Chapter 5 – Environmental ConsequencesAdditional Mitigation 1: Access controls would be developed and implemented to ensure the safety ofall personnel; and warning signs would be posted on the boundary to prevent unauthorizeduse/trespass.Less Than Significant ImpactsConflicts with existing land uses and recreation resources or conflicts with land use or resourcemanagement plans or policies. Under implementation of this alternative, additional live-fire trainingwould occur as a result of an increased number of Soldiers training at both the existing and newranges. In addition, new weapons would be used at the BAX ranges at SBMR and PTA and the use oflarge caliber munitions would increase. SBCT training would result in an increased number ofSoldiers training at all ranges, thus increasing the number of rounds fired as well as increasedvehicular traffic. Increased noise, dust, or other indirect effects associated with this alternative are notexpected to affect off-post land uses. The surrounding areas are uninhabited lands within the SBMRand PTA installations. No residential areas, schools, hospitals, or businesses are expected to beaffected. These impacts would be localized to the vicinity around the ranges. Land to the north ofPTA includes the Kaohe Game Management Area, Mauna Kea State Park, Mauna Kea ForestReserve, and the Mauna Kea National Natural Landmark. Noise impacts at PTA are presented inSection 5.2.12, and show only very minor changes to noise contours following the proposed action.Mauna Kea and its associated recreational and natural areas are not expected to experience anynoticeable impacts from increased live-fire training at PTA. UXO would only occur within the impactareas, which are posted as restricted to public access. With continued implementation of currentArmy SOPs to minimize potential noise and safety impacts, impacts are expected to be less thansignificant. No additional mitigation would be required. No live-fire would occur at DMR or KLOA;therefore, impact analysis is not applicable.5.2.6.4 Impacts from Maneuver TrainingSignificant But Mitigable To Less Than SignificantImpact 2: Conflicts with existing land uses and recreation resources or conflicts with land use orresource management plans or policies. Under this alternative, maneuver training would occur atSBMR, DMR, KTA, and PTA. Brigade- and battalion-level training would primarily occur at PTA,and the frequency of maneuver training at PTA is not expected to increase above existing levels. TheKeamuku Parcel would be used for maneuver training as well, and would remain a nonlive-fire area.Platoon- and company-level training would primarily occur at the other areas, and would increase infrequency. Munitions use is not part of maneuver training; however, SBCT maneuver trainingtypically requires a larger area compared to current training, potentially extending training into areasthat have not been used as frequently. Training at DMR would occur in areas currently used for offroadmaneuvers, so impacts are expected to be less than significant.Regulatory and Administrative Mitigation 2: Mitigation measures for impacts to noise, biologicalresources, and dust and odors are presented in the respective sections of this document.Impact 3: Conflicts with existing land uses and recreation resources or conflicts with land use orresource management plans or policies. SRAA provides an additional 1,290 acres, some of whichmay be used for maneuver training. With implementation of the proposed mitigation, as describedbelow, training activities at SRAA are expected to result in significant but mitigable to less thansignificant to land uses.February 2008 5-32 2/25th SBCT Final EIS
