CX-020293: REVISED Eugene-Alderwood 115-kV Transmission Line Insulator Replacements

BPA proposes to replace non-ceramic insulators (NCIs) with ceramic insulators on sections of the Eugene-Alderwood, Albany-Eugene, Parker Tap, and Junction City Tap 115-kV transmission lines located in the BPA’s Eugene district. The existing NCIs are subject to flashover and are beyond their designated end of life span. Structures requiring insulator replacements are primarily located along the median between Highway 99 and railroad tracks. The work will occur between BPA’s Eugene Substation, located in the city of Eugene, and the intersection of Oregon State Highway 99 and Prairie Road. Land use in the area includes urban/industrial and agriculture. Replacing the insulators would be done using a combination of line trucks, trailers, and light duty trucks. All structures have good access and insulator replacement does not require any ground disturbance.
