On September 7, 1994, the Minnesota Pollution Control Agency (MPCA) submitted a request for redesignation to attainment for particulate matter (PM) in the Rochester portion of Olmsted County and sulfur dioxide (SO<INF>2) in the Air Quality Control Region (AQCR) 131 Twin Cities and Pine Bend areas (excluding the St. Paul Park area). A revision to the administrative order for Rochester Public Utilities (RPU) was also submitted in support of the Olmsted County redesignation request. The USEPA is approving, through the use of direct final rulemaking procedures, the redesignation requests and the administrative order revision for RPU.
