SACRAMENTO – The state Department of Toxic Substances Control (DTSC) is taking the next step in its investigation of chemicals in motor vehicle tires that can harm aquatic life by holding a virtual Zoom public workshop July 28 and 29.  Media may find the agenda and workshop materials, along with a registration link on the DTSC website.

The goal of the workshop is for industry experts, researchers, advocacy groups, and others to weigh in on DTSC’s proposal to regulate zinc and 6PPD under its Safer Consumer Products program. DTSC is concerned about the impacts on coho salmon and other aquatic life. DTSC also welcomes comments on other chemicals in tires that could be of concern.

The workshop follows an earlier announcement that DTSC granted a petition by the California Stormwater Quality Association (CASQA) to work with tiremakers to reduce the amount of zinc that gets into waterways.

DTSC is considering regulating tires under its innovative Safer Consumer Products  (SCP) program. California would become one of the first states to work with manufacturers to look for alternatives to these chemicals that are safer for the environment while allowing tires to continue to meet safety and performance requirements.
