CAMBRIA <br /> On June 20, 2001, a permanent GWE and treatment system, began removing groundwater, <br /> treating it, and discharging it directly into the sewer system The GWE system has operated <br /> intermittently since continuous discharge began GWE system analytical data and GWE system <br /> mass removal data are presented in Table 2 and Table 3, respectively MTBE concentrations and <br /> mass removal from well RW-lA are depicted in Figure 3 Certified analytical reports for <br /> samples collected from the GWE system are presented as Appendix B Volume and mass <br /> removal data for vacuum truck operations and the permanent GWE system are summarized in the <br /> table below <br /> Mass TPHg Mass MTBE Volume <br /> Removed(pounds) Removed(pounds) Groundwater <br /> Removed (gallons) <br /> Vacuum Truck 397 671 622,649 <br /> Operations <br /> Permanent GWE 584 730 2,062,420 <br /> System <br /> Total(GWE) 1981 1401 2,685,069 <br /> According to the City of Stockton's October 10, 2003 letter, discharge limits for fuel oxygenates <br /> at non-detect levels now apply to our GWE system effluent Cambria received this letter on <br /> October 14, 2003, and immediately shut the GWE system down, pending an evaluation of <br /> appropriate design changes to our treatment system in order to address these new discharge <br /> limitations <br /> ANTICIPATED FIRST QUARTER 2004 ACTIVITIES <br /> Blaine will gauge and sample the site wells according to the established sampling schedule and <br /> tabulate the data Cambria will prepare a groundwater monitoring report <br /> Due to the limitations of available groundwater treatment technology and the non-detect <br /> discharge limitations issued by the City of Stockton, we will no longer be able to operate the <br /> site's GWE system and discharge to the sanitary sewer In an attempt to continue groundwater <br /> cleanup at the site, Cambria will apply for an NPDES permit Cambria will also pursue any <br /> necessary GWE systems alterations necessary for operating the system under an NPDES permit <br /> Cambria will prepare a work plan proposing the installation of an additional groundwater <br /> monitoring well, which will be located between wells MW-2 and MW-8 A well placed in this <br /> 0783 2 <br />
