Enayam Port

Tamil Research Institute
RAPID TECHNO-ECONOMIC FEASIBILITY REPORT FOR
DEVELOPMENT OF COLACHEL PORT AT TAMILNADU
FINAL REPORT
Anticipated
Impact
Siltation and
eventual blocking
of drains caused
by excessive sand
and silt in the storm
water run-off.
Construction
Sedimentation ponds to the quarrying process.
Surface run-off from the construction site should be
discharged via sand/silt removal facilities such as
sand or silt traps and sediment basins.
Mitigation Measures
Operation
Contamination /
pollution or
modification of
ground water
sources
Study to investigate the change in hydro-geological
conditions, the available aquifers and safe yield levels.
The phreatic aquifer should not be affected when
aquifers are exploited.
There can be rainwater harvesting and large borehole
diameter where existing people bathing or washing
purely.
Waste water should be treated up to the standards for
discharge (Prevention and Control of Pollution).
Implementation a water quality monitoring programme.
Port operator should be required to develop system for
holding and collecting storm water runoff and surface
runoff produced by site activities and its treatment
before discharge
Treated water will be discharged into sea water after
meeting marine discharge standards prescribed by
MoEF
Changes marine
water qualities
The wastewater and sewage generated at site and at
labour camp will be collected in holding tank and
periodically transferred to nearby Sewage Treatment
Plant . In case of non availability of nearby STP, septic
tank with soak pits is recommended during
construction phase.
Waste water management plan will be incorporated
in the EMP.
Breakwaters shall be constructed in a way to maintain
good tranquil conditions.
Port operators should prepare a Spill prevention,
control, and counter measure plan consistent with the
IMO Manual on Oil Pollution Section II – Contingency
Planning.
All ship related waste with a potential to cause
pollution to the marine environment should be disposed
of according to the guidelines stipulated by the
MARPOL Convention.
Ships used for the project should be registered and will
comply with all international maritime conventions.
Oil and chemical-handling facilities will be located
with consideration of natural drainage systems and
environmentally-sensitive areas.
Fuel dispensing equipment will be equipped with
breakway. Those connections that provide emergency
shutdown of flow should the fuelling connection be
broken by movement.

5.3. SOLID WASTE MANAGEMENT
5.3.1. Potential impact due to contruction
Construction will potentially generate the following wastes: green wastes from vegetation clearance, excess
construction materials, including offcuts and packaging; hazardous wastes; oils, fuels and other chemicals
generated by onsite maintenance and repair of construction equipment and machinery.
Excavation materials; food wastes from construction personnel; site office wastes; and human waste; poor
construction procedures that generate excessive wastes increase construction costs and results in disposal of
