WA HB1550

Establishes producer responsibility requirements for electric vehicle propulsion batteries, making battery providers responsible for end-of-life management including collection, transport, and recycling at no cost to auto recyclers or vehicle wreckers

Prohibits disposal of propulsion batteries in landfills beginning June 1, 2029, and requires solid waste facilities to refuse such batteries

Sets minimum recycling efficiency rates for specialized battery recyclers: by December 31, 2029, recovery of at least 85% cobalt, 90% copper, 50% lithium, and 85% nickel; increasing to 90% cobalt, 95% copper, 80% lithium, and 90% nickel by December 31, 2031

Requires battery providers to register with the Department of Ecology by January 1, 2026, and submit annual reports beginning April 1, 2029, detailing battery volumes managed, recycled, reused, repurposed, and remanufactured

Authorizes civil penalties up to $1,000 per violation per day (or $10,000 for repeat violations) and creates the electric vehicle battery recycling account funded by annual registration fees from battery providers to cover department administration costs
