 Background
Section 129 of the Clean Air Act (CAA) directs the EPA to establish performance standards and other requirements for each category of solid waste incineration units. Subsection (a)(1)(D) specifically provides for the establishment of performance standards for commercial and industrial solid waste incineration (CISWI) units. The EPA is directed by this subsection to establish performance standards, guidelines and other requirements for each category of `existing' CISWI units under the authority of both sections 129 and 111(d) of the Act. Upon promulgation of such performance standards and guidelines, states with existing designated facilities operating within their jurisdiction are to submit for EPA approval a section 111(d)/129 state plan to implement and enforce standards at least as stringent as those established by the EPA emission guidelines for existing units. 
The federal emission guidelines and requirements for existing CISWI units are codified at 40 CFR part 60, subpart DDDD, "Emissions Guidelines and Compliance Times for Commercial and Industrial Solid Waste Incineration Units." On July 14, 2017, the Colorado Department of Public Health and Environment (CDPHE) formally submitted a new CAA section 111(d)/129 State plan (the "plan") to the Region 8 EPA office for the regulation of existing CISWI units. This submittal rescinds Colorado's present negative declaration, certifying an absence of CISWI units within the state's jurisdiction, and replaces it with a plan implementing statewide control and oversight of existing CISWI units. The present negative declaration was approved and promulgated by the EPA on September 17, 2000, at 40 CFR part 62, subpart G (68 FR 54373). The current submittal intends to fulfill Colorado's plan development requirement following the EPA's May 18, 2011 revision of the CISWI rule (76 FR 15704) and the subsequent February 2013 and June 2016 final actions on reconsideration of the rule. This document will assess the approvability of the new CISWI State plan, and associated state rulemaking acceptability with respect to the federal requirements for CISWI 111(d)/129 State plan submittals.
The approval of section CISWI 111(d)/129 State plans is meant to continue improvements in the control of certain air pollutants originating from CISWI units through the requirement of more stringent pollutant controls at a facility level. The target air pollutants are: dioxins/furans, carbon monoxide, metals (cadmium, lead and mercury), particulate matter, hydrogen chloride, sulfur dioxide, oxides of nitrogen, fugitive ash and opacity. An explanation of the impacts of 111(d)/129 State plan implementation for existing CISWI units nationwide, including primary air impacts, secondary air impacts, water and solid waste impacts, energy impacts and cost and economic impacts may be found in "Section VI" of the preamble to the March 21, 2011 final NSPS and EG final rule (76 FR 15704).
II. Federal Requirements for an Approvable Colorado CISWI Plan
The revised Colorado plan for existing CISWI units must meet three sets of federal requirements: 1) The general requirements for developing and processing 111(d) plans found in 40 CFR part 60, subpart B, sections 60.23  -  60.26, excepting the provisions for electric generating units; 2) State plan requirements found in 40 CFR part 60, subpart DDDD; and 3) the pertinent requirements of 40 CFR part 62, subpart A. An approvable state plan submittal meets all of these requirements through revisions to state rules for new and existing CISWI units and by including certain facility requirements in the state plan document itself. The relevant state rule in this case is found in the Code of Colorado Regulations, Regulation Number 6 (5 CCR 1001-8) Part A. Legal authority to implement the state plan is primarily demonstrated in the provisions of the Colorado Revised Statutes (CRS), Title 25. The Colorado State plan document is specifically drafted to address emissions from existing CISWI units as defined under 40 CFR 60, subpart DDDD. The state plan submittal package under review here contains: 
1. The Colorado State plan document, including requirements for existing CISWI units referencing the most recent revisions to 40 CFR part 60, subpart DDDD, and reference to the most recent revisions to the Code of Colorado Regulations and the pertinent sections of the Colorado Revised Statutes demonstrating legal authority to implement and enforce the plan.
2. Documentation and certification of public notice of rulemaking and public participation activities.
3. A copy of the pertinent revised state rule, certified by the Colorado State Attorney General, demonstrating CDPHE legal authority to regulate CISWI units in the State of Colorado.
A summary of the Colorado plan's completeness and approvability in the context of 40 CFR part 60, subparts B and DDDD is given in the following section.
III. Completeness and Approvability Review
A completeness and approvability review of the "111(d) Plan for Commercial and Industrial Solid Waste Incineration Units (that commenced construction on or before November 30, 1999)" as submitted by the CDPHE Air Pollution Control Division has been completed prior to proposal of plan approval by the EPA. The completeness and approvability review includes: (1) a review of the plan's fulfillment of requirements under 40 CFR 60, subpart DDDD [Appendix A]; (2) a review of the plan's fulfillment of requirements under 40 CFR 60, subpart B [Appendix B]; and, (3) a review of the plan's demonstration of the CDPHE's legal authority to regulate CISWI facilities [Appendix C].
IV. Conclusion
The EPA's review of the CDPHE Colorado State plan submittal for existing CISWI units finds the plan consistent with 40 CFR part 60, subpart B and subpart DDDD, and 40 CFR part 62, subpart A. The EPA is therefore proposing to approve the plan and amend 40 CFR part 62, subpart G to reflect this approval and thereby bring the state plan into effect. Upon the final effective date of the approved plan, the EPA Administrator will retain several authorities, including the authorities specifically associated with the "EPA Administrator" in the Subpart DDDD `Model Rule'. The State of Colorado will assume responsibility for enforcement of the requirements under the current emission guidelines for existing CISWI units.

§60.24 Emission standards and compliance schedules.

(a) Each plan shall include emission standards and compliance schedules.
CO State plan mandates the CISWI model rule emission and operating limits specified in subpart DDDD 60.2670- 60.2680. Tables from subpart DDDD including emission limits for units after the final compliance date are included in either the plan, or 40 CFR part 60, subpart DDDD as it is incorporated in the state rule.
(b) (1) Emission standards shall either be based on an allowance system or prescribe allowable rates of emissions except when it is clearly impracticable. Such cases will be identified in the guideline documents issued under §60.22. Where emission standards prescribing equipment specifications are established, the plan shall, to the degree possible, set forth the emission reductions achievable by implementation of such specifications, and may permit compliance by the use of equipment determined by the state to be equivalent to that prescribed.
Not applicable
(2) Test methods and procedures for determining compliance with the emission standards shall be specified in the plan. Methods other than those specified in appendix A to this part may be specified in the plan if shown to be equivalent or alternative methods as defined in §60.2 (t) and (u).
The testing methods outlined in the Subpart DDDD Model Rule and specified in 40 CFR part 60, appendix A are incorporated by reference in the state rule and indicated in the state plan.
(3) Emission standards shall apply to all designated facilities within the state. A plan may contain emission standards adopted by local jurisdictions provided that the standards are enforceable by the state.
Not applicable
(c) Except as provided in paragraph (f) of this section, where the Administrator has determined that a designated pollutant may cause or contribute to endangerment of public health, emission standards shall be no less stringent than the corresponding emission guideline(s) specified in subpart C of this part, and final compliance shall be required as expeditiously as practicable but no later than the compliance times specified in subpart C of this part.
Final compliance date of February 7, 2018, is set in both Subpart DDDD, as incorporated into the state rule, and the state plan.
(d) Where the Administrator has determined that a designated pollutant may cause or contribute to endangerment of public welfare but that adverse effects on public health have not been demonstrated, states may balance the emission guidelines, compliance times, and other information provided in the applicable guideline document against other factors of public concern in establishing emission standards, compliance schedules, and variances. Appropriate consideration shall be given to the factors specified in §60.22(b) and to information presented at the public hearing(s) conducted under §60.23(c).
Not applicable
(e)(1) Any compliance schedule extending more than 12 months from the date required for submittal of the plan must include legally enforceable increments of progress to achieve compliance for each designated facility or category of facilities. Unless otherwise specified in the applicable subpart, increments of progress must include, where practicable, each increment of progress specified in §60.21(h) and must include such additional increments of progress as may be necessary to permit close and effective supervision of progress toward final compliance.
Not applicable  -  Subpart DDDD requirements apply instead of section 60.24(e)(1) [Section 60.2540(b)]

Not applicable
(f) Unless otherwise specified in the applicable subpart on a case-by-case basis for particular designated facilities or classes of facilities, states may provide for the application of less stringent emissions standards or longer compliance schedules than those otherwise required by paragraph (c) of this section, provided that the state demonstrates with respect to each such facility (or class of facilities):
Not applicable  -  Subpart DDDD requirements for final compliance dates and emission standards apply; No allowance for case-by-case judgements on less stringent emission standards and longer compliance schedules [Section 60.2540(a) see: comment on 60.24(c)]
(1) Unreasonable cost of control resulting from plant age, location, or basic process design;
Not applicable
(2) Physical impossibility of installing necessary control equipment; or
Not applicable
(3) Other factors specific to the facility (or class of facilities) that make application of a less stringent standard or final compliance time significantly more reasonable.
Not applicable
(g) Nothing in this subpart shall be construed to preclude any state or political subdivision thereof from adopting or enforcing (1) emission standards more stringent than emission guidelines specified in subpart C of this part or in applicable guideline documents or (2) compliance schedules requiring final compliance at earlier times than those specified in subpart C or in applicable guideline documents.
Not applicable  -  Subpart DDDD Model Rule provisions for emission standards and compliance schedules has been fully incorporated into Colorado Code of Regulations.
