The Environmental Protection Agency is proposing actions to address greenhouse gas emissions from fossil fuel-fired electric generating units. The proposal would revise new source performance standards, with specific criteria for new, existing, and modified plants. The proposal would also repeal the Affordable Clean Energy Rule. A virtual public hearing will be held 21 days following publication in the Federal Register. Comments due 60 days after publication date.
In this notice, the Environmental Protection Agency (EPA) is proposing five separate actions under section 111 of the Clean Air Act (CAA) addressing greenhouse gas (GHG) emissions from fossil fuel-fired electric generating units (EGUs). The EPA is proposing revised new source performance standards (NSPS), first for GHG emissions from new fossil fuel-fired stationary combustion turbine EGUs and second for GHG emissions from fossil fuelfired steam generating units that undertake a large modification, based upon the 8-year review required by the CAA. Third, the EPA is proposing emission guidelines for GHG emissions from existing fossil fuel-fired steam generating EGUs, which include both coal-fired and oil/gas-fired steam generating EGUs. Fourth, the EPA is proposing emission guidelines for GHG emissions from the largest, most frequently operated existing stationary combustion turbines and is soliciting comment on approaches for emission guidelines for GHG emissions for the remainder 2 This document is a prepublication version, signed by EPA Administrator, Michael S.

Finally, the EPA is proposing to repeal the Affordable Clean Energy (ACE) Rule.
