July 1929 Camp McClellan was redesignated as Fort McClellan (FTMC) and continues to serve as a training area to the present day.

October 1940 The government acquired another 22,168 acres due west of FTMC. This tract of land was named Pelham Range in honor of Major John Pelham. In 1941, 4,160 acres were leased to the Federal Government by the Alabama State Legislature to provide an access corridor from the main post to Talladega National Park. This provided another 100,000 acres of woodland accessible for training.

May 1947 The fort ceased operations and was placed on inactive status until 1951.

1951 - 1973 Potential chemical materiel that may exist is due primarily to training exercises conducted by the U.S. Army Chemical Center and School.

4 January 1951 The Army reactivated FTMC on an unlimited basis for operation of the Chemical Corps School and as a replacement center for the Chemical Corps. The Chemical Corps School offered advanced training in all phases of chemical, biological, and radiological warfare to students from all branches of the military service.

1966 The mission of the installation was changed and the fort was renamed U.S. Army School/Training Center and Fort McClellan.

1977 An assessment of FTMC was performed; a few fenced burial grounds and training areas were suspected of containing both radiological and chemical contamination despite field decontamination, therefore warranting further investigation. The report also concluded that no contamination had migrated off-post.

May 1983 U.S. Army Environmental Hygiene Agency report on groundwater quality at FTMC concluded groundwater and soil contamination could still be present at FTMC.

January 1984 A reassessment of the original records identified several areas as potentially contaminated with chemical warfare agents (CWA). Most of these training areas were considered clean and available for surface activities.

December 1990 An enhanced preliminary assessment identified 67 potential sites, 17 of which had the possibility for CWAs and/or agent breakdown product contamination.

1992 - 1993 A site investigation (SI) studied 17 sites. Eleven of these were screened for CWAs and then analyzed for agent breakdown products; none were found. Nine sites with possible chemical agent contamination, along with three old landfills, were identified for further study during the current Remedial Investigation/Feasibility Study (RI/FS).

April 1994 Field work for a remedial investigation/feasibility study (RI/FS) with support from the installation and other organizations began.

July 1995 Field work was completed.

FTMC consists of three main bodies of government-owned and leased land (45,715 acres) in the foothills of the Appalachian Mountains in northeastern Alabama. No significant industrial or manufacturing operations occurred at FTMC. The implementation of chemical education and training programs led to the establishment of a number of training ranges both on the Main Post and on Pelham Range to supplement classroom training facilities. Individual ranges were used at different times for varying periods during the residence of the Chemical School. Historical data indicates CWM and conventional ordnance have been and continue to be used extensively at the Fort. Interviews revealed OE presence in Parcel A (Lagarde Park) and in T alladega National Forest.

CWM sites: Water Hole, Range I, Building 3183, Range K, DEI, Area T-24A, Range J, Area T-38, Area T-6, Area T-5, Range L, FTMCN-011, and T-31
