The State of Montana finalized a reclamation plan for a mine in western Montana on July 24.
The Montana Department of Environmental Quality issued a final decision that will include the permanent diversion of Clancy Creek away from the eroding edges of Montana Tunnel Mining’s inactive mine south of Helena.
Tunnels Mining installed a pipe to temporarily divert Clancy Creek roughly seven years ago. DEQ Mining Bureau Chief Dan Walsh says that’s when part of the pit wall collapsed.
“It put the Clancy Creek channel in danger of going directly into the pit," he said.
