Mr. James B. Martin Regional Administrator USEPA Region 8 Mail Code: 8P-AR 1595 Wynkoop Street Denver, CO 80202-1129 RE: 110 Infrastructure SIP for 2006 PM2.s NAAQS DearMr. Martin: John Corra, Director

Section 110(a)(1) ofthe CleanAirAct (CAA) requires that each state, after a newor revised National Ambient Air Quality Standard (NAAQS) is promulgated, reviewits State ImplementationPlans (SIPs) to ensure that they meetthe requirements ofthe "infrastructure elements" ofSection 110(a)(2) ofthe CAA. The State ofWyoming updated the list of documentation required to demonstrate that the State has addressed all fourteen basic infrastructure elements. Thelist was then taken outfor public notice beginning onJuly 16, 2011. A public hearing was held onAugust 16,2011 in Green River, Wyoming. Afterreceiving one positive comment, the State ofWyominghas made a determination thatthe PM2.5 Infrastructure SIP contains all ofthe necessaryprovisionsto address the requirements for the 2006 PM2
