• 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, noncrusted condition. Organic <br />matter, soil nitrogen, and microorganism activity will be maintained or enhanced by the seeding of <br />deep rooted species or species with fibrous root systems. <br />As of the Mid Term Review of 2006, the following topsoil stockpiles and quantities exist on site. All <br />of these locations are shown on Map 2.05.3(3)-1 Surface Hydrology. <br />Table 2.05.4(2)(d) -Topsoil Stockpile Inventory <br />• <br />Topsoil Pile <br />Name Type of <br />To soil Volume (CY) Location <br />A MIXED 4,000 SE CORNER OF PERMIT <br />B LIFT 2 77,368 SE CORNER OF PERMIT <br />C LIFT 1 12,890 SE CORNER OF PERMIT <br />D MIXED 4,094 SE CORNER OF PERMIT <br />E MIXED 10,483 EAST OF PERIMETER ROAD EAST <br />CENTRAL PART OF PERMIT <br />F&G DNA 0 ALREADY USED IN RECLAMATION <br />H,I,J MIXED 23,810 NORTHEAST OF PERIMETER ROAD <br />IN NE PART OF PERMIT <br />K MIXED 3,100 IMMEDIATELY SOUTH OF POND 007 <br />TOTALS 135,745 <br />• (Revised 24 AUG O6) 2.05.4(2)(d)-15 <br />
