EI Dorado, Stockton <br /> Importance: High <br /> Frank, <br /> i <br /> Nice talking with you this afternoon. I just want to confirm what we agreed upon regarding your October 11, 2007 <br /> letter to Shell regarding the referenced site. <br /> Item 1)Source Contamination: CRA will address this item following completion of site investigation activities as <br /> discuss below. This will allow us to obtain additional site assessment data including vertical assessment data <br /> which will help prepare a more thorough response. Therefore, the due date of 12/3/07 for item one is no longer <br /> applicable. We will implement site investigation and reporting following approval of our pending work plan. <br /> Item 2) Further Site Assessment Needed: We will submit a site investigation work plan by December 3, 2007 to <br /> urther assess the vertical and horizontal extent of impacted soil and groundwater beneath the site as warranted. <br /> An updated SCM will be submitted with the site investigation report following completion of field work. <br /> ,/Item 3)Source of PCE and TCE: Our file review did not identify the location of the waste oil tank. I am trying to <br /> get copies of Shell's historical files to hopefully figure out where it was. Hopefully, I will have the files before work <br /> plan submittal. I will give you an update in the work plan. <br /> Item 4) 1,-DCA and EDB: I have made the changes to the groundwater monitoring program as requested. <br /> Let me know if you have any additional comments or questions. <br /> Thanks, <br /> Mike <br /> Mike Murphy <br /> Conestoga-Rovers &Associates (CRA) <br /> 19449 Riverside Drive, Suite 230 <br /> Sonoma, CA 95476 <br /> P.
