July 22, 2008 Advanced Geological Engineering prepared a finding and scope of work. <br /> Among other comments Significant or detectable soil vapor contamination was not <br /> present during DPE test, thus residual soil vapor should not be significant. Also based <br /> on analytical ground water sample data collected prior and during the pilot test the <br /> hydrocarbons concentration of the wells and hydrocarbons concentration in extracted <br /> ground water did not fluctuate Advanced Geological Engineering recommends: <br /> continued operation of the ground water extraction system, with an augmented capture <br /> regime at selected locations. Verbal discussion with the City of Stockton sewerage <br /> system concerning the huge bill of the city service and the inability of Advanced <br /> Geological Engineering to pay this amount and desire to suspend. This prompted a <br /> letter from Environmental Health Dept. <br /> November 21, 2008 Letter received from State Water Resources Control Board <br /> ADVISING THEIR INABILITY TO PAY BILLS FOR THE UST Executive officer Pamela <br /> C. Creedon <br /> November 25, 2008 San Joaquin Environmental Health Dept. letter advising the GWW <br /> system must be kept in operation until they approve cessation. The letter gave us 14- <br /> days to comply on a procedure we already was in compliance <br /> November 25 2008. Advanced Geological Engineering submitted a report Subject; <br /> Suspension of Work and Operations for the Site. Advanced Geological Engineering <br /> supports site closure for this facility <br /> January 6, 2008. Advanced Geological Engineering reports Ground Water 4th Quarter <br /> 2008 stating Analytical data shows the ground water is being remediated. The <br /> DECLINE in concentrations at monitoring well MW-4 is the next step to evaluating site <br /> remediation success. <br /> If necessary. Professionally stating, Any NEW remediation technology applied to the <br /> site would likely not be justified — cost wise —the current system is working well to treat <br /> the site. However, a new Extraction point at well MW-4 IS justified, or Temporary batch <br /> extraction (Vacuum ground water extraction) from well MW-4 would be equivalent. <br /> January 7, 2009 Chapin Bros Inc. contacted State Water Resource Control Board, Mr. <br /> Kirk Larson requesting consideration to again reviewing our request for site closure <br /> YEAR (5) REVIEW. <br /> January 15th, 2009 Advanced Geological Environmental submitted Batch Ground Water <br /> Extraction —Work Plan Addendum Ground water extraction remediation of monitoring <br /> well MW4. <br /> January 21St 2009 Chapin Bros Inc. response to State Water Resource Control Board <br /> letter dated November 21, 2008 advising Chapin Bros that the underground state fund <br /> cannot pay their bills. Thus, we found it impossible to comply with the clean-up and <br /> abatement order. <br />
