GeoAudit has also not received approval of the FRP from <br /> the Board. <br /> The Final Remedial Plan submitted to the RWQCB on July 31 , 1993 and <br /> the addendum submitted on October 5, 1993 , proposed a phased <br /> approach to the remediation of the site. Remediation of soil <br /> contamination would be undertaken in the first phase by introducing <br /> hydrocarbon-consuming bacteria into vadose-zone wells (including <br /> monitoring wells that do not extend to the present groundwater <br /> table) . In the second phase remediation, groundwater remediation <br /> would be initiated by introducing these bacteria into some of the <br /> groundwater monitoring wells. <br /> We are in a position to proceed with the first phase of <br /> inoculation. However, we are nearing the November 15 deadline for <br /> the initial inoculation, and it is now apparent that we will be <br /> unable to inoculate as scheduled due to information concerning <br /> WDR' s, received on November 10 1993 , from Ms. Patricia Leary. <br /> It was initially believed that the first phase of remediation <br /> (soil) could proceed on schedule without WDR's or a waiver. <br /> However, we have now been informed that a waiver (or WDR' s) will be <br /> required for the first phase of remediation, as well as the second <br /> phase (water) . <br /> • It is the intention of GeoAudit and the Geweke's to fully comply <br /> with the directives in the Cleanup & Abatement Order; however, <br /> because of additional questions and concerns of the Board, approval <br /> of the FRP has been delayed. Therefore we would like to request an <br /> 1 <br /> Full Spectrum Environmental Services• Hydrogeology <br />
