126 © SP RADIOLOGICAL CLEANUP OF ENEWETAK ATOLL The conferees prepared a new schedule for developing an OPLAN and for mobilizing personnel and equipmentbased on a |5 June 1977 D-Day. They also developed plans for support of the rehabilitation program. Plansfor the early return of 50 dri-Enewetak to Japtan in March 1977 were completed, as well as plans for employing someofthe dri-Enewetak in the cleanup and rehabilitation work. Logistics policy and plans for supportof the activities at Enewetak were also developed.287 BG Lacy’s team next met in Saipan with the Acting High Commissioner of the TTPI, Mr. Coleman, and the dri-Enewetak legal counsel, Mr. Mitchell, on 20 November [976 to coordinate plansfor the early return ang for interface of the cleanup and rehabilitation efforts. The Field Commanq team then conferred with Hawaiian area officials on 22-23 November 1976 on preparations for the cleanup project, including establishment of branch exchange at Enewetak and a forthcoming survey by a Navy team.288 This Navy survey team, assisted by Field Command personnel, conducted a thoroughinvestigation of Enewetak Atoll waters and beaches from 30 Novemberthrough 15 December 1976. They produceda definitive report of harbor clearance requirements, beach access andtrafficability, and personnel and equipment requirements.289 The report was incorporated in the Field Command OPLANwith only minor changes.In December1976, a team from the Pacific Air Forces Surgeon’s Office also conducted a survey at Enewetak Atoll in preparation for establishing a Medical Clinic at Enewetak Camp and a Medical Aid Station at Lojwa Camp.290 CRATER CONTAINMENTDESIGN: 1975 - 1977 On 29 November 1976, POD completed theinitial ‘‘Design Analysis for Crater Containment of Contaminated Material at Enewetak.”’ It concluded that use of Lacrosse Crater would be unduly expensive and provided procedures for use of Cactus Crater, as the preliminary DEIS had proposed. At Field Command’s request, the design analysis provided for a capacity of up to 200,000 cubic yards of soil, the worst case anticipated,29!.292 with the capability of containing even larger quantitiesif necessary. POD recommendedthat the tremie method of placing soil- cementslurry be used below the waterlevel only and that placement above the water level be accomplished by windrowing the dry soil and cement, then spraying it with waterto initiate the cement’s bonding action.293 The PODdesign called for containing contaminated debris in the contaminated slurry mix and using dikes to contain slurry and debris placed after soil cement operations had begun.294 Further details on crater containment design and construction are in Chapter 8. —— a
