Abstract
This decision document presents the Selected Remedy for Oregon Gulch OU10 within the California Gulch Superfund Site in Leadville, Colorado. The Selected Remedy includes active management of the seep currently discharging at the toe of the Oregon Gulch Tailing Impoundment during the interim period from implementation until the seep does not negatively impact surface water quality. Active management of the seep discharge will be performed during non-freezing conditions and will include collection and either pumping or transport of the collected flow to the Yak Tunnel Treatment Plant or other suitable treatment options. Design of the Selected Remedy will include a drain system at the toe of the embankment to allow the seep discharge to flow unrestricted and to be collected in a controlled manner.
