Coffin Butte Energy Park, LLC; Notice of Preliminary Permit 
Application Accepted for Filing and Soliciting Comments, Motions To 
Intervene, and Competing Applications

September 21, 2010.
    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.

    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.
