D-Seam on water quality within the mine. <br />C. Evaluation of Compliance <br />Acid-Forming and Toxic-Forming Sooil <br />The only material which could be considered spoil in the mine plan area is the <br />fill material used in the construction of surface facilities. The applicant <br />analyzed composite samples of the fill material which were composed of the <br />Upper and Lower Williams Fork Formations. None of this material is considered <br />acid or toxic-forming and no detrimental ground water impacts are expected. <br />The applicant is in compliance. <br />Mine Discharges <br />There are expected to be no discharges of ground water from the proposed mining <br />operation except to the head tank for storage and eventual use. Ground water <br />inflows are expected to be less than usage of the water for dust suppression <br />and storage capacity of material in the mine. <br />It is not certain if discharge of water through the portal areas is possible <br />subsequent to mining. The applicant has, however, proposed backfilling of the <br />portals and construction of concrete bulk heads to minimize possible <br />discharges. The applicant is in compliance. <br />Ground Water Recharge Capacity <br />The proposed operation will not significantly affect the recharge capacity of <br />the ground water. Most recharge areas are not in the mine plan area, or dis- <br />turbances which might affect recharge only cover small areas within the mine <br />plan area. The refuse pile does cover a large area, but is not in a signifi- <br />cant recharge area. Any aquifer which might be affected is of minor use and of <br />poor quality. The applicant is in compliance. <br />7 <br />
