e. Monitor groundwater levels adjacent to the site and mitigate any damage to adjacent <br /> wells that dewatering activities may have. (See Exhibit G) <br /> Groundwater—Specific Requirements <br /> The operation will not affect groundwater quality on or off the site. The operation will comply <br /> with State groundwater quality standards. <br /> The mining and reclamation may affect the groundwater table surrounding the mine site. The <br /> proposed mitigation efforts to minimize these impacts are recharge ponds or ditches in <br /> necessary areas to maintain groundwater levels during the mining, and a perimeter drain if <br /> needed to convey groundwater around the lined reservoir after the pit side liner is installed. J-2 <br /> Contracting Company proposes that they monitor groundwater levels through both interior <br /> (within phases of the mining) and exterior (outside the slurry wall lining) monitoring wells that <br /> they have installed, or have access to before, during, and after the mining and reclamation is <br /> complete so that impacts to the groundwater table, from this mining operation, can be identified <br /> and addressed. It is the intent of J-2 Contracting Company to operate responsibly and to <br /> mitigate any damage to wells that is directly attributable to the mining and reclamation of this <br /> site. <br /> Reclamation —Approximate Time Table <br /> The maximum proposed rate of production for the mine is 750,000 tons per year. The total time <br /> frame to mine all phases is approximately 30 years. The following table shows the approximate <br /> time frame to finish each phase of mining: <br /> Mine Phase and Acreage Time Frame to Complete and <br /> Reclaim Phase <br /> Phase 1 —24.57 acres 4 years <br /> Phase 2—20.08 acres 3 years 6 months <br /> Phase 3—56.19 acres 10 years <br /> Phase 4—44.10 acres 8 years 5 months <br /> Phase 5—45.43 acres 7 years and 4 months <br /> The assumed annual production rate is 750,000 tons for processed material leaving the mine <br /> each year. The size and area of reclamation varies for each phase but generally consists of the <br /> outside mining slope being reclaimed at a 3H:1V and 3H:1V slope with the addition of <br /> overburden, topsoil, and revegetation. For more information on sequencing and size of the <br /> reclamation activities refer to Exhibit L financial warranty calculations. <br /> �' J&T Consulting,Inc.
