. SD a a a PART Ill, CHAPTERS 1 and 2 information on these operations, refer to Chapters III and IV. 1.13 Plans for JTF-Seven Weather/Rad-Safe _ Stations called for the re-activation of stations at Rongerik, Kusaie, Ujelang, Rongelap, Wotho, Kapingamarangi, and Tarawa and the construction of new facilities at Utirik, Nauru, Ponape, and Truk. The Chief, Eniwetok Branch, AEC, handled the negotiations for sites and clearances directly with the U. S. High Com- missioner, Trust Territories, Pacific; the British Resident Commissioner, Tarawa; and the Australian Administrator, Nauru, Central Pacific Islands. For entry to Nauru, it was necessary to obtain permission from the Australian Govern- ment, through the U. S. State Department, Washington, D. C. After considerable delay, permission was granted and a lease agreement was concluded in time to permit completion of construction prior to the beginning of the Operaion. 1.14 Detailed plans were made by H&N for the recruitment of personnel, oreration and management of camp and support facilities, off-atoll operations, hostile action alerts, natural disaster defense, and for the radiological safety of its own personnel. 115 E-7, TG 7.5, assisted by the OTO RadSafe Adviser and the AEC Rad-Safe Officer, made detailed plans for TG 7.5 RadSafe operations and supervised their execution. This planning included the use of IBM equip- ment to prepare accurate and rapid Rad-Safe records. Refer to Chapter XI for details on TG 7.5 Rad-Safe operations. 1.16 TG 7.5 natural disaster defense and hostile action alert plans were prepared and included in the TG 7.5 SOP. 1.17 Plans were also made for the roll-up of the EPG and off-atoll Weather/RadSafe Stations after the completion of Operation HARDTACK.The roll-up of Bikini Atoll began after the JUNIPERevent and was completed on 19 August. The roll-up of the off-atoll Weather Stations began on 26 July with the departure of the LST-618 for Nauru, and Weather Station roll-up was completed on 16 September 1958. The roll-up of Johnston Island began on 14 August and was completed by 19 September 1958. Eniwetok Atoll roll-up was essentially complete by 1 October 1958. 1.18 A revised long-range plan for PAC improvements to EPG was submitted in June 1958 in two volumes entitled LONG- RANGE IMPROVEMENT PLANNING—1959 THROUGH 1962 — ENIWETOK PROVING ‘ GROUND. VolumeI covers Site Elmer; Volume II covers Sites Fred and Rex. Someof the pro- jects described in the June 1956 publication of the same general title were completed during FY’s 1957 and 1958. The remainderof the con-. struction as then planned, together with additional requirements, forms the basis of the new report which augments long-range planning through FY 1962. CHAPTER 2 PERSONNEL PHASING; 2.1 TG 7.5 manpower was phased with construction and support requirements. Construction personnel recruitment fell below estimated rates in 1957. (See Fig. 3-1). This reduced manpower requirement was caused by rescheduling the construction program. 2.2 Due to recruitmentdifficulties, it became necessary to work engineering and critical craft personnel up to 84 hours per week during peak activity periods. This factor, together with the extended build-up period, held the TG 7.5 population below the estimated peaks. TG 7.5 population fell off sharply during the latter part of April but remained higher than originally planned due to an increase in the number of events scheduled and additional construction requirements. Another factor affecting the TG 7.5 population level was the transfer of the VHA events from Bikini to Johnston Island. TG 7.5 peak population at Johnston Island was 380 on 12 July 1958. Page 40 2.3 Personnel of Task Groups supported by TG 7.5 exceeded scheduled numbers by approximately 150 and reached a peak of 2330 on 14 May 1958. The personnel build-up of Task Groups supported by TG 7.5 wasslightly in advance of original predictions but reached the peak as scheduled. The reduction of person- nel of the various Task Groups was gradual, until after the cancellation of the UN event when numbers were reduced sharply. 2.4 With the completion of the HARDTACK, Phase I, series, TG 7.5 began the roll-up program and subsequently reduced personnel strength. It was planned that TG 7.5 strength would be reduced to approximately 1200 by 1 October 1958. Plans also indicated that TG 7.5 interim strength would not fall below 900, as- suming a normal 18-month interim period. & 2 2 2 = = 0000000000€¢¢0¢¢@000@ 88288 8B BR BB #@ —__ > &@&»=»=—STO
