Fertilizer <br />6.4.5 Exhibit E — Reclamation Plan <br />Table 6.4.5 -4 Recommended Seed Mixture <br />Species (Variety) <br />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 />Diammonium phosphate (18 -46 -0) 250 <br />(46 -53% available P2O5 with 18 -21 % <br />N) <br />Standard rate <br />Ibs /acre <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 <br />be completed as the quality soils and availability of water should facilitate the <br />rapid establishment of perennial 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 <br />Yellow toadflax (Linaria vulgaris) as mandated by Colorado State Law (35- <br />5.5CRS1990, 1996). If needed, herbicide application will be applied as needed <br />to further control these weeds. Herbicides will also be used to control salt cedar <br />Turnpike Mining Resource M- 2004 - 009 -AM -2 <br />Regular 112 Amendment <br />
