Additionally,the site map, referred to as Figure 1,depicts the location of three wells off-site <br /> but fails to show the on-site monitoring well location. Either submit an accurate site map that <br /> correctly depicts the locations of two off-site wells and one on-site well,or submit a corrected text <br /> that refers only to three off-site wells. <br /> On November 2,2000 PHS-EHD directed you to submit a work plan"to delineate the [methyl <br /> tertiary butyl ether] (MtBE) groundwater plume" by January 5,2001. That same correspondence <br /> stated that MtBE has impacted all monitoring wells associated with this site. When the work plan <br /> was not submitted by the January 5, 2001 deadline,PHS-EHD issued a"14-day" letter on January 9, <br /> 2001. Bolded print included in this � was �rected that"...a uwk submitted within 14 days ofn to the date lateral <br /> that <br /> wniral extern of the pd7deumgrapjd P <br /> correspondence (i.e.,January 23,2001). <br /> The work plan submitted on January 16,2001 met the new deadline,but failed to meet the <br /> requirement to define the lateral and vertical extent of the MtBE plume. Instead,the work plan <br /> focused only on the lateral extent of the plume northeast of the site. It appears that you may have <br /> misunderstood PHS-EHD's intentions by not submitting a work plan that would include an <br /> investigation to define the lateral and vertical extent of MtBE groundwater contamination at this <br /> site. <br /> As a result of recent phone conversations between GTI representative Doug Lee and Mike Infurna <br /> of P1S-EHD,it is our understanding that long-range plans exist for this site. To remove any <br /> misunderstanding that may exist and to better address these potential long-range plans,PHS-EHD <br /> offers the following options for your consideration. <br /> A Division of San Joaquin County Health Care Services <br />
