Deseret Chemical Depot

The Deseret Chemical Depot (ⁱ/dɛz.əˈrɛt./) was a U.S. Army chemical weapon storage area located in Utah, 60 miles (100 km) southwest of Salt Lake City. It is related to the Tooele Chemical Agent Disposal Facility.

The area was used to store chemical weapons between 1942 and 2012 with weapons destruction beginning in August 1996 at the Depot which held, at that time, 45% of the total U.S. stockpile. After initial demilitarization operations concerning the Weteye bomb concluded a total of 888 of those bombs were left in storage at Rocky Mountain Arsenal. After rounds of protests from residents of Utah, the state's governor, and legal action the munitions were transferred to what was then known as Tooele Army Depot South Area. The first transfer of Weteyes took place in August 1981 and the moves continued for three weeks. After these transfers the South Area became known as Deseret Chemical Depot.

As of January 2007^[update], 7,593 tons (6,888 metric tons) of chemical weapons have been destroyed using incineration. All GB (sarin) was destroyed by March 2002 and all VX by June 2005. In 2006, the facility was changed-over to handle destruction of mustard gas in ton-sized containers. By March 15, 2009, 3,216 ton containers and 54,453 projectiles of mustard gas had been destroyed (51.5% of Deseret's mustard agent stockpile). The last explosively configured mustard gas munition was reported destroyed in May 2010. All Tabun (GA) was destroyed by November 10, 2011. Disposal of land mines containing mustard gas as well as a small stockpile of Lewisite has not been completed. All disposal operations concluded January 21, 2012.
