Approval and Promulgation of Implementation Plans; State of Missouri; St. Louis Area Transportation Conformity Requirements

Résumé

EPA is taking direct final action to approve revisions to the Missouri State Implementation Plan (SIP) submitted March 22, 2011. This revision does not add any additional requirements to the existing rule but amends the rule by adding language that better clarifies specific roles and responsibilities to the interagency consultation process requirements. The revisions to Missouri's rule do 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).
