          - [Project No. 13700-000]

On April 5, 2010, Hydrodynamics, Inc. 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 Mill Coulee Hydroelectric Project to be located in Cascade County, Montana near Fairfield, Montana on the Mill Coulee canal, a water distribution facility of the U.S. Bureau of Reclamation's Sun River Project. 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 will consist of the following: (1) A new 3-foot-high, 20-foot-wide, one-foot-thick diversion structure with a flood gate and trash rack; (2) a 2,020-foot-long, 48-inch-diameter polyethylene penstock; (3) a 60-foot-long, 60-foot-wide powerhouse; (4) a turbine/generator unit with a capacity rating of 900 kilowatts; (5) a 3,750-foot-long clay-lined tailrace canal returning flows to the Mill Coulee canal; and (6) a 69-kilovolt, 3,400-foot-long transmission line.

Annual energy production is estimated to be 2.25 gigawatt-hours.
