Table 5: Potential environmental issues during the operation

phase

Item Environmental

Impacts

Impact

1

Occupational

Health and

Safety

The occupational health and safety issues

inherent to the operation of transmission

line and substation include hazards due to

exposure to live power lines and high

voltage systems, working in heights and

risks of accidents, and potential exposure

to electromagnetic fields (EMF). Accidents

that may occur include electrocution, fires,

and explosion.

Exposure to Live Power Lines and High

Voltage Systems. Workers may come in contact

with live power lines during the maintenance

of the facilities and electrocution from

direct contact with high-voltage electricity

is a hazard directly related to power

transmission lines and facilities.1

Working in High Elevation. Accidents may

happen when working in high elevation.

However, a worker safety plan may be

implemented to reduce risks that include

testing of structural integrity prior to

proceeding with the work and the use of fall

protection measures.

Worker Exposure to Electromagnetic Fields

(EMF). Electric utility workers have higher

exposure to EMF than the general public

because of working in close proximity to

electric power lines. The occupational EMF

exposure should be minimized through the

implementation of an EMF safety program2

2 Community Electrocution: The community may also be

1 International Finance Corporation (IFC), Environmental, Health, and Safety Guidelines –

Electric Power Transmission and Distribution. 30 April 2007. 2 People’s Committee of Tan Thanh District

10

Health and

Safety

exposed to electrocution hazards as a result

of direct contact with high voltage

electricity or from contact with tools,

vehicles, or other devices that come in

contact with high-voltage electricity.

Exposure to EMF: The transmission frequency

commonly used in transmission systems ranges

from 50–60Hz which is considered as

extremely low frequency3, with impacts

becoming low with distance. The electric

fields become shielded by trees, buildings,

and other materials that conduct

electricity. In general, the electric fields

are strongest close to the source and

diminish with distance.

3

Management of

Hazardous

Waste

Chemicals that are commonly handled in the

transmission lines and substation are

mineral oil in transformers and other

electrical components and liquid petroleum

fuel. There are also potential hazardous

materials and oil spills associated with the

operation of equipment and

retrofitting/maintenance works.

Storage facilities of liquid petroleum fuels

for the generator sets and for vehicles and

other equipment are potential sources of

accidental spills. Oil leak or accidental

spills of hazardous materials could give

rise to contamination of soil and water.

4

Emergency

preparedness

at substation

There are several risks that could occur

with the operation of the transmission line

and substation. Among these are the

likelihood of cable being damaged, corrosion

of the towers over time which could

compromise its structural integrity,

potential fire events, explosion of

equipment, and being hit by lightning.

5

Management

and Control

of Vegetation

at

Transmission

Line

One of the regular programs to maintain the

integrity of the transmission line is the

trimming of tall trees and vegetation along

the ROW. This is being done to maintain the

necessary conductor clearance of the line.

In addition, the presence of vegetation

along the ROW provides habitat for birds.

With reduced vegetation growth along the

ROW, the risk of bird collision on the

transmission line will be prevented.

2.3.2. Environmental Mitigations and Compensation Measures

Proposed in the IEE

15. Proposed mitigation measures for the operation phase are

presented in Table 6. The effectiveness of these measures will

be the focus of future monitoring.
