<br />6.3.4 EXIIIBIT D -Reclamation Plan <br />(1) (a) Overburden Placement <br />No overburden will be mined in the operation. No other waste rock materials wIll be quamed. <br />Cropper fines will be created in the processing of the products; and chopper fines, if not sold, <br />will be placed and graded on the excavated pit floor for final reclamation. <br />SIo es <br />The overall slopes of the quarry will be less steep than 3H:1 V and are not anticipated to be over <br />15 feet high. The quarry slopes will consist of bench faces approximately 2 feet high with bench <br />widths of approximately 6 feet. Because the sandstone is fractured to varying degrees, the <br />quarry slopes are not anticipated to be uniform in dimension; however, all highwalls will be in <br />competent sandstone. The pit highwalls will be reclaimed ifpossible-depending upon the degree <br />of fracturing in the resulting benches. The post mining use of rangeland will be supported by <br />revegetating the quarry floors upon completion of mining using the seed mixture provided by the <br />N.R.C.S. <br />(c) Reclamation Measures <br />(i) Plant Growth Medium <br />Available soil and toose material (plant growth medium} will be stripped from the initial azea to <br />be mined and will be stockpiled on the existing level ama of the affected azea. The stockpile will <br />be vegetated, using the recommended N.R.C.S. seed mixture to protect against erosion. <br />• Chopper fines, if not sold, and other loose rocky material developed during the operation will be <br />retained and used to cover the exposed bedrock of the mined pit floor. This mixture of loose <br />material on areas of the pit floor no longer needed for processing will be covered with available <br />plant growth medium stripped from successive benches prior to mining. The final depth of plant <br />growth medium (including the crusher Fines and other loose rocky material) is not known at this <br />time, but is anticipated to average about one foot thick over the mined out pit floor. <br />Plant growth medium stockpiled from the initial mined azea will be used to revegetate the fmai <br />areas of the operation. <br />(ii) Seeding <br />Any area of the pit floor no longer needed for process/stockpile operations will be graded with <br />available reject process fine materials over the exposed bedrock, covered with available plant <br />growth medium stripped from pre-mining azeas, and seeded for re-vegetation. Seeding will be <br />done as recommended by the local N.R.C.S. office: between November 1 and April 30. It is <br />estimated that all of the pit floor will be utilized for processing and stockpiling for a year or two <br />before any portion would be vacated for seeding. <br />Fertilizer was not recommended by the local N.R.C.S. office. Please see Attachment 5 for the <br />recommendation from the local N.R.C.S, office. <br />• <br />
