    j. This application is not ready for environmental analysis at this 
time.
    k. Project Description: The existing project consists of: (1) a 74-
foot-high, 881-foot-long concrete multiple arch-buttress dam consisting 
of the following sections: (a) a 236-foot-long concrete ogee spillway 
section with a crest elevation of 1,517.3 feet National Geodetic 
Vertical Datum of 1929 (NGVD29), and 3-foot-high flashboards at an 
elevation of 1,520.3 feet NGVD29 at the top of the flashboards; (b) a 
265-foot-long concrete non-overflow section with two, 7-foot-diameter 
cylindrical discharge gates; (c) a 120-foot-long earthen dike north 
abutment; and (d) a 260-foot-long earthen dike south abutment; (2) a 
27-foot-high, 900-foot-long earthen containment dike (Abbott Brooke 
Dike) located two miles upstream of the dam; (3) an impoundment 
(Aziscohos Lake) with a maximum water surface elevation of 1,520.3 feet 
NGVD29; (4) an intake structure consisting of a modified log sluice 
with stoplogs and a 96-inch butterfly valve in the non-overflow section 
of the dam; (5) a 2,462-foot-long, 8-foot-diameter steel penstock that 
provides flow to a 5.311-megawatt vertical Kaplan turbine-generator 
unit located in a concrete powerhouse; (6) a 60-foot-long tailrace; (7) 
a 12.47/34.5- kilovolt (kV) step-up transformer and a 23.5-mile long, 
34.5-kV transmission line connecting the project generator to the 
regional grid; and (8) appurtenant facilities. The project creates an 
approximately 2,400-foot-long bypassed reach of the Magalloway River.
    The project is operated as a seasonal storage reservoir as part of 
the Androscoggin River Storage System. The current license requires 
ARCO to provide a minimum flow of 130 cubic feet per second (cfs) 
downstream of the powerhouse from the start of spring refill through 
September 15. The minimum flow is increased to 214 cfs from September 
16 to the start of spring refill each year. The current license 
requires that 50 cfs of the required minimum flow, be released from the 
Aziscohos Dam into the bypassed reach of the Magalloway River. The 
current license also requires that a whitewater flow of 900 cfs be 
released during the 4th weekend of June, 1st weekend of July, and 1st 
weekend of September; and a whitewater flow of 1,200 cfs be released on 
the 2nd weekend of July, and the 3rd and 4th weekend of August.
    The minimum and maximum hydraulic capacities of the powerhouse are 
290 cfs and 623 cfs, respectively. The average annual generation of the 
project was approximately 30,788 megawatt-hours from 2012 through 2022.
    ARCO is not proposing any changes to project facilities or 
operation at this time.
