Fly Ash Pollution of nearby water bodies had forced the Orissa State Pollution Control Board (OSPCB) to issue a notice to the massive 3000 MW NTPC Talcher Thermal Power Plant.While the notice asked for immediate shutdown of 4 untis of 500 MW,NTPC has only closed down 1 unit citing that closing more units will lead to massive power disruptions in nearby states.The action comes following NTPC bad fly ash managment system which has led to two past incidences of water pollution.There was a danger that the massive amounts of fly ash being generated would lead to breakdown of the storage dykes and lead to more pollution.
