To nullify the final rule issued by the Environmental Protection Agency relating to "New Source Performance Standards for Greenhouse Gas Emissions From New, Modified, and Reconstructed Fossil Fuel-Fired Electric Generating Units; Emission Guidelines for Greenhouse Gas Emissions From Existing Fossil Fuel-Fired Electric Generating Units; and Repeal of the Affordable Clean Energy Rule".

HR 1651 would nullify a specific Environmental Protection Agency (EPA) rule finalized on May 9, 2024. This rule established emissions standards for greenhouse gases from new, modified, and reconstructed fossil fuel power plants, set guidelines for existing plants, and repealed the previous "Affordable Clean Energy Rule." The bill would make this EPA rule unenforceable, directly affecting fossil fuel power plants by removing these federal emissions requirements. It does not create new regulations but cancels an existing EPA rule.
