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

Phasedown of Hydrofluorocarbons: Excluding Road and Intermodal Container Transport Refrigeration Units From the Hydrofluorocarbon Leak Repair Requirements

The U.S. Environmental Protection Agency (EPA) is proposing an exemption for road and intermodal container transport refrigeration units (TRUs) from the leak repair requirements established under the American Innovation and Manufacturing (AIM) Act. In the final rule "Phasedown of Hydrofluorocarbons: Management of Certain Hydrofluorocarbons and Substitutes Under the American Innovation and Manufacturing Act of 2020," the EPA established, among other provisions, leak repair requirements for refrigerant-containing appliances with a charge size of 15 pounds or more that contain a hydrofluorocarbon (HFC) or certain substitutes for HFCs. The EPA intended to exempt refrigerant-containing road and intermodal container TRUs from the leak repair requirements and is issuing this proposal to clarify the applicability of these requirements. The EPA is not proposing other amendments or taking comment on any other aspects of the 2024 "Phasedown of Hydrofluorocarbons: Management of Certain Hydrofluorocarbons and Substitutes Under the American Innovation and Manufacturing Act of 2020."
