J&L Market 0 2 11 January 2005 <br /> 8125 S. EI Dorado St. French Camp <br /> workplan would be submitted sometime in January 2005. Mr. Hafner added that,pending my <br /> approval of the well destruction workplan,the well abandonment would be scheduled soon <br /> afterwards. I suggested that ATC consider videoing the interior of the onsite supply well to meet <br /> SJCEHD permit requirements if the plans were not available. Shortly after my discussion with <br /> Mr. Hafner,I talked to Mike Infuma about Mr. Hafner's remarks and my suggestion. Mr. Infurna said <br /> that SJCEHD would expedite the well abandonment permit process for you, that ATC may submit a <br /> letter Scope Of Work describing the well abandonment as a substitute for a workplan with the <br /> completed permit application, that a video of the interior of the onsite supply well could be <br /> substituted for plans, and that SJCEHD had sent a letter to you that day requesting that application for <br /> the well abandonment permit be made by 31 January 2004. Due to its proximity to the highest <br /> concentration of 1,2-DCA in monitoring wells at your site, you are to sample and analyze water from <br /> the onsite supply well for all contaminants prior to abandonment. You are to submit the past due <br /> Report as soon as possible,but under no conditions later than 1 March 2005. The Report is to <br /> include a description of the onsite well abandonment,with the analytical results, and the Work Plan <br /> described below. <br /> 2. The WI Report does not show that the groundwater plume is defined laterally to the south and east <br /> under South El Dorado Street, nor does it show the vertical extent of contamination. The WI Report <br /> includes only one isoconcentration map of the Methyl tert-Butyl Ether(MtBE)plume, which is, <br /> smaller in lateral extent than the 1,2-DCA plume. Because the WI Report does not define the extent <br /> of contamination, the Order requires inclusion of a Work Plan,to investigate and define the vertical <br /> and lateral extent of contamination, in the overdue Report. As stated above, the past due Work Plan <br /> is due as soon as possible,but under no conditions later than 1 March 2005. <br /> All future reports and workplans are to follow the Tri-Regional Recommendations for Preliminary <br /> Investigation and Evaluation of Underground Storage Tank Sites and Appendix A (Guidance). Please <br /> refer to the Internet link under the header of this letter to download the Guidance. The.Guidance <br /> requires isoconcentration maps of each contaminant, as is relevant to the lateral extent of contamination, <br /> and geologic cross sections showing the vertical extent of contamination. <br /> Provided that you submit the required Report, Work Plan and electronic data submittals by <br /> 1 March 2005, Regional Board staff will not recommend additional enforcement actions, which would <br /> include the assessment of administrative civil liabilities pursuant to Water Code Section 13268, <br /> retroactive to the original Order due date of 15 September 2004. <br /> If you have any questions, please call me at(916) 464-4615. <br /> 47gin <br /> Barton, R.G. <br /> eering Geologist <br /> cc: Mr. Mark Owens,UST Cleanup Fund, SWRCB, Sacramento <br /> Mr. Michael Infurna, San Joaquin County Environmental Health Department, Stockton <br /> Mr. Todd Hafner, ATC Associates, Inc., Modesto <br />
