Chapter 5 – Environmental Consequences5.5.11.2.4 Impacts from Maneuver TrainingLess Than Significant ImpactsThe current number of Soldiers stationed and training at FRA and DTA would remain the same andthe frequency and intensity of maneuver training at FRA and DTA would continue at near currentlevels. Thus, overall impacts of maneuver training to air quality would remain the same and would beless than significant.5.5.11.3 Colorado5.5.11.3.1 Impacts from Cantonment ConstructionLess Than Significant ImpactsThe current number of Soldiers stationed and training at FTC and PCMS would remain the same.However, some additional cantonment facilities would be constructed to meet the needs of theunaccompanied Soldiers that are currently housed off post. Construction of these projects wouldcause only temporary impacts to air quality in the form of dust and vehicle emissions. Afterconstruction is completed, dust and emissions from vehicular travel on FTC would be similar tobaseline conditions. Consequently, impacts to air quality would continue to be less than significant.5.5.11.3.2 Impacts from Range ConstructionLess Than Significant ImpactsUnder the No Action alternative, no range construction projects are currently planned. Therefore, noadditional dust or air emissions would be generated from construction. The overall impacts to airquality would be less than significant.5.5.11.3.3 Impacts from Live-Fire TrainingLess Than Significant ImpactsUnder the No Action alternative, training activities at FTC would remain the same as current levelsand the number of required live-fire user days per year at FTC would be at current levels. Emissionsfrom ordnance, military vehicles, and wildfires would continue at current levels, which result in lessthan significant impacts. Prescribed burn activities would continue to minimize the potential forwildfires sparked by live-fire training are anticipated to continue, but will be dependent on manyfactors such as drought and meteorological conditions. However, FTC would continued to adhere tothe requirements of AQCC Regulation No. 9, Open Burning, Prescribed Fire and Permitting, toensure that conditions are acceptable for prescribed fires and that air quality is not compromised(DECAM 2003b). Consequently, impacts to air quality would continue to be less than significant. Nolive-fire training would occur at PCMS.5.5.11.3.4 Impacts from Maneuver TrainingLess Than Significant ImpactsThe current number of Soldiers stationed and training at FTC and PCMS would remain the same andthe frequency and intensity of maneuver training at FTC and PCMS would continue at current levels.February 2008 5-232 2/25th SBCT Final EIS
Chapter 5 – Environmental ConsequencesThus, overall impacts of maneuver training to air quality would remain the same and would be lessthan significant.5.5.12 NoiseTable 5-63 lists the types of impacts associated with noise that would occur under Alternative D.Under the No Action Alternative, the 2/25 th SBCT would not be stationed at any of the alternativelocations, and therefore no SBCT-specific impacts to noise would occur.

With multiple items of equipment operating concurrently, noise levels can berelatively high during the day at locations within several hundred feet of active construction sites. Thezone of relatively high construction noise levels typically extends to distances of 400 to 800 feet fromthe site of major equipment operations. Locations more than 1,000 feet from construction sitesseldom experience significant levels of construction noise.Construction activities would generate average daytime noise levels of about 55 dBA at the closestnoise-sensitive area. Because incremental Ldn contributions from construction activities would belower than 65 dBA at the nearest noise-sensitive areas (1,950 feet distant), impacts from constructionnoise would be less than significant. Most other construction projects would be further removed fromnoise-sensitive locations than the projects discussed above.
