SECTION 3 <br /> FINDINGS <br /> 3.1 Laboratory Results <br /> The results of the sampling and testing performed as part of this investigation are presented in <br /> the following section. Please refer to Data Summary Table 1 through Table 4 in Appendix B <br /> for a summary of the laboratory results. The boring logs are provided in Appendix C, and the <br /> analytical laboratory reports and chain-of-custody forms are included in the Appendix D. <br /> Sage separated the results from the Phase I1 Investigation to differentiate the work necessary to <br /> close out the RECs or Other Concerns identified by ENVIRON from the work necessary to <br /> establish a baseline of the existing environmental conditions at the plant, although all of the <br /> Sage work constitutes the baseline. <br /> 3.2 RECs or Other Concerns <br /> 3.2.1 Long Industrial Use of Site <br /> Results of the soil sample collected from SB-1 (Current Hazardous Waste Storage <br /> Area)indicated that no VOCs were detected above the method detection limits in this <br /> soil sample. <br /> Results of the soil sample collected from SB-2 (Former Paint Booth Area)indicated <br /> that no VOCs were detected above the method detection limit in this soil sample. <br /> 3.2.2 Former AST Containment Staining <br /> Results of the soil samples collected from SB-3 and SB-4(Former AST Storage Area) <br /> indicated that no VOCs were detected in any of the soil samples. <br /> 3.2.3 Historical Agricultural Use of the Site <br /> Results of the soil sample collected from HA-I indicated that no Pesticides or <br /> Herbicides were detected above the method detection limits in this soil sample. <br /> 3.2.4 On-Site Sumps <br /> Results of the sediment samples collected from Sump NE Field and Sump NW Field <br /> indicated TPH detections in the soil sample above the laboratory detection limits. <br /> Results from the sample collected from Sump NE Field indicated a TPH DRO level of <br /> 47.0 mg/kg and TPH ORO of 820.0 mg/kg. Results from the sample collected from <br /> Sump NW 1 Field indicated a TPH DRO level of 94.0 mg/kg and TPH ORO of 920.0 <br /> mg/kg. All of the sump samples collected are below the San Francisco Bay RWQCB: <br /> commercial screening levels of 180 mg/kg for TPH DRO and 2,500 mg/kg for TPH <br /> ORO. <br /> Sage Environmental Consulting,L.P. 3-1 Westlake Chemical Company <br /> July 2013 Lodi,CA,Phase II Investigation <br />
