Approval and Promulgation of Implementation Plans; State of Missouri

EPA is taking final action to approve a set of volatile organic compound (VOC) rules for the St. Louis, Missouri, nonattainment area. These rules are intended to satisfy the reasonably available control technology (RACT) requirements of section 182(b)(2) of the Clean Air Act (Act) Amendments of 1990. The VOC reductions achieved by the implementation of these rules will be accounted for in the 15% Rate-of-Progress Plan (ROPP) and the attainment demonstration for the St. Louis nonattainment area as required in section 182(b)(1)(A) of the Act. EPA is addressing the reductions as part of the 15% ROPP and the attainment demonstration in separate rulemaking actions.
