In a bid to curb water and soil pollution due to industrial discharge, the government has notified a revised standards for common effluent treatment plants (CETPs) being operated at various industrial clusters across the country.
The environment ministry notified the revised standards on January 1, 2016. “The revised standards will help in significantly improving the performance of CETPs through implementation of design inlet quality, addressing the problems of the coastal pollution due to industrial discharges and keeping a close watch on the impact of discharge of industrial effluent on soil and ground water quality,” the ministry said in a statement on Friday.
Besides, the new provision entails quality monitoring of soil and groundwater quality atleast twice a year (pre and post monsoon) for studying the impact of disposal of treated effluent on land. “The monitoring of the soil and water quality would be carried by operators of CETPs,” the statement noted. However, the mode of ‘discharge into sea’ by CETP which provides very high dilution will qualify for a relaxed norm on permissionable discharge.
The environment ministry has also empowered the state pollution control boards to prescribe standards for inlet quality of effluent in respect of Bio-chemical Oxygen Demand, Chemical Oxygen Demand, Total Suspended Solids and Total Dissolved Solids.
