nature and extent of the remaining soil contaminant mass in the subsurface and the estimated <br /> horizontal extent of groundwater contamination in the first groundwater zone; (7) Generation of <br /> a Site Conceptual Model of the soil and groundwater contamination at the site; and (8) <br /> Conclusions and recommendations. A digital copy of the report and all figures and tables will be <br /> provided in a .pdf image format to the RWQCB. <br /> 6.6.2 Remediation Feasibility Study <br /> This section discusses the Remediation Feasibility Study(RFS)methodology that will be <br /> implemented. This technical scope of work contained in the site assessment work plan has been <br /> formulated to identify and map the location of any VOC impacted areas believed to be present in <br /> the vadose-zone soil (<60 feet bgs)beneath the LNC site. <br /> The Remediation Feasibility Study will include the following elements: <br /> • Identify and evaluate appropriate standards <br /> • Develop remedial action objectives <br /> • Identify remedial action alternatives <br /> • Evaluate remedial action alternatives and select preferred alternatives <br /> These tasks will be generally consistent with NCP requirements and The Guidance for <br /> Conducting Remedial Investigations and Feasibility Studies Under CERCLA (USEPA, 1988) <br /> (RDFS Guidance). <br /> Identify and Evaluate Appropriate Standards <br /> This portion of the Remediation Feasibility Study will identify and evaluate the appropriate <br /> federal, state, and local standards used to assess the ability of various alternatives to achieve the <br /> remedial action objectives. Standards will be evaluated with respect to their applicability to the <br /> site and the level of protectiveness required to satisfy remedial action objectives. <br /> M ain\D:AEnvironmenta1\LN CV\10152007.wpd 43 <br />
