CX-012111: Categorical Exclusion Determination

B3S4-White Bluffs Number 1 and Benton-B3S4 Number 1 Transmission Line Reroute
CX(s) Applied: B4.13
Date: 04/02/2014
Location(s): Washington
Offices(s): Bonneville Power Administration

Bonneville Power Administration (BPA) is proposing to remove three transmission structures and relocate one structure on U.S. Department of Energy (DOE)-Hanford property in order to bypass a substation. As part of DOE-Hanford’s Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) clean-up project in the 300 Area of Hanford, DOE-Hanford will retire and remove its B3S4 Substation. BPA’s B3S4-White Bluffs Transmission line and the Benton-B3S4 Transmission Line currently terminate at the B3S4 Substation. Consequently, with the removal of the substation, BPA would need to connect the two lines and bypass the former substation site.
