Approval and Promulgation of Air Quality Implementation Plans; Louisiana; Approval of Section 110(a)(1) Maintenance Plan for the 1997 8-Hour Ozone Standard for the New Orleans Ozone Maintenance Area

Riepilogo

EPA is approving this revision to the Louisiana State Implementation Plan (SIP) concerning the maintenance plan addressing the 1997 8-hour ozone standard for the New Orleans Ozone Maintenance Area. On June 29, 2007, the State of Louisiana submitted a maintenance plan for the New Orleans Ozone Maintenance Area, which includes the parishes of Jefferson, Orleans, St. Bernard and St. Charles, which ensures continued attainment of the 1997 8-hour ozone National Ambient Air Quality Standard (NAAQS) through the year 2014. This maintenance plan meets the statutory and regulatory requirements, and is consistent with EPA's guidance. EPA is approving the revision pursuant to section 110 of the Federal Clean Air Act (CAA). On March 12, 2008, EPA issued a revised ozone standard. Today's action, however, is being taken to address requirements under the 1997 ozone standard. Requirements for the New Orleans area under the 2008 standard will be addressed in future actions.
