Box 690757 <br /> Stockton, CA 95269 <br /> PRELIMINARY SITE CHARACTERIZATION WORK PLAN FOR FORMER KARLSON <br /> TRUCKING FACILITY, 9909 EAST WOODWARD AVENUE, MANTECA, SAN JOAQUIN <br /> COUNTY <br /> I have reviewed the 28 January 1999 Preliminary Site Characterization Work Plan for Former Karlson <br /> Trucking Facility. I hereby approve the installation and analysis of 30 soil gas survey points. Upon <br /> completion of this phase of work, please submit a short letter report containing the results of the soil gas <br /> samples and the proposed locations for the monitoring wells. The monitoring well placement needs to <br /> determine the lateral and vertical extent of the petroleum hydrocarbon contamination in the soil and <br /> groundwater. It is likely that more than one well will be needed to define the lateral and vertical extent <br /> of the metal constituents in the soil and groundwater near SB7. <br /> The work plan does not present a time frame to complete the site assessment. Therefore by 3 March <br /> 1999, provide a schedule to conduct the field work and to submit the short letter report. Please inform <br /> me at least 72 hours in advance of the field work so I may be present to observe procedures or take split <br /> samples. <br /> If you have any questions, you may call me at (916) 255-3076. <br /> KRISTEN ROCHA <br /> Site Cleanup Unit <br /> cc: Mr. Stephen M.
