Approval and Promulgation of Implementation Plans: Minnesota: Minneapolis-St. Paul Carbon Monoxide Maintenance Plan Update

EPA is proposing to approve a revision to the Minnesota State Implementation Plan (SIP) for the maintenance of the Carbon Monoxide (CO) ambient air quality standard (NAAQS) submitted on November 10, 2004. Specifically, EPA is proposing approval of Minnesota's revised 2009 emissions inventories and 2009 Motor Vehicle Emissions Budgets (MVEB) recalculated using MOBILE6 for the Minneapolis-St. Paul CO maintenance area. In the final rules section of this Federal Register, EPA is approving the SIP revision as a direct final rule without prior proposal, because EPA views this as a noncontroversial revision and anticipate no adverse comments. A detailed rationale for the approval is set forth in the direct final rule. If no adverse comments are received in response to this proposed rule, no further activity is contemplated in relation to this proposed rule. If EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule. EPA will not institute a second comment period on this action. Any parties interested in commenting on this action should do so at this time.
