6.4.5 Exhibit E -Reclamation Plan <br />Table 6.4.5. Fertilizer Application <br />Fertilizer Standard rate <br />Ibs/acre <br />Diammonium phosphate (18-46-0) 250 <br />(46-53% available P205with 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 148 acres. The total area to be fertilized is <br />approximately 148 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, the eight noxious weeds including: Canada thistle <br />(Cirsium arvense), Dalmation toadflax (Linaria dalmatica), diffuse knapweed <br />(Centaurea diffusa), leafy spurge (Euphorbia esula), musk thistle (Carduus <br />nutans), Russian knapweed (Centaurea repens), spotted knapweed (Centaurea <br />maculosa) and Yellow toadflax (Linaria vulgaris) as mandated by Colorado State <br />Law (35-5.5CRS1990, 1996). If needed, herbicide application will be applied as <br />needed to further control these weeds. Herbicides will also be used to control <br />salt cedar (Tamarix spp.) if it becomes established in the reclaimed area. Table <br />6 presents recommended herbicides, application rate, and time of application for <br />each of the 9 species. It may be necessary to replant treated areas. <br />Table 6.4.5-6.
