3 Project Objectives <br /> 3.1 Project Task/Sampling Objectives <br /> The U.S. EPA directed the START to prepare this FSP to further evaluate environmental <br /> conditions at the subject property. A better understanding of environmental conditions will <br /> enable the CSRA to make decisions regarding redevelopment of the property for commercial <br /> use. <br /> Soil and groundwater sampling followed by laboratory analysis will be implemented to <br /> accomplish the project objectives. Specific sampling objectives include the following: <br /> • Assess potential contamination to soil on the site. <br /> • Assess potential contamination to groundwater on the site. <br /> Analytical data collected as part of this TBA will be used to answer the following site specific <br /> study questions: <br /> • Are the COPCs present at concentrations that exceed site specific action levels in soil? <br /> • Are the COPCs present at concentrations that exceed site specific action levels in <br /> groundwater? <br /> 3.2 Action Levels <br /> • Site specific action levels proposed for COPCs at this site are based upon established <br /> general screening levels by regulatory agencies in the region for many of the COPCs. The <br /> data collected during this project will be used to evaluate the El Concilio No. 1 Site and <br /> develop site-specific clean-up goals.The lowest established screening levels will be used <br /> as the minimum standard for laboratory reporting limits for the COPCs. Each COPC is <br /> presented in Tables 1 and 2 with its relevant screening levels. <br /> The following screening levels were reviewed to determine the lowest action level for the <br /> COPCs: <br /> • U.S. EPA Industrial Regional Screening Levels, December 2009(soil only) <br /> • U.S. EPA Maximum Contaminant Levels, December 2009(groundwater only) <br /> • California Regional Water Quality Control Board Industrial Environmental Screening <br /> Level,May 2008 (soil and groundwater) <br /> • California EPA California Human Health Screening Levels,January 2005 (soil only) <br /> A summary of available actions levels with the lowest action levels highlighted in bold for this <br /> project is presented in Tables 1 and 2 (Appendix B). <br /> 14.002693.1401.OIBR 3-1 <br /> EI Co ilio No.I <br />
