Approval and Promulgation of Implementation Plans; Minnesota

요약

In this action, the USEPA is proposing to disapprove the revision to Minnesota's State Implementation Plan (SIP) for sulfur dioxide (SO 2) for the Dakota County/Pine Bend area of Air Quality Control Region 131. Assuming no other substantive, adverse public comments are received, the USEPA will proceed with a final approval of the submittal when the Minnesota Pollution Control Agency (MPCA) addresses the concerns detailed in this notice and submits the Administrative Orders to USEPA before the end of the 30-day comment period. The USEPA's action is based upon a revision request which was submitted by the State to satisfy the requirements of the Clean Air Act. The revisions are the result of a call for SIP revision issued by USEPA on December 5, 1984, based on monitored violations. The revisions in the Minnesota submittal are in the form of non-expiring Findings and Orders for Koch Refining Company and Koch Sulfuric Acid Unit, Continental Nitrogen and Resources Company, and Northern States Power Company-Inver Hills Generating Facility. DATES: Comments on this requested revision and on the proposed USEPA action must be received by February 28, 1994.
