On Wednesday, June 11, 2025, the United States Environmental Protection Agency (EPA) issued a proposed rule that would repeal all greenhouse gas (GHG) emissions standards for fossil fuel-fired power plants. The proposed rule was published in the Federal Register on June 17, 2025. Specifically, the proposed rule would repeal the following New Source Performance Standards (NSPSs):
NSPS Subpart TTTTa requires all new and reconstructed stationary combustion turbine EGUs, operating as base load units, to meet emission standards equivalent to installing carbon capture and sequestration technology by January 1, 2032.
The proposed rule states that GHG emissions from fossil fuel-fired power plants do not contribute significantly to dangerous air pollution and that cost-effective GHG control measures, such as carbon capture and sequestration, are not reasonably available.
The EPA is also proposing to repeal the 2024 Final Action, which includes amendments to the National Emission Standard for Hazardous Air Pollutants (NESHAP) Subpart UUUUU, Mercury and Air Toxic Standards (MATS) Rule.
