6 consists of five sub-areas related to the former Penniman shell-loading plant. The Penniman shell-loading plant was an explosives manufacturing facility operated by the DuPont de Nemours Company during World War I on what is now CAX and adjacent properties. The five AOC 6 sub-areas were identified through aerial photographic analysis as follows: Ammonia settling pits – This area consists of earthen ammonia settling pits that were part of a former shell-loading area located on Cheatham Annex. Wastewater from an ammonia finishing building was discharged through these settling pits. TNT-graining house sump – These areas consists of a concrete-lined, open-top pit believed to be the sump pit for the trinitrotoluene (TNT) graining house in the former shell-loading area. Located near the dam at Penniman Lake. TNT catch box ruins – The catch box ruins area consists of an earthen, brick-lined depression located immediately adjacent to the TNT-graining house in the former shell-loading area. This area was used to separate TNT particles from wastewater. Located near the dam at Penniman Lake. Waste slag material – This area consists of waste metallic slag material that is located throughout the shell-loading area predominantly along the railroad tracks. 1918 drum storage – This area was used for the storage of 55-gallon drums when the shell-loading area was active. The site is currently a yard area around facility buildings. AOC 7 consists of several small surface debris disposal areas containing a few 55 gallon drums and cans. One of the areas of note is a pit approximately 30 feet by 20 feet and 8 feet deep that contained 40–50 10-gallon rusted cans with labeling containing the word “tetrachloroethene.” AOC 7 is located north of Building 14 and Site 8. AOC 8 is a very small area along the perimeter of the York River, buried debris (pipe, metal, and wood) can be seen cropping out from the edge of the slope and along the beach. Test pits conducted in 1999 indicate that the waste post-dates World War I and does not appear to be associated with DuPont Penniman facility waste disposal. AOC 9: Penniman Lake is 48-acre surface water body located in the southeastern portion of CAX that was created in 1943 when a portion of King Creek was dammed.
