The location, configuration, and components of the 6MN Mine Water Storage Reservoir installation are shown on <br /> Map 24 (sheet 2 of 3), Surface Facilities and Freshwater Systems. Related design information is provided in <br /> Exhibits 8CC, 6MN Mine Water Storage Reservoir — Drainage Design, and 490, 6MN Mine Water Storage <br /> Reservoir— Design Drawings, including a design stability analysis for the pond embankment (also refer to detailed <br /> Reservoir description on pages 2.05-45.6f through 2.05-45.8). Because the proposed Reservoir storage volume is <br /> greater than 20 acre-feet, design and compliance documentation have also been submitted to the Mine Safety and <br /> Health Administration (MSHA) for review and approval. <br /> SMALL AREA EXEMPTIONS AND ALTERNATIVE SEDIMENT CONTROLS <br /> TCC has been granted several Small Area Exemptions (SAE's) and/or approvals to utilize Alternative Sedimant <br /> Controls (ASC's) within the permit area. Effective drainage and sedimentation control in these areas will be <br /> achieved through the use of a number of individual or combined methods, including gravel-surfacing; erosion <br /> control fabric or materials; berms; contour furrows; sediment traps; rock check dams; vegetative filters; the use of <br /> silt fences, straw wattles, or straw bales; or other approved methods. Specific SAE/ASC practices are described in <br /> the following sections. <br /> RN 17-07 2.05-82.1 02/15/18 <br />
