We take protecting all water resources seriously. Professionals chose the tunnel entry location specifically because it is almost 200 feet above the water level. In order to keep water from leaving the mine and mixing with creek water, all planned openings or entry points to the mine (including air ventilation and escape routes) are located far above the water table. In addition, the tunnel route was chosen because it encounters the least amount of PAG (Potentially Acid Generating) rock of all alternatives available.
