Excavation Company Inc. -Stroh Gravel Pit Exhibit E -Reclamation Plan Table 3 Fertilizer Standard Costs/Pound Cost/Acre Total Costs rate lbs/acre based on a bulk rate of $327.00/ton (for 43 ac) Diammoniumphosphate 250 $0.55 $137.50 $5,912.50 (18-46-0) (46-53% available PzOs with 18- 21% N) ~ Fertilizer will not be used near the edge of the pond, since the possibility of nitrate contamination in the pond water exists. The total area to be seeded is approximately 43 acres. The total area to be fertilized is approximately 43 acres. Seeding and fertilizing will be completed after the overburden and topsoil is replaced, smoothed to conform to the existing topography and disked. Optimal periods of seeding are in the fall (after November 1st) or in the spring from late March up to Apri130th. Mulching will not be completed as the quality soils and availability of water should facilitate the rapid establishment of perennial grasses. Following revegetation, weed management strategies will be implemented to facilitate and achieve native grassland. Years 1 thru 5 following revegetation will include an aggressive mowing program to prevent the growth and establishment of weeds, specifically, the eight noxious weeds recognized by Larimer County: Canada thistle (Cirstum arvense), Dalmation toadflax (Linaria dalmatica), diffuse knapweed (Centaurea diffusa), leafy spurge (Euphorbia esula), musk thistle (Carduus nutans), Russian knapweed (Centaurea repens), spotted knapweed (Centaurea maculosa) and Yellow toadflax (Linaria vulgaris) as mandated by Colorado State Law (35-S.SCRS1990, 1996). Alternative Reclamation Plan There is no alternative reclamation plan. References Benson, C.H., and G.P.
