The 40 and 400 pCi/g criteria recommended for use in

decisiocs on cleanup of contaminated soil at Enewetak have noc been

changed or made more stringene since the Task Group repors was

issued in 1974.

In the EIS, soil Levels below 40 pCi/ga vere

judged sot to require cleanup.
This is seill our recommendation.
it was tacommended {n the EIS that soils having greacer shan 4Q0
pCi/gm snould be cleaned up wherever these Levels wer2 fsund.
This

is also still our recommendation. The value of -~CO pCi/g is to be
used by JNA in the cleanup of the Aomon crype. Islands having soz: .
