New Delhi The Municipal Corporation of Delhi (MCD) issued 28 challans and imposed a fine of ₹3.8 lakh on the Delhi Metro Rail Corporation (DMRC) on Friday, following repeated violations of dust-control and pollution-mitigation rules at several construction sites.

The MCD said that its south and central zones found uncovered construction materials, inadequate dust-suppression systems, missing barricades, and poor housekeeping at multiple DMRC sites.

Of the 28 challans, 24 were issued in accordance with the National Green Tribunal’s guidelines and others for violating the Solid Waste Management Rules, 2016. Delhi’s air remained in the ‘very poor’ category on Friday.

The south zone alone issued 17 challans worth ₹1.8 lakh during an inspection of MB Road, with fines ranging from ₹5,000 to ₹50,000. Under NGT directions, no agency or contractor can store construction material on metalled roads, spill debris beyond work sites, or leave waste uncovered. Dumping that blocks drains or exposes material without proper shielding is also prohibited, an MCD official said.
