EXHIBIT L—Reclamation Costs <br /> Reclamation Costs will be estimated based on the bond currently in place for the 53.9 original acres <br /> ($45,478) plus the estimated reclamation costs to address the 33.6 acres of proposed mining ground. <br /> The proposed 33.6 acre addition will include 6.5 acres of Osborn land and 27.1 acres of Wild Burro <br /> Investment property, both tracts lying adjacent to and immediately east of the current affected land's <br /> east boundary line. From stated average soil and overburden thickness,an average soil volume of 3 <br /> feet will be pushed to final location to meet grade specifications and minimum soil specification (12") <br /> over the mined out areas within the amended acreage area. Thus: <br /> Estimated soil/overburden to be pushed - (43560sgft/ac x 34ac=1,481,040 sq ft x 3 ft=4,443,120, cu <br /> ft= 164,560 cu yards x 1620#/yd/2000#/t= 133,293 tons <br /> From DRMS work sheets(2020) utilizing D-10 bulldozer capacities and costs from Cat Handbook: <br /> Average push distance: 150' <br /> Average push gradient: -5% <br /> Estimated Swell Factor: 1 <br /> Estimated adjusted productivity: 1800 tons per hour <br /> Estimated hours pushing soil and overburden to cover 33.6 acres: 74 hours <br /> Estimated Owning and Operating Cost (Cat Handbook,2020) $317.20/hour <br /> Total O&O Cost Estimate to bulldozer soil and overburden: $23,473 <br /> Estimate to compact backfilled highwall areas, <br /> 2500'x 150' = 375,000 sq ft/43560=8.6 acres <br /> 1111'x 200'= 222,200 sq ft/43560=5.1 acres <br /> Total acres undergoing compaction during backfilling: 14 x$200/acre $2800 <br />
