CHAPTER-5
ENVIRONMENTAL MANAGEMENT PLAN
The potential impacts of the proposed augmentation of the pumping
facilities have been limited to the pumping stations at Tikri Kalan. The
impact of laying 8 km loop line in Tikri Kalan section is also limited
considering the fact that it is in existing ROU of IOCL and no further land
acquisition is required. Under normal operation, the potential negative
environmental impact of a product pipeline is minimal. Moreover, IOCL
has implemented various measures to further minimize the environmental
impacts. The chapter describes the environmental management measures
taken by IOCL to minimize the adverse impacts.
5.1
Air Quality Management
The Central Pollution Control Board (CPCB) has set standards with regard
to the ambient air quality levels and emission levels. The Suspended
Particulate Matter levels in residential and rural are not to exceed 200
g/m3. The standard for industrial areas is 500 g/m3 where as for
sensitive zone, it is 100 g/m3. The vehicular emission standards for
diesel driven vehicles are Hydrocarbons-2.4 g/k whr; Carbon Monoxide11.2 g/k whr; and Oxides Nitrogen-14.4 g/k whr. These standards will
have to be met, and stipulation to that effect will be provided in
construction contact agreement.
One or more of the following measures may be implemented to minimize
impacts on air quality during construction of loop line and operation of the
pipeline project.

It will be ensured that all the vehicles deployed for the project possess
Pollution under Control (PUC) Certificate.

All vehicles will be properly maintained to minimize emissions of
contaminants, for this necessary measure will be taken.

A schedule for the operation of vehicles will be established to minimize
to the extent practicable, the time of operation of emission sources

Wetting (sweeping or sprinkling) will be used, wherever practicable, to
minimize dust dispersion.

As far as possible unleaded / sulphur free petrol will be used for petrol
driven vehicles.

Good housekeeping, including regular maintenance of equipment and
prompt replacement of leaking pump seals and pipeline valves are
regularly carried out to reduce emissions to a minimum. Wherever
uninterrupted power supply is available, the electrical motors are being
used for pumping. This practice will be continued.
Stacks are provided for releasing occasional emissions from the DG sets.
The stacks for new DG sets at pumping stations will be raised according
to the following formula specified by CPCB.
H = h + 0.2 x kVA
Where,
H is total height of stack required (m)
H is the height (up to rooftop) of building (m) where DG set will be
installed, and
KVA is the total power generation capacity of the DG set.
5.2
Noise Environment Management
The Central Pollution Control Board (CPCB) has set standards for ambient
noise levels in various activity zones. Table 5.1 shows the standard of
noise level in ambient air in different category. Suitable conditions will be
incorporated in the construction contract agreement, to ensure compliance
of these standards.

The following measures need to be adopted to minimize the impact of noise
during construction phase of the pipeline project.

Construction equipment generating minimum noise & vibration will be
chosen.

Workers who are exposed to noise will be provided with hearing protection
like earplug / muffs.

Noise control equipment and baffling will be employed on ventilating
compressors and generators especially when they are operated near the
residential and sensitive areas.

Noise levels will be reduced by the use of adequate mufflers on all
motorized equipment.
Noise level very close to pump house is high. IOCL has restricted manual
operation within the pump house. Noise levels within control rooms are
normal and well within maximum recommended limits.
Nevertheless, the following measures need to be taken to reduce the
noise further.
 Providing ear muffles to employees who attend any work inside the
pump house and
 Growing trees around the pump house.
5.3
Water Environment
There is negligible chance of water pollution, as the total quantity of the
effluents from plant is evaporated in waste water evaporation tank and
nothing is discharged outside the plant. Yet following mitigating measures
should be strictly followed for the proposed Effluent Treatment plan.
a. Treated effluent should conform to the standards applicable for
discharge of effluent to surface water as being practiced in existing
unit.
b. Treated effluent should be utilized for horticulture purposes and green
belt development within the plant as already in practice.
c. Proper functioning (operation & maintenance) of effluent treatment
plant and sewage treatment plant be ensured.

5.4 Land Environment
5.4.1 Top Soil Management
The topsoil present specifically in the loop line is required to be
segregated. Topsoil is segregated as part of the trenching operation in
wetlands, whereas in agriculture lands, segregation is done prior to
trenching. The following practices, as regard to topsoil segregation will be
adhered to during trenching.






Topsoil and subsoil will be segregated during trenching and stockpiled
separately.
Topsoil should be removed to its actual depth or to a maximum of 30
cm as determined by HSE representative for the spread.
Topsoil shall not be used for padding, backfill or trench breakers, under
any circumstances.
Topsoil shall be stored on the non-traffic side of the trench.
Topsoil shall not be used as fill for the trench
After the completion of construction, topsoil shall be spread across the
ROU.
5.4.2 Solid Waste Management
Major solid wastes at pumping stations would be garbage and human
excreta. Garbage is being collected every day and transferred to garbage
bins or container carrier systems for quick removal. Septic tanks up flow
combination is being used for treating the human excreta.
5.5
Socio-Economic Environment
Laying of 15 km MJPL pipeline and capacity enhancement of pumping
station will require a small number of workers to be employed by the
contractor. The contractor shall mobilize local manpower and provide
them clean and sanitation facilities. Supply of clean fuel such as
PG/Kerosene to labourers for cooking shall also be encouraged so as to
avoid loss of green cover and better occupational health of the workers
during construction.
During the operation phase, a small number of skilled and unskilled
workers may get direct and indirect employment, which will have positive
impact on society. Efforts shall be made to recruit local manpower for
pipeline operation and patrolling as practicable.
The other indirect employment opportunities in the area are also likely to
be generated after the project implementation.
