The Washington State Department of Ecology has issued a proposed standard limiting the amounts of copper and other heavy metals that can be contained in brake pads.
The rule, called the “Better Brakes Law,” came down from the agency June 20. It implements a state law that mandates the phaseout of copper, asbestos and other substances in brake pads.
“Copper is highly toxic to fish and other aquatic species,” said the preamble to the new rule. “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.”
