Air Plan Limited Approval and Limited Disapproval; California; South Coast Air Quality Management District; Refinery Flares

Riepilogo

The Environmental Protection Agency (EPA) is finalizing a limited approval and limited disapproval of revisions to the South Coast Air Quality Management District (SCAQMD) portion of the California State Implementation Plan (SIP). These revisions concern emissions of volatile organic compounds (VOCs) and oxides of nitrogen (NO X ) from refinery flares. Under the authority of the Clean Air Act (CAA or the Act), this action simultaneously approves a local rule that regulates these emission sources and directs California to correct rule deficiencies.
