Hunter <br /> Stockton , CA 95204 <br /> Subject: Canepas Car Wash <br /> 6230 Pacific Avenue <br /> Stockton CA Site Code: 1225 <br /> The San Joaquin County Environmental Health Department (EHD ) has reviewed site <br /> data and two reports: Quarterly Report — Second Quarter 2008 (2nd QR 2008) dated <br /> August 22, 2008 , prepared by Advanced GeoEnviron mental , Inc. (AGE ), and First <br /> Quarter 2008 Groundwater Monitoring Report and Treatment System Status Update ( 1st <br /> OR 2008) dated May 2, 2008, prepared by Condor Earth Technologies (CET). <br /> The EHD letter dated February 15, 2008 noted that if a new remedial technology is <br /> appropriate for your site, you need to submit a feasibility study to the EHD for review to <br /> evaluate the feasibility and cost effectiveness of the proposed remediation alternative. <br /> The letter also noted that the lateral and vertical extent of the dissolved contaminant <br /> plume still has not been defined and additional site investigation is needed . The EHD <br /> has not received a feasibility study or any workplans to conduct additional site <br /> investigation . Although the UST Cleanup Fund reimbursement for your site was <br /> projected to be depleted in June 2008 , the EHD must require that adequate measures <br /> be taken to pursue site closure in accordance with state law regardless of availability of <br /> monies from the State Cleanup Fund . <br /> In the 2"d OR 2008 , AGE recommended evaluation of new remedial alternatives that <br /> may be more cost effective and that the current remediation system be shut down <br /> indefinitely. CET informed the EHD by telephone on October 30, 2008 that the soil vapor <br /> extraction (SVE) and groundwater extraction system (GWE) remediation system have <br /> been shutdown since April 2008 . The EHD concurs with the shutdown of the remediation <br /> system and the recommendation to evaluate potentially more cost effective remedial <br /> alternatives. The EHD directs that the feasibility study for additional remediation be <br /> submitted by January 14, 2008. <br /> AGE also recommended the following actions : <br /> • petroleum fuel fingerprinting analysis to determine the source(s) of the <br /> contamination <br /> • conducting a soil vapor survey to evaluate the potential risk of contaminant vapor <br /> migration <br /> • collection of soil samples to assess the residual mass of petroleum hydrocarbons <br /> following soil remediation . <br /> 081208directive <br />
