I. Background

On April 1, 2024, the EPA proposed to approve revisions to the Oregon SIP to strengthen and streamline the stationary source permitting rules (89 FR 22363). The reasons for our proposed action are included in the proposal and will not be restated here. The public comment period closed on May 1, 2024. We received four comments from members of the public. The full text of the comments may be found in the docket for this action. We have summarized the comments and provided our responses in section II. of this preamble.

II. Comments and Responses

Comment 1 and EPA Responses

The first commenter conveyed overall support for the EPA's proposed action to approve the submitted revisions to the Oregon SIP. The EPA acknowledges the commenter's support for the EPA's approval of Oregon's SIP submission. However, the same commenter also expressed concern about two specific items in our proposed action. First, the commenter speculated about the potential impact to the permitting program and its transparency if the permit fee table (listing the specific dollar amounts charged to facility owners and operators for various types of permit actions) were removed from the SIP. The permit fee table in question is table 2 of Oregon Administrative Rules (OAR) 340-216-8020.

In response to the comment, the EPA reiterates what was stated in the proposed action ^[1] and further elaborates. In the March 27, 2023, submission, Oregon requested to remove the permit fee table from the SIP. The table codifies in State regulation the specific amounts to be charged by the State of Oregon to facility owners and operators for various types of permit actions. This table is revised periodically by the State to account for inflation and State-initiated revenue adjustments. However, there is no Clean Air Act requirement to include this itemized list in the SIP. States may decide to maintain such provisions as State-only regulations. Importantly, the requirement to pay pre-construction permit fees remains in the SIP, consistent with Clean Air Act section 110(a)(2)(L).^[2] Therefore, the EPA's position remains that the SIP submission meets Clean Air Act requirements.

With respect to transparency, the table of permit fees remains codified as a matter of State law in the OAR and is readily available to the public and regulated entities on the Oregon Secretary of State website.^[3] The Oregon Department of Environmental Quality continues to implement the permitting program and charge the associated fees listed in the permit fee table, as required. Therefore, we find that there is no anticipated impact to transparency.

Second, the same commenter expressed concern about removing text from the SIP-approved Oregon rules that historically tightened opacity limits related to visible emissions. While the commenter did not cite to the specific regulation change, we infer that the commenter was referring to the changes to OAR 340-208-0110.

In response to this comment, the EPA believes the commenter has misunderstood Oregon's rule revisions and the basis of the EPA's proposed action. As part of the March 27, 2023 SIP submission, Oregon submitted revisions to OAR 340-208-0110. The revisions removed obsolete text that, in the past, phased in tighter, 20 percent opacity limits starting on January 1, 2020. These tighter, 20 percent opacity limits have been fully phased in and are now widely applicable. Therefore, the text that allowed greater than 20 percent opacity prior to January 1, 2020, is obsolete. Removing this obsolete text from the SIP makes the rules clearer and easier to implement and has no substantive impact on the opacity standards in Oregon's SIP. Therefore, approval of this revision is appropriate.

Comment 2 and EPA Responses

The second commenter stated that they do not feel Oregon does enough to protect the public from air pollution and that the efforts the State does make are not equitable or fair. As an example, the commenter referenced the motor vehicle inspection and maintenance program that requires emissions testing in Portland and other metropolitan areas, but does not require such testing statewide.

The EPA acknowledges the comment, however, the commenter does not indicate with specificity why approval of Oregon's revisions to its SIP-approved permitting rules is inconsistent with the Clean Air Act or otherwise inappropriate.

In addition, the EPA does not consider comments on the SIP-approved Oregon motor vehicle inspection and maintenance program to be within the scope of this action. Revisions to the inspection and maintenance program requirements of Division 256 in the OAR were most recently approved by the EPA on July 12, 2022 and we are not in this action revisiting our prior decision (87 FR 41256). Likewise, comments on potential future changes to the SIP-approved motor vehicle inspection and maintenance program that have not been submitted to the EPA for SIP approval are outside the scope of this action.

Comment 3 and EPA Responses

The third commenter expressed concern about air emissions from cannabis farms and urged that Federal charges be reestablished. The commenter pointed to studies of the potential for volatile organic compound emissions from cannabis farms to contribute to ozone formation. The EPA acknowledges the comment, however, the comment is outside the scope of this action and does not indicate that the EPA's approval of the SIP submission is inconsistent with the CAA. Federal oversight of cannabis farms is unrelated to this action. This action addresses changes to the Oregon regulations governing stationary source permitting in the State, including changes to eliminate generic plant site emission limits, update construction notification requirements, clarify the use of ( printed page 59612) modeling and monitoring for compliance assurance, and streamline the permit application process.

Comment 4 and EPA Responses

The fourth commenter appears to support the EPA's proposed action. The EPA acknowledges the commenter's support of the EPA's approval of Oregon's SIP submission.

For the reasons stated in our proposed action (89 FR 22363, April 1, 2024) and in section II. of this preamble, the EPA is finalizing its action as proposed.

IV. Incorporation by Reference

In this document, the EPA is finalizing regulatory text that includes incorporation by reference. In accordance with requirements of 1 CFR 51.5, we are finalizing the incorporation by reference of the Oregon regulatory provisions described in section III. of this preamble and set forth in the amendments to 40 CFR part 52 in this document. 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 final rule of the EPA's approval, and will be incorporated by reference in the next update to the SIP compilation.^[5]

Also in this document, the EPA is removing regulatory text from incorporated by reference, as described in section III. of this preamble.

V. Statutory and Executive Order Reviews

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 ( printed page 59614) 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 14094 (88 FR 21879, April 11, 2023);
• 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 subject toExecutive Order 13045 (62 FR 19885, April 23, 1997) because it approves a State program;
• Is not a significant regulatory action subject toExecutive Order 13211 (66 FR 28355, May 22, 2001); and
• 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.

Executive Order 12898 (Federal Actions to Address Environmental Justice in Minority Populations and Low-Income Populations, 59 FR 7629, February 16, 1994) directs Federal agencies to identify and address “disproportionately high and adverse human health or environmental effects” of their actions on minority populations and low-income populations to the greatest extent practicable and permitted by law. The EPA defines environmental justice (EJ) as “the fair treatment and meaningful involvement of all people regardless of race, color, national origin, or income with respect to the development, implementation, and enforcement of environmental laws, regulations, and policies.” The EPA further defines the term fair treatment to mean that “no group of people should bear a disproportionate burden of environmental harms and risks, including those resulting from the negative environmental consequences of industrial, governmental, and commercial operations or programs and policies.”

The air agency did not evaluate environmental justice considerations as part of its SIP submission; the Clean Air Act and applicable implementing regulations neither prohibit nor require such an evaluation. The EPA did not perform an EJ analysis and did not consider EJ in this action. Due to the nature of this action, it is expected to have a neutral to positive impact on the air quality of the affected area. Consideration of EJ is not required as part of this action, and there is no information in the record inconsistent with the stated goal of Executive Order 12898 of achieving environmental justice for people of color, low-income populations, and Indigenous peoples.

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 it 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 September 23, 2024. 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).

For the reasons set forth in the preamble, the EPA amends 40 CFR part 52 as follows:

89 FR 59610
