Senior Sena leader Subhash Desai said the conversion of the 500-MW oil and gas fired unit 6 to coal-run will compound the air pollution problem in Ghatkopar, Chembur, Deonar and Mankhurd.u00a0

"We told their management today that the unit 6 be converted and should run on oil/gas. Similarly, we asked them to close down units 3 and 5 and convert them to gas fired ones or use any other environment-friendly solution," Desai said.
