Ecosmart has completed a comprehensive Environment Impact Assessment (“EIA”) study assessing the likely environmental impact from implementation of the project and has suggested measures to mitigate the detrimental impacts on the environment as well as to portray the beneficial impacts due to construction and operation of the generation plant

A brief description of the EMP proposed to be employed by the Company to mitigate any adverse environment & social impact due to implementation of the generation plant is as follows:

1) Afforestation & Development of Green Belt

Establishment of the generation plant involves diversion of 77.87 Hectares of forest land in Chandrapur Reserve Forest area In lieu of the same, Government of Tripura would undertake compensatory afforestation of 155.74 Hectares of degraded forest land under Kakraban forest range, i.e. twice the area of the project site. The payment for the above has already been made by OTPC to the Forest Department and has been included as part of the project cost. It would also undertake development of 28 Hectares around the Plant as a green belt

2) Exhaust gases

Each HRSG would be provided with a 60 m high self-supporting stack. The stack height would assist better dispersion of hot flue gases from HRSG and NOX emission. Negligible air pollution is anticipated due to use of Dry Low Nox (DLN) burners. No sulphur emissions would take place due to use of natural gas as fuel

3) Effluent Treatment

The cooling water blowdown would generally be free from chemicals and have a temperature lesser than the ambient temperature. Considering the quality & quantity of blowdown water, it has been envisaged to pump back the CW blowdown to the River Gumti on the downstream side of river intake point through a cross-country pipeline. The HRSG blowdown would have high Total Dissolved Solids (TDS) and a higher temperature as compared to ambient temperature. In view of this, it would be diluted with CW blowdown before discharging into the river. The waste effluents from neutralizing pits, GT compressor water wash, drains from chemicals lab etc. would be collected in a central monitoring basin for dilution and monitoring the quality before utilizing the same for horticulture purposes

Environment Monitoring

OTPC would deploy a well-defined environmental monitoring programme with trained and qualified staff to monitor the ambient air as well as stack gas quality and ensure that the quality of emissions is maintained within prescribed limits.

The scope of services of Ecosmart involved completion of an environment & social impact assessment study together with finalization of a comprehensive Environment Management Plan (“EMP”) for the project. An Environmental Mitigation & Management Plan (EMP) has been prepared and the company has appointed M/s Ecosmart India Limited (“Ecosmart”) as the Environment consultant for the project. Ecosmart is a leading environmental management services and advisory firm promoted by IL&FS.
