Arcoca in._ ARCOSA <br /> Exhibit E—Reclamation Plan <br /> An unreclaimed quarry of approximately 30 acres currently exists at the site. Figure D. I shows the <br /> original unreclaimed quarry site, overburden stockpiles, and other general features as they originally <br /> existed prior to issuance of Permit No. M-1988-108. This quarry was originally mined by Great Western <br /> Aggregates between 1962 and 1975. On the basis of site inspections, it is apparent that Great Western <br /> made no attempt to segregate topsoil from other overburden when the quarry was originally developed. <br /> Consequently, the reclamation plan presented herein takes into consideration disadvantageous <br /> conditions that correspond to the prelaw operations of Great Western Aggregates and utilizes our best <br /> efforts to assure reasonable compliance with Division performance requirements for site reclamation. <br /> Current Conditions <br /> As stated above, Great Western Aggregates operated a quarry at the site in the 1960's and early <br /> 1970's. As this was a prelaw operation, little consideration was given to post mining reclamation such <br /> as segregation of topsoil and mining in a manner to assure post mining slope stability. In fact,when <br /> operations ceased in 1975, no reclamation work was undertaken. Figure D.1 portrays the quarry as it <br /> existed prior to issuance of Permit No. M-1988-108. <br /> Reclamation Goals <br /> Reclamation in the area of the quarry will be for a post mining land use of rangeland consisting of mixed <br /> grasses,forbs, and shrubs. The land owner also has requested that a small (approximately10-acre) <br /> pond be left for stock watering purposes.Wildlife use of the site at present is low due to the proximity of <br /> the quarry to Highway 93. Post mining reclamation will enhance the suitability of the site as a rangeland <br /> and wildlife habitat. <br /> The processing plant will remain when mining operations cease. The plant will be converted to another <br /> beneficial use such as cement production, lime production, or another related activity. <br /> Reclamation Philosophy <br /> The current mine plan as detailed in Exhibit D calls mining the existing quarry to an elevation of 5,860 <br /> feet and progressively mining southward as process plant needs warrant. <br /> Contemporaneous reclamation will be conducted by pushing the overburden berms on the edges of the <br /> quarry into the quarry via dozer to establish final slopes no steeper than 5 H to 3 V and to cover the <br /> quarry bottom. This grade is consistent with the slopes around Coal Creek and the surrounding area. <br /> Sufficient overburden materials exists in the berms to backfill the slopes and cover Pierre shale <br /> materials on the lower slopes and quarry bottom to a depth of 2 to 4 feet. <br /> Since topsoil was not originally segregated when Great Western developed the quarry, revegetation <br /> efforts will be somewhat hampered. However,we propose a plan which should largely mitigate this <br /> problem. In regard to topsoil availability, the only source of topsoil is that which overlies presently <br />
