 Iron Mask Hydro, LLC; Notice of Preliminary Permit Application 
Accepted for Filing and Soliciting Comments, Motions To Intervene, and 
Competing Applications

August 27, 2010.
    On May 6, 2010, Iron Mask 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 Iron Mask Pumped 
Storage Project to be located near the U.S. Bureau of Reclamation's 
Canyon Ferry Lake in the vicinity of Townsend, Montana, in Broadwater 
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 225-foot-
high, 1,795-foot-long upper dam made of either zoned earth and rockfill 
or concrete-face earth and rockfill; (2) a 50-foot-high, 950-foot-long 
earth-filled upper saddle dike A; (3) a 20-foot-high, 400-foot-long 
earth-filled upper saddle dike B; (4) a 40-foot-high, 6,559-foot-long 
lower embankment made of zoned earth or rockfill; (5) an upper 
reservoir with a storage capacity of 4,888 acre-feet; (6) a lower 
reservoir with a storage capacity of 4,888 acre-feet; (7) a 1,626-foot-
long, 12.9-foot-diameter unlined upper low-pressure tunnel; (8) a 
4,809-foot-long, 12.9-foot-diameter unlined, concrete-lined, and steel-
lined pressure shaft; (9) a 200-foot-long, 12.9-foot-diameter concrete-
lined and steel-lined high pressure tunnel; (10) four 6.5-foot-diameter 
steel-lined penstocks (length to be determined) ; (11) a 5,073-foot-
long, 15.5-foot-diameter concrete-lined or unlined tailrace; (12) a 
260-foot-long, 65-foot-wide, 120-foot-high underground powerhouse 
located at a depth of 1,000 feet; (13) one 150-megawatt (MW), one 100-
MW, and one 50-MW reversible pump-turbines totaling 300 MW of 
generating capacity, with up to 100 MW of additional pumping capacity, 
for a total of 400 MW pumping capacity; (14) an approximately 3,000-
foot-long, 24-foot-high main access tunnel leading from the ground 
level to the powerhouse; and (15) a new single-circuit 230-kilovolt, 
4.9-mile-long transmission line with a 150-foot right of way.
    Annual energy production is estimated to be 919,800 megawatt hours.
