EXCESS ATTAPULGITE DISPOSAL
As the container cap was being completed, another disposal problem
becamecritical. Only 38 percent of the attapulgite anticipated in the design
was used. This resulted in the need to dispose of over 14,000 bags which
remained on theatoll. After several months of seeking local solutions, the
JTG reported the excess in June 1979. 139
Attempts were made to find other government agencies with a
requirementfor the attapulgite. One was located in Louisiana; however,it
was determined that the cost of repackaging the bags, which had
deteriorated badly at Enewetak, and shipping them to New Orleans would
exceed the cost of new attapulgite. Other disposal methods, such as lagoon
dumping or spreading it on the Fig-Quince area of Runit, were rejected on
environmental grounds. On 13 September 1979, the JTG was authorized to
seal the excess attapulgite in existing concrete bunkers on Runit. The
bunkers were marked to identify permanently the material they
contained. 140
