🌫️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.

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.
