Therefore, all future notifications, correspondence and reports submitted regarding the <br /> Site shall be addressed to Geoffrey Rader at the Central Valley Water Board office in Rancho <br /> Cordova. <br /> I have reviewed the 31 October 2016 Annual Groundwater Monitoring and Status Report <br /> (Report) submitted by Wayne Perry, Inc. on behalf of Equilon Enterprises LLC dba Shell Oil <br /> Products US (Equilon). The Report summarizes field activities and monitoring data associated <br /> with the first quarter and third quarter 2016 groundwater monitoring events. I have a few <br /> concerns with the Report, which I've summarized below. <br /> 1. A groundwater potentiometric surface map was not provided for 29 August 2016 <br /> monitoring well gauging data. <br /> 2. Monitoring and Reporting Program No. R5-2015-0820 (the MRP) requires groundwater <br /> samples from several wells to be analyzed for naphthalene. Based on the laboratory <br /> analytical reports included in Appendix A, naphthalene analyses were completed for <br /> several groundwater samples, however, these results are not presented in the Report <br /> text, tables, or figures. Please present these results in future reports. <br /> 3. In Figure 2 of the Report, monitoring wells MW-29 and MW-30 were given a symbol <br /> corresponding to the legend explanation "To Be Abandoned". The MRP requires that <br /> monitoring wells MW-29 and MW-30 be monitored on semi-annual and annual <br /> frequencies, respectively. Please do not abandon these wells, and instead correct Figure <br /> 2 in future reports. <br /> If you have any questions or concerns regarding the Site, this letter, or any future <br /> correspondence, I can be reached at (916) 464-4707 or via e-mail at <br /> geoff.rader@waterboards.ca.gov. <br /> KARL E.
