Our most recent Technical Bulletin summarizes guidance EPA is proposing to adopt a flexible, site-specific approach for the steam electric power generating point source category, specifically addressing unmanaged combustion residual leachate (CRL) at existing sources. The EPA believes it will balance environmental protection with economic and technological feasibility. The steam electric power generating industry includes 858 plants, with 63 to 111 potentially discharging unmanaged CRL from unlined or not clean-closed waste management units.
The proposed rule, if finalized, would revise the ELGs for unmanaged combustion residual leachate, or water that leaks from landfills or surface impoundments containing coal combustion residuals. The proposed rule offers a range of regulatory options based on different known technologies and identifies the EPA’s preferred option.
The EPA is accepting written comments on the proposed rule from the public through June 17, 2026. Please see the Federal Register Notice for information on how to submit comments. You may submit comments online at regulations.gov. The Docket Number is EPA-HQ-OW-2009-0819.
