    k. The Project Description: The Muddy Run Pumped Storage Project 
consists of four dams. The main dam is a rock-filled structure across 
the Muddy Run ravine with a central impervious core, a maximum height 
of approximately 260 feet and a total length of 4,800 feet. The east 
dike is a zoned-earth and rock-filled embankment with a maximum height 
of approximately 12 feet and a total length of 800 feet. The recreation 
pond dike is a zoned-earth and rock-filled embankment with a maximum 
height of approximately 90 feet and a total length of 750 feet. The 
canal embankment has a maximum height of approximately 35 feet. Total 
storage in the 900-acre Muddy Run reservoir (upper reservoir) is 
approximately 60,000 acre-feet and the total useable storage is 
approximately 35,500 acre-feet at the maximum pool elevation of 520 
feet. The maximum pool elevation is approximately 411 feet above the 
normal elevation of Conowingo pond. Conowingo pond (lower reservoir) 
has a surface area of 9,000 acres and design storage of approximately 
310,000 acre-feet at the normal full pool elevation of 109.2 feet.
    The main spillway is a non-gated concrete ogee-type structure that 
is 200 feet long, 20 feet high and with crest elevation of 521 feet, 
which is directed to a vegetated natural ravine. The recreation pond 
spillway is a rock-cut channel approximately 140 feet wide and with a 
crest elevation of 520 feet.
    The power intake facilities consist of four cylinder gates with 
trash racks in a cylindrical tower. Each intake supplies two units. 
Each intake leads to a 430-foot-deep vertical shaft then to a 
horizontal power tunnel, which divides into two sections. The power 
tunnel sections transition to a penstock that leads to one of the eight 
reversible pump-turbine units in the powerhouse. The power plant is 
constructed of concrete and is 133 feet wide and 600 feet long. It 
houses eight Francis turbines each equipped with a 100-MW generator. 
The powerhouse turbines each have a hydraulic capacity of 4,000 cfs, 
for a total discharge capacity from the powerhouse of 32,000 cfs. The 
pumping capacity of the pump turbines is 3,500 cfs each for a total 
powerhouse pumping capability of 28,000 cfs. Water flowing through the 
turbines is discharged via the draft tubes into the Susquehanna River 
adjacent to the powerhouse. The units are equipped with trash racks 
between the draft tube outlet and the river.
    Electricity generated at the project is transmitted by two 
individual 220-kV transmission lines extending from the project 
switching station approximately 4.25 miles to the Peach Bottom Atomic 
Power Station (PBAPS) North Substation located in York County.
    The Muddy Run Project has an authorized nameplate generating 
capacity of 800 MW and generates an average of 1,610,611 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 Muddy Run license.
