E9-10101. Hydrodynamics, Inc.; Notice of Preliminary Permit Application Accepted for Filing and Soliciting Comments, Motions To Intervene, and Competing Applications

April 23, 2009.

On February 11, 2009, Hydrodynamics, Inc. filed an application for a preliminary permit, pursuant to section 4(f) of the Federal Power Act, proposing to study the feasibility of the Tongue River Reservoir Hydroelectric Project, which would be located at the existing Tongue River Reservoir dam on the Tongue River near the town of Decker in Bighorn County, Montana. 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) An existing 1,824-foot-long, 91-foot-high earthen dam; (2) an existing reservoir with a surface area of 3,700 acres and a storage capacity of 79,071 acre-feet at the normal water surface elevation of 3,138 feet mean sea level; (3) an existing concrete outlet works tunnel, which would be lined with steel; (4) a new 84-inch, 520-foot-long steel penstock in the tunnel; (5) a new 40-foot-long penstock extending from the tunnel to the powerhouse; (6) a new powerhouse containing two generating units with a combined installed capacity of 2.0 megawatts; (7) a new tailrace discharging flows into the Tongue River at the base of the dam; (8) a new substation; (9) a new 125-kilovolt, 8.5-mile-long transmission line; and (10) appurtenant facilities. The proposed project would have an average annual generation of 11.0 gigawatt-hours.
