On August 25, 2010, Coffin Butte Energy Park, 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 Coffin Butte Pumped Storage Water Power Project (Coffin Butte Project) to be located in Wheatland County, Montana. 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.Start Printed Page 61748
The proposed project will consist of the following: (1) A 5,700-foot-long, 60-foot-high triangular earth and roller compacted concrete embankment; creating a 50-acre upper reservoir with a storage capacity of 2,500-acre-foot at an elevation of 6,420 feet National Geodetic Vertical Datum 1929 (NGVD 29); (2) a 6,300-foot-long, 60-foot-high oval earth and roller compacted concrete embankment; creating a 50-acre lower reservoir with a storage capacity of 2,500-acre-foot at an elevation of 5,200 feet NGVD 29; (3) an 18-foot-diameter, 5,000-foot-long steel-lined tunnel connecting the two reservoirs; (4) a powerhouse located on the steel-lined tunnel containing two reversible 125-megawatt (MW) turbine/generator units, for a total installed capacity of 250 MW; (5) a temporary earthen/rock diversion with a pump and 2-foot-diameter pipeline to bring initial fill water to the lower reservoir from Miller Creek; (6) a 2-foot-diameter well to bring groundwater to the project to make up evaporation and seepage losses; (7) an approximately 2-mile-long, 500-kilovolt (kV) transmission line connecting the powerhouse to an existing 500-kV transmission line in the area or a 7-mile-long, 230-kV transmission line connecting the powerhouse to the Two Dot substation; and (8) appurtenant facilities. The estimated annual generation of the Coffin Butte Project would be 880,000 megawatt-hours.
