Bonneville Power Administration Proposed Fiscal Year 1979 Program. Facility Location Supplement: Southwest Oregon Service, Buckley-Summer Lake 500 KV Line. Final Supplement; Final Environmental Impact Statement

摘要

The Bonneville Power Administration (BPA) proposes to construct transmission facilities which will coordinate with the Midpoint-Malin 500-kV line to be constructed by the Pacific Power and Light (PP and L) Company. These are: (1) the 156-mile (250 km) Buckley-Summer Lake 500-kV line which is scheduled to be energized in the fall of 1982, (2) the 84-mile (135 km) LaGrande-McNary 500-kV line, (3) a 44-mile (70 km) McNary-Slatt 500-kV line to be constructed by BPA when additional generation is added at McNary. This coordinated project will facilitate the transfer of electric power from the Pacific Northwest to BPA customers in southern Idaho and Utah. In addition, it allows power generated in Wyoming to be delivered to the Pacific Northwest, including southwest Oregon. It would also reinforce the existing PNW-PSW Intertie within the State of Oregon. Finally, the BPA facilities provide additional transmission capacity for wheeling services and other transactions needed in the region. Additional discussion of the planning for the project appears in the Final Facility Planning Supplement for Southwest Oregon Service. This document assesses the environmental impacts of the proposed 156-mile Buckley-Summer Lake 500-kV transmission line; the proposed Buckley Substation near Maupin, Oregon; and the proposed Summer Lake Substation near Silver Lake, Oregon.
