(3) Storage,location,configuration of topsoil stockpiles for control of erosion <br /> and protection from mining operations: <br /> Control of topsoil stockpiles from erosion and protection from mining operations is <br /> addressed in Section 3. 1 .9(1). The Pre-mine. Mine Plan map shows the location of topsoil <br /> stockpiles. away from drainage ways and separated to the extent possible from mining <br /> operations. <br /> We estimate the topsoil piles to be located in the current mining area(please see the Pre- <br /> mine/Mine Plan Map for locations), will contain approximately 160,000 cubic yards of <br /> topsoil. This amount should be adequate as a plant growth material for site reclamation in <br /> order to replace 3 to 6 inches. The existing operation has topsoil stockpiled along the <br /> boundary)between the county road and the existing pile to reclaim the existing 112 mining <br /> operation. <br /> (4) Relocation of topsoil stockpiles: <br /> Topsoil stockpiles are located so they should not have to be moved during mining <br /> operations. <br /> (S) Stabilization measures of replaced topsoil on re-graded areas: <br /> The Operator will take measures appropriate to the subgrade where topsoil is being <br /> replaced. Such measures may include roughening the surface in order to gain a mechanical <br /> bond between the subgrade and the replaced topsoil. Where the subgrade is of acceptable <br /> quality, it may include disc plowing the topsoil and subgrade together. a practice typically <br /> used by commercial landscapers. <br /> (6) Segregation of other materials for use as topsoil: <br /> No replacement or substitute materials will be needed. Sufficient topsoil resources exist on <br /> site to complete reclamation requirements. <br /> (7) Replacement criteria and soil amendments: <br /> The Operator will replace topsoil in as even a manner as equipment allows. Soil <br /> amendments will be applied based on soil tests. Typically, it is recommend that if soil tests <br /> are not preformed,forty (40)pounds per acre of each of the major nutrients(nitrogen and <br /> phosphoric acid(P205))be applied. A combination of mulch or other organic matter and a <br /> nutrient source such as well-curied feedlot or barnyard manure could be applied. The <br /> recommended application method is to apply at a rate ofat least twenty(20)tons peracre, <br /> evenly spread. The manure should contain at least 60% (by weight) large chunks, five <br /> inches or more in diameter. (Granular or powdery manure will not meet specifications.) <br />
