[Project No. 13841-000]


County of DuPage; Notice of Preliminary Permit Application 
Accepted for Filing and Soliciting Comments, Motions To Intervene, and 
Competing Applications

December 10, 2010.
    On September 21, 2010, the County of DuPage, Illinois, filed an 
application for a preliminary permit, pursuant to section 4(f) of the 
Federal Power Act (FPA), proposing to study the feasibility of the 
Elmhurst Quarry Pumped Storage Project (Elmhurst Quarry Project or 
project) to be located on Salt Creek, near Elmhurst City, DuPage 
County, Illinois. The sole purpose of a preliminary permit, if issued, 
is to grant the permit holder priority to file a license application 
during the permit term. A preliminary permit does not authorize the 
permit holder to perform any land-disturbing activities or otherwise 
enter upon lands or waters owned by others without the owners' express 
permission.
    The proposed project would consist of the following: (1) A surface 
quarry (upper reservoir) having a total storage capacity of 8,145 acre-
feet at a normal maximum operating elevation of 667 feet mean sea level 
(msl) and a usable capacity of 7,465 acre-feet; (2) an upper inlet/
outlet structure equipped with trash racks and one or two slide gates 
for isolating and dewatering the penstock; (3) an 870-foot-long, 28-
foot-diameter penstock consisting of both shaft and tunnel segments and 
extending between the upper inlet/outlet and the pump/turbines below; 
(4) an underground mine (lower reservoir) 250 feet below the bottom of 
the upper reservoir having a total/usable storage capacity of 7,465 
acre-feet at normal maximum operation elevation of 210 feet msl; (5) a 
powerhouse with approximate dimensions of 185 feet long by 80 feet wide 
by 120 feet high and containing two vertical Francis reversible pump/
turbine-motor/generator units rated for 125 megawatts each at 415 feet 
of net head; (6) a 120-foot-long, 28-foot-diameter tailrace tunnel 
connecting the pump/turbine draft tubes with the lower inlet/outlet; 
(7) a lower inlet/outlet structure equipped with one or two slide gates 
for isolating and dewatering the tailrace tunnel; (8) a substation 
containing step-up transformers, circuit breakers, and disconnect 
switches; (9) an underground 2-mile-long, 138-kilovolt (kV) 
transmission line extending from the project substation to an overhead 
138-kV transmission line owned by Commonwealth Edison (the point of 
interconnection); (10) a switchyard constructed at the point of 
interconnection; and (11) appurtenant facilities. The estimated annual 
generation of the Elmhurst Quarry Project would be 708.5 gigawatt-
hours.
