RE: 110 Infrastructure SIP for 2008 Lead (Pb) NAAQS 

Dear Mr. Martin: 

John Corra, Director 

Section 11 0( a)( 1) of the Clean Air Act (CAA) requires that each state, after a new or 

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

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

elements" of Section 11 O(a)(2). In response to the revised primary and secondary lead NAAQS 

that was promulgated on October 15, 2008, the State of Wyoming updated the list of 

documentation required to demonstrate that the SIP meets the requirements of Sections 11 O(a)(l) 

and (2) of the CAA. The State of Wyoming has made a determination that the updated SIP 

contains all of the necessary provisions to address the requirements for the 2008 primary and 

secondary lead NAAQS. The lead infrastructure SIP was taken out for public notice beginning 

on September 2, 2011. A public hearing was held in Cheyenne, Wyoming on October 4, 2011 , 

and no comments were received. 

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

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

110 SIP INFRASTRUCTURE ELEMENTS FOR LEAD 

(Reviewed August 2011) 

Emission limits and other control measures: Section 110(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)(I) are subject to the timing requirement of section 172, not the 

timing requirement of section 11 O(a)(1 ), and also that SIPs to meet this section are not covered 

by the Consent Decree.

Interstate transport: Section 11 O(a)(2)(D) requires SIPs to include provisions prohibiting any 

source or other type of emissions activity in one State from contributing significantly to 

nonattainment, or interfering with maintenance, of the NAAQS in another State, or from 

interfering with measures required to prevent significant deterioration of air quality or to protect 

visibility in another State. EPA has already issued CAIR to assist States in developing SIPs to 

meet this requirement for purposes of the 8-hour Ozone and PM2.5 NAAQS, and has issued 

separate guidance to all States on how to comply with each prong of this statutory provision.

j. Negative Declaration Demonstration 

2. Wyoming does not have any lead sources that are in close proximity (2 miles) to state 

borders. Therefore, it can be concluded that emissions from lead sources within 

Wyoming do not contribute significantly to nonattainment in other states, or interfere 

with maintenance in neighboring states.

2. Wyoming Environmental Quality Act, Article 2, Notification to the Environmental 

Protection Agency and contiguous states (Section 35-11-207 ofthe Wyoming Statutes) 

3. Wyoming has established the Air Quality Advisory Board (AQAB) as required in the Air 

Pollution Control Act. The AQAB is comprised of representatives from the government, 

industry, and members of the public, with the largest membership residing with the 

public. The Board does not approve or enforce permits, but rather makes 

recommendations to the Division on air pollution issues. Therefore, there is not a conflict 

of interest associated with the AQAB. The Environmental Quality Council (EQC) does 

have the ability to overrule the Division's permitting actions, but the EQC is restricted by 

the Environmental Quality Act. Council members that receive greater than ten percent of 

their income from any permit applicant are restricted from acting on that permit 

application. 

4. The Wyoming Department of Environmental Quality is responsible for approving and 

enforcing permits. 

Adequate resources: Section 110(a)(2)(E) requires States to provide for adequate personnel, 

funding, and legal authority under State law to carry out its SIP, and related issues.

4. Wyoming does not contain any sources that have significant lead emissions. Due to the 

lack of priority region classifications from EPA for lead, and the small quantity of 

potential lead emissions in the state, the Division has determined that an emergency 

action plan and contingency plan are not necessary.
