Mendocino Avenue, Stockton, California <br /> Dear Ms. Lagorio`. <br /> ESA has prepared the attached Site Investigation Workplan for the assessment of methyl tertiary-butyl ether <br /> (MTBE)in the soil and groundwater at the subject site referenced above. MTBE was detected in the soils <br /> beneath the former UST tank pit following the removal of a 4,400-gasoline tank in April, 2000. <br /> Concentrations of petroleum hydrocarbons(gasoline) were,either non-detect or at low concentrations. <br /> t <br /> We understand that because MTBE was detected in the soil,the Regional Water_Quality Control Board' <br /> (RWQCB) will likely require further soil:and groundwater assessment. As we discussed in our telephone <br /> conversation on March 15, 2000,the University of the Pacific (UOP)is attempting to complete a <br /> construction project and would like to expedite the necessary assessment and possible remediation of the <br /> MTBE. For this reason, we have prepared this workplan and attached the laboratory reports for the soil <br />. ., samples collected immediately following the removal of the UST. Mr. Vidal Pedraza, the San Joaquin <br /> County inspector at the UST removal, indicated during a previous discussion that his office had not yet 1 <br /> received the laboratory reports'. By preparing the workplan and attaching the laboratory reports, we hope to <br /> provide you the necessary information so that we can complete the assessment as soon as possible. We <br /> understand that you will assign this case following your review and provide us comments on the workplan. <br /> 1 We appreciate your help and look forward to working with your department throughout the course of this <br /> assessment. If you require additional information or have questions,please call me at(415) 896.5900 or <br /> Ms. Crystal Stech at(916)564.4500. <br /> - I <br /> r" Sincerely, <br /> j Peter B.
