The Environmental Protection Agency (EPA) is taking final action to approve revisions to the San Joaquin Valley Unified Air Pollution Control District (SJVUAPCD) and South Coast Air Quality Management District (SCAQMD) portions of the California State Implementation Plan (SIP). These revisions concern emissions of volatile organic compounds (VOCs) and oxides of nitrogen (NO<INF>X</INF>) from flares. We are approving these local rules to regulate these emission sources under the Clean Air Act (CAA or the Act).
