Mahagenco: Stricter norms to contain power plant pollution
In order to reduce air pollution by mushrooming coal-fired thermal power generation units, union ministry of environment and forests (MoEF) has formulated stricter pollution control norms for these units. The Environment (Protection) Rules, 1986, have been amended for this purpose. If these norms are followed by Mahagenco, Nagpurians will get some relief from air pollution caused by Koradi and Khaparkheda power plants. The strictest norms are for units that will be installed from January 2017 onwards.
The new norms have put restriction on water consumption by thermal units. Till now the water norms under these rules were related to pH value, temperature and level of various substances in the water used in cooling tower and boiler and that in the ash pond effluent.
The norms state that all units using a once through cooling system will have to install a cooling tower and restrict water consumption to 3.5 cubic metre per unit. This has to be done within the coming two years. The units having cooling tower will also have to adhere to water consumption restriction. New plants installed after January 1, 2017 will have to restrict water consumption to 2.5 cubic metre per unit and achieve zero waste water discharge.
