Environmental Assessment for a Modification to Keystone Mine Plan of Operations CACA-33965
Sourdough Spring is located in Goler Wash in the Panamint Mountains. Bush Management Company (BMC) has a California State water license to divert and use up to 470 gallons per day from Sourdough Spring. This water right was established in 1941, before the area was added to Death Valley National Park. The NPS approved BMC's plan of operations, including the use and diversion of up to 470 gallons of water per day from Sourdough Spring.
BMC plans to use the water at Keystone Mine, located about one mile west of Sourdough Spring on lands administered by the Bureau of Land Management (BLM). In a related decision, the BLM approved BMC's plan for exploratory drilling at Keystone Mine. That project includes drilling on existing unpatented lode mining claims with less than one acre of disturbance.
The BLM prepared the Environmental Assessment analyzing the proposed modification to the Keystone Mine plan of operations. The National Park Service was a cooperating agency on the Environmental Assessment. However, each agency signed a separate decision document that applied only to lands under its jurisdiction.
A 30-day public comment period ended on October 12, 2018. The Environmental Assessment and each agencies' Finding of No Significant Impact decision document can be viewed at this website.
The National Park Service (NPS) has approved a plan of operations that includes diversion and use of up to 470 gallons of water per day from Sourdough Spring, within Death Valley National Park, for use at a mine outside the park.
