70-foot-wide powerhouse that contains four reversible pump turbine-
generator units with a total installed capacity of 1,166.8 MW; (15) 
four 25-foot-long, 11-foot-diameter draft tubes that transition to a 
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-

pipe-type cables from the transformers to the Northfield Switching 
Station; (20) a 650-foot-long, 15-foot-deep fixed-position fish barrier 
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.
