November 8, 2023 โ The U.S. Environmental Protection Agency (EPA) will investigate 6PPD-quinone, a chemical found in most tires that is toxic to salmon, under the Toxic Substances Control Act.
The action is in response to a petition brought by environmental group Earthjustice on behalf of the Yurok, Port Gamble SโKlallam, and Puyallup Tribes to ban the use of 6PPD in and for tires. While the EPA didnโt outright ban the chemicals, it has granted the tribesโ petition and will issue an advance notice of proposed rulemaking for 6PPD and โinitiate additional data gathering activities.โ
