Core Purpose

This notification introduces the Environment (Protection) Fifth Amendment Rules, 2025, to amend Schedule-I of the Environment (Protection) Rules, 1986, by substituting the entries for serial number 36 relating to 'ALUMINIUM PLANTS'.

Detailed Summary

The Ministry of Environment, Forest and Climate Change, on July 21, 2025, issued G.S.R. 482(E), publishing the Environment (Protection) Fifth Amendment Rules, 2025. These rules, made by the Central Government under sections 6 and 25 of the Environment (Protection) Act, 1986 (29 of 1986), will come into force two years from their publication in the Official Gazette. This amendment substitutes serial number 36 and its related entries in Schedule-I of the Environment (Protection) Rules, 1986, concerning 'ALUMINIUM PLANTS'. The new standards specify emission limits for Particulate Matter and Carbon Monoxide for Alumina Refinery sub-processes (Raw Material Handling: 150 mg/Nm³, Calcination Plant: 100 mg/Nm³ PM, 1% Max CO) and Aluminium Smelter sub-processes (Green Anode Plant: 100 mg/Nm³ PM, Anode Baking Plant: 50 mg/Nm³ PM, 0.3 kg/MT of Al Max Total Fluoride (F), Electrolytic Pot Room: 50 mg/Nm³ PM for old units (prior to 31.12.2010) and 30 mg/Nm³ PM for new units (on/after 01.01.2011), 0.8 kg/ton of Al Max Total Fluoride (F), Casting Furnace (oil furnace): 150 mg/Nm³ PM). Additionally, standards for Forage Fluoride (dry weight basis) are set at 40 ppm for a twelve-month average, 60 ppm for a two-month average, and 80 ppm for a one-month average (of two samples 12 days apart). The rules also mandate stack heights as per Environmental Clearance or State Pollution Control Board/Pollution Control Committee consent, use of fuels with not more than 1% sulphur in specific processes, installation of continuous emission monitoring systems for Particulate Matter and Sulphur dioxide, and limit Aluminium Fluoride (AlF3) consumption to 20 kilograms per ton of aluminium produced from the notification date. Process effluent norms are to be as per State Pollution Control Board/Pollution Control Committee consent, and industrial boiler standards under the Environment Protection Rules, 1986, apply to Aluminium Refinery and Smelter boilers. These rules follow consideration of objections and suggestions received after the draft Environment (Protection) Amendment Rules, 2024, were published via G.S.R. 680(E) on November 1, 2024.
