This action is being taken under the Clean Air Act (CAA).

The Environmental Protection Agency (EPA) is determining under the Clean Air Act (CAA) that the Missouri portion of the St. Louis, MO- IL bi-state nonattainment area has achieved clean data for the 2015 8- hour ozone National Ambient Air Quality Standard (NAAQS or standard). This determination of clean data is based upon complete, quality- assured, and certified ambient air monitoring data for the 2023-2025 design value period showing that the Missouri portion of the area achieved attainment of the 2015 ozone NAAQS. The 2023-2025 design value relies upon EPA concurrence on a portion of the exceptional events request as submitted by the Missouri Department of Natural Resources (MoDNR) on November 3, 2025, and concurred on by the EPA on January 27, 2026. The EPA is also approving Missouri's November 3, 2025, clean data determination request. This final clean data determination suspends the obligations of the State of Missouri to submit certain nonattainment area planning requirements for as long as the Missouri portion of the St. Louis area continues to attain the 2015 ozone NAAQS. In a separate action, the EPA is finalizing a similar determination for the Illinois portion of the St. Louis area.

The Environmental Protection Agency (EPA) is determining under the Clean Air Act (CAA) that the Illinois portion of the St. Louis, MO- IL nonattainment area (hereafter also referred to as the "St. Louis area" or "area") has achieved clean data for the 2015 ozone National Ambient Air Quality Standards (NAAQS or standard). This determination is based upon complete, quality-assured, and certified ambient air monitoring data for the 2023-2025 design value period showing that the Illinois portion of the area achieved attainment of the 2015 ozone NAAQS. This determination also relies on the EPA's concurrence of an exceptional events request submitted by the Illinois Environmental Protection Agency (Illinois EPA) on December 18, 2025, and concurred on by the EPA on January 12, 2026. Therefore, the EPA is taking final agency action on Illinois' exceptional events request. In a separate action, the EPA is finalizing a similar determination for the Missouri portion of the St. Louis area. This final determination suspends the requirements for the area to submit attainment demonstrations and associated Reasonably Available Control Measures (RACM), Reasonable Further Progress (RFP) plans, contingency measures for failure to attain or make reasonable progress, and other planning State Implementation Plans (SIPs) related to attainment of the 2015 ozone NAAQS, for as long as the area continues to attain the 2015 ozone NAAQS.

The Environmental Protection Agency (EPA) is taking final action to determine that the Riverside County (Coachella Valley), CA 1997 ozone "Extreme" nonattainment area attained the revoked 1997 ozone national ambient air quality standards (NAAQS) by its June 15, 2025 attainment date. This determination is based on quality-assured and certified ambient air quality monitoring data from 2022 through 2024.

The Environmental Protection Agency (EPA) is finalizing our determination that the Portola nonattainment area in Plumas County, California, attained the 2012 annual fine particulate matter ("PM<INF>2.5</INF>") national ambient air quality standard (NAAQS or "standard") by the December 31, 2025 "Serious" area attainment date. This determination is based on ambient air quality monitoring data from 2023 through 2025. We are also finalizing a clean data determination (CDD) based on the 2023 through 2025 data and our evaluation of preliminary air quality monitoring data from 2026.
