• Seneca II-W 2002 Annual Reclamation Report <br />2002 Disturbance Area <br />The Seneca II-W Mine 2002 Reclamation Map, found in the Exhibits section of the 2002 Annual <br />Reclamation Report shows the limits of disturbance as of December 31, 2002. The disturbance line as <br />shown on this drawing depicts all disturbance associated with the mining operation including haul road and <br />pond construction, topsoil removal and storage, open pits, spoil piles, etc. The area disturbed in 2002 totals <br />28.2 acres. <br />BacktillinE and Gradine <br />Backfilling and grading operations occurted in [he "A" pi[ and "D" Pit area. A total of 99.2 acres were final <br />graded in 2002. This area is shown on [he Seneca II-W Mine 2002 Reclamation Map. <br />Licht-use Raads <br />No new light-use roads were added during the 2002 field season. Haul road "L" was constructed during <br />November of 2002. <br />Soil and Spoil Monitorine <br />SCC is required by Permit C-82-05'7 to monitor the salvage, storage, and redistribution of soil and spoil <br />handling operations at Seneca II-W Mine. Specific programs include documenting soil recovery, verifying <br />soil redistribution thickness, determining final graded spoil suitability in the Lennox Coal outcrop sampling <br />area, determining soil fertility, evaluating plant rooting characteristics, recording the source of replaced soil, <br />and completing an annual soil balance. The following sections present the soil and spoil monitoring data for <br />the 2002 calendar year. <br />Soil Recovery Documentation <br />Soil recovery was documented by daily observation by [he 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 "South" pi[ during the 2002 field season as shown on [he Annual Reclamation Map. Topsoil was <br />removed in advance of 2W south pits as shown, and was recovered in advance of the construction of Haul <br />Road "L". Observations within [he mixed brush, sandstone-derived soils indicated very suitable loamy soil <br />was salvaged down to the fractured sandstone bedrock. The thickness of recovered soil ranged from 25 feet <br />. nn ridge tops to about 3.0 feet in Swale or drainage landscapes. Recovered soil was directly hauled [o graded <br />spoil of "A" pit. <br />
