WASHINGTON—The U.S. Tire Manufacturing Association has offered formal comments on a California agency's assessment of alternatives for the tire manufacturing additive 6ppd.
6ppd, an antioxidant and antiozonant essential to passenger safety and harmful to coho salmon when transformed into 6ppd-quinone, was elevated in May as a priority substance to be studied by the California Department of Toxic Substances Control under the Safer Consumer Products Regulations (SCPR).
The formal comments were filed July 20 by the USTMA's Sarah Amick, vice president of environmental health safety and sustainability and senior counsel for the USTMA, on behalf of the 12 member organizations.
They essentially offer support for the DTSC's analysis and recommend several priorities for the agency as it moves forward, "for the protection of the environment as well as the driving public," according to the USTMA.
