TAK ATOLL Runit (Yvonne) Cleanup and Crater Containment was possible to Runit soil to 1,000 cubic yards per week and not to exceed 12,000 cubic yards pending evaluation of the progress on Boken, Enjebi, Aomon and ea on Runit 3 modified by Lujor.!17 Bythis restriction on domefill with the easier-to-transport Runit soil, the Director, DNA hoped to ensure that all Lujor soil would be encapsulated. On 13 March 1979, the CJTG received directions to proceed . ‘e lowest level icity and time with concurrent cleanup of Lujor and Runit.!18 AS a practical matter, a limit had to be placed on the domesize to assure. that it was completed in time to permit capping and the demobilization by 1S April 1980, the end date set by DNA. Field Command engineers had suggested that the PODdesign be followed and that the dome be extended inland as necessary to contain the additional volume required for the worst-case estimate of cleaning both Lujor and Runit. However, as a result of discussions during the 8 March 1979 briefing, the Director, DNA decided that soil-cement and capping operations would be directed toward ting the soil), and resources sulating all of : Runit soil as ‘f either Lujor ling at Boken lity; status of jon of crater a 25-foot dome. !19 Upon receipt of the 13 March 1979 directions, the excise and encapsulate Runit soil at a rate which would operations while awaiting the delivery of soil from Efforts were expanded to open a channel for boats inputs, COL tor, DNA on clean Runit erations and 2s.

However, it appeared that the LCM-8s would be successful in getting into Lujor, but with an attendant decrease in soil removal capability. By 24 March, approximately 2,400 cubic yards of Runit (Fig-Quince) soil had been contained and, with the troops on Runit accelerating the containmentrate, the soil stockpile was almost depleted. The containment rate reached 4,220 cubic yards during that week, and soil was not arriving fast enough from Boken, Enjebi, Aomon and Lujor to sustain a stockpile. The rate of containment for Runit soil caused concern at Field Command that whatever dome volume might remain for contingencies would be used for Runit soil. The fission products survey was uncovering additional subsurface contamination on Boken and Enjebi which had not been considered in selection of a dome volume. The CJTG wasdirected to halt, temporarily, the containmentof Runitsoil after 5,720 cubic yards had been excised in less than 3 weeks. The CJTG then requested approval of a plan to maintain an effective containment rate, clean Lujor to agricultural levels, and make the most productive use of available resources to clean Runit. The plan provided for excising and containing Runit soil over 160 pCi/g at the rate necessary to sustain efficient soil-cement operations (3,000 to 5,000 cubic yards per week), while stockpiling the Lujor soil for subsequent containment or backfill of the Fig-Quince area as circumstances indicated. The suggestion was based onthefact that all of the Lujor soil was less than the 160 pCi/g
