Biden administration aims to clean up power sector with revamped rules

WASHINGTON — The Biden administration on Thursday announced it has finalized rules targeting carbon, air and water pollution from power plants that it says could cut over 1 billion metric tons from carbon emissions by 2047 even as demand for electricity grows. The Environmental Protection Agency tightened a proposal to slash carbon emissions from existing coal and new gas plants, and updated and finalized long-standing rules to reduce mercury and toxic air pollutants and clean up wastewater and coal ash discharge.
