he Operation of Utilities during Roll-up. Following the experiments, it will be necessary to have operators for the utilities on Eniwetok. In addi- tion to these, a small but competent crew of utilities personnel will be re- quired to weatherproof and maintain utilities provided for Parry and the Experiment Islands. Power plants in concrete emplacements on Experiment Is- lands and other equipment left in place rather than stored, should be visited, checked and operated frequently. It is'possible that mechanics in accomplish- ing these duties could accompany the regular security patrol. Units in serve ice in power and water plants should be rotated in sequence to keep them dehumidified, lubricated, and in operating condition, and consequently useful for a future series of tests. Other Services. After evacuation of the Atoll by scientific, military and construction forces concerned primarily with the tests, the contractor should maintain a nuclear force to preserve all incidental items as are conSidered worthy. These services would include proper storage of furniture and equipment that require moving from place of use to warehouse, the application of protective measures on items not requiring moving to warehouse for pro- tection, maintenance of transportation and construction equipment not returned to the Zone of Interior or reclaimed by the Armed Forces. Other services may include routine tests on submarine signal and communications cables for determination of rate of deterioration and other repetitive observations, the resurvey of terrain in shot areas to determine blast effects, the completion of "As Built" drawings not previously accomplished during Phases III and IV, and either the preparation or the furnishing of data for the preparation of the "Completion Report", VII - 3
