2060-AW28 202504 Unified Agenda of Federal Regulatory and Deregulatory Actions 2060 Office of Air and Radiation OAR 2000 Environmental Protection Agency EPA Congressional Review Act Revocation of 2024 Review of Final Rule Reclassification of Major Sources as Area Sources Under Section 112 of the Clean Air Act

On June 20, 2025, President Donald J. Trump signed into law S.J. Res. 31, a joint resolution under the Congressional Review Act (CRA) disapproving the EPA’s 2024 rule amending the 2020 Reclassification of Major Sources as Area Sources Under Section 112 of the Clean Air Act (CAA) (also known as MM2A”). The 2024 MM2A Rule amended the 2020 MM2A Rule by requiring sources of persistent and bioaccumulative hazardous air pollutants (HAP) listed in CAA section 112(c)(6) to continue to comply with major source emission standards under CAA section 112(d)(2) or standards under CAA section 112(d)(4) even if the sources reclassify as area sources. By the terms of the CRA, the signing into law of the CRA joint resolution of disapproval means that the 2024 MM2A Rule is treated as if it had never taken effect. This action will remove the 2024 MM2A Rule amendments from the Code of Federal Regulations, so that the regulation as promulgated by the 2020 MM2A Rule will be in effect.
