U.S. regulators say they will review the use of a chemical found in almost every tire after a petition from West Coast Native American tribes that want it banned because it kills salmon as they return from the ocean to their natal streams to spawn. The tribes asked the Environmental Protection Agency to prohibit the rubber preservative 6PPD earlier this year, saying it kills fish when rains wash it from roadways into rivers. Other states, including Vermont, Rhode Island, and Connecticut, also wrote the EPA, citing the chemical’s “unreasonable threat” to their waters and fisheries.
