The costs are based on the assumption that if <br />Peabody Coal Company were to walk off the site, the State would need to <br />hire a contractor to complete the reclamation. In this type of an operation, <br />the mining sequence, is for the most part, followed immediately by the <br />reclamation phase. So, if the mine were to shut down some time in the <br />.future, the majority of the reclamation would have been completed. At <br />worst, there would be: <br />I. An open pit. <br />2. Topsoil and overburden stockpiles. <br />3. Haul road. <br />4. Areas awaiting bond release <br />It is to Peabody's best economic advantage to keep the reclamation as cur- <br />rent as possible and the number of stockpiles to a minimum in order to: I) <br />put the land behind mining back to wheat production; and 2) keep as much <br />area ahead of mining in wheat production. <br />Cost estimates were obtained from Rental Rate Blue Book for Construction <br />Equipment by Nielsen-Dataquest. <br />Production estimates were obtained from Caterpillar Performance Handbook <br />Edition 12 by Caterpillar Tractor Company. <br />GENERAL ASSUMPTIONS <br />I. Rental rate includes erection and dismantling equipment at mine site. <br />2. Monthly rental rates are based on regular shifts of 8 hours per doy, 40 <br />hours per week, 176 hours per month, for a total of twenty-two working <br />shifts per month. <br />L-I <br />
