• No incidental products will be mined/extracted at the Buffalo Stone Quarry. <br />Chopper fines maybe sold. <br />(ul Explosive Use <br />Explosives will not be used to break up the limestone. <br />6.3.4 EXHIBIT D- Reclamation Plan <br />(1) (al Overburden Placement <br />No overburden will be mined in the operation. No other waste rock materials will <br />be quarried. Chopper fines will be created in the processing of the products; and <br />chopper fines, if not sold, will be placed and graded on the excavated pit floor for final <br />reclamation. <br />Slo s <br />The overall slopes of the quarry will be less steep than 3H: 1 V and aze not <br />anticipated to be over 15 feet high. The quarry slopes will consist of bench faces <br />approximately 2 feet high with bench widths of approximately 6 feet. Because the <br />limestone is fractured to varying degrees, the quarry slopes are not anticipated to <br />be uniform in dimension; however, all high walls will be in competent limestone. <br />The pit high walls will be reclaimed if possible-depending upon the degree of <br />fracturing in the resulting benches. The post mining use of rangeland will be <br />• supported by revegetating the quarry floors upon completion of mining using the seed <br />mixture provided by the N.R.C.S. <br />(cl Reclamation Measures <br />(i) Plant Crrowth Medium <br />Available soil and loose material (plant growth medium) will be stripped from the <br />initial azea to be mined and will be stockpiled on the east area of the affected area. <br />The stockpile will be vegetated, using the recommended N.R.C.S. seed mixture to <br />protect against erosion. Attachment 5, page 14 <br />Chopper fines, if not sold, and other loose rock material developed during the <br />operation will be retained and used to cover the exposed bedrock of the mined pit <br />floor. This mixture of loose material on areas of the pit floor no longer needed for <br />processing will be covered with available plant growth medium stripped from <br />successive benches prior to mining. The final depth of plant growth medium <br />(including the chopper fines and other loose rock material) is not known at this time, <br />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 <br />revegetate the final areas of the operation. <br />ii) Seeding <br />Any azea of the pit floor no longer needed for process/stockpile operations will be <br />• graded with available reject process fine materials over the exposed bedrock, <br />covered with available plant growth medium stripped from pre-mining areas, and <br />
