## Abstract

The Environmental Protection Agency (EPA) is approving a State Implementation Plan (SIP) revision submitted by the Wisconsin Department of Natural Resources (WDNR) on November 14, 2014, to address emission inventory requirements for the Sheboygan nonattainment area (Sheboygan area) and the Wisconsin portion (Kenosha area) of the Chicago-Naperville, Illinois-Indiana-Wisconsin (Chicago-Naperville, IL- IN-WI) nonattainment area under the 2008 ozone National Ambient Air Quality Standard (NAAQS or standard). The Clean Air Act (CAA) requires emission inventories for all ozone nonattainment areas. The emission inventories contained in Wisconsin's November 14, 2014, submission meet this CAA requirement.
