Chapter 5 – Environmental Consequences(Light). The 4/25 th requires modernized ranges to complete training. Moreover, the 4/25 th is anairborne IBCT unit. This airborne capability would be retained within U.S. Army Pacific(USARPAC) as part of the 4/25 th re-stationing to SBMR. Requirements to conduct UAV training andairborne training would require additional facilities and an increased use of airspace in Hawaii.5.3.17.1 Construction and Training Requirements of the 4/25 th IBCTDescriptions of activities involving the realignment of the 4/25 th IBCT to SBMR are presented insection 2.6. They are summarized below to provide context for the impact analyses that follow.Cantonment ConstructionNo additional IBCT-specific cantonment construction would be required. The 4/25 th has the requiredadministrative offices, housing and vehicle maintenance facilities. In addition, the Soldiers andFamilies of the 4/25 th would have access to adequate schools, medical and quality of life facilities.Training Range and Training Infrastructure ConstructionTo meet the IBCT’s need for modernized ranges, the majority of the projects identified in the 2004Transformation FEIS that are not yet started would be completed. Transformation projects in progressbut enjoined would be completed. Projects described in Table 2-13 as non-SBCT specific projectswould be completed as part of this alternative. The designs of the projects, their intended uses, andanticipated impacts as presented in the 2004 Transformation FEIS have not changed and areincorporated by reference.Two additional range projects would be needed to support the 4/25 th ’s re-stationing to Hawaii. ACALFEX-capable range would be built in the footprint of the PTA BAX to support up-to-companylevel collective live fire training events. This CALFEX range would be approximately the samedimensions as the PTA BAX and would fit within the BAX’s planned 2,075 acre constructionfootprint. At the SBMR BAX site, an IPBC would be constructed. An IPBC is approximately 988acres, and would be configured to fit within the BAX footprint at SBMR.Parachute rigging and storage facilities would be sited in an existing 30,000 square foot storagewarehouse at WAFF (Figure 2–9). The warehouse was originally constructed as part of the multipledeployment facility for the SBCT. No impacts would be expected from the change in the use of thewarehouse at WAAF.An approximately 1,040-acre drop zone would be sited on the eastern portion of the Keamuku Parcel(Figure 2-12) to support airborne training drops of paratroopers and air drops of heavy equipment ofthe 4/25 th from C-130 aircraft. Preparation of the drop zone would include limited grading andclearing activities. This area has previously been used for airborne operations.Five jump towers would be constructed for airborne training on the SRAA (Figure 2–11). The jumptowers would be approximately 15 feet by 15 feet at the base of the tower and 35 feet high. The jumptowers would be constructed on undisturbed ground.Live-Fire TrainingLive-fire training for the IBCT is not expected to differ greatly from the historic training frequency orintensity of the 2/25 th ID (L). The 4/25 th would fire approximately 6.9 million rounds of munitions incomparison to the approximately 7 million rounds of munitions fired by the 2/25 th ID (L).
