1 1 1 1 1 1 1 1 1 where soil was not stockpiled. Also, since the minimum Yanks Gulch Project life is estimated to be thirty years, it is impossible to detemrine what the adjacent postmining land uses will be and how best to reclaim the facilities area to enhance adjacent property values and to wmpliment their uses. When the reclamation plan is prepared it will follow the general sequence detailed above. The reclamation of the Piceance Site facility will proceed similarly to that previously described. The main differences will be that the scale of disturbance will be much smaller, and unlike dte Well Feld mine panels, this facility area will be pertrtanent and it will not periodically relocate across the project surface. It is anticipated that the evaporation pond at the Piceance facility will be reclaiated using one of two potential methods. The residual in the bottom of the pond would be tested at closure. Depending upon their nature these materials would then either be hauled to a landfill for disposal (including the liner) or the liner would be ripped, the site wvered and revegetated. 5.1.1 Backfilling and Grading Grading operations will return areas to approximate original topography to the extent this is physically and operationally possible. FII materials will be graded back into cuts. The interface between undisturbed and disturbed areas will be feathered to create a smooth transition to the extent this is possible. Grading will establish positive drainage and provide adequate reconstructed channels to ensure that runoff is safely passed though and off of dte disturbed area (see Section 3.0). Roads, access routes and other areas that are excessively compacted will be ripped or otherwise loosened to promote plant growth. The graded surface will be scarified and roughened to avoid the creation of slippage planes between the subsoil and topdressing materials. Terraces and other erosion and sediment control stmctures that require placement and construction will be constructed during grading operations and prior to soil reconsWCtion. To the fullest extent physically possible, final surface manipulations during grading operations will proceed along the contour in an effort to minimize features that might promote surface or subsurface erosion or instability (Fgure 13). 5.1.2 Soil Reconstruction Soil reconstruction involves the redistribution and selective placement of soil reconstruction materials, the application of materials or performance of practices that promote surface stabilization, and the analysis of soil fertility and timely application of appropriate soil amendments that promote the establishment and growth of a permanent, diverse vegetation community capable of supporting the postmining land use. After final backfilling and grading has recontoured a site to its final topography, soil reconstruction materials will be distributed. Soils used in reconstruction will be direct hauled from salvage areas and immediately redistributed or "live handled" whenever this is physically possible. Livehandling provides a number of benefits including maximizing the potential for volunteer growth from residual plant materials and the retention of viable soil microbial populations. live handling also minimizes soil handling and reduces soil management costs. Reconstructed soil thickness for a given area will be determined by the original volume of ' suitable soil available for salvage, the type of reconstruction material used and the growth requirements of the vegetation community to be established. Normally, deeper soils with better moisture characteristics and less rock will be used for establishing communities that are ' primarily herbaceous, while soils that are well drained and rockier are better suited for establishing vegetation communities with greater percentages of woody plant species. Topdressing for a particular vegetation community type will be redistributed across the entire ' Americm Soda. LL.P.
