2021 Colorado Code|Title 25 - Public Health and Environment|Article 7 - Air Quality Control|Part 1 - Air Quality Control Program|§ 25-7-105. Duties of Commission - Rules - Legislative Declaration - Definitions

  Except as provided in sections 25-7-130 and 25-7-131, the commission shall promulgate rules that are consistent with the legislative declaration set forth in section 25-7-102 and necessary for the proper implementation and administration of this article 7, including:     A comprehensive state implementation plan which will assure attainment and maintenance of national ambient air quality standards and which will prevent significant deterioration of air quality, all in conformity with the provisions of this article. The comprehensive plan shall meet all requirements of the federal act and shall be revised whenever necessary or appropriate. (a) (I) A comprehensive state implementation plan which will assure attainment and maintenance of national ambient air quality standards and which will prevent significant deterioration of air quality, all in conformity with the provisions of this article. The comprehensive plan shall meet all requirements of the federal act and shall be revised whenever necessary or appropriate.    The comprehensive state implementation plan of the commission shall, wherever feasible, include local or regional air pollution plans and programs adopted or enforceable by municipal or county governments. Before making any changes to those portions of the state implementation plan which include such air pollution plans and programs or to such plans and programs which are suggested for inclusion in the state implementation plan, the commission shall give thirty days' notice of the proposed changes to the affected municipal or county government to allow a reasonable opportunity to prepare comments on the proposed changes. The commission shall consider such comments in its action on the state implementation plan and shall document in the record of the hearing its reasons for any changes to such plans and programs. Any such plans and programs which are approved by the commission and formally submitted as a part of the state implementation plan shall be deemed a part of the comprehensive program of the commission and shall be enforced as such.    The revisions to the Denver element of the PM-10 state implementation plan adopted by the commission on February 16, 1995, which contain a sixty tons-per-day PM-10 mobile source emissions budget which expires January 1, 1998, and reverts to a forty-four tons-per-day budget, are amended to provide that such forty-four tons-per-day reversion shall not be a part of the state implementation plan and shall only apply as a regulation adopted exclusively under reserved state authority pursuant to the provisions of section 25-7-105.1. The sixty tons-per-day emissions budget shall, unless modified by the commission through rule-making, apply for federal transportation conformity and is included in the state implementation plan only as required by the federal act. Any entity with authority to adopt a transportation plan required under section 43-1-1103, C.R.S., shall consider any mobile source emissions budgets in effect under this article in the development of transportation improvement programs for federal purposes.    Notwithstanding the provisions of section 25-7-133, the expiration of the state implementation plan for ozone maintenance and related rules of the air quality control commission, and the amendments to commission regulations number 3 and 7, which state implementation plan and rules, and amendments to regulations number 3 and 7, were adopted or amended by the commission on March 21, 1996, and which are therefore scheduled for expiration May 15, 1997, is postponed until December 31, 2005, and the provisions of section 24-4-108, C.R.S., shall apply.       Emission control regulations in conformity with section 25-7-109;    A prevention of significant deterioration program in conformity with part 2 of this article and federal requirements; except that definitions used in the program shall not differ from any definitions pertaining to the prevention of significant deterioration program which appear in section 169 of the federal act or in federal regulations promulgated thereunder, and an attainment program in conformity with part 3 of this article;    A satisfactory process of consultation with general purpose local governments and any federal land manager having authority over federal land to which the state implementation plan applies, effective with respect to measures adopted after August 7, 1978, pertaining to transportation controls, air quality maintenance plan requirements, preconstruction review of stationary sources of air pollution, or any measure referred to in the prevention of significant deterioration program established pursuant to part 2 of this article or the attainment program established pursuant to part 3 of this article, or granting delayed compliance orders pursuant to section 25-7-118.  (d.5) Additional permitting requirements for sources that affect disproportionately impacted communities in conformity with section 25-7-114.4 (5) .       Statewide greenhouse gas pollution abatement. As the commission adopts rules pursuant to this subsection (1)(e), it shall pursue near-term reductions in greenhouse gas emissions as part of the effort to reduce total cumulative emissions over time. (e) (I) Statewide greenhouse gas pollution abatement. As the commission adopts rules pursuant to this subsection (1)(e), it shall pursue near-term reductions in greenhouse gas emissions as part of the effort to reduce total cumulative emissions over time.    Consistent with section 25-7-102 (2)(g), the commission shall timely promulgate implementing rules and regulations. The implementing rules may take into account other relevant laws and rules, as well as voluntary actions taken by local communities and the private sector, to enhance efficiency and cost-effectiveness, and shall be revised as necessary over time to ensure timely progress toward the 2025, 2030, and 2050 goals. The implementing rules shall provide for ongoing tracking of emission sources that adversely affect disproportionately impacted communities and are subject to rules implemented pursuant to this subsection (1)(e) and must include strategies designed to achieve reductions in harmful air pollution affecting those communities.    The commission will identify and engage with disproportionately impacted communities as specified in section 24-4-109.    The division, at the direction of the commission, shall solicit input from other state agencies, stakeholders, and the public on the advantages of different statewide greenhouse gas pollution mitigation measures, specifically soliciting input from those most impacted by climate change, including disproportionately impacted communities; large emission sources; workers in relevant industries, including advanced energy and fuel delivery; and communities that are currently economically dependent on industries with high levels of greenhouse gas emissions.    The implementing rules and policies may include, in addition to renewable energy development strategies, regulatory strategies that have been deployed by another jurisdiction to reduce multi-sector greenhouse gas emissions, that facilitate adoption of technologies that have very low or zero emissions, and that enhance cost-effectiveness, compliance flexibility, and transparency around compliance costs, among other regulatory strategies. The commission may coordinate with other jurisdictions in securing emission reductions, including in satisfying future federal regulations. The commission may account for reductions in net greenhouse gas emissions that occur under coordinated jurisdictions' programs if the commission finds that the implementing regulations of each coordinated jurisdiction are of sufficient rigor to ensure the integrity of the reductions in greenhouse gas emissions to the atmosphere and may account for carbon dioxide that electricity consumption in this state causes to be emitted elsewhere.    In carrying out its responsibilities under this subsection (1)(e), the commission shall consider: The benefits of compliance, including health, environmental, and air quality; the costs of compliance; economic and job impacts and opportunities; the time necessary for compliance; the relative contribution of each source or source category to statewide greenhouse gas pollution based on current data updated at reasonable intervals as determined by the commission; harmonizing emission reporting requirements with existing federal requirements, where the commission deems appropriate; the importance of striving to equitably distribute the benefits of compliance, opportunities to incentivize renewable energy resources and pollution abatement opportunities in disproportionately impacted communities, opportunities to encourage clean energy in transitioning communities; issues related to the beneficial use of electricity to reduce greenhouse gas emissions; whether program design could enhance the reliability of electric service; the potential to enhance the resilience of Colorado's communities and natural resources to climate impacts; and whether greater or more cost-effective emission reductions are available through program design.    Notwithstanding section 24-1-136 (11)(a)(I), the division, at the direction of the commission, shall report to the general assembly every odd-numbered year after May 30, 2019, regarding: Progress toward the goals set forth in section 25-7-102 (2)(g); any newly available, final cost-benefit or regulatory analysis, developed under section 24-4-103 (2.5) or (4.5), for rules adopted to attain the goals; recommendations on future commission rules or policies to reduce greenhouse gas emissions sufficient to achieve the goals set forth in section 25-7-102 (2)(g); and any recommendations on future legislative action to address climate change, including implementation of climate adaptation policies or accelerating deployment of cleaner technologies. The division shall make its proposed report available for public review prior to presentation to the general assembly. Beginning with the report in 2023, if the report indicates that emission reductions required by subsections (1)(e)(XII) and (1)(e)(XIII) of this section are not being met, the division shall develop and propose additional requirements to the commission, no later than six months from the submission of the report to the general assembly, which requirements must address any shortfall between the emission reductions achieved and the emission reductions necessary to meet the requirements of subsections (1)(e)(XII) and (1)(e)(XIII) of this section. In even-numbered years when a report is not made pursuant to this subsection (1)(e)(VII), the division shall provide an update to the commission on progress toward the emission reduction requirements in subsections (1)(e)(XII) and (1)(e)(XIII) of this section based on annual data reported to the division.    (A) In carrying out its responsibilities under this subsection (1)(e), the commission shall consult with the public utilities commission, including on issues of cost of electricity, reliability of electric service, technology developments in electricity production, and beneficial electrification, and keep a record of its consultation. (VIII.5) (A) This subsection (1)(e)(VIII.5)(A) and subsections (1)(e)(VIII.5)(B) and (1)(e)(VIII.5)(C) of this section apply only to an electric utility that serves at least fifty thousand Colorado retail customers and obtains less than eighty percent of the load necessary to serve Colorado retail customers from an electric utility that has filed a clean energy plan and owns or plans to invest in, in whole or in part, an electric generating unit with a nameplate capacity larger than fifty megawatts that directly emits greenhouse gases into the atmosphere, including generating units that burn oil, gas, or coal. The requirements of subsections (1)(e)(VIII.5)(B) and (1)(e)(VIII.5)(C) of this section become applicable if an electric utility satisfies the criteria specified in this subsection (1)(e)(VIII.5)(A) upon leaving a provider who has filed a clean energy plan. The electric utility shall provide notice of intent to file a clean energy plan to the division within six months after becoming subject to this subsection (1)(e)(VIII.5). The electric utility shall file a clean energy plan pursuant to subsection (1)(e)(VIII) of this section within one year after becoming subject to this subsection (1)(e)(VIII.5).    (A) In addressing greenhouse gas emissions from an energy-intensive, trade-exposed manufacturing source, the commission shall require the source to execute an energy and emission control audit, according to criteria established by the commission, of the source's operations every five years through at least 2035. A qualified third party, as determined by the commission, shall conduct the audit and submit the results to the commission. If the commission determines that the source currently employs best available emission control technologies for greenhouse gas emissions and best available energy efficiency practices, the commission shall not impose a direct nonadministrative cost on the source directly associated with at least ninety-five percent of the source's greenhouse gas emissions attributable to manufacturing a good in this state for a period of five years, if the source's emissions are not greater than the emissions associated with use of the best available emission control technologies as determined by the commission. The commission shall consider how program design as relevant to those sources can further mitigate the cost of reducing emissions for such manufacturers while providing an incentive to improve efficiency and reduce emissions. Specifically, the commission shall design the program as relevant to those sources such that as the sources are subject to emission reduction requirements, those sources will have, under the program, a pathway to obtain equivalent lower-cost emission reductions at other regulated sources to satisfy their compliance obligations.    Nothing in this subsection (1)(e) diminishes the existing authority of the commission or the division. Nothing in this subsection (1)(e) alters the regulatory exemptions provided in section 25-7-109 (8)(a). Nothing authorized in this subsection (1)(e), including the assignment of emission reduction obligations or emission authorizations and excluding program development and administrative costs, implicates state fiscal year spending as defined in section 24-77-102. Nothing in this subsection (1)(e) alters any requirement to prepare a cost-benefit analysis under section 24-4-103 (2.5) or any requirement to issue a regulatory analysis under section 24-4-103 (4.5). Nothing in this subsection (1)(e) diminishes the authority of the public utilities commission under the public utilities law, including sections 40-3-101 and 40-3-102.  (X.4) No later than September 1, 2022, the commission shall propose rules establishing recovered methane protocols, as that term is defined in section 40-3.2-108 (2)(q) , for at least inactive coal mines, biomethane as that term is defined in section 40-3.2-108 (2)(a) , and gas system leaks, and a crediting and tracking system for recovered methane as that term is defined in section 40-3.2-108 (2)(o) . The commission shall adopt the rules no later than February 1, 2023. The rule-making proceeding is subject to the procedural requirements of this subsection (1)(e).  (X.7) In designing greenhouse gas emission reduction rules that apply to gas distribution utilities with clean heat plans approved by the public utilities commission, the commission shall harmonize its regulatory requirements with the activities contemplated under an approved clean heat plan. In adopting any additional emission reduction requirements on gas distribution utilities subject to a clean heat plan different from the requirements of an approved clean heat plan, the commission shall:   Consult with the public utilities commission regarding the emission reductions under any approved clean heat plan, the clean heat targets, and the cost-effectiveness of any additional emission reduction requirements and their impact on customer costs; and    Design rules to maximize cost-effectiveness of additional emission reduction requirements to protect low-income customers.  (X.8) (A) The definitions in section 40-3.2-108 (2) apply to this subsection (1)(e)(X.8) and subsection (1)(e)(X.7) of this section.     A municipal gas distribution utility shall submit its clean heat plan to the division no later than August 1, 2023, for the division to verify that the plan demonstrates that, by 2025, the utility will achieve at least a four percent total reduction in greenhouse gas emissions caused by the utility's retail gas sales below 2015 levels, of which not more than one percent can come from recovered methane. The utility may propose a cost cap of two percent of total annual revenue from full-service gas customers in achieving the 2025 target. The plan submitted to the division must also show that, by 2030, the utility will achieve at least a twenty-two percent reduction in greenhouse gas emissions caused by the utility's retail gas sales below 2015 levels by 2030, of which not more than five percent can be from recovered methane. The utility may propose a cost cap of two and one-half percent of total annual revenue from full-service gas customers in achieving the 2030 target. If the division's calculations show that a clean heat plan submitted by a municipal gas distribution utility does not achieve the relevant clean heat targets, the utility shall revise its plan to strive to maximize emission reductions without exceeding the cost cap.    The utility shall provide to the division an annual report of carbon dioxide emissions associated with customer end-uses and, separately, methane emissions associated with the utility's distribution system.       As used in this subsection (1)(e):   “Cost-effective” or “cost-effectiveness” means the cost per unit of reduced emissions of greenhouse gases expressed as carbon dioxide equivalent.    “Greenhouse gas” includes carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons, nitrogen trifluoride, and sulfur hexafluoride, expressed as carbon dioxide equivalent. (B.5) “Industrial and manufacturing sector” means energy combustion and energy use by industry, including: Combustion from coal, diesel, gasoline, heat, liquified petroleum gas, natural gas, refinery feedstocks, and residual fuel oil; and industrial processes, including cement manufacture, electric transmission and distribution equipment, iron and steel production, lime manufacture, limestone and dolomite use, ozone depleting substances substitutes, semiconductor manufacture, soda ash, and urea consumption. The term does not include oil and gas exploration, production, processing, transmission, and storage operations other than energy combustion emissions that are included in the industrial and manufacturing sector.    “Retail electricity sales” means electric energy sold to retail end-use electric consumers.       No later than January 1, 2022, the commission shall adopt, and the division shall begin implementing, comprehensive rules that will reduce statewide greenhouse gas emissions from oil and gas exploration, production, processing, transmission, and storage operations in the state below the 2005 baseline established for the oil and gas emissions covered by the “oil and gas fugitive emissions” category in the initial inventory developed by the division pursuant to section 25-7-140 (2)(a)(II), taking into account subsections (1)(e)(II) to (1)(e)(VI) of this section, by at least thirty-six percent by 2025 and sixty percent by 2030. The commission shall design the rules to prioritize near-term reductions in greenhouse gas emissions. The rules must include:   Protections for disproportionately impacted communities, achieving reduction of greenhouse gases and co-pollutants; and    More robust monitoring, leak detection, and repair requirements, reporting, and record-keeping requirements to ensure that the division can accurately quantify greenhouse gas emissions during all operating conditions, including equipment malfunctions; and    Additional direct emission reduction controls.       In implementing this subsection (1)(e), the commission shall adopt rules to reduce statewide greenhouse gas emissions from the industrial and manufacturing sector in the state by at least twenty percent by 2030 below the 2015 baseline established pursuant to section 25-7-140 (2)(a)(II), taking into account the factors set out in subsections (1)(e)(II) to (1)(e)(VI) of this section. The rules must include protections for disproportionately impacted communities and prioritize emission reductions that will reduce emissions of co-pollutants that adversely affect disproportionately impacted communities, be designed to accelerate near-term reductions, and secure meaningful emission reductions from this sector to be realized beginning no later than September 30, 2024. The rules must:   Be consistent with the requirements of subsection (1)(e)(IX) of this section; and    Require a five percent reduction in the greenhouse gas emissions associated with energy-intensive, trade-exposed manufacturing sources that currently employ best available emission control technologies for greenhouse gas emissions and best available energy efficiency practices, as determined by the commission, pursuant to subsection (1)(e)(IX)(A) of this section.    “Trading program” means a commission-adopted regulatory program that allows for regulated sources to meet their greenhouse gas compliance obligations under subsection (1)(e) of this section through the creation, purchase, acquisition, or exchange of, or other commercial-type transaction involving, a GHG credit with other regulated sources.            Definitions. The definitions in subsection (1)(e)(XI) of this section apply to this subsection (1)(f). As used in this subsection (1)(f), unless the context requires otherwise: (f) (I) Definitions. The definitions in subsection (1)(e)(XI) of this section apply to this subsection (1)(f). As used in this subsection (1)(f), unless the context requires otherwise:    Greenhouse gas accounting system. Except as specified in subsection (1)(f)(III) of this section, before the commission adopts a rule or program that provides for the use of a trading program, the commission shall adopt a rule that directs the division to create a comprehensive and centralized accounting system to track emissions from, at a minimum, all regulated sources in the state covered by or that may otherwise participate in that trading program, which system must:   Enable the division and the public to track emission reductions, trades, and other transactions by sources utilizing GHG credits or otherwise participating in a trading program, and to track any transactions that take place consistent with the requirements set forth in this subsection (1)(f), including all rules promulgated pursuant to this subsection (1)(f);    Enable the division to prevent double counting of greenhouse gas emission reductions; and    Identify regulated sources that adversely affect disproportionately impacted communities through their emissions of locally harmful air pollutants.       The commission may adopt a trading program among regulated sources as necessary to timely implement subsection (1)(e)(IX) of this section if that program:   Is ultimately integrated into the comprehensive and centralized accounting system developed pursuant to subsection (1)(f)(II) of this section;    Enables the division to track the emissions of, and emission reductions, trades, and other transactions by, all regulated sources participating in the trading program;    Enables the division to prevent double counting of greenhouse gas emission reductions; and    Identifies regulated sources that adversely affect disproportionately impacted communities through their emissions of locally harmful air pollutants.          With regard to the changes made in 2021 by House Bill 21-1266:   Nothing:   Alters the greenhouse gas emission reduction goals previously established in section 25-7-102 (2)(g), in either amount or timing; or    Detracts from the air quality control commission's existing authority to require more than the minimum greenhouse gas emission reduction goals and deadlines previously established in section 25-7-102 (2)(g); and       The changes add to, but do not otherwise alter, the air quality control commission's authority and obligation to publish and promulgate rules pursuant to this section and sections 25-7-102 (2)(g) and 25-7-140.          The commission shall provide forms of application and shall receive all such applications for review of the classification of any attainment, nonattainment, or unclassifiable area within the state made pursuant to section 25-7-106 (1) or 25-7-107 (2), all applications for designation or redesignation made pursuant to section 25-7-208, and all applications for any revision of general application of the state implementation plan and shall set such applications for hearing and determination by the commission in accordance with the provisions of section 25-7-119.    The commission shall employ a technical secretary and shall delegate to such secretary such duties and responsibilities as it may deem necessary; except that no authority shall be delegated to such secretary to adopt, promulgate, amend, or repeal standards or regulations, or to make determinations, or to issue or countermand orders of the commission. Such secretary shall have appropriate practical, educational, and administrative experience related to air pollution control and shall be employed pursuant to the state personnel system laws.      The commission and the state board of health shall hold a joint public hearing during the month of October of each year in order to hear public comment on air pollution problems within the state, alleged sources of air pollution within the state, and the availability of practical remedies therefor; and at such hearing the technical secretary shall answer reasonable questions from the public concerning administration and enforcement of the various provisions of this article, as well as rules and regulations promulgated under the authority of this article.    On or before September 30, 1993, the commission shall publish and revise from time to time thereafter, as is necessary, a regulatory agenda which includes its schedule for future rule-making and its schedule for implementing section 25-7-109.3 and other air quality programs.       Prior to the hearing required under subsection (4) of this section, the commission shall prepare and make available to the public a report, which shall contain the following specific information:   A description of the pollution problem in each of the polluted areas of the state, described separately for each such area;    To the extent possible, the identification of the sources of air pollution in each separate area of the state, such as motor vehicles, industrial sources, and power-generating facilities;    A list of all alleged violations of emission control regulations showing the status of control procedures in effect with respect to each such alleged violation; and    Stationary industrial sources permitting information as follows:   The total number of permits issued;    The total number of hours billed for permitting;    The average number of hours billed per permit; and    The number of general permits issued.             Repealed.    (Deleted by amendment,L. 92, p. 1170, § 7, effective July 1, 1992.)    The commission shall adopt exhaust emissions standards for motor vehicles purchased for state use and shall assist the executive director of the department of personnel in determining those vehicles which meet or exceed such standards.    The commission shall promulgate such rules and regulations as are necessary to implement the provisions of part 5 of this article concerning asbestos control.    The commission shall promulgate rules concerning CFC and ozone-depleting compounds as follows:   Regulations requiring the recycling or reuse of any refrigerant containing CFC which is removed from the refrigeration system of a retail store, cold storage warehouse, or commercial or industrial building by any person who installs, services, repairs, or disposes of such system as a result of service to or disposal of such system;    Regulations prohibiting the intentional venting or disposal of any refrigerant containing CFC by the owner or operator of a retail store, cold storage warehouse, or commercial or industrial building and requiring the recycling or reuse of such refrigerant;    Regulations requiring the use of approved motor vehicle refrigerant recycling equipment during the repair or servicing of a motor vehicle air conditioner, requiring that such repair or servicing be done by a person certified in accordance with federal regulations, and including requirements for reclamation of refrigerants during the disposal of a vehicle;    Repealed.    Regulations which establish requirements for recycling;    Regulations which conform with the requirements of section 608 of the federal “Clean Air Act Amendments of 1990” to establish standards and requirements regarding the use and disposal of class I and class II ozone depleting compounds during the service, repair, or disposal of appliances and industrial process refrigeration. If federal training and certification requirements are adopted under section 609 of the federal “Clean Air Act Amendments of 1990” as of January 1, 1993, no state training and certification requirements shall be adopted. If the federal regulations are not adopted, then such state regulations shall contain training and certification requirements substantially similar to those required under section 609 of the federal “Clean Air Act Amendments of 1990”. Such regulations shall also include provisions for the imposition and collection of a certification fee sufficient to implement the training, certification, and enforcement requirements of this paragraph (f).    Repealed.    Rules that are necessary for the imposition and collection of a fee for registering as stationary sources refrigeration systems and other appliances that contain a minimum of one hundred pounds or use a drive system of one hundred horsepower or more and use ozone-depleting compounds. The fee set by the commission shall reflect the direct and indirect costs of registering refrigeration systems and appliances; however, such fee shall not exceed seventy-five dollars per unit and shall not exceed a maximum of three hundred dollars per facility.       The commission shall promulgate such rules and regulations as are necessary to implement the provisions of the emission notice and construction permit programs and the minimum elements of a permit program provided in Title V of the federal act.      The commission shall promulgate rules and regulations requiring motor vehicles which have manufacturer-installed diagnostic systems for emission controls to have such diagnostic systems inspected and maintained consistent with section 202 of the federal act as part of the periodic inspection of vehicle emission control systems required pursuant to this article.    This subsection (13) shall take effect July 1, 1994.       The commission shall repeal the clean vehicle fleet program mandated by section 246 of the federal act and shall replace such program if required by federal law.    The commission shall promulgate rules and regulations as are necessary to provide an emission reduction incentive permit fee credit program which provides for a permit fee reduction in the year following the year in which a permittee achieves an early reduction in emissions of hazardous air pollutants, consistent with the provisions of section 112 of the federal act and section 25-7-114.3.    The commission shall give priority to and take expeditious action upon consideration of the following:   A request by a unit of local government to investigate and resolve air quality problems associated with a source;    A request by a unit of local government for inclusion of a locally developed air pollution control measure in a state implementation plan;    A request by a unit of local government that the commission consider local concerns respecting environmental and economic effects in the context of a proceeding where the state is targeting a source for imposition of additional air pollution controls.         Not later than December 31, 2002, and no less frequently than every five years thereafter, the commission shall conduct rule-making hearings to approve an update to the emission inventories from state and federal public land management agency activities on public lands resulting in emissions of any criteria pollutant, including surrogates or precursors for that pollutant, that affect any mandatory class I federal areas in Colorado by reducing visibility in such areas. At a minimum, such inventories shall report on emissions from the sources set forth in paragraph (d) of this subsection (17).    The commission shall ensure that the division prepares inventories for all state land management agencies with jurisdiction over state lands, including, without limitation, the state land board, the department of agriculture, and the department of natural resources, to provide an inventory of emissions from land management activities that are sources of pollutant emissions that may affect any mandatory class I federal area in Colorado by reducing visibility in such areas; except that the commission shall exempt from the inventory requirement any sources or categories of sources that it determines to be of minor significance.    The commission shall use the emission inventories provided under this subsection (17) to develop control strategies for reducing emissions within the state as a component of the visibility long-term strategies for inclusion in the state implementation plan and for inclusion in any environmental impact statement or environmental assessment required to be performed under the federal “National Environmental Policy Act of 1969”, 42 U.S.C. secs. 4321 to 4347.    The rule-making hearing held to approve the inventories provided under this subsection (17) shall require public participation and shall require the reporting of both current emissions and projected future emissions, over at least a five-year period, from the following sources on public land that affect any mandatory class I federal areas in Colorado:   Stationary source emissions, based on existing air pollution emission notices filed with the division;    Mobile sources utilizing state lands, excluding state and federal highways;    Paved and unpaved roads;    Fires on public lands from all sources;    Biogenic sources, including emissions from flora and fauna.       Each inventory provided under this subsection (17) shall state the basis and methodology used to accumulate the data and shall be based upon data that are:   Developed no later than three years prior to the submittal; and    No more than five years old.          Upon petition by any person or on its own motion, for good cause shown, the commission may determine that the emission inventory of any criteria pollutant, including a surrogate or precursor for that pollutant, for a region of the state is inadequate for purposes of commission rule-making or adjudications in connection with development of the state implementation plan, selection of pollution control strategies, attribution of emissions to sources or categories of sources, or findings of adverse impacts. If, after conducting a public hearing in accordance with the rule-making provisions of the “State Administrative Procedure Act”, article 4 of title 24, C.R.S., the commission finds that the emission inventory should be revised to take into consideration existing credible studies or scientific data in order to reasonably attribute emissions to source categories, it shall direct that such revision be performed prior to a final rule-making or adjudication.    The commission may coordinate with the United States secretary of the interior and the United States secretary of agriculture to develop air quality management plans consistent with this article for federal lands pursuant to 16 U.S.C. sec. 530, 16 U.S.C. sec. 1604, and 43 U.S.C. sec. 1712.    The commission may, within existing resources:   Analyze a range of residential, commercial, and industrial biomass equipment for air emissions standards;    Identify biomass equipment that meets the emissions standards; and    Publicly post a statement of the parameters for equipment fueled by biomass that is smaller than one million British thermal units, as defined in section 8-20-201 (1.3), C.R.S., per hour and include a list of biomass equipment that meets the emissions standards.        (J) An electric utility that is not a qualifying retail utility as defined in section 40-2-125.5 (2)(c)(I) that is required to submit a clean energy plan or a wholesale generation and transmission cooperative that is required to file an electric resource plan pursuant to this subsection (1)(e) shall provide written notice to the division of intent to file a clean energy plan by August 1, 2021. An investor-owned utility that has not already filed a clean energy plan and that indicates an intent to file a clean energy plan shall file a clean energy plan with the public utilities commission with its next resource plan filing. The division shall verify emission reductions as part of the public utilities commission proceeding that reviews the resource plan. A utility other than an investor-owned utility or a wholesale generation and transmission cooperative utility that provided written notice of intent to file a voluntary clean energy plan pursuant to this subsection (1)(e)(VIII)(J) shall provide all information the division deems necessary to evaluate and verify the emission reductions claimed as part of a clean energy plan no later than December 31, 2021. The division shall, in consultation with the public utilities commission, fully evaluate and verify the clean energy plan. The utility must submit the verified clean energy plan to the public utilities commission in accordance with section 40-2-125.5 (5)(g)(I) no later than July 1, 2022. The division may approve alternate data submission and filing deadlines, to be no later than December 31, 2023, upon reviewing information supplied by a utility in conjunction with the utility's written intention to file if the emission reduction calculations are dependent on decisions of another utility subject to resource planning requirements of the public utilities commission.    (B) If an electric utility does not provide written notice of intent to file a clean energy plan with the division or does not submit a clean energy plan after expressing written intent to file a plan, the commission shall, within fifteen months after the electric utility's failure to provide written notice or submit a plan, adopt a rule to reduce greenhouse gas emissions caused by the electric utility's Colorado retail electricity sales of at least forty-eight percent by 2025 and eighty percent by 2030, including emissions associated with imported electricity, as compared to a 2005 baseline. The commission shall design the rules to accelerate near-term reductions in greenhouse gas emissions in order to reduce total cumulative emissions between the date of adoption and 2030.   (C) Clean energy plan filings must include projected emissions for each calendar year through 2030 to inform the statewide greenhouse gas planning process. The division shall evaluate the reported emissions and supplemental information in an electric utility's annual greenhouse gas reporting data submission made pursuant to the commission's rules to determine whether an electric utility is progressing consistent with the annual emissions projected by the plan and remains on track to achieve the reductions of the clean energy plan by 2030. If the division determines that the electric utility is not progressing as planned, the electric utility's annual greenhouse gas emissions exceed annual emissions projected as part of an approved clean energy plan for two consecutive years, or the electric utility's annual greenhouse gas emission reductions are not on track to achieve at least an eighty percent reduction below 2005 levels in greenhouse gas emissions by 2030, the division shall include this information in the next greenhouse gas progress briefing to the commission and the commission shall, within nine months after receiving the briefing from the division, adopt rules that require an updated clean energy plan to be filed that demonstrates achievement of the 2030 targets and the cumulative emission reductions that were projected in the initial clean energy plan. The updated clean energy plan, once verified by the division, becomes the operative plan for purposes of subsection (1)(e)(VIII) of this section regarding the commission's regulatory requirements.   (D) Notwithstanding subsections (1)(e)(VIII.5)(A) to (1)(e)(VIII.5)(C) of this section, a qualifying retail utility with a clean energy plan that has been approved and verified in accordance with section 40-2-125.5 and subsection (1)(e)(VIII)(C) of this section and a wholesale generation and transmission cooperative with an electric resource plan that has been filed in accordance with subsection (1)(e)(VIII)(I) of this section and that has been approved are not subject to subsections (1)(e)(VIII.5)(A) to (1)(e)(VIII.5)(C) of this section. Progress of emission reductions for an electric utility that is an investor-owned retail utility with a clean energy plan that has been approved and verified in accordance with section 40-2-125.5 and subsection (1)(e)(VIII)(C) of this section or a wholesale generation and transmission cooperative with an electric resource plan that has been filed in accordance with subsection (1)(e)(VIII)(I) of this section and that has been approved shall be assessed through the recurring resource planning process at the public utilities commission.   (B) A municipal gas distribution utility shall implement a clean heat plan program. The purpose of a clean heat plan is to reduce carbon dioxide and methane emissions to meet the state's greenhouse gas pollution reduction goals in section 25-7-102 (2)(g) . The clean heat plan must include a projection of the utility's greenhouse gas emissions through 2050.    (A) “GHG credit” means a tradeable compliance instrument in a physical or electronic format, the use of which is authorized pursuant to a regulatory program adopted by the commission that represents the reduction of one metric ton of carbon dioxide equivalent of greenhouse gas by a regulated source.   (B) “Regulated source” means a source of greenhouse gas that is subject to a rule adopted by the commission under subsection (1)(e) of this section that imposes specific and quantifiable greenhouse gas reduction obligations upon that source or group of sources.
