SIMPL0T COMPANY, LATHROP <br /> PLANT, SAN JOA QUIN COUNTY, Case No. 3876 <br /> We have reviewed the Reconditioning Monitoring Well LP-2 report (Report), dated 1 December <br /> 2000, as prepared by Geomatrix Consultants, Inc. Based on our discussions in a meeting held at <br /> the Board on 18 December 2000 and the results of the reconditioning of the well, we concur with <br /> the continued use of LP-2 as a monitoring well. Also discussed in the meeting was the need to <br /> install additional monitoring wells in the shallow portion of the aquifer and a background <br /> monitoring well upgradient. <br /> J.R. Simplot should submit a work plan for the installation of additional shallow and background <br /> monitoring wells by 1 March 2001. Once the work plan has been approved, the Regional Board <br /> will revise Waste Discharge Requirements (WDRs) Order No. 97-229, Monitoring and <br /> Reporting Program (MRP). Revision of the MRP Order No. 97-229 requires the signature of the <br /> Executive Officer. <br /> If you have any questions please contact me at (916) 255-3078 or schwabk(a),rb5s.swrcb.ca.gov. <br /> Jam.
