San Joaquin Delta Community College DistrictDraft Environmental Impact Report for <br /> Master Plan Implementation <br /> September 2006 <br /> result of potential releases of their contents. !f USTs are found to be present, the <br /> City of Stockton Fire Department should be notified and the USTs removed in <br /> accordance with applicable regulations. !f contaminated soil and/orgraundwater <br /> is present below the proposed project site, appropriate remedial,measures <br /> should be implemented in conjuncture with human-health risk evaluations to <br /> Protect current and future occupants of the property. <br /> Residual Impacts: Incorporation of mitigation HZ-4(a) and HZ-4(b) would reduce project <br /> impacts to less than significant. <br /> 3.6.5 Cumulative Impacts <br /> As discussed above, the proposed project is located in an urban area surrounded by primarily <br /> commercial properties that comprise at least 20 documented hazardous waste sites. These <br /> sites are in various stages of cleanup and remediation. The hazards at these sites are primarily <br /> associated with soil and groundwater contamination related to USTs and LUSTS. Excavation <br /> and construction at Delta College has a high potential to expose additional areas of <br /> contaminated soils which would require proper removal techniques, transport, disposal, and <br /> potentially soil remediation. In addition, demolition and remodel of multiple buildings would <br /> contribute to potential exposure of hazards to the surrounding community and also contribute <br /> substantially to the community's hazardous waste stream. Thus, construction activities at Delta <br /> College would contribute to ongoing cumulatively significant hazardous waste impacts related to <br /> risk of upset or accidental emissions. However, the project's contribution to these cumulatively <br /> significant impacts would be reduced to less than significant by the mitigation measures listed <br /> above. <br /> Page 3-142 <br />
