delete these islands from the effort. PACE was then active and any earth moving or other land modifications conducted by them would negate any survey results before they could even be reported. However, while the survey was in progress, FACE was enjoined by court action to cease all activities on the Atcll. At that time it was determined to be prudent to include these islands in the precleanup survey efforts. Thus, the soils survey was extended to include only the UNDICTUREED areas of SALLY, RUBY and SALLY'S CHILD. The following information was considered necessary to the cleanup estimate effort: 1. Stratify the islands into three arbitrary groups. 2. Define to a depth of 180 cm (6 ft.) contamination over very large areas. 3. Determine only large volumes of contaminated soils. 4, Limit study to only those areas not disturbed by Project PACE. Phase IV Island. YVONNE (RUNIT) was the only island classified in Phase IV, “severely contaminated". YVONNE is at the top of the list in the fallout insult ranking, the site of eight SGZ's, with a total H+l hour insult of 62,849 R/h. location on the Atoll. Historically, the island is the most disturbed testing Records searches produce many conflicting reports of radioactive materials disposed of on or near the island. siderable construction and reconstruction activity.

The island is the known site of tons of activated or contami- nated scrap and undetermined quantities of plutonium-contaminated soil. Every recent survey effort from July 1971 through the several cursory surveys conducted late in 1972 end early in 1973 confirms the indication that the northern nolf of the island is 9 BSSEScous conglomeration of radioactive contaminated debris buried to great depth (up to 10 ft.) at known and unknown
