Document Description
The project consists of improving two existing mine drainage treatment systems (headwalls, piping, and infiltration trenches) at Corona Mine and Twin Peaks Mine, installing a third drainage treatment system for Corona Drain Tunnel Portal discharges, and mitigating physical and chemical hazards at both mines. Minor grading will be conducted on Oat Hill Mine Road (dirt road) and spurs to improve site access, and for the new supply trails constructed to access the Corona Drain Tunnel Portal and drainage treatment system.
