Concerning 6PPD and regrettable 6PPD substitutes in tires.

Washington's SB 6119 bans the use of 6PPD (a chemical in tires that breaks down into toxic 6PPD-quinone) and "regrettable substitutes" in tires sold or distributed in the state by January 1, 2035. It requires tire distributors to pay a temporary fee for tires containing 6PPD while the industry develops safer alternatives, and prohibits any "regrettable substitute" not verified as safer by the Department of Ecology. The bill directly affects tire manufacturers, distributors, and retailers, aiming to protect salmon and other aquatic species by reducing toxic tire wear particles in waterways. This policy change aligns with Washington's goals for salmon recovery and reducing stormwater pollution from tire chemicals.
