(bo) If placement of either the complete array or the partial array is proceeding and a 24-hr delay is announced, buoys already planted can be ieft to drift into new positions and additional buoys laid upstream at the proper time to round out the arrar. (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 partiel array may then be set out as time and circunstances permit. A.5 RECOVERY PROCEDURES Recovery operations are exnected to commence on U day. Each ATF will recover orn buoys, commencing with stations in probable fallout. If recovery ships themselves encounter fallout, they may retire and recover buoys in adjacent areas. Every effort shouid be made to recover the imvortant stations as early as possible; however, if recovered buoys produce dangerously nigh radiation fields aboard ship, it may be necessery to break off and return to “nivetok to off-load. The shins should then return immediately to recover remainder. A.6 MESSAGES TO ATFIS FROM CTG7,3 The following information should be included in messages to ATF's, (a) Message to proceed to lay tuoys should specify plan desired (complete or partial). Project will provide information. (b>) Message to proceed to recover buoys should indicate probable area of fallout by buoy designations. Project will provide information. (c) Messages to ATF's to modify laying procedures on-site should include specific recommendations, Project will provide information. A.7 MESCAGES FROM ATF'S TO CTG 7,3 (a) Each ship should report -rog.ass in laying operations every (c) Info CTG 7.1 on all messages. 4hr.
