<br />Rindahl & Associates- <br />Therefore, the suggested bond is to equal the cost of <br />reclaiming the site as presented here. <br />2. After evaluating the sequence of events, we find that your <br />calculations are still correct. The estimate of 311 cubic <br />yards as presented, is correct. The problem appears to be <br />related to the handling of the subsoil which is sandy loam <br />and which is also the commodity being mined. Clarification. <br />The subsoil will be used in an over-the-shoulder reclamation <br />method of plant-growth medium ("topsoil") replacement. It <br />will not be stockpiled as plant-growth medium, only as mined <br />material to be sold. As an area is mined, it will be graded <br />with b inches of "subsoil" (material being mined) and have 2 <br />tons per acre of weed-free manure incorporated. Then, the <br />resultant plant-growth medium will be compositely sampled for <br />analysis in order tv determine other amendment requirements. <br />Hopefully, this explanation resolves the issue and answers <br />your question. <br />Er.hibit E <br />2. The structures on site are permanent and will remain after <br />mining and reclamation are complete. <br />5. The pond will be approximately 8 feet deep. The pond will be <br />sealed with the clay from beneath the mined material. Ground <br />water is contained aquifer. The "perched water" is a result <br />of precipitation, infiltration and percolation and does not <br />remain for an extended period of time. <br />6. The material being mined is generally going to 6e sand. The <br />sand is generally greater than 60 inches deep (as defined by <br />the 5oi1 Conservation Service for the Blakeland soil series) <br />and in the permit area is expected to be 15 to 20 feet deep. <br />There will not be complete removal of the sand to bedrock or <br />to the underlying clay, where and when it does occur. The <br />expected depth of excavation is not anticipated to e::teed 10 <br />feet. This would leave between S and 10 feet of rooting <br />depth in addition to the b inches (average) of plant-groaith <br />medium being replaced. <br />In short, there will be a minimum of b inches of product left <br />below the plant-growth medium being replaced. <br />7. Your assumption is correct. Because the mulch is to be <br />crimped, the intended method of seeding is now to be by <br />drill. If at sometime a change to broadcast seeding is <br />necessary, the operator will double the rates and notify the <br />MLRB. <br />2 <br />& Environmental <br />
