Start Preamble

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule.

SUMMARY:

The Environmental Protection Agency (EPA) is proposing to approve a Clean Air Act (CAA or the “Act”) section 111(d) state plan submitted by the Colorado Department of Public Health and Environment (CDPHE or the “Department”) on March 23, 2021. This state plan was submitted to fulfill the requirements of the CAA and is responsive to the EPA's promulgation of Emission Guidelines and Compliance Times (EG) for existing municipal solid waste (MSW) landfills. The Colorado state plan establishes performance standards and other operating requirements for existing MSW landfills within the State of Colorado and provides for the implementation and enforcement of those standards and requirements by the Department.

I. Background

On August 29, 2016, the EPA finalized revised Standards of Performance (NSPS) for new MSW landfills and EG for existing MSW landfills in 40 CFR part 60, subparts XXX and Cf, respectively. See 81 FR 59331 and 59313. These rulemaking actions were taken in accordance with section 111 of the CAA. Section 111(d) of the Act requires the EPA establish procedures for a state to submit a plan to the Agency that establishes standards of performance for any 'existing' source 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 new source performance standard under section 111(b) would apply if such existing source were a ‘new' source. The EPA established general provisions for submittal of state plans for 111(d) sources in 40 CFR part 60, subpart B. State plan submittals for 111(d) sources must be consistent with the requirements of these general provisions and also establish performance standards and other requirements at least as stringent as those established by the relevant EG as published in 40 CFR part 60. Upon state plan submittal, the EPA reviews a state's plan for consistency with the requirements of the general provisions and specific EG. If the state plan is complete and approvable with reference to these requirements, the Agency notifies the public, promulgates the plan in 40 CFR part 62 and delegates implementation and enforcement of the standards and requirements of the EG to the state under the terms of the state plan as published in the CFR. Today's Start Printed Page 35045action concerns the completeness and approvability of Colorado's 111(d) state plan for existing MSW landfills.

II. Summary and Analysis of the Plan Submittal

The Executive Director of CDPHE submitted a final 111(d) state plan for existing MSW landfills on March 23, 2021 in response to the August 29, 2016 finalization of the revised EG published at 40 CFR part 60, subpart Cf. The EPA has reviewed the Colorado plan submittal in the context of the plan completeness and approvability requirements found in 40 CFR part 60, subparts B and Cf, as well as the general provisions for plan approval found in 40 CFR part 62, subpart A. The EPA is proposing with this action to approve Colorado's submittal. If EPA finalizes the proposed action in a future final rulemaking, EPA will promulgate the plan under 40 CFR part 62, subpart G.

The Colorado state plan submittal package includes all materials necessary to be deemed administratively and technically complete according to the criteria of 40 CFR part 60, subpart B. Colorado has chosen to author a state plan document (the “111(d) Plan for Existing Municipal Solid Waste Landfills in Colorado”) and provide all implementation and enforcement authority for all state plan requirements through revisions to the Code of Colorado Regulations (CCR). Specifically, the State has appropriately incorporated all general EG performance standards and other source requirements in 5 CCR 1001-8 and has given more specific instruction to designated facilities within the state plan document. Both the adopted state plan document and the relevant CCR section, as well as all other relevant plan submittal materials may be found in the docket for today's action. Necessary State legal and enforcement authorities required for plan approval are located elsewhere in Colorado statute, rules and regulations and have been reviewed and approved of by the EPA in the course of prior section 111(d) or 111(d)/129 state plan approvals. See 40 CFR 62.1350-1400. Following the EPA's review of the submittal materials, the Agency finds the state plan package to be approvable according to all plan requirements.

Analysis of the submitted state plan's completeness and approvability, with reference to the relevant general and source category specific plan requirements of 40 CFR part 60, subparts B and Cf, and a detailed explanation of the rationale supporting this proposed approval is available in the Technical Support Document (TSD) in the docket of this proposed rule.

III. Proposed Action

The EPA is proposing to approve the Colorado section 111(d) state plan for MSW landfills. The state plan was submitted in full compliance with the requirements of 40 CFR part 60, subparts B and Cf. Therefore, the EPA is proposing to amend 40 CFR part 62, subpart G to reflect this approval action. This approval is based on the rationale provided in section II of this preamble and discussed in detail in the TSD associated with this rulemaking action. The Agency's approval is in accordance with the general provisions of plan approval found in 40 CFR part 60, subpart B and in part 62, subpart A of that Title and is pursuant to the Agency's role under 42 U.S.C. 7411(d). The EPA's proposed approval of the Colorado plan is limited to those landfills that meet the criteria established in 40 CFR part 60, subpart Cf and grants the State authority to implement and enforce the performance standards and source requirements of the EG, except in those cases where authorities are specifically reserved for the EPA Administrator or his designee. Authorities retained by the EPA Administrator are those listed in 40 CFR 60.30f(c)

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 CDPHE and Colorado Air Quality Control Commission regulations regarding MSW landfills discussed in section II of this preamble. The EPA has made, and will continue to make, these materials available through the docket for this action, EPA-R08-OAR-2021-0004, at https://www.regulations.gov and at the EPA Region 8 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

Under the CAA, the Administrator is required to approve a 111(d) state plan submittal that complies with the provisions of the Act and applicable Federal regulations. 42 U.S.C. 7411(d); 40 CFR 62.02(a). Thus, in reviewing 111(d) plan submittals, the EPA's role is to approve state choices, provided that they meet the criteria of the CAA and the relevant provisions of 40 CFR part 60. Accordingly, this action merely proposes to approve 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 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 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, the Colorado 111(d) state plan for existing MSW landfills is not approved to apply on any Indian reservation land or in any other area where EPA or an Indian tribe has demonstrated that a tribe has jurisdiction. In those areas of Indian country, the proposed 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).
