Umatilla Chemical Depot Army Base was an important chemical depot during World War II and one of the nine Army installations in the USA that stored chemical weapons. Nowadays, the setting of the base area resembles a series of camouflaged bunkers that can be seen from the outside for the driver that pays attention to those bumps alongside the highway.

 The disposal of all the ammunition and weapons stored at Umatilla Chemical Depot Army Base was safely concluded in 2011 and the base operation closure is expected to be completed before 2015 is over. Chemical weapons stored at this facility included different types of ammunitions and ton containers with either HD (sulfur mustard) blister agent, VX or GV nerve agents, which were destroyed with the aid of high-temperature incineration technology. This technology has proven to be successful and totally safe throughout the past 20 years, after the Army has discarded over 80% of the total chemical weapons in the country.

History: The Umatilla Chemical Depot Army Base was established in 1941 with the mission to store and maintain generic military items, including gears, blankets, and average ammunition. It was not until 1962 when this facility was turned into full-time chemical weapons deposit, to support the armed forces in Cold War times. Chemical weapons included sarin, mustard gas (sulfur mustard) and several other nerve agents. This large military base was operated by the U.S. Army Chemical and Biological Defense Command and curiously only stored 12% of all U.S. Weapons of Mass Destruction (WMD) stockpile in the nation.

Umatilla Chemical Depot Army Base was reorganized throughout the early 1990s delivering only standard ammunition and supplies to other military bases. Eventually, this facility began to get ready for closure after a United Nations resolution banned all storage and use of blister and nerve agents in 1993. Completion of chemical stockpile incineration occurred in October 2011 and nowadays the closure of this facility is imminent.

Due to its isolated location in Oregon, the 19,728 acres of Umatilla Chemical Depot Army Base are home to rare species of flora and flora, which are now a tourist attraction in the state.
