(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 drainageways and separated from mining operations. <br /> We estimate the topsoil pile located in Phase 6 will contain 3,400 cubic yards of topsoil. <br /> The topsoil pile to be located in the current mining area(please see the Pre-mine/Mine Plan <br /> Map for locations) will contain approximately 9,400 cubic yards of topsoil. These <br /> amounts, along with the under burden(clay loam) left in portions of Phases of 3, 4 and 5, <br /> should be adequate as a plant growth material for site reclamation. <br /> (4) Relocation of topsoil stockpiles: <br /> Topsoil stockpiles are located so they may not have to be moved during mining operations. <br /> (5) 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 exists on site to <br /> 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(P2O5)) be applied. A combination of mulch or other organic matter and a <br /> nutrient source such as well-cured feedlot or barnyard manure could be applied. The <br /> recommended application method is to apply at a rate of at least twenty(20)tons per acre, <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 /> 38 <br />
