2060-AW28 202404 Unified Agenda of Federal Regulatory and Deregulatory Actions 2060 Office of Air and Radiation OAR 2000 Environmental Protection Agency EPA Reclassification of Major Sources as Area Sources Under Section 112 of the Clean Air Act: Requirements for Sources that Reclassify

The final rule, Reclassification of Major Sources as Area Sources Under Section 112 of the Clean Air Act (Major MACT to Area- MM2A final rule), was promulgated on November 19, 2020. (See 85 FR 73854) The EPA proposed the review of the MM2A final rule on September 27, 2023 (See 88 FR 66336) pursuant section (2)(a) of Executive Order 13990. Specifically, EPA proposed requirements that any major source choosing to reclassify to area source status must implement. The EPA is currently in the process of finalizing some aspects of the September 27, 2023, proposal in a separate final rule. This final action will address additional considerations and requirements to further mitigate the potential impacts of the 2020 MM2A final rule, including to address the potential that sources may reclassify and then increase HAP emissions above the levels allowed under the applicable NESHAP.
