# PacifiCorp; Notice of Preliminary Permit Application Accepted for Filing and Soliciting Comments, Motions To Intervene, and Competing Applications
On October 13, 2021, PacifiCorp filed an application for a preliminary permit, pursuant to section 4(f) of the Federal Power Act (FPA), proposing to study the feasibility of Long Ridge Pumped Storage Project to be located about 3 miles West of Mona, 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 consist of the following: (1) A new upper reservoir for alternative 1 with a surface area of 277 acres, a total storage capacity of 3,672 acre-feet at a normal maximum operating elevation of 6,500 feet average mean sea level (msl); (2) a new upper reservoir for alternative 2 and 3 with a total storage capacity of 2,798 acre-feet at a normal maximum operating elevation of 6,830 feet msl; (3) a new lower reservoir for alternative 1 with a surface area of 90 acres at a normal maximum operating elevation of 5,220 feet msl; (4) a new lower reservoir for alternative 2 with a surface area of 98 acres at a normal maximum elevation of 5,320 feet msl; (5) a new lower reservoir for alternative 3 with a surface area of 98 acres at a normal maximum elevation of 5,115 feet msl; (6) a 14,784-foot-long tunnel penstock, with a hydraulic head of 1,280 feet, connecting the upper and lower reservoirs to the powerhouse for alternative 1; (7) a 16,368-foot-long tunnel penstock, with a hydraulic head of 1,665 feet, connecting the upper and lower reservoirs to the powerhouse for alternative 2; (8) a 17,424-foot-long tunnel penstock, with a hydraulic head of 1,665 feet, connecting the upper and lower reservoirs to the powerhouse for alternative 3; (9) a new underground powerhouse that would be sited along the western shore of the lower reservoir for alternative 1, 2, and 3 containing three turbine-generator units with a total rated capacity of 500 megawatts; (10) a new 0.8-mile-long, 230-kilovolt (kV) transmission line connecting the powerhouse to PacifiCorp's existing Mona substation for alternative 1; (11) a new 1.2-mile-long, 345-kV transmission line connecting the powerhouse to PacifiCorp's existing Clover substation for alternatives 2 and 3; and (12) appurtenant facilities. The estimated annual power generation at the Long Ridge Pumped Storage would be 1,460 gigawatt-hours.
