What the agency says

The Environmental Protection Agency (EPA) is taking final action to approve revisions to the Missouri State Implementation Plan (SIP) received on March 19, 2025, that contain updates to the construction permit requirement regulations for stationary and portable air sources in Missouri that help ensure ambient air quality standards are met. The revisions to this rule include updating the fees for facilities applying for and receiving construction permits for air pollution sources; removing a subsection from the state rule that was never approved in the SIP; and making administrative wording changes. The EPA is correcting the state effective date in table C from the original proposal. These revisions do not interfere with the State's ability to attain or maintain the National Ambient Air Quality Standards (NAAQS), reasonable further progress (RFP) or other Clean Air Act (CAA) requirements. The EPA's final approval of this rule revision is being done in accordance with the requirements of the CAA.
