EPA is approving a request submitted by the Minnesota Pollution Control Agency (MPCA) on July 29, 2010, to revise the Minnesota State Implementation Plan (SIP) for lead (Pb) under the Clean Air Act (CAA). The State has submitted a joint Title I/Title V document (joint document) in the form of Air Emission Permit No. 03700016-003, and has requested that the conditions laid out with the citation "Title I Condition: SIP for Lead NAAQS" replace an existing Administrative Order (Order) as the enforceable SIP conditions for Gopher Resource, LLC. The existing Order was approved by EPA on October 18, 1994. MPCA's July 29, 2010, revisions were meant to satisfy the maintenance requirements for the 1978 Pb National Ambient Air Quality Standard (NAAQS), promulgated at 1.5 micrograms per cubic meter, or 1.5 [mu]g/m<SUP>3</SUP>.
