Rule 2: Permits <br />• Stripped topsoil and usable subsoil will be promptly redistributed on regraded areas <br />where possible. In all other areas, this material will be stockpiled. Topsoil stockpiles <br />will be located as shown on Map 2.05.3-2. These locations have been chosen to <br />minimize soil transport distances, maximize stability of the stockpiles, and avoid <br />disturbance by mining operations. They will be protected from wind and water erosion, <br />unnecessary compaction, and contamination. If sedimentation pond topsoil piles cannot <br />be constructed within an existing pond drainage area, berms will be constructed along the <br />downhill side to hold 100% of the 10-year, 24-hour storm event. Runoff from stockpiles <br />will be contained and treated using silt fences, gravel filters, or straw bales. Stockpiles <br />will be constructed in an oval shape with the top leveled. They will be identified with <br />signage. Each pile will be seeded with an approved mix of non-noxious, quick-growing <br />annual and perennial plants during the first appropriate growing season. <br />TABLE 2.05:3=2a. <br />CQRENCITO CANYON°MINE <br />TOPSOIL STOCKPILE VOLUMES <br />• <br />Stockpile Volume <br />(loose cubic yards)5 <br />Jeff Canyon Surface' 325,000 <br />Lorencito Canyon Surface Minez 310,000 <br />Loadout3 31,000 <br />Roads° 12,000 <br />TOTAL 678,000 <br />'Approximately 105 Acres at 1.6' <br />ZApproximately 100 acres at 1.6' <br />3Approximately 4 acres at 4.0' <br />°As LCC expects to use existing roads, minimal topsoil from roads is expected. <br />SSwell =20°J° <br />• <br />Topsoil stockpiles will be surveyed when established and annually thereafter, as needed. <br />Volumes will be updated and reported annually as part of the annual reclamation report. <br />2.05-33b (Revised 9/30/03) <br />
