Panel directs CPCB to monitor it The National Green Tribunal (NGT) has directed a Faridabad based thermal power plant to explore utilisation of fly ash in cement plants and also directed the Central Pollution Control Board (CPCB) to monitor whether covering of the ash dump meets scientific environmental norms. Taking note of a report furnished by the Haryana Pollution Control Board, a Bench headed by NGT chairperson Justice Adarsh Kumar Goel said: “It appears that the exposed surface has been covered and the pond ash is not being allowed to be lifted. The question whether covering of the ash dump meets the scientific environmental norms needs to be cross checked to prevent the potential of any damage by such exercise.”
