On June 20, 2002, the Minnesota Pollution Control Agency (MPCA) submitted to EPA a redesignation request and maintenance plan for the Saint Paul, Ramsey County particulate matter primary nonattainment area. In its submittal, the State requested that we redesignate Ramsey County to attainment of the National Ambient Air Quality Standards (NAAQS) for particulate matter with an aerodynamic diameter less than or equal to a nominal 10 micrometers (PM) and that we approve the maintenance plan for the area into the Minnesota PM State Implementation Plan (SIP). In this action EPA is approving the state's request, because it meets all of the Clean Air Act (Act) requirements for redesignation. If EPA receives adverse written comments on this action, we will publish a timely withdrawal of the direct final rule in the Federal Register informing the public that the rule will not take effect.
