“If EPA truly cares about protecting the environment and the Tribe’s Treaty Rights, not just industry’s pocketbooks, it will act now.” “To see 6PPD-q kill the salmon that are reared in the Port Gamble S’Klallam Tribe’s own streams and from its own hatchery is an unconscionable slap in the face to a people who rely on salmon for their wellbeing, in addition to being a gross violation of the Tribe’s rights as enshrined in the 1855 Treaty of Point No Point,” said Josh Carter, the Port Gamble S’Klallam Tribe’s environmental scientist. The Tribes contend that 6PPD in tires poses unreasonable risks to the environment, requiring the EPA to regulate the chemical under the Toxic Substances Control Act. Exposure to 6PPD-q can kill coho salmon within hours, and the chemical is responsible for “urban runoff mortality syndrome,” which kills up to 100% of coho returning to spawn in urban streams. When 6PPD reacts with ground-level ozone, it breaks down into 6PPD-q – the second most toxic chemical to aquatic species ever evaluated by the EPA. The Yurok, Port Gamble S’Klallam, and Puyallup Tribes today petitioned the Environmental Protection Agency (EPA) to establish regulations prohibiting the manufacturing, processing, use, and distribution of 6PPD in and for tires – a chemical used by companies worldwide.
