<br />Yoast Mine 2001 Annual Reclamation Report <br />2001 Disturbance Area <br />The 2001 Annual Reclamation Map shows the limits of disturbance as of December 3l, 2001. The <br />disturbance line as shown on this drawing depicts all disturbance associated with the mining operation <br />including haul road and pond construction, topsoil removal and storage, open pits, spoil piles, etc. The <br />area disturbed during 2601 totals 81.9 acres. <br />Backfilline and Grading <br />During 2001, SCC graded a portion of the active pit spoil. This area totals 82.3 acres and is shown on the <br />Annual Reclamation Map included in this report. <br />• <br />Soil and Spoil Monitoring <br />SCC is required by Permit C-94-082 to monitor the salvage, storage, and redistribution of soil and spoil <br />handling operations at Yoast Mine. Specific programs include documenting soil recovery, verifying soil <br />redistribution thickness, determining final graded spoil quality, determining soil fertility, evaluating plant <br />rooting characteristics, recording the source of replaced soil, and completing an annual soil balance. The <br />following sections present the soil and spoil monitoring data for the 2001 calendaz year. <br />Soil Recovery Documentation <br />Soil recovery was documented by daily observation by the grading foreman and pit supervisor. This quality <br />control information is used to verify soil salvage estimates predicted from the baseline soil survey, confirm <br />soil map unit types, justify salvage thickness, and evaluate soil suitability. Soil salvage occurred in advance <br />of the active pit during the 2001 field season as shown on the ARR map. All topsoil salvaged during this <br />period was placed in stockpiles O, P, and R (see Table 00.1), <br />SCC will continue to closely monitor soil-handling operations during the 2002 field season. Only suitable <br />• sources of soil within the disturbance area will be salvaged to ensure the reclaimed areas are restored to the <br />desired postmine land uses. SCC will obtain variances pursuant to Rule 4.06,2(2) and Permit C-94-082 <br />whenever suitable soil cannot be salvaged exclusively from any map unit because of equipment limitations <br />or operator safety concerns. <br />2 <br />
