PHS/EHD informed ARCO that staff time to <br /> review the reports and make site inspections as necessary would be <br /> charged to ARCO according to the PHSIEHD hourly rate fee (currently <br /> $78/hour). Enclosed are the billing forms required to be completed and <br /> returned to PHSIEHD prior to approval of retaining the on site vapor and <br /> monitoring wells. It was agreed that all off site wells would be destroyed. <br /> In addition, to the above site specific discussions, it was also discussed that <br /> quarterly reports should be submitted to PHSIEHD prior to sampling of the wells <br /> in the following quarter and that samples are to be analyzed for five oxygenates <br /> using EPA method 8260 unless otherwise agreed to by PHSIEHD on a site <br /> specific basis. Enclosed is a letter from PHSIEHD to responsible parties <br /> directing this sample analysis. <br /> If you have any questions contact me at (209) 468-3449. <br /> Donna Heran, REHS, Director <br /> Environmental Health Division <br /> Margaret Lagorio, REHS, Supervisor <br /> Site Mitigation Unit <br /> c: CVRWQCB - Pat Anderson <br /> ARCO - Kyle Christie <br /> EMCON - Jay Johnson, Joel Coffman <br /> SECOR - Greg Barclay <br /> LOP files <br />
