EPA is finalizing its finding that the Baton Rouge ozone nonattainment area (hereinafter referred to as the Baton Rouge area) did not attain the 1-hour ozone national ambient air quality standard (NAAQS or standard) by November 15, 1999, the attainment date for serious nonattainment areas set forth in the Clean Air Act (CAA or Act). By operation of law, the Baton Rouge area is to be reclassified from a serious to a severe nonattainment area on the effective date of this rule. In addition, EPA is requiring Louisiana to submit State Implementation Plan (SIP) revisions addressing the CAA's pollution control requirements for severe ozone nonattainment areas within 12 months of the effective date of this rule and establishing November 15, 2005, as the date by which the Baton Rouge area must attain the ozone NAAQS. In a Judgment entered on March 7, 2002, the United States District Court for the Middle District of Louisiana, ordered EPA to determine, within 90 days, whether the Baton Rouge area had attained the applicable ozone standard under the CAA, and ordered EPA to promptly thereafter publish the required notice. Louisiana Environmental Action Network (LEAN) v. Whitman, No. 00-879-A. The rulemaking issued today complies with the Court's Judgment. See Supplementary Information regarding a proposed rule published elsewhere in this issue that would affect this final rule.
