Start Preamble 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.
