MINING PLAN EXHIBIT D <br />setback area around the mine. As 20 to 25 feet of gravel and <br />caliche is removed from over the bedrock, a fairly level depres- <br />sion will be created in the pasture. The green area shown on the <br />Reclamation Plan Map is the area that will be disturbed over the <br />life of the mine. <br />Growth medium was stripped from the existing mined area and <br />stockpiled along the eastern side of the old mine area. As <br />mining begins in the new area the salvaged topsoil will be <br />stockpiled on the setbacks, or floor and/or will be replaced as <br />mining progresses so it is not double handled. Processing will <br />remain in the existing permit area on the northwest side of the <br />mine until mining reaches the east side. From then on the <br />processing plant will be setup near the working face to reduce <br />the haul distance from the face to the processing plant. The <br />Plant Site location shown on MAP EXHisiTC-1 is not it's permanent <br />location as it will move with the face. <br />We will maintain a 15-foot setback from the permit boundary <br />so there is room to get around the tops of the slope for mainte- <br />nance, grading and shaping. Being a dry operation, no ground <br />water will be encountered because depth to water in this area is <br />195 feet or more. Reclamation will run concurrent with mining to <br />reduce the amount of disturbance at any one time. Review of MAP <br />EXHisiTC-1 shows how we expect the site to look when mining is <br />approximately 45% complete. Note, the floor of the excavated <br />area is flat and the slopes into the mined area are 3h to lv <br />where mining is complete around the exterior. The eastern side <br />of the mine face is temporarily sloped while the west side in <br />being worked near vertical. <br />By using a portion of the existing mined area as the start- <br />ing point we reduce the amount of time it will take to open the <br />facility and the amount of area that will be disturbed initially. <br />As mining begins on the new area, a portion will be striped of <br />any topsoil/overburden. The topsoil will be stockpiled on the <br />excavated area so it will be available for reclamation. The <br />topsoil stockpiled will be used when reclamation begins for <br />resoiling slopes and other areas where soil will be needed to <br />establish vegetation. <br />As mining approaches the outer perimeter of the mine the <br />first step will be to locate the 15-foot setback that defines the <br />digline. From this line a second line will be staked 60 feet <br />away to establish the toe of the 3:1 slope (20' x 3). This 60- <br />foot wide area is where vertical mining would end so final slopes <br />10
