The <br /> Proposed Monitoring states Lincoln Trust will change the 15 October 1999 Periodic Groundwater <br /> Monitoring Plan, Lincoln Center, Stockton, California, as follows: reduce sampling frequency from <br /> • quarterly to tri-annual sampling,reduce reporting frequency from quarterly to semi-annual, discontinue <br /> sampling in two monitoring wells, and reduce the number of samples from 210 to 99 a year. <br /> The 8 January 2001 Proposed Revisions to Periodic Groundwater and NPDES Monitoring and <br /> Reporting Activities changes sampling from quarterly to tri-annual and reduces the number of samples <br /> from 210 to 117 a year. Based on Board staff s 19 July 2001 letter, Lincoln Trust now proposes only 99 <br /> samples a year in the Proposed Monitoring. The Proposed Monitoring does not allow for sufficient <br /> monitoring of the plume extent. In the attached draft Monitoring and Reporting Program (MRP),we <br /> have made seven changes to the Proposed Monitoring to provide sufficient plume coverage. <br /> By 8 November 2001,please provide comments on the draft MRP.
