• • SENECA II MINE 2007 ANNUAL RECLAMATION REPORT 2007 DISTURBANCE AREA No additional acres were disturbed during 2007. The total disturbed area remains at 2,295.3 acres. However, during a 2007 Division inspection visit, it was brought to SCC's attention that the Division felt there was a discrepancy in the total acres permitted for disturbance and the disturbed acreage reported in the 2006 Annual Reclamation Report. SCC has researched the issue and has the following explanation for the potential discrepancy: As the Division knows there are two (2) primary categories of disturbance at Seneca II Mine: Pre- Law and SMCRA (permanent program). • Pre-Law disturbed acres = 326.5 acres • Pre-Law Total Bond Release acres = 257.7 acres 68.8 acres disturbed and not released Within the SMCRA category, there are acres approved for disturbance and acres actually disturbed. • SMCRA (permanent program acres approved for disturbance = 2,128.0 acres • SMCRA (permanent program)acres physically disturbed = 1.968.8 acres 159.2 acres not disturbed In hindsight, these acres should never have been added or reported together, since it has caused confusion within the Division's accounting system. Additional confusion has been incurred now that the recent Pre-Law bond release of 257.7 acres was subtracted from the initial 2,128 approved disturbed acres giving a new total of 1,870.3 acres. The actual disturbed acres are 159.2 acres less than the 2,128 acres approved for disturbance. In summary, the inadvertent reporting of the Pre-Law acres in combination with the permanent program acres has caused considerable confusion. However, the bottom line is that there is no exceedence associated with the permitted disturbance acreage. The new acreage is reflected on the CDRMS Annual Report Form and is included in the text of the following report. The 2007 Reclamation Map portrays the extent of the disturbance boundaries. BACKFILLING AND GRADING There were 8 acres backfilled and graded associated with the solid waste disposal site which is included in the SMCRA permit area. In addition five (5) new "V" ditches were constructed in the 125.8 acres of the East Wadge Pit specifically excluded from the. 2006 Phase I Bond Release application. There were also, 67.4 acres of Wolf Creek Pre-Law area backfilled and graded during 2007. SOIL AND SPOIL MONITORING SCC is required by Permit C-80-005 to monitor the salvage, storage, and redistribution of soil and . spoil handling operations at Seneca II Mine. Specific programs include documenting soil recovery, verifying soil redistribution thickness, determining final graded spoil quality and 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 2007 calendar year.
