In the first phase (Phase 1): The switching substation only invests in 220kV
distribution system.
In future (Phase 2): upgrade to 220kV substation regarding additional load
situation, install 220/110/22kV transformers and 220kV, 110kV feeder bays.
* Accordingly, these activities may cause adverse impacts to environment and
local communities during the construction and operation period.
As regards the policies of the World Bank (WB), this subproject is categorized
into group B that have to prepare Environmental Monitoring Plan (EMP) based on
Environmental Social Management Framework (ESMF) of the TEP. In which, the EMP
is in line with the EIA established by the working team of the Engineering Consulting
Joint Stock Company 4 based on legislation and technical regulations of Vietnam.
This EMP report includes information about: subproject description, legal
framework of Vietnam and policies of WB, applicable legislations and environmental
technical regulations applied, potential positive and negative impacts, proposed
mitigation measures that are planning to be implemented during the preparation –
implementation – operation phase. The mitigation measures proposed in the EMP will be
integrated in the tender documents and contracts, together with environmental monitoring
during the implementation process.
Under the provisions of the Government of Vietnam, the "Phuoc An Switching
Station" subproject shall have to establish Environmental Impact assessment (EIA), and

2.2 . World Bank Safeguard Policies
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) 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 trans boundary and
global environmental aspects. EA considers natural and social aspects in an
integrated way.
- This subproject triggers OP 4.01 because it involves the rehabilitation, upgrading,
and operation of a high-voltage overhead transmission line, 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’s
EIA and EMP have been disclosed locally at the subproject sites and at the
Bank’s InfoShop 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 the Vietnam Development
Information Center on April 18, 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
TEP - 220kV Phuoc An Switching Station FS
Powering Engineering Consulting J.S Company 4 4
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 on January 24th
, 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 subproject final RP was
disclosed locally at the subproject sites, at the Bank’s InfoShop, and the Vietnam
Development Information Center on April 18th
, 2014.

Auxiliary work items are located within the scope of land acquisition of the
switching substation.
Main auxiliary work items:
* Roads:
- Road within the substation: road surface structure is unreinforced concrete with
the width of 4m, road sides is plaid concrete bar M150 and arranged rainwater collection
pits along roads.
- Road accessing to the substation with the length of 1,372.48m are upgraded from
the existing soil pathway (due to local people exploit soil, rock and crops in the area). Its
starting point is connected to the existing concrete road. Its ending point is the gate of
Phuoc An 220kV substation. Surface structure of the access road is ballast crushed stone,
the width of each roadside of 0.5m, the width of road surface of 6m. Slope towards 2
sides according to cross section is i=2%. Along the road, there are some culverts to avoid
blockage of the natural drainage system.
Currently, this dirt road are being using by several local people to visit their
production forest land (mostly planting Acacia) which is located near the project area
mainly by foot or rudimentary transportation means such as bicycle and motorcycle.
Moreover, due to characteristic of Acacia, the owner does not need to neither frequently

visit nor take much care over the land. In case resident needs to transport product from
their land, they normally use the two communal near the project area. Accordingly, the
traffic density in this road is quite low.
* Power and water supply for the subproject construction:
- Power for the substation construction will be bought from the existing power
source. Power supply for construction sites will be provided by cable and circuit-breakers
switches.
- Water for the substation construction will be provided from 50m-deep drilled
wells within the substation. In the future, it will be used for operating the substation.
Water will be pumped into water tanker and container. Then it is drained to the
construction sites by soft plastic pipes. In which, water will be treated to reach acceptable
quality before supplying to staff as drinking water. In practice, drinking water is often
filtered water bottled in 20-liter tanks which are supplied by nearby grocery store.

The construction activities may cause adverse impacts on air quality:
- Dust: released by excavation, filling & leveling for construction main work items in the
substation and auxiliary work items.
- Dust, SOx, NOx, CO…: released by equipment, machines and material transportation
activities.
- The substation construction area is located far away from the crowded residential areas. The
construction time only lasts about 12 months, thus this activity only causes temporary impacts
during the construction period and it will end when the subproject construction completes.

- The transportation of machinery, equipment and material will increase traffic density
that lead to higher risk for accident. The scope of impact will be along the service roads to
transport construction materials, machinery and equipment for construction phase,
including: the road to the station (construction - operation road of the subproject), and a
few other roads in the subproject area. In which, the provincial roads, communal roads
will be used to regularly transport, including transporting construction materials (cement,
steel ...), commodities such as food. The route from the Da Nang port to the subproject
area will be primarily used to transport steel, over-size and over-weight equipment
- However, the purpose of transporting vehicles will be more reasonable regulated, and
the over-weight device will be ship by specialized vehicles, so that the impact will be
minimized.

Insignificant
impact
Short

The access road will be upgraded from a dirt road which is being used by a few
households to access their land, this may lead to inconvenience to transportation of some
households but proper measure will be taken place to minimize the impact.
- As mentioned in the section 3.4.3, the area surrounding the substation is mainly
production forest land (milpa) of local people (mostly planting Acacia). Due to the
characteristic of Acacia, the owner does not need to visit their land frequently. In
addition, the existing road is quite small (1-1.5m) that cannot be use for transportation
of big and bulky vehicle. Instead, to transport with these transportation means (car,
truck, etc), local people usually use the two communal roads (see the annex 2).
Accordingly, the traffic density on this road is very low.
- During the construction, the PO will conduct appropriate measures to regulate the
traffic and minimize the risk of accident. In fact, the road is designed in accordance
with national standard, in which the width of 7m (including pavement) is suitable with
the expected traffic density of this road. In addition, the length of this road is relatively
short therefore the constructor can easily arrange measure to minimize impact of
material transporting and transportation of construction vehicles/machines.
Accordingly, there is no need for passing section or U turn along this road.
- Taking all of these reasons into consideration, the construction of the access road is
unlikely pose significant impact to transportation of local residents.
12 Risk of localized
flooding
Medium Short
term
- According to the design, there is a regularly dried stream at the proposed substation
location. Therefore, the construction of the substation will affect this stream that lead to
the risk of logging this water way. Likewise, the access road will pass through several
canals and small dried water streams that may cause localized flooding in this area.
- Accordingly, there are some technical measures have been studied and proposed to

13 Impacts on
worker’s health
and labor safety,
social order and
security in the
subproject area
Insignificant Short
term
Concentration of workers (about 90 people) will increase temporarily population density in the
subproject area, and simultaneously increase risk of infectious disease spreading and
transmission from local people to worker and vice versa such as: malaria, hemorrhagic disease,
etc. However, workers’ health will be examined periodically and equipped with medicine
cabinet. Thus, impact is insignificant.
- Impact on local social order and security: the concentration of workers can affect social
order and security of the locality due to:
+ Conflict between workers and local people during the construction process can occur
due to the difference of habit, practice and custom.
+ Workers can violate regulations of the locatity.
+ If workers are not managed strictly, it can arise social evils.
+ Workers can violate traditional, cultural and religious places of local people.
However, workers will be disseminated, propagandized regulations, and practices and
customs of the locality, thus this impact is insignficant.
- Besides, during the construction process, accidents which can occur for workers and
local people include: accidents in the construction process, traffic accidents on
transportation roads, accidents due to landslide, rock collapse, fire and explosion,...
Thus, it needs to have labour safety measures for workers.
- Last but not least, untreated water if provide to workers of staff may affect their health.
OPERATION PHASE

Insignificant Short
term
Volume of domestic solid wastes released by each worker is estimated about 0.3 – 0.4
kg/person, therefore total volume of domestic solid wastes (called rubbishes) released by
operators will be about 3.6 kg/day.
- Almost rubbishes are decomposed easily. They will be collected daily in dustbin in the
switching substation area and poured periodically in rubbishes dumping area of the
locality.

process
Insignificant Short
term
During the operation process, accidents can occur due to fire and explosion or electric
shock. These risks will impact directly on operators in the substation.
18 Risks of fire and
explosion,
electric shock
Insignificant Short
term
Risks of fire and explosion, electric shock can occur in the switching substation during
operation phase. Main reasons causing risks will be that operators will not carry out and
comply with regulations during the operation process, people will be lack of awareness of
danger of high voltage network, thus they will violate the substation area.
+ Electric shock: When operators will not strictly comply with safety regulations on
electric equipment operation and use, risk of electric shock can occur.
+ Fire and explosion: this risk can occur due to short circuit or overload or lightning
strike. Risk of fire and explosion due to electricity will only occur in-place and

Conclusion: After the step to study the potential impacts, it is proved that the subproject will not cause significant negative
impacts to (a) natural habitats or protected areas, including conservation area; (b) the cultural and historical sites, including valuable
archaeological (prehistoric), paleontological, historical, regional and cultural sites; (c) hydrology, particularly the flow; and (d) other
significant impacts on the environment and society. Accordingly, the subproject was categorized into Group B which is eligible to
make loans concerning the rules and policies of the World Bank.

monitoring program shall have the following objectives:
- To determine the extent of the actual impact.
- To control the impacts from the construction process and indicate it in the EMP.
- To check and monitor the implementation of environmental protection measures
during the construction phase based on the EMP.
- To propose mitigation plan for unexpected situation.
- To evaluate the effectiveness of the mitigation measures in the different phases: pre-
construction, construction and operation; and suggestions for improvement.
Safety-environment officers shall have to refer some information/documents as
follows:
- Report on environmental performance of contractors, and implementation plan of the
EMP.
- To practice good environmental mitigation measures.
- Complying with the EMP requirements in accordance with the law.
- Protect sensitive sites, especial protected areas.
- Control soil erosion and landscape
- Measurement on atmospheric conditions.
- Mitigating measures to control pollution of the constructor to reduce impacts on
