What the agency says

Under the Clean Air Act (CAA), EPA may approve State or local rules or programs to be implemented and enforced in place of certain otherwise applicable Federal rules, emissions standards, or requirements. On October 6, 2025, the Missouri Department of Natural Resources (MoDNR), on behalf of the State of Missouri, requested delegation of a partial CAA Risk Management Program (RMP) for agricultural anhydrous ammonia facilities. The request was supplemented by MoDNR on October 9, 2025, and on October 27, 2025. The EPA has determined that MoDNR's request meets CAA requirements for delegation of a partial program, and the EPA is proposing to approve the request.
