Ask <br /> KLEINFELDER <br /> File No. 20-3978-O1.W10 <br /> July 26, 1997 <br /> 4.13 Wash Areas And Tote Storage Area(File No. 20-3978-01.W14) <br /> Based on the results of the subsurface assessment conducted in this area, Kleinfelder had the <br /> following recommendations detailed in our report "Limited Phase II Soil Assessment, Vehicle <br /> Solvent Washdown Areas, Tote Storage Area and the Former Auto Shed, (Phase I ESA <br /> Recommendation Numbers 17 and 18), Former Spreckels Sugar Plant No. 2, 18800 South <br /> Spreckels Road,Manteca, California, (APN#221-180-04)"dated February 24, 1997: <br /> 1. The existing soil cuttings (a.k.a.... drilling returns) should be evaluated and properly <br /> disposed of by Atherton Kirk Development. Kleinfelder can assist the Atherton-Kirk <br /> Development in that disposal at the Client's request at an additional cost. <br /> 2. The equipment rinseate should be properly evaluated and disposed of by Atherton Kirk <br /> Development. Kleinfelder can assist Atherton Kirk Development in that disposal at the <br /> Client's request at an additional cost. <br /> 3. A copy of this report should be submitted to the PHS/EHD and the RWQCB for their <br /> consideration. This report and the conclusions and recommendations presented are <br /> subjected to the"Limitations"presented in Chapter 7 of this report. <br /> 4. Because of the low levels of UEHs present in the truck wash and former auto shed areas and <br /> the fact that the analytes detected are heavy-end (high number carbon chains) hydrocarbons <br /> which adsorb readily to the soil. No further investigation in this area appears to be <br /> appropriate. Because of the intended reuse of this area for commercial or light industrial use, <br /> no additional cleanup appears appropriate. <br /> 5. As mentioned in the background, the former hazardous materials bulk tote storage area <br /> includes a slab approximately 6 to 8 feet below existing grade utilized for the foundation <br /> system.. Because of the levels of UEHs and semi-volatile organic compounds (EPA Method <br /> 8270) present in the area of the former hazardous materials bulk tote storage area, it is <br /> recommended that the fill soils sampled between the slabs (the surface slab and the <br /> subsurface slab) during the removal (prior to development). Any contaminated soils <br /> encountered should be evaluated, mitigated, and/or removed and properly disposed of at that <br /> time. <br /> 20-3978-01.WI0/2017LI55 Page 29 of 50 Copyright 1997,Kleinfelder,Inc. <br />
