Umatilla Chemical Depot
The Umatilla Chemical Depot (UMCD), based in Umatilla, Oregon, was a U.S. Army installation in the United States that stored chemical weapons. The chemical weapons originally stored at the depot consisted of various live munitions and storage containers each holding 1 short ton (2,000 lb; 910 kg) GB or VX nerve agents or HD blister agent. All munitions had been safely destroyed by 2011 and base closure operations were still ongoing as of 2022.
