Runit (Yvonne) Cleanup and Crater Containment 449 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 Lujor.!!7 Bythis restriction on dome fill with the easier-to-transport Runit soil, the Director, DNA hoped to ensure that ali Lujor soil would be encapsulated. On 13 March 1979, the CJTG received directions to proceed 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 15 April 1980, the end date set by DNA. Field Command engineers had suggested that the POD designbe 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 4 25-foot dome. !19 Upon receipt of the 13 March 1979 directions, the JTG proceeded to excise and encapsulate Runit soil at a rate which would sustain soil-cement operations while awaiting the delivery of soil from the other islands. Efforts were expanded to open a channel for boats into Lujor but the strong currents between Lujor and Aej continued to hamperthe successful marriage of the LCUs with the boat ramp. 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 containment rate, 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 Commandthat 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 CJTGwasdirected to halt, temporarily, the containment of Runit soil 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 on thefact thatall of the Lujor soil was less than the 160 pCi/g i_
