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.)

For an offense of soliciting for commercial sexual activity with a child, if the court sentences the person to probation, the court shall order as a condition of probation that the person serve 364 days in the county jail.     In the crime of soliciting for commercial sexual activity with a child, the act adds knowingly soliciting a child for commercial sexual activity as a means of committing the offense and requires that when arranging or offering to arrange a meeting, the offender must know that meeting will facilitate commercial sexual activity with a child. The act removes the spousal exception from the crime of engaging in commercial sexual activity with a child.     The act makes the penalty for internet luring of a child a class 3 felony when the offense is committed with the intent to meet for the purpose of engaging in commercial sexual activity. In this circumstance, a court is required to sentence the offender to at least the minimum of the presumptive range for the class 3 felony.(Note: This summary applies to this bill as enacted.)

Colorado Mandatory Lethality Assessment Act

The act creates the 'Colorado Mandatory Lethality Assessment Act', which requires peace officers to conduct a lethality assessment when responding to a domestic violence incident and include the completed lethality assessment in the incident report. A peace officer is not required to administer a lethality assessment if a victim is unavailable, not at the scene, incapacitated, or if circumstances otherwise make the administration of the lethality assessment impossible or impracticable. If the lethality assessment indicates that an individual is a high-risk victim, or if the lethality assessment does not indicate a victim is high-risk but a peace officer determines an individual is a high-risk victim based on the totality of the circumstances, the peace officer is required to immediately contact a community-based victim's advocate either by phone or in person and provide the high-risk victim the opportunity to speak with the advocate.     The act requires the attorney general's office, in consultation with a Colorado-based coalition that advocates for survivors of domestic violence, to develop a mandatory training for peace officers to learn how to administer the lethality assessment and provide victim referrals. No later than June 1, 2027, the attorney general is required to make the training available and offer assistance to law enforcement agencies in providing the training. Beginning July 1, 2027, the act requires each law enforcement agency to ensure that each peace officer employed by the agency has completed the mandatory training; except that a law enforcement agency that has provided training on the administration of lethality assessments prior to July 1, 2027, is not required to provide additional training.     Beginning January 2028, and each January thereafter, the act requires the attorney general's office to report to the general assembly certain information related to lethality assessments conducted in the previous calendar year. No later than January 31, 2030, the domestic violence fatality review board shall evaluate the effectiveness of mandatory lethality assessments and referrals to resources and submit the evaluation to the general assembly.     The act does not impose criminal, administrative, or civil liability on any person for an act or omission made in good faith related to administering a lethality assessment.(Note: This summary applies to this bill as enacted.)
