Aurora Street <br /> Stockton, California <br /> Dear Ms. Duncan: <br /> In discussion with JJW Geosciences, Inc., Mr. John Cervantes of JC Trucking concurred with <br /> our recommendation to use the ozone Injection system approved by San Joaquin County EHD <br /> for groundwater remediation to remediate the soil contamination in the vadose'zone beneath <br /> the former UST excavation site. JJW discussed cost reimbursement with a representative from <br /> the State Tank Fund for soil remediation utilizing the ozone system that is to be installed for <br /> groundwater remediation. The Tank Fund representative stated that there should not be any <br /> problems with reimbursement since any additional costs related to the soil cleanup would be <br /> minimal if any. <br /> If it is determined that the contaminated soil is not being remediated satisfactorily, after a <br /> sufficient period of time has elapsed, additional remediation efforts specific to the soil <br /> contamination can be considered and will be proposed. <br /> Mr. Cervantes is currently working with PG&E to establish electrical service to the site for the <br /> operation of the ozone system. The time estimate for PG&E to provide service is approximately <br /> four more weeks from now. JJW expects the ozone system delivery to be within eight weeks <br /> from electric service hook-up. JJW is estimating eight weeks for installation and report writing. <br /> JJW is planning on having the ozone system assembled, installed, and operating and a report <br /> submitted to the San Joaquin County EHD by the end of May 2004. <br /> If you should have any questions please feel free to call the undersigned. <br /> Respectfully, <br /> JJW GEOSCIENCES INC. <br /> Mark Jerpbak, R.G. <br /> cc: John Cervantes,JC Trucking <br /> James Barton, CVRWQCB <br /> 11350 Monier Park Place, Rancho Cordova, CA 95742 Tel: 916.853.8025 Fax: 916.853.8029 <br />
