7 ~ ations Soil Cleanup Oper FIGURE 7-38. AOMON CRYPT SITE RESTORATION. Extracted sheet pile was monitored by the FRST, and those sections requiring decontamination were cleaned on site by the USAE. A large portion of the sheet pile (85 percent) was declared reusable and was subsequently moved to Enewetak Campfor future shipment to Johnston Atoll. Unusable sheet pile was treated as debris and dumpedatsite Bravo. Upon completion of the excavation and restoration operation, DOEERSP again performed anin situ survey with the IMP. Additionally, they used a simplified drill mechanism to obtain a 5-foot depth sample from 26 locations over the backfilled area. These depth samples were homogenized, analyzed, and found to meet the required criteria. As on all other soil removal projects, the work site, beach soil and debris stockpile areas, as well as all routes taken bythe trucksin delivering the soil to the water craft were surveyed by the IMP. ~ 3 AOMON CRYPT TRANSPORTATION PROBLEMS The movementofall debris from the crypt to Runit was accomplished between 1 February 1979 and 23 May 1979 using 20-ton dumptrucks and LARC-LXs. All debris from the Aomon Crypt was treated as contaminated debris and entombed within the Cactus Crater Dome. ge
