On June 11, the EPA proposed two Clean Air Act (CAA) rules that would affect fossil-fuel fired electric generating units (EGUs). One rule would repeal greenhouse gas (GHG) standards under Section 111 and the second would repeal the 2024 EPA amendments to the mercury and air toxics (MATS) standards.
