bi sity of special skills, carefully selected from the construction forces would be retained for this purpose. The time required for these operations begins with the completion of major construction features and extends to the moment of the actual tests. Utilities Operation. The operation and maintenance of such utilities as power generation, transmission, communications, water works, sewer lines, roads and airstrips, and fuel handling and storage, will require only a limited nunber of such skills as diesel mechanics, electricians, telephone operators and repairmen, linemen, still operators, construction equipment operators am laborers. Personnel whose training and familiarity with specific equipment, loca- tion amd function of appurtenances and general operating routine of each independent utility has been developed during the major construction program, will be retained beyond that period to insure a complete smooth working installation for the primary benefit of the scientific experiments. The knowledge of this personnel with regard to spare part requirements and spare part stock levels will also be advantageous. It is anticipated that demands on all utilities will increase from interim construction requirements to a maximum during the period wherein scientific personnel arrive at the Atoll. The demands would remain at this peak level dure ing active preparation for the experiments and during the actual tests... The greatest demands on an experiment islam utilities would thus be made in the period just prior to the shot. At this time, it will also be necessary to pro- vide operators on each experiment islani for operating power plants, communica- tions facilities, ani water distillation units. Prior to zero hour, salvageable material would be removed. Personnel forn- erly housed on these experiment islands would be removed to base camps on Parry and Eniwetok islands. VI =-5
