• Stockpile locations are designated in areas that will restrict erosion from wind and water and <br />additional compaction or contamination. Topsoil for reclamation of ponds and ditches will <br />be hauled by scraper, dozer, and/or front end loader. <br />2.05.4 Reclamation Plan <br />The reclamation objective in the Permit area is to restore the site to approved postmining <br />land uses. This includes restoring the appro~dmate original contours and drainage patterns. <br />In general, the long term usefulness of the area will, at a minimum, be equal to that of the <br />site before mining. <br />The attainment of these objectives will be satisfied by the implementation of the reclamation <br />plan described herein. Kaiser will combine information obtained from baseline sampling <br />activities with current practices in reclamation technology to assure achievement of the <br />reclamation objectives. The general sequence of reclamation operations is described below: <br />(1) Backfilling, grading and contouring <br />(2) Establishment of surface drainage patterns <br />(3) Revegetation and establishment of land to prescribed post-mining land <br />use <br />Generally, backfilling of mined areas has occurred. Final grading of all reclaimed areas will <br />• occur during late summer of 1991. Top soil replacement will take place following final <br />grading, with revegetation scheduled for the fall of 1991. <br />Backfilling, Grading and Contouring <br />Land configurations for final contours are shown on the Post Mining Topography Map, Map <br />9. Post-mining topography will conform approximately to the pre-mining land configuration. <br />Based on aerial photography and ground surveys of the Chimney Rock Mine site, a 1" _ <br />100' topography map was developed to accurately depict the state of mining and reclamation <br />activities (Map 9, Post Mining Topography). Maps 10A, lOB and lOC, Post Mining <br />Topography Cross Sections depict the mine topography in its present state with the amended <br />post mining slopes being much less steep than those originally approved and will provide a <br />less erosional land form. <br />To further prevent erosion on the slopes, terracing will be employed as part of the final <br />grading effort. The terraces have been designed in a broad, flat trapezoidal shape as shown <br />on Figure 4, Typical Terrace Cross-Section, with a constant 1 percent slope following post <br />mine contours (Map 9, Pogt Mine Topography). It should be noted that final grading will <br />take place using bull dozers. The dozers will shape the terrain so as to leave a nonuniform <br />slope. Small depressions and high spots will be left so as to allow for infiltration and <br />vegetation reestablishment. However, these will be shaped so as to not interfere with <br />• 2.05-4 <br />
