Nov 2 Comment deadline –: EPA – Proposed Repeal of Regulations for Power Plant Greenhouse Gas Emissions Under CAA
Nov 2, 2026: EPA power plant greenhouse gas repeal
This is the Rescission of the Greenhouse Gas Findings for Fossil Fuel-Fired Power Plants and Repeal of Regulations for Power Plant Greenhouse Gas Emissions Under Clean Air Act Section 111, with the comment period ending Nov 2, 2026 at 11:59 PM EST.
It goes further than the earlier rule: EPA is proposing that Congress never gave it authority under that section to regulate power plant emissions to address global climate change.
Members of the public can follow the rulemaking through the regulations.gov docket EPA lists, numbered EPA-HQ-OAR-2025-0124, and EPA says it will post hearing details there soon.

Monday, Nov 2, 2026, 9:30–9:59 pm MT — Deadline to comment against EPA’s repeal of all power plant climate pollution limits
Summary: EPA proposes that Clean Air Act section 111 does not authorize it to regulate emissions from power plants in response to global climate change concerns, which would require rescinding the Administrator’s contrary findings and determinations in 2015 and repealing all associated 2015 and 2024 GHG standards for coal and gas plants. This follows the February 2026 repeal of the Endangerment Finding. Comment on the authority question itself, since EPA is not reopening the concurrently published final rule. EPA numbers its questions, and asks commenters to include the corresponding identifier (e.g., “C-1”) when submitting comments relevant to that solicitation.

Ready-made alert: NRDC has a comment form at https://action.nrdc.org/letter/5269-PowerPlantReg-091426. It notes that over 26,000 NRDC supporters already spoke out against rolling back carbon standards for power plants. The other groups on your list (EDF, Earthjustice, UCS, CBD, Sierra Club) co-filed on earlier rounds, but I didn’t find their action pages for this round yet.
