Gene Gabbard Inc. - 3 - 12 October 2004 <br /> 640 El Dorado Street, Stockton, San Joaquin County <br /> groundwater as a lost resource. Also,there may be other, innovative technologies available in the future <br /> to address problems of low quality groundwater resources. <br /> John stated that they were looking into active skimmer to replace the current passive skimmer for free <br /> product in the source are, possibly a belt skimmer that works in 2"diameter well. <br /> • Site closure criteria. <br /> Pat and John asked for closure criteria for site. I suggested they visit our website to download guidance <br /> documents for USTs. John said that our guidance is nebulous. I offered to work with John afterwards to <br /> clarify any specific questions on the guidance documents, but no questions were asked later. Pat said that <br /> every site gets different consideration for closure. I said that there is not a"One size fits all' approach to <br /> site closure, which is due to the complexities and uniqueness of each site (geology,hydrogeology), and <br /> that professional judgment is necessary to assess the progress made towards each site closure. The basic <br /> approach is in the Appendix A -Reports, Tri-Regional Board Staff Recommendation for Preliminary <br /> Investigations and Evaluation of Underground Storage Tank Sites, April 2004, which states the beneficial <br /> uses of groundwater must be protected. Pat said that they agree that each site is different. <br /> The meeting ended at 1040. John stayed behind a few minutes to discuss various investigative and <br /> remedial technologies with Nuel, Lori and myself. <br /> California Environmental Protection Agency <br /> 0 Recycled Paper <br />
