Warren D. Johnson . -3- DEIS, even if one assumed that 79,000 cubic yards of Atoll soil containing an average of 1 nCi/gm of Pu239 were dumped into the ocean, it would represent only about 75 Ci for this one time action. This is far below ths.ypper disposal limit of 1010 ci/year for alpha wastes rt ee ee ot (based onPut? ) in Gov/1688. Without necessarily advocating ocean dumping, we note that itis considered by some to be the best solution to this problem and one of the least costly. Indeed, the ocean water already has a certain access to the plutonium in Enewetak Atoll and disposal in the deep ocean would only represent removal of the plutonium to a safer marine location which, because of its remoteness, would minimize the chance of human exposure. We therefore recommend that the pertinent sections on the DEIS be rewritten to leave the ocean dumping option open. Furthermore, we believe that return of this debris to the United States for burial would be | unacceptable and that burial on an island in a concrete-capped crater would require periodic followup that for practical purposes would last forever. Specific comments related to ocean dumping and encryptment are included in the enclosed Staff Comments. In the discussion of the “Impact of-Blasting During Cleanup" (Section 8.16) it is not clear whether these blasting operations will open new channels that would pass completely through the reef from lagoon to ocean. If this is in fact planned, we would object in principle and would need to see much more information on the expected impact of new openings in the reef on the ecology of the Atoll. As a matter of policy beyond the scope of this Statement, we recommend that the last sentence (lines 18-20) on page 5-35 of the fourth recommended Study be deleted, since it is not germane for any environmental statement to address detailed responsibilities of other agencies which = have not been formally agreed upon. There appears to be some misunderstanding regarding Storage on Runit. sae nee mms a2 anim had (Sections 5.5.2.5, page 5-48). As presented in the DEIS, it is indicated that as an intermediate step, contaminated soil will be stored on Runit pending a study and recommendation by AEC as to its ultimate disposal. AEC is not committed to provide any additional recommendation on the ultimate disposal of the contaminated soil. The disposal of debris is a DNA responsibility. The only open question is whether or not it may be feasible to reduce to some degree the amount of contaminated material wr
