CX-017564: PacifiCorp McNary Substation Interconnection (update to previous Categorical Exclusion issued on December 15, 2016)

Bonneville Power Administration is providing an interconnection to PacifiCorp at Bonneville Power Administration’s McNary Substation as described in the Categorical Exclusion issued for this project on December 15, 2016. Since issuance of the December Categorical Exclusion, interconnection design has been modified—Bonneville Power Administration will now also relocate and raise some transmission line structures to accommodate a PacifiCorp line route under Bonneville Power Administration’s lines near the substation, and a communication equipment vault will be installed outside the McNary substation perimeter.
