NTS field crews located a site identified as 05-22-15 at the GMX fenceline on 17APR-96 and conducted a GPS survey. A marker for the actual CAS could not be found, but an old photo was found in the field files indicating that the package had previously been retrieved. Also found was a May 1992 memo to DOE/NV with a list of CASs that had been cleaned; the list included 05-22-15. y/ No Further Action Required at Corrective Action Site
