LFR Inc. <br /> Soil was excavated-and additional soil samples were collected until concentrations were <br /> below determined levels. <br /> The following subsections provide a —77777-77 <br /> summary of previously submitted <br /> reports regarding the four <br /> generalized areas (former waste <br /> disposal areas, burn-pile areas, lead- <br /> affected soil area, and pyrolytic oil- <br /> affected soil areas) where <br /> confirmation soil sampling was <br /> conducted. <br /> 5.4.1 Former Waste Disposal Areas 00 <br /> Three reports were submitted to the <br /> CIWMB, DTSC, and RWQCB Photograph 9 <br /> presenting the results of Collecting soil samples for laboratory <br /> confirmation soil samples collected analysis <br /> from three former waste disposal <br /> areas: <br /> • Analytical Results for Stockpile Soil Samples Collected from Small Waste Disposal <br /> Area, Tracy Tire Fire Site, San Joaquin County, California, prepared by LFR and <br /> dated April 30, 2003 <br /> • Analytical Results for Soil Samples (AA, BB, and CC) Collected from Small Waste <br /> Disposal Area, Tracy Tire Fire Site, San Joaquin County, California, prepared by <br /> LFR and dated May 21, 2003 <br /> • Analytical Results for Soil Samples (DD, EE, and FF) Collected from Small Waste <br /> Disposal Area, Tracy Tire Fire Site, San Joaquin County, California, prepared by <br /> LFR and dated May 21, 2003 <br /> Based on the waste characterization results in the three reports, LFR determined that <br /> the soil was either Class I RCRA hazardous waste, Class I non-RCRA hazardous <br /> waste, or non-hazardous Class II waste. LFR advised the contractor (SCI) to coordinate <br /> transportation and to contact the appropriate California licensed landfill(s) for disposal <br /> of the excavated wastes. The confirmation soil sampling results confirmed that the <br /> hazardous concentrations of metals were successfully removed from the three waste <br /> disposal areas. <br /> 5.4.2 Lead-Affected Soil Area <br /> During January 2003, a slab of solidified lead was encountered on top of the soil in the <br /> northern area ("lead-affected soil area") of the Site as shown in Figure 2. The CIWMB <br /> project engineer determined that the slab of lead was a remnant of an illicit, on-site, <br /> Page 18 rpt-RA_summ-Nov06-final-09025:FNC <br />
