Approval and Promulgation of Implementation Plans; Louisiana; Baton Rouge Nonattainment Area; Base Year Emissions Inventory for the 2008 8-Hour Ozone Standard

The Environmental Protection Agency (EPA) is proposing to approve a revision to the State Implementation Plan (SIP) submitted by the Louisiana Department of Environmental Quality (LDEQ) to address the emissions inventory (EI) requirement for the Baton Rouge ozone nonattainment area (BRNA) for the 2008 8-hour ozone National Ambient Air Quality Standards (NAAQS). The Clean Air Act (CAA) requires an EI for all ozone nonattainment areas. The inventory includes emission data for Nitrogen Oxides (NOX) and Volatile Organic Compounds (VOCs). EPA is approving the revisions pursuant to section 110 and part D of the CAA and EPA's regulations.
