Army Corps extends comment period on proposed BPA line



The U.S. Army Corps of Engineers has extended its comment period on a proposed transmission line through Southwest Washington, matching an earlier decision by the Bonneville Power Administration.

The Army Corps will now accept comments until March 25 — the same day BPA’s formal comment period ends. Both had been set to continue through March 1 before the extensions.

BPA has proposed building a 500-kilovolt transmission line through Clark and Cowlitz counties, stretching nearly 80 miles between Castle Rock and Troutdale, Ore. The agency identified its preferred route for the line in November, detailed in a draft environmental impact statement. The proposed line would cost an estimated $459 million to build, according to BPA.

The Army Corps is one of the agencies that must grant permits for the project to move forward. Construction could begin as early as 2015, according to BPA.
