1. INTRODUCTION

“Phuoc An switching substation” is one of the subprojects of the Transmission

Efficiency Project (TEP) financed by the World Bank (WB). This subproject is in line

with the national Power Development Master Plan 7 (PDMP7), approved by the Prime

Minister in 2011. Moreover, it will contribute to meet the objectives of the National

Energy Development Strategy guiding the power sector up to 2020 (Prime Minister

Decision, December 2007) to reduce investment needs in the power sector, strengthen

energy security, control and mitigate environmental pollution by energy activities

and foster socioeconomic sustainable development. The proposed subproject will also

contribute to the implementation of the Socioeconomic Development Plan (SEDP) 2011-

2015, which aims for sustainable economic growth on the basis of improving quality,

effectiveness and competitiveness.

According to plans, Phuoc An 220kV switching station is going to be built to

connect the 220kV lines in Binh Dinh province for the period of 2015-2020. In future,

this station will be the load station to meet the load demand on the rise of Binh Dinh

province and to share the load for 220kV Quy Nhon substation (the existing station

cannot be expanded).

The subproject is planned to be located at Dai Hoi Village, Phuoc An commune,

Tuy Phuoc District, Binh Dinh Province.

Main works:

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



the EIA of the subproject was approved in April 2014 by Decision No. 1176/QD-UBND

of the People's Committee of Binh Dinh province.

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



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.

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.

to the

construction of

the access road

Insignificant

impact

Short

term

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

ensure the ability of drainage of this area (chapter 6 and appendix 2-3)

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

14 Impacts due to

and referred with standards IEC.

- Operation work of the substation will be complied with regulations of power sector.

15 Impacts due to

domestic solid

wastes

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.

16 Impacts due to

hazardous

wastes

Insignificant Short

term

- Periodic maintenance and repair process of the switching substation will release wipers

with oil and grease. Volume of wipers will depend on repair and maintenance activities.

17 Labor accidents

/risks can occur

during the

operation

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



No Impact Decree of


immediately (in very short time) because when risk occur, relays located in the substation

will auto-disconnect. However, fire risks can occur and spread, if not fight fire timely

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.

8. EMP IMPLEMENTATION

8.1 Responsibility to implement EMP

During the construction phase, the CPPMB will assign the construction

supervision consultants (CSC) and/or field supervision engineer that is responsible for

supervising contractors on the implementation of daily mitigation measures. Monitoring

results will be taken and reported, and staff that is responsible for safety regulations of

the CPPMB will have the responsibility to ensure that activities related to safety policies

are fully recorded and archived.

Environmental management during the construction process requires the

involvement of stakeholders and each of them has their own responsibilities, including:

NPT, Project Management Board, Department of Natural Resources and Environment of

Binh Dinh, contractors, consultants, construction supervision, and local communities.

The World Bank will conduct periodic monitoring, tracking and logistics control

at both the subproject level.

To ensure the implementation of the Environmental Management Plan to be

effective, the following activities will be carried out during the subproject

implementation:

a) During the detailed design stage and prepare bidding documents:

- During detailed engineering design and prepare bidding documentation for each

contract, design engineering consultant will integrate takes into Environmental Code

bidding documents and contracts and the specific measures proposed in the EMP of the

subproject.

- During the process of preparing bidding documents and contracts, contractors are

aware of the requirements to ensure safety and compliance commitments.

b) During the construction phase

The CPPMB will assign the Construction Supervision Consultant and/or Field

Engineer to be responsible for the daily oversight of contractor compliance on the

implementation of safety measures. General terms of reference for this task are presented

in the Appendix. Construction Supervision Consultant and/or field engineers will

perform, but not limited to, the following tasks:

- Before starting construction, the land compensation have to be carried out, the

removal and/or acquisition/donation of land has been completed.

- Review and approval of the environmental management plan is prepared on site

by the contractor prior to starting construction.

- During the construction process, closely monitor the implementation of measures

to minimize environmental impact.



- Verify the compliance with commitments of the environmental management

plan, check for any damage caused by the contractors. If necessary, ask the contractor to

compensate/restore construction areas as required in the contract. The implementation of

mitigation measures and safety will be presented in the progress report.
