EXHIBIT E RECLAMATION PLAN 1. General Reclamation Plan Post-mining land use will return the entire disturbed site back to pastureland with native grasses on all slopes and is consistent with existing land use in the area. All slopes will be reclaimed to 3H:1 V or shallower. As described in the mining plan, reclamation will occur concurrently with mining. Overburden will be pushed at a 3H:1 V slope to the adjacent phase in reclamation resulting in only 15 vertical feet of active 3H:1 V dozer pushed down highwall at any given time. No more than 400 lateral feet of highwall will remain in need of knockdown at any time. Topsoil and overburden from the current mining phase will be used to reclaim the previous mined out phase. It is anticipated that backfilling and seeding will occur at 1 to 2-year intervals until the site is completely mined. As the first area is opened, topsoil and overburden will be stockpiled to be used for that phase's reclamation post mining. If topsoil and overburden berms are in place longer than 6 months, the berms will be seeded with clover to diminish wind erosion. Topsoil will be replaced to a depth of 4 inches. When dispersed, overburden will be placed and compacted to at least 6" depth. By using onsite stockpiled materials and completing reclamation of mined areas concurrent with active mining, the distance that topsoil and overburden is transported, as well as the amount of material to be rehandled, will be minimized. Additionally, mined and unreclaimed acreage will be minimized and will make the worst-case reclamation area smaller thus decreasing the required bond. The internal haul road will be reclaimed at the end of the mine life. 2. Reclamation Timetable Reclamation will take place concurrently with mining with an additional estimated 6 months of reclamation commencing after mining is completed.
