. f. Using straw dikes, silt fences, small ditches, riprap, mulches, check dams, <br />vegetative sediment filters, temporary cover crops, sediment traps, and other <br />measures that will reduce overland flow velocity, reduce runoff volume, or trap <br />sediment; <br />g. Treating traffic areas with water or dust suppressant to reduce the potential forwind <br />and water erosion. - <br />h. Soil surface mechanical manipulation measures that include contour furrowing, <br />chisel plowing, etc.; <br />i. Topographic manipulations that include recontouring or reshaping of graded <br />material in a manner that minimizes the potential for soil erosion; <br />j. Surface protection measures that include surface stabilizers such as temporary <br />cover crop, permanent vegetation covers, or geotextile fabrics, etc.; <br />k. Linear detention and filtering structures that include filter fence, straw bale barrier, <br />• brush barrier, and filter berms; <br />I. Measures used in conjunction with overland conveyances including check dams, <br />sediment traps, and water level spreaders; <br />m. Vegetative filters, temporary cover crops, reestablished permanent vegetation <br />covers, etc. <br />All surface mining operations will be conducted to achieve the effluent limitations of 4.05.27(7) for <br />all mixed drainage when it leaves the permit area. <br />Sedimentation ponds or impoundments will be constructed before creating new disturbances, <br />unless approved drainage diversions or other surface water control structures are installed. <br />3) Sedimentation Ponds 008 through 013 Design Parameters <br />In accordance with 4.05.2 and NPDES regulations, WFC will use Ponds 008 through 013 to <br />prevent, to the extent possible, additional contributions of sediment to stream flow or runoff outside <br />the permit area due to mining disturbance. All amendment pond designs are found later in this <br />• section. <br />(Revised ivo~l Attachment 2.05.3(3) -10-2 <br />
