On November 20, with no fanfare at all, not even a press release, U.S. Environmental Protection Agency (EPA) issued its Draft Guidance: Applying the Supreme Court’s County of Maui v. Hawaii Wildlife Fund Decision in the Clean Water Act Section 402 National Pollutant Discharge Elimination System Permit Program to Discharges Through Groundwater. This draft guidance is the agency’s second effort to guide implementation of the U.S. Supreme Court’s 2020 decision, which extends applicability of the National Pollutant Discharge Elimination System (NPDES) permitting program to include the “functional equivalent” of point source discharges of pollutants to waters of the U.S.Continue reading EPA’s New Proposed Maui Guidance: Underwhelming and Sneaky

EPA Signals More Stringent Regulation for Steam Electric Power Generators
EPA announced yesterday its intent to revise some portions of the 2020 Steam Electric Effluent Limitation Guideline Reconsideration Rule (2020 ELG Rule). EPA’s press release and the pre-publication version of its Federal Register notice sent a clear message that the agency is aiming at membrane technology to control flue gas desulfurization (FGD) wastewater discharges from coal-fired power plants. The notice also states that the agency will reconsider the technology selected for bottom ash transport, and it may revise or eliminate the subcategories created by the 2020 ELG Rule for high-flow facilities, low-utilization facilities, and for facilities that commit to retire or repower coal-fired units by 2028.
