As we discussed, there have been many <br /> significant changes recently to the pay structure of the State UST Cleanup Fund. <br /> Reimbursements are not expected for any work on this site (`B" status) for up to 18 months. <br /> Neither the Responsible Party, nor Clearwater Group (the Consultant) can cant' these costs for <br /> 18 months of the ongoing remediation, operations and maintenance, and quarterly groundwater <br /> monitoring tasks that are currently performed at this site. Until other sources of funding are <br /> sought and secured to cover the period that claim reimbursements are being delayed, we are <br /> writing to suggest options for the interim. <br /> Specifically, as we discussed, we are seeking your approval that a six-month suspension in site <br /> monitoring and remediation system operationsandmaintenance activities be grantedsothat-the <br /> additional sources of funding can be located and secured to continue with the cleanup process at <br /> this site. This suspension would begin today and end after the first week of October, 2009. <br /> During this six month timeframe, one reduced scope Operations and Maintenance event (with <br /> isoc tool removal) would take place and no second or third quarter 2009 monitoring events <br /> would take place. The work scope of this Operations and Maintenance event would be to simply <br /> close the oxygen tanks, and test and remove the oxygen diffuser (6066 1) units. It is <br /> recommended that after this six month period, sampling occur, to establish whether any rebound <br /> in levels of contamination are observed After this six-month period, one annual monitoring <br /> event would occur in late 2009 to determine whether contaminant concentration levels are stable, <br /> decreasing, or increasing. <br /> If concentrations are increasing, the conclusion will be made that a source remains in the soil and <br /> a work plan for source-area remediation will be submitted. If concentrations continue to decrease <br /> in the absence of enhanced bioremediation, the iSOC units will be returned to operation to <br /> continue to accelerate the decrease in contaminant concentrations to levels acceptable to the <br /> Board for case closure. <br /> 229 Tewksbury Avenue ♦ Point Richmond, Californig94801 ♦ Telephone: 510-307-9943 ♦ Fax: 510-232-2823 <br />
