## Abstract

The Environmental Protection Agency (EPA) is approving a revision to the Arkansas State Implementation Plan (SIP) submitted to meet the Clean Air Act (CAA) emissions inventory (EI) requirement for the Crittenden County ozone nonattainment area. EPA is approving the SIP revision because it satisfies the CAA EI requirement for Crittenden County under the 2008 8-hour ozone National Ambient Air Quality Standards (NAAQS). The inventory includes emissions data for Nitrogen Oxides (NO<INF>X</INF>) and Volatile Organic Compounds (VOCs). EPA is approving the revisions pursuant to section 110 and part D of the CAA and EPA's regulations.
