RECLAMATION COSTS <br />EXHIBIT L <br />The worst case reclamation scenario will occur at the time that this revision is submitted in May <br />of 2014, when the work listed below is needed. This is the worst case since the lower portions of <br />Pits 3 and 4 have been opened up while Pits 1 and 2 are not completely done. There are <br />considerable overburden piles also present on site. Within 1 -2 years, it is expected that <br />backfilling of major portions of Pits 3 and 4 will occur and Lake Areas 1 and 2 will be <br />completely released. <br />Worst case reclamation items are listed below: <br />Backfill Lake 1 <br />Drain Lake 1 so that shelf wetlands can be installed by placing the overburden and topsoil on the <br />shelves in the lake. The pit requires pumping the water out to conduct the backfilling. The <br />volume of water to be pumped is 29.1 acres x 9 feet average depth. This is 11535123 cubic feet <br />or 86,282,724 gallons. Place overburden in the lake to produce 11.51 acres of shelf wetlands. <br />Since silt from previous washing is still in the bottom of the lake and accounting for the 3H:1 V <br />sidelsopes which have been backfilled, this results in an average fill depth of 9 feet. This depth <br />over 11.51 acres is a fill of 167,125 cubic yards. <br />Reclaim Lake 2 <br />As of May 2014, this lake only requires minor additional topsoiling of 8,000 cy in small areas <br />above the lake. Backfilling is complete. The area has been seeded but may require a second <br />seeding for adequate revegetation. Fringe wetlands have taken along the banks of the lake. The <br />area of seeding is approximately 7.0 acres of dryland above the lake. <br />Pits 3 and 4 Reclamation <br />The lower portions of Pits 3 and 4 are partially mined out and final backfilling is needed on these <br />areas as well as topsoiling and seeding the area. For the worst case, the pits will require pumping <br />the water out to conduct the backfilling. The volume of water to be pumped for Pit 3 is 8.75 <br />acres x 12 feet average depth. This is 4,573,800 cubic feet or 34,212,000 gallons. The volume of <br />15 Road Pit May 14 L -1 <br />
