The mining and reclamation may affect the groundwater table surrounding the mine site. The proposed mitigation efforts to minimize these impacts are recharge ponds or ditches in necessary areas to maintain groundwater levels during the mining, and a perimeter drain if needed to convey groundwater around the lined reservoir after the pit side liner is installed. J-2 Contracting Company proposes that they monitor groundwater levels through both interior (within phases of the mining) and exterior (outside the slurry wall lining) monitoring wells that they have installed, or have access to before, during, and after the mining and reclamation is complete so that impacts to the groundwater table, from this mining operation, can be identified and addressed. It is the intent of J-2 Contracting Company to operate responsibly and to mitigate any damage to wells that is directly attributable to the mining and reclamation of this site. Reclamation —Approximate Time Table The maximum proposed rate of production for the mine is 750,000 tons per year. The total time frame to mine all phases is approximately 30 years. The following table shows the approximate time frame to finish each phase of mining: Mine Phase and Acreage Time Frame to Complete and Reclaim Phase Phase 1 —24.36 acres 4 years Phase 2— 19.94 acres 3 years 6 months Phase 3—55.69 acres 10 years Phase 4—44.33 acres 8 years 5 months Phase 5—45.28 acres 7 years and 4 months The assumed annual production rate is 750,000 tons for processed material leaving the mine each year. The size and area of reclamation varies for each phase but generally consists of the outside mining slope being reclaimed at a 3H:1V and 3H:1V slope with the addition of overburden, topsoil, and revegetation. For more information on sequencing and size of the reclamation activities refer to Exhibit L financial warranty calculations. • J&T Consulting,Inc.
