ACC Ltd Cement’s Barmana plant, in Himachal Pradesh, India, has submitted a supplementary report to the National Green Tribunal (NGT), three months after falling short of environmental issues, stating that the unit is now complying with previously noted failings.
In its latest submission, the NGT said “ACC Ltd was found complying with ambient air quality norms for PM10, SOx, and NOx parameters as prescribed in the National Ambient Air Quality Standards (NAAQS) at six locations monitored between 24-26 March 2025.”
ACC Ltd, which is owned by the Adani Group, has since reported that it had undertaken a series of pollution control measures to address concerns raised in previous inspections. These include installation of mist and rain guns across critical locations, including around the boundary wall and internal roads, and the development of a three-layer plantation near the complainant’s poultry farm and the packing section, with ongoing efforts to green vacant spaces within the premises. It has also deployed interconnected pollution control systems to prevent dust emissions beyond the plant boundary, as well as covering clinker, ash and cement silos with appropriate devices to minimise emissions.
Other measures carried out included the use of rain guns on fly ash bulkers, exit routes to control fugitive dust, installation of a 130m-long, 9m-high MS sheet barrier toward the complainant’s property, with further extension underway as well as the installation of two tyre-washing systems at the raw material and truck exit gates. The plant now has an oil and grease separation unit, and has completed the laying of interlock tiles at the truck exit gate and upgrades of the clinker loading station with sliding doors, installed mist guns and covered cement loading bays with GI sheets and transparent curtains.
