    l. Project Description: The Seminoe Project would utilize 
Reclamation's existing 1,017,280 acre-feet Seminoe reservoir on the 
North Platte River as the lower reservoir and would include the 
following new facilities: (1) a 8,498-foot-long circumference, 20-foot 
wide, 65 to 185-foot-high, roller-compacted concrete (RCC) dam 
impounding a 10,800-acre-foot upper reservoir at a crest elevation of 
7,455 feet and a maximum operating pool elevation of 7,445 feet 
(allowing for a 10-foot freeboard between the maximum operating level 
and the dam crest); (2) a 200-foot-long concrete, ungated, ogee crest 
emergency spillway; (3) a 75-foot-diameter, covered bell-mouth intake 
set near the southwestern edge of the upper reservoir at an elevation 
of 7,295 feet; (4) an approximately 680-foot-long, 32-foot-diameter 
concrete lined-headrace tunnel connecting to a 615-foot-long, 24-foot-
diameter aboveground steel conduit which would extend underground for 
an additional 2,470 feet before discharging to a 30-foot-diameter 
vertical, concrete-lined shaft; (5) a 165-foot-long, 17-foot-diameter 
concrete, steel-lined penstock connecting from the vertical shaft to 
the pump-turbines; (6) three pump-turbines each rated at 324 megawatts 
(MW) (for a combined total generating capacity of 972 MW) located in 
the underground powerhouse (machine hall); (7) an approximately 4,070-
foot-long, 31-foot-diameter concrete-lined tailrace tunnel discharging 
water to a lower intake structure within the existing Seminoe Reservoir 
at normal maximum water surface elevation of 6,357 feet; (8) a 
transformer cavern containing 18 kilovolt (kV) generator step-up 
transformers for each unit, and a gas-insulated switchgear switchyard; 
(9) a 765-foot-long horizontal tunnel transmitting power from the 
transformer gallery to a vertical cable shaft up to a take-off 
structure at the surface, and then via two separate, 500 kV, overhead 
primary transmission lines extending to the 500 kV interconnection at 
Aeolus Substation, approximately 30 miles to the southeast of the 
project; (10) an approximately 32-foot-diameter main access tunnel 
providing access to the machine hall; (11) a 15-foot-wide, 16-foot-high 
surge chamber access tunnel lined with shotcrete; (12) a 2.6-mile-long 
new access road around the upper reservoir; (13) a new 40-foot-wide 
road to the main access tunnel portal starting from a proposed new 
bridge over the tailrace of Seminoe Dam; and (14) appurtenant 
facilities. Additionally, portions of Western Area Power 
Administration's existing Miracle Mile-Snowy Range 1 115 kV and Miracle 
Mile-Snowy Range 2 230 kV transmission lines would be relocated around 
the upper reservoir. Furthermore, the existing Bennett Mountain Road 
(also called Dry Lake Road) would be upgraded (i.e., widened to 24 
feet) to support construction and maintenance of the proposed upper 
reservoir and realigned in places to reduce steep grades and avoid 
wetlands. The powerline road from Hanna would serve as the main access 
route to the lower intake and gate shaft area. BCH also proposes to 
upgrade a small section of the existing rough, single-track road from 
the proposed gate shaft location to the surge chamber access tunnel 
exit.
    BCH proposes to draw 13,400 acre-feet of water from Seminoe 
Reservoir to initially fill the new upper reservoir and would need 672 
acre-feet of water each year to replenish water lost through 
evaporation. Once the upper reservoir is filled, approximately 10,800 
acre-feet could be cycled between the upper reservoir and Seminoe 
Reservoir each day and the project would be capable of generating 2,916 
gigawatt-hours per year.
