The National Green Tribunal (NGT) directed the Badarpur and Rajghat thermal power plants to bring particulate matter (PM) within permissible limits, after an inspection found emissions standards to be in excess of the existing norms.
The NGT asked the Central Pollution Control Board (CPCB) and Delhi Pollution Control Committee (DPCC) to issue notices to these power plants after a joint report by them, and a representative of the Environment Ministry, found they were violating norms. The Tribunal had previously directed the team to inspect all government-run power and thermal projects in the capital.
As per the report, the monitoring analysis showed that PM levels in the Badarpur coal-based plant’s IIA unit exceeded the standard of 150 mg/Nm3 during some days of the year. At the Rajghat plant, all units exceeded the standard of 150 mg/Nm3 most of the time.
The NGT had earlier directed the team to take samples of ambient air quality around all major power and thermal projects, and suggest remedial measures if emissions were found to be in excess. It also said steps were needed to ensure that emission levels remain within prescribed standards.
