CHAPTER I, SECTION 1 of considerable concern because of the always present possibility that an employee may claim damagesas a result of such overexposure. CAMP OPERATIONS Quarters, facilities and services were operated by Holmes & Narver to house, sustain and support all personnel of Joint Task Force SEVEN, except those who lived on site Fred and in Naval vessels. To accomplish this, tem- porary camps at Tare, Charlie, Fox, Nan and Ursula were provided and the permanent camp at Elmer was expanded. Each camp contained all necessary facilities for housing, messing, PX store, barber shop, refreshment bars, mail, laundry and utilities. ed), The total peak population (H&N support- including all sites and all groups, was reached on 28 February, 1954, with a total of 3398.

This was accomplished by operation of landing craft, water taxis, DUKWs, barges and tugs by the Holmes & Narver boat pool, augmented during the operational phase by craft from a U.S. Navy boat pool. Transportation between Atolls was supplied by Task Group 7.3 by means of regular LST trips with occasional trips of an LSD or other types of vessels. Air transportation between Atolls was pro- vided in the initial phase by means of PBMs which were made available on a non-scheduled basis. On 30 January 1953, a C-47 made the first landing on the Peter-Oboe airstrip, shown in plan drawing, thereafter this Figure 2-47, Chapter II, and type of plane was regularly scheduled. At the start, the schedules provided for two flights per week, but this frequency was increased as the need arose and eventually reached four flights per day. Intra-atoll air transportation at Bikini was provided by heli- copters solely, thus eliminating the need for building airstrips at the various sites. The service provided by these craft proved of material assistance because of the helicopter’s ability to land small working parties at isolated locations. Intra-atoll air transportation at Eniwetok was provided by small liaison planes of the L-13 class and by helicopters. Due to a shortage of pilots, this service was considerably curtailed during the months of June, July and August of 1953, necessitating additional water taxi service. MAINTENANCE The problem of preservation and mainten- ance of the facilities and structures was inten- sified by the rapid corrosion and deterioration of substantially all ferrous materials due to the tropical atmosphere and salt spray prevalent at both Atolls. Frequent chipping or sandblasting and painting of metal surfaces was necessary except on aluminum buildings, which were comparatively maintenancefree. Continuous preventative maintenance pro- grams were established. Operating periods of equipment were recorded and overhaul was placed on a scheduled basis. Due to the distance of the Jobsite from the source of supply, it was essential that an adequate supply of spare parts be maintained at all times. SUPPORT SERVICES In accordance with Job IV of the Contract, support was provided to the Scientific agencies in assisting them in instrumentation and related work. This work was controlled by the initiation by the User of a Job IV work order, which required approval of the AEC Resident Engineer before the work could be undertaken. As of 1 June 1954, a total of 1479 Job IV work orders had been CASTLE. executed during OPERATION Support Services - Job IV Subsidiary Accounts include a detailed account of support services rendered to the various Using Agencies and Task Groups. These included five JFT SEVEN Task Groups and 11 Task Units, together with 9 Scientific Programs and 52 Scientific Projects applicable thereto. ROLL-UP and TEST OPERATIONS Prior to the first detonation, the Charlie camp was completely rolled up and the camp at Fox was reduced to a size to support 75 men for 10 days. After the Bravo event, roll-up of the Tare and Nan camps proceeded under adverse working conditions. (Refer to Chapter VII, Section 2). Roll-up of the Scientific Sta- tions not needed for test purposes proceeded as a parallel operation with the roll-up of all other facilities. With the cancellation of the Echo event, the roll-up of the camp on Ursula was accomplished. All equipment, materials and supplies not intended for post-test use were scheduled to be preserved, made ready for future use. mothballed, and Page 1-9
