## Abstract

The Environmental Protection Agency (EPA) is taking final action to approve a State Implementation Plan (SIP) revision submitted by the State of Missouri to EPA in a letter dated May 4, 2012. The purpose of the SIP revision is to amend Missouri's regulation for the control of Volatile Organic Compounds (VOC) and meet the requirement to adopt reasonably available control technology (RACT) for sources covered by EPA's Control Technique Guidelines (CTG) for Industrial Cleaning Solvents. We are taking final action to approve this revision because it satisfies the applicable requirements of the Clean Air Act (CAA) with respect to RACT for the Missouri portion of the St. Louis Metropolitan 1997 8-hour ozone nonattainment area.
