The 1999 113.047 acres of nitrate (Buildings Record of Decision (ROD) for Operable Unit Three land N~1, N-2, N~3, N-5, identified the selected remedy as excavation of lead- contaminated soil at the General Storage Area/Salvage N~7, N-9, N~11, Yard to levels below the RAO for lead (400 I-Ig/g), N~13, N~15, and transportation of contaminated soil to an off~site disposal N~17)(S) facility, and implementation of institutional controls to 1946~ 1948 prevent residential use. Ammonium nitrate fertilizer (S) Preparations to excavate the lead-contaminated soils within Production periods, the Nitrate Area were initiated in May 2000. Prior to Laboratory possibly 1942~1945 excavation activities, composite delineation samples were chemicals and and 1950~ 1957 collected at a depth of 6 inches to 1 foot. The analytical explosive waste results of all composite samples were below RAOs for lead (400 I-Ig/g). As prior analytical detections of lead- (Buildings X-1, X~3, contaminated soils could not be confirmed or replicated, no and X-4)(S) 1968.1973 excavation activities at the Nitrate Area were completed. Details of sampling locations and analytical results of the Explosive composite sampling are presented in the Closeout Report compounds and for the Soil Investigation and Excavation of OU3, 2001. waste from mine test facility Based on the results of the composite sampling in 2001, (Building N-2) (S) 1965~ 1990 concentrations of lead in soil at the Nitrate Area were not confirmed above NDEQ guidance concentrations. As a PCB Transformers result, the selected remedy for lead in soil at the Nitrate Area has been achieved. and automotive batteries containing Beginning in December 2003, decontamination by thermal lead (Buildings N~1 decomposition and demolition of several buildings in the and N~3 in Salvage Nitrate Area was performed for residual explosive Yard) (S) 1979 to present contaminants, including Buildings N-1, N-2, N-3, N-5, N-7, (associated with N-9, N-11, N-13, N-15, X-1, X-3, and X-4. On October 20, Solvents, paint, railcar refurbishing 2004, the contractor performing this work certified that the identified buildings had been decontaminated to a 5X level and silica sand for operations) and therefore the affected parcels of land could be sandblasting transferred for sale. (Building N~17 and Drum Areas to the For the work that is performed in accordance with IOCP North and South of 385-1, the 5X designation indicates that no significant Building N~17) (S) amounts (not enough to present an explosive safety hazard) of contamination remain. Several criteria must be met to achieve the 5X certification. Among these criteria are thermal decomposition of buildings at a sufficiently high temperature and a determination that explosive soil is not present. For the Nitrate Area sites, the criteria used to determine whether soil was considered explosive was a determination that the soil did not contain greater than 10% by weight of any secondary explosive or mixture of secondary explosives in soil samples.
