SRCAA submitted this State Plan to fulfill its requirements under the CAA in response to the EPA's May 10, 2006, promulgation of Emissions Guidelines and Compliance Times for Large MWC Constructed on or before September 20, 1994 (Emission Guidelines). The EPA is partially approving the State Plan because it meets the requirements of the Emission Guidelines for existing large MWC known to operate in Spokane County, Washington. The EPA is partially disapproving the State Plan because it omits requirements for fluidized bed combustors and air curtain incinerators, which are required elements of a State Plan. This action is being taken under the CAA. </SUM> <EFFDATE> <HD SOURCE="HED">DATES:</HD> This rule is effective on January 27, 2025.

Proposed Action</HD> On December 13, 2023 (88 FR 86312), the EPA proposed to approve a section 111(d) State Plan submitted by the SRCAA on July 18, 2022, for existing large municipal waste combustors. SRCAA's submitted State Plan was in response to the May 10, 2006, promulgation of the amended emission guidelines (EG) requirements for Large MWC, 40 CFR part 60, subpart Cb (71 FR 27324). Included within the State Plan are regulations under SRCAA Regulation I, Article VI, Section 6.17, entitled “Standards for Municipal Solid Waste Combustors,” effective July 7, 2022. On July 18, 2022, SRCAA submitted the State Plan. We proposed to partially approve this plan because we determined that it complies with the relevant CAA requirements, except requirements applicable to fluidized bed combustors and air curtain incinerators. Because these requirements were omitted, we also proposed to partially disapprove the State Plan submittal. Our proposed action contains more information on the plan and our evaluation. <HD SOURCE="HD1">II. Public Comments and EPA Responses</HD> The EPA's proposed action provided a 30-day public comment period. During this period, we received no comments. <HD SOURCE="HD1">III. EPA Action</HD> For the reasons discussed in our proposed rulemaking and in this action, we are finalizing the partial approval and partial disapproval of SWCAA's State Plan for large MWC, which includes SRCAA Regulation I, Article VI, Section 6.17, effective July 7, 2022. Upon the effective date of this action, SWCAA's State Plan will apply to designated large MWC, as defined in 40 CFR 60.32b, in Spokane County, Washington, with the exception of fluidized bed combustors and air curtain incinerators, which will remain subject to Federal Plan requirements under 40 CFR part 62, subpart FFF. We are finalizing this approval because we have determined the State Plan meets the applicable requirements under 40 CFR part 60, subparts B and Cb, except for the requirements noted as the basis for our partial disapproval above. <HD SOURCE="HD1">IV. Incorporation by Reference</HD> In accordance with the requirements of 1 CFR 51.5, the EPA is finalizing regulatory text that includes the incorporation by reference of SRCAA Regulation I, Article VI, Section 6.17, “Standards for Municipal Solid Waste Combustors” with an effective date of July 7, 2022. These regulatory provisions are part of the CAA State Plan applicable to existing Large MWC in Spokane County, Washington as discussed in Section I of this preamble. They establish requirements related to emission limitations, compliance times, testing, monitoring, reporting, and recordkeeping applicable to Large MWC in Spokane County, Washington that commenced construction on or before September 20, 1994. These provisions set forth requirements meeting criteria required by the amended Emissions Guidelines for existing Large MWC codified at 40 CFR part 60, subpart Cb. The EPA has made, and will continue to make, the entire SRCAA State Plan, generally available through <E T="03">https://www.regulations.gov,</E> Docket No. EPA-R10-OAR-2023-0224, and at the EPA Region 10 Office (please contact the person identified in the <E T="02">FOR FURTHER INFORMATION CONTACT</E> section of this preamble for more information). This incorporation by reference has been approved by the Office of the Federal Register, and the State Plan is Federally enforceable under the CAA as of the effective date of this final rule. <HD SOURCE="HD1">V. Statutory and Executive Order Reviews</HD> In reviewing State Plan submissions, the 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 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 <E T="03">et seq.</E> ); • 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 <E T="03">et seq.</E> ); • 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); 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 CAA. 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 communities with environmental justice (EJ) concerns to the greatest extent practicable and permitted by law. Executive Order 14096 (Revitalizing Our Nation's Commitment to Environmental Justice for All, 88 FR 25251, April 26, 2023) builds on and supplements Executive Order 12898 and defines EJ as, among other things, the just treatment and meaningful involvement of all people, regardless of income, race, color, national origin, or Tribal affiliation, or disability in agency decision-making and other Federal activities that affect human health and the environment.” The air agency did not evaluate environmental justice considerations as part of its submittal; 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 communities with EJ concerns.
