Following a meeting with industrialists from National Capital Region (NCR), including Noida and Ghaziabad, the Commission for Air Quality Management (CAQM), the agency tasked with enforcing the revamped Graded Response Action Plan (Grap) to combat air pollution in Delhi-NCR, has issued a revised directions allowing the use of diesel generators (DG sets) for two hours daily only for industrial and commercial purposes.
CAQM has also recommended the monitoring of stack emissions (essentially, gases released into the air from boiler stacks, chimneys or DG sets after the incineration process) during the period of Grap, which comes into effect from October 1, as the pollution levels are expected to start increasing from autumn.
To be sure, the commission on November 16, 2021, banned the use of DG sets except for emergency purposes, during the period when Grap is in force. On February 8, 2022, it said DG sets should be equipped with retrofitted emission controlled devices (RECD) and be converted to run on duel fuel mode (gas and diesel) with piped natural gas (PNG) as the main fuel.
