1994 Disturbance Area <br />• The 1994 Annual Reclamation Report, Exhibit 94.1, shoos the limits of disturbance as of <br />January 1, 1995. The disturbance Line as shown on this exhibit depicts all disturbance <br />associated with the mining operation including haul road construction, soil removal and <br />storage, open pits, spoil piles, etc. The area disturbed in 1994 totals 62.0 acres. <br />Backfilling and Gradinn <br />Backfilling and grading operations occurred in the original box cut of the loner mining <br />block, "A" pit, and "B" pit. A total of 54.0 acres were graded in 1994. These areas are <br />shown on Exhibit 94.2, 1994 Annual Reclamation Report. <br />Light-use Roads <br />Seneca Coal Company (SCC) committed in TR-9 of Permit C-82-057 to listing and updating <br />light-use road locations and associated culvert locations in the Annual Reclamation <br />Report. There was no increase in light use road locations and associated culverts during <br />the 1994 field season. <br />Soil and Sooil Monitoring <br />• SCC is required by Permit C-82-057 to monitor [he salvage, storage, and redistribution of <br />soil and the spoil handling operations at Seneca II-U Mine. Specific programs include <br />documenting soil recovery, verifying soil redistribution thickness, determining final <br />graded spoil suitability in the Lennox Coal outcrop sampling area, determining soil <br />fertility, evaluating plant rooting characteristics, recording the source of replaced <br />soil, and completing an annual soil balance. The following sections present the soil and <br />spoil monitoring data for the 1994 calendar year. <br />Soil Recovery Documentation. Soil recovery limits and depths were recorded on the soil <br />map by Peabody Western Loa( Company's (PYCC) soil scientist on September 11, 1994 to <br />document 'the actual thickness of soil recovered during the 1994 field season. Color <br />photographs of the soil profile and landscape were taken to verify the thickness of soil <br />recovered. The field notes and photographs for each soil observation site are on file at <br />SCC's Corporate office in FLagst of f, Artzona. <br />This quality control information is used to verify soil salvage estimates predicted from <br />• the baseline soil survey, confirm soil map unit types, justify salvage thickness, and <br />evaluate soil suitability. Soil salvage occurred in advance of [he "A" and North pits <br />1 <br />
