Rule 2: Permits After Ute cut tlvough the ridge is completed, a cross ridge operation is established. A contour cut r on the lowest • seam to be mined is kept 300 feet in advance of the main pit area. The material from the contour cut is pushed or hauled into adjacent fills. A solid 15-foot wide berm four feel high is left along the outcrop to keep material from going down slope in areas where overburden will not be placed above fills. Alter the contour cut is established on both sides of Ute ridge, cuts are taken down the center of the ridge on the exposed coal seams. The material from these cuts will be pushed, hauled, or cast into the open pit areas in the center of [he ridge. This material is graded to meet final reclamation contours and covered with topsoil or suitable material This sequencing minimizes We need for topsoil storage and re-handling. Topsoil or other suitable material are hauled or pushed from its original location to the graded areas during the mining cycle. Except for the initial cut through Ute ridge, the outslopes and pit areas are graded [o final contours within 1,500 ft of the active pi[ area except as noted. Coal is removed as i[ is exposed and hauled frmn Ute pits. Shale and other extraneous material separated from the coal prior to loading are left in the pit or placed with the overburden. Sediment structures aze built in advance of brush removal prior to the outcrop cut for Ure proper control of sediment. The mining operation proceeds southwest wiUt We ridge. As fills are encountered, they are filled with material adjacent to Utem. The cross ridge opemuon continues until economics dictate a transition to contour Honing. Contour mining operations will be similar to area mining, except mining will follow the coal outcrop and create a highwall of only 50 to 80 feet, similar to a roadcu[. After initial startup cuts are completed, mining will be doue in a haul-back method to allow current reclamation of mined-out areas. Coal will be hauled on roads within Ure active mining areas and Ute main haul roads are to be constructed on existing roads. Fill Construction . All vegetation is removed from the area covered by the fill and the adjacent spoil transportation zones. The vegetation is burned or removed from [he property if it has economic value. Topsoil stripping, salvaging, and replacement occur in accordance with the plan described on pages 2.05- 33 and 2.05-35. A contour cut is taken on any coal seams encountered wittin the fill boundary and Ute coal removed. The material from this cut is placed in the fill. Overburden form the mining operation is placed in horizontal lifts with dozers in the bottom of the till. Large rocks are sepaza[ed from [he fill and worked with a dozer [o consWct a rock drain. This drain runs from the toe to the outcrop of the lowest coal seam mined. The remaining overburden is used [o bring the fill to its designed profile and elevation. Design criteria for the fills are provided in Exhibit 13. r L 2.05-10 (Revised 06/15/03)
