RE: 110 Infrastructure SIP for 2006 PM2.s NAAQS 

Dear Mr. Martin: 

John Corra, Director 

Section 110(a)(1) ofthe Clean Air Act (CAA) requires that each state, after a new or 

revised National Ambient Air Quality Standard (NAAQS) is promulgated, review its State 

Implementation Plans (SIPs) to ensure that they meet the requirements of the "infrastructure 

elements" of Section 11 0( a)(2) of the CAA. The State of Wyoming updated the list of 

documentation required to demonstrate that the State has addressed all fourteen basic 

infrastructure elements. The list was then taken out for public notice beginning on July 16, 2011. 

A public hearing was held on August 16,2011 in Green River, Wyoming. After receiving one 

positive comment, the State of Wyoming has made a determination that the PM2.

5 Infrastructure 

SIP contains all of the necessary provisions to address the requirements for the 2006 PM2.s 

NAAQS. 

If you have any questions regarding this submittal, please feel free to contact Steven A. 

Dietrich, Air Quality Administrator, at 307-777-7391. 

Sincerely,
