6. Using straw dikes, silt fences, small V -ditches, riprap, mulches, check dams, vegetative <br />sediment filters, temporary cover crops, sediment traps, and other measures that will <br />reduce overland flow velocity, reduce runoff volume, or trap sediment; <br />7. Treating traffic areas with water or dust suppressant to reduce the potential for wind and <br />water erosion. <br />In addition, WFC may utilize appropriate sediment control measures representing the best <br />technology currently available which may include, but not be limited to the following: <br />1. A series of sedimentation ponds; <br />2. Soil surface mechanical manipulation measures that include contour furrowing, chisel <br />plowing, etc.; <br />3. Topographic manipulations that include recontouring or reshaping of graded material in a <br />manner that minimizes the potential for soil erosion; <br />4. Surface protection measures that include surface stabilizers such as temporary cover crop, <br />permanent vegetation covers, or geotextile fabrics, etc.; <br />5. Linear detention and filtering structures that include filter fence, straw bale barrier, brush <br />barrier, and filter berms; <br />6. Measures used in conjunction with overland conveyances including check dams, <br />sediment traps, and water level spreaders; <br />7. Vegetative filters, temporary cover crops, reestablished permanent vegetation covers, etc. <br />All surface mining operations will be conducted to achieve the effluent limitations of 4.05.2(7) <br />for all mixed drainage when it leaves the permit area. Sedimentation ponds or impoundments <br />will be constructed before creating new disturbances, unless approved drainage diversions or <br />other surface water control structures are installed. <br />C. Collection Ditches, Culverts and Diversion Design Parameters <br />The main collection ditches in the original permit area are the 007 East and 007 West Ditch. <br />These have been renamed Ditches C 18 and C 17, respectively. These ditches are used to transport <br />runoff into Sedimentation Pond 007 for treatment in accordance with the requirements of <br />applicable regulations. The location and drainage area of these ditches can be found on Map <br />Page 2.05.3(3)-2 October 2015 (TR -69) <br />
