## Abstract

The Environmental Protection Agency (EPA) is taking final action to approve a revision to the South Coast Air Quality Management District (SCAQMD or "District") portion of the California State Implementation Plan (SIP). We are also determining that the submitted SIP revision fulfills the District's and the State's commitment to adopt and submit a specific enforceable contingency measure to address Clean Air Act (CAA or "Act") requirements for the 2006 24-hour and 2012 annual national ambient air quality standards (NAAQS) for fine particulate matter (PM<INF>2.5</INF>) in the South Coast air basin.
