SUPPLEMENTARY INFORMATION:

Throughout this document “we,” “us,” and “our” means the EPA.

I. Background

The background for this action is discussed in detail in our March 26, 2021 proposed rule (86 FR 16173). In that document we proposed to approve the North Dakota CAA section 111(d) state plan for existing MSW landfills and the North Dakota CAA section 111(d)/129 state plan for existing CISWI units as the plans were submitted by the NDDEQ on July 28, 2020. That document also proposed approval of the North Dakota withdrawal of a previously approved CAA section 111(d)/129 state plan for existing HMIWI units and publication of the State's negative declaration of existing HMIWI units in lieu of a state plan. The EPA's analysis of the two North Dakota state plans and the negative declaration of designated sources may be found in the aforementioned proposed rule and the technical support document (TSD) associated with the docket for today's action. Comments on the EPA's proposed approvals of the state plans for existing CISWI units and MSW landfills and approval of the negative declaration in lieu of a state plan for existing HMIWI units were due on or before April 26, 2021. We received no comments on our proposed actions. Therefore, the EPA will proceed with these plan approvals without changes.

II. Final Action

The EPA is finalizing approval of the North Dakota section 111(d) state plan for existing MSW landfills pursuant to 40 CFR part 60, subparts B and Cf. We are also finalizing approval of the North Dakota section 111(d)/129 state plan for existing CISWI units pursuant to 40 CFR part 60, subparts B and DDDD. Finally, we are finalizing approval of the State's negative declaration of existing HMIWI units in lieu of a state plan for such units as designated by 40 CFR part 60, subpart Ce. Therefore, the EPA is amending 40 CFR part 62, subpart JJ to reflect this approval action. This approval is based on the rationale provided in section II of the proposed rule for this action (86 FR 16173) and discussed in detail in the TSD associated with this rulemaking action.^[1] The scope of this approval is limited to the provisions of 40 CFR parts 60 and 62. The EPA's proposed approval of the two North Dakota plans is limited to those MSW landfills that meet the criteria established in 40 CFR part 60, subparts Cf and those CISWI units and ACI units that meet the criteria ( printed page 35407) established in 40 CFR part 60, subpart DDDD.

The EPA Administrator continues to retain authority for approval of alternative methods to determine the nonmethane organic compound concentration or a site-specific methane generation rate constant (k), as stipulated in 40 CFR 60.30f(c). The EPA Administrator also retains those authorities related to designated CISWI and ACI units that will not be delegated to state, local or tribal authorities as listed in 40 CFR 60.2542.

III. Incorporation by Reference

In accordance with the requirements of 1 CFR 51.5, we are finalizing regulatory text that includes the incorporation by reference of subparts Cf and DDDD of chapter 33.1-15-12, section 2 of the North Dakota Administrative Code (NDAC) as effective on July 1, 2020. Subparts Cf and DDDD are part of the North Dakota CAA section 111(d) state plan applicable to existing MSW landfills and the section 111(d)/129 state plan for existing CISWI units, respectively. The regulatory provisions of these sections of the NDAC incorporate the required 111(d) and 111(d)/129 state plan elements required by the emission guidelines (EG) for existing MSW landfills and CISWI units promulgated at 40 CFR part 60, subparts Cf and DDDD. The incorporations establish emission standards and compliance times for the control of air pollutants from certain MSW landfills that commenced construction, modification, or reconstruction on or before July 17, 2014 and designated CISWI and ACI units that commenced construction on or before June 4, 2010 or commenced modification or reconstruction no later than August 7, 2013. The emissions standards and compliance times established within these NDAC sections and the North Dakota state plans are at least as stringent as those required by the EG for existing MSW landfills and CISWI units. The EPA has made, and will continue to make, NDAC section 33.1-15-12-02 (as well as the North Dakota state plan documents for existing MSW landfills and CISWI units) generally available electronically through www.regulations.gov, Docket No. EPA-R08-OAR-2021-0187 and in hard copy at the EPA Region 8 office (please contact the person identified in the FOR FURTHER INFORMATION CONTACT section of this preamble for more information). This incorporation by reference has been approved by the Office of the Federal Register and the Plans are federally enforceable under the CAA as of the effective date of this final rulemaking.

IV. Statutory and Executive Order Reviews

Under the Clean Air Act, the Administrator is required to approve section 111(d) state plan submissions that comply with the provisions of the Act and applicable Federal regulations. 42 U.S.C. 7411(d); 40 CFR part 60, subparts B, Cf and DDDD; and 40 CFR part 62, subpart A. Thus, in reviewing CAA section 111(d) state plan submissions, the EPA's role is to approve state choices, provided that they meet the criteria of the Act and implementing regulations. 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);
• Is not anExecutive Order 13771 (82 FR 9339, February 2, 2017) regulatory action because this action is not significant under Executive Order 12866;
• 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, 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 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, underExecutive Order 12898 (59 FR 7629, February 16, 1994).

In addition, the CAA section 111(d) Plans are not approved to apply in Indian country, as defined at 18 U.S.C. 1151, located in the state. As such, this rule does not have tribal implications, as specified by Executive Order 13175 (65 FR 67249, November 9, 2000), and it will not impose substantial direct costs on tribal governments or preempt tribal law.

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 September 7, 2021. 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).)
