The primary chemical weapon storage facilities in the U.S. are Umatilla Chemical Depot in Oregon, Pueblo Chemical Depot in Colorado, Blue Grass Army Depot in Kentucky, Anniston Chemical Activity in Alabama, Pine Bluff Chemical Activity in Arkansas and Deseret Chemical Depot in Utah.[27] The largest of these facilities is Deseret. Other non-stockpile agents (usually test kits) or old buried munitions are occasionally found and are sometimes destroyed in place.
