Yoast Mine 2003 Annual Reclamation Report 2003 Disturbance Area The Yoast Mine 2003 Reclamation Map shows the limits of disturbance as of December 31, 2003. The disturbance line as shown on this drawing depicts all disturbance associated with the mining operation including haul road and pond construction, topsoil removal and storage, open pits, spoil piles, etc. The azea disturbed during 2003 totals 38.1 acres. Backfilling and Grading During 2003, SCC graded a portion of the active pit spoil. This area totals 76.8 acres and is shown on the • Yoast Mine 2003 Reclamation Map. Soil and Sooil Monitorine SCC is required by Permit C-94-082 to monitor the salvage, storage, and redistribution of soil and spoil handling operations a[ Yoast Mine. Specific programs include documenting soil recovery, verifying soil redistribution thickness, determining final graded spoil quality, determining soil fertility, evaluating plant rooting characteristics, recording the source of replaced soil, and completing an annual soil balance. The following sections present the soil and spoil monitoring data for the 2003 calendar year. Soil Recovery Documentation Soil recovery was documented by daily observation by the grading foreman and pit supervisor. This quality control information is used to verify soil salvage estimates predicted from the baseline soil survey, con£um soil map unit types, justify salvage thickness, and evaluate soil suitability. Soil salvage occurred in advance of the active pit during the 2003 field season as shown on the Yoast Mine 2003 Reclamation Map. All topsoil salvaged during this period was placed in stockpiles M, and O (see Table 03.1). • SCC will continue to closely monitor soil-handling operations during the 2004 field season. Only suitable sources of soil within the disturbance area will be salvaged to ensure the reclaimed areas are restored to the desired postmine land uses. SCC will obtain variances pursuant to Rule 4.06.2(2) and Permit C-94-082 2
