The proposed project includes pumping of water from Coso Hay Ranch in Rose Valley to provide fluid to the geothermal field in the China Lake Naval Air Weapons Center. Water will be withdrawn from two existing wells at the Coso Hay Ranch property at an average rate of 3,000 gallons per minute (gpm), or approximately 4,800 acre-feet per year (each well will have a down-hole shaft-driven pump with a capacity of 2,000 gpm, and will be pumped for 18 hours per day). Power for the proposed project is proposed to be supplied by a new 3 mega watt (MW) substation to be constructed by Southern California Edison (SCE) adjacent to the pumping equipment on the Hay Ranch property (the existing dilapidated mobile home and equipment shed will be removed). There will also be prefabricated 16' x 10' mechanical-electrical equipment building constructed near the pumping equipment. The substation will have security lighting of a low intensity and low sodium type, which will be photo sensor controlled. Maintenance lighting will have high pressure sodium lights controlled by a manual switch which is left in the "off" position except for emergency night maintenance or operations. Landscaping and an automatic irrigation system around the substation will be installed by a certified licensed landscape architect and will be designed to filter views from nearby residences and commercial areas. An 8-foot high chain link/barbed wire fence will enclose the facility.
