The Environmental Protection Agency (EPA) is proposing to approve a state plan submitted by the State of Arizona. This state plan submittal pertains to the regulation of landfill gas and its components, including methane, from existing municipal solid waste (MSW) landfills. Arizona's state plan was submitted in response to the EPA's promulgation of Emissions Guidelines and Compliance Times for MSW landfills. This action is being taken under the Clean Air Act (CAA).

SUPPLEMENTARY INFORMATION:

I. Background

On August 29, 2016, the EPA finalized Standards of Performance for Municipal Solid Waste Landfills and Emission Guidelines and Compliance Times for Municipal Solid Waste Landfills in 40 CFR part 60 subpart XXX and Cf, respectively. 81 FR 59332 and 81 FR 59276. These actions were taken under section 111 of the CAA.

Section 111(d) of the CAA requires the EPA to establish a procedure for a state to submit a plan to the EPA which establishes standards of performance for any air pollutant: (1) For which air quality criteria have not been issued or which is not included on a list published under CAA section 108 or emitted from a source category which is regulated under CAA section 112 but (2) to which a standard of performance under CAA section 111 would apply if such existing source were a new source. The EPA established the requirements for state plan submittals in 40 CFR part 60, subpart B. State submittals under CAA sections 111(d) must be consistent with the relevant emission guidelines, in this instance 40 CFR part 60, subpart Cf, and the requirements of 40 CFR part 60, subpart B.

On July 24, 2018, the Arizona Department of Environmental Quality (ADEQ) submitted to the EPA a formal section 111(d) plan for existing municipal solid waste landfills. The submitted section 111(d) plan was in response to the August 29, 2016 promulgation of federal NSPS and emission guidelines requirements for MSW landfills, 40 CFR part 60, subparts XXX and Cf, respectively (81 FR 59332 and 81 FR 59276) 76 FR 15372).

II. Summary of the Plan and EPA Analysis

The EPA has reviewed the Arizona section 111(d) plan submittal in the context of the requirements of 40 CFR part 60, subparts B and Cf, and part 62, subpart A. In this action, the EPA is proposing to determine that the submitted section 111(d) plan meets the above-cited requirements. The primary mechanism selected by ADEQ to implement the emission guidelines for MSW landfills under state jurisdiction is through incorporation by reference of 40 CFR part 60, subpart Cf and 40 CFR part 60, subpart XXX into the Arizona Administrative Code (A.A.C.), at A.A.C. R18-2-731, entitled “Standards of Performance for Existing Municipal Solid Waste Landfills,” and A.A.C. R18-2-901(79), entitled “New Source Performance Standards,” on July 6, 2018. These subparts will be applicable to MSW landfills under the plan upon the EPA's approval of the plan by final rulemaking. A detailed explanation of the rationale behind this proposed approval is available in the Technical Support Document (TSD).

III. Proposed Action

The EPA is proposing to approve the Arizona section 111(d) plan for MSW landfills submitted pursuant to 40 CFR part 60, subpart Cf. Therefore, the EPA is proposing to amend 40 CFR part 62, subpart D, to reflect this action. This approval is based on the rationale previously discussed and in further detail in the TSD associated with this action. The scope of the proposed approval of the section 111(d) plan is limited to the provisions of 40 CFR parts 60 and 62 for existing MSW landfills, as referenced in the emission guidelines, subpart Cf.

IV. Incorporation by Reference

In this document, the EPA is proposing to include in a final EPA rule regulatory text that includes incorporation by reference of the state plan. In accordance with requirements of 1 CFR 51.5, the EPA is proposing to incorporate by reference ADEQ rules regarding MSW landfills discussed in section II of this preamble. The EPA has made, and will continue to make, these materials generally available through http://www.regulations.gov, Docket ID No. EPA-R09-OAR-2019-0344, and at the EPA Region IX Office (please contact the person identified in the “For Further Information Contact” section of this preamble for more information).

V. Statutory and Executive Order Reviews

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 proposed 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 an Executive 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, as described in the Unfunded Mandates Reform Act of 1995 (Public Law 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 the 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 proposed approval of Arizona's state plan submittal for existing MSW landfills does not have tribal implications as specified by Executive Order 13175 (65 FR 67249, November 9, 2000), because the state plan is not approved to apply in Indian country located in the state, and the Start Printed Page 32365EPA notes that it will not impose substantial direct costs on tribal governments or preempt tribal law.
