British Columbia mining regulators have taken the first step toward paying to clean up an abandoned mine that has been leaking acid runoff into Alaska waters for decades.
The British Columbia Ministry of Energy, Mines and Petroleum Resources issued a request for proposals Nov. 6 soliciting bids to remediate the Tulsequah Chief mine located in the Taku River drainage about 10 miles upstream from the Alaska-British Columbia border.
State officials contend the multi-metal mine that operated for just six years has been leaking acid wastewater into the Tulsequah River, which feeds the Taku, since it was closed in 1957. The Taku River empties into the Pacific near Juneau and is one of the largest salmon-bearing rivers in Southeast Alaska.
The Alaska congressional delegation and Gov. Bill Walker’s administration have stepped up their demands for provincial officials to address the situation in recent years — largely at the behest of Southeast commercial fishing and Native groups — after the mine’s latest owners, Toronto-based Chieftain Metals Ltd., began bankruptcy proceedings in 2016.
Sen. Dan Sullivan and former Lt. Gov. Byron Mallott traveled to Ottawa to meet with Canadian officials in February to discuss their environmental and fishery concerns about government oversight of mining activity within transboundary watersheds in the province that flow into Alaska.
