II. Background of Wyoming's Submissions

On August 19, 2011, the State of Wyoming submitted to EPA a formal revision package detailing two rulemakings (R-4 and R-18) as revisions to Wyoming's SIP. These revisions amend the WAQSR. In particular, Wyoming has revised chapter 2, “Ambient Standards,” section 2, “Ambient standards for particulate matter,” section 10, “Ambient standards for lead,” and section 12, “Incorporation by reference.”

The Wyoming Environmental Quality Council made these changes by amending chapter 2, including sections 2, 10 and 12, via rulemakings R-4 and R-18 on February 18, 2000, and July 8, 2010, respectively. In accordance with the Wyoming Administrative Procedures Act, the revisions were forwarded to the Wyoming Governor's Office where they were approved, and then transmitted to the Wyoming Secretary of State's office and became effective on March 30, 2000 and September 7, 2010, respectively. All necessary State reviews and approvals have been secured.

In rulemaking R-4, section 2, the particulate matter ambient standards were amended to adopt the 24-hour and annual PM_2.5 standards into the State rule. Rulemaking R-18 made the State PM_2.5 ambient standards consistent with federal standards, but no more stringent than federal standards, while deleting the annual PM₁₀ standard and retaining the 24-hour ambient air quality standard for PM₁₀. R-18 also amended section 10, the Pb ambient standard, making Wyoming's Pb ambient standard consistent with, but no more stringent than, the federal standard, and added section 12 to consolidate all incorporation by references for the chapter into one section.

III. EPA's Evaluation of Wyoming's Submissions

The SIP revisions in the August 19, 2011 submittal that we are acting on in this document involve chapter 2, “Ambient Standards,” section 2, “Ambient standards for particulate matter,” section 10, “Ambient standards for lead,” and section 12, “Incorporation by reference.” To determine if Wyoming's submissions should be approved by EPA, EPA must evaluate the submissions for consistency with the CAA and EPA regulations.

In rulemaking R-4, section 2, the particulate matter ambient standards were amended to adopt the annual and 24-hour PM_2.5 NAAQS into the State rule. This is consistent with the CAA as in 1997 EPA established annual and 24-hour NAAQS for PM_2.5 for the first time. This requirement has been part of WAQSR since its incorporation on February 18, 2000.

In rulemaking R-18, section 2 was amended to make the State PM_2.5 ambient standards consistent with federal standards, but no more stringent than federal standards. The section now sets the primary and secondary ambient air quality standards for PM_2.5 at 15 micrograms per cubic meter (ug/m3) annual arithmetic mean concentration, and; 35 micrograms per cubic meter (ug/m3)—98th percentile 24-hour average concentration. The change defines attainment of the annual and 24-hour standards in accordance with Appendix N of 40 CFR part 50. It further sets the measurement of PM_2.5, for the purpose of determining attainment of the standards, as determined by a reference method based on 40 CFR part 50, Appendix L and designated in accordance with 40 CFR part 53 or an equivalent or alternate method designated in accordance with 40 CFR Part 53. The revision also retains the 24-hour PM₁₀ ambient air standards for PM₁₀ particulate matter at 150 micrograms per cubic meter 24-hour average concentration with not more than one expected exceedance per year, and defines attainment of the 24-hour standard as determined in accordance with Appendix K of 40 CFR part 50. These changes correlate with the requirements of 40 CFR parts 50 and 53 as of the August 19, 2011 date of Wyoming's submittal. The State also removed the annual PM₁₀ standard from their regulations. This is permissible as the EPA revoked the annual PM₁₀ NAAQS in a 2006 rulemaking (71 FR 61224, October 17, 2006).

In rulemaking R-18, section 2 was further amended to make the State Pb ambient standards consistent with federal standards, but no more stringent than federal standards. The section now sets the primary and secondary ambient air quality standards for Pb at 0.15 micrograms per cubic meter, arithmetic mean concentration over a 3-month period. It further defines the measurement of Pb in the ambient air as Pb either by: a reference method based on 40 CFR part 50, Appendix G and designated in accordance with 40 CFR part 53, or an equivalent method designated in accordance with 40 CFR part 53. The section now defines that primary and secondary ambient air quality standards for Pb are met when the maximum arithmetic 3-month mean concentration for a 3-year period, as determined in accordance with Appendix R of 40 CFR part 50, is less than or equal to 0.15 micrograms per cubic meter. These changes correlate with the requirements of 40 CFR parts 50 and 53 as of the August 19, 2011 date of Wyoming's submittal.

Finally, in rulemaking R-18, Chapter 2 was amended by adding a new section 12 “Incorporation by reference.” This section was added to simply consolidate all adoption by reference for Chapter 2 in one place. It defines the CFRs cited in the chapter as those published as of July 1, 2008, and details where copies of the applicable CFRs can be found for public inspection and to obtain copies. These changes correlate with the requirements of 40 CFR parts 50 and 53 as of the August 19, 2011 date of Wyoming's submittal.

EPA has reviewed Wyoming's rule amendments and additions analyzed above. These rules mirror applicable language in 40 CFR parts 50 and 53. The changes quoted above provide the regulation necessary for the State to determine compliance with the CAA for PM_2.5, PM₁₀ and Pb NAAQS. Therefore, these WAQSR changes and additions are consistent with the CAA and EPA regulations. As a result, EPA is approving a SIP revision submitted by the State of Wyoming consisting of the above discussed applicable portions of rulemakings R-4 and R-18 submitted on August 19, 2011 to EPA Region 8.

IV. Consideration of Section 110(l) of the CAA

Under section 110(l) of the CAA, EPA cannot approve a SIP revision if the revision would interfere with any applicable requirements concerning attainment and reasonable further progress toward attainment of the NAAQS or any other applicable requirement of the Act. In addition, section 110(l) requires that each revision to an implementation plan submitted by a state shall be adopted by such state after reasonable notice and public hearing.

The Wyoming SIP revisions that EPA approves today do not interfere with attainment of the NAAQS or any other applicable requirement of the Act. The first revision (R-4) revises the WAQSR particulate matter ambient standard to adopt the annual and 24-hour PM_2.5 standards into the State rule. The second revision (R-18) makes the State annual and 24-hour PM_2.5 and Pb ambient standards consistent with federal standards, but no more stringent than federal standards. This revision also adds a section that simply consolidates all adoption by reference for chapter 2 in one place. The revisions were adopted after reasonable public notice, and after public hearings held on February 17, 2000, and July 8, 2010, respectively. All necessary State reviews and approvals have been secured. Therefore, CAA section 110(l) requirements are satisfied.

V. Final Action

EPA is approving SIP revisions that Wyoming submitted to EPA Region 8 on August 19, 2011. The Environmental Quality Council of the Wyoming Department of Environmental Quality adopted revisions to Chapter 2, “Ambient Standards,” Section 2,”Ambient standards for particulate matter,” Section 10, “Ambient standards for lead,” and Section 12, “Incorporation by reference,” of the WAQSR as revisions to the SIP.

EPA is publishing this rule without prior proposal because we view this as a noncontroversial amendment and anticipate no adverse comments. However, in the Proposed Rules section of today's Federal Register publication, we are publishing a separate document that will serve as the proposal to approve the SIP revision if adverse comments are filed. This rule will be effective October 27, 2014 without further notice unless we receive adverse comments by September 25, 2014. If we receive adverse comments, we will publish a timely withdrawal in the Federal Register informing the public that the rule will not take effect. We will address all public comments in a subsequent final rule based on the proposed rule. We will not institute a second comment period on this action. Any parties interested in commenting must do so at this time. Please note that if we receive adverse comment on an amendment, paragraph, or section of this rule and if that provision may be severed from the remainder of the rule, we may adopt as final those provisions of the rule that are not the subject of an adverse comment.

VI. Statutory and Executive Orders Reviews

Under the CAA, the Administrator is required to approve a SIP submission that complies with the provisions of the CAA 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 and 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).

In addition, this rule does not have tribal implications as specified by Executive Order 13175 (65 FR 67249, November 9, 2000), because the SIP is not approved to apply in Indian country located in the State, and EPA notes that it will not impose substantial direct costs on tribal governments or preempt tribal law.

The Congressional Review Act, 5 U.S.C. section 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 rule 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. section 804(2).

Under section 307(b)(1) of the CAA, petitions for judicial review of this action must be filed in the United States Court of Appeals for the appropriate circuit by October 27, 2014. 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. Parties with objections to this direct final rule are encouraged to file a comment in response to the parallel notice of proposed rulemaking for this action published in the proposed rules section of today's Federal Register, rather than file an immediate petition for judicial review of this direct final rule, so that EPA can withdraw this direct final rule and address the comment in the proposed rulemaking. This action may not be challenged later in proceedings to enforce its requirements. (See section 307(b)(2).)
