EPA is approving a site-specific revision to the Minnesota State Implementation Plan (SIP) for particulate matter less than 10 microns (PM-10) for Lafarge North America Corporation (Lafarge), Childs Road Terminal located in Saint Paul, Ramsey County, Minnesota. In its December 18, 2006, submittal, the Minnesota Pollution Control Agency (MPCA) requested that EPA approve certain conditions contained in Lafarge's federally enforceable state operating permit (FESOP) into the Minnesota PM SIP. The request is approvable because it satisfies the requirements of the Clean Air Act (Act). We are also taking action on Minnesota's request to revoke the Administrative Order for Lafarge that EPA had previously approved into the Minnesota SIP. The rationale for the approval and other information are provided in this rulemaking action.
