## Abstract

Pursuant to the Federal Clean Air Act (CAA or the Act), the Environmental Protection Agency (EPA) is approving a Louisiana State Implementation Plan (SIP) revision revising the 2008 8-hour ozone National Ambient Air Quality Standard (NAAQS) maintenance plan for the five-parish Baton Rouge area. The revised maintenance plan allows for relaxation of the Federal Reid Vapor Pressure (RVP) requirements in the Baton Rouge area. EPA has determined that relaxation of the RVP requirement would not interfere with attainment or maintenance of the NAAQS or with any other CAA requirement.
