BPA needs to take action to ensure the integrity and reliability of the existing Bandon-Rogue transmission line (Figure 1-1). This 46-mile, 115-kilovolt1 (kV) transmission line, located between the BPA Bandon Substation and the BPA Rogue Substation in Coos and Curry counties,
is old, physically worn, and structurally unsound in places. The transmission line was originally built in the early 1950s by BPA. The original conductor has not been replaced and does not meet current standards. The poor condition of the transmission line creates risks to public and worker safety and could lead to unreliable electrical service.

This Mitigation Action Plan (MAP) is part of the Finding of No Significant Impact (FONSI) for the Walla Walla–Tucannon River Transmission Line Rebuild Project (Proposed Action). The Proposed Action involves rebuilding the 47-mile-long 115-kilovolt (kV) transmission line from
the existing Walla Walla Substation, located in the city of Walla Walla, Washington, to the existing Tucannon River Substation, located near the town of Dayton, Washington.
Bonneville Power Administration (BPA) announces its environmental findings on the Walla Walla–Tucannon River Transmission Line Rebuild Project (Rebuild Project or Proposed Action). The Rebuild Project involves rebuilding the existing Walla Walla–Tucannon River 115-kilovolt (kV) transmission line, which was built in 1940. The 47-mile-long transmission line is located in Walla Walla and Columbia counties in Washington, extending from the city of Walla Walla to near the town of Dayton.
This revision sheet documents the changes to be incorporated into the Walla Walla–Tucannon River Transmission Line Rebuild Project Preliminary Environmental Assessment (EA). With the addition of these changes, the Preliminary EA will not be reprinted and will serve as the Final EA.
DOE prepared this Supplemental EA to evaluate the potential environmental consequences of providing a financial assistance in a cooperative agreement with General Motors Limited Liability Company (LLC) (General Motors Company or GM). A supplement to the April 2010 EA was necessary due to the proposed building size increasing three fold as well as the addition of a parking lot and widening of a truck dock area. This building size increase is necessary to accommodate more manufacturing equipment and provide office space. If GM received the funding, they would construct a high-volume U.S. manufacturing facility to produce the first U.S.-manufactured electric motor components and assemble electric drive units for hybrid and electric vehicles.
