Chapter 5 – Environmental Consequencesno impacts to the wetland are expected. The three regulated wetlands at SBER are also distant fromthe maneuver areas. No impacts to wetlands would occur at KTA, PTA, or SBMR from maneuvertraining. No mitigation is necessary for wetland impacts from maneuver training. SOPs and BMPsdesigned to minimize impacts to wetlands through stormwater and erosion control would be followed(see Section 5.2.2 Soil Erosion and 5.2.3 Water Resources).5.2.11 Air QualityTable 5-14 lists the types of impacts associated with air quality that would occur under Alternative A.The impact from range construction would be mitigable to less than significant. Live-fire trainingwould be less than significant. The level of impact from maneuver training would be less thansignificant with mitigation with the exception of PM 10 emissions generated from wind erosion atKeamuku Parcel, which the Army considers to be a significant impact.Table 5-14Summary of Potential Impacts to Air Quality from Alternative ALocationActivity Group SBMR DMR KTA/KLOA PTAImpacts from Cantonment Construction N/A N/A N/A N/AImpacts from Range Construction N/A Impacts from Live-Fire Training ☼ N/A ☼ ☼Impacts from Maneuver Training / N/A = Significant + = Beneficial Impact = Significant but mitigable to less than significant N/A = Not Applicable☼ = Less than Significant = No Impact5.2.11.1 Impacts from Cantonment ConstructionThere is no cantonment construction required in USAG-HI to support the stationing of the 2/25 th .USAG-HI has adequate facilities on hand to support the SBCT and, in fact, was supporting theSBCT’s living, administrative, and vehicle maintenance requirements in 2007 prior to the unit’sdeployment.5.2.11.2 Impacts from Range ConstructionSignificant Impacts Mitigable To Less Than SignificantImpact 1: Fugitive dust from construction activities. Construction of a BAX at SBMR and PTA andtrail construction at DMR would temporarily increase fugitive emissions from activities atconstruction sites. Construction contractors would comply with the provisions of HawaiiAdministrative Rules, Sec. 11-60.1-33 on Fugitive Dust as part of the requirements of constructioncontracts. Consequently, impact from range construction at SBMR and PTA would be significant butmitigable to less than significant.Regulatory and Administrative Mitigation 1: The Army would develop and implement a Dust andSoils Mitigation Monitoring Plan (DuSMMoP) for the training affected areas. The plan would addressmeasures such as, but not limited to, restrictions on the timing or type of training during high-riskconditions, vegetation monitoring, dust monitoring and control measures, soil monitoring, and bufferFebruary 2008 5-55 2/25th SBCT Final EIS
