Chapter 5 – Environmental Consequenceswould add the use of 4 UAVs. This training would affect only slightly the restricted airspaceassociated with the training ranges on both Oahu and Hawaii Islands. The impacts to airspace areexpected to be less than significant.Energy Demand and Generation. Construction at SBMR and PTA could result in infrequent serviceinterruptions in order to connect new lines and extend service. This less than significant impact wouldbe temporary, and the length of disruptions would be minimized to the greatest extent possible duringthis period. Service would be returned to normal after construction. No impacts to energy use or costswould be associated with live-fire or maneuver training.Facilities. Although an IBCT would possess 434 more Soldiers and their Families than the 2/25 th ID(Light), it is still 663 fewer than the 2/25 th SBCT that was previously stationed at SBMR. Thefacilities at SBMR would be adequate to support the 4/4th IBCT. Impacts to facilities, public services,infrastructure, and utilities are expected to be less than significant.5.5 ALTERNATIVE D — NO ACTION BASELINE CONDITION OF THE2/25 TH ID (LIGHT)5.5.1 Summary of the Environmental Consequences of Alternative DTable 5-52 presents the potential impacts of implementing Alternative D as it is described in Chapter2. For each VEC, impacts from four activity groups were analyzed: Cantonment Construction, RangeConstruction, Live-Fire Training, and Maneuver Training. Impacts from the four activity groups aresummarized by a single impact rating for each area affected by the alternative. Details of each activitygroup’s impacts are presented below in the resource sections.Impacts to most resources would occur from continued use of Army lands. Construction and trainingactivities would continue to introduce or spread noxious weeds, potentially affect threatened andendangered species, and increase the possibility of accidental ignition of a wildfire. Institutionalprograms and mitigation measures would reduce these impacts to less than significant. Impacts fromwildfire would remain a significant impact in Hawaii and less than significant in Alaska andColorado.Continued Army training at all the alternative locations would continue to have potential significantimpacts to cultural resources. The implementation of several administrative mitigation measureswould reduce those impacts to less than significant.Noise levels from ordinance use at SBMR would remain at the current, already significant, levels.Noise levels at the other affected areas would remain less than significant.Impacts to land use and recreation, traffic and transportation, socioeconomics, hazardous materialsand hazardous wastes, wetlands, wildlife and habitats, air quality, noise, airspace, energy, facilities,and subsistence would all be less than significant or no impacts would occur.February 2008 5-192 2/25th SBCT Final EIS
