The National Green Tribunal Tuesday refused to quash the environmental clearance granted to 1,320 MW coal-based super critical Khurja Thermal Power Project in Uttar Pradesh saying concerns for air and water pollution have been duly addressed. The green panel said the procedure laid down as per Environment Impact Assessment (EIA) notification of 2006 has been duly followed and detailed EIA report has been prepared by an accredited consultant dealing with all environmental issues exhaustively. "The public hearing was held as per norms and video graphed. In the first meeting, the Expert Appraisal Committee sought clarifications and did not accept the EIA report as it is. In the second meeting, the clarifications were duly evaluated," the NGT said.
