6.4.5 Exhibit E - Reclamation Plan <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 61 acres. The total area to be fertilized is approximately <br />61 acres. Seeding and fertilizing will be completed after the overburden and <br />topsoil is replaced, smoothed to conform to the existing topography and disked. <br />Optimal periods of seeding are in the fall (after November 1 st) or in the spring <br />from late March up to April 30th. Mulching will not be completed as the quality <br />soils and availability of water should facilitate the rapid establishment of perennial <br />grasses. <br />Following revegetation, weed management strategies will be implemented to <br />facilitate and achieve native grassland. Years 1 thru 5 following revegetation will <br />include an aggressive mowing program to prevent the growth and establishment <br />of weeds, specifically, eight noxious weeds including:.. Canada thistle (Cirsium <br />arvense), Dalmation toadflax (Linaria dalmatica), diffuse knapweed (Centaurea <br />diffusa), leafy spurge (Euphorbia esula), musk thistle (Carduus nutans), Russian <br />knapweed (Centaurea repens), spotted knapweed (Centaurea maculosa) and
