MINING PLAN <br />1. General Mining Plan <br />EXHIBIT D <br />The property boundary has been surveyed on site and the permit area will be surveyed prior to <br />any site disturbance. Map C -3 shows the mining plan. <br />The gravel zone is approximately 20 feet thick in an alluvial deposit and is overlain by soil and <br />overburden ranging from 6 inches to 20 feet. The deposit will be mined in a four pit sequence, <br />beginning with the southwestern -most pit. The southwest and southeast pits (Pits 1 &2), along <br />with the southern phases of the two large northern pits (Pits 3 & 4), are on the lower terrace <br />while the northern halves of Pits 3 & 4 are on a terrace approximately 20 feet higher. Overburden <br />and topsoil will be removed via either bulldozer or scraper in all pits, establishing a 2H:1 V slope <br />in each pit. Initially, in Pit 1 (see Map C -3) overburden and topsoil is stockpiled to the immediate <br />northwest of the pit. Upon completion of the mining of Pit 1, the overburden stockpile will be <br />used to build both the 3H:1 V reclaimed slope and the wetland shelves as shown in Map F -1. The <br />overburden and topsoil removed from Phase 1 of Pit 2 was placed in the stockpile immediately <br />north of Pit 1 and will be placed in Pit 1 to complete the wetland shelves. The following phases' <br />overburden will be placed in the previously mined out phase(s) to build 3H:1 V reclaimed slopes <br />and wetland fringe. The initial overburden and topsoil from Pits 3 & 4 will be set aside, with the <br />overburden of each phase being placed in the previously excavated phase. The set aside <br />overburden and topsoil will be used to reclaim the final phase of each pit. <br />The maximum total tonnage sold from the site in any one calendar year is approximately 700,000 <br />tons, though the expected annual average is 600,000 tons. The raw material will be sold in three <br />products: sand and gravel, concrete, and asphalt. A break down of the product tonnages and <br />mined tonnages can be seen in Table D -1. The total disturbed area is 229.54 acres. A <br />breakdown of the estimated areas is included in Table D -2. <br />15 Road Pit May 14 D -1 <br />
