SUPPLEMENTARY INFORMATION:

Throughout this document whenever “we,” or “our” is used, it refers to the EPA.

I. Background

On January 13, 2022, Oregon submitted a request for the EPA to redesignate the Oakridge nonattainment area to attainment for the 2006 24-hour PM_2.5 NAAQS under section 107(d)(3)(E) of the CAA. On May 5, 2022, the EPA proposed to determine that the Oakridge, Oregon nonattainment area met the statutory requirements for redesignation under the CAA and proposed to approve, as a revision to the Oregon SIP, the State's plan for maintaining the 2006 24-hour PM_2.5 NAAQS through the year 2035 (87 FR 26710). The EPA's proposed approval was based upon the EPA's determination that the area continues to attain the 2006 24-hour PM_2.5 NAAQS ^[1] and that all other redesignation criteria have been met for the area. In addition, in accordance with 40 CFR 93.118(f)(2), the EPA proposed to find adequate and approve the Oakridge 2015, 2025, 2030 and 2035 PM_2.5 motor vehicle emission budgets for use in transportation conformity determinations.

An explanation of the CAA requirements, a detailed analysis of the submittal, and the EPA's reasons for approval were provided in the notice of proposed rulemaking and will not be restated here. The public comment period closed on June 6, 2022. We received no public comments, therefore, we are finalizing the action as proposed.

II. Final Action

The EPA is redesignating the Oakridge, Oregon PM_2.5 area to attainment and we are approving the associated maintenance plan as a revision to the Oregon SIP. The designation status of the Oakridge, Oregon PM_2.5 area under 40 CFR part 81 will be revised to attainment upon the effective date of this final action. We are also finding adequate and approving the PM_2.5 motor vehicle emission budgets included in the Oakridge maintenance plan.

In addition, the EPA is approving and incorporating by reference into the Oregon SIP, the submitted revisions to LRAPA Title 29 to reflect the Oakridge area's revised air quality designations, updated area names, and shift from the list of nonattainment areas to the list of maintenance areas; specifically, sections 29-0010, 29-0020, 29-0030, 29-0040, 29-0050, 29-0060, 29-0070, 29-0080, 29-0090, 29-0300, 29-0310 and 29-0320 (regulations governing the designation of air quality areas in Lane County, Oregon and their legal descriptions), State effective November 18, 2021.

Finally, the EPA is approving and incorporating into the SIP the Lane County Code Chapter 9—Restriction on Use of Solid Fuel Space Heating Devices, Sections 9.120-9.140 (regulating the use of solid fuel heating devices to reduce particulate emissions and improve air quality), and the City of Oakridge Ordinance No. 920—An Ordinance Amending Section 7 of Ordinance 914 and Adopting New Standards for the Oakridge Air Pollution Control Program; Section Two (3)—Solid Fuel Burning Devices—Prohibitions (prohibiting emissions from solid-fuel heating devices with an opacity greater than 20%). Upon the effective date of this action the SIP will contain the Oakridge Ordinance No. 920, city approved October 20, 2016 (except section 6) and the Lane County Code Chapter 9, county approved February 9, 2017 (except 9.145 and 9.150). Incorporation of these measures will strengthen the Oregon SIP and ensure PM_2.5 emission reductions in the Oakridge area.

We note, the EPA is taking separate and final action on the Oakridge PM₁₀ redesignation request, and maintenance plan, which were also included in the January 13, 2022 submission. ( printed page 51263)

III. Incorporation by Reference

In this document, the EPA is finalizing regulatory text that includes incorporation by reference. In accordance with the requirements of 1 CFR 51.5, we are finalizing the incorporation by reference of the LRAPA regulatory provisions described in section II of this preamble. The EPA has made, and will continue to make, these materials generally available through https://www.regulations.gov and at the EPA Region 10 Office (please contact the person identified in the FOR FURTHER INFORMATION CONTACT section of this preamble for more information). Therefore, these materials have been approved by the EPA for inclusion in the SIP, have been incorporated by reference by the EPA into that plan, are fully federally enforceable under sections 110 and 113 of the Clean Air Act as of the effective date of the EPA's approval of the final rule, and will be incorporated by reference in the next update to the SIP compilation.^[2]

IV. Statutory and Executive Order Review

Under the Clean Air Act, the Administrator is required to approve a SIP submission that complies with the provisions of the Clean Air Act and applicable Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in reviewing SIP submissions, the EPA's role is to approve state choices, provided that they meet the criteria of the Clean Air Act. 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 Orders 12866 (58 FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21, 2011);
• 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 inExecutive Order 13132 (64 FR 43255, August 10, 1999);
• Is not an economically significant regulatory action based on health or safety risks subject toExecutive Order 13045 (62 FR 19885, April 23, 1997);
• Is not a significant regulatory action subject toExecutive 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 Clean Air Act; and
• Does not provide the EPA with the discretionary authority to address, as appropriate, disproportionate human health or environmental effects, using practicable and legally permissible methods, underExecutive Order 12898 (59 FR 7629, February 16, 1994).

In addition, the SIP is not approved to apply on any Indian reservation land or in any other area where the 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 specified by Executive Order 13175 (65 FR 67249, November 9, 2000).

This action is subject to the Congressional Review Act, and the EPA will submit a rule report to each House of the Congress and to the Comptroller General of the United States. 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 21, 2022. 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 section 307(b)(2).)
