Box 2009 <br /> Stockton, California 95201 <br /> Subject: Site Assessment and Request for Closure <br /> Sears Auto Center No. 1288 i <br /> 5110 Pacific Avenue <br /> Stockton, California <br /> Dear Mr. Knoll: <br /> On behalf of Sears, Roebuck and Co. (Sears), IT Corporation (IT) is responding to agency <br /> comments regarding the Site Assessment and Request for Closure document dated <br /> February 10, 2000, for Sears Auto Center No. 1288 located at 5110 Pacific Avenue, Stockton, <br /> California. <br /> As per our telephone discussion on April 19, 2001, it is understood that there is a question <br /> regarding the analytical results associated with soil samples collected at the subject site in August <br /> 1994 during fuel dispenser and product line removal activities. The soil analytical results in <br /> question are listed in Section III of the Underground Storage Tank Closure Review Form dated <br /> October 1, 1998, which is found in Attachment 3 of Appendix C in the Site Assessment and <br /> Request for Closure document(a copy of the form is also attached to this correspondence). The <br /> analytical results listed in Section III of the review form are intended to be the "Maximum <br /> Documented Contaminant Concentrations'for soil samples collected in August 1994 during fuel <br /> dispenser and product line removal activities, and were taken from Tables 1, 2 and 3 found in <br /> t <br /> Appendix C of the Site Assessment and Request for Closure document. The soil analytical <br /> results shown on the review form list total petroleum hydrocarbons as gasoline (THP-g) at a <br /> maximum concentration of 4,8.00 milligrams/kilogram (mg/kg). As I mentioned during our t <br /> discussion on April 19, 2001, this TPH-g result is in error. <br /> Tables 1, 2 and 3 (Appendix C, Site Assessment and Request for Closure document) summarize <br /> the soil analytical data from the GTEL Environmental Laboratories, Inc., (GTEL) reports (also <br /> found in Appendix C). Both the tables and the GTEL reports that accompany the tables, indicate <br /> that the soil samples collected during fuel dispenser and product line removal activities in August <br /> 1994 contained a maximum TPH-g concentration of only 5.8 mg/kg. Therefore,the TPH-g <br /> concentration of 4,800 mg/kg listed on the review form is in error. <br /> skrCAW INOOW S0ESKT0M042301-doc <br />
