All members and consultants worked either directly for sever EC or for an AEC laboratory, and most had been associated with t cEC efforts at Bikini Atoll. Liaison representatives of DNA, EPA, and 50 attended the Task Group meetings. The AEC Task Group’s findings were compiled in a “‘Report by the AEC Task Group on Recommendations for Cleanup and Rehabilitation of Enewetak Atoll,” which was circulated in draft form for comment in February 1974 and, after revisions, again in April 1974. There was lively debate, even among the AECstaff, over aspects of the report. Typical points at issue were: the appropriate contamination threshold for removal of soil from Runit and Boken; the scientific or technical basis for making a judgment that plutonium levels in the soil on Runit and Boken were high enough to justify removal of large amounts ofsoil; and the limited (3 weeks versus an annual program) air sampling data which indicated that airborne plutonium levels at Runit were quite low, comparable to some ievels in the United States.56 Dr. William Ogle, an eminentscientist long associated with the nuclear test program, was consulted by DNA on the Task Group Report. He questioned the recommendation thatthe dri-Enewetak be keptoff Enjebi until subsequent AEC measurements and analysis indicated that they could return to that island. His concern was based on the belief that the U.S. would not be in control indefinitely. He recommended that cleanup actions be taken which would allow the dri-Enewetak free use of theatoll in the future. Regarding Runit, he felt there was every reason to suspect that the problem was caused by small particles of plutonium. He | | | questioned the need for the dri-Enewetakto stay off Runit.*’ He realized that the AEC recommendations assumed there was a genuine hazard, but he felt that the information available did not fully support that assumption. He felt that Runit should be cleaned as well as possible and turned over to the people.>8 DNAbelieved that the recommendedcleanup standards (in terms of residual radiation) were too low (thatis, too conservative), that cleanup to these levels was not necessary, and that the funds likely to be made available for cleanup would not permit reducing residual radiation to these levels. In commenting on the April 1974 draft, one AEC office expressed the belief that the plutonium cleanup could be generally characterized as “reduction of plutonium contamination accessibility’’ and recommended that no numerical guides be published for residual plutonium levels in soil except those essential for guidance of a group of experts in the field to Eo
