Approval and Promulgation of Implementation Plans; State of Missouri; Conformity of General Federal Actions to State Implementation Plans

요약

EPA proposes to approve the State Implementation Plan (SIP) revision submitted by the state of Missouri on August 12, 2011. This revision proposes to update the state general conformity rule in its entirety to bring it into compliance with the Federal general conformity rule which was updated in the Federal Register on April 5, 2010. General conformity regulations prohibit Federal agencies from taking actions that may cause or contribute to violations of the National Ambient Air Quality Standards (NAAQS). This rule applies to non-attainment and maintenance areas of the state. The revision to Missouri's rule does not have an adverse affect on air quality. EPA's approval of this SIP revision is being done in accordance with the requirements of the Clean Air Act (CAA).
