constructed if conditions require. Access Roads A anal B will <br />be locked during non-working hours. Additional ha 1 roads <br />within the affected lands may be constructed during the <br />permit life. <br />Initially, the processing plant and equipment gill be <br />located immediately south of Access Road B in an already <br />disturbed area. Two acres of old tailings will be g aded to <br />provide a level operations surface. An already existing <br />impoundment adjacent to Plant A will be upgraded to hold <br />process wastewaters. <br />Due to the historical mining in the North Centra Phase, <br />very little top soil remains. Assuming an average f one- <br />foot thickness of topsoil, only an estimated 11,3 0 cubic <br />yards of topsoil exists in the portyons of the North Central <br />Phase to be mined. (See Plate 3)! This remaining topsoil <br />will be sequentially stripped from those areas as t ey are <br />mined, and stockpiled for later use. A dozer will ush any <br />surface boulders oEE of the soil bearing areas. Then a <br />front-end loader can load the topsoil into trucks to be <br />transported and stored in the topsoil storage area m rked on <br />Exhibit C, Plate 4. Vegetation will be stockpiled al ng with <br />the soil. Since the stockpiled topsoil will be u ed the <br />following year, revegetation of the stockpile is not <br />planned. The stockpile will be approximately 300 feet x <br />• 100 feet x 10 feet high. Later topsoil stockpiles B and C <br />will each be 400 feet x 300 feet x 10 Eeet high. <br />No topsoil exists in the area to be utilized in initial <br />phases for the processing plant, spoils areas, and arking <br />and roads. <br />Topsoil covers the areas to be mined in later phase This <br />topsoil will be stripped, stockpiled and used as in icated <br />below. <br />Mining Operations <br />The mining methods employed in each stage will be he same <br />for the entire mining operation. Panhandle plans to operate <br />24 hours a day, seven days a week from mid-April to late <br />November, as weather permits. <br />(1) Mining operations will commence during the fi: <br />of operation and will continue for an estimated t <br />years over the life of the mine. Buffer zones iodic <br />Exhibit C, Plate 4 will remain unmined during the <br />term, but portions may be utilized for temporary p: <br />of spoil and topsoil stockpiles.
