Keeler to Tillamook Transmission Line Rebuild (DOE/EA-1931)

Washington and Tillamook counties, Oregon


    BPA has made the decision to rebuild the Keeler to Tillamook 115-kilovolt (kV) transmission line. The 58 mile long wood-pole line extends from Hillsboro to Tillamook, Oregon. Based on the final environmental assessment (EA), BPA is issuing a finding of no significant impact (FONSI) and has made a decision to proceed with the project. The rebuild includes replacement of all wood-pole structures over 10 years in age, including cross arms, cross braces, guy wires, anchors, insulator assemblies, switches, and overhead conductor. The rebuild will enable BPA to maintain reliable electric service and avoid risks to the public and worker safety. The line will continue to operate at 115-kV.


    BPA decided to rebuild the Keeler to Tillamook transmission lines based on the final EA and FONSI. The final EA includes a mitigation action plan that outlines the mitigation measures that are being implemented. Construction is planned to begin in April 2014 and will be completed in January 2015.
