Steps
Search regulations.gov docket EPA-HQ-OAR-2024-0089, EPA's Clean Air Act Section 111(b) periodic review of the wood heater NSPS
Cite the governing suit correctly as State of New York v. Regan, No. 1:23-cv-2767 (D.D.C.), filed September 21, 2023 by ten states -- New York, Alaska, Illinois, Maryland, Massachusetts, Minnesota, New Jersey, Oregon, Vermont, and Washington -- plus the Puget Sound Clean Air Agency; Sierra Club is NOT a plaintiff in this action
Confirm the two consent-decree deadlines: Subpart AAA (room heaters) review due December 15, 2026; Subpart QQQQ (hydronic heaters/furnaces) review due December 15, 2027
Check epa.gov/stationary-sources-air-pollution/new-source-performance-standards-residential-wood-heaters for any newly published proposed rule
Check federalregister.gov for a Subpart AAA/QQQQ NPRM before citing "no proposal yet" as current
Known gotchas
Do not attribute this suit to the Sierra Club -- the plaintiffs are ten states plus the Puget Sound Clean Air Agency; Sierra Club's 2022 EPA rulemaking petition is a separate, unrelated proceeding, and conflating the two misstates who holds enforcement leverage over the consent decree
A consent decree sets a deadline to act (propose a revision or issue a no-revision determination) -- it does not guarantee tighter standards will result
As of this research no final or proposed rule revising Subparts AAA/QQQQ had published; status can move quickly close to the December 15, 2026 deadline, so re-check federalregister.gov same-day before reporting
