These principles were followed in the Bikini Atoll cleanup, the n.ost .pprooriate precedent for Enewetak. The Enewetak cleanup and rehabilitation recommendations, including the restrictions, are similar to those for Bikini. About the same order of conservatism was used in applying the standards. While there are no national or international criteria for plutonium cleanup, the staff recommendations are consistent with a recent, independent study performed by LASL entitled, "A Proposed Interim Standard for Plutonium in Soils, '' LA-5483-MS, dated January 1974. EPA plans to develop cleanup guides for plutonium contaminated land but these will not be availanple for some time. Plutonium contamination on the islands of Enewetak is confined principaily to well defined and relatively small areas. The exception is the contamination on YVONNE; about half of the 94 acres of this island is highly contaminated. There is a wide range of particle sizes, and the distribution in the soilis not uniform. The recommended criteria for cleanup of plutonium in the soil are intended for use throughout the islands of the Atoll. Specific recommendations for cleanup of YVONNE are also given. Decontamination of YVONNE is seen as an iterative process to be conducted bv a team of experts. There remains the difficult problem orf disposal of the contaminated soil which is a responsibility of DNA. However, by the time cleanup is started, a method for ~isposal may be available. If not, then the plutoniumdebris throughout the Atoll should be retained on YVONNE and the quarantine of that island continued unil contamination is removed. Further study is needea on possible removal of the plutonium contamination OREMeT oremante ete a pean SOTREToe MENG Reg wh CG a + ee ~ me2 f +¢ | teeta on ere ey t . 4 ' s 1 = wpe 7 i oe, , . . rine Lane. ae gene ’ . * . : ay , een ‘ag .
