          - [Project No. 15044-000]

On September 10, 2020, Maysville PSH, 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 closed-loop Maysville Pumped Storage Project located in Mason County, Kentucky and Adams County, Ohio. 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 Maysville Pumped Storage Project would consist of the following:*                     (1) A 7,400-foot-long, 110-foot-high roller-compacted concrete ring dam; (2) an upper reservoir with a surface area of 65 acres and a storage capacity of 5,625 acre-feet; (3) a 630-foot-long, 18.5-foot-diameter concrete-lined, inclined headrace tunnel leading to; (4) a 1,020 foot-long, 18.5-foot-diameter high pressure, steel-lined vertical shaft connecting to; (5) three 100-foot-long, 10-foot-diameter steel penstocks; (6) a 400-foot-long by 75-foot-wide and 160-foot-high underground powerhouse containing three 167-megawatt reversible pump-turbines; (7) a 150-foot-long by 75-foot-wide and 44-foot-high underground transformer chamber; (8) a 3,200-foot-long, 21.6-foot-diameter concrete-lined tailrace conduit; (9) a lower reservoir created within excavated underground mine space in Mason County, Kentucky, with a surface area of 120 acres and a storage capacity of 5,556 acre-feet; and (10) a new 2.8-mile-long, 230 kilovolt (kv) transmission line, which would run underground from the transformer chamber through the existing mine for 1.2 miles, continue under the Ohio River through a 0.2-mile-long, 18-foot-diameter tunnel, and then run overhead for 1.4 miles to the point of interconnection with a 345-kV bus at the former Stuart Generating Station in Adams County, Ohio. The proposed project would have an estimated annual generation of 876,000 megawatt-hours.
