Umatilla depot to deliver last chemical containers

HERMISTON -- The Umatilla Chemical Depot plans to take its final containers of chemical weapon agent to the Umatilla Chemical Agent Disposal Facility on Oct. 20.

A ceremony for workers is planned that day to mark delivery of the last mustard ton containers to the incineration facility.

The final shipment of chemical weapons will occur 70 years after the depot's formation Oct. 14, 1941. The depot received its first conventional weapons that year, and chemical weapons were brought to the depot in 1962 and have been stored there since.
