This format revision will primarily affect the "Identification of plan--in part" sections, as well as the format of the SIP materials that will be available for public inspection at the EPA Regional Office and the National Archives and Records Administration (NARA). This action, which only relates to local ordinances and certain local and regional California air district rules, is the second of a series of actions intended to change the format for the entire California SIP.
Learn More🌫️EPA Proposes Rule for Mariposa County Air Quality Standards Compliance
The Environmental Protection Agency (EPA) is proposing to determine that the Mariposa County nonattainment area in California ("Mariposa area"), classified as "Moderate" for the 2015 ozone national ambient air quality standards (NAAQS or "standard"), attained the 2015 ozone NAAQS by the August 3, 2024 attainment date. Our proposed determination of attainment is based upon the exclusion of exceedances of the 2015 ozone NAAQS that occurred on multiple days in 2021 and 2022, because the exceedances are due to exceptional events. This action, if finalized as proposed, will fulfill the EPA's statutory obligation to determine whether the Mariposa area attained the NAAQS by the August 3, 2024 attainment date.
Learn More🌫️Clean Data Determination for Los Angeles-South Coast Air Basin
The Environmental Protection Agency (EPA) is making a clean data determination (CDD) for the Los Angeles-South Coast Air Basin ("South Coast") air quality planning area in California based on our determination that the area is attaining the 2006 24-hour fine particulate matter (PM<INF>2.5</INF>) national ambient air quality standards (NAAQS). As a result of this CDD, certain Clean Air Act (CAA) requirements that have applied to California will be suspended for so long as the area continues to meet the 2006 24-hour PM<INF>2.5</INF> NAAQS. The EPA is also approving a revision to California's state implementation plan (SIP) consisting of the 2018 base year emissions inventory for the South Coast PM<INF>2.5</INF> nonattainment area, submitted by the California Air Resources Board (CARB) on December 29, 2020.
