reclaim the exposed portion of the south facing slope, the soil from Strip 2 will be added to the <br />stockpile for later reclamation of yet unmined portions of the south facing slope. The stockpile will <br />then contain 4670 cy. <br />d) Mine Strip 4: 3.50 acres - It is expected that the salvageable soil in Strip 3 will average 3 inches, <br />therefore, 3 inches x 3.50 acres = 1411 cy will be salvaged. All of this topsoil will be placed on the <br />2.35 acres of the south facing slope in the Strip 3 azea to a depth of 9 inches. This will require 2843 <br />cy. Therefore, an additional 1432 cy will be taken from the stockpile. The stockpile should then <br />contain 4670 cy - 1432 cy = 3237 cy. An amount of 2360 cy of this stockpiled quantity will be used <br />in the reclamation of the sediment ponds, traps, ditches and minor portions of the access below Strip <br />4. The remainder will be added as a thin topsoil layer to the flat azeas designated for irrigation. This <br />material will be moved during final reclamation. <br />Overburden Calculations <br />The stockpile as of December 2005 will be used as topsoil, therefore, there is no overburden pile on <br />the site as of this date. As Strip 2 is mined over the 2.6 acres, overburden from the excavation will be <br />approximately 4196 cy, which will be backfilled on a portion of the original pit azea. It is estimated <br />that the thickness salvaged over the 2.6 acres will be approximately 1.0 feet. This overburden will be <br />used as substitute soil on the flat azeas, which will later be irrigated. Good topsoil will be used on the <br />north facing slope, which will not be irrigated. Using an average replacement depth of 1.5 feet, the <br />4196 cy will cover 1.7 acres. Once Strip 2 is mined out, this will leave 7.6 ac (total flat azea in Strips <br />1, 2 and old pit) -1.7 ac (already covered) = 5.9 acres left to cover. <br />This will consume all the overburden from the mining of Strip 2. The overburden from Strip 3 (4.47 <br />acres) is expected to average approximately 2.4 feet thickness, therefore, 17308 cy will be excavated. <br />At a replacement thickness of 1.5 feet, one acre will require 2419 cubic yards of overburden for <br />reclamation. One acre will be covered, using up 2419 cy. This leaves 14888 cy to be moved to the <br />stockpile area shown on Map C-2. This reclamation will leave 4.9 acres of the flat azea in Strips 1, 2 <br />and the old pit to reclaim. Overburden from Strip 4 is excavated, with an approximate thickness of <br />Bellgazdt Pit 1/06 19 <br />
