Repeal of Greenhouse Gas Emissions Standards for Fossil Fuel-Fired Electric Generating Units
Effective Date: Comments from now until August 7, 2025; virtual public hearing on July 8, 2025;
Summary: A proposed rule by EPA to cut a specific set of standards in regards to emission guidelines that are climate related and carbon captured.
