. Dr. James L. Liverman - -6- Augwt 17, 1977 3. During the next three years a study of resuspension of plutonium from soils in circumstances typical of those that will occur when the islands are reinhabited should be conducted. It is emphasized that this should not be a study of resuspension associated with cleanup activity per se. Information applicable to the Enewetak people will be invaluable in improving estimates of radiation dose to human beings returning to the islands and will assist in reaching decisions about future use of specific islands. 4. The EPA regards the crater disposal method as temporary storage. Under this view, maintenance of the concrete structure may be required. The Defense Nuclear Agency r,egardsthis method as permanent disposal which would imply no maintenance. This could lead to uncertainties of responsibility for future activities at the crater site. 5. A programmatic effort must be initiated to communicate to the Enewetak people the nature of the risks to which they will be exposed. The potential risks associated with living and visiting the various islands -t be made comprehensible to the people from their perspective to Insure their understanding the need for restricted access to Runit, etc. D. Concern for incomplete cleanup The reviewers were concerned that the cleanup program, as defined in the EIS, could be terminated before completion if the funds and other resources appropriated for the effort proved to be insufficient due to underestimates of the magnitude of the amount of soil that has to be removed. -
