OSTI ID:5301442
Bonneville Power Administation (BPA) proposes to construct 3.2 miles of 115-kV transmission line from a tap point on Tacoma City Light's Cowlitz-LaGrande 115-kV line to a new 115/12.5-kV, 15/20/25 MVA substation to be located about 1 mile northwest of Eatonville, adjacent to the Eatonville cutoff road. This plan was selected following initial consideration of five alternative plans for satisfying electrical needs in the project area and following agreement with BPA's customers on a vicinity for the substation site. The vicinity selected is midway between the two load centers and would require the least construction of distribution line. Subsequently, four alternative line routes and two substation sites have been evaluated. These alternatives provide a range of costs, engineering solutions, and potential environmental impacts. This evaluation led to the selection of one line route. This document describes possible environmental impacts of the proposed actions. 7 refs, 9 figs., 5 tabs.
