Feds, tribe sue Homestake for polluting South Dakota waterways Story-Date: 09:52 p.m. PST Tuesday , November 25, 1997 ------------------------------------------------------------ Feds, tribe sue Homestake for polluting South Dakota waterways SIOUX FALLS, S.D. (AP) -- Homestake Mining Co., already facing a lawsuit from the state of South Dakota for pollution, is now being sued by the federal government and the Cheyenne River Sioux Tribe. The tribe and the U.S. Justice Department said the San Francisco-based company polluted a watershed with more than 100 million tons of toxic mine tailings. The lawsuit is similar to one the state filed in September, also in U.S. District Court in Rapid City, S.D. The state's suit accused Homestake of polluting Whitewood Creek in the Black Hills with cyanide, arsenic and a variety of other mining waste for a century, stopping in 1977. The creek flows through Lead, where Homestake operates a gold mine. The latest suit said Homestake discharged mining wastes into the creek, the Belle Fourche River, the Cheyenne River and the Missouri River. The Cheyenne River Sioux Tribe's reservation borders the Cheyenne River and Lake Oahe, a huge Missouri River reservoir. "This case is critical to protect the health and safety of reservation residents as well as our treaty rights, waters and natural resources for the coming generations," Gregg Bourland, tribal chairman, said in a release. Homestake officials in Lead were unavailable for comment late Tuesday afternoon. The lawsuit was filed under the federal Superfund law and the Clean Water Act, the Justice Department said. The lawsuit says the wastes continue to seep into the soil and water, harming vegetation and wildlife. A Justice Department release said the federal government, the state and the tribe will tally up the damage to figure out what has to be done to restore the natural resources. Homestake spent over $100 million several years ago to clean up Whitewood Creek and prevent additional pollution. But state officials have argued that the job isn't finished. Neither the state's lawsuit nor the new one ask for any specific dollar damage amount. An 18-mile stretch of Whitewood Creek was on the U.S. Environmental Protection Agency's Superfund cleanup list for 10 years until being removed last year. Larry Mann, Homestake director of government and public affairs, said in September that EPA has told Homestake to make another assessment of the cleanup effort. He said Homestake violated no pollution law in dumping mine wastes into Whitewood Creek prior to 1977, when the practice was outlawed. ------------------------------------------------------------
