California legislates SB 615 for electric vehicle battery recycling program

The Assembly Environmental Safety and Toxic Materials Committee convened on June 17, 2025, to discuss critical legislation aimed at managing end-of-life electric vehicle (EV) batteries. The primary focus was on Senate Bill 615, which proposes the establishment of a program under the Department of Toxic Substance Control to ensure the proper handling and recycling of these batteries.

The bill aims to promote a sustainable circular economy by addressing the challenges posed by mismanaged hazardous waste. It emphasizes the importance of recycling EV batteries, which not only reduces the demand for raw materials but also mitigates the negative social, economic, and environmental impacts associated with mining. Additionally, the legislation highlights the potential for repurposing batteries for energy storage, thereby extending their useful life.

Committee members expressed concerns about the current lack of a robust policy framework to manage the growing number of EV batteries reaching the end of their life. Without clear management pathways, there is a risk of a hazardous waste crisis as the EV market expands. Evidence of this issue has already emerged, particularly in the aftermath of incidents like the LA fires, where burned EV batteries complicated cleanup efforts.

The discussion referenced previous legislation, specifically AB 2832, which established an advisory group to develop recommendations for maximizing the reuse and recycling of lithium-ion batteries in California. SB 615 builds on these recommendations and incorporates extensive stakeholder feedback to ensure effective management of EV batteries.

Key provisions of the bill include holding battery suppliers accountable for the proper management and recycling of batteries under warranty, as well as requiring auto shops and dismantlers to manage removed batteries responsibly. This could involve returning batteries to manufacturers, selling them for energy storage, or directing them to recyclers.

The bill also introduces a flexible structure to adapt to the evolving recycling market, ensuring that critical materials within EV batteries are effectively managed regardless of market fluctuations. This producer responsibility framework serves as a safeguard to maintain proper end-of-life management for these valuable resources.

In conclusion, the committee's discussions underscored the urgency of implementing a comprehensive strategy for EV battery management as the state continues to expand its electric vehicle infrastructure. The next steps will involve further deliberation on the bill and its potential impact on California's environmental safety and sustainability efforts.
