322 RADIOLOGICAL CLEANUP OF ENEWETAK ATOLL c. Do not clean Runit. d. Clean Runit within available resources following northern islands cleanup. The arguments for cleaning Runit had been presented during the deliberations on island priorities. Option b was recommended by Fielg Command to assure optimum use of resources and to demonstrate an earnest effort to accomplish the EIS mission by removing the highest leve} contamination on the atoll. Initially, this cleanup would be accomplisheg with trucks and front loaders located on Runit for the cratering operation when they were not so employed. Since there was little soil stockpiled to begin the crater containment operations, an appreciable amount of highlevel Runit material could be excised and used to keep the containment operation going. Eventually, after other soil cleanup was complete, all the soil removal equipment would be used to clean Runit. Option c was based on the premise that, if the island would be quarantined because of subsurface contamination, resources should not be wasted on any attempt to clean the island. The Director, DNA decided that cleanup of hot spots on Runit would be accomplished as a mission secondaryto the otheractivities on that island. That is, no special resources would beallocated to the cleanup but, when those resources already on theisland; e.g., front loaders, trucks, etc., were not otherwise committed, they would accomplish this cleanup. Thefinal amount of Runit cleanup would depend on the resources available after completion of other contaminatedsoil cleanup. !2!.122 CRATER CONTAINMENT DECISION There was a wide divergence of views on the alternatives for crater containment. The five alternatives presented were: a. Dispose of all excised soil and radioactive debris in the crater. b. Dispose of contaminated soil from islands other than Runit in the crater up to zero height; add debris, cover with soil, and cap. Spread remaining contaminated soil on north Runit. c. Dispose of 160 pCi/g-contaminated soil in crater to zero height; add debris, cover with soil, and cap. Spread lower level contaminated soil on north Runit. d. Do not use crater for contaminated soil disposal. Place contaminated debris in crater and cover with soil from ejecta and other locationsto above zero height. Spread excised soil on north Runit. e. Do notusecrater for disposal. Place contaminated debris on land and cover with soil from other islands. Stabilize soil surface with vegetation. ®y
