1994 Disturbance Area <br />• the 1994 Annual Reclamation Report, Exhibit 94.1, shows 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 end Grading <br />BackfilLing and grading operations occurred in the original box cut of the lower 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 />Lich[-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 />SLC is required by Permit C-82-057 to monitor the salvage, storage, and redistri 6uti on of <br />soil and the spoil handling operations at Seneca II-N 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 Coal Company's (PWCC) 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 pr ofiLe 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 Flagstaff, Arizona. <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 the "A" and North pits <br />
