h l Qi» Ane ee aeanteMee oe PART Ili, CHAPTER 7 7.19 AEC and HEN security personnel were assigned to Johnston Island in June, 1958, and TG 7.5 Pass and Badge Office was established on 16 June 1958. All cleared JTF-Seven personnel at Johnston Island wore green badges, and all others were required to wear red badges, Special “No Clearance” badges from the EPG interim badge system were used to denote uncleared H&N personnel working there as “Good Security Risks.” 7.20 The controls on photography at EPG as set forth in SOP 205-5, were followed by both TG’s 7.1 and 7.5. At the request of this Headquarters, CIC personnel of Headquarters, JTF-Seven, conducted a survey of all TG 7.1 photographic processing and issuance points. Compliance with control regulations was generally satisfactory; however, certain deficiencies were brought to the attention of the CTG 7.1 and later corrected. TG 7.5 photo processing points were checked by AEC security personnel and were found to comply with the prescribed regulations. ! 7.21 A security survey of AECintérests at the EPG was conducted by inspectors of the Office of Security, ALO, during the period 25 Mayto 1 June 1958, and it was found that, in general, the EPG security program was functioning satisfactorily. ROLL-UP 7.22 The last test detonation at Bikini occurr- ed on 22 July 1958. All classified infor- mation was removed from that atoll, and the Military Police departed on 1 August. The Marine guards of TG 7.3 were relieved from further guard responsibilities at EPG on 22 July. 7.23 The last test detonation at Johnston Island occurred on 1] August 1958. All classified activities of TG’s 7.1 and 7.5 ceased on 18 August, at which time the military security guards were no longer required. 7.24 The last shot at Eniwetok Atoll occurred on 18 August 1958. The operational phase was concluded on 15 September 1958. Responsihility for the custody, security, and accountability for unexpended test materials (SS materials at the EPG reverted to the Manager, ALO, on the latter date. All SS materials left the EPG for return to the Mainland by 20 August 1958. Classified documents and other materials, other than those to be maintained at the EPG by the AEC andits Contractors, were removed by the same date. 7.25 The Military Police closed their last guard post at the EPG on 20 August 1958, and departed for the States. The HARDTACK badge system was deactivated on 9 September 1958, and was replaced by the EPG interim badge system which had been suspended during the HARDTACK,Phase I, operational period. PUBLIC INFORMATION PROGRAM 7.26 Responsibility for issuing all public information materials concerning Operation HARDTACK, Phase I, rested with the Joint Office of Test Information in Washington, D. C. The staff of JOTI was made up of AEC and DOD public information personnel, with a representative of AEC’s Division of Information Services as Director. 7.27 In addition, a military public information officer was assigned to the staff of the Commander, JTF-Seven. 7.28 Public announcements of individual detonations were generally confined to those for which the yield was more than 200 kilotons. Duringthe series, a total of 16 detonations were announced. 7.29 The Director of ALO’s Office of Information was assigned as a Liaison Officer to the Joint Task Force on the staff of JOTI for the PINON (open shot) event of Operation HARDTACK,Phase I; however, the event was cancelled during the latter part of the program. CLASSIFICATION 7.30 Prior to Operation HARDTACK, Phase I, representatives of the Classification Offices of ALO, SAN, FC/AFSWP, LASL, UCRL, and Sandia Corporation met to revise and rewrite the Classification Guide for the Pacific Test Operations. The revision agreed upon was submitted to AEC, Washington, and AFSWP, and after their approval it was forwarded to JTF-Seven where it was approved for use in Operation HARDTACK, Phase I. 7.31 The Chief of the Classification Branch of the Classification Division, AEC, Washington, was designated as Chief Classification Officers for JTF-Seven. His alternate was the Chief of the Declassification Branch of the Classification Division, AEC, Washington. 7.32 Direct participation of the ALO Classi- fication Division in the Marshall Islands phase of the Operation was rather limited and, in the main, was handled by communication with Albuquerque. A representative of the ALO Classification Office was in residence at Eniwetok and Bikini Atolls as the Classification Officer for TG 7.5 for a period of three weeks. Since mostclassification problems arose within TG 7.1, which had its own classification representatives, there was relatively little demand for a resident classification representative for TG 7.5 affairs. 7.33 Major involvement of the ALO Classification Division started with the Johnston Island phase of Operation HARDTACK Page 55 _
