2.2. World Bank Safeguard Policies
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, the subproject needs to prepare 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 needs to be disclosed as required by OP 4.01 and the
Bank’s policy on access to information.
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 needs to prepare and disclose a RP. The RP will include 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.
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.
1 The EHS Guidelines can be consulted at www.ifc.org/ifcext/enviro.nsf/Content/EnvironmentalGuidelines.
500kV Tay Ha Noi Substation Environmental Management Plan
Institute of Energy 7
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 of the EHS Guidelines.

of impact
Duration of impact Description of impact
THE PRE-CONSTRUCTION AND CONSTRUCTION PHASES
1 The effects on
the vegetation
and habitat due
to clearance of
substation’s
surface and the
road to
substation
Small Short-tem, Long-term - According to survey results, the project
construction area is agricultural land of
rice of the households in Quoc Oai town
and Dong Quang commune, Quoc Oai
district, Ha Noi City.
- The substation would be located in the
rice fields of 30 households of Dong
Quang commune, Quoc Oai district. All
of 30 households would lose a part of
their land permanently.
- Land acquisition would have adverse
impacts on income and livelihood of the
affected households. Impacts of land
acquisition are described in detail in the
subproject Resettlement Plan.
2 Land tenure Medium Short-tem, Long-term The process of construction of the project
will occupy land to build permanent
substations (63,281 m2). The total occupied
area is paddy-field, Affect agriculture of
120 farming households in Quoc Oai town
and 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 Safety risks
related to UXO
Medium Short- term The existence of UXO is confirmed by
Command in substation area. There may be
at higher risk of the existence of UXO in
the substation area. However, the project
area is located on the agricultural land area
cultivating rice in the long-time of the local
people, so safety risk related to UXO is
considered moderate and UXO clearance
(if needed) will be carried out by qualified
agencies.
5 The impact on
air quality from
construction
activities and
emissions of
transport
vehicles and
Medium Short-term 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
500kV Tay Ha Noi Substation Environmental Management Plan
Institute of Energy 16
machinery in
the constructive
period.
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 700m. The project only affects the
people who live along the route of road
transporting building materials. 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 mitigation 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
equipments 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 Impact 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.
9 Impact on
health and
safety from
construction
camps, material
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
500kV Tay Ha Noi Substation Environmental Management Plan
Institute of Energy 17
storage 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 equipment 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 40 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.
13 Impact to
transportation
Small Short-term - Impact to transportation can be defined as
increasing traffic due to car transforming
material in the Day River dike, especially
in road access to substation, can cause
temporary congestion and nuisance to local
people. The breaking of the current traffic
pattern and can increase the risk of
accidents.
- The substation is located in an open area,
the transportation of construction materials
is generally easy due to relatively
developed traffic system in the subproject
area, so the impact is assessed small.
THE PERIOD OF OPERATION
14 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 500kV substation
and transmission line show that the
intensity of the electromagnetic field is
500kV Tay Ha Noi Substation Environmental Management Plan
Institute of Energy 18
about 0-7KV/m for electric field and 0 –
4.5 A/m for magnetic field. When 2
substations operate at the same time,
electromagnetic would be increase twice
with highest value of 10KV/m and 9 A/m.
However, high-intensity electromagnetic
fields usually appear only in the cutter,
disconnector. Thus, the operator working at
stations will be affected by the electric field
but the operators mainly work in the
control room, do not work constantly in the
power sector intensity of the
electromagnetic field. Moreover, they will
be equipped with protective equipment,
health care annually. Then, impact of the
electromagnetic field to the workers are
still in allowable limit... 500kV 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.
15 The risk of
interference
with radio,
television or
other forms of
contact
No impact No impact The project’s location is away from the
radio communication works
16 Safety and
health effect and
the risk of
electric shock.
Medium Long-term 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 substation 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 firefighting
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
constructed 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
500kV Tay Ha Noi Substation Environmental Management Plan
Institute of Energy 19
the oil collection tube . The breakdown
oil tank is built in the ground by
reinforced concrete, cement plaster. The
breakdown oil tank is arranged in
convenient location for the collection of
transformer oil. The tank’s capacity is V
= 155m3 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
on environmental quality due to the
discharge of wastes considered negligible.
21 The breakdown
of grid
incidents,
occupational
accident, in the
process of
operation
management.
Medium long-
term
During the process of management,
operation, repair and maintenance works,
the breakdown of grid incidents and
accidents can occur if the operator and
maintenance personnel do not comply
with safety rules and operation.
22 Working at
high and with
live power
lines
Small Long
–
term
- Workers working below live power
lines and at height on poles and structure
may be at risk, or accident, or electrical
shock in case workers do not conform to
safety and operation regulation.
