          - [Project No. 13836-000]

On August 30, 2010, Medicine Bow Hydro, LLC filed an application for a preliminary permit, pursuant to section 4(f) of the Federal Power Act (FPA), proposing to study the feasibility of the Medicine Bow Pumped Storage Project (Medicine Bow Project) to be located in Carbon County, Idaho. The sole purpose of a preliminary permit, if issued, is to grant the permit holder priority to file a license application during the permit term. A preliminary permit does not authorize the permit holder to perform any land-disturbing activities or otherwise enter upon lands or waters owned by others without the owners' express permission.

The proposed project will consist of the following: (1) A 9,200-foot-circumference, 60-foot-high earth or rockfilled embankment; creating an 88-acre upper reservoir with a storage capacity of 8,750-acre-foot at an elevation of 8,375 feet mean sea level (msl); (2) a 1,480-foot-long, 210-foot-high earth and rockfill or concrete-face rockfill dam; creating an 121-acre lower reservoir with a storage capacity of 8,900-acre-foot at an elevation of 7,325 feet msl; (3) a 19-foot-diameter, 600-foot-long concrete-lined low pressure tunnel; (4) a 19-foot-diameter, 5,060-foot-long high pressure concrete-lined tunnel; (5) a 280-foot-long, 70-foot-wide, 120-foot-high powerhouse containing one reversible 200-megawatt (MW) turbine/generator unit, and two 100-MW turbine/generator units, for a total installed capacity of 400 MW; (6) a 2,600-foot-long, 22.5-foot-diameter tailrace between the powerhouse and the lower reservoir; (7) an approximately 6.8-mile-long, 230-kilovolt transmission line connecting the powerhouse to the existing Miracle Mile-Cheyenne transmission line; and (8) appurtenant facilities. The estimated annual generation of the Medicine Bow Project would be 1,226,400 megawatt-hours.
