July 18, 2002 <br /> <br />Mr. Steve Rohlf <br />City of Elk River <br />13065 Orono Parkway <br />Box 490 <br />Elk River, MN 55330 <br /> <br />RE: Elk River Landfill - P17C Groundwater Remediation Project <br /> <br />Dear Steve: <br /> <br />This letter is sent to respond to the Waste Management (WM) request for cost sharing for expenses <br />related to the groundwater remediation project in the P17C area of the landfill. The work being <br />undertaken by WM is a preemptive voluntary effort to reduce the VOC contaminants inside the landfill site <br />before they migrate to the property boundaries. Documentation of the project scope and costs are <br />presented in correspondence from Geomatrix Consultants, Inc to Mr. Terry Johnson, WM's project <br />Hydrogeologist, dated April 12, 2002. <br /> <br />We have worked with WM and their consultants to generate a remedial approach that will involve insitu <br />aerobic treatment of contaminants where they are observed in their highest concentration on the site. <br />The groundwater remediation plan has also been designed to include a wide degree of flexibility to enable <br />hydraulic control, hydraulic capture and in-situ nutrient enhancement if the concentration of contaminants <br />is not sufficiently reduced with oxygen addition only. <br /> <br />From 1997 to date, WM has spent approximately $135,000 for the work completed in the PC17C area. <br />Approximately $100,000 of this amount has been spent on investigating the horizontal and vertical extent <br />of the contamination in the vicinity of the P17C area. Approximately $35,000 has been spent on the first <br />phase of treatment point installation for the remediation. Two additional phases of the remediation project <br />would be conducted over the next several years at an estimated cost of an additional $135,000. <br /> <br />In the initial conversations with WM concerning potential cost sharing, the City of Elk River indicated that <br />it may be willing to provide 50 percent cost sharing associated with the actual remediation cost, up to a <br />$70,000 total contribution. Qualified costs to date are $35,000. If the City elects to take this course of <br />action, I would recommend that the City's cost sharing contribution for the first phase of the remediation <br /> <br />Please contact me if you have additional questions or comments regarding this matter.
