    i. FERC Contact: Allan Creamer at (202) 502-8365, or at 
[email protected].
    j. This application is not ready for environmental analysis (EA) at 
this time.
    k. Project Description: The Wallace Dam Project consists of: (1) A 
2,395-foot-long, 120-foot-high dam, consisting of (i) a 347-foot-long 
west earth embankment, (ii) a 300-foot-long west concrete non-overflow 
section, (iii) a 266-foot-long concrete spillway with five Tainter 
gates, each 48 feet high by 42 feet wide with a discharge capacity of 
35,000 cubic feet per second (cfs), (iv) a 531.4-foot-long powerhouse 
intake section, protected by trashracks having a clear bar spacing of 
9.5 to 10.5 inches and leading to six penstocks with a maximum diameter 
of 25.5 feet, (v) a 226-foot-long east concrete non-overflow section, 
(vi) a 725-foot-long east earth embankment, and (vii) two saddle dikes, 
located east of the dam, totaling about 900 feet in length; (2) an 
18,188-acre reservoir (Lake Oconee) at an elevation of 435.0 feet Plant 
Datum (where Plant Datum equals mean sea level (NAVD88) minus 0.20 
feet); (3) a powerhouse integral with the dam that contains six 
turbine/generator units (two conventional generating units and four 
reversible pump units, with a total installed capacity of 321.3 
megawatts; (4) a 20,000-foot-long tailrace that flows into Lake 
Sinclair, which serves as the lower reservoir for the Wallace Dam 
Project; (5) transmission facilities that consist of (i) 13.8-kilovolt 
(kV) generator leads, (ii) two 13.8/230-kV step-up transformers, (iii) 
a 230-kV substation, and (iv) a 15.67-mile-long transmission line that 
extends from Wallace Dam west to a switching station near Eatonton, 
Georgia; and (6) appurtenant facilities.
    The Wallace Dam Project is a pumped storage project, generating 
390,083 megawatt-hours of electricity annually. Water for generation at 
Wallace Dam comes from inflow, plus storage in Lake Oconee. The project 
generates during peak power demand hours to meet the electrical system 
demand. Water that is not used for generation at the downstream 
Sinclair Project (FERC No. 1951), remains in Lake Sinclair for a few 
hours before being pumped back into Lake Oconee. Pumpback operation 
occurs at night, when electrical system demand is low (off-peak hours). 
For normal day-to-day operation, Lake Oconee fluctuates between 
elevations 435.0 and 433.5 feet Plant Datum, resulting in an average 
daily fluctuation of 1.5 feet. The Wallace Dam Project discharges 
directly into Lake Sinclair, with no intervening riverine or bypassed 
reach. Generation typically is the highest during the summer months, 
where Wallace Dam generates for about 7 to 8 hours during the afternoon 
peak demand period. During the fall and winter months, generation 
typically last 5 to 6 hours.
    During drought periods, the Wallace Dam Project supports the 
minimum flow requirements of the downstream Sinclair Project. When the 
Sinclair Project's calculated inflow drops below its minimum flow 
requirement of 250 cfs, water is released from Lake Oconee to maintain 
Lake Sinclair at the minimum level necessary for safe pumpback 
operation at Wallace Dam, which is 338.2 feet Plant Datum.
