RADIOLOGICAL CLEANUP OF ENEWETAK ATOLL
Runit, aggregate from an old stockpile on Enjebi was used. In Novembe,
1977, the JTG began quarry operations at the site designated in the quarry
permit issued by POD, i.e., on the reef just south of the Runit hotline
(Figure 8-17). Quarry operations were constrained by the time and height,
of tides which did not always coincide with normal working hours, [,
December 1977, permission was granted to billet troops overnight op
South Runit to facilitate quarrying at low tide and to save timelost jp
commuting from Lojwa Camp.*!
A crushing and screening plant, obtained from existing Department of
Defense (DOD) assets, was installed near the quarry. Its capacity was
morethan adequate to keep the project supplied with aggregate (Figures 8.
18, 8-19, 8-20). Crushed coral rock was processed and separatedinto four
sizes: 1-1/2 inches and larger, 3/4 to 1-1/2-inch aggregate, 3/4-inch to
number 4 aggregate, and fines. The latter three sizes were used for the
production of clean concrete. When the plant began operations, the
aggregate was washed, but this step was later dropped as unnecessary.
The Commander, JTG (CJTG) was able to work around manyofthe
planning and scheduling constraints on Runit site preparation. Runit
construction also was constrained by shortages of plumbing andelectrical
supplies caused by a severe winter in the eastern United States, as was
other camp construction at Enewetak. Nevertheless, Runitstockpile sites
were ready to accept contaminated debris and soil from the otherislands
