' Environmental <br /> Mr Harlin Knoll Resources <br /> 27 January 2000 Management <br /> Page 6 <br />' We believe that no further remediation and/or investigation activities <br /> are required at the site based on the following <br /> • Significant reductions in chemical concentrations at each former UST <br /> site have been observed since the investigation/remediation project <br />' was initiated, <br /> O Relatively low concentrations of detected compounds remain in <br /> groundwater at each UST site, and <br />' ® The areal extent of the chemicals in groundwater at each UST site is <br /> limited <br />' Based on this information we believe that the County should support a <br /> finding that no further remediation and/or investigation activities are <br /> required, with the understanding that groundwater concentrations and <br /> the areal extent of those concentrations will continue to decrease over <br /> time <br /> Heinz would like to schedule a meeting with the County and the <br /> RWQCB to discuss the results of the post-ORC injection groundwater <br />' sampling program and the future status of the site We understand that <br /> should no further action be granted, a closure report for the site will be <br />' required <br /> If you have any questions regarding the sampling results, please call me <br />' at (925) 946-0455 <br /> Sincerely, <br /> 2Matthew L Brandy <br /> Project Manager <br /> ' MLB/inlb/3374 60 <br /> cc Mr Scott Krall, Heinz -Pittsburgh, PA <br /> Mr Marty Hartzel, CVRWCB <br /> Ms Margaret Lagorio, SJCEHD <br /> Mr James F Devenport, The Cranbrook Group , <br />
