that it will receive flow from contributing areas, and transport them safely down the face of the <br /> Sutey Pile to Ditch 1. <br /> Upper Ditch 8 <br /> The upper portion of Ditch 8 is 200 feet in length, and shall be trapezoidal in shape, having a <br /> depth, upon completion of two feet (2'). The base of the channel shall be five feet (5') wide, with <br /> side slopes being 2H:1V. The channel shall be over excavated so that these dimensions are <br /> accomplished upon completion of the ditch. <br /> Upon completion and acceptance of excavation, three inches (3") of topsoil will be uniformly <br /> distributed on the base and sides of the channel. The topsoil will be derived from the topsoil <br /> stockpile located to the west of the Sutey Refuse Pile. In order to achieve successful application <br /> of the liner specified below, it will be necessary to remove surface irregularities and clods and <br /> rock from the surface of the soil. A flat, uniform, rock- and dip -free soil surface must be <br /> established prior to'seed and fertilizer application. The seed and fertilizer may not be applied <br /> until such a surface has been created. <br /> Upon completion of topsoiling, diammonium phosphate fertilizer(18-46-0) shall be applied to the <br /> at a rate of 300 pounds per acre. Seed, to be provided by PROJECT MANAGER, will be applied <br /> at the rate of ten pounds (10#) per acre. <br /> After seeding and fertilization is complete, a liner shall be installed. The liner shall consist of <br /> 100% coconut fiber encased top and bottom in heavyweight ultra violet stabilized netting. <br /> Components shall be sewn on 1.5 inch centers. North American Green 125 or approved <br /> equivalent is acceptable. The liner shall be installed per manufacturers specifications. <br /> Lower Ditch 8 <br /> The lower portion of Ditch 8 is approximately 600 Feet long, and will be relocated to the east of <br /> its present location. The western most margin of the new ditch shall be located ten feet (10') <br /> east of the eastern most margin of the existing channel. Upon completion of installation, the <br /> upper and lower portions of Ditch 8 will transition into one ditch. <br /> NOTE that the liner specified below must extend four feet (4') beyond the crest of Ditch 8 on <br /> each side. The specifications for liner installation, including soil application, for the four feet (4') <br /> side-of-channel application area are identical to those for installation within the channel, except <br /> that prior to beginning installation, the ground surface will be ripped to a minimum depth of eight <br /> inches (8") on no less than thirty inch (30") centers. Ripping shall occur perpendicular to the fall <br /> of the slope. These channel margins will be seeded with seed provided by PROJECT <br /> MANAGER at the rate specified in Table 1, Mine Site Seed. <br /> The lower portion of Ditch 8 will be trapezoidal in shape, having a bottom width of not less than <br /> five feet (5'). Minimum depth shall be two feet (2'). Side walls shall be no steeper than 2.5H:1 V. <br /> Topsoil, derived from the topsoil stockpile located to the west of the Sutey Refuse pile, will be <br /> evenly applied to the channel at a two inch (2") depth. In order to achieve successful application <br /> of the liner, specified below, it will be necessary to remove clods and rock from the surface of the <br /> soil. A flat, uniformly rock- and dip- free soil surface must be established prior to installation of <br /> the lower liner, in order to ensure a positive contact between the soil surface and the liner. The <br /> mat shall consist of a two layer system. The lower liner shall by non-woven textile fabric which <br /> will not inhibit vegetative growth. The upper liner shall consist of an excelsior liner containing <br /> 15 <br />
