WA - Commercial fishing groups sue 13 US tire makers over rubber preservative that’s deadly to salmon
TACOMA, Wash. (AP) — The 13 largest U.S. tire manufacturers are facing a lawsuit from a pair of California commercial fishing organizations that could force the companies to stop using a chemical added to almost every tire because it kills migrating salmon.
Also found in footwear, synthetic turf and playground equipment, the rubber preservative 6PPD has been used in tires for 60 years. As tires wear, tiny particles of rubber are left behind on roads and parking lots, breaking down into a byproduct, 6PPD-quinone, that is deadly to salmon, steelhead trout and other aquatic wildlife when rains wash it into rivers.
“This is the biggest environmental disaster that the world doesn’t quite know about yet,” said Elizabeth Forsyth, an attorney with the environmental law firm Earthjustice, which is representing the fishing groups. “It’s causing devastating impacts to threatened and endangered species.”
The Institute for Fisheries Resources and the Pacific Coast Federation of Fishermen’s Associations filed the lawsuit in U.S. District Court in San Francisco on Wednesday against Goodyear, Bridgestone, Continental and others.
In an emailed statement, Bridgestone spokesman Steve Kinkade said the company would not comment on the lawsuit, but that it “remains committed to safety, quality and the environment and continues to invest in researching alternative and sustainably sourced materials in our products.”
The Environmental Protection Agency on Nov. 2, 2023, granted a petition submitted by Native American tribes in California and Washington state asking federal regulators to prohibit the use of the chemical 6PPD in tires due to its lethal effect on salmon, steelhead trout, and other wildlife.
Several of the other tire makers did not immediately return emails seeking comment. The U.S. Tire Manufacturers Association, which is not named as a defendant, said in a statement last week that work is already underway to identify a chemical to replace 6PPD while still meeting federal safety standards. Forcing the companies to change too quickly would be bad for public safety and the economy, it said.
“Our members continue to research and develop alternative tire materials that ensure tire performance and do not compromise safety, consistent with our industry’s commitment to sustainability and respect for the environment,” the association said in another statement Wednesday.
The fishing organizations filed the lawsuit a week after U.S. regulators said they would review the use of 6PPD in tires in response to a petition from three West Coast Native American tribes. Coho salmon appear to be especially sensitive to the preservative; it can kill them within hours, the tribes argued.
The tribes — the Yurok in California and the Port Gamble S’Klallam and Puyallup tribes in Washington — asked the Environmental Protection Agency to prohibit 6PPD earlier this year.
The agency’s decision to grant the petition is the start of a long regulatory process that could see it banned — one of several effort on different fronts to recover salmon populations as well as the endangered killer whales in the Pacific Northwest that depend on them.
The chemical’s effect on human health is unknown, the EPA noted.
Forsyth said that as long as 6PPD remains in tires, the companies need a federal permit allowing them to harm species that are protected under the Endangered Species Act. To do so, they would have to show that they’ve mitigated the harm to salmon to the fullest extent possible, which could mean funding stormwater improvements to keep the chemical from entering aquatic habitats.
No tire company has such a permit, the lawsuit said.
