UXO could affect the construction of the proposed ranges onSBMR and PTA. Construction would involve moving soils that could be contaminated with UXOfrom prior activities in the range ordnance impact area. Construction would be preceded by Armysponsoredsurface and subsurface clearance and if necessary followed by ordnance health and safetymonitoring during construction in order to reduce potential exposure and impacts from this project.Although UXO presents a significant impact, USAG-HI would follow proper abatement techniques,which would reduce this impact to less than significant. In addition to these mitigation measures, theArmy would continue to educate Soldiers on how to identify UXO and the proper safety proceduresfor handling UXO. With continued implementation of standard Army regulatory and administrativerequirements, impacts associated with UXO are expected to be less than significant.Regulatory and Administrative Mitigation 1: Before the start of any construction activities, the Armywould employ qualified personnel to conduct a UXO survey of the proposed construction area. If therisk of encountering UXO is low, then UXO construction support would be used. If the risk ofencountering UXO is high, then UXO clearance would be performed to ensure the safety of the site.The Army would document UXO surveys and removal actions in full accordance with applicablelaws, regulations, and guidance. The Army would perform UXO clearance activities if rounds arefired outside of designated impact areas or present an immediate threat to human health or safety.Continued implementation of standard Army regulatory and administrative requirements, wouldreduce this impact to less than significant.Impact 2: Lead. Construction activities could involve lead exposure to workers in the form of leadbasedpaint. Implementing the mitigation below would reduce the impacts to less than significant.The construction of ranges would redistribute material from berms that will be removed or alteredFebruary 2008 5-41 2/25th SBCT Final EIS
