groundwater around the lined reservoir after the pit side liner is installed. A ground water model <br /> by McGrane Water Engineering, LLC has also been provided and the results indicate that water <br /> levels will be affected by +/-0.5 to +/-1 ft and there are 5 wells (2 are owned by IHC Scott, Inc.) <br /> within the predicted water level change so the overall impact of the slurry wall and clay liner will <br /> be insignificant. IHC Scott, Inc. proposes that they monitor groundwater levels through both <br /> interior (within the mining) and exterior (outside the slurry wall lining) monitoring wells that they <br /> have installed, or have access to before, during, and after the mining and reclamation is complete <br /> so that impacts to the groundwater table, from this mining operation, can be identified and <br /> addressed. It is the intent of IHC Scott, Inc. to operate responsibly and to mitigate any damage to <br /> wells that is directly attributable to the mining and reclamation of this site. <br /> Reclamation—Approximate Time Table <br /> The initial proposed rate of production for the mine is 300,000 tons per year and the maximum <br /> proposed rate of production for the mine is 1,000,000 tons per year. The total time frame to mine <br /> all phases assuming an average production rate of 650,000 tons per year is approximately 12 <br /> years. The following table shows the approximate time frame to finish each phase of mining <br /> assuming an average production rate of 650,000 tons per year: <br /> Mine Phase and Acreage Time Frame to Complete and <br /> Reclaim Phase <br /> Phase 1 —98.24 acres 11 years <br /> The assumed annual production rate is 300,000 tons initially to 1,000,000 tons maximum for <br /> processed material leaving the mine each year. The size and area of reclamation generally <br /> consists of the outside mining slope (mined at a 2H:1V slope) in in Phase 1 being reclaimed at a <br /> 4.51-1:1 V slope with the addition of clay, overburden, topsoil, and revegetation.
