Amid research linking a highly toxic tire chemical to salmon deaths in the Pacific Northwest, California officials are proposing a rule to require tire manufacturers to consider safer alternatives.
The proposed rule by the California Department of Toxic Substances Control comes after a 2020 study that identified the chemical 6PPD, which is used to give tires longer life, as the culprit behind decades of coho salmon deaths in Washington state.
