• 1993 Disturbance Area <br />The 1993 Annual Reclamation Report, Exhibit 93.1, shows the limits of disturbance as of <br />January 1, 1994. The disturbance line es 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 1993 includes the soil <br />removal area and soil stockpile JJ. The entire area totals 57.8 acres. <br />gackfillino end Gredina <br />Backfilling end grading operations occurred in the original box cut of the lower mining <br />block. A total of 8.3 acres were graded in 1993. These areas are shown on Exhibit 93.1, <br />1993 Annual Reclamation Report. <br />Light-use Roads <br />Peabody committed in TR-9 of Permit C-82.057 to listing and updating light-use road <br />locations and associated culvert locations in the Annual Reclamation Report. There was <br />no increase in light use road locations and associated culverts during the 1993 field <br />Season. <br />• Soil and SDOiI Nonitorino <br />Peabody is required by Permit C-82-057 to monitor the salvage, storage and redistribution <br />of soil and the spoil handling operations at Seneca II-W Mine. Specific programs include <br />documenting soil recovery, verifying soil redistribution thickness, determining final <br />graded spoil suitability in the Lennox Coat 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 far the 1993 calendar year. <br />Soil Recovery Documentation. Soil recovery limits end depths were recorded on the soil <br />map by Peabody's Western Division soil scientist on April 13, June 11, August 13, and <br />October 15 [o document [he actual thickness of soil recovered during the 1993 field <br />season. Color photographs of the soil profile and landscape were taken to verify the <br />thickness of soil recovered. The field notes and photographs for each soil observation <br />site are on file at the Peabody Western Division office in Flagstaff, Arizona. <br />• This quality control information is used fo verify soil salvage estimates predicted from <br />the baseline soil survey, confirm soil map unit types, justify salvage thickness, and <br />1 <br />
