East Cresson Overburden Storage Area Reclamation Costs (2008) <br />What is the footprint area of the ECOSA (acres)? 175.0 Map measurement <br />Measured from map provided by <br />What is the "median area" of the ECOSA (acres)? CCBV 4-9-08 83.0 "median area" for infiltration layer talcs <br />What is the thickness of the low infiltration layer (feet)? 3 feet <br />calculated low infiltration layer volume (from "median area") (cy) = 401,637 (median area x thickness x 1613 cy/ac ft) <br />hat is the ratio of compaction hours to total fleet hours? 0.75 Assumes scrapers will do significant compaction <br />Note: A major assumption in this cost estimate is that the OSA will be constructed in lifts from the bottom up and grading, <br />liming, growth medium placement, and revegetation will be concurrent with construction. It has also been assumed that <br />warranty liability will be figured at the point in time where the facility reaches the "median area" as measured from the maps. <br />aterial Cost <br />'ALightGrading (ac) 83 166.00 $ 33,129 $ 5,401 included $ 38,530 <br />D9 Rate (2 hrs/ac) <br />~eLiming 15 tons/ac 175 <br />972 Loader (ac/hr) 0.75 233.33 $ 25,803 $ 6,828 included $ 32,631 <br />D8 Dozer (ac/hr) 0.75 233.33 $ 37,163 $ 7,592 $ 188,607 $ 233,362 <br />ZLow Infiltration Layer 401,637 1,851 $ 395,014 $ 59,354 included $ 454,368 <br />Scraper Rate (cy/Ftr) 217 <br />Compaction Fleet hrs x0.75 1,388 $ 165,800 $ 43,252 included $ 209,053 <br />5K gal Water Truck Fleet hrs/2 925 $ 80,239 $ 26,223 included $ 106,463 <br />' 14H Grader Fleet hrs/2 925 $ 98,603 $ 28,835 included $ 127,438 <br />Haul Gr Medium (cy) 66,940 267.76 $ 90,923 $ 7,736 included $ 98,659 <br />777 Truck (ty/hr) 250 <br />988 Loader (cy/ttr) 750 89.25 $ 17,802 $ 2,612 included $ 20,414 <br />14 H Grader Fleet hrs/4 66.94 $ 7,132 $ 2,086 included $ 9,218 <br />5K gal HZO Truck Fleet hrs/4 66.94 $ 5,804 $ 1,897 included $ 7,701 <br />Spread Gr Medium (cy) 66,940 94.28 $ 18,816 $ 3,068 included $ 21,883 <br />D9 Rate(cy/hr) 710 <br />5Soi1 Analyses (#) 17 included included $ 341 $ 341 <br />Rate (ac /sample) 5 <br />ip 8 Fertilize (ac) 83.0 48.82 $ 1,996 $ 1,589 $ 10,292 $ 13,877 <br />D4 Rate (aGhr) 1.7 <br />'Seed & Harrow (ac) 74.7 32.48 $ 1,437 $ 1,057 $ 7,844 $ 10,337 <br />D4 Rate (ac/hr) 2.3 <br />BHand Seed (ac) 8.3 8.30 N/A $ 173 $ 872 $ 1,044 <br />Rate (ac/hr) 1.0 <br />9Hydro-Mulching (ac) 83.0 138.33 $ 4,105 $ 3,997 $ 43,405 $ 51,506 <br />Rate (ac/hr) 0.6 <br />°Plant Trees (ac) 83.0 123.9 N/A $ 2,577 $ 38,346 $ 40,923 <br />Rate (ac/ttr) 0.67 <br />Total Work Hours = 6,535.64 <br />"Supervisor (work hrs/4) 1,633.91 $ 22,300 $ 69,685 included $ 91,984 <br /> Subtotals = $ 1,006,065 $ 273,961 $ 289,706 $ 1,569,732 <br />Total Reclamation Cost Estimate for East Cresson OSA = $ 1,569,732 <br />'"Assumes light grading will be done with D9 dozer to "clean-up" and make surface ready to accept tow infiltration layer <br />'BAssumes liming at 15 tons/ac applied with D8 dozer & hopper (0.75 ac/hr) following grading and recontouring effort <br />2Compaction of the cap will be done using a Cat 815 Compactor, 14 H grader, and water truck for support <br />3Growth Medium Replacement fleet will consist of 988 loader, 4-777 trucks, 14G grader, and 5000 gal water truck <br />4Growth Medium will be spread using a D-9 dozer to a depth of 6 inches <br />SSoil analyses will be run on samples of the reclaimed areas to determine optimum fertilizer rates <br />eRipping and fertilizing will be conducted on replaced growth medium using a conventional D4 dozer with a cyclone spreader <br />~eeding and harrowing will be conducted on all replaced growth medium that is traversable with conventional equipment <br />BAssumes approximately 10% of the area will require hand-seeding to achieve revegetation <br />9Mulching will be conducted using conventional hydro-seeder/hydro-mulcher <br />10Assumes trees will be planted on the median area, because tree planting will be concurrent during operations <br />"Supervisor costs are figured at 25 percent of the total work hours to accomplish the reclamation effort <br />MDE (2-27-08); Rev (4-1-08 8 4-9-08) <br />
