SAN FRANCISCO — Two West Coast fishing associations — The Institute for Fisheries Resources and the Pacific Coast Federation of Fisherman's Associations — are suing 13 of the world's largest tire manufacturers, seeking "immediate injunctive relief" against the use of the antiozanant 6ppd in tire production.
The suit was filed Nov. 8 by the non-profit Earthjustice under Section 9 of the Endangered Species Act, in the U.S. District Court for Northern District of California in San Francisco.
"Defendants' inclusion of 6ppd in their tires directly harms plaintiffs, because the proliferation of 6ppd-quinone — and resulting die-offs of coho salmon, Chinook salmon and other salmonids — has decimated the commercial salmon fishing industry in which many of their fishing family members make their livelihoods," the lawsuit alleges
"In recent years, so few juvenile salmon have survived in California's rivers that the state has been forced to restrict access even to the most abundant fisheries and entirely suspend commercial salmon fishing for 2023."
6ppd is crucial to consumer safety in preventing cracking and splitting of tires during tire wear. However, 6ppd can morph into 6ppd-quinone during tire abrasion (reacting with ground-level ozone), an offshoot chemical that is toxic to fish.
The tire makers named in the suit are: Bridgestone Americas Inc.; Continental Tire the Americas L.L.C.; Giti Tire U.S.A. Ltd.; Goodyear; Cooper Tire & Rubber Co.; Hankook Tire America Corp.; Kumho Tire U.S.A. Inc.; Michelin North America Inc.; Nokian Tyres; Pirelli Tire North America; Sumitomo Rubber North America; Toyo Tire Holdings of Americas Inc.; and Yokohama Tire Corp.
