EXHIBIT E — RECLAMATION PLAN
<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 area to be seeded is
<br />approximately 25 acres. The total area to be fertilized is approximately 25 acres.
<br />Seeding and fertilizing will be completed after the overburden and topsoil is
<br />replaced, smoothed to conform to the existing topography and disked. Optimal
<br />periods of seeding are in the fall (after November 1st) or in the spring from late
<br />March up to April 30th. Mulching will not be completed as the quality soils and
<br />availability of water should facilitate the 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 recognized by Larimer County:
<br />Canada thistle (Cirsium arvense), Dalmation toadflax (Linaria dalmatica), diffuse
<br />knapweed (Centaurea diffusa), leafy spurge (Euphorbia esula), musk thistle
<br />(Carduus nutans), Russian knapweed (Centaurea repens), spotted knapweed
<br />(Centaurea maculosa) and Yellow toadflax (Linaria vulgaris) as mandated by
<br />Colorado State Law (35- 5.5CRS1990, 1996).
<br />ALTERNATIVE RECLAMATION PLAN
<br />There is no alternative reclamation plan at this time
