요약

EPA is approving revisions to the Louisiana State Implementation Plan (SIP) concerning the 8-hour ozone maintenance plans for the parishes of Beauregard, Grant, and St. Mary. On August 23, 2006, the State of Louisiana submitted separate SIP revisions containing 8-hour ozone maintenance plans for Beauregard and Grant Parishes, and on October 10, 2006, Louisiana submitted an 8-hour ozone maintenance plan for St. Mary Parish. These plans ensure the continued attainment of the 8-hour ozone National Ambient Air Quality Standard (NAAQS) through the year 2014. These maintenance plans meet the statutory and regulatory requirements, and are consistent with EPA's guidance. EPA is approving the revisions pursuant to section 110 of the Federal Clean Air Act (CAA).
