6.4.5 Exhibit E -Reclamation Plan <br />Based on this seed mixture, an application rate of approximately 9.5 Ibs PLS/ac <br />will be used. Topsoil should be disked prior to seeding. A standard application <br />of a fertilizer will be used and applied at a rate of 250 Ibs/ac. Fertilizer will not be <br />used near the edge of any water storage areas or the pond, to avoid the <br />possibility of nitrate contamination of the water. <br />The total area to be seeded and fertilized is approximately 48 acres - 31 acres in <br />Phase I and 17 acres in Phase II. Seeding and fertilizing will be completed after <br />the 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 />nufans), 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 />saltecedar (Tamarix spp.) if it becomes established in the reclaimed area. Table <br />6.4.5-5 presents recommended herbicides, application rate, and time of <br />application for each of the 9 species. It may be necessary to replant treated <br />areas. <br />November 16, 2006 Bokelman/Walters Pit <br />Page 11 of 36 Regular 112 Permit Application <br />
