7 pee qe, INTRODUCTION The advanced scientific knowledge derived from nuclear tests at the U.S. Atomic Energy Commission’s Eniwetok Proving Grounds requires a Ser BS The preparation of this report covering the period FY 59 through FY 62 is authorized by a letter from the U.S. Atomic Energy Commission, Santa Fe Operations Office, ET: PWS-2179, dated 20 February 1956, from the Deputy Director of the Test Division. eer: the celta RSS programs. Such reappraisals, together with recommendations for changes or additions to existing facilities, have been collected after each test operation in the form of Long-Range Improvement Reports. This report, covering the period FY 59 through FY 62, is a continuation of the Proposed Long-Range Improvement Report published 1 June 1956. NE REESpi = bette periodic reappraisal of available facilities to assure adequate support of test Two general classes of construction are normally undertaken at the Eniwetok Proving Ground: the construction of scientific stations, usually considered expendable, and the plant aquisition and construction (PAC) program. The PAC program, essentially a long-range plan of permanent support facilities, is the class of construction presented in this report. Some of the projects described in the June 1956 publication were com- pleted during FY 57 and FY 58. The remainder of the construction as then planned, together with additional requirements, forms the basis for this report which continues and augments long-range planning through FY 62. This report includes all new requirements of the military users, the scientific laboratories, the AEC test organization, and the supporting con- tractor, It also re-evaluates the projects carried over from the 1956 report according to the construction completed in 1958. The broadened scope of the program will necessitate careful planning for the utilization of real estate on both sites Elmer and Fred. To conserve space, all new permanent or semipermanent buildings of single or multistory construction should be oriented parallel to roads or existing permanent buildings. This need for complete utilization of ground area has prompted the extensive long-range plan for utilities included in this report. The expansion of utilities will increase the capacity of the basic or primary services to accomodate future requirements. A total of 140 projects are presented in the two volumesof this report. Volume I covers Site Elmer; Volume II, Sites Fred and Rex. Projects for Site Elmer are numbered FY 59-62-101 through FY 59-62-160; projects for Site Fred are numbered FY 59-62-201 through FY 59-62-282; the project lor Site Rex is FY 59-62-301. The drawings accompanying project descripflons are numbered to correspond to the project. Drawings FY 59-62-100 and FY 59-62-200 show the location of all projects proposed in the body af this report. | Design criteria and justifications for projects included in this report were developed from two sources, namely, military users and the AEC task sroups. Thecriteria for the projects requested by the military users through cadquarters Joint Task Force Seven were taken from:
