Providing for congressional disapproval under chapter 8 of title 5, United States Code, of the rule submitted by the Environmental Protection Agency relating to "Review of Final Rule Reclassification of Major Sources as Area Sources Under Section 112 of the Clean Air Act".

HJRES 204 is a congressional disapproval resolution targeting an EPA rule that would have reclassified certain large pollution sources (like industrial facilities) as smaller, less-regulated "area sources" under the Clean Air Act. If passed, this resolution would block the EPA's September 10, 2024, rule (published in the Federal Register) from taking effect, preventing the regulatory change. The resolution directly affects the EPA's authority to implement this specific reclassification, which would have altered how certain facilities are regulated under Section 112 of the Clean Air Act. It does not create new policy but halts an existing EPA rule through a procedural congressional action.
