The Board's <br />analysis, however. also included a reviw of subsurface conditions based on an <br />analysis of well logs at the tlinnesota Geological Survey. <br /> <br />r <br /> <br />I I <br /> <br />These well logs for the Ramsey area indicate that below the layer of coarse <br />material found at the surface there is a layer of clay or clay/sand/gravel mix- <br />ture.~ ~The lower portion of the ylacial material may contain a single clayey unit <br />or multiple clayey units separated by sand or gravel. Existing records indicate <br />,that bedrock aquifers are used for water supply in this area with few exceptions. <br />Overall, the aquifers are separated from the surface by one or more clayey units. <br />(See attached report.) , ' <br /> <br />It should be noted, however. that soil and subsurface conditiqns are not considered <br />a major factor in siting treatment facilities. Unlike land,disposal facilities <br />(such as exist in this area), a treatment facility is an above-ground, industrial <br />operation. <br /> <br />Both the Minnesota Pollution Control Ag'ency (MPCA) and the Minnesota Geological <br />Survey (MGS) have advised the Waste Management Board that soil conditions are <br />not critiCal for hazardous waste processing facilities due to the requirements <br />for full containment of materials on site (through design of the building and___ <br />operation). Jhe MPCA stated that while heavy textured subsoils are preferred <br />due to the impermeabl e nature of such soil s, other soil s shoul d not be auto- <br />matically considered unsuitable. The MGS noted that contact between the soil <br />and hazardous materials'would occur only if and when the man-made containment <br />structure failed and this contact would only exist until clean-up procedures <br />were compl.ete. ' <br /> <br />The DNR Division of Waters <br />public waters are located. <br />protected waters have been <br /> <br />has reviewed. all proposed areas and indicated where <br />The DNR'noted seven protected water areas and all <br />removed from the proposed area (see map). <br /> <br />BO;.RD ""EMSERS DIS1RIC1'.
