In <br />this comparison we are interested in the sediment generated from the reclaimed site above <br />such structures, as if they had been removed. Likewise, for the undisturbed azea, there aze <br />no such controls. Therefore, for the purposes of our comparison, a value of unity (one) <br />will be assigned this factor, rendering no nnpact to our calculations. <br />p.9 <br />Coors Energy Compare/ Keenesburg Mine Page 6 <br />Phase II Band Release 5edlmerrtobgy Demonstration <br />
