CALIFORNIA REGIONAL WATER QUALITY CONTROL BOARD <br /> CENTRAL VALLEY REGION <br /> NPDES NO. CA0084255 <br /> MONITORING AND REPORTING PROGRAM NO. 98-062 <br /> FOR <br /> SETTLING DRY CLEANING DEFENDANTS <br /> LINCOLN VILLAGE CENTER <br /> GROUNDWATER TREATMENT SYSTEM <br /> SAN JOAQUIN COUNTY <br /> This Monitoring and Reporting Program contains minimum monitoring and reporting requirements <br /> necessary to determine compliance with the Waste Discharge Requirements Order No. 98-062. <br /> Monitoring requirements are established for the different phases of the groundwater treatment system <br /> operation: the treatment performance evaluation and the full-scale operation. <br /> TREATMENT PERFORMANCE EVALUATION MONITORING <br /> The objectives of this phase are to monitor the performance of the extraction well and to determine the <br /> effectiveness of the treatment system to meet effluent limitations. The treatment performance evaluation <br /> (TPE) consists of three separate phases that have greater quantities of extracted and treated ground water <br /> with each phase. During the first TPE phase, the Discharger shall sample the influent to and effluent <br /> from the treatment system 30 minutes after start-up and every 30 minutes for the parameters listed below. <br /> During the second TPE phase, the Discharger shall sample the influent to and effluent from the treatment <br /> system one hour after start-up and every four hours for at least eight hours for the parameters listed below. <br /> During the third TPE phase, the Discharger shall sample the influent to and effluent from the treatment <br /> system one hour after start-up and every eight hours for at least 40 hours for the following parameters: <br /> Constituent Units Type of Sample <br /> pH pH units Grab <br /> Specific Conductivity µmhos/cm Grab <br /> VOCs' µg/1 Grab <br /> BTEX2 µg/1 Grab <br /> Total Petroleum Hydrocarbons µg/1 Grab <br /> Lead(total) mg/1 Grab <br /> Oxygenate Compounds' µg/1 Grab <br /> Total Volume of Water Treated gallons <br /> Influent and Effluent Flow Rate <br /> at Time of Sampling gpm <br /> Water Level in Extraction Well feet msl <br /> Extraction Rate at Time of Sampling gpm <br /> By EPA Method 601 or equivalent. <br /> 2 BTEX=benzene,toluene,xylene and ethylbenzene by EPA Method 602 or equivalent. <br /> ' By EPA Method 8260. All detected compounds shall be reported. <br />
