(c) If placement of either array is proceeding and a delay of 48 hr or more is announced, buoys planted must be recovered, Either the complete or partial array may then be set out as time and circunstances permit. A.5 RECOVERY PRCCEDURES Recovery operations are expected to commence on U day. Each ATF will recover orn buoys, commencing with stations in probable fallout. If recovery ships themselves enccunter faliout, they may retire and recover buoys in adjacent areas. Every effort shouid be made to recover the important stations as early as possible; however, if recovered buoys produce dangerously high radiation fields aboard ship, it may be neces- sary to break off and return to "nivetok to off-load. then return immediately to recover remainder.
