The Environmental Protection Agency estimates it will cost more than $5 million for a partial cleanup of an abandoned copper mine in Douglas County that is leaching toxic metals into a creek that feeds the Umpqua River.
The money would pay to remove mining waste, a job that could cost $13 million, depending on the level of cleanup. Even more money would be required to deal with acidic water draining out of a tunnel.
The Register-Guard reports there's no money available for the work at the Formosa Mine, about 10 miles south of Riddle. It was closed by the state in 1993 for violating mining laws. The company that operated the mine is out of business and the EPA cannot identify a responsible party to foot the cleanup bill.
