to position
of project at least 150m. The project only affect the people who
live along the route of road transporting building materials from the provincial
road 80 to substation. Therefore, this impact is considered to be small
and significantly only in the dry season, it is temporary and will terminate at
the end of the construction activities.
6 Noise and vibration
caused by vehicles and
machinery
Small Short-tern In the constructive process, transport vehicles and machinery can cause noise and vibration
affect households along the roads and at the constructive location. However, this effect is
small and will expire after constructive period because of the project applied the mitigative
measures and only occur during the construction.
7 Pollution of soil, air and
water due to leakage of
oil from machinery,
construction equipment
Medium Short-tern - Leaking oil from machineries, transport equiments can affect the environmental quality of
land and water, especially during the rainy season, the leaking oil can spread under water
overflow affecting quality of soil and water at the surrounding area...
- Transformer oil or oil having PCBs might also be leakage to the environment due to
accidents. However, oil having PCBs to be used at substation are prohibited by the national
regulation.
- The operation of the substation will use some chemicals available in such equipment as
battery, insulating oil, grease oil and etc., but in small quantities.
8 Inpact on quality of the
environment from the
disposal of waste.
Medium Short-tern
to average
These wastes include construction and household waste that can cause adverse impacts on
environmental quality. During the process of project construction, all types of construction
waste must be planed to collect, sale and proper disposal (leveling).
For household waste arising from the operation of the workers will be collected and
disposed of in the proper place. However, should set up a appropriate monitoring plan to
ensure the waste is collected and handled according to regulations.

material storage
Medium Short-tern
to average
The project is needed to have some storages (closed and open) containing construction
materials for substation and must construct workers' camp for the workers can take a rest at
there
The camps and warehouses containing materials can cause risks to the safety and health of
the local population and construction workers due to the stored material and equipments is
unsafe, this can arise a conflict between the workers and the local population.
Workers will be recruited from local population, the camps will have mobile toilets and
equipment, construction materials have been designed layout at the right place, security
surrounded. So conflict with local population and impact on the health and safety from the
camps and the storage is very small degree.
10 Conflicts arise between
construction workers
and local people
Small Short-tern The focus of large amounts of construction workers (maximum 70 people) will arise a
conflict between the workers and the local population. However, the main contractor will
hire local workers for the suitable jobs so the impact of this is minor and can be mitigated.
12 Impact to cause damage
the system of local
roads because of
construction activities
and transportation of
building materials
Medium Short-tern The position of project is located nearly the inter-commune and inter-hamlet roads, the roads
covered with thick plastic for convenient transportation of building materials. Moreover, the
scope of the project are relatively small, the level of activity of the transport is not high, thus
damaging impact on local roads due to the construction of the project is not significant.
Construction contractors will be working with local authorities in the use of local roads to
transport equipments and materials.
THE PERIOD OF OPERATION
13 Effect of excessive
electromagnetic
intensity
Medium Long-
term
If not properly designed and constructed the substation and
the connection lines would have adverse impact on worker and
community health. Calculation results and actual test in the existing 220kV substation
and transmission line show that the intensity of the electromagnetic field is much lower than
the permissible level 5kV/m. Therefor, it does not affect health of human. 220kV Tay Ha
Noi substation is designed to comply with the codes and safety regulations, safety rules.
While working will also be strictly applied to the operational staff to ensure electromagnetic
safety.

In the period of project design, the safety measures have been implemented. However,
electric shock and effect on safety of local residents and workers who operate the sunstation
still has the possibility of failure to comply with security measures.
17 The risk of fire due to
oil leak Medium Long-
term
The project is likely to increase the risk of fire due to leakage of transformer’s oil or the
explosion of transformer. However, the risk of fire is minimized by the substation was
equipped with oil collecting pit to contain all the transformer’s oil when the transformer is
damaged, the fire fighting equipment as automatic fire alarm system, water sprayer...
18 Pollution caused by
leaking oil and toxic
chemicals
Medium Long-
term
The oil leaking from the transformers can adversely impact on environmental quality of soil,
water, air . To prevent adverse impacts on the quality of the environment by oil leakage, the
oil collecting pit was designed to recover all the oil leaks due to the breakdown of the
transformer. The oil collecting pit is construced by reinforced concrete placed
monolithically with transformer’s foundation and anti-fire wall’s foundation and higher than
0.3m in comparison with the substation’s surface, the pit bottom is created slope I = 0.5 % in
the direction of the oil conllection tube . The breakdown oil tank is buit in the ground by
reinforced concrete, cement plaster, the tank’s cover is higher than 0.15 m in comparison
with the substation’s surface. The breakdown oil tank is arranged in convenient location for
the collection of transformer oil . The tank’s capacity is V = 100m3 to ensure collecting 100
% of oil go out of the transformes when there is a problem . The breakdown oil (if any) will
be collected in oil collecting pit and flow under the oil drain pipe to the breakdown oil tank
located in the substation.
Required insulating oil of transformers is not included PCBs other toxic chemicals
19 Noise from process of
substation operation Small Long-
term
Transformers are manufactured in accordance with the order prescribed noise levels , the
noise shall not exceed 70dBA at a distance of 3m and installed properly technical
requirement to restrict noise. Since the substations located in industrial zones so the impact
of noise is negligible.
20 Impact of domestic
wastewater and solid
waste of operation staff
Small long-term During the operational period, the project does not generate hazardous waste. For municipal
waste arising from the operation of the substation's operators, the project was designed to
build a septic tank under the toilet to treat before release, the solid waste is collected and
disposed in according to locally common system of garbage collection. Therefore, the impact
