Abstract
The Environmental Protection Agency (EPA) is taking direct final action to approve revisions to the State Implementation Plan (SIP) for the state of Missouri. The revisions address base year Emissions Inventory (EI) and emissions statement requirements of the Clean Air Act (CAA) for the Missouri portion of the St. Louis marginal ozone nonattainment area ("St. Louis area"). The Missouri counties comprising the St. Louis area are Franklin, Jefferson, St. Charles, and St. Louis along with the City of St. Louis. EPA is taking final action to approve the SIP revisions because they satisfy the CAA section 182 requirements for the 2008 8-hour ozone National Ambient Air Quality Standards (NAAQS). EPA is approving the revisions pursuant to section 110 and part D of the CAA and EPA's regulations. EPA will consider and take action on the Illinois submission for its portion of the St. Louis area in a separate action.
