g. The concept of phased operations presents the opportunity to make an initial gross survey of the islands to identify those with the 2 highest procasility for soil removal. 3 These data will greatly assist in 4 develoning werkéng estimates of soil to be removed. h. An ERDA aerial survey system will be fielded as early as possible (i.e., shipped in mid-June and operational shortly thereafter). 2 6 This aerial systen would proceed to survey the islands where soil removal 7 possibilities exist (see Tabs A and B to Apnendix 2 of Annex (C). 8 i. 9 The first van will be shipped approximately 1 July and become operational in mid-July, a second van, will be operational in August and 10 both will commence with the fine surveys. the August/September time lL frame, sufficient fine surveys can be completed to allow soil removal to 12 begin in the planned mid-November time frame. 13 By As noted in 3.b above, the initial soil samples for van calibrations will be sent to McClellan AFB for analysis. 14 The Radiochemistry Laboratory is expected to become operational on Enewetak in August. 3. 16 Athird van is expected to be on Enewetak at the end of September. 17 This van is intended as en operating spare replacement for the operating 18 vans. 19 - 4) PY SURVEY CRITERIA: a. 20 The AEC Task Group recommendations and general in mature. guidance were by design, 21 Subsequently, criteria have been developed by ERDA 22 to guide the in situ soil assay. © b. 23 A case-by-case evaluation by the CJTG (with the advice of the RCC) 24 of the requirements for soil removal, taking into consideration the location 25 C-2-E-4 tate b ved/ RAWwer ek tne ote peamermn SR . . cow von ee pe mR cee eee ,
