Inter-Island Transportation. The transportation of people, equipment and materials between useful islencs of the Atoll should be provided for by a consideration of island inter-connection, air and surface transport, and the economies of pertinent facilities and structures. Electrical Power. Electrical power should meet exacting requirements of operating reliability and voltage regulation. lconomic studies should be made of feasible alternate solutions to the problems of generation and distri-= bution. Power should be provided for the islands of iniwetok, Parry, Ani- yaanii, each shot island and Coral Head. Water Supply. A dual water supply should be provided on each residential island; a salt water system and a fresh water system. Waste Disposal. Adequate sewage collection systems, and sanitary dis- posal of sewage, trash and garbage should be provided on each residential island. Maintenance. Repair and maintenance of existing utilities and buildings at Eniwetok Island and Parry Island, as well as proving ground facilities elsewhere in the Atoll, should be vroposed. PLANNING: Selection of Shot Islands. The determining factors in a choice of shot locations are unit area and geographical separation. Among the requirements of a shot island, or group of islands used together for one shot, are: (a) that the Zero Towers be at least three miles apart, (b) that the Zero Towers be remote from the Control Station and, (c) that the Timing Stations must not be closer than one thousand yards from zero. These requirements eliminate the use of any island for a tower location III = 3
