Chapter 5 – Environmental Consequencesremediation at IRP sites, the use of hazardous materials or generation of hazardous wastes duringconstruction, and increased fuel usage during SBCT maneuver training. Mitigation would beimplemented to minimize impacts as summarized in the following subsections.Table 5-28Summary of Potential Human Hazardous Material and HazardousWaste from Alternative BLocationActivity Group Fort Richardson Donnelly Training AreaImpacts from Cantonment Construction ☼ N/AImpacts from Range Construction ☼ N/AImpacts from Live-Fire Training Impacts from Maneuver Training ☼ ☼ = Significant + = Beneficial Impact = Significant but mitigable to less than significant N/A = Not Applicable☼ = Less than Significant= No ImpactEach facility maintains strict SOPs and SPCC plans for hazardous materials and waste. Potentialimpacts to human health and safety would be mitigated by conformance with the existing Armyprotocols and SOPs as summarized in the mitigation described with the impact analysis. Withimplementation of existing Army SOPs, potential impacts associated hazardous materials and wastesare expected to be significant but mitigable to less than significant.5.3.9.1 Impacts from Cantonment ConstructionLess Than Significant ImpactsContaminated Sites. None of the facilities to be constructed as a part of this alternative would belocated on land with known contamination. However, construction excavation can expose soilscontaminated by historic uses of sites. An Excavation Clearance Request (dig permit) must beobtained prior to any excavation activities. Any discovered contaminated soil or groundwater wouldnot be removed from construction sites without written approval from an authorized USAGAKrepresentative. Should contamination be discovered during preconstruction or construction,appropriate soil remediation would be implemented. These methods would be agreed upon by theArmy, USEPA, and ADEC. Standard spill prevention measures would be taken during construction.If contaminated soils are exposed during construction, impacts are expected to be significant;however, with implementation of standard Army administrative and regulatory requirements, impactswould be reduced to less than significant.Lead and Asbestos. During renovation or demolition of older buildings to clear the way forconstruction of new facilities, LBP and asbestos may be encountered and removed, and couldtemporarily generate small amounts of hazardous waste. All operations involving hazardous wastewould be accomplished in accordance with USAGAK Pamphlet 200-1, Environmental Quality:Hazardous Waste, Used Oil, and Hazardous Materials Management, and ADEC regulations andcontinued implementation of Army SOPs would result in less than significant impacts. No additionalmitigation is required.February 2008 5-99 2/25th SBCT Final EIS
