496 RADIOLOGICAL CLEANUP OF ENEWETAK ATOLL yp and completed successfully with no adverse impact on the completion of the cleanup project. While analysis of the technical data obtained during the survey is ongoing, preliminary indications are that the datais of high quality and that the accomplishment of the EASI project has provided significant contributions to the understanding of cratering mechanics and effects. COMPLETION OF CLEANUP OPERATIONS On 5-8 February 1980, the final quarterly review was conducted with the dri-Enewetak municipal and planning councils, the Chief Secretary of the GMI, Field Command and TTPI representatives to assure that all remaining cleanup work wasidentified prior to departure of the Military Service elements.°4 The review found that all remaining work had been scheduled and was being accomplished well ahead of schedule. Army and Navy elements were reduced to the minimum essential to complete their remaining cleanup tasks. The watercraft which had been declared unserviceable by all concerned were disposed of by the USNE prior to their departure. The week of10 February 1980, four landing craft and three miscellaneous craft were sunk at dumpsite Alpha. Prior to their departure, the USAEpolicedall beaches and cleaned out the burn dump at Enewetak Camp. ; A trailer chassis was discovered on Ribewon (James) Island in early February 1980. The last LARC had been retrograded on the January sealift, and the island was unapproachable by landing craft. Two men were airlifted to the island by helicopter to burn the tires and cut the chassis into pieces which could belifted by helicopter. The residue was dumpedatsite Alpha by helicopter.°5 On 15 February 1980, H&N-PTD assumedresponsibility for POL and airfield operations from the Air Force teams. On 27 February 1980, the remaining military service cleanup forces, with the exception of those required to support rehabilitation and rollup operations, redeployed from Enewetak Atoll. In the 27 months since the Cleanup Phase began, they had accomplished the hazardous cleanup plus a considerable amount of workidentified as cosmetic cleanup. The cleanup had been accomplished 1-1/2 months earlier than anticipated in OPLAN 600-77, despite typhoons, organizationaldifficulties, logistics problems, and otherdelays. In accomplishing the cleanup of Enewetak Island, the JTG disposed of a total of 132,780 cubic yards of hazardous and obstructive debris.This total includes 22,000 cubic yards which were removed by a Scrap contractor and 49,340 cubic yards which were used as shoreline protection.
