Stockpiling of topsoil will be required for topsoil removal in the initial box cut, haul road, spoil <br />stockpile areas, sediment pond, shop area, and final pit/highwall reduction areas. Topsoil <br />stockpiles will either be located in areas that will not be disturbed by the ongoing mining <br />operation or in freshly backfilled areas prior to topsoiling. This will be necessary especially at <br />the end of mine life and on Morgan property prime farmland in order to insure that topsoil is <br />placed correctly for the post mine land use. Stockpiles will also be place in areas where the <br />stored topsoil will not be lost to wind erosion or surface runoff. When a topsoil stockpile is <br />placed, it will not be moved until soil is needed for distribution on graded areas, or is <br />consolidated into other existing stockpiles. Stockpile locations were also evaluated and selected <br />to minimize truck travel distance, to reduce equipment cost, and to increase efficiency. <br />Signs will serve as continuing reminders to personnel that stockpile areas are to be preserved and <br />undisturbed. <br />Any topsoil stockpile which will remain in place less than 90 days will not be revegetated. The <br />surface of each pile will be left in a roughened condition to retard wind and water erosion. A <br />self-contained grader ditch or berm will be constructed around the perimeter of the stockpile to <br />prevent loss of the topsoil resource. <br />Any topsoil stockpile which will remain in place for 90 to 180 days will be stabilized by utilizing <br />an annual grain (barley, oats or wheat) cover crop. The seeding rate will be 70 pound per acre <br />broadcast. <br />Protection and maintenance of "long-term" topsoil stockpiles will begin when a stockpile is <br />temporarily or fully completed and no more additions or withdrawals of topsoil are to be made <br />within a 180 day time period. Topsoil stockpiles will be stabilized primarily by perennial plant <br />establishment. The seed mixture, and seeding rate for long-term topsoil stockpiles is described in <br />the Revegetation Plan, Section 2.05.4(2)(e). <br />Establishing vegetative cover will aid in overall stabilization and erosion control of stockpiles. <br />Vegetative cover will aid in reducing runoff and raindrop impact and will increase moisture <br />infiltration by maintaining the upper soil surfaces in a friable, non -crusted condition. Organic <br />matter, soil nitrogen, and microorganism activity will be maintained or enhanced by the seeding <br />of deep rooted species or species with fibrous root systems. <br />The topsoil storage breakdown can be seen in Table 2.05.4(2)(d)-2 below. The stockpile <br />locations are shown on Map 2.05.4-9. <br />July 2018 (TR -84) 2.05.4(2)(d)-8 <br />
