Assuming that water is pumped for eight hours per day, five days a week, for 50 weeks each <br />year, approximately 54.5 ac -ft would be removed from the Yampa River alluvium on an annual <br />basis. This is an extreme pumping scenario since water usage at the loadout consists only of <br />bathhouse consumption, dust suppression, and wash -down water. <br />Consumptive use at the sediment ponds is calculated on the basis of lake evaporation. <br />Estimated annual evaporation from the pond water surface is 1.9 acre feet. Table 21-1 shows <br />the derivation of this figure. This figure is a worst-case estimate because it assumes the ponds <br />are always full. <br />HGTI paid a one-time depletion charge to mitigate potential impacts and support recovery <br />activities for the endangered fishes to the National Fish and Wildlife Foundation in September, <br />1997. <br />The previously outlined procedures will be implemented to minimize disturbances and adverse <br />impacts on fish and wildlife and related environmental values during and after operation of the <br />Loadout facility. Enhancement of these resources will be achieved following reclamation of the <br />facility by restoring the approximate original contour of the land, removal of all structures and <br />barriers (fences and rail lines), and timely revegetation with species compatible with the post - <br />operational land use. Displaced species which have the capacity to exploit the habitat created by <br />reclamation activities will utilize developing reclaimed areas. <br />Additional enhancement activities are considered to be infeasible or impractical due to the limited size <br />of the disturbance area, its configuration, and surrounding land use activities. <br />Literature Cited <br />Avian Power Line Interaction Committee (APLIC), 1994.
