Description of Existing Structures The Flood Control Acts of 1944 and 1946 approved the construction of the Clark Canyon dam as part of the Reclamations Pick-Sloan Missouri River Basin Program, East Bench Unit. The approximately 2,950-foot-long zoned, earth-fill dam includes a concrete intake structure and conduit in the reservoir, a shaft house at the crest of the dam, a 9-foot-diameter conduit that discharges water to a concrete stilling basin, a gate chamber with four high pressure gates, two of which act as emergency gates, and an uncontrolled concrete spillway. 2. Description of Proposed Project Features Steel Liner – Clark Canyon Hydro proposes to install a new 8-foot-diameter steel penstock within the existing concrete conduit. The penstock will extend approximately 360 feet from the existing gate chamber to near the existing outlet works stilling basin. A trifurcation will then separate the flows into two steel penstocks (Powerhouse Penstocks) and one steel penstock, each of which will discharge into the existing outlet works stilling basin. Powerhouse Penstocks – Two steel 8-foot-diameter, 35-foot-long penstocks (the length includes the reducing sections) will convey flows from the trifurcation to the proposed powerhouse. 20150421-5044 FERC PDF (Unofficial) 4/20/2015 5:32:03 PM Directly upstream of the powerhouse, each of the two 8-foot-diameter penstocks will transition to a 6-foot diameter-steel penstock before entering the powerhouse. These penstocks will direct flows to both of the new turbines. Outlet Stilling Basin Discharge – The 8-foot-diameter steel penstock leaving the trifurcation to the outlet stilling basin will be approximately 10 feet long. A 7-foot-diameter fixed cone valve with a reducer will be installed at the end of the 8 foot diameter steel penstock for controlled discharge into the existing outlet works stilling basin. Powerhouse – The dimensions of the powerhouse will be approximately 41 feet by 62.5 feet. The powerhouse will contain two vertical Francis-type turbine/generator units with a combined generating capacity of 4.7 MW, and a combined discharge capacity of 700 cfs. The powerhouse will be a reinforced concrete substructure. Removable roof hatches will be provided for access to the equipment for maintenance. A crane will be provided for normal maintenance activities; however, a mobile crane will need to be brought to the site for installation and removal of the turbine/generator equipment. Controls, switchgear, and other electro-mechanical equipment will be located inside the powerhouse building. The powerhouse will include a control room. Draft Tubes and Tailrace – Water discharged from the turbines will pass through integral steel draft tubes (approximately 25 feet long, within the powerhouse). Each draft tube will transition into a concrete draft tube/tailrace section with integrated stop log channels outside the powerhouse, channels approximately 15-foot-wide by 17-foot-long and will discharge into the existing spillway stilling basin. Draft tubes outlets inside the tailrace will be configured with stop log slots for removable bulkheads to allow for dewatering. Powerhouse Substation – The powerhouse substation will be located northeast of the powerhouse (approximately 1,100 feet downstream of the powerhouse). The substation includes a 4.16 kV to 69 kV step-up transformer with switchgear on concrete pad foundations with containment and a grounding grid. Underground transmission line will be between the powerhouse and the powerhouse substation. Transmission –The new transmission line will run from the powerhouse substation approximately 7.9 miles to the Peterson Flat substation and will be adjacent to and within sections of the Highway 324 right-of-way (ROW) as shown in the attached map. The new line will consist of a single pole at a voltage of 69kV with an average span distance of 428 feet, and 13 poles per mile on a proposed 80 foot corridor. The proposed transmission line will cross Bureau of Reclamation (BOR), Montana State Land and run adjacent to private lands within the Beaverhead County Highway 324 Right of Way (ROW). 3. Existing Reservoir No proposed dams or reservoirs are included in the project. The existing Clark Canyon dam is federally owned. The reservoir has a capacity of 253,442 acre-feet and an active capacity of 126,117 acre-feet. The water surface area of the reservoir is 4,935 acres. 20150421-5044 FERC PDF (Unofficial) 4/20/2015 5:32:03 PM 4.
