The Commission's Rules of Practice and Procedure require all interveners filing documents with the Commission to serve a copy of that document on each person on the official service list for the project. Further, if an intervener files comments or documents with the Commission relating to the merits of an issue that may affect the responsibilities of a particular resource agency, they must also serve a copy of the document on that resource agency.
The application is not ready for environmental analysis at this time.
Project Description: The Phoenix Project consist of a concrete dam, known as the Phoenix Dam, that includes: (1) an approximately 90-foot-long, 55-foot-wide powerhouse that is integral with the dam and includes: (a) north and south intake openings with a trashrack with 1-inch clear bar spacing; and (b) two 1.59-MW vertical Kaplan turbine-generator units, for a total installed capacity of 3.18 MW; (2) a section with a 10-foot-long debris sluice gate and a 7-foot-long sluice gate that provides downstream fish passage; (3) a 163-foot-long, 14-foot-high ogee spillway with 1-foot-high flashboards that have a crest elevation of 362.42 feet North American Vertical Datum of 1988 (NAVD 88); (4) an approximately 206-foot-long section with four Tainter gates; (5) a 390-foot-long, 14-foot-high ogee spillway with 1-foot-high flashboards that have a crest elevation of 362.42 feet NAVD 88; and (6) a 107-foot-long section with two Tainter gates.
The 107-foot-long Tainter gate section of Phoenix Dam abuts Lock Island, which is a non-project feature that spans approximately 150 feet of the Oswego River. In addition, a non-project lock, known as the Phoenix Lock, spans approximately 45 feet of the Oswego River between Lock Island and the east shoreline of the Oswego River. Together, the Phoenix Dam, Lock Island, and Phoenix Lock create an impoundment that has a surface area of approximately 1,400 acres at 362.42 feet NAVD 88.
From the impoundment, water flows through the trashrack to a forebay, and then through the powerhouse. Water is discharged from the turbines to an approximately 120-foot-long tailrace that discharges to the Oswego River.
The project includes a trap and transport facility for the upstream passage of American eel that consists of an eel ramp and a plastic eel collection box located approximately 160 feet downstream of the project dam on the east shoreline of the Oswego River. The project also includes a downstream fishway that consists of the 7-foot-long sluice gate and a 4.8-foot-deep concrete plunge pool. Additionally, the project includes an aluminum walkway that provides access to the 206-foot-long Tainter gate section of the dam.
The project generators are connected to the regional electric grid by: a 4.16/34.5-kilovolt (kV) step-up transformer and a 230-foot-long, 34.5-kV underground transmission line.
The minimum and maximum hydraulic capacities of the powerhouse are 500 and 4,580 cubic feet per second (cfs), respectively. The average annual energy production of the Phoenix Project was 10,518 megawatt-hours from 2016 through 2023.
The current license requires Oswego Hydro to operate the project in a run-of-river mode and maintain a maximum impoundment surface elevation of 362.42 feet NAVD88. Oswego Hydro currently maintains the surface elevation of the impoundment between 361.92 feet and 362.42 feet NAVD 88. The current license also requires Oswego Hydro to: (1) release a year-round minimum flow of 300 cfs or inflow, whichever is less, to the Oswego River downstream of the project; and (2) when inflow is less than 1,900 cfs from June 1 through October 31, implement water quality monitoring and, if average tailwater dissolved oxygen drops below 5 milligrams per liter, provide mitigative flow releases for the protection of downstream water quality. Oswego Hydro provides upstream eel passage from June through October, using the trap and transport facility, and provides downstream fish passage year-round using the downstream fishway.
Oswego Hydro proposes to continue operating the project in a run-of-river mode and maintaining the surface elevation of the impoundment at 361.92 to 362.42 feet NAVD 88. Oswego Hydro proposes to continue releasing a year-round minimum flow of 300 cfs or inflow, whichever is less, to the Oswego River downstream of the project, but does not propose to continue water quality monitoring and mitigative flow releases when inflow is less than 1,900 cfs from June 1 through October 31. In addition, Oswego Hydro proposes to continue operating and maintaining the trap and transport facility and the downstream fishway for eel and fish passage. Oswego Hydro proposes to develop a fish passage operation and maintenance plan, implement a Bat and Bald Eagle Protection Plan that it filed in the application, and maintain an existing interpretative display and fencing for the protection of historic properties.
