<br />• Reject material and process Cincs will be used in [he reconstruction of an acceptable plant <br />grow[It medium. These materials will be subjected to physical and chemical soil analysts to <br />dctcrntining their use for supporting plant growth. Soil analyses will include pH, texture, <br />conductivity, sodium adsorption ratio, nitrate nitrogen, plan[ available phosphorous and <br />potassium. <br />SEDIAfENT CONTROL <br />The operation has been designed such that there will be no discharge to surface drainages. <br />Diversion ditches and berms will prevent off-site discharge into the natural drainage system. <br />Runoff on the property will be directed to the pit floor from where it may be diverted to the <br />settling ponds for recycling as process water. <br />REGRADING AND SHAPING <br />Pit slopes and the pit floor will be backfilled and/or graded to achieve the final contour and <br />in preparation for topsoil placement. Contour furrows or water bars will be established on the <br />pit slopes to reduce erosion. Plant reject material and process fines will be used as reclamation <br />backfill. <br />TOPSOIL REPLACEMENT <br />• Topsoil replacement will occur following regrading and scarification of the surface of <br />backfilled material, primarily in late summer and fall. This procedure limits the time that <br />topsoil is exposed prior to revegetation and avoids moving topsoil when it is frozen or too wet. <br />After reject material and fines are in place they will be treated with organic and inorganic <br />amendments as necessary (based on the soil test results). Following this treatment the <br />backfilled surface will be ripped to incorporate the amendments. Topsoil will then be spread <br />on the prepared surface. Topsoil material will provide seed and plant parts and soil microbes <br />for nutrients. <br />REVEGETATION SPECIES <br />Grass and shrub species and seed rates to be used Cor revegetation arc: <br />Ibs PLS/acre <br />- Western Wheatgrass 6.0 <br />- Thickspike Wheatgrass 3.0 <br />- Little Bluestem 2.0 <br />- Green Needlegrass 2.0 <br />- Fringed Sagebrush 0.1 <br />n <br />U <br />
