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 section 1 10(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 2010 1

- hour SO 2 NAAQ S.

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 s tate from contributing significantly to nonattainment, or interfering with maintenance, of t he NAAQS in another s tate, or from interfering with measures required to prevent significant deterioration of air quality

, or to protect visibility

, in another s tate.

Section 110(a)(2)(D)(ii) requires SIPs to include adequate provisions insuring complian ce 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 area as designated nonattainment for the 1

- hour sulfur dioxide (SO 2 ) National Ambient Air Q uality Standard (NAAQS) in the S tate of Montana. The AQD relies on distance between sources and wind rose plots from District 3 in Wyoming to address the transport of SO 2 . Based on this information, the State of Wyoming confirms that SO 2 emissions from Wyoming do not contribute to nonattainment or interfere wit h maintenance of the 1

- hour SO 2 NAAQS

in Montana or another s tate

, and therefore meet the requirements of 110(a)(2)(D)(i)(I)

. (Attachment A)

No source or sources within the S tate are the subject of an active finding under section 126 of the CAA

, and t her e are no final findings under section 115 of the CAA against Wyoming with respect to the 2010

1

- hour SO 2 NAAQS . T herefore

, Wyoming’s infrastructure SIP meets the requirements of CAA section 110(a)(2)(D)(ii) for the 2010 1

- hour SO 2 NAAQS.

Adequate personnel, funding and authority: Section 110(a)(2)(E) requires s tates to provide for adequate personnel, funding, and legal authority under s tate law, and CAA section 128 requirements to carry out its SIP.

According to EPA’s interpretation of the CAA, S ection 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 elements 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 )

110(a)(2)(J) Comment:

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 visibility obligations are “triggered” for the State of Wyoming under section 110(2)(2)(J).

Wyoming’ s process for consultation with government officials, public notification, PSD and visibility protection meet s the requirements of CAA section 110(a)(2)(J) for the 2010 1

- hour SO 2 NAAQS.

A ir q uality modeling/data: Section 110(a)(2)(K) requires that SIPs provide for performing air quality modeling for predicting effects on air quality of emissions from any NAAQS pollutant

, and submission of such data to EPA upon request.
