Proposed Action

BPA has decided to construct the Big Eddy-Knight Transmission Project in Wasco County, Oregon and Klickitat County, Washington. This project consists primarily of constructing a new, approximately 28-mile-long, 500-kilovolt (kV) transmission line and ancillary facilities between BPA's existing Big Eddy Substation in The Dalles, Oregon, to a proposed new Knight Substation that would be connected to an existing BPA line about 4 miles northwest of Goldendale, Washington.

The Big Eddy-Knight Transmission Project will respond to requests for transmission service in the region by increasing transmission capability of the electrical system. For the transmission line, BPA has decided to build East Alternative Option 3, which was identified in the final EIS as the preferred alternative for the transmission line route. For the first 14 miles, the line will use double-circuit towers (combining the new line and an existing line on one set of towers) mostly on existing right-of-way. The remaining 14 miles of the new line will be built with single-circuit towers in newly-established transmission line right-of-way. BPA has also decided to build the small (about 1 mile) realignment of the East Alternative on the Oregon side of the Columbia River, as described in the final EIS. For the proposed new Knight Substation, BPA has decided to build Knight Substation on Site 1, which is on private property about 0.5 mile west of Knight Road. For the fiber optic cable necessary for system communications, BPA has decided to build the Loop Back Option, which will string fiber optic cable on the new transmission towers from BPA's Big Eddy Substation to the new Knight Substation and back again. The project also includes new equipment at BPA's existing Big Eddy and Wautoma substations. BPA considered three transmission line alternatives, two Knight Substation sites, two fiber optic cable options, and the No Action Alternative.

Conditions of Approval

BPA will be responsible for the execution of all mitigation measures. All the mitigation measures described in the draft EIS and updated in the final EIS that apply to the East Alternative, Knight Substation Site 1, and the Loop Back Option are adopted. A complete list of these measures the attached Mitigation Action Plan. Also included as part of the Mitigation Action Plan are possible measures to be implemented on DNR lands as negotiated by the Washington Statewide Rights‐of‐Way Memorandum of Agreement or other agreements. The Mitigation Action Plan is provided as part of the ROD and available at: http://efw.bpa.gov/environmental_services/Document_Library/Big_Eddy-Knight/pdf/rod-20110916-Big-Eddy-Knight-Transmission-Project.pdf
