DOE/EA-2291: South of Tri-Cities Reinforcement Project; Benton County, Washington

Bonneville Power Administration (BPA) prepared an environmental assessment (EA) for the South of Tri-Cities Reinforcement Project (DOE/EA-2291) in Benton County, Washington. The proposed substation near County Well Road would tie into an existing 500-kV transmission line and convert the voltage to 115-kV for local transmission along the new approximately 18-mile-long transmission line to the existing Badger Canyon Substation in Richland, Washington. Up to 0.8 mile of the proposed 115-kV transmission line would cross land managed by the U.S. Bureau of Land Management -Spokane Border Field Office (BLM-Spokane). Badger Canyon Substation would be reconfigured and upgraded to incorporate the new transmission line. Fiber optic cable would be added to the new transmission line, as well as along other existing transmission lines in the area, to improve operational communication and control.
