The bill addresses the environmental and health concerns associated with the chemical 6PPD, commonly used in motor vehicle tires. It recognizes that 6PPD breaks down into 6PPD-quinone, which is toxic to aquatic life, particularly Coho salmon, and is linked to urban runoff mortality syndrome. The legislation aims to reduce the use of 6PPD in Washington by designating it as a priority chemical and identifying motorized vehicle tires containing 6PPD as priority consumer products under the "Safer Products for Washington" initiative. This is part of a broader effort to protect aquatic ecosystems and sensitive populations from hazardous substances.

To implement these changes, the bill amends existing definitions in RCW 70A.350.010, including the formal definition of 6PPD, and establishes a new section that classifies motorized vehicle tires containing 6PPD as priority consumer products. The Department of Ecology is tasked with determining regulatory actions and adopting rules for these products, ensuring that safety for drivers and passengers is considered in the regulatory process. The bill also outlines a timeline for the department to identify priority chemicals and consumer products, as well as to adopt necessary regulations.
