What the agency says

The Environmental Protection Agency (EPA) is proposing to approve a State Implementation Plan (SIP) revision submitted by the Montana Department of Environmental Quality (MDEQ or "the State"), on January 30, 2024, requesting to change the status of gasoline requirements (the "oxygenated fuels" or "oxyfuels" program") in the Missoula, Montana, Carbon Monoxide (CO) limited maintenance plan (LMP) area from an active control measure to a contingency measure. The SIP revision contains a non-interference demonstration under the Clean Air Act (CAA), which concludes that converting the oxygenated gasoline program from a control measure to a contingency measure in the Missoula CO LMP would not interfere with attainment or maintenance of the CO National Ambient Air Quality Standards (NAAQS). The EPA is proposing to approve Montana's SIP submittal pursuant to CAA.
