Chapter 5 – Environmental ConsequencesImpact 2: Unexploded Ordnance. Training as projected under this alternative would lead to aproportionate increase in UXO and could also result in an increase in the spread of lead wastes on therange within live-fire impact zones. With implementation of Army SOPs, impacts are expected to beless than significant, and no additional mitigation is required.Regulatory and Administrative Mitigation 2: UXO would only be within the impact areas, which arefenced and posted as restricted to public access. Fort Carson would continue to implement theAmmunition Supply Point SOP for storage and transportation of additional munitions. The 62 ndExplosives Ordnance Detachment would continue to respond to discoveries of UXO for safe opendetonation in place or at Range 121. Protocols for removing, encapsulating, enclosing, or managingsources of lead are provided in Fort Carson’s Lead Management Plan (DECAM 2004e).5.4.9.4 Impacts from Maneuver TrainingLess Than Significant ImpactsPetroleum, Oils, and Lubricants. Implementation of Alternative C would result in increased use ofpetroleum-based products in the cantonment at FTC and the training areas at PCMS. POLs that wouldbe used at the PCMS include gasoline, diesel fuel, oil, and lubricants used during routinemaintenance. Under this alternative, fuels would continue to be stored in ASTs and USTs at PCMS.The use of Stryker armored vehicles for training is expected to result in increased fuel transport andadditional refueling operations in the field to support training requirements. The risk of petrochemicalspills is expected to increase slightly under this alternative. The PCMS would continue to implementthe SPCC Plan (DECAM 2004j) and USTs and ASTs (DECAM 2004k) to minimize potential adverseeffects from accidental leaks resulting from the storage of additional petroleum products. Withcontinued implementation of Army SOPs, impacts to human health and safety are expected to be lessthan significant. No additional mitigation is required.Hazardous Materials and Wastes Use and Management. In addition, the increased maneuver trainingthat would occur under this alternative may contribute to the potential for generating hazardous waste.Hazardous materials that would be used at FTC and PCMS include pesticides; chemical agents; andexplosive and pyrotechnic devices used in military training operations. With implementation of theArmy protocols and SOPs, impacts to human health and safety are expected to be less thansignificant.5.4.10 Biological ResourcesTable 5-46 lists the types of impacts on biological resources that would occur under Alternative C.Impacts to wetlands, vegetation, noxious weeds, threatened and endangered species, habitats, andgeneral wildlife are presented. No direct impacts to wetlands from cantonment and range constructionor live-fire and maneuver training are anticipated at FTC or PCMS. If future training or constructionactivities have the potential to affect wetlands, the Army would coordinate with USACE to assessimpacts and mitigation for disturbance of wetland areas. Most direct impacts to wetlands would beavoided, and those that cannot be avoided would be mitigated through the Section 404 process (eitherthrough complying with the FTC /PCMS regional permit or by applying for coverage under anationwide permit).February 2008 5-163 2/25th SBCT Final EIS
