Tibbits Brook, Rice Lake and a large wetland complex lie about <br />1,000 feet northwest of the site on the west side of the <br />abandoned railroad track. <br /> <br />Figure 2 is a U.S.G.S. Quad map excerpt that illustrates the site <br />setting. <br /> <br />c. Estimate of Quantity of Material to be Mined: <br /> <br />The estimated quantity of material to mined is around <br />7,000,000 cy. This includes topsoil and overburden. The <br />number is based on U.S.G.S. Quadrangle 10 foot contours and <br />the proposed excavation grades. Depending upon the <br />consistency of material with depth and the occurrence of <br />unsuitable material, the actual amount to be mined may be less. <br /> <br />d. Depth of Water Table: <br /> <br />The depth of the water table was identified during the ElS <br />process. The water table ranges from about 957 in the northern <br />portion of the site to about 945 in the southeast corner of the <br />site. A ground water divide, running approximately northeast- <br />southwest runs through the site. Figure 3 illustrates the depth <br />of the ground water and ground water flow directions beneath <br />the site. <br /> <br />Mining under this permit will occur to the grades illustrated on <br />the Excavation Plan, Sheet 1 of 2. These grades have been <br />developed to stay a minimum of five feet above the water table. <br />Mining into the ground water may be requested in the future. <br /> <br />e. Average thickness of overburden <br /> <br />The average thickness of overburden is estimated to range <br />between 0 and 5 feet. The overburden is a sandy loam. <br /> <br />8.) Plan of Operation: <br /> <br />The plan of operation is to extract and process sand and gravel on the <br />site. Processing will consist of crushing, screening, stockpiling, and <br />production of hot mix asphalt. During the initial stages of operation, <br /> <br />5 <br /> <br /> <br />
