Furthermore, no additional Soldiers would bestationed at the base. Therefore, current levels of impacts to air quality, which are less thansignificant, would continue to occur.5.5.11.1.2 Impacts from Range ConstructionLess Than Significant ImpactsConstruction contractors would comply with the provisions of Hawaii Administrative Rules, Sec. 11-60.1-33 on Fugitive Dust as part of the requirements of construction contracts. Consequently,construction-related emissions would have a less than significant impaction on air quality. Impactfrom range construction at PTA also would be less than significant.Nitrogen oxide emissions are of concern primarily as an ozone precursor. Even though constructionemissions would increase, annual emissions of ozone precursors from construction activities would betoo small to have a measurable effect on ozone levels. Consequently, impacts would be less thansignificant.5.5.11.1.3 Impacts from Live-Fire TrainingLess Than Significant ImpactsLive-fire training would continue across the training areas at levels similar to levels discussed in the2004 Transformation EIS. Emissions from ordnance, military vehicles, and wildfires would continueat current levels, which result in less than significant impacts. Consequently, impacts under thisalternative are expected to continue to be less than significant.February 2008 5-230 2/25th SBCT Final EIS
Chapter 5 – Environmental Consequences5.5.11.1.4 Impacts from Maneuver TrainingLess Than Significant ImpactsManeuver training involves the movement of vehicles over large areas, which would generate dustand emissions. The levels of dust and emissions generated would be similar to those that occurredwhile training the 2/25 th ID (L). The Army has developed and implemented a DuSMMoP for thetraining areas. The plan addresses measures such as, but not limited to, restrictions on the timing ortype of training during high-risk conditions, vegetation monitoring, dust monitoring, soil monitoring,and buffer zones to minimize dust emissions in populated areas. With this plan, the impacts on airquality would continue to be less than significant.5.5.11.2 Alaska5.5.11.2.1 Impacts from Cantonment ConstructionLess Than Significant ImpactsUnder Alternative D, there would be no increase in Soldiers and no cantonment construction at FRA.On-going military activities would continue and new projects would be developed as needed. Impactsto air quality from dust and emissions would continue at current levels, which are less thansignificant.The following mitigation measures are currently implemented on USARAK lands and are part of theNo Action Alternative.• Continue to comply with asbestos and lead National Emission Standard for Hazardous AirPollutants during renovation or demolition activities when friable asbestos materials are present.• Continue to submit required construction permit applications to the Alaska Department ofEnvironmental Conservation.• Continue to collect PSD ambient air quality data.• Continue to monitor air quality.5.5.11.2.2 Impacts from Range ConstructionLess Than Significant ImpactsThe current number of Soldiers training at FRA and DTA would remain the same and no additionalranges would be constructed. Consequently, there would be no new impacts to air quality. Impactswould continue to be less than significant.5.5.11.2.3 Impacts from Live-Fire TrainingLess Than Significant ImpactsThe current number of Soldiers stationed and training at FRA and DTA would remain the same andthe number of required live-fire user days per year at FRA and DTA would continue to be nearcurrent levels. Thus, overall impacts to air quality would remain the same and would be less thansignificant.February 2008 5-231 2/25th SBCT Final EIS
