448 RADIOLOGICAL CLEANUP OF ENEWETAK ATOLL However, the CJTG took the morepositive position that it was possible to clean up Lujor to under 80 pCi/g and the Fig-Quince area on Runi without extending the project.!!6 The CJTG proposal was modified by Field Command to consider these alternatives: a. Clean Runit to reduce transuranic contamination to the lowest leve| reasonably achievable within constraints of crater capacity and time and do nothing on Lujor. b. Clean Lujor to meet the 80 pCi/g criteria (encapsulating the soil), while accomplishing as rnuch excision on Runit as time and resources permit (encapsulating the Runitsoil). c. Clean Lujor to meet the 80 pCi/g criteria without encapsulating all of the Lujor soil, and concurrently excise and encapsulate Runitsoil as time and resources permit. Other considerations impacted on any expedited cleanup of either Lujor or Runit. These included soil removal requirements remaining at Boken (Irene), Enjebi, and the Aomon crypt; soil transport capability; status of crater fill; cement on hand; containment rate; and projection of crater domeheight. After careful deliberation of the Field Commandand JTG inputs, COL Peters (Director of Enewetak Operations) briefed the Director, DNA on the recommended options on 8 March 1979. Alternative a, clean Runit only, could be completed in the time available, would maximizecrater fill, and could be initiated without any channel clearance operations and without any need to consider boat transportation capabilities. However, there would be no guarantee that the island status would change, excavation to depths of 6 feet might be required, and the EIS requirement for Lujor would not besatisfied. Alternative b allowed containment of the Aomon, Enjebi, Boken and Lujor soil within the time and crater volume available, and it would change the status of Lujor to the benefit of the people and in accord with the EIS. However, it would place great demands on equipmentalready overtaxed, require channelclearance and additional IMPing, place excavation and transport operations under severe time constraints, and require additional bulk-haul boat configuration to get the job done in time. Alternative c had all of the favorable aspects of alternative b, plus it would permit intensive effort on both Runit and Lujor. It was less time constrained since the soil from Lujor would not necessarily be encapsulated. It still would have the problems associated with access to Lujor, trafficability, bulk-haul boats, and overall efficiency. Since the cleanup of Runit was of less benefit to the people than the cleanup of Lujor insofar as the ultimate usage was concerned, andsince either alternative could be accomplished in time to allow the crater to be capped by 15 September 1979, the Director, DNA decided to implement alternative b, with a modification. It was modified to regulate the input of
