EXHIBIT L-Reclamation Cost It is estimated that mining operations will possibly be conducted on the site from twenty to fifty years. Reclamation at the site will be done generally "concumenP' with the active mining activities. As mining proceeds from lift to lift the "mined" upslope bench areas will be sloped and final graded and have topsoil placed and seeded. For reclamation and financial warranty purposes [he site will be divided into Iwo Mine Phase Areas: • Phase I Area of 17.94 acres (west half) • Phase 2 Area of l6 acres. (east half) The entire Phase I Area will be mined and reclaimed prior to moving into [he Phase 2 Area. Some disturbance will occur in the Phase 2 Area during Phase I operations along the haul/access road where temporary product stockpiling may be located. This disturbance will be less than LS acres and will lie along the "old stage road trace" which is adjacent to the haul road. The haul road will remain as a farm road for the landowners use after mining and reclamation activities at [he site are completed and will no require reclamation. Approximately 6 acres of [he total 39.74 acres within the proposed permit area consists of wetlands which will not be disturbed and will require no reclamation- This area will be protected and separated by silt fencing and a 50 foot buffer zone above the entire wetland/creek area. In each of the mine phase areas the gravel deposits at the site will be removed to the underlying shale moving downslope in approximate 20-foot lifts. Topsoil from [he "initial" lift will be stockpiled iu a 50-foot buffer zone along [he west and north site perimeter (Phase I Area). Any available topsoil will be salvaged and stockpiled on the west and north sides of each lift to be spread on the remaining slopes after gravel extraction and final grading. As each lift is completed, the slopes will be graded to match the surrounding topography leaving a gradual slope from west to east along the east flank of the large north/south trending ridge. There will be no final highwall requiring reduction since mining will proceed from upslope areas to downslope areas and the gravel deposits will be removed to the underlying weathered shale. I[ is estimated that a total of five days to one week will be required for Phase I area of 17.94 acres of reclamation. The estimated total reclamation costs for 17-acres are as follows: Slope and grade [o surrounding topographic slopes, Final grade and Topsoil Placement = $8200.00 (Ca[ Dozer/grader, scraper for topsoil placement) Cat D-6M or D-SM Dozer (rip/grade 17acres) 30 hrs@ 125/hr= $3750.00 Tractor (with disc/harrow/seeder) 30 hours @ 110/hour = $3300.00 Seed Mix li5 PLS for 17 acres = $ 500.00 Compost material -straw mulch I OOOH/ac for 17 acres = $ 1500.00 Compost/mulch application 20 hrs- Tractor & spreader 110/hr = $ 2200.00 Total =$ 19,450.00 Contingency Cost I S% _ $ 2917.50 Administrative Costs ~% _ $ 97250 lbtal estimated reclamation cost = $23,340.00 This cost estimate includes fuel, mobilization, operators and associated labor.
