Ed Koberstein page 3 <br /> Current trends within the State Water Resources Control Board (SWRCB) indicate that <br /> only sites that have thoroughly investigated and fully assessed their site and have <br /> determined that active remediation is warranted, will receive reimbursement With <br /> SWRCB policies towards reimbursement becoming more stringent, PHS-EHD <br /> recommends that you reevaluate your current proposal and include a deeper soil test <br /> as weil as notations of your future plans towards groundwater remediation <br /> PHS-EHD agrees that SVE testing is an acceptable procedure to investigate now , but <br /> cautions that by limiting your workplan to only addressing the sons to a maximum depth <br /> of 35 feet below ground surface, you may place yourself in a position that may not allow <br /> for approval of the Corrective Action Plan In order to better evaluate SVE as a full <br /> Iremediation process, PHS-EHD recommends that you modify this work plan and <br /> include a deeper SVE test in this phase as well as your recommendations for future <br /> Igroundwater remedial activities <br /> In all future reports please ensure that soil contamination data is recorded in mg/kg <br /> (ppm) units Continue to report groundwater data in ug/I (ppb) units Also, cross <br /> sections recently submitted had vertical depths fisted in "feet above mean sea level" In <br /> order to avoid any confusion, depths for well details and cross sections should be <br /> Ireferenced in "feet below ground surface" <br /> Please submit an addendum or revised work plan that addresses the concerns <br /> I mentioned above You may contact me at (209) 468-3454 should you have any <br /> questions or wish to discuss these matters. <br /> Donna Heran, RENS, Director <br /> Environmental Health Division <br /> Michael lnfurna, Senior jREHS MargaeLagon/o, <br /> ,n REHS <br />' LV 1"l S7i e IVii Lilg. at ion Unit IV %duvJ-1 V1.7V1 <br /> /MI/ <br /> ✓,c Environmental Audit Inc , - Wallid Kazi, R G , Placentia, 92670 <br /> c SWRCB - Steve Marquez, PO Box 944212, Sac, 94244-2120 <br />
