HB 1226: Manage Emissions from Electric Generating Units

The act requires the division of administration in the department of public health and environment (division), no later than July 2029, to propose a final rule (rule) establishing certain limits on the emission of nitrogen oxides and sulfur dioxide (emission limits) from an electric generating unit (unit) that is owned or operated by an electric utility; is located in the state; and emitted 200 tons or more of nitrogen oxides, or sulfur dioxide, or both in calendar year 2024 (covered unit). The rule must require compliance with the emission limits as soon as practicable after December 31, 2034, and must not cover units that, before December 31, 2029, have ceased operations; burn natural gas, fuel oil, or both only; or have certain systems installed. A unit that operates after December 31, 2034, must install certain pollution controls and comply with the emission limits on or before December 31, 2034.     An owner or operator of a unit is required to provide quarterly emission reports showing compliance with the rule to the division. On August 1, 2029, the air quality control commission in the department of public health and environment (AQCC) must submit to the general assembly a list of any units that are subject to a federal order. If there are any units subject to a federal order, the AQCC must also submit to the general assembly recommendations on whether to amend the requirements for units subject to federal order.     An investor-owned utility or wholesale electric cooperative that is the owner or operator of a unit is required, beginning 150 days after the issuance of a federal order requiring the unit to remain operating after the unit was scheduled to retire (order) and continuing every 90 days until the order is no longer in effect, to file a report with the public utilities commission (commission) that contains certain information about the costs to operate the unit and the amount of electricity generated by the unit. The commission must make these reports publicly available. An investor-owned utility is also permitted to submit an application for a financing order to recover the costs of complying with an order.     Any decision by the commission approving or modifying a portfolio in an electric resource plan of an investor-owned utility serving more than 500,000 customers must approve an amount of accredited capacity that allows the investor-owned utility to reliably achieve certain retirement and carbon dioxide emission reduction requirements. This requirement applies to an investor-owned utility serving more than 500,000 customers until the division determines that the investor-owned utility has achieved certain carbon dioxide emission reductions or until the investor-owned utility has retired all covered units, whichever is later.(Note: This summary applies to this bill as enacted.)

SB 3: End-of-Life Management of Electric Vehicle Batteries

Senate Bill 25-163, concerning the establishment of battery stewardship programs for the disposal of certain batteries, created the 'Battery Stewardship Act', which requires the establishment of battery stewardship organizations and the submittal of battery stewardship plans to the executive director of the department of public health and environment (executive director) for the collection, transportation, processing, and recycling of certain batteries.     The act expands the scope of the 'Battery Stewardship Act' to cover the end-of-life management of propulsion batteries, which are batteries that are primarily used to supply power to an electric or hybrid vehicle, and establishes requirements concerning propulsion batteries that differ from the requirements for the batteries currently contemplated by the 'Battery Stewardship Act'.     On or before July 1, 2027, a person selling, offering for sale, or distributing propulsion batteries or vehicles containing a propulsion battery in or into the state (propulsion battery provider) is required to register with the department of public health and environment (department).     On or before January 2, 2029, a propulsion battery provider or group of propulsion battery providers must submit to the executive director an education and outreach plan that contains certain information about the management of propulsion batteries. On and after July 1, 2029, the act prohibits a propulsion battery provider from selling, making available for sale, or distributing a propulsion battery in or into the state unless the propulsion battery provider has submitted an education and outreach plan that meets the requirements of the act. The act also requires a propulsion battery provider to develop and maintain at least one website that, among other things, includes the information in the propulsion battery provider's education and outreach plan.     The act requires propulsion battery providers to collect certain unwanted propulsion batteries and ensure the responsible management of the unwanted propulsion batteries collected. In addition, the act requires a propulsion battery provider to, on and after July 1, 2029, label a propulsion battery and specifies the information that must be included on the label. On or before June 1, 2030, and on or before each June 1 thereafter, a propulsion battery provider is directed to submit an annual report to the executive director covering the preceding calendar year of the responsible management of the propulsion batteries collected by the propulsion battery provider.     A propulsion battery provider is required to pay a program initiation fee to the department. The amount of the program initiation fee for each propulsion battery provider is based on each propulsion battery provider's percentage of all propulsion battery vehicles registered in the state. On or before July 1, 2030, and on or before each July 1 thereafter, a propulsion battery provider is also required to pay an annual fee to cover the department's cost of implementing, administering, and enforcing the act. The solid and hazardous waste commission is directed to establish the annual fee amount by rule on or before July 1, 2029.     The act specifies how the department is required to implement, administer, and enforce the act. For example, the department is required to assess annual reports submitted by propulsion battery providers, compile a list of entities registered with the department, provide a digital registration form that an entity can use to register, and conduct an email survey with registered entities to request feedback on the functioning of the propulsion battery management program.     The act also sets forth requirements for persons that remanufacture a propulsion battery; persons that use a propulsion battery for a different use than the use for which the propulsion battery was originally designed; commercial entities that take possession of a propulsion battery for the purpose of selling, dispositioning, repairing, reusing, or recycling the propulsion battery; and entities that conduct propulsion battery recycling.     On and after July 1, 2029, the disposal of propulsion batteries at a solid waste disposal site and facility is prohibited.(Note: This summary applies to this bill as enacted.)

SB 171: Disposal of Preproduction Plastic Materials

Senate Bill 26-016, enacted in 2026, prohibits a person from disposing of preproduction plastic materials at a location that does not have federal interim status, a federal permit granted pursuant to the federal 'Solid Waste Disposal Act', or a state permit for the treatment, storage, or disposal of hazardous waste at a hazardous waste site.     The act removes this prohibition and instead prohibits the disposal of preproduction plastic materials at a location that is not a solid wastes disposal site and facility with a certificate of designation.(Note: This summary applies to this bill as enacted.)

SB 141: Wildlife Collision Prevention

Beginning on January 1, 2027, the act authorizes an optional collision prevention fee (fee), which is collected at the time of registration of a passenger motor vehicle, light-weight truck, motorcycle, or recreational vehicle (motor vehicle). An individual may decline to pay the fee when registering a motor vehicle, and nonpayment of the fee does not affect the individual's ability to register the motor vehicle. In connection with imposing the fee, the statewide bridge and tunnel enterprise (enterprise) within the department of transportation (department) is required to collaborate with:The department of revenue and county clerks to develop language to notify individuals about the fee, including explicit language regarding the ability to decline to pay the fee and the fact that nonpayment of the fee will not affect an individual's ability to register a motor vehicle; andThe department of revenue, the department, county clerks, the division of parks and wildlife, and other impacted stakeholders to conduct a public outreach campaign to educate the public about the fee and what benefits the fee will provide. The enterprise is required to initiate the public outreach campaign as soon as practicable and must develop and deliver customer-facing educational materials to county clerks on or before December 1, 2026.The fee amount is set at $5 and, beginning in state fiscal year 2028-29, the enterprise is allowed to adjust this fee amount upward for inflation.     75% of the revenue from the fee is credited to the newly created collision prevention fund (fund), which is continuously appropriated to the enterprise for use in the following ways:To fund wildlife safe passage projects, defined as one or more projects that reduce wildlife-vehicle collisions and improve habitat connectivity by providing wildlife road crossings;To provide matching money as required by federal grant programs relating to wildlife safe passage projects; To expend for administrative and personnel expenses related to those purposes; andTo promote the fee and fund to maximize participation in the optional fee, in collaboration with the department of revenue, impacted stakeholders, and interested organizations.In determining which wildlife safe passage projects the enterprise will undertake, the enterprise is required to:Consult with the division of parks and wildlife (division) and the Colorado wildlife and transportation alliance;Consult with the tribal government if the project is on or adjacent to tribal land;Consult with relevant local governments with jurisdiction over the area of the proposed project and any relevant local organizations engaging in work to reduce vehicle collisions;Consider studies concerning the prioritization of wildlife within the state;Consider whether the wildlife safe passage project is related to a bridge or tunnel project undertaken by the enterprise; andIn consultation with the division, consider opportunities for landowner agreements or additional conservation efforts that may be necessary to ensure the continued functionality of infrastructure associated with a proposed wildlife safe passage project.     25% of the revenue from the fee is credited to the wildlife cash fund and continuously appropriated to the division to provide services related to wildlife connectivity and wildlife crossing-related conservation efforts.     The act also modifies the process for the keep Colorado wild pass fee, which is an existing optional fee paid at the time an individual registers a motor vehicle, to align with the process for the collision prevention fee by removing the presumption that an individual who declines to pay the keep Colorado wild pass fee is presumed to decline to pay that fee in subsequent years with respect to registration of the same motor vehicle. With this change, an individual must affirmatively opt out of the payment of both the keep Colorado wild pass fee and the collision prevention fee each year that the individual registers the motor vehicle.     For the 2026-27 state fiscal year:$53,516 is appropriated from the DRIVES cash fund to the department of revenue for use by the division of motor vehicles; Of funds appropriated from the parks and outdoor recreation cash fund to the department of natural resources for use by the division, $778 is reappropriated to the department of revenue for use by the division of motor vehicles; and$19,940 is appropriated from the legal services cash fund, from revenue received from the department from the collision prevention fund, to the department of law to provide legal services for the department.(Note: This summary applies to this bill as enacted.)

SB 182: Updated Clean Energy Plan Municipally Owned Utility

Current law requires certain entities to file, or allows certain entities to voluntarily file, a clean energy plan to achieve an 80% reduction in greenhouse gas emissions caused by the entity's electricity sales in Colorado by 2030, relative to 2005 levels (2030 emission reductions).     The act repeals current law stating that clean energy plans submitted by a cooperative electric association or a municipally owned utility under certain circumstances are deemed approved by the public utilities commission (commission) and requiring the division of administration in the department of public health and environment (division) to consult with the commission in verifying a clean energy plan submitted by a cooperative electric association or a municipally owned utility. The act also repeals current law stating that voluntary submission of a clean energy plan by a cooperative electric association or a municipally owned utility does not alter the entity's regulatory status with respect to the commission.     A municipally owned utility that has encountered challenges in achieving the 2030 emission reductions may submit to the division, no later than December 31, 2026, an updated clean energy plan that demonstrates achievement of the 2030 emission reductions by the earliest date possible on or after December 31, 2029, but no later than December 31, 2032.     A municipally owned utility that submits an updated clean energy plan to the division must:Provide a detailed generation and transmission plan to the division with the updated clean energy plan;Provide an annual report to the division beginning January 1, 2028, and continuing each year until December 31, 2033, that contains certain information related to the updated clean energy plan;Cease burning coal by December 31, 2032; andSeek to achieve certain additional reductions in greenhouse gas emissions without impairing the municipally owned utility's ability to maintain certain electric reliability standards.     The updated clean energy plan must be verified by the division.(Note: This summary applies to this bill as enacted.)

SB 192: Producer Responsibility Dues Appeals Process

The producer responsibility program for statewide recycling (program) provides recycling services to covered entities in the state and is financed through annual dues assessed against producers of products that use packaging materials and paper products (producers).     The bill reaffirms the authority of the solid and hazardous waste commission in the department of public health and environment (department) to direct an appeals process whereby producers may contest the program dues assessed against them by requesting a hearing before the producer responsibility program for statewide recycling advisory board (advisory board). If a producer requests a hearing before the advisory board, the advisory board is required to hold the hearing and issue written recommendations to the department as to whether the dues assessed against the producer should be adjusted. The department is required to make a determination whether to approve or reject the advisory board's recommendations regarding the assessed dues within 45 days after receiving the advisory board's recommendations on the matter. The department's determination is a final agency action subject to judicial review.(Note: This summary applies to the reengrossed version of this bill as introduced in the second house.)

HB 1112: Regulation of Underground Injection Control Wells

The bill grants the energy and carbon management commission (commission) authority over class I, class IV, and class V injection wells and allows the commission to seek and adopt rules related to primacy from the United States environmental protection agency (EPA) for these classes of injection wells. The rules adopted by the commission may only be more stringent than corresponding federal requirements if certain findings are made at a public hearing. The commission may assess and collect fees related to the regulation of class I, class IV, and class V injection wells. A person that willfully violates a rule, permit, authorization, or order of the commission related to these classes of injection wells commits a misdemeanor and is subject to certain penalties. The executive director of the department of resources (executive director) is required to propose initial spending authority in the amount necessary to enforce rules for the permitting, authorization, and regulation of class I, class IV, and class V injection wells. The office of state planning and budgeting (OSPB) is also required to submit a proposal to eliminate or minimize the impact of associated fee revenue for the first state fiscal year that the fee revenue is assessed on the state fiscal year spending limitation in the state constitution.     The bill also grants the mined land reclamation board (board) authority over class III injection wells and allows the board to seek and adopt rules related to primacy from the EPA for class III injection wells. The board may assess and collect fees related to the regulation of class III injection wells. The rules adopted by the board may only be more stringent than corresponding federal requirements if certain findings are made at a public hearing. A person that violates a rule, permit, authorization, or order of the board related to class III injection wells or that operates a class III injection well without a permit from the board is subject to certain penalties. The bill also provides that a class III injection well is not eligible for an exemption from designated mining operation status, which status subjects the operator to certain rules adopted by the board. The executive director is required to propose initial spending authority in the amount necessary to enforce rules for the permitting, authorization, and regulation of class III injection wells. OSPB is also required to submit a proposal to eliminate or minimize the impact of associated fee revenue for the first state fiscal year that the fee revenue is assessed on the state fiscal year spending limitation in the state constitution.(Note: Italicized words indicate new material added to the original summary; dashes through words indicate deletions from the original summary.)(Note: This summary applies to the reengrossed version of this bill as introduced in the second house.)
