RECLAMATION COST ESTIMATE <br /> The following Reclamation Cost estimate is based on the as- <br /> sumption that there will be no more than 9.3 acres ± of disturbance <br /> at any-one-time this would include stripped, partially mine and <br /> partially reclaimed areas . The mine working face will be 700 feet <br /> long and graded 2h to lv as mining progresses . This graded slope <br /> would require finish grading, resoiling and seeding. <br /> This bond then includes resoiling and seeding on 5 . 0 acres . <br /> When it comes time to resoil the area, an average of 6 inches of <br /> growth medium that has been salvaged will be spread over the dis- <br /> turbed area (5 . 0 acres) . At that time there would be 4, 033 cubic <br /> yards of growth medium that needs to be spread and 0 . 82 acres of <br /> finish slope grading on the working area. The table below outlines <br /> the various areas of disturbance at the time explained above. A <br /> Cat 631G scraper is used to do the resoiling in this calculation <br /> and the seedbed and final slope grading uses a Cat 140G motor <br /> grader. The mobilization haul distance from Campo is 15 miles. <br /> The revegetation cost figure used includes fertilizer, grass seed, <br /> labor and drilling costs . <br /> STAGE TOTAL SOIL DEPTH <br /> NEEDING RESOILING 5.00 AC. 6 <br /> REVEGETATION AREA 5.00 AC. <br /> RESOIL @ 6It 4,033 CUBIC YARDS <br /> ESTIMATED UNIT COSTS FOR RECLAMATION ITEMS: <br /> Unit Cost <br /> 1 .
