On September 14, the U.S. Environmental Protection Agency finalized a rule repealing most of the 2024 Carbon Pollution Standards for power plants. EPA said the final rule strikes standards the agency determined exceed its authority under the Clean Air Act, pointing to control technology requirements it argues have not been adequately demonstrated. The agency projects the repeal will save $310 billion in compliance costs.
EPA has also proposed a supplemental rule rescinding all remaining greenhouse gas (GHG) emissions requirements for the power sector, contending Section 111 does not give the agency authority to regulate power plant emissions on the basis of climate impact. EPA estimates the proposed rule, if finalized, would yield an additional $370 million in direct compliance savings. EPA will hold a public hearing 15 days after the proposal's publication in the Federal Register, followed by a 45-day public comment period.
Both rules (final and proposed) are available on EPA’s website at https://www.epa.gov/stationary-sources-air-pollution/greenhouse-gas-standards-and-guidelines-fossil-fuel-fired-power.
