The Environmental Protection Agency will review the use of a chemical found in tires that has been linked with the deaths of salmon on the U.S. West Coast.
Spurred by a petition from West Coast tribes, the EPA will study the impact of the rubber preservative 6PPD with an eye to potentially banning its use. Through normal wear and tear, tires shed tiny bits of rubber rich in 6PPD. The preservative reacts with ozone pollution to form 6PPD-q, which is toxic to fish. Rainfall washes the chemical from streets and parking lots into streams and rivers. In the Pacific Northwest, 6PPD-q has proved deadly to coho salmon.
“These salmon and other fish have suffered dramatic decreases in population over the years,” EPA assistant administrator Michal Freedhoff, said in a statement. Addressing the use of 6PPD, he said, “is one way we can work to reverse this trend.”
