I~ Plan for Soil Storage - Kerr Mine Area Although ideally soil removed from one area would be immediately redistributed on an adjacent area being reclaimed, at the Kerr Mine Area significant quantities of topsoil and subsoil, of necessity, will be stockpiled. The estimated quantities of topsoil and subsoil to be stockpiled are found in Table 69, Soil Removal and Storage Plan. In this regard, all of the proposed stockpile areas identified on Map 31a, Kerr Mine Area Soil Removal and Storage, result from situations where contemporaneous redistribution is not possible either because redistribution areas are not available at the time of soil removal or because more soil is being removed than is needed for contemporaneous redistribution. Each proposed soil storage area identified on Map No. 31a, Kerr Mine Area Soil Removal and Storage is divided into distinct topsoil and subsoil stockpiles with one exception. (See Section 816.22-816.23.) Topsoil and subsoil stockpiles are specifically sited to avoid erosion from wind and water, and additional compaction or contamination. As can be seen from the topsoil storage maps, all present and major proposed stockpiles are located within stable areas outside of drainage bottoms. Two small stockpiles will be located adjacent to Williams and Bush Draws, but will be placed outside the stream buffer zones. Refer to Map 31a, Kerr Mine Area Soil Removal and Storage. In addition to the physical protection afforded through appropriate location, Kerr Coal proposes to implement additional measures to prevent erosion once the stockpiles are in place. Specifically, for stockpiles scheduled to be in place for only one growing season, a rapidly growing cereal grain species such as oats or rye will be 780-66 as
