The Federal Energy Regulatory Commission on March 24 said in a notice that Wills Creek Hydro LLC, permittee for the proposed Wills Creek Dam Hydroelectric Project, has requested that its preliminary permit be terminated.
The permit was issued in January 2013, and would have expired on Dec, 31, 2015. The project would have been located at the U.S. Army Corps of Engineers’ Wills Creek Dam on Wills Creek, near Coshocton, Coshocton County, Ohio.
The preliminary permit will remain in effect until the close of business on April 23. But, if the commission is closed on this day, then the permit remains in effect until the close of business on the next day in which the commission is open. New applications for this site may not be submitted until after the permit surrender is effective.
The existing Corps facilities at this site include: the Wills Creek Lake, which has a surface area of 11,450 acres at a normal lake elevation of 742 feet and a maximum storage capacity of 196,000 acre-feet; a 1,950-foot-long, 87-foot-high earth fill dam; a 100-foot-high, 75-foot-wide, 25-foot-long intake structure located at the west abutment; and a 230-foot-long, 25-foot-wide, 25-foot-high concrete arch tunnel conduit.
The proposed project would have consisted of the following non-federal facilities: a 30-foot-wide, 30-foot-high, 2-foot-thick concrete diversion wall with a crest elevation of 742 feet equipped with two slide gates to release flood waters; a 30-foot-long, 106-inchdiameter steel penstock; a 30-foot-wide, 25-foot-long, 20-foot-high powerhouse located near the west wing wall of the Corps’ existing outlet channel and containing a pit/bulb propeller-type turbine/generator unit with a total capacity of 1 MW; and a 50-foot-long, 12.7-kV transmission line connecting the project to an existing distribution line owned by Cincinnati Gas and Electric. The estimated annual generation of the Wills Creek Dam Project would have been 5,728 megawatt-hours.
