EPA is approving a request submitted by the Minnesota Pollution Control Agency (MPCA) on October 9, 2008, to revise the Minnesota State Implementation Plan (SIP) for particulate matter less than 10 microns (PM<INF>10</INF>). The approval revises the Minnesota SIP by updating information regarding the steel mini-mill facility located at 1678 Red Rock Road, St. Paul, Minnesota. The approval acknowledges the change of ownership and operation of the source from North Star Steel Company to Gerdau Ameristeel US Inc. The revision also amends the SIP by removing the Administrative Order issued to North Star Steel Company, and replacing the SIP conditions from the Administrative Order and placing those SIP requirements in a joint Title I/Title V document for Gerdau Ameristeel US, Inc. These revisions will not result in an increase in PM<INF>10</INF> emissions because no emission limits were increased.
