283 Soil Clean? Planning visit to the atoll, decided 978 when the Director, DNA,d during his ashoul be conducted as quickly as possible. January | that a pilot avrpose was to verify that soil cleanup actually could be The basic in that is, that surface contamination could be measured, that ed up secomp line xcision could be delineated, that a layer could be scrap d be ion woul an aes OF and that the resulting surface contaminat and rem reduced. [mportant subsidiary purposes were to determine significa equipment and procedures and to develop planning factors of ypuma manpower for each step ofthe process. On 3 February 1978, the eGrecommended Boken as the site for conducting the project. [t was cr of the four islands specified in the EIS for soil cleanup. Runit still was noite surveyed, and the in situ survey of Lujor had shown no concentrations above 160 pCi/g, well below the 400 pCi/g guideline for mandatory cleanup. The other island considered by the CJTG, Aomon, survey Jid not require any mandatory soil cleanup according to the latest jata.¢! . . . . . Despite these considerations, Field Command disapproved the selection of Boken because of its distance from Lojwa (Ursula) and Runit. After dixcussions with LTC Briggs, Field Commandselected Aomon to be the vite for the project in order to reduce the boat transport time between the worksite, the Runit soil stockpile, and the Lojwa Base Camp, and because the work site could be reached by truck from Lojwa. Director, DNA approved Field Command’s choice. COL Treat identified some 2 dozen sol cleanup activities for time-motion documentation to be used in pinning how best to accomplish contaminated soil removal.62 It took about 3 weeks to develop and coordinate a plan whichsatisfied all of these requirements.o3 Work on the project began on March 1978, the day after the plan was published. The pilot soil removal project used soil cleanup procedures which had been started on Enjebi in July 1977. The basic steps, after completion of the DOE-ERSP surveys described in Chapter 4, were: a. Identify the site and scope of work. = & coe _ Implement radiation safety and control procedures. . Survey and stake the boundaries of the excision areas. . Remove excess brush. . Excise the area and windrow excised soil. Resurvey excised area using the in situ van (IMP) and/or soil samples. y. Repeat steps e and f until contamination has been reduced to desired level, h. Transport soil from windrowsto beach stockpiles. |. Transport soil from beach stockpiles to stockpiles on Runit. These steps are described in some detail in the following sections. “Eee A
