The Environmental Protection Agency (EPA) is proposing to approve elements of a State Implementation Plan (SIP) revision submission from the State of Missouri addressing the applicable requirements of section 110 of the Clean Air Act (CAA) for the 2015 Ozone (O<INF>3</INF>) National Ambient Air Quality Standard (NAAQS). Section 110 requires that each state adopt and submit a SIP revision to support the implementation, maintenance, and enforcement of each new or revised NAAQS promulgated by the EPA. These SIPs are commonly referred to as "infrastructure" SIPs. The infrastructure requirements are designed to ensure that the structural components of each state's air quality management program are adequate to meet the state's responsibilities under the CAA. The EPA is also proposing to approve a request from the state to exempt all counties in the Metropolitan Kansas City Interstate Air Quality Control Region (AQCR) and all of Jefferson and most of Franklin (except Boles Township) counties in the Metropolitan St. Louis Interstate AQCR from needing an ozone contingency plan meeting the requirements of our regulations.
