RAPID TECHNO-ECONOMIC FEASIBILITY REPORT FOR
DEVELOPMENT OF COLACHEL PORT AT TAMILNADU
FINAL REPORT
• Quarry and construction materials shall be covered with sheets/enclosed during transportation and storage
to avoid dust generation;
• Dust suppression techniques (e.g. wetting down, use of all-weather surfaces, use of agglomeration
additives) for roads and work areas, optimisation of traffic patterns, and reduction of travel speeds;
• Exposed soils and other erodible materials should be re-vegetated or covered;
• New areas should be cleared and opened-up only when absolutely necessary;
• Loading, transfer, and discharge of materials should take place with a minimum height of fall, and be
shielded against the wind, and consider use of dust suppression spray systems;
• Hardened roads should be laid in the area to avoid dust generation due to vehicular movement;
• Solid wood barriers or wind screen fabric should be used around the perimeter of construction site to
avoid impact on neighbouring communities due to dust generated from construction activities;
• Dust suppression techniques (e.g. wetting down, use of agglomeration additives) for roads and work areas
should be applied;
• Good maintenance of vehicles and equipment according to a periodical repair/revision programme;
• Use of good quality fuel and lubricants;
• Daily cleaning of access ways in the neighbourhood of work sites (removal of earth and sand) to prevent
dust;
• Collection and temporary storage of sanitary and cleaning wastes, as well as garbage, in containers;
• Only Vehicles having Government license and PUC certificate for transportation of construction and quarry
materials should be used;
• Energy conservation measures can enhance efficient energy consumption patterns and consequently
affect the GHG emissions impacts in a positive manner.
If adequate measures such as sprinkling of water on haul roads around sites where clearance activities are on,
covering material trucks especially those carrying sand and borrow materials etc, then the impacts can be
reduced to a great extent. The main source of dust generation is due to site clearance activities, removal of trees
and loading/unloading of construction material.
To mitigate the dust generation, following suitable mitigation measures shall be applied:
• Sprinkling of water shall be carried out.
• Asphalt plants, crushers will be sited at least 1.0 km in the down wind direction of human settlement and
other sensitive receptors along the project corridor.
• During and after compaction of the sub grade/sub base water will be sprayed at regular interval in order
to avoid dust generation.
• Vehicles carrying fine and coarse aggregate should be covered with tarpaulin in order to avoid the spills
on the existing road.
Exhaust gas emissions are anticipated from construction plants, vehicles, etc. So in order to mitigate the exhaust
gases, all the vehicles should be warranted with certificate proper maintenance of the vehicles shall be followed.
Operation of the port itself is not anticipated to result in any significant air quality impacts. The following
measures could mitigate the anticipated negative impacts on the ambient air quality:
