Environmental Protection Agency (EPA).
The Environmental Protection Agency (EPA) is approving portions of an August 19, 2011 State Implementation Plan (SIP) submission from the State of Wyoming that are intended to demonstrate that its SIP meets certain interstate transport requirements of the Clean Air Act (Act or CAA) for the 2006 24-hour fine particulate matter (PM2.5) National Ambient Air Quality Standards (NAAQS). This submission addresses the requirement that Wyoming's SIP contain adequate provisions prohibiting air emissions that will have certain adverse air quality effects in other states. Specifically, EPA is approving the portion of the Wyoming SIP submission that addresses the significant contribution to nonattainment and interference with maintenance transport requirements for the 2006 24-hour PM2.5 NAAQS. EPA is also approving the interference with prevention of significant deterioration (PSD) of air quality transport requirement for this NAAQS. EPA is not acting on the interference with visibility transport requirement at this time and will address the visibility requirement for this NAAQS in a separate future action.
This final rule is effective on September 9, 2015.

A. 2006 PM 2.5 NAAQS and Interstate Transport
On September 21, 2006, EPA promulgated a final rule revising the 1997 24-hour primary and secondary NAAQS for PM2.5 from 65 micrograms per cubic meter (µg/m3) to 35 µg/m3 (October 17, 2006, 71 FR 61144).
Section 110(a)(1) of the CAA requires each state to submit to EPA, within three years (or such shorter period as the Administrator may prescribe) after the promulgation of a primary or secondary NAAQS or any revision thereof, a SIP that provides for the “implementation, maintenance, and enforcement” of such NAAQS. EPA refers to these specific submittals as “infrastructure” SIPs because they are intended to address basic structural SIP requirements for new or revised NAAQS. For the 2006 24-hour PM2.5 NAAQS, these infrastructure SIPs were due on September 21, 2009. CAA section 110(a)(2) includes a list of specific elements that “[e]ach such plan submission” must meet.
The interstate transport provisions in CAA section 110(a)(2)(D)(i) (also called “good neighbor” provisions) require each state to submit a SIP that prohibits emissions that will have certain adverse air quality effects in other states. CAA section 110(a)(2)(D)(i) identifies four distinct elements related to the impacts of air pollutants transported across state lines. The two elements under 110(a)(2)(D)(i)(I) require SIPs to contain adequate provisions to prohibit any source or other type of emissions activity within the state from emitting air pollutants that will (element 1) contribute significantly to nonattainment in any other state with respect to any such national primary or secondary NAAQS, and (element 2) interfere with maintenance by any other state with respect to the same NAAQS. The two elements under 110(a)(2)(D)(i)(II) require SIPs to contain adequate provisions to prohibit emissions that will interfere with measures required to be included in the applicable implementation plan for any other state under part C (element 3) to prevent significant deterioration of air quality or (element 4) to protect visibility.
On August 19, 2011, the Wyoming Department of Environmental Quality (WDEQ) made a submission certifying that Wyoming's SIP is adequate to implement the 2006 24-hour PM2.5 NAAQS for all the “infrastructure” requirements of CAA section 110(a)(2). On April 23, 2015, WDEQ sent EPA a letter clarifying its August 19, 2011 submission with regard to elements 1-3 of CAA section 110(a)(2)(D)(i). EPA proposed approval of 110(a)(2)(D)(i) elements 1-3 of Wyoming's August 19, 2011 submission on May 18, 2015 (80 FR 28209).
II. Response to Comments
EPA did not receive any comments on the May 18, 2015 proposal.
III. Final Rule
EPA is approving the 110(a)(2)(D)(i)(I) portion of Wyoming's August 19, 2011 submission. We are approving elements 1 and 2 of this portion of the submission based on EPA's supplemental evaluation of relevant technical information, which supports a finding that emissions from Wyoming do not significantly contribute to nonattainment or interfere with maintenance of the 2006 24-hour PM2.5 NAAQS in any other state and that the existing Wyoming SIP is, therefore, adequate to meet the requirements of CAA section 110(a)(2)(D)(i)(I) for the 2006 24-hour PM2.5 NAAQS.
EPA is also approving element 3 of 110(a)(2)(D)(i) from Wyoming's August 19, 2011 submission, based on a finding that the Wyoming SIP is adequate to meet the PSD requirement of CAA section 110(a)(2)(D)(i)(II).
IV. Statutory and Executive Orders Review
Under the CAA, the Administrator is required to approve a SIP submission that complies with the provisions of the Act and applicable federal regulations (42 U.S.C. 7410(k), 40 CFR 52.02(a)). Thus, in reviewing SIP submissions, EPA's role is to approve state choices, provided that they meet the criteria of the CAA. Accordingly, this action merely approves state law as meeting federal requirements; this action does not impose additional requirements beyond those imposed by state law. For that reason, this action:
- Is not a “significant regulatory action” subject to review by the Office of Management and Budget under Executive Order 12866 (58 FR 51735, October 4, 1993);
- Does not impose an information collection burden under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
- Is certified as not having a significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.);
- Does not contain any unfunded mandate or significantly or uniquely affect small governments, as described in the Unfunded Mandates Reform Act of 1995 (Pub. L. 104-4);
- Does not have federalism implications as specified in Executive Order 13132 (64 FR 43255, August 10, 1999);
- Is not an economically significant regulatory action based on health or safety risks subject to Executive Order 13045 (62 FR 19885, April 23, 1997);
- Is not a significant regulatory action subject to Executive Order 13211 (66 FR 28355, May 22, 2001);
- Is not subject to requirements of Section 12(d) of the National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) because application of those requirements would be inconsistent with the CAA; and,
- Does not provide EPA with the discretionary authority to address, as appropriate, disproportionate human health or environmental effects, using practicable and legally permissible methods, under Executive Order 12898 (59 FR 7629, February 16, 1994).
The SIP is not approved to apply on any Indian reservation land or in any other area where EPA or an Indian tribe has demonstrated that a tribe has jurisdiction. In those areas of Indian country, the rule does not have tribal implications and will not impose substantial direct costs on tribal governments or preempt tribal law as Start Printed Page 47859specified by Executive Order 13175 (65 FR 67249, November 9, 2000).
The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the Small Business Regulatory Enforcement Fairness Act of 1996, generally provides that before a rule may take effect, the agency promulgating the rule must submit a rule report, which includes a copy of the rule, to each House of the Congress and to the Comptroller General of the United States. EPA will submit a report containing this action and other required information to the U.S. Senate, the U.S. House of Representatives, and the Comptroller General of the United States prior to publication of the rule in the Federal Register. A major rule cannot take effect until 60 days after it is published in the Federal Register. This action is not a “major rule” as defined by 5 U.S.C. 804(2).
Under section 307(b)(1) of the Clean Air Act, petitions for judicial review of this action must be filed in the United States Court of Appeals for the appropriate circuit by October 9, 2015. Filing a petition for reconsideration by the Administrator of this final rule does not affect the finality of this action for the purposes of judicial review nor does it extend the time within which a petition for judicial review may be filed, and shall not postpone the effectiveness of such rule or action. This action may not be challenged later in proceedings to enforce its requirements. (See CAA section 307(b)(2).)Start List of Subjects
