These activitica concern the surveys essential to the cleanup, rehabilitation, and resettlement of the atoll in coenection with the anncunced return of Eniwetek to the Truat Territory of the Pacific Islands (TTPI). In April 1947 the Unired Nations formally designated the former Japanese Pacific Mandates (Zaiwetak included) as Trust Territories to be administered by the United States. Upon written notification to the U.x., Eniwetok was designated a nuclesr testing site in December 1947, with the first test series there, SANDSTONE, being conducted in the apring of 1948. Prior te SANDSTONE, the Eniwatek people, about 136 in aumber, were mowed by the United States to Ujelang Atoll where they still reside, although their sumber has now increased to about 432. Additional test series vere conducted in the atoll during the years 1951 (GREERHOUSE), 1952 (IVY), 1954 (CASTLE), 1956 (REPWING), and 1958 (HARDTACK - PHASE 1). The last of 43 teste was in July 1958. All teeta have been listed publicly. Geographic location of the atell is shown in Figure 1. Ite remoteness suggests inherent costly operations to accomplish the necessary surveys and subsequent clesnup. Figure 2 identifies the islands of the atell and general location of the nuclear tests couducted. On April 18, 1972, High Commissioner Johneton and Ambassador Willians jointly announced the intention of the United States te reture Eniwetok Atoll te the TIFI subject to retention of seme minor residual rights. Subsequently, the Department of Iaterfor (DOI), Department of befense (DOD), and AEC determined thet a couprehensive and coordiaated program to survey and clean up Eniwetok Atoll] must be undertaken to make Enivetok habitable. The program was divided into three phases: (1) Pre-cleanup Radiological and Engineering Surwey, (2) Cleanup, and (3) Rehabilitation repository D8é thstery Division BEST COPY AVAILABLE CoLLecTion RG326,lommy Mcrw Jose 1322 — ° BOXNo. —2 FOLOER © > ay reh or"\ }
