end Topsoil Stockpiles. Approximately 32.0 acre feet of suitable topsoil is stored at • <br />these locations (see lab 9, Attachment 9-1 and Table 19-3). No additional topsoil <br />stockpiles are contemplated; however, should the need arise to disturb additional areas, <br />soil would be either hauled to existing stockpiles or to new stockpiles following <br />approval. <br />All topsoil stockpiles will be clearly distinguished and identified by approved signs. <br />All personnel ere instructed [hat topsoil stockpiles ere not to be disturbed or <br />contaminated. The signs serve as continuing reminders to personnel that stockpile areas <br />are to be preserved and undisturbed. <br />The following procedures will be followed should the need arise to store additional topsoil <br />in stockpiles. Soil will be store in existing stockpiles or new sites depending upon <br />where the disturbance area is located. Topsoil stockpiles will be located in areas where <br />they will not be disturbed or contaminated by ongoing operations and where the stored <br />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. <br />Future stockpile locations will be evaluated and selected to minimize scraper travel • <br />distant e, to reduce equipment cost, and to increase efficiency. <br />A self-contained V-ditch or berm will be constructed around the perimeter of the proposed <br />stockpiles, when necessary, to prevent loss of the topsoil resource (see Sediment and <br />Pater ConiroL Facility Plan section of Tab 13 ). The berms, ditches, end sediment traps <br />will typically be used when stockpiles are Located on steep slopes, where vegetation <br />establishment is delayed, or where runoff from the pile is not routed through a sediment <br />pond. <br />Any topsoil stockpile which will remain in place less than 90 days will not be <br />revegeteted- The surface of each pile will be left in a roughened condition to retard wind <br />and water erosion. <br />Any topsoil stockpile which will remain in place 90 to 180 days will be stabilized by <br />utilizing en annual gre in (wheat or barley) cover crop. The seeding rate and method is <br />described in Tab 20, Revegeta[ion Plan, Seed Xixes and Planting Lists section. <br />Protection and maintenance of "tong-term" topsoil stockpiles will begin when a stockpile • <br />6 <br />
