Executive Summary & Key Takeaways

What it means

  • This is a draft notification issued by the Ministry of Environment, Forest and Climate Change, proposing amendments to the Environment (Protection) Rules, 1986.
  • The proposed amendments specifically target emission standards for aluminum plants.
  • The notification invites public feedback on the proposed changes within 60 days of the gazette being made available to the public. The rules will come into force two years after publication in the official gazette.

Key Changes

  • The notification replaces the existing entry for aluminum plants in Schedule-I of the Environment (Protection) Rules, 1986.
  • New emission standards are introduced for various processes within aluminum plants, including alumina refineries and aluminum smelters.
  • For alumina refineries, particulate matter limits are set at 150 mg/Nm3 for raw material handling and 100 mg/Nm3 for calcination. Carbon monoxide limit is set at 1% maximum.
  • For aluminum smelters, particulate matter limits are set at 100 mg/Nm3 for green anode plants and 50 mg/Nm3 for anode baking plants.
  • Total fluoride emission limit is set at 0.3 kg/MT of aluminum for anode baking plants and 0.8 kg/MT of aluminum for electrolytic pot rooms. Aluminum Fluoride (AlF3) consumption is capped at 20 kg/ton of aluminum.
  • For electrolytic pot rooms, different particulate matter limits are specified for old (50 mg/Nm3) and new units (30 mg/Nm3), with the cut-off date being 31st December 2010.
  • Particulate matter limit for casting furnaces (oil furnace) is set at 150 mg/Nm3.
  • Standards for forage fluoride are introduced, with limits of 40 ppm (twelve-month average), 60 ppm (two-month average) and 80 ppm (one-month average of two samples taken 12 days apart).
  • The notification mandates the installation of Continuous Emission Monitoring Systems (CEMS) for monitoring particulate matter and sulfur dioxide emissions.
  • The use of fuels with more than 1% sulfur, such as LDO and LSHS, is restricted in calcination plants, anode baking plants, and oil-fired casting furnaces. Cleaner fuels are encouraged.
  • The stack height for the processes shall be as proposed in the EIA study or as prescribed by the State Pollution Control Board, whichever is higher.
  • The previous CREP 2003 recommendations for total fluoride consumption are replaced by the new standard of 20 kg/ton of Al for AlF3 consumption.

Impact Analysis

Aluminum Industry

  • The new limits on AlF3 consumption will require changes in production processes and possibly increased costs.

Government

  • The government will need to ensure the effective implementation of the new rules and may need to provide support to the industry to meet the new standards.

Environment

  • The continuous monitoring of emissions will help in better tracking and control of pollution.

Public

  • The implementation of the new standards is expected to lead to a healthier environment.

Action Items

  • Stakeholders should review the draft notification and submit feedback to the Ministry of Environment, Forest and Climate Change within the stipulated timeframe.
