The initial tailings impoundment storage area will <br />occupy a rectangular shaped area that will have the dimen- <br />sions 275 feet by 100 feet at its longest and widest points. <br />This size was determined after surveying the outline of the <br />tailings impoundment dam in the field, and deciding to take <br />advantage of the natural topography and ground conditions to <br />build a smaller but deeper tailings retention structure. <br />The tailings dam will extend 330 feet along its outer face <br />from the northeastern edge to the southwestern edge of the <br />structure. By reducing the initial length of the tailings <br />impoundment dam, the entire site will be well screened from <br />public view from County Road No. 52 by the existing growth <br />of mature pine and aspen trees. A revised Millsite and <br />Tailings Pond Reclamation Plan Map that will reflect this <br />change will be submitted to the Mined Land Reclamation <br />Division as soon as the site work has been completed. <br />Once the tailings dam construction earth work has been <br />completed, the following sequence of geomembrane liner <br />installation will be followed: <br />1. The water decantation line and any seepage <br />monitoring lines will be placed in position along the <br />bottom of the tailings pond prior~to preparing the <br />-1- <br />
