The final surface as shown on the Post-mining Topography Map (Map <br />19) will approximate the overall pre-mining grades. Appropriate <br />cross sections that show the anticipated final surface configura- <br />tion of the proposed permit area, in conjunction with the existing <br />pre-mining topography, are shown on the Pre-mining and Post-mining <br />Cross Section (Map 20). <br />This final surface configuration also reflects an often neglected <br />concept of providing topographic relief for wildlife habitat. The <br />regrading plan reestablishes escape cover, south facing slopes for <br />wintering big game populations and small drainages suitable as <br />future location of stockponds necessary to achieve the post-mining <br />land use. <br />Colowyo has prepared this reclamation plan with the understanding <br />that some aspects of current reclamation practices are still in the <br />development stages. Therefore, a degree of flexibility has been <br />provided to allow changes and modification as techniques are <br />refined or expanded. Colowyo will continue to evaluate the results <br />of its reclamation plan each year in consultation with the Division <br />and take advantage of each opportunity to try new plant species and <br />• materials and new methods for seeding and erosion control. <br />Topsoil Redistribution Plan <br />Prior to any mining-related disturbances, all available topsoil <br />will be removed from the site to be disturbed as discussed in <br />Section 2.05.3, and will be redistributed or stockpiled as <br />necessary to satisfy the needs of the reclamation timetable as <br />described herein. <br />Final grading before topsoil placement will be conducted in a <br />manner that minimizes erosion and provides a surface for the <br />topsoil that minimizes slippage. If spoil compaction is a problem, <br />the spoil will be ripped with a dozer to minimize compaction, <br />assure stability and minimize slippage after topsoil replacement. <br />Topsoil will then be redistributed and graded to a minimum depth of <br />eighteen inches (twelve inches in Section 11). Topsoil may be <br />applied at depths greater than 18 inches in selected areas where <br />plants, that may require a deep soil, will be established in <br />conjunction with the proposed post- mining land use. Topsoil will <br />2.05-41 <br />
