Coulson Excavation Company Inc. -Stroh Gravel Pit <br />Exhibit E -Reclamation Plan <br />Table 3 <br />Total Costs <br />rate Ibs/acre based on a bulk <br />rate of $327.00/ton (for 43 ac) <br />(18-46-0) (46-53% <br />available PzOS with 18- <br />21%N) <br />Fertilizer will not be used near the edge of the pond, since the possibility of nitrate contamination <br />in the pond water exists. The total area to be seeded is approximately 43 acres. The total area to <br />be fertilized is approximately 43 acres. Seeding and fertilizing will be completed after the <br />overburden and topsoil is replaced, smoothed to conform to the existing topography and disked. <br />Optimal periods of seeding are in the fall (after November 1st) or in the spring from late March <br />up to Apri130th. Mulching will not be completed as the quality soils and availability of water <br />should facilitate the rapid establishment of perennial grasses. <br />Following revegetation, weed management strategies will be implemented to facilitate and <br />achieve native grassland. Yeazs 1 thru 5 following revegetation will include an aggressive <br />mowing program to prevent the growth and establishment of weeds, specifically, the eight <br />noxious weeds recognized by Larimer County: Canada thistle (Cirsium arvense), Dalmation <br />toadflax (Linaria dalmatica), diffuse knapweed (Centaurea diffusa), leafy spurge (Euphorbia <br />esula), musk thistle (Carduus nutans), Russian knapweed (Centaurea repens), spotted knapweed <br />(Centaurea maculosa) and Yellow toadflax (Linaria vulgaris) as mandated by Colorado State <br />Law (35-S.SCRS1990, 1996). <br />Alternative Reclamation Plan <br />There is no alternative reclamation plan. <br />References <br />Benson, C.H., and G.P.
