384 RADIOLOGICAL CLEANUP OF ENEWETAK ATOLL slipped due to equipment breakdowns and diversions of resources to increased soil removal efforts on the northern islands. However, work did progress smoothly and, in May 1979, the PACE area wasrestored to the satisfaction of the people, with natural drainage toward the lagoon.49 4 total of 141,000 cubic yards of soil had been relocated. Figures 7-45 and 746 show the PACE test site before and after the restoration operation. During the restoration operation, a numberof problems surfaced. The most urgent one was locating enough soil to fill the PACE test area.50 Whenthe soil had been removedoriginally, it had been stockpiled north and east of the test site. The northern stockpile was subject to tidal and wave action, and muchofit was washed away. In addition, someofthesoij had been usedto fill the salt pond and wasto beleft there. Consequently, there was a shortageofsoil to fill the test bed. This problem was resolved by using soil from a ridge which extended from the PACE crater toward the Kickapoo GZlocation on the ocean side of Aomon andsoil washed up along the beach to the west ofthecrater. The second problem concernedtheradiological condition ofthefill soil, It was found through a DOE-ERSPinvestigation that the PACE testsite was uncontaminated. It was necessarytofill the craters with soil having a radiological characterization equal to or less than the criteria for the proposedisland usage—residential (40 pCi/g). Upon furtherDQE-ERSP investigation, the soil (original stockpiles and proposed borrow sites) was found to be suitable for the purpose. Thethird problem concerned the northern portion of the test area. This area had to be restored early in the project to provide a haul road from the Kickapoo GZlocation to the lagoon beach where LCM-8 and LCU craft were loaded for transport of contaminated soil to Runit. The PACE site restoration in this section was given a high priority and was rapidly completed, allowing the contaminated soil cleanup work to proceed on schedule. FIELD COMMAND’S DRAFT DOSE ESTIMATE STUDY While soil cleanup was progressing, Dr. Bramlitt was developing the study requested by the Director, DNA during the 4 May 1978 conference to determine dose from all radionuclides (both transuranics and fission products) as they mightaffect the EIS Case 3 lifestyle. The draft sudy was completed on 6 July 1978. It indicated that the Case 3 lifestyle might lead to dose rates in excess of guidelines which had been prescribed by the Atomic Energy Commission (AEC); however, the reason hadlittle to do with transuranic elements. Dose from transuranic elements was found to be well within guidelines proposed by the EnvironmentProtection Agency vO —_— —
