Senate panel adopts negotiated EV battery bill, shifting responsibility toward manufacturers

Senate Bill 3, the sponsors said, establishes a market‑oriented framework to ensure electric vehicle propulsion batteries are collected, reused where practical, repurposed and ultimately recycled according to environmental standards that recover critical minerals.

Senator Wallace, joined by Senator Cutter, described the strike‑below amendment (L001) as the product of months of stakeholder negotiations intended to strike a balance among manufacturers, recyclers, environmental groups and secondary handlers. "This approach recognizes that manufacturers are well positioned to handle the products they design and place into the marketplace," Wallace said, explaining the amendment shifts many responsibilities to automotive manufacturers while preserving a regulatory backstop to prevent unsafe storage or disposal.

Witnesses and technical experts filled the hearing: scientists from the Union of Concerned Scientists and Conservation Colorado pushed for strong recycling standards and prohibitions on smelting whole batteries; representatives from the Automotive Recyclers Association and independent dismantlers pressed for clear rules for secondary handlers, testing protocols for state of health and state of charge, and a producer backstop to avoid 'negative value' batteries stranding recyclers. Manufacturers and industry groups (including the Alliance for Automotive Innovation, Rivian and Redwood Materials) generally supported the negotiated strike‑below but remained in an "amend" position on specific items such as mineral recovery metrics, enforcement constructs and fee design.

Key technical questions on safety and logistics arose: current testimony confirmed that there are no large‑scale lithium‑ion battery recyclers in Colorado yet and that transportation and hazardous‑material rules depend on battery condition and damage. Stakeholders warned of the risk of abandoned or improperly stored batteries and urged clarity on who pays for processing batteries with little to no commodity value.

Committee discussion included fiscal and implementation concerns. Sponsors said the strike‑below significantly reduces the bill's fiscal note by eliminating a proposed recycler certification program and transferring more operational responsibility to producers. With no objection the committee adopted L001. Senator Exum then moved the bill, as amended, to the Committee on Appropriations with a favorable recommendation; the referral passed on a roll call vote of 8–1.

The sponsors and stakeholders committed to continue negotiations on technical details—mineral recovery measurement, accountability for secondary handlers, and orphan battery studies—before the bill reaches later stages of debate.
