PERMIT/SERVICES <br /> 1830 West 38th Avenue <br /> Denver, CO 80217 <br /> MEETING SUMMAR Y, LEPRINO FOODS COMPANY, TRACY, SAN JOA Q UIN CO UNTY <br /> Thank you for the 30 July 2003 tour of the Tracy facility plant and subsequent meeting. We appreciate <br /> Leprino Food Company's interest and willingness to clean up the groundwater pollution from the diesel <br /> fuel spill. Enclosed is a summary of the meeting. <br /> As we discussed in the meeting,we concur that oxygenating the groundwater is an appropriate technique <br /> to accelerate biodegradation of the fuel remaining in the groundwater. However,we remain concerned <br /> that the extent of the downgradient migration of the pollution has never been defined. Also,we do not <br /> know where the nearest producing wells are located and whether they may be threatened by this <br /> pollution. Therefore, Leprino Foods needs to conduct a well survey to identify any wells within one-half <br /> mile of the site,prepare engineering calculations to determine how far the fuel may have migrated, and <br /> install a downgradient monitoring well in an appropriate location to document the stability of the plume. <br /> By 22 September 2003,please provide a work plan for the proposed groundwater oxygenation remedial <br /> measure and a schedule to conduct a well survey and install a downgradient monitoring well. If you <br /> have any questions, you-may contact me at (916) 255-3077 or at djuthg@rb5s.swrcb.ca.gov. <br /> GERALD J.
