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

    On March 7, 2018, the Flat Canyon 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 Flat Canyon Pumped 
Storage Project (Flat Canyon Project or project) to be located in Flat 
Canyon, near the City of Elsinore, Sevier County, Utah. 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 would be a closed-loop pumped storage 
hydropower facility that consists of the following: (1) A 37-acre upper 
reservoir having a total storage capacity of 1,800 acre-feet at a 
normal maximum operating elevation of 6,930 feet mean sea level (msl); 
(2) a 55-foot-high, 550-foot-long zoned earth/rockfill or concrete-
faced upper reservoir dam; (3) a 55-foot-high, 525-foot-long zoned 
earth/rockfill or concrete-faced second upper reservoir dam; (4) a 
1,350-foot-long, 15-foot-diameter low-pressure headrace tunnel either 
unlined or lined concrete-lined; (5) a 6,850-foot-long, 15-foot-
diameter high-pressure headrace tunnel lined with either concrete or 
steel; (6) a 220-foot-long, 60-foot-wide, 120-foot-high powerhouse 
housed in an underground cavern and accessed via a 2,600-foot-long, 18-
foot-diameter access tunnel, housing two variable-speed reversible 
pump/turbine-motor/generator units rated for 150 megawatts each at 
1,370 feet maximum gross head; (7) a 2,400-foot-long, 17.5-foot-
diameter tailrace tunnel lined with concrete; (8) a 37-acre lower 
reservoir having a total storage capacity 1,800 acre-feet at a normal 
maximum operating elevation of 5,630 feet msl; (9) a 75-foot-high, 850-
foot-long zoned earth/rockfill or concrete-faced lower reservoir dam; 
(10) a 13-mile-long, 230-kilovolt (kV) transmission line extending from 
the powerhouse that would follow an existing transmission corridor to 
the Sigurd Substation owned by Rocky Mountain Power, or, if possible, a 
direct connection to Rocky Mountain Power's Sigurd-Red Butte No. 2 345-
kV line adjacent to the project (the point of interconnection); and 
(11) appurtenant facilities. The estimated annual generation of the 
Flat Canyon Project would be 525.6 gigawatt-hours.
