ASTs with secondarycontainment are generally used to store petroleum products. Petroleum products are stored innumerous ASTs within the cantonment area and include newly constructed contractor-owned, contractor-operatedbulk and retail fuel facilities that provide fuel to all military units on FTC. Undergroundstorage tanks have been used to store gasoline, diesel, aircraft fuel, and other fuels. Threecommercial gas stations are operated on FTC, and each station contains three USTs (DECAM2004b).Petroleum-based products are stored in several ASTs and at the hazardous cargo loading area locatedat the south end of the runway at Butts Army Airfield. Petroleum-based products are used in the repairof malfunctioning targetry systems and military vehicles and for replacement of obsolete or malfunctioningtargetry systems such as lifters that contain hydraulic fluids (USAEC 2006b).The painting, repair, and maintenance of 47 aircraft and their supporting wheeled ground vehicles requirethe use of POLs and other hazardous materials. Aircraft maintenance hangars, one hot-refuelpoint, and one outdoor wash rack are used to perform standard vehicle maintenance (DPW 2004).Additionally, painting operations are conducted at a paint booth in one of the old hangars. Lead acidbatteries are used for all aircraft and their supporting wheeled vehicles.Contaminated and IRP SitesFTC is not listed on USEPA’s NPL, which designates high-priority cleanup sites under CERCLA,more commonly known as the Superfund Program.
