Air Plan Approval; Maryland; Clean Data Determination for the Baltimore, MD Nonattainment Area for the 2015 Ozone National Ambient Air Quality Standards

The Environmental Protection Agency (EPA) is determining that the Baltimore, Maryland (MD) nonattainment area (the Baltimore Area or the Area) has clean data for the 2015 8-hour ozone national ambient air quality standard (NAAQS or standard). This determination is based upon quality-assured, quality-controlled, and certified ambient air monitoring data for the 2022-2024 design value (DV) period showing that the Baltimore Area attained the 2015 ozone NAAQS, with the exclusion of certain monitoring data impacted by exceptional events. The EPA is taking final agency action on portions of three exceptional event (EE) requests submitted by the Maryland Department of the Environment (MDE) on February 2, 2024, on behalf of MD, and concurred on by the EPA on November 12, 2025. As a result of the clean data determination (CDD), under the EPA's Clean Data Policy, the EPA is suspending the requirements for the Baltimore Area to submit attainment demonstrations and associated Reasonably Available Control Measures (RACM), Reasonable Further Progress (RFP) plans, contingency measures, and other planning SIPs related to attainment of the 2015 ozone NAAQS, for as long as the Baltimore Area continu

Air Plan Approval; Michigan; Determination of Attainment by the Attainment Date for the 2015 Ozone Standards

The Environmental Protection Agency (EPA) is proposing to determine under the Clean Air Act (CAA) that the Detroit, Michigan nonattainment area ("Detroit area" or "area") attained the 2015 ozone National Ambient Air Quality Standards (NAAQS) by the applicable attainment date. This determination relies on the EPA's concurrence on an exceptional events request submitted by the Michigan Department of Environment, Great Lakes, and Energy (EGLE) on February 19, 2026, and concurred on by the EPA on March 24, 2026. Therefore, the EPA is proposing to take final agency action on Michigan's exceptional events request. This action, if finalized, will fulfill the EPA's statutory obligation to determine whether the Detroit area attained the 2015 ozone NAAQS by the Moderate attainment date of August 3, 2024.
