1. TOPSOIL REPLACEMENT <br /> <br />As described in the Mining Plan, approximately 86,270 cy of soil is available from two stockpiles as <br />shown on Map C-2. Much additional soil is available from ongoing stripping as the site is mined and <br />reclaimed. As shown in the soils section, soils exist on the entire site to 1' depth and deeper, but <br />there is no need to sepazate and restore the vast majority of this soil since the site will be replacing <br />approximately 94 acres of land with lakes. For this reason, some soil will be mixed with overburden <br />during the stripping process. In all reclaimed land areas, a minimum of 8" of topsoil will be replaced <br />although all of these azeas aze designated to be returned to industrial use except for the lake fringes, <br />which aze wetlands. <br />The amount of total area to be topsoiled is wetlands (6.39 acres), sloped azeas (7.6 acres) and indus- <br />trial pads (69.77 acres) = 83.76 acres. using a replacement thickness of 8 inches, this yields a total <br />topsoil volume needed of 90,088 cy. Since 86,270 is available from stockpiling, only 3800 cy is <br />needed from ongoing stripping. <br />• The topsoil will be placed on fmished slopes as they are made, so that the only amount needed to be <br />replaced at the end of the mining process is 20.1 acres from the Area 5 pad and the facilities azea, <br />therefore, the total topsoil to be moved at the end of mining is 21,618 cy. This represents the amount <br />for worst case reclamation costs. <br />3. REVEGETATION <br />The industrial pads and slope areas of 77.37 acres will be harrowed and drill seeded with a mix con- <br />sisting of the following in order to control erosion: <br />Alkali Sacaton @ 15.0 lbs/acre <br />Inland Saltgrass @ 15.0 lbs/acre <br /> <br />15 Road Pit 10/02 26 <br />
