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 Parish of Pointe Coupee

EPA is granting direct final approval of a revision to the Louisiana State Implementation Plan (SIP) concerning a maintenance plan addressing the 1997 8-hour ozone standard for the parish of Pointe Coupee. On February 28, 2007, the State of Louisiana submitted a SIP revision containing a maintenance plan for the 1997 ozone standard for Pointe Coupee Parish. This plan ensures the continued attainment of the 1997 8-hour ozone National Ambient Air Quality Standard (NAAQS) through the year 2014. 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 this area under the 2008 standard will be addressed in future actions. This maintenance plan meets statutory and regulatory requirements, and is consistent with EPA's guidance.
