n. Project Description: The existing Wyre Wynd Hydroelectric Project consists of: (1) A concrete-encased masonry dam that includes the following sections: (a) A 473-foot-long, 19-foot-high spillway section with a crest elevation of 95.3 feet National Geodetic Vertical Datum of 1929 (NGVD) and 2-foot-high flashboards at an elevation of 97.3 feet NGVD at the top of the flashboards; (b) a left abutment section; and (c) a right abutment section; (2) a 333-acre impoundment with a normal elevation of 97.3 feet NGVD; (3) a 100-foot-long, 25-foot-wide headgate structure with five 10.5-foot-wide, 11.5-foot-high sluice gates; (4) a 170-foot-long, 50-foot-wide forebay with five 13-foot-high, 9.5-foot-wide flood gates, a 110-foot-long overflow weir, and two 13-foot-high, 9.5-foot-wide low-level outlet gates; (5) a powerhouse intake structure located at the downstream end of the forebay that includes: (a) A 38.2-foot-long, 20- to 21.3- foot-wide trashrack with 2.6-inch clear-bar spacing; (b) a 16-foot-long, 12-foot-diameter steel penstock that provides flow to a 2.7-megawatt (MW) S-type Kaplan turbine-generator unit located inside of a 75-foot-long, 30-foot-wide concrete powerhouse; and (c) a 450-foot-long, 60-foot-wide tailrace; (6) a minimum flow unit intake structure that branches off of the right side of forebay approximately 35 feet downstream of the headgate structure, and that includes: (a) A 20-foot-long, 9-foot-wide trashrack with 1.5-inch clear-bar spacing; (b) a 40-foot-long, 4-foot-diameter steel penstock that provides flow to a 0.08-megawatt (MW) propeller-type turbine-generator unit located outside; and (c) a 10-foot-long, 30-foot-wide tailrace; (7) two generator leads connecting the turbine-generator units to the local electric distribution system; and (8) appurtenant facilities. The project creates an approximately 400-foot-long bypassed reach of the Quinebaug River.

The current license requires an instantaneous minimum flow of 120 cubic feet per second (cfs), or the inflow, whichever is less, downstream of the dam to protect fish and wildlife resources in the Quinebaug River.

The project had an average annual generation production of approximately 11,000,000 kilowatt-hours from 2003 through 2015.

Aspinook proposes to: (1) Operate the project in run-of-river mode; (2) provide an 84-cfs minimum flow to the bypassed reach; and (3) provide upstream and downstream fish passage.
