2.05.4(2)(b) <br />The following discussion forms the basis for the <br />following reclamation estimate: <br />Topsoil <br />It will be assumed that an equipment spread of two <br />651E scrapers and one D-9 push cat will be used to haul the <br />topsoil. Cycle times and productions are as follows. The CY/Hour <br />production figure assumes two scrapers, a 50 minute work hour, a <br />payload of 34.6 cubic yards of topsoil. The cost per cubic yard is <br />calculated using an hourly rate of $150 for the D-9 and $175 for <br />the 651E scrapers. <br />Load/Dump Haul Return Total CY/Hour <br />Topsoil Pile 3 1.3 0.9 0.7 2.9 597 <br />Topsoil Pile 4 - - - - - - - - - - <br />From topsoil pile 3 the production from the two <br />scrapers is 1,194 (597 X 2 scrapers) cubic yards per hour. At a <br />scraper spread cost of $500.00 per hour the unit cost to rehandle <br />the topsoil from pile 3 is $0.42 (500/1194). <br />Spoil From Ridges <br />• The method used to move spoil ridges into the <br />adjacent pits is to push it with a tractor dozer. The maximum push <br />distance is 90 feet, one pit. From edition 15 of the Caterpillar <br />performance handbook, it is estimated that a D-9 can push 1100 <br />cubic yards per hour with a 90' push distance. Assuming a D-9 <br />costs $150 per hour, the cost per cubic yard to move the spoil <br />ridges is $0.14. <br />Reclaim Sediment Pond F <br />Sediment Pond F was not constructed, therefore no <br />allowance for reclamation is required. <br />• <br />2.05-20iii September 1993 <br />
