Mr. Timothy VanDomelen - 4 - 9 May 2008 <br /> J.R. Simplot, Lathrop, San _iquin County <br /> y <br /> 13. MRP Section C.9 requires annual sampling for VOCs in the vadose zone monitoring <br /> network. Pages 118-121 of Part Three of the Annual Report infer that the lysimeters <br /> were empty all year, yet the tables on pages 83-99 suggest that sample collection was <br /> possible in April, July, or October for all lysimeters. Please provide sampling and <br /> analytical data for VOCs as required by the MRP in your next quarterly report, due <br /> 1 August 2008. <br /> 14. In all future quarterly and annual report submittals, please provide the contract laboratory <br /> and any in-house analytical data reports as an appendix in the form of a CD inserted in <br /> the report. <br /> 15. Because of the number of lysimeters, monitoring wells, and structures sampled on this <br /> project and in the interests of long-term continuity on the project. we recommend that the <br /> Annual Reports furnish comprehensive tables listing all sampling location details, and <br /> maps showing monitoring well, sump, and pond lysimeter locations. The tables should <br /> include the sampling location identifier, date installed, construction information (e.g., <br /> casing diameter, casing material, slot size, top and bottom of screen, top and bottom of <br /> filter pack, depth to water, groundwater elevation, surveyed elevation, as applicable), and <br /> aquifer zone (if appropriate). <br /> We appreciate J.R. Simplot's timely submittals and its efforts to comply with the MRP as <br /> discussed above. Your next quarterly report is due 1 August 2008. If you have any questions <br /> regarding this correspondence, please contact me at (916) 464-1588. <br /> Kathryn L.
