What is meant by Environment?
It is the surrounding in which we live; land, water,
atmosphere, animals, trees etc, which can be affected
by our activities
All our activities produce waste in solid, liquid &
gaseous form, which if discharged to the environment
in excess quantities beyond its assimilation capacity
can lead to pollution
Introduction

3. 3
Environmental Policy
DaewooEngineering & Construction Co., Ltd. recognizes that the
Earth environment is essential and will comply with the following
environmental policy for planning and conducting the construction
business for human survival not only for present but also for future
generation.
Environmental Management Point
Minimize construction waste, effluent and promote recycling
Prevent environmental pollution
Provide adequate information, training and supervision
Measure, monitor and review environmental performance

4. 4
This is a state in which the environment is
contaminated with toxic materials, discharged by our
activities, which are harmful to the flora, fauna &
living beings
-Air Pollution
-Water Pollution
-Land Pollution
-Noise Pollution
What is Pollution?

5. 5
What is meant by spill?
This refers to the sudden or accidental discharged of contaminant
into the environment
Spill Control Plans
Three processes are in place for effective management of waste water
to avoid land surface and ground water contamination.
-Batching plant process water
-Treatment of batching plant toxic waste water before discharge
-The high pH value is neutralized with the use of Aluminum Sulfate
Spill

6. 6
•Battery charging operation
-Sulphuric acid is being neutralized with soda ash before
disposal
•Materials for Clean-up & Control
-Saw dust
-Dry sand
-Rags
-Oil boom
-Absorbent Pad
Use Of Absorbents/Neutralizers

7. 7
Once a spill is noticed:
Shout spill! Spill!! Spill!! To attract others
-Notify all concerned (Including HSE)
-Identify source of spill or leaks
-Stop source of spill
-Contain spill
-Clean-up
-Disposal of contaminated materials
Spill Response Guide

8. 8
Release To Water or Soil Contamination
Oil Diesel
-Call departmental manager on channel
xxx.
-Call safety on channel x
-Call Company emergency unit on
channel xx
-Identify the source/shut down the source.
-Contain the spread
-Arrange for clean up
-Follow disposal procedures
-Make written report

Left over materials from
the office, site and camps
that are not useful in its
present state and needs
to be disposed off
What Is Waste?

Waste Management Tips
Reduce production of waste
Segregate waste
Recycle waste
Disposed off waste
Conserve resources

16. 16
Waste Management
Waste management aim is to gradually reduce
waste with the aim of eliminating those that have
the potential to cause harm to people and the
environment.
It is criminal offence to dispose hazardous waste
to nature or cause harm to the environment.

17. 17
Environmental Control
Dust Pollution during Construction Phase
Adequately sprinkle the area with water especially the road
under construction to suppress or minimize dust. Water
sprinkling of construction areas shall be done twice a day,
morning and afternoon on a regular basis.
Body of Water
Protect all forms of body of water around the site that will
be affected during the construction period this includes river,
sea, swamp or lakes.
No waste water coming from the construction site will be
discharged to this body of water without proper treatment or
tested to be safe and will not harm any form of living things
in the environment.

18. 18
Environmental Control
Noise Control
Administer a continuing, effective hearing
conservation program, as described in the
procedure, whenever employee noise
exposures equal or exceed an 8-hour time-
weighted average sound level of 85 decibels
measured.

19. 19
Environmental Control
 Hazards of Exposure to noise
–Exposure to noise can have the following consequences;
–Causes annoyance and irritation
–Affects concentration and efficiency
–Causes fatigue and accident proneness
–Prevents ear from registering other sounds, instructions and
warnings
–Short exposure to excess noise causes damage to the inner
ear and permanent loss of hearing

20. 20
Environmental Control
 Limiting Exposure to noise can be reduced by:
–Engineering and control methods (e.g. installation of
silencer, sound controlled equipment enclosure, replacing
equipment with a low noise producing equipment if
possible)
–Job rotation
–Providing rest rooms or acoustic refuges
–Re-arranging work locations
–PPE (ear plug, ear muffs)

21. 21
Environmental Control
Soil Erosion
The excavated or embanked area, shoulder on side slopes or
borrow pits are the area where soil erosion are likely to occur
during heavy rain. To avoid soil erosion, all exposed surface shall
be regressed or covered by stone pitching, lining concrete, spill
way and compaction of the embankment area shall be carried out.
Operating Procedures:
The operating procedures for various operations such as Acid
neutralization, Auto Effluent Grease pit operation, Batching plant
effluent neutralization should be displayed at the corresponding
locations. The operating personnel in the corresponding locations
should be trained to operate the above procedures.

22. 22
Summary
Minimizse construction waste, and then dispose it to the
designated area
Implement waste segregation ang recycling
Minimize the source of pollution by establishing target of
saving energy and resources
Strive that there is no environmental accident and
violation of environmental legislation and regulation
Environmental policy shall be open to the public as well
as internal
Each employee should understand and comply with the
policy, and shall actively participate in and make utmost
efforts to the environmental management activity
