EA-1366: Santiam-Bethel Tap 230 kV Transmission Line Project

Summary

Bonneville Power Administration prepared DOE/EA-1366 for the proposed rebuilding of the first 17 miles of the Santiam-Chemawa transmission line from Santiam Substation to the line’s connection to Portland General Electric’s Bethel Substation. The proposed rebuild would replace the existing single-circuit 230-kilovolt (kV) line with towers that could support two circuits (double-circuit) in the existing right-of-way.
