Exhibit D <br /> Mining Plan <br /> a) The affected property will be an open-pit mine using surface mining techniques. Topsoil <br /> will be stripped to a depth of 6 to12 inches and will be used to construct berms on the <br /> outer edges of the affected property. Haul roads will be built to remove and stockpile <br /> construction materials. Pit slopes will be cut into benches or steps to aid stability of the <br /> pit wall and contain any slope failures. The slopes shall not exceed a 2:1 ratio while <br /> mining and 3:1 slope for final reclamation. Sand and gravel will be removed from the pit <br /> wall and floor via bulldozer, excavators and front-end loaders. Processing of sand and <br /> gravel includes primary and secondary crushing units (jaw, cone or impact crushers) and <br /> screening systems. The crushing and screening units are portable. Materials are loaded <br /> into the processing equipment and the finished construction products are stockpiled at the <br /> end of belts. Other process equipment on site may include; Wash Plant, Asphalt Plant <br /> and Concrete Batch Plant. <br /> b) Earthmoving will be accomplished with the use of Dozers, Excavators, Front-end <br /> Loaders, Haul Trucks and Conveyors. <br /> c) All mining will occur above the ground water level and the project will not impact or <br /> injure any existing water rights. Any water needed for the haul roads will be supplied by <br /> the operator. <br /> d) Size of areas to be worked at any one time is expected to be approximately fifteen acres. <br /> Stockpiling and additional plant processing (Batch Plant and/or Asphalt Plant) anticipated <br /> to be situated on another five acres. <br /> e) Upon mining startup, approximately two acres will be disturbed to establish a pit haul <br /> road and a material scale office location. These will remain in place for the life of the pit. <br /> Initial Pit topsoil stripping and stockpiling will occur on the West end of the Pit. <br /> Stockpiles will be shaped and seeded upon completion. Phase one will involve removing <br /> the first fifteen feet of the Pit over approximately fifteen acres. Pit walls will be <br /> maintained at a 2:1 slope and in an non reclaimed state. This phase is estimated to take <br /> five years. Phase two will remove the next fifteen feet of the Pit floor and will establish <br /> the West Pit wall at a 3:1 slope. This wall will be reclaimed once it has been established. <br /> North and South Pit walls will be established yearly and reclaimed as they are exposed. <br /> Phase two is projected to take four years. Phase three will again remove the top fifteen <br /> feet of the Pit floor over an area of approximately fifteen acres. Progression is again <br /> anticipated to occur West to East. Pit walls will again be maintained in a 2:1 state with <br /> no reclamation occurring. Phase three is expected to take four years. Phase four will <br /> remove the next fifteen feet of the Pit floor exposing more North & South Pit walls that <br /> will be established at a 3:1 slope and reclaimed yearly as progression allows. Phase four <br /> is anticipated to take three years. Phase five will remove all remaining reserves in the Pit <br /> with progression from West to East. The remaining North and South Pit walls and East <br /> D-1 <br />
