New Delhi (10.08.2023): NLCIL Thermal Units and Mines are certified for Environmental Management System ISO:14001, complying to the environmental stipulations. NLCIL is equipped with the required Effluent Treatment Plants and is ensuring its continuous operation to meet the standards prescribed by Central Pollution Control Board (CPCB), Ministry of Environment, Forest and Climate Change (MoEF & CC), Tamil Nadu Pollution Control Board (TNPCB). The quality of treated effluent is being regularly monitored by TNPCB, latest being done on 30.06.2023, in which parameters are within the permissible limits. In addition, third party analysis of water samples is also being carried out, as per the Environment Clearances (EC) conditions stipulated and the same are being submitted to TNPCB & MoEF CC. All the effluent parameters are within the permissible limits.
Regular monitoring of the Ambient Air Quality by TNPCB, in-house NABL accredited lab & third-party laboratories are also being conducted periodically to ensure the efficiency of the emission control measures. In addition, Continuous Ambient Air Quality Monitoring Stations (CAAQMS) are installed to monitor the real time Ambient Air Quality as recommended by TNPCB. The values are well within the permissible limits.
Comprehensive study on combined effects due to all the power plants operated by NLCIL was also carried out by M/s Centre for Environment, Health & Safety (Annamalai University – an accredited Environmental Impact Assessment (EIA) organization under National Accreditation Board for Education and Training (NABET) by Quality Council of India (QCI) for MoEF & CC recently in 2022 and all the Environmental parameters at ambient level are within the permissible limits.
Combined Water Management Study including all Thermal Power Plants, Mines and Township was also carried out by M/s Centre for Environment, Health & Safety (Annamalai University – an accredited EIA organization under NABET by QCI for MoEF&CC) recently in 2022. The report has analyzed all the sewage & effluent treatment facilities and confirmed that all the water parameters are well within the permissible limits.
The effluent analysis & Bottom ash analysis reports depict that all the parameters are well within the permissible limits. Centre for Applied Research & Development (CARD) a NABL accredited lab is periodically testing the requisite parameters in the environment which are within the permissible level.
