Herrigfeld <br /> Herum Crabtree Brown <br /> 2291 W. March Lane, Ste. B-100 <br /> Stockton, CA 95207 <br /> REVIEW QUARTERLYREPORT— THIRD QUARTER 2003, FORMER CONNELL MOTOR LIFT <br /> TRUCK/RIVER CITYPETROLEUM, 2211 NORTH WILSON WAY,STOCKTON, SANJOAQUIN <br /> COUNTY <br /> I reviewed the Quarterly Report—Second Quarter 2003 Monitoring Report(Report), dated 1 October <br /> 2003, submitted on your behalf by Advanced GeoEnvironmental Inc. (AGE). The Report provides <br /> quarterly groundwater monitoring data for the Stoddard Solvent(TPHss) spill near a dry well located on <br /> the property. The Report recommends implementing a TPHss Corrective Action Plan (CAP) for the Soil <br /> Vapor Extraction/Air Sparging (SVE/AS)remediation proposed by AGE in 2002. <br /> The TPHss and onsite River City Petroleum 1,2-dichloroethane (1,2-DCA) groundwater plumes are <br /> commingled. The 2002 AGE CAP was limited to the dry well spill area and did not address remediation <br /> of the adjacent Underground Storage Tanks (USTs) release site. My 15 September 2003 letter requested <br /> that future remediation proposals, workplans and reports be combined for both sites to address the entire <br /> commingled plume in a cost effective manner. A single document, combining a Site Conceptual Model <br /> (SCM), an Additional 1,2-DCA Investigation Workplan, and a revised Interim Remedial Workplan for <br /> SVE/AS, is requested by 15 November 2003. A revised CAP is requested by 15 December 2003. <br /> If you would like to discuss your site in a meeting with Regional Board staff at our office located at <br /> 10365 Old Placerville Road, Suite 210, Sacramento,please contact me at(916) 255-3050 or <br /> bartopj arb5s.swrcb.ca.gov. <br /> james L.
