Last week, the U.S. Environmental Protection Agency (“EPA”) published in the Federal Register a set of four final rules targeting pollution and greenhouse gas (“GHG”) emissions from nuclear and “fossil fuel”-fired power plants (e.g., coal, oil and natural gas). These new rules, which EPA asserts are statutorily authorized under the Clean Air Act, Clean Water Act, and Resource Conservation and Recovery Act, will: (i) revise emissions guidelines for new and existing fossil fuel-fired electric generating units (“EGUs”); (ii) set technology-based emissions standards for mercury and other hazardous air pollutants emitted by units with a capacity of more than 25 megawatts; (iii) revise discharge limits for flue gas desulfurization (“FGD”) wastewater, bottom ash transport water (“BATW”), combustion residual leachate (“CRL”) and legacy wastewater; and (iv) adjust regulations for inactive coal combustion residual (“CCR”) surface impoundments at inactive electric utilities. The rules are slated to become effective later in 2024. Given the ramifications of these new rules for the power sector, however, certain states and industry groups are already challenging some of these final rules, and the final efficacy of these rules remains uncertain. This Alert will discuss the major requirements of each of these new rules along with expected legal challenges, building upon our prior Alert on this topic. (Continue Reading)
