All BIKINI based personnel and equipment not directly involved ,. : In or essentialto late preparations and shot operations will be ..- phased to ENIWETOKATOLL or permanently redeployed prior to B minus possibly a small maintenance party on EBIRMAN)BIKINI ATOLLwill be evacuated of all personnel. The number of personnel on ERYU (and ENIRRAN) will be within the capability of helicopter lift. (b) In the event of excessive contamination of the ENINMAB . ISLAND camp, a limited capability will ezdst for indefinite operations from afloat. (c) Boat pool craft, not accompanying the evacuation to sea, will be either anchored in deep water in the southe,rn part of BIKIRI lagoon or beached on the EMINMARISLAND group or ENYUISLAND. (2) Shot #7 (KOQN), Total pre-shot evacuation of all personnel (less Firing Party on ERYU) will be necessary. Equipment not previously redeployed to ENIWETOKATOLLtill be relocated on ENW (and/ or BIKINI) ISUBTI prior to shot time, (3) Shot #L+ (ECHO) c There will be no pre-shot evacuation of personnel or materiel from E??IWETOKATOLL. Only the relocation of personnel, equipment and small craft from the northern islands to ENIWETOKand PARRYISLANDS will be necessary. (A) All ships of TG 7.3 will put to sea for each shot if not occupied in other operations at the non-involved atoll. Small craft at the affected lagoon which cannot be evacuated will be moored in deep water or placed ashore in areas affording greatest protection from blast, heat, wave action and radiological effects. (1) During the ENIWETOKoperations the joint task force will maintain a capability for emergency post-shot evacuation. An emergency post-shot evacuation will be executed on order of CJTF SEVDI in the event radiological contamination conditions so dictate. Such evacuation will be for personnel safety only and will not involve materiel or personal belongings other than toilet articles. Any such evacuation will be capable of accomplishment on four (4) hours (2) During shot phases at BIKCRI (H Hour to H/24 hours) personnel at ENIWETOKATOLLwill be in an alert status. Although remote,

Should excessivecontaminationbecome apparent, able aicraft,and specifiedtask force vesselswill proceed on order of CJTF SEVEN from BIKINIto IZNIWETOKto assist in the emergency evacuatfonof all endangeredpersonnel. c(l) above will then apply.
