<br /> <br />before the falcon returns to the nest site no adverse consequences <br />are expected. This special lease stipulation will provide the same <br />protection as the original unsuitability determination. <br />Any rights-of-way that may exist will be protected by making the lease <br />subject to all valid rights existing on the date issued. <br />Undiscovered cultural resources can be mitigated by requiring the <br />lessee to notify the authorised officer if any are discovered during <br />operations under this lease. <br />The salt load to Foidel Creek is expected to increase as a result of <br />this alternative, however the actual increase will be insignificant. <br /> Shallow aquifers in the overburden would be removed in the lowermost <br /> portion of the <br />its but are replaced with a more permeable spoil <br /> p <br /> aquifer after mining is completed. Those parts of the coal and <br />overlying aquifers that were removed by surface mining would be <br />replaced by a single aquifer comprised of broken spoil materials. <br />Because of the sandstone in the coal-bearing formations in both <br />Wyoming and Colorado, the spoil materials should be moderately <br />permeable unless they were compacted during final placement. All <br />replaced spoil aquifers, therefore, should have at least as much <br />capacity to store and transmit groundwater as the original aquifers, <br />once they are tesaturated. However, resaturation could take 50 to 100 <br />years after completion of mining. ' <br />. Impacts to soils, vegetation, air and water quality, visual resources, <br />8 <br />
