The Center for Biological Diversity and Western Environmental Law Center sued numerous federal agencies, including the Environmental Protection Agency and U.S. Fish & Wildlife Service, over their alleged failure to protect Chinook and coho salmon, Southern Resident killer whales, steelhead trout, and bull trout from the effects of toxic cyanide dumping into Washington State waters by industrial facilities over the past three decades. The case is pending in the U.S. District Court for the District of Columbia.
