(f) to revegetate the allvuial well field access road topsoil stock- <br />pile as soon as practicable and maintenance of a collector ditch <br />and berm at the base of the piles to trap sediment until this <br />revegetation is accomplished. <br />G. Summary of Compliance <br />If the proposed stipulations are implemented, this section will comply. <br />H. Proposed Departmental Action <br />To approve, with stipulations, the applicants' plan to protect the hydrologic <br />balance in the mine plan area. <br />I. Alternatives to the Proposed Action <br />There are several alternatives to the applicants' proposal for surface water <br />control and reclamation at the proposed permit and mine plan area. <br />Sediment control measures could be modified to include sedimentation ponds in <br />the channels of Scullion Gulch and the Red Wash tributary, which receives <br />run-off from the Refuse Disposal area. In this manner, all run-off draining <br />through the permit area would be treated for sediment load and monitored at <br />each discharge into the natural drainage system. This is a simple and <br />practically fool-proof method of run-off control, but the ponds required under <br />such a plan would be disproportionately large. A much greater drainage area <br />would contribute to such ponds than that which will drain into the ponds as <br />proposed. It is for this reason that the applicant declined to construct a <br />large sediment pond in Scullion Gulch downstream of the D-Portal area to <br />control run-off during reclamation. <br />J. Environmental Impacts of the Operation <br />Impacts to the- hydrologic balance will occur as a result of the proposed <br />mine.Short term impacts which will occur as a result of surface facilities <br />appurtenant to the underground mine include reduction of water yield from the <br />31 <br />
