I have also received the supporting documentation, dated 28 May. Recent <br /> soil tests found that onsite soil contained less nitrogen than anticipated,while the demolition work <br /> showed that approximately 80% of the facility had been paved. The groundwater has been sampled <br /> twice, and except for one reading, contained low concentrations of nitrates. <br /> i <br /> Based on the above, Board staff feel that the spills of feed product materials have probably not impacted j <br /> the groundwater. However, a "no further action"letter may not be issued until one more set of ' <br /> groundwater samples has been collected and analyzed. As we have discussed, samples are to be collected <br /> and analyzed in February 1998. The method of sampling and constituents analyzed shall be the same as <br /> for the previous groundwater monitoring events. If the February 1998 groundwater samples contain less <br /> than 10 mg/1 nitrate (as nitrogen), then staff will issue a closure letter. <br /> Staffwill not require any additional environmental remediation at this time. We look forward to <br /> receiving a report of the results of the February 1998 groundwater monitoring by 1 March 1998. <br /> If you have any questions, I can be reached at (916) 255-3078. <br /> WEN Y`^'11WYELS <br /> Agricultural Unit <br /> cc: Mr. John Rapp, Sierra Pacific Groundwater Consultants, El Dorado Hills <br /> Mr. Mike Iufurna, San Joaquin County Environmental Health, Stockton <br /> Ms. Charlene Wall, Port of Stockton, Stockton <br /> Mr. Jack Holm, Cargill, Stockton <br />�I <br /> i I17 Our mission is to preserve and enhance the quality of California's Hater resources,and <br /> j � Recycled Paper <br /> a ensure their proper allocation and efficient use for the benefit ofpresent and future generations. <br /> I <br />
