On October 13, 2006 and December 19, 2006, the State of Louisiana submitted maintenance plans for Lafayette and Lafourche Parishes, respectively, which ensure 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).
