Soil P.e cove ry Documentation <br />• was documented b <br />dail <br />Soil recove observation by the gx ading foreman and pit <br /> y <br />ry <br />y <br /> supervisor. Thrs quality control informat ion is used to verify soil salvage estimates <br /> predicted from the baseline soil survey, confirm soil map unit types, justify salvage <br /> tnic Y.ness, and evaluate soil suitability. Seil selvage occuxxed i n advance of the "A" pit <br /> during the 1999 field season as shown on dr awing 2W99-2A. A large portion of this soil uas <br /> placed on graded spoil north of "A" pit (drawing 2W99 -2 B) and the rest was placed in <br /> s[ockpi les J and R see Table 99.11. Observ ations within the mixed brush, sandstone-derived <br /> sorts indicated very suitable loamy soil was salvaged down to Che fxa ctuxed sandstone <br /> bedtoc k. The chic Y.ness of recovered soil ranged from 0.5 feet on a dget op5 to about 3.0 <br /> feet in Swale or drainage landscapes. <br />SCC will continue [o closely monitor sml handling operations during the 2000 field season. <br />Only sortable sources of soil within the disturbance area will he salvaged to ensure the <br />reclaimed areas are restored to the desired postmine land uses. SCC will obtain variances <br />pursuant ro Rule 4.06.2(2) and Pe [mit C-B2-057 whenever suitable soil cannot be salvagetl <br />exclusively from any map unit because of equipment limitations or operator safety concerns. <br />Soil Fit - Sorl Fertirity <br />Shallow pos[mi ne soil pits are e>:cavated pe uodically near representative revegetation <br />monitoring sites to evaluate plant roo[i ng charac [e a sci cs, determine soil fertility, <br />ensure spoil sui[nbilit y, and compare soil/spoil data with site-specific revegeta lion data. <br />The pits ere selected using an intensity of one pit per 25 acres of reclamation. Postmine <br />soil pits are placed within re clams iron blocks that have been soiled and seeded fo[ a <br />minimum of three years. Simila[ minirtmm time frames are used for monitoring postmine <br />vegetation. The pe rmanen[ vegetation has yene rally established sufficiently after three to <br />four years [o evaluate interactions between rooting depths and soil/spoil quality (Schafer <br />et al ., 1959). <br />Sail Pi[s were tluq on.
