RE: 110 Infrastructure SIP for the 2008 8-Hour Ozone National Ambient Air Quality

Standard (NAAQS)

Dear Mr. McGrath:

Section 11 O(a)(l) 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 l 10(a)(2). In response to the new 8-hour ozone NAAQS that was promulgated on March 12, 2008, the State of Wyoming updated the list of documentation required to demonstrate that the SIP meets the requirements of Sections l lO(a)(l) and (2) of the

CAA. The State of Wyoming has made a determination that the 8-hour ozone Infrastructure SIP

contains all the necessary provisions to address the requirements for the 2008 8-hour ozone NAAQS. The 2008 8-hour ozone Infrastructure SIP was taken out for public notice beginning

December 16, 2013. A public hearing was held in Cheyenne, Wyoming on January 15, 2014,

and no comments were received.

If you have any questions regarding this submittal or if you need further information, please feel free to contract Steven A. Dietrich, Air Quality Administrator, at 307-777-7391.

Sincerely,

The State of Wyoming has a SIP

- approved PSD program covering the requirements for all regulated NSR pollutants, including GHG, which meet s the requirements of 110(a)(2)(C). Emission limits and control measures that satisfy the requirements of 110(a)(2)(C) are identified under secti on 110(a)(2)(A)

“ Emission limits and other control measures

, ” included in this document.

Wyoming’s program for enforcement of control measures meet s the requirements of the CAA section 110(a)(2)(C) for the 2008 8

- hour o zone NAAQS.

Interstate and international transport provisions: Section 110(a)(2)(D) (i) 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 t he NAAQS in another State, or from interfering with measures required to prevent significant deterioration of air quality or to protect visibility in another State.

Section 110(a)(2)(D)(ii) requires SIPs to include adequate provisions insuring compliance with applicable requirements of sections 126 and 115 (relating to interstate and international pollution abatement)

110(a)(2)(D) Comment :

The WDEQ

- AQD (AQD) identified a nearby ozone nonattain ment area to be located in the S tate of Colorado. The AQD relies on wind rose plots and low ozone concentrations for Cheyenne, Wyoming to address the transport of ozone. Based on this information, the State of Wyoming confirms that ozone emissions from Wyoming do not contribute to nona ttainment or interfere with maintenance of

the 8

- hour 2008 ozone National Ambient Air Quality Standard (NAAQS) in Colorado or another S tate. (Attach ment A)

The State of Wyoming has one nonattainment area (NAA) for ozone. The NAA designation for the Uppe r Green River Basin (UGRB) became effective on 7/20/2012 per an EPA determination published in 77 FR 30158 on 5/21/2012. Based on the EPA designation of the UGRB as a NAA for 8

- hour ozone, and the subsequent acknowledgement by EPA (EPA to Governor Mead le tter 4/30/12) that remaining areas, inclu ding downwind counties, in the S tate do not violate or contribute to a violation of

the 8

- hour ozone standard, the State of Wyoming does not believe that it significantly contributes to

nonattainment or interfer es w ith maintenance in another S tate.WDEQ

110(a)(2)(E) Comment:

The State of Wyoming also receives sections 103 and 105 grant funds through its Performance Partnership Agreement (P PA ) grants along with required S tate matching funds to provide funding necessary to carry out Wyoming’s SIP requirements. The State has the authority, funding and adequate personnel to fulfill the requirements necessary to meet section 110(a)(2)(E)(i) for t he 2008 8

- hour

o zone NAAQS.

Wyoming statute s and Executive Orders provide the mechanisms to satisfy CAA section 128 and meet the requirements of CAA section 110(a)(2)(E)(ii) for the 2008 8

- hour o zone NAAQS.

The State does not rely upon any other local or regional government agency or instrumentality for implementation of the SIP

, and therefore meets the requirements of CAA section 110(a)(2)(E)(iii) for

the 2008 8

- hour o zone NAAQS.

Stationary source monitoring system: Section 110(a)(2)(F) requires States to establish a system to monitor emissions from stationary sources and to submit periodic emissions reports.

According to EPA’s interpretation of the CAA, section 110(a)(2)(I) Plan Revisions for Nonattainment

Areas will not be addressed in the context of an infrastructure SIP and air agencies do not need to

address Element I in an infrastructure SIP submission

. Section 110(a)(2)(I) infrastructure eleme nts will be reviewed and acted upon through a separate process. ( Guidance on Infrastructure State Implementation Plan (SIP) Elements under Clean Air Act Sections 110(a)(1) and 110(a)(2), September 13, 2013, OAQPS )

EPA recognizes that S tates are subject to visibility and regional haze program requirem ents under part

C of the CAA. Visibility and regional haze program requirements under part C do not change when a new NAAQS becomes effective

, and therefore no new vis ibility obligations are “triggered” for the State of Wyoming under section 110(2)(2)(J).
