2060-AW24 202410 The Regulatory Plan and the Unified Agenda of Federal Regulatory and Deregulatory Actions 2060 Office of Air and Radiation OAR 2000 Environmental Protection Agency EPA Emission Guidelines for GHG Emissions From Existing Fossil Fuel-Fired Combustion Turbine EGUs

On May 23, 2023, under section 111 of the CAA, the EPA proposed greenhouse gas (GHG) standards and emission guidelines for new and existing fossil fuel-fired electric generating units (EGUs), and repeal of the Affordable Clean Energy (ACE) Rule. As a part of that action, EPA proposed GHG emission guidelines for a subcategory of existing combustion turbine EGUs. On April 24, 2024, the EPA finalized the other components of that action, but did not finalize the emission guidelines for the existing combustion turbine EGUs. EPA is now undertaking a new rulemaking to establish GHG emission guidelines for existing fossil fuel-fired combustion turbine EGUs under CAA section 111(d).
