Box 239 <br /> Tracy, CA 95378 <br /> SECOND QUARTER GROUNDWATER MONITORING REPORT, TRIPLE E <br /> PRODUCE, TRACY, SAN JOAQUIN COUNTY <br /> We have reviewed the 20 July 2001 Groundwater Monitoring Report Second Quarter 2001 <br /> (QMR) submitted by Condor Earth Technologies, Inc. (Condor) for Triple E Produce (Triple E) <br /> at 8690 West Linne Road, Tracy(site). The QMR summarizes the second quarter groundwater <br /> monitoring activities conducted on 5 and 6 June 2001, which included the annual standard <br /> minerals sampling. In the QMR, Triple E requests rescinding Waste Discharge Requirements <br /> (WDR) Order No. 96-118, abandoning seven of the nine site monitoring wells, reducing <br /> sampling to annual events, and eliminating standard minerals analyses. <br /> We have the following comments on the QMR: <br /> 1. Table 3 of the QMR does not list what the diamond symbol represents. Triple E must list <br /> the definition for all symbols and abbreviations used. <br /> 2. Condor should produce Figure 9 of the report in color to differentiate between the five <br /> wells and provide dates on the x-axis to illustrate the trends over a given period of time. <br /> 3. In the transmittal letter for the QMR, Condor concludes, "Chloroform plume continues to <br /> diminish along predicted trends." Board staff does not agree with this conclusion. As <br /> presented in Figure 9 of the QMR, two of the five linear lines illustrated are on an upward <br /> trend. Therefore, Triple E needs to continue groundwater monitoring on a quarterly basis, <br /> for at least two more quarters. <br /> 4. The QMR recommends rescinding WDR Order No. 96-118. The current WDR is Order <br /> No. 99-123 adopted on 17 September 1999. Board staff does not agree that the <br /> chloroform "trends are all nearly flat or downward" and requires additional data before <br /> WDR Order No. 99-123 is rescinded. <br /> California Environmental Protection Agency <br /> 0 Recycled Paper <br /> The energy challenge facing California is real.

L-U1L11%11111V1V, <br /> groundwater samples should be collected prior to abandoning, if the third quarterly event <br /> has not already occurred. <br /> 6. The standard minerals analyses results exceeded background concentrations in several <br /> wells for several constituents. Furthermore, several of the results have higher <br /> concentrations than were reported during the 2000 sampling. Therefore, standard <br /> minerals analyses will continue on an annual basis. <br /> Triple E must continue quarterly monitoring for a minimum of two more quarters to evaluate <br /> trends of constituents of concern. Based on that additional data, Board staff will re-evaluate the <br /> monitoring frequency and determine whether WDR Order No. 99-123 should be rescinded. The <br /> third quarter groundwater monitoring report is due by 30 October 2001.
