• In reference to the areas requiring repair, the topsoil removal area <br />will be dictated by the equipment selected to do the repair. For <br />example, if 100 ton trucks are used to transport riprap material, a 200 <br />foot circle work area will be required. In the event smaller trucks or <br />equipment are used, then the work area would be reduced accordingly. <br />For the purpose of the permit revision application, the work area will <br />be approximately 200 feet wide along the entire length of the repair <br />area. Colorado Yampa Coal Company will try to minimize the size of the <br />work area whenever possible. <br />The anticipated range of volumes for the various areas are as follows: <br />Area YD <br />7 21,780 <br />31 26,620 <br />41 50,820 <br />51 24,200 <br />51W 14,520 <br />The volumes are based on an 18 inch salvage depth and these may be <br />modified, based upon results of topsoil test depths determined by <br />testing plan. <br />During the final grading of Area 61, some topsoil may be pushed back <br />from the working area. This will allow equipment maneuverability when <br />the graded spoil is blended with the adjacent areas. <br />• (6) Overburden <br />A narrative and appropriate <br />storage of all overburden materia <br />include pit dimensions, overburde <br />each phase of the ro osed operat <br />development waste disDOSaI sti <br />Temporary overburden and undergror <br />shall comply with the ~ lp icable <br />to demonstrate such compliance <br />geometry, and method of material <br />operation, each plan should also i <br />~)_ A surface b <br />explaining how the applicant into <br />and including the fol_lowing:_ <br />used for <br />in the permit area. <br />volumes and swell <br />i.
