REPORT BY THE TASK GROUP ON RECOMMENDATIONS FOR CLEANUP AND REHABILITATION OF ENEWETAK ATOLL INTRODUCTION ° On September 7, 1972, the Atomic Energy Commission (AEC) agreed to provide radiological criteria for cleanup and rehabilitation of Enewetak Atoll to the Department of Defense (DOD) and to the Department of Interior (DOI). AEC also agreed to conduct a comprehensive radiological survey. The purpose of the survey was to gain a sufficient understanding of the total radiological environment of Enewetak Atoll to support judgment as to whether all or any part of the atoll can safely be reinhabited and, if so, to deseribe cleanup actions to be taken by DOD and any constraints. These tasks are identical to those performed for cleanup and rehabilitation of Bikini Atoll and that experience has greatly aided the development of recommendations for Enewetak, Radiological survey field operations were conducted between mid-October 1972 and mid-February 1973. Samples taken in the field have been analyzed and complete results of the survey have been published as a Nevada Operations Office document (NVO-140), Enewetak Radiological Survey, Vols. I, II, III. An abstract of NVO-140 is presented as Appendix I of this report, and the "Summary of Findings" chapter is reproduced here in Appendix II. In July 1973, a Task Group was established to review the survey findings and to prepare cleanup and rehabilitation recommendations for consideration by the Commission. Members of this Task Group are: Mr. T. McCraw (AEC/OS), Dr. We Nervik (LLL), Dr. D. Wilson (LLL), and Mr. W. Schroebel (AEC/DBER). Advisors and consultants to the Task Group have included Dr. E. Held (AEC/REG), Dr. R. Conard (BNL), Dr. H. Soule (AEC/WMT), Dr. N. Barr (AEC/DBER), Dr. R. Maxwell (AEC/DBER), Mr. L. J. Deal (AEC/OS), and Mr. R. Ray (AEC/NVO). Staff liaison representatives from DNA, EPA, and DOI attended Task Group meetings. -1- b
