Approval and Promulgation of Implementation Plans; Minnesota

摘要

On November 26, 1991, and August 31, 1992, and November 13, 1992, the State of Minnesota submitted revisions to its State Implementation Plans (SIPs) for particulate matter. These SIP revisions were submitted by the State of Minnesota for the purpose of bringing about the attainment of the national ambient air quality standards (NAAQS) for particulate matter for the Saint Paul and Rochester nonattainment areas, and for the purpose of satisfying certain Federal requirements for SIPs for such areas. USEPA proposed to approve these SIP revisions on June 25, 1993. One commenter commented on this proposal, and Minnesota provided further submittals on February 3, 1993, April 30, 1993, and October 15, 1993. USEPA is granting full approval of the particulate matter SIP revisions for both areas.
