Gurugram, Jan. 4 -- The Commission for Air Quality Management carried out a large-scale enforcement drive in Nuh district, Haryana, on Friday, inspecting 105 industrial units and construction and demolition sites under Operation Clean Air, officials said. Inspections occurred while actions up to Stage 3 of the Graded Response Action Plan were in force. Ten flying squad teams from the commission operated with the district administration, Haryana State Pollution Control Board, and local police, officials said. Of the 105 inspections, five were C&D sites and 100 were industrial units, including 86 stone crushers, five tyre pyrolysis plants, five ready-mix concrete plants, three hot-mix plants and one screening and washing unit, officials added. The commission said almost all units were found non-operational, closed or dismantled, complying with Grap Stage 3. However, violations were detected in three units related to the use of diesel generator (DG) sets, contravening commission direction No. 76. The CAQM said strong and visible enforcement is essential to curb violations at the source and provide relief to residents living near industrial clusters. "These violations have been taken seriously, as DG sets are a significant source of particulate and gaseous emissions during winter months," the commission said, adding such non-compliance undermines Grap's objective. "These inspections are aimed at ensuring that industries and C&D sites strictly adhere to prescribed norms."...
