Bill > HB2421

This bill aims to protect aquatic species, particularly salmon, by restricting the use of a chemical called 6PPD (N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine), commonly found in tires to prevent cracking and degradation. When 6PPD reacts with oxygen and ozone on tire surfaces, it forms 6PPD-quinone, which is released as tire wear particles and pollutes waterways, causing a condition known as urban runoff mortality syndrome that kills coho salmon. The bill establishes a new chapter in state law that defines "6PPD," "regrettable 6PPD substitute" (a chemical that is not a safer alternative), and "safer alternative." Beginning January 1, 2035, it will be illegal to manufacture, sell, or distribute new vehicle tires containing intentionally added 6PPD or any "regrettable 6PPD substitute" identified by the Department of Ecology, unless the tires are for specific uses like aviation or military vehicles. The Department of Ecology is authorized to create rules to identify these harmful substitutes, and violations can result in civil penalties of up to $5,000 for a first offense and $10,000 for repeat offenses, with appeals possible to the pollution control hearings board. The bill also amends existing laws to include appeals related to penalties and orders issued under this new chapter.
