RE:	 110 InCrastructure SIP for Ozone 

Dear Ms. Dolan: 

On December 7, 2007, the State submitted a letter to EPA Region 8 regarding the adequacy of 

the existing SIP with respect to the 1997 ozone standards. The attached document outlines the 

provisions of Wyoming Rules and Regulations which address the requirements of Section 

I 10(a)(1) and (2) of the Clean Air Aet. If you have any questions, please call me at 307-777­

7032.

110 SIP INFRASTRUCTURE ELEMENTS 

(Reviewed March 2008) 

Emission limits and other control measures: Section 11 0(a)(2)(A) requires SIPs to include 

enforceable emission limits and other control measures, means or techniques, schedules for 

compliance and other related matters. EPA notes that the specific nonattainment area plan 

requirements of section 11 O( a)(2 )(1) are subject to the timing requirement of section 172, not the 

timing requirement of section 11 O(a)(J), and also that SIPs to meet this section are not covered 

by the Consent Decree.
