Interim Final Determination To Defer Sanctions; California; Los Angeles-South Coast Air Basin

The Environmental Protection Agency (EPA) is making an interim final determination to defer the imposition of offset and highway sanctions in the Los Angeles-South Coast air basin (``South Coast'') based on a proposed approval of revisions to the South Coast portion of the California State Implementation Plan (SIP) published elsewhere in this Federal Register. The revisions concern Clean Air Act (CAA) reasonably available control measures/reasonably available control technology (RACM/RACT) and reasonable further progress (RFP) requirements for the 2006 24-hour fine particulate matter (PM2.5) national ambient air quality standards (NAAQS) in the South Coast.
