<br />already mined previously. This process really <br />should only require stockpiling of topsoil <br />from the mining operation (about 2 acres at <br />any one time) for the very first cut. This <br />should amount to about 100 to 120 cubic yards <br />which is part of the above mentioned 150 cubic <br />yards. <br />_.

All of these <br />are for visual enhancement as well. <br />4 <br />Engineering & Environmental <br />
