CALIFORNIA REGIONAL WATER QUALITY CONTROL BOARD <br /> CENTRAL VALLEY REGION <br /> DRAFT MONITORING AND REPORTING PROGRAM <br /> FOR <br /> FLAG CITY LIMITED PARTNERSHIP <br /> BOKIDES FAMILY LIMITED PARTNERSHIP <br /> FIRST INVESTMENT FLAG CITY CORPORATION <br /> AT <br /> FLAG CITY CHEVRON <br /> 6421 CAPITOL AVENUE,LODI <br /> SAN JOAQUIN COUNTY <br /> The subject site is an operating gasoline service station utilizing underground storage tanks (USTs) <br /> from 1984 to present. The property is currently owned by the Bokides Family Limited Partnership <br /> and operated by the First Investment Flag City Corporation. Cleanup and Abatement (C&A) <br /> Order No. 5-00-700, issued on 1 March 2000, ordered Flag City Chevron to investigate and clean <br /> up petroleum hydrocarbons and MtBE leaked from the UST system at this site and submit <br /> quarterly reports. Following two years of remedial actions, decreasing concentrations of MtBE <br /> and a reduction in plume size are documented in groundwater monitoring and sampling reports. <br /> This Draft Monitoring and Reporting Program(MRP),proposed pursuant to Section 13267 of the <br /> California Water Code, is designed to direct groundwater sampling and monitoring in order to <br /> monitor contaminant plumes and determine whether remedial efforts are effective. The Discharger <br /> shall not implement any changes proposed in this MRP until it is issued by the Executive Officer. <br /> Once issued by the Executive Officer,this proposed MRP will replace the quarterly monitoring <br /> and reporting requirements listed in C&A Order No. 5-00-700. An NPDES surface water <br /> discharge permit is also in effect at this site, and this draft MRP does not affect the monitoring and <br /> reporting requirements of the NPDES permit. <br /> GROUNDWATER MONITORING <br /> Currently 26 monitoring wells (MW-1 through MW-12D),ten extraction wells (EW-1 through <br /> EW-10), two County Service Area(CSA)wells, and the treatment system influent and effluent <br /> sample ports are part of the Flag City monitoring program. This proposed groundwater monitoring <br /> program will include all 40 sample locations and any additional wells installed subsequent to the <br /> issuance of this MRP, and will follow the schedule below. Monitoring wells with free phase <br /> petroleum product or visible sheen shall be monitored for product thickness and depth to water <br /> only. Sample collection and analysis will continue to follow standard EPA protocol. <br />
