(1) This chapter implements chapter 70.285 RCW, which mandates a phase out of the use of copper, asbestos, and several heavy metals in brake friction material that is sold or offered for sale in Washington state.
(2) As brake friction material wears down, copper and other metals are deposited on roadways, where they are washed into our streams and rivers. Copper is highly toxic to fish and other aquatic species. Young salmon are especially susceptible to the effects of copper. Removing copper and other toxic metals from brake materials will help to clean up water bodies around the state.
