    k. The Project Description: The Conowingo Project consists of a 
concrete gravity dam with a maximum height of approximately 94 feet. 
The dam consists of a 1,225-foot-long non-overflow gravity section, a 
2,385-foot-long ogee shaped spillway section, a 950-foot-long intake-
powerhouse section, and a 100-foot-long non-overflow gravity section. 
The spillway consists of a 2,250-foot-long section with a crest 
elevation of 86.0 feet, and a 135-foot-long section with a crest 
elevation of 98.5 feet. The spillway is fitted with 50 Stoney-type 
crest gates and two regulating gates. Each Stoney crest gate is 22.5 
feet high by 38 feet wide and has a discharge capacity of 16,000 cubic 
feet per second (cfs) at a reservoir elevation of 109.2 feet. The two 
regulating gates are 10 feet high by 38 feet wide and have a discharge 
capacity of 4,000 cfs per gate at a reservoir elevation of 109.2 feet.
    Conowingo dam impounds the Susquehanna River, forming Conowingo 
reservoir (Conowingo pond) that extends 14 miles upstream from the dam. 
Total storage in the 9,000-acre reservoir is approximately 310,000 
acre-feet, and total useable storage is about 71,000 acre-feet at the 
normal full pool elevation of 109.2 feet. The elevation of the normal 
river surface below the dam is approximately 20.5 feet. The impoundment 
provides approximately 89 feet of gross head for power generation 
purposes.
    The power plant is integral with the dam and is composed of 13 
turbine-generator units, draft tubes, and transformer bays. The first 
seven turbine-generating units (1-7) are completely enclosed within the 
powerhouse, and the last four units (8-11) are located outside. The 
hydraulic equipment for units 1-7 consists of Francis-type single 
runner hydraulic turbines. The hydraulic equipment for units 8-11 
consists of four mixed-flow Kaplan-type hydraulic turbines. Units 1, 3, 
4, 6 and 7 have 47.7-MW generators; Units 2 and 5 have 36.0-MW 
generators; and Units 8-11 have 65.6-MW generators. Additionally, two 
house turbines provide station service and ``black-start'' capability 
with each unit having a 1.6-MW generator. Water flowing through the 
turbines is discharged via the draft tubes into the tailrace 
immediately downstream of the dam.
    Electricity generated at the project is transmitted by two 
individual 220-kilovolt (kV) transmission lines extending from the 
project substation to East Nottingham.
    The Conowingo Project has an authorized nameplate generating 
capacity of 573 MW and generates an average of 1,836,125 MWh annually. 
Exelon is not proposing any new or upgraded facilities or structural 
changes to the project at this time. Also, Exelon has engaged 
interested stakeholders to participate in the development of a 
comprehensive settlement agreement based on collaborative negotiation 
of specific terms and conditions for the new Conowingo license.
    l. Locations of the Application: A copy of the application is
