Limited Approval, Limited Disapproval of California Air Plan Revisions; South Coast Air Quality Management District; Refinery Flares

Özet

The Environmental Protection Agency (EPA) is proposing 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. We are proposing action on a local rule to regulate these emission sources under the Clean Air Act (CAA or the Act). We are taking comments on this proposal and plan to follow with a final action.
