The Public Utility District No. 1 of Snohomish County in Washington is seeking a license for a new, 6-MW hydroelectric project, said the Federal Energy Regulatory Commission in a notice to be published in the Aug. 23 Federal Register.
The project would be on the Calligan Creek, near the town of North Bend, King County, Wash. The proposed project would not occupy any federal lands.
The Calligan Creek Hydroelectric Project would consist of the following new facilities: an approximately 110-foot-long, 14-foot-high diversion with a 45-foot-long, 8-foot-high spillway; a 1.04-acre-foot impoundment; a 200-square-foot fish screen with 0.125-inch-wide openings; a 1.20-mile-long, 41-inch-diameter penstock; a powerhouse containing a single 6-MW two-jet horizontal-shaft Pelton turbine/generator; a 135-foot-long rip-rap-lined tailrace channel discharging into Calligan Creek; 300 feet of access roads in addition to existing logging roads; and a 2.5-mile-long, 34.5-kV buried transmission line connecting to the existing Black Creek Hydroelectric Project (P-6221) switching vault.
The project is estimated to provide 20.7 gigawatt-hours annually.
