          - [Project No. 13360-000]

On January 29, 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 Ruby River Reservoir Hydroelectric Project, which would be located at the existing Ruby River dam on Ruby River near the town of Alder in Madison 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 846-foot-long, 111-foot-high earthen dam; (2) an existing reservoir with a surface area of 970 acres and a storage capacity of 37,612 acre-feet at the normal water surface elevation of 5,392 feet mean sea level; (3) an existing concrete outlet works tunnel, which would be lined with steel; (4) a new 84-inch-diameter, 180-foot-long steel penstock in the tunnel; (5) a new 84-inch-diameter, 20-foot-long penstock extending from the tunnel to the powerhouse; (6) a new powerhouse containing two generating units with a combined installed capacity of 2.2 megawatts; (7) a new tailrace discharging flows into the Ruby River at the base of the dam; (8) a new substation; (9) a new 15-kilovolt, 2-mile-long transmission line; and (10) appurtenant facilities. The proposed project would have an average annual generation of 10 gigawatt-hours.
