The Umatilla Chemical Depot (UMCD) was one of nine Army installations in the United States that stored chem ical weapons. The chemical weapons originally stored at the depot consisted of various munitions and ton containers c ontaining GB or VX nerve agents or HD blister agent. Stockpil e disposal operations were successfully concluded in October 2 011 using high-temperature incineration technology. This tech nology has been used by the Army for more than two decades, sa fely at several sites to successfully dispose of more than 80 percent of the nation’s original chemical weapons.
The Army worked in partnership with Oregon state an d local government agencies, as well as federal agencies li ke the U.S. Environmental Protection Agency and the Centers for Disease Control and Prevention, to safeguard the local comm unity and protect the environment as we stored and disposed o f these chemical weapons. The Army safely stored approximat ely 12 percent of the nation's original chemical weapons a t the Umatilla Chemical Depot starting in 1962.

The UMCD opened in 1941. The depot's mission was to store and maintain a variety of military items, from blan kets to ammunition.

Fr om 1990 to 1994 the facility reorganized in preparation for eventual closure, shipping all conventional ammunition and s upplies to other installations.
