State Req. III IIIIIIIIIIIIIIII sss • element toxicity problems (see Tab 6 -Geologic Information -Overburden Assessment). 4.06.3 IV. TOPSOIL HANDLING SCHEDULE Topsoil removal and replacement depths have been estimated for the life of mine by calculating an annual topsoil budget (see Tab 9-I, Section III). The topsoil salvage and redistribution operation will maximize take and put methods whenever feasible throughout the life of the permit. This technique is economically desirable and also maintains a high topsoil quality including direct transfer of viable seeds and roots, low compaction, better structure, increased aeration, and high nutrient status. Topsoil stockpiles will be located in areas where they will not be disturbed by ongoing mining operations and where the stored topsoil will not be lost to wind erosion or surface runoff. Also, stockpile locations will be evaluated to minimize scraper travel distance, to reduce equipment cost, and to increase • efficiency (see Exhibit 12-I, Operations Plan). Topsoil salvage and redistribution will generally be limited to late spring, summer, and fall periods when surface soils can be handled with minimal physical degradation. Increased topsoil stockpile storage may occasionally be necessary in late fall and early winter to maintain an adequate buffer between pits and non-disturbed soils during upcoming snow bound winter months. Spoil piles are expected to be graded and topsoiled within one (I) year (generally represents three spoil piles) after the initial disturbance (see Exhibit 13-2, Reclamation Plan). • 9-9
