Start Preamble

On February 3, 2012, Hydro Development, LLC 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 Cascade Creek Hydroelectric Project (Cascade Creek Project or project) to be located on Swan Lake and Cascade Creek, near Petersburg, Alaska. 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) The existing Swan Lake with surface area of 574 acres and useable storage capacity of 22,500 acre-feet; (2) an outlet control structure consisting of a low-head weir and a 3-foot-high, 50-foot-wide crest gate; (3) a submerged siphon inlet with screens; (4) a tunnel and penstock system conveying flows from the lake siphon to the powerhouse including: (i) A 26-foot-long, 26-foot-wide, 98-foot-deep concrete lined vertical shaft containing 10-foot-diameter siphon piping and a siphon shutoff valve; (ii) a 12-foot-diameter, 12,700-foot-long unlined low pressure tunnel; (iii) a 14-foot-diameter, 1,320-foot-long unlined vertical shaft/vent; (iv) a 14-foot-diameter, 1,980-foot-long tunnel containing a 9-foot-diameter, 1,980-foot-long steel penstock; and (v) a 9-foot-diameter, 780-foot-long buried steel penstock; (5) a 140-foot-long, 80-foot-wide concrete and metal powerhouse with three 23.3-megawatt (MW), vertical-shaft Pelton turbine units having a total installed capacity of 70 MW; (6) a 450-foot-long, 40-foot-wide riprap-armored trapezoidal open-channel tailrace; (7) a new marine access facility, including a dock and barge landing ramp; (8) a 18.7-mile-long, 138-kilovolt transmission line consisting of buried, submarine, and overhead segments, with interconnection to the existing Scow Bay substation; and (9) appurtenant facilities. The estimated annual generation of the Cascade Creek Project would be 200 gigawatt-hours.
