• 2.05.3 <br />C~ <br />• <br />PR-06 <br />f/ ~y,2oVED <br />1~f5/O Z, <br />The material that will cover the geotextile fabric is the subsoil which is <br />categorized in Section 2.05.9 as clay and clay loam. Permeability of the clay <br />and clay loam material is low, therefore leachate from the fill should not <br />cause any significant contamination of the topsoil below the geotextile fabric. <br />A few inches to topsoil along with the vegetation will be salvaged and placed <br />in the topsoil stockpile prior to the placement of the geotextile fabric. Thus, <br />the totoal quantity of soil to be handled and stored will be minimized, the <br />intact soil horizons would be minimally impacted, and upon final reclamation <br />the small quantity of replaced topsoil will provide a source for restoration of <br />mychorrizae and other soil microbes to the reclaimed area. <br />When the coverfill stockpile is reclaimed, a motor grader or other appropriate <br />equipment will be utilized to remove the coverfill from the geotextile fabric. <br />The geotextile fabric is designed for long term separation of materials, <br />therefore its strength properties should be intact after decades of burial. <br />Once the geotextile fabric is removed, the topsoil will be ripped to relieve <br />compaction, the few inches of topsoil replaced and the area will be <br />revegetated. <br />The operator will report to the DMG the volume of topsoil actually salvaged <br />and placed into topsoil stockpile F upon completion of the topsoil salvaging <br />operations. <br />Topsoil stockpiles were and will be so constructed to reduce erosion of the <br />stockpiles by either wind or water. The topsoil stockpiles are located on <br />stable surfaces where they will not be disturbed by the mining operation. <br />Topsoil stockpiles that are to remain in place for more than ninety days will <br />be seeded as soon as practical and berms will be constructed around the <br />base of stockpiles where necessary to prevent loss of topsoil material from <br />the stockpiles. <br />The operator initially salvaged approximately 87,600 cubic yards of topsoil <br />during the construction of the haul road and portal bench. The topsoil was <br />located in three topsoil stockpiles as follows: <br /> Pile A Pile B Pile C <br />Quantit CY 83,300 2,800 1,500 <br />2.05 - 37 - 11/01 <br />
