Approval and Promulgation of Implementation Plans; Louisiana; Baton Rouge Nonattainment Area; Ozone; 1-Hour Ozone Attainment Demonstration; Attainment Date Extension, and Withdrawal of Nonattainment Determination and Reclassification

Pursuant to the Clean Air Act (Act), EPA is approving the Louisiana 1-hour ozone attainment demonstration State Implementation Plan (SIP) for the Baton Rouge serious ozone nonattainment area. In conjunction with its approval of the attainment demonstration, EPA is: approving Louisiana's transport demonstration and extending the ozone attainment date for the Baton Rouge ozone nonattainment area to November 15, 2005, while retaining the area's current classification as a serious ozone nonattainment area; withdrawing EPA's June 24, 2002, rulemaking determining nonattainment and reclassification of the Baton Rouge ozone nonattainment area; finding that the Baton Rouge ozone nonattainment area meets the reasonably available control measures (RACM) requirements of the Act; approving the State's enforceable commitment to perform a mid-course review and submit a SIP revision to EPA by May 1, 2004; approving the motor vehicle emissions budget (MVEB) and an enforceable commitment to submit revised budgets using MOBILE6; and approving an enforceable transportation control measure (TCM). This action also approves SIP submittals relating to corrections to the 1990 Base Year Emissions Inventory, the 9% Rate-of-Progress Plan (ROPP), and the 15% ROPP.
