SITE DESCRIPTION
Site VAAP-05 consists of the western-most of the two magazine areas located in the eastern half of the installation. The site previously contained 100 igloo-type magazines for storage of final TNT product. Explosives are no longer stored at VOAAP.
A portion of this site was the 975.95 acres sold to Hamilton County and the City of Chattanooga for $7.5 million via negotiated sale under early transfer authority in September 2000. Supplemental investigations were conducted and contaminants were discovered in soil/sediment and groundwater. A removal action of contaminated soils within the conveyed property was completed in September 2001. The storage magazines were subsequently demolished by Hamilton County. Groundwater sampling continued until 2002 and the results indicated that no further action was required. The site has been removed from the TN Superfund list; the site was not part of the RCRA Order.
One small area (approximately 300 ft2) near the railcar loading area required explosives remediation. Removal was implemented to the degree feasible in 2001, but additional TNT contaminated soil remained in place below the building. Therefore, an additional removal action was completed in March 2004, which included razing of Building 908-4 and excavation and off-site disposal of impacted soils. Results of the confirmation sampling, conducted after the removal action, as presented in the CMS/ICM Report, indicated that the contamination had been removed. Upon regulatory approval of the removal action, this additional area will be RC.
