C A M B R I A Regional Water Quality Control Board (CVRWQCB) Shell is not reluctant to perform investigations? During the meeting we could not recall any such request made by the CVRWQCB, or any other sites where we are performing 1,2-DCA investigations. After the meeting we looked into this matter to see if we have any other ongoing or historical 1,2-DCA investigations, specifically with the CVRWQCB. We do not have any other 1,2-DCA investigations, historical or current, in the Central Valley region or anywhere in Northern California. If this site were overseen by the CVRWQCB, and they requested us to investigate for 1,2-DCA under the same circumstances, we would have produced the same work plan for them as we did for EHD. © EHD requested we collect a groundwater sample from the water supply well at the mobile home park located southeast of the subject site. We will contact the management of the mobile home park, and if they agree to allow us access to the well, we will collect a water sample. As mentioned by EHD, should we encounter any resistance to our request to sample their water supply well, we will advise EHD and request help in gaining access to the well. Pursuant to the request made by EHD in correspondences on several Shell cases to report all EPA Method 8260B peaks as well as the discussion during the meeting that the Regional Board would like to see all constituents within the gasoline range reported, Shell has verified with its lab, Severn Trent Laboratories in Pleasanton, California, that the value reported as "TPHg" on the Certified Analytical Reports essentially includes all industry standard petroleum hydrocarbon analytes that elute within the C6 to C12 range except for MTBE, TBA, and DIPE. Therefore, a gasoline constituent that is detected in a sample is automatically reported as part of the TPHg value, i.e.,all peaks are reported. Additionally, since this"report all peaks"request originates from the CVRWQCB, Shell plans to discuss this matter further with them to better clarify the goal of this request and the issues involved with this request. Cambria will contact the CVRWQCB. As previously requested by EHD for several Shell cases and as is usual practice for Shell for EHD, all soil and groundwater monitoring well samples are analyzed for TPHg, BTEX, MTBE, TBA,DIPE,TAME,ETBE,ethanol,methanol, 1,2-DCA, and EDB unless it has been established that any of these constituents is not present either by previous soil analysis or by four consecutive quarterly groundwater sample analyses in each monitoring well. The same holds true for TPHd if diesel fuel was sold by Shell at the service station location.
