r+ <br /> Results of Initial Investigation and Work Plan December 18, 1990 <br /> ARCO Service Station No. 2076, Lodi,California AGS 30008.2 <br /> further investigation of soil conditions beneath the tanks. Vapor-recovery wells could be <br /> installed in these borings if remediation of soil is warranted. <br /> LABORATORY ANALYSES <br /> ® Soil samples collected from the bottom of the existing and proposed tank cavities will be <br /> submitted to a State-certified laboratory for analysis of TPHg by EPA preparation Method <br /> t 5030 and modified EPA Method 8015 and BTEX by EPA Method 8020. Soil sample <br /> collectedJfTom under the former leaded gasoline tank will be submitted for analysis of total 1 <br /> and orgacns-.lead. Laboratory results will be discussed with ARCO personnel and with <br /> ARCO's approval forwarded to the SJPHS. A copy of a signed Authorization to Release <br /> i . <br /> Analytical Data form is included in Appendix C of this work plan. The new tanks will be <br /> installed after the SJPHS receives the laboratory reports and approves tank installation. <br /> k Y f <br /> OBTAINING APPROVAL FOR TANK INSTALLATION <br /> With ARCO's approval, laboratory results and a sample location map will be provided to <br /> the SJPHS to expedite the installation of the new underground storage tanks. The letter of <br /> R; <br /> acknowledgment,included in Appendix C of this work plan, commits ARCO to submitting <br /> k <br /> either a Soil Contamination Work Plan or a report on the tank removal investigation within <br /> ;< <br /> 3 months of completing the field work. If laboratory results indicate TPHg concentrations <br /> { greater than 10 ppm and BTEX concentrations greater than 1.0 ppm remain in place at the <br /> ® base of either excavation,Applied GeoSystems will recommend that ARCO submit the Soil <br /> Contamination Work Plan within 3 months of completing the field work...The Work Plan <br /> _will describe proposed procedures for further delineation of hydrocarbons in soil not <br /> q � <br /> l <br /> `� 15 <br /> 4 <br /> APPIled 000SYWOMS <br />
