    The Environmental Protection Agency (EPA) is proposing a partial approval and disapproval of changes to South Carolina's State Implementation Plan (SIP) concerning minor source permit program requirements. Specifically, the EPA plans to approve some administrative updates and certain procedural changes, but proposes to disapprove sections where the changes do not meet federal standards for public notice and participation as required by the Clean Air Act. These decisions impact how South Carolina regulates air pollution from smaller industrial sources, ensuring they comply with national air quality standards. The public is invited to comment on the proposal by February 20, 2025.
