20-foot-long, 17-foot-diameter draft tube; (16) a 5,136-foot-long, 33-
foot-wide, 31-foot-high horseshoe-shaped tailrace tunnel; (17) 35-foot-
long, 40-foot-high trapezoid-shaped stoplogs with 74.3- to 99.5-foot-

guide net; and (21) appurtenant facilities.
The existing Turners Falls Hydroelectric Project operates in
peaking and run-of-river modes depending on inflows. The existing
license requires maintaining the impoundment between elevations 176.0
feet and 185.0 feet NGVD 29, and releasing a continuous minimum flow of
1,433 cubic feet per second, or inflow (whichever is less), from the
project. FirstLight did not propose any changes to operation of this
facility in its application.
The existing Northfield Mountain Pumped Storage Project generally
operates in pumping mode during low-load periods and generating mode
during high-load periods. In the summer and winter, the project
generally operates in a peaking mode in the
[[Page 31931]]
morning and late afternoon. In the spring and fall, the project may
operate in a peaking mode one or two times a day depending on
electricity demand. The existing license requires maintaining the upper
reservoir between elevations 938.0 feet and 1,000.5 feet NGVD 29 (i.e.,
a maximum reservoir drawdown of 62.5 feet).
FirstLight proposes to increase the maximum water surface elevation
of the upper reservoir to 1,004.5 feet NGVD 29 and decrease the minimum
water surface elevation of the upper reservoir to 920.0 feet NGVD 29
(i.e., a maximum reservoir drawdown of 84.5 feet) year-round.
