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.
