## Abstract
The EPA is approving revisions to the Louisiana State Implementation Plan (SIP). This rulemaking covers two separate actions. First, we are approving revisions to the Louisiana Nitrogen Oxides (NOX) rules in the Baton Rouge (BR) 1-hour ozone nonattainment area (BR area) and its Region of Influence as submitted to us by the State on February 27, 2002 (the February 27, 2002, SIP revision). In this document, we will refer to this revision as Action Number 1. The revisions concern Reasonably Available Control Technology (RACT) for point sources of NOX in the BR area and its Region of Influence. Second, we are approving revisions to the Louisiana NOX rules for lean burn engines within the BR ozone nonattainment area as submitted to us on July 25, 2002 (the July 25, 2002, SIP revision). In this document, we will refer to this revision as Action Number 2. The February 27, and July 25, 2002, SIP revisions will contribute to attainment of the 1-hour ozone National Ambient Air Quality Standard (NAAQS) in the BR area. The EPA is finalizing approval of these 2 SIP revisions to regulate emissions of NOX as meeting the requirements of the Federal Clean Air Act (the Act). The EPA is making these 2 SIP revisions effective immediately. See section 2 of this document for more information.
