Abstract
EPA is taking direct final action to approve revisions to the Missouri State Implementation Plan (SIP) submitted September 21, 2010. This revision will amend the ambient air quality standards table to reflect revised National Ambient Air Quality Standards (NAAQS), update reference methods associated with the revised NAAQS, and update the breakpoint values for the Air Quality Index. These revisions make Missouri's rules consistent with Federal regulations and improve the clarity of the rules. EPA's approval of this SIP revision is being done in accordance with the requirements of the Clean Air Act (CAA).
