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.)

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.)
