[email protected].
    j. This application is not ready for environmental analysis at this 
time.
    k. Project Description: The existing project consists of: (1) a 
494-foot-long concrete gravity dam consisting of a 61-foot-high non-
overflow concrete abutment section and three overflow spillway sections 
46-foot-high and each topped by a 5-foot-high inflatable rubber dam; 
(2) a 268-acre impoundment; (3) a 78-foot-wide, 36-foot-high concrete 
intake structure with two concrete wing walls, a steel trashrack with 
one-inch bar spacing, and an embedded downstream fishway; (4) two 3-
foot-diameter steel penstocks and four 9-foot-diameter steel penstocks 
each running parallel to each other and extending underground from the 
dam to the powerhouse with lengths ranging from 382.9 to 389.3 feet; 
(5) a 154.6-foot-long, 93.5-foot-wide, and 55.7-foot-high, reinforced-
concrete and brick powerhouse located 400 feet downstream of the intake 
housing four horizontal Francis-type turbines with an installed 
capacity of 2,223 kilowatts (kW) each and four horizontal shaft 
generators rated at 1,800 kilowatts each as well as a double horizontal 
Francis-type turbine (i.e., minimum flow unit) with an installed 
capacity of 874 kW connected to a generator rated at 850 kW; (6) a 300-
foot-long, 34.5-kilovolt overhead transmission line; and (7) 
appurtenant facilities. Green Mountain Power Corporation also owns and 
maintains the following recreation facilities: Overlook Park, an access 
site to the impoundment, an access site to the powerhouse tailrace 
area, and a canoe portage.
    The downstream fish passage facility consists of two entrance gates 
each 3-feet-wide and 7.5-feet long located at the west end of the 
spillway. One entrance is located near the north end of the intake 
trashracks and the other is located closer to the center of the intake 
trashracks. The two entrances feed into a collection chamber behind the 
trashracks. The two collection chambers are connected via a 54-inch-
diameter, 67-foot-long steel pipe which transports fish to an open 
channel sluice down the adjacent spillway and into a plunge pool. The 
plunge pool water level is controlled by a concrete weir with a bell-
mouthed vertical slot with a 1-foot-wide opening which discharges flow 
into the bypassed reach.
    GMP currently operates the project in a modified daily peaking mode 
while raising and lowering the impoundment level a maximum of 3 feet 
but now proposes to operate the project in run-of-river mode year-round 
while maintaining the impoundment at an elevation of 274.7 feet (under 
normal flow conditions). GMP would continue to provide minimum flows of 
100 cubic feet per second (cfs) or inflow, if less, through the fish 
passage facility into the bypassed reach from April 15 through June 30 
and from September 15 through December 15 and 50 cfs or inflow, if 
less, into the bypassed reach the remainder the year. The project has 
an average annual generation of 35,498 megawatt-hours.
