Approval and Promulgation of Air Quality Implementation Plans; Minnesota

March 11, 2010 by admin

EPA is approving a site-specific revision to the Minnesota State Implementation Plan (SIP) for particulate matter less than 10 microns (PM 10 ) for Aggregate Industries Yard A Facility in Saint Paul, Ramsey County, Minnesota. On May 19, 2009, the Minnesota Pollution Control Agency (MPCA) requested that EPA approve certain portions of a joint Title I/Title V document into the Minnesota PM 10 SIP for this facility. The State is also requesting in this submittal that EPA rescind the Administrative Order (AO) issued to J.L. Shiely Company which is currently included in Minnesota's SIP for PM 10 . The emissions units previously owned by J.L. Shiely Company are now owned by Aggregate Industries. Because the PM 10 emission limits are being reduced, the air quality of Ramsey County will be protected.
