Tree and shrub clumps can be seen on Maps F-1 and F-2. The clumps are spaced about <br />100 to 200 feet apart along the shores of the expansion lakes. Area 1 has approximately <br />37 clumps. Area 2 has approximately 33 clumps. Area 3 has approximately 42 clumps. <br />2.) A sketch of the existing slopes and future slopes near the wash plant has been included. <br />Reclamation has been completed along the western edge of the pit. Slopes have been <br />filled along the river and eastern border. Additionally fill has been imported along the <br />remaining northern border. This fill still requires dozing to place it into final position. <br />The slopes around the office trailer will require backfilling as well as the remaining <br />slopes within the final mining area near the wash plant. The final mining area slopes will <br />be established by dozing the slopes down for a cut and fill balance. The required fill for <br />the other remaining 2630 ft of slopes will be 58,400 CYD. This will be supplied from <br />two stockpiles. The smaller stockpile lies between the final mining area of the Chambers <br />pit and the river. This stockpile contains 16,500 CYD of topsoil. The primary stockpile <br />lies on the Casey Concrete Permit. A letter signed by Casey Concrete and United is <br />included to verify ownership. This stockpile contains 51,000 CYD of silty <br />topsoil/overburden. From this, it can be seen that sufficient fill material for reclamation <br />is available on site. Additionally, the site will continue to accept imported fill material. <br />Any extra fill material will be used to further lessen the backfilled slopes. All above <br />calculations are based off the CAD model.. <br />3.) A letter stating the ownership of the fill material located on Casey Concrete's permit is <br />
