Weber Avenue Third Floor <br /> Stockton, California 95202-2708 017/131593-003/1 <br /> Subject: Air Sparge / Soil Vapor Extraction Design Drawings, <br /> T&T Trucking, Lodi, California <br /> Dear Mr. Infurna: <br /> In July 2006, Brown and Caldwell submitted the Soil Vapor Extraction (SVE) and <br /> Air Sparge (AS) Pilot Test Letter Report on behalf of T&T Trucking, Inc. to the <br /> San Joaquin County Environmental Health Department and GeoTracker. In <br /> summary, the results of the AS/SVE pilot test indicated that AS/SVE technology <br /> appeared to be effective in removing volatile organic compound (VOC) mass from <br /> soil and groundwater. Therefore, a design for a full-scale AS/SVE remedial action <br /> was recommended to be completed and submitted to San Joaquin County <br /> Environmental Health. <br /> As we discussed by phone on February 5, 2007,we are forwarding a hard copy of <br /> the full-scale AS/SVE Remediation System Design for your review. While an <br /> electronic copy of the design drawings will be uploaded to GeoTracker, there is a <br /> significant delay before documents are available for viewing or downloading from <br /> the website. T&T Trucking is interested in beginning construction of the fuIl-scale <br /> remediation system in Spring 2007 to expedite remediation and ultimate closure of <br /> the site before the State Fund sunset date of January 1, 2011. We would <br /> appreciate your review and approval of this approach so remediation may begin <br /> without delay. <br /> P:\31000\131593-']'&'] Trucking AS-SVE llesi�,m\Corrcspondencc\7'ransmittal J to Final Plans to]nfurna.doc <br /> Environmental Engine ers & ConsmItants <br />
