6.4.5 Exhibit E - Reclamation Plan <br />Interior haul roads will be ripped, graded, and surface soiled in preparation for <br />revegetation. <br />Seeding and Fertilizing <br />Currently, shortgrass prairie is the dominant plant species. At present, the area is <br />grazed all year around. Cover in the pasture is sparse all year as a result of the <br />continuous grazing of cattle. <br />The proposed seeding areas are shown on Exhibit F - Reclamation Plan Map. <br />The recommended seeding method is by drill and seeding rates assume this <br />method. The species composition of the seed mixture recommended for <br />reclamation is shown in Table 6.4.5-4 below. <br />Table 6.4.5-4 Recommended Seed Mixture <br />Species (Variety) Rate - pure live Native/ W/C <br /> seed (PLS) Introduced Season <br /> Ibs/ac <br />Thickspike wheatgrass 8.0 to 10.0 Native Cool <br />(Critana) <br />Sideoats grama (Vaughn) 5.0 to 7.0 Native Warm <br />Switchgrass (Nebraska-28) 4.0 to 6.0 Native Warm <br />Alfalfa (Nomad) 3.0 to 5.0 Introduced NA <br />TOTAL 20.0 to 28.0 <br />Based on this seed mixture, an application rate of approximately 20.0 to 28.0 Ibs <br />PLS/ac will be used. Topsoil should be disked prior to seeding. It is <br />recommended that fertilizer be utilized for reclamation. A standard application of <br />fertilizer will be used and applied at a rate of 250 Ibs/ac as shown in Table 6.4.5- <br />5. <br />table 6.4.5-5. Fertilizer Application <br />Fertilizer Standard rate <br />Ibs/acre <br />Diammonium phosphate (18-46-0) 250 <br />(46-53% available P2O5 with 18-21 % <br />N) <br />Fertilizer will not be used near the edge of the pond, since the possibility of <br />nitrate contamination in the pond water exists. The total disturbed area to be <br />seeded is approximately 138 acres. The total area to be fertilized is <br />approximately 138 acres. Seeding and fertilizing will be completed after the <br />overburden and topsoil is replaced, smoothed to conform to the existing <br />topography and disked. Optimal periods of seeding are in the fall (after <br />November 1st) or in the spring from late March up to April 30th. Mulching will not
