In addition the following information is <br />provided to address the concerns you enumerated. <br />1. Top soil and overburden stockpiles will be segregated. Topsoil <br />stockpiles will be identified with signs. <br />2. Top soil will be removed to a depth of no more than 6 inches. <br />We anticipate that mining will take more than one season, therefore <br />top soil stockpiles will be sloped to 3:1 and revegetated. <br />Revegetation will include a general seed type from recommended <br />mixture to establish a vegetative cover. See Revised EXHIBIT D. <br />3. Reject materials will be stockpiles and if there is no market <br />for the reject materials, then the rejects will be graded out over <br />the floor of the pit and covered with overburden. <br />4. Our plan to manage stormwater will be to mine in a manner that <br />creates a natural holding area for stormwater. Overburden <br />stockpiles will be placed along the sides and southern perimeter of <br />the permit boundaries for ease of storage and stopping any flow of <br />stormwater from the pit. The southeast corner of the pit will be <br />the low point. As the mining proceeds, a berm constructed from <br />overburden will be placed along the southern and southeasterly <br />boundary of the pit to retain the stormwater. The typical plan for <br />the berm is shown on the revised Mining Plan Map. <br />5. The previously mined area is now shown on the map. The area is <br />a convenient source of sandy, gravely material and was used for pit <br />run material. To our knowledge, no one has processed material at <br />the pit. The portion of the previously mined area outside of the <br />proposed permit boundary is also shown. As future home sites and <br />subdivision roads are constructed, previous uses will likely be <br />changed. <br />AN EQUAL OPPORTUNITY EMPLOYER <br />
