<br />Coulson Excavating Company, Inc. - Bonser Gravel Pit <br />Exhibit E -Reclamation Plan <br />Fertilizer will not be used near the edge of ponds because of the possibility of nitrate contamination of the <br />pond water. The total area to be seeded is approximately 70 acres. The total area to be fertilized is 70 <br />acres. Seeding and fertilizing will be completed after the overburden and topsoil is replaced, smoothed to <br />conform to the existing topography, and disked. Optimal periods of seeding are in the fall (after <br />November Lst) or in the spring from late March up to April 30th. Mulching will not be completed as the <br />quality soils and availability of water should facilitate the rapid establishment of perennial grasses. <br />Following revegetation, weed management strategies will be implemented to facilitate and achieve native <br />grassland. The strategies will include an aggressive mowing program to prevent the growth and <br />establishment of weeds, specifically, the eight noxious weeds recognized by Larinter County: Canada <br />thistle (Cirsium arvense), Dalmation toadflax (Linario dalmatica), diffuse knapweed (Centaurea dilJirsa), <br />leafy spurge (Euphorbia esula), musk thistle (Carduus Hurons), Russian knapweed (Centaurea repens), <br />spotted knapweed (Centaurea maculosa), and Yellow toadflax (Linaria vulgaris) az mandated by <br />Colorado State Law (35-S.SCRS1990, ]996). <br />Total Cost <br />hr summary, the total costs for this reclamation plan include: <br />• Disking $60.00-$80.00/ac <br />• Seeding $40,390 to $.16,546 (for 70 ac) <br />• Fertilizing $9,625 (for 70 ac) <br />Alternative Reclamation Plan <br />There is no alternative reclamation plan. <br />References <br />Benson, C.H., and G.P.
