What the agency says

The Environmental Protection Agency (EPA) is proposing to make 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 fine particle (PM<INF>2.5</INF>) National Ambient Air Quality Standards (NAAQS). If we finalize this CDD, certain Clean Air Act (CAA) requirements that apply to the South Coast Air Quality Management District (SCAQMD or "District") 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 proposing to approve 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. We are taking comments on this proposal and plan to follow with a final action.
