eh ESPEY, NUSTON 8 ASSOCIATES, INC. r~ L J sagebrush in the valley bottom. A moist meadow community exists adjacent to Curtis Creek which contains sedges, rushes, and grass. It is anticipated that through proper reclamation planning that the mountain brush community can be reestablished on the embankments of the refuse waste disposal pile with grassland communities established on the flat refuse pile top, roadbed, sedimentation pond, and stockpile storage areas. By reestablishing these communities the postmining land use will essentially remain the same as currently exists and the land can be returned to livestock grazing and wildlife habitat. 13.5.2 Topography A topographic map depicting the final surface topographic configuration • of the refuse disposal area is presented in Fig. 13.1.4. The premining topography, shown on Fig. 13.1.2, is characterized by a relatively level surface adjacent to Curtis Creek; slopes of approximately 12 percent in the valley bottom on the southern portion of the mine plan azea; and slopes greater than 35 percent on the northern portion of the mine plan area. The area adjacent to Curtic Creek will not be disturbed so no topographic alteration will be made. The postmining configura- tion of the valley bottom where the haul road, sedimentation pond, and topsoil stockpiles are established will be reestablished to conform to premining conditions. Because the refuse disposal pile will be a permanent feature, alteration of the premining topographic surface will occur. With the addition of approximately 79,000 tons of waste mine rock, the area will be filled to elevation creating embankment slopes of 4h:ly with a roughly flat top surface tieing into the steep slopes on the northern and eastern portion of the mine plan area. Retopsoiling and revegetation will follow active filling, as soon as practical, when lifts have been established on the refuse pile. u 13-18
