BURBANK, Wash. – The U.S. Army Corps of Engineers’ Ice Harbor Lock and Dam hosted a multi-agency, environmental response drill on Thursday, Oct. 6. In the tabletop exercise, the Corps’ Walla Walla District worked with other agencies to respond to a simulated railroad oil spill just upstream of the dam. The Corps improves its response to spills by participating in ongoing multi-agency exercises and communication. This exercise followed a Washington State Department of Ecology (Ecology) Geographical Response Plan (GRP) update. Ecology recently revised the plan for the Ice Harbor area. The Corps’ mission during a spill is to protect the environment including downstream communities, parks, marinas and fish passage facilities.
