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.
