122 | RADIOLOGICAL CLEANUP OF ENEWETAK ATOLL | F whether the task would be accomplished by DOD aspartoftheclean, project or by TTPIas part of the rehabilitation program. The Master Inde was revised periodically, based on resurveys and planning changes, The most productive resurvey effort was that conducted in Septembe, 1976 during the visit to the atoll by the Enewetak Planning Council after the signing ceremonies. It had two objectives: (1) to comply with the ‘ direction of Congress that practical measures be taken to Teduce nonradiological cleanup costs; and (2) to refine nonradiological cleanup plans. Before the main party arrived, engineers from Field Command and H&N made a detailed survey of each island. This survey revealed that some of the work identified in the first field survey in 1972 had been modified or eliminated by natural forces, such as the complete corrosion of metal. In a significant modification of previous plans, Lieutenant Daviq Gebert, USN, of Field Command, and Mr. Charles P. Nelson, of H&an (for TTPI), arranged an exchange of TTPI workin the northernislandsfor DOD workin the southernislands. Before this agreement, DOD hadthe responsibility for cleanup of radiological debris and hazardous nonradiological debris, and TTPI had the responsibility for cleanup of nonhazardous, nonradiological debris. Since both types of nonradiologica| debris were present on both the northern islands and the southernislands, work crews from DOD and TTPI would be engaged in parallel efforts on virtually every island. This had an added disadvantage in the north,forit meant that TTPI crews would have to be integrated into the radiological safety program. By exchanging jobstotalling an equal number of man- hours, DOD took overall of TTPI’s responsibilities for nonhazardous, nonradiological debris in the north, and TTPI took over an equal amount of DOD’s responsibilities for hazardous, nonradiological debris in the south. Thus, TTPI’s site restoration work was restricted to the residence islands, and all cleanup and restoration work on the contaminated northern islands would be accomplished by DOD. This exchange also eliminated such inefficiencies as having DOD remove hazardous pipe stubs from a nonhazardous concrete slab before TTPI removed the whole slab. Upon their arrival, the Planning Council reviewed the survey and suggested additional work reductions such as leaving asphalt runways in areas designated for tree planting and cutting holes in them to permit planting, and leaving flat concrete foundation slabs for use as copra drying locations. The Planning Council passed a resolution approving the resurvey results, and the Master Index was revised accordingly. This resurvey eliminated approximately 80,000 man-hours of work from the southern islands cleanup effort.274 The Planning Council also agreed to the following criteria for nonradiological cleanup of islands, according to use-categories defined in the March 1975 Master Plan:275 —_ eo ee ee ee
