EPA Repeals 2024 Power Plant Carbon Rules and Proposes Ending GHG Regulation Under Section 111
jw.comEPA has finalized a repeal of most of the 2024 Carbon Pollution Standards for power plants, including the 90 percent carbon capture mandate for existing coal units and the CCS standards for new baseload gas turbines. The agency also proposed a supplemental rule that would end greenhouse gas regulation of power plants under Clean Air Act Section 111 entirely, arguing the statute does not authorize climate-based limits. The final rule removes the compliance deadlines that were driving coal retirements and complicating new gas construction. Phase 1 efficiency standards for new turbines remain for now, but the supplemental proposal would repeal those too. EPA estimates the repeal saves the power sector $95 to $160 billion through 2047, and the changes affect PSD permitting by removing the GHG BACT floor. The supplemental proposal has a 45-day public comment period and a virtual hearing. Litigation in the D.C. Circuit is expected. Anyone with retirement plans, new gas projects, or permitting exposure should review the docket and decide whether to comment.
