Deseret Chemical Depot

[3][4] 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.

[11] At 9:24 AM UTC-07, September 5, 2002,[12] officials at the depot triggered the Terrorist Alert Warning System in response to an unidentified intruder being spotted just inside the 7-foot barbed wire fencing at Cemetery Ridge, a mile north of the incinerator[13][14] It was the first time that the alarm, which alerts employees to possible terror threats, had been sounded since new security measures were instituted after 9/11.

Army officials later stated that the black-clad trespasser, sighted by four different soldiers during two different patrols,[13][12] immediately ran off towards Ophir Creek, escaping capture, according to the depot Commander, Col. Peter C.

[18] When asked why the intruder could have escaped capture, Wade Mathews of the Tooele County emergency management noted, "There's a lot of foliage out there."

[13] Col. Cooper emphasized that the intruder was not in the area where chemical weapons were stored, but "unsettling questions remain" about his intentions,[19] as there was no evidence of anything being stolen or that terrorism was in fact involved.

[20] Deseret Chemical Depot officially closed July 11, 2013; however, it is unclear whether or not the hundreds of government employees and contractors employed at the time have transferred to other bases.
