110(a)(2)(C) Comment:

The State of Wyoming has a SIP

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

11 0(a)(2)(C) fo r the 2010 1

- hour N O 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 State from contributing significantly to nona ttainment, 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.

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 :

In a letter to the EPA from Governor Matt hew H. Mead dated 1/12/11, the State of Wyoming

recommended 1

- hour nitrogen dioxide “attainment” designations be made for all areas not under the jurisdiction of Tribal Authorities since the monitoring network in place showed no violations of NO 2 , and there are no re quirements upon the State to deploy a new monitoring network to measure traffic impacts. As noticed in 77 FR 9532 on 2/17/2012, all areas of the United States were designated as

“unclassifiable/attainment” for the 2010 1

- hour NO 2 NAAQS. The basis for des ignating these areas as “unclassifiable/attainment” is monitored air quality data from calendar years 2008

- 2010, indicating no

violations of the 1

- hour nitrogen dioxide NAAQS, thereby demonstrating that Wyoming is in compliance with CAA section 110(a)(2)(D )(i) for the 1

- hour NO 2 NAAQS and does not contribute to

nonattainment or interfe re with maintenance in another S tate.

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

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

9 | Page 110(a)(2)(E) Comment:

The State of Wyoming also receives sections 103 and 105 grant funds through its Performance Partnership Agreement (PPA ) 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 2010 1

- hour N O 2 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 2010 1

- hour N O 2 NAAQS.

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

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

the 2010 1

- hour N O 2 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.

1

- hour N O 2 NAAQS.

Plan Revisions for Nonattainment Areas: Section 110(a)(2)(I) requires, in the case of a SIP or SIP revision for a nonattainment area, the SIP must meet applicable requirements of part D relating to

nonattainment areas.

110(a)(2)(I) Comment:

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 )

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 u nder 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 2 010 1

- hour N O 2 NAAQS.

A ir q uality modeling/data: Section 110(a)(2)(K) requires that SIPs provide for performing air quality

110(a)(2)(K) Comment:

Wyoming’s PSD program requires that estimates of ambient air concentrations be based on applicable air quality m odels specified in Appendix W of 40 CFR part 51, an d that modification or substitution of a model specified in Appendix W must be approved by the Administrator.

Wyoming’s air quality modeling and the submission of data programs meet the requirements of CAA

- hour N O 2 NAAQS.

Permitting fees: Section 110(a)(2)(L) requires SIPs to require each major stationary source to pay permitting fees to cover the cost of reviewing, approving, implementing and enforcing a permit.
