At the invitati~n of Roger Ray, NVOO; Bill Forstcr, l~ll~~; _ Plarshall Islands Works hop,’ J-uric 27-29, 1977. I agrcc~ to submit my perceptions of the p~og ram in writing and ‘nqve restricted t’nese to four ma -i] areas. I identified thz followinq major areas of concern for attention by AES : 1) The lac~< of a and priorities . It is suggested that t!)e appointinerl~ of a scientific’ director for program management supported by a small steering committee is a priority requirement. 2) The rationale - for the Enewetak soil. cleanup ancl disposal operation i.s based been validated by empirical clata.

At the invitation of Roger Ray, NVOO; 13ill Fors’ceu, El IX; SI1OP at Lawrence Lj,vern’,ore Laboratory to take part in the research discussions. One ti]e first clay and park of ‘khe second each principal inves’ciqator presented an abstract. of ;Iis sttldy. ..-— segments of the overall program. It is pertinent to note t!lat this was the first time that tives f~oi~]AES, BER, and OES; NVOO; SAN; ancl principal invcs’ci- [Iawaii, Eowling Green State University had met. Since 1 was the only technical person p’resent wilo r,]asnot –. closely associated with the program, it was agreed by Bill !3urr, Bill F’orster, and Roger Ray that my ~,~Trittenperceptions of this workshop ~~ould he useful. 1 agreed to do this, but it should be borne j.n mind that 1 may have missed some of the finer p~i.nts in the technical and political discussions. In no way was I acting as a rapporteur for the workshop. While many project details were presented, I u7ill restrict-. my comments to four major areas” that I feel need ERDA senior mdnaqement attentjon. It was apparent that there was an ovcral.1 lack of direction in this prograin with the result that AES has a number of projects that do not necessarily share the same philosophy or ob]ecti.res. 17rom the Cliscussions the problem appears to exist ~liairllyat with DER. ‘Ihe issues and pro:~l-am Objcckl.vcs are not clear

The one project that ]:eceived tile most attention from tl-,e worksholo vjas the proposecl cleanup. of the Znewetak LzcjoorI Iclzncs . Initially, concern pjas expressed regarcliilg the plZICCY~i?ll 01 contaminated materials ancl soil on Runit. In part.j.cular the _ rationale for using CaCtUS crater for the contaminated concrete slurry was not o’bvious . This particular operation appearec: ‘co have many C?isadvantages in that it does ]lot remove the matc~ial from environmental int~raction since there are data that indicate ocean water connections do exist ar,d that erosion, etc. , will ultimately result in tile material being returned to the uncontrolled situation. As a repository for relatj.vely short–1.i~’ed radioactive materials this concept could be useful, but the consensus of the m.~etin(j Vlas that the crater was not a.n acceptable solution for plutonium contamindtccl h:astcs. The discussion then moved Lo alternatives . The most obvious one cliscussed was ocean disposal. outsiclc the lagoon. It was reporteii thut this was not acceptable to l;.l>.~~.

Adclitionally, the guidelines proposed for I.evel_s of plutonium in soil appeared to conflict with recently proposed federal guidel.i.nes and the basis for a double standarcl was not rnaile clear.

While it is appreciated that the DOD operation at.
