The Yakama Nation has given 60 days notice to federal officials of its intent to sue in U.S. District Court over a lack of progress and cooperation in regard to cleanup at the Bradford Island Superfund site. Under the notice, the tribe alleges standards and regulations have not been adhered to for Bradford Island, and the Army Corps of Engineers has failed to perform its duties. Representatives of the Yakama Nation, Environmental Protection Agency Region 10, the Corps, and the states of Oregon and Washington met on Tuesday to discuss Bradford Island, where toxic waste from the construction and operation of Bonneville Dam was disposed of for many years. Bradford Island was added to the BPA’s national priorities list in 2022.
