Enayam Port

Tamil Research Institute
RAPID TECHNO-ECONOMIC FEASIBILITY REPORT FOR
DEVELOPMENT OF COLACHEL PORT AT TAMILNADU
FINAL REPORT
5. SCREENING OF POTENTIAL IMPACTS AND MITIGATION MEASURES
From the previous analysis of main the environmental characteristics of the territory and once the best alternative
has been chosen, the present chapter will analyze its main component to address the main environmental
impacts expected with the implementation and operation of the Enayam option and the recommended mitigation
measures.
Thus, the screening of the potential impact analysis will follow the main components of the environment , land,
water and socioeconomic environments, and the effects of the proposed port solution onto them.
5.1. LAND ENVIRONMENT
5.1.1. Air quality
5.1.1.1. Transportation and Cargo Material
Some of the project activities (site clearance, dredging and reclamation, construction of breakwaters,
construction of port infrastructure, traffic during construction and use of heavy machinery construction of road and
rail) will generate air pollutants like NO 2 , SO 2 , HC, CO, PM, VOCs, etc. This has the potential to cause
temporary impacts on the air quality.
According previous studies, the baseline concentrations of Particulate Matter, SO 2 , NO 2 and CO are within the
limits of NAAQS stipulated by MoEF/CPCB. With the present background concentrations of air quality
parameters, it is expected that there will only be a mild build-up of air pollutants. Further, because of the
prevailing strong winds along the coastal region and the resulting dispersion the impact on air quality from
pollutants would be reduced. Towards land ward side all is green with complete coverage of coconut and other
trees (green barrier) will also nullify any air pollution impacts. In addition, adoption of suitable mitigation
measures will ensure that these impacts are rendered insignificant.
The following activities may cause air pollution during construction phase:
• Material sourcing at Quarry
• Material and equipment transport
• Stone crushing operations in the crushers;
• Handling and storage of construction material;
• Concrete batching plants;
• Asphalt mix plants due to mixing of aggregates with bitumen; and
• Construction and allied activities.
5.1.1.2. Quarrying
Will be necessary quarrying blasting, drilling, digging, road transport, use of heavy machinery for hauling and
loading, storage and handling of fuels, etc. This will generate dust and other air pollutants like NO 2 , SO 2 , HC,
CO, PM. This will affect the ambient air quality.
The choice the quarry site will avoiding nuisance for the public is required. Prior to commencing the works the
contractor should establish the environmental baseline conditions in the specific area around the selected quarry.
