November 17 2003. Advanced Geo Environmental Inc. submitted an Additional Assessment Work Plan the oblective of this investigation is to assess the amount of remaining contamination in soil and ground water beneath the site building; the scope of work includes the advancement of five (5) soil borings at thirty-degree angles under the building. Results of these boring have not been received will be submitted when received Current Status of Site: • The effort to clean site continues with diminutive returns • Present property value on this site has been reduced to less than $25,000.00 • Chapin Bros Inc. has a net operating loss of over $200,000.00 • Under ground Tank Funds expenditure approximately $600,000.00 Previous action taken requesting this site be considered for a low risk closure was denied. Comments from the San Joaquin County Environmental Health Dept. upon denying my request were simply "money was not an issue" in their consideration. August 10, 2004 ATC ENGINEERING COMPLETED AND SUBMITTED REQUEST FOR CLOSURE FOR CHAPIN BROS. INC. PROPERTY AT 1766 MT. DIABLO for the total cost of $10,419.96 This report discussed and recommended NO FURTHER ACTION REQUIRED. Criterion 3 Contaminants Remaining in the varidose zone cannot migrate in soil vapor or leach at concentration that would create groundwater to exceed water quality objectives. Criteria 4 There are no existing water wells, surface water of other receptors threatened by the remaining contaminants in soil or groundwater. Criteria 5 Pollutants remaining in groundwater do not create or threaten to create a risk to human health and safety, or to future beneficial use(s) of groundwater. PATTERN'S OF EXISTING AND FUTURE DEMANDS FOR USABLE WATER RESOURCES IN THE AREA MUST BE CONSIDERED IN DETERMINING WHAT PERIOD OF TIME IS REASONABLE TO REACH NON-DETECTABLE (OR BACKGROUND CONCENTRATIONS). Criteria 6 the plume is stable and sufficiently limited in lateral and vertical extent and contaminant concentration detected in groundwater show a decreasing trend with time. October 4, 2004 San Joaquin County Environmental Health Department (EHD) response contained general and specific response to ATC Engineering Closure Report. With specific response to the above mentioned criteria. Environmental Health Dept. comments were very critical. Environmental Health Dept notes that even with acceptable models that support either ceasing groundwater remediation or a site closure consideration, it is most likely a period of monitoring will be necessary to validate the models.
