RADIOLOGICAL CLEANUP OF ENEWETAK ATOL|
potential use of the item by the dri-Enewetak and took into account
criteria established by the TTPI and DNA. This volume also containeg
proposals for mobilization, base camp construction, cleanup, anq
demobilization, using contractor forces. Cost estimates and cleanup work
estimates were based on preliminary standards furnished by DNA for both
radiological and nonradiological cleanup. The nonradiological criteria
served as a basis for future plans and much of the actual cleanup. The
radiological criteria were changed many times before that part of the
cleanup could begin.32

The Engineering Study described several options for disposition of
contamination, none of which were adopted, but which continued to be
proposed as alternatives in subsequent planning conferences. These
included:
. Covering contaminatedsoil with a blanket of clean soil.
b. Dumping contaminated debris in the craters on Runit.
c. Dumping contaminated debris and soil in the lagoon.
d. Dumping contaminated debris and soil in the ocean.
e. Shipping contaminated debris and soil to the continental United
States (CONUS) for storage.33
VolumeII was an assembly of large maps of each of the islands. Each
map showed the location of each structure, item of construction, junk pile,
concrete strip, and test station, as well as stands of vegetation and other
natural features. Also shown were such items of radiological interest as
contaminated burial areas, contaminated scrap piles, and other radioactive
debris.
VolumeIII contained detailed and summary cost estimates. The total
estimated cost (in 1972 dollars) for cleanup, including dumping
contaminated debris in the Runit craters and spreading 62,000 cubic yards
of clean soil on Enjebi, was $28.8 million using foreign contractor
personnel and $18.4 million using military troops. Options added $1.4
million for ocean dumping of contaminated material or $4.3 million for its
return to the United States.34
Before the Engineering Study data could be incorporated in an EIS,
more information was required on DOI’s rebabilitation plans and AEC’s
radiological cleanupcriteria.
ENEWETAK RADIOLOGICAL SURVEY:
OCTOBER 1972-OCTOBER 1973
On 13 September 1972, AEC-NV was directed to plan, organize, and
conduct a radiological field survey to develop sufficient data on the total
radiological environment of Enewetak Atoll to: (1) locate and identify
