The "Promoting Responsible End-of-Life Management of Electric Vehicle Batteries Act" establishes a comprehensive framework for the management of electric vehicle batteries at the end of their life cycle in New Mexico. The bill defines key terms such as "battery provider," "secondary handler," and "specialized battery recycler," and outlines the responsibilities of these entities in managing propulsion batteries. Notably, the act prohibits the disposal of propulsion batteries in landfills and mandates that all batteries be managed according to a specified battery management hierarchy, prioritizing reuse, repair, and recycling.

Additionally, the bill assigns responsibility for spent batteries to the battery provider, unless modified by a secondary handler or user, in which case the last party to modify the battery becomes responsible. It requires annual reporting from battery providers, secondary handlers, secondary users, and specialized battery recyclers to ensure compliance and track the management of batteries. The Department of Environment is tasked with notifying relevant parties about the landfill prohibition and ensuring adherence to the act's provisions. The act is set to take effect on January 1, 2026.
