Fremont requests modification of the original mine plan submitted in 2000 to reflect project conditions as directed by Stonewall. Mining will be conducted within each phase of varying acreage as a dry operation via dewatering. Phase 1 includes 94 acres but will be mined out in less than one year, with only 19 acres left to be mined. Bonding will be posted to cover one entire phase. Perimeter dewatering trenches will collect groundwater which will be pumped into the settling pond prior to discharge into the Arkansas River. At the beginning of each phase, topsoil will be removed with scrapers and stockpiled along the phase perimeter to be used in reclamation. Overburden and naturals will initially be stockpiled with ultimate use in 3:1 slope construction and pit backfill. Once mining has exposed shale, the mine floor limit, mining will proceed through the reserve. Reclamation, as slope construction, will occur concurrently with mining until a phase is mined out. Slope construction will utilize overburden and naturals thus reducing the need stockpiles. As mine floor develops, any necessary stockpiles will be located in the pit floor or adjacent to the production stage. Aggregate will be excavated with front end loaders and transported to the production stage by over land conveyors. Bulldozers will be used to push down highwalls to MSHA compliant slopes. Fremont requests modification of the original reclamation plan submitted in 2000 to reflect current project conditions as directed by Stonewall. Final reclamation is a water storage pond. Of the currently developed 154 acres, water storage is proposed for 90 acres. The remaining approximately 60 acres will be contoured and seeded as rangeland. The water storage pond will be sloped 3:1 using bulldozers, loaders and scrapers utilizing overburden and naturals. Excess naturals and overburden will be distributed over the remaining 60 acres with scrapers and loaders. The material will be contoured and compacted with dozers and excavators. Upon completion of slope construction and rangeland area contouring, 4 to 6 inches of topsoil will be placed across the 60 acres and along the perimeter of the pond. The approved seed mix will be placed, mulched and crimped using farm equipment. Please contact me directly with any questions. Respectfully submitted, Angela M.
