Data Supporting the Screening Risk Assessment for the Pueblo Depot ActivityChemical Demilitarization Facility

摘要

The Pueblo Depot Activity Chemical Demilitarization Facility is located in PuebloCounty, Colorado, about 100 miles southeast of Denver and 14 miles east of Pueblo; the Arkansas River is approximately one mile south of the activity. The facility encompasses 22,654 acres and is situated on flat to gently sloped prairie. The surrounding lands are mostly undeveloped ranchlands used for grazing, with some light commercial and residential zoned areas to the south. The Pueblo Depot Activity was established by the Ordnance Corps in 1942 as Pueblo Army Depot with the missions of storage and supply of ammunition and general supplies during World War II. After World War II the depot received the additional missions of rebuilding and maintaining artillery fire control and optical materials; reconditioning transport and combat vehicles; ammunition supply, renovation, and demilitarization; chemical and conventional munitions storage; and maintenance of Sergeant, Pershing, and Nike missiles. The depot is one of eight sites that stores lethal unitary agents in the United States. The missile maintenance mission continued until 1974 when realignment transferred most of those activities to Letterkenny Army Depot in Pennsylvania. At that time, the depot was redesignated as Pueblo Depot Activity; responsibility for the activity was reassigned to Tooele Army Depot in Utah. The activity was recommended for realignment by the Defense Secretary's Commission on Base Realignment and Closure in its December 1988 report.
