SB 3 Colorado Senate · 2026 Regular Session

End-of-Life Management of Electric Vehicle Batteries

Summary
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.)

What changed between versions

Rerevised Final Act · 5 edits · May 21, 2026
MODERATE
This bill expands the existing Battery Stewardship Act to specifically include electric vehicle propulsion batteries, which were previously excluded. The changes establish a new legal framework requiring manufacturers and distributors to finance a state-approved system for the safe collection, reuse, and recycling of these batteries. This shift is critical for managing the growing volume of retired EV batteries, reducing fire risks from improper disposal, and recovering valuable materials like critical minerals.
Scope change
The bill's scope expanded from covering only general batteries (like those in power tools) to explicitly including propulsion batteries used in electric and hybrid vehicles.
DEFINITION

Added specific definitions for 'propulsion battery,' 'battery management hierarchy,' 'dispositioning,' and 'orphaned battery' to clarify how these batteries should be managed.

REQUIREMENT

Mandated that producers and providers of propulsion batteries must finance and implement a coordinated system for their end-of-life management, including reuse, remanufacturing, and recycling.

Required organizations managing these batteries to create educational materials and safety information for the public regarding battery storage and collection.

TIMELINE

Set a deadline of April 1, 2028, for organizations to submit approved management plans, with participation requirements for providers beginning on August 1, 2028.

ELIGIBILITY

Modified the definition of 'covered battery' to explicitly exclude batteries assembled by vehicle manufacturers for use in vehicles, thereby carving out propulsion batteries for this new, separate regulatory scheme.
