Table 2—NRCS Seed Mix for Thomas Pit#4 <br /> Pounds Pure Live <br /> Species Seed/Acre <br /> Sand Bluestem Elinda 6.00 <br /> Big Bluestem (Kaw) 1.65 <br /> Yellow Indian Grass (Llano) 3.30 <br /> Switchgrass (Grenville) 1.50 <br /> Prairie Sandreed (Goshen) 1.50 <br /> Little Bluestem (Pastura) 1.05 <br /> Total 15.00 <br /> ITEM 8.1 — MINE PIT FLOOR SEEDING & REVEGETATION <br /> Following earthwork activities, the CONTRACTOR shall seed and mulch the mine pit floor and all areas <br /> disturbed by reclamation activities. The specified seed and indicated amounts of the mixture shall be <br /> uniformly drilled over all prepared ground areas in a manner that will produce an even stand of grass <br /> over the entire area seeded. Seed shall be drilled using a rangeland seed drill, unless otherwise <br /> approved by the PROJECT MANAGER. It is estimated that six acres (6 ac) will be reseeded by <br /> seed drilling. <br /> The following requirements apply to reseeding the mine pit floor: <br /> A. Seed Distribution: The rangeland drill will be pulled at a speed not to exceed 4 mph. The seed <br /> shall be drilled and covered to a depth not less than inch or more than 3/4 inch. The drill rows <br /> shall be spaced a minimum of 10 inches apart. The seed drill shall be calibrated to achieve <br /> seeding rates of 15 pls Ibs/acre. <br /> B. Fertilizer: No fertilizer is required. <br /> C. Mulch: Vegetative Mulching shall be done within the same day as seeding. Mulch shall be <br /> spread uniformly in a continuous blanket over the seeded areas using two tons (4,000 Ibs) of <br /> certified weed-free material per acre. Weed-free certificates must be furnished to <br /> the PROJECT MANAGER. The mulch shall be spread in such a manner as to prevent <br /> bunching. <br /> D. Securing Mulch: Immediately following the spreading of the mulch, the material shall be <br /> anchored securely into the soil a minimum of 3 inches by means of a mulch anchoring machine <br /> equipped with large coulter-type discs spaced on approximate 8-inch centers. Edges of the discs <br /> shall be dull to prevent cutting of the mulch material. In areas where equipment cannot be used, <br /> mulch shall be secured by a shallow covering of earth or by embedding with approved hand <br /> methods, including a straight blade spade with a dulled edge. <br /> E. Watering: No water will be applied to the revegetated areas. <br /> Page 14 of 16 <br />
