aN 298 RADIOLOGICAL CLEANUP OF ENEWETAK ATOLL from the time scheduled in the OPLAN for soil cleanup, COL Trea estimated that, unless the project were extended beyond its scheduleq . April 1980 completion date, only 12 months wouldbe available to exciga and transport soil from the northern islands, leaving another 2-1/2 Months to complete Runit soil cleanup and | month to finish closing the Concrete cap. His study predicted that only 60,000 to 67,500 cubic yards of soil could be moved by boat in that 12 months. The Director, DNA was determined to complete the project on time unless it proved manifestly impossible to do so. He believed his two overriding commitments were: (I) to achieve satisfactory radiological cleanup results for the dri-Enewetak; and (2) to complete the project on time and within the funds appropriated from the taxpayers by the Congress. While thefirst was paramount, VADM Monroe felt the seconq also was of critical importance, and he still believed both could be achieved. On-time completion was of great importance because of the significant drain on the Services’ manpower, funds, equipment, and other resources. VADM Monroe remained confident that COL Treat’s initiaj time and quantity factors would improve with experience, and that other efficiencies could be found. Boat transportation was the principal constraining resource. There was enough engineer manpower and equipment to excise and contain the 150,000 to 180,000 cubic yards of soil COL Treat estimated it would take to reduce all islands, including Runit, to below 40 pCi/g. The elongated configuration of the Cactus Crater container design would provide sufficient volume and the MILCON fundsfor crater containment appeared to be adequate to contain the currently estimated amounts of contaminatedsoil. The crux of the boat transportation problem was Enjebi. Field Commandestimated that 57,900 cubic yards would have to be removed from Enjebi to bring it below 40 pCi/g. This would use almost all of the transport capability for a year. Alternatively, in the same year, 63,700 cubic yards of soil could be removed from seven other northern islands (excluding Enjebi and Runit) to bring all seven to below 40 pCi/g. Runit could be cleaned in either case since no boat assets were required. According to COL Treat’s initial rough estimates, two obvious alternatives were: (1) clean Enjebi to residential levels and clean Runit, or (2) clean the other seven islands and Runit.’?3 However, two old Runit issues, which COL Treat had been studying and reviewing with the ERSP manager, were reopenedin thebriefing. 74.75 The ERSP characterization of Runit, requested in not, for a number of reasons (previously discussed), the time of the Il April 1978 meeting with Director, conference, it was proposed again that, since Runit October 1977, had been completed at DNA.
