" -la- <br />G <br />VI. Hydrologic Balance: Ground Water - Rules 2.04.5, 2.04.7, 2.05.6(3), <br />and 4.05. <br />Information provided by the applicant with respect to ground eater is the <br />permit area can be found in Sections 4.2.2 through 4.2.5 in Volume I of the <br />application. Based on an analysis of these data the following determinations <br />have been made by the Division. <br />Drilling in the area indicates the presence of a saturated zone within the <br />Cameo seam (see Figure 4.2-3, Volume II). This saturated zone occurs outside <br />of the permit area and will not be encountered by projected mine workings <br />during this permit term. <br />The zone of saturation is the Cameo seam is rE:charged at the point were the <br />Cameo seam subcrops below the Salt Creek alltrvium approximately two miles <br />upstream of the mine. Very little recharge of the coal seams and sandstones <br />occur along outcrops due to the very low precipitation rate (8.8 inches) <br />and due to the steep slopes which favor runoff' over infiltration. <br /> The applicant has no monitoring well completed in strata overlying or <br /> within the zone of the underground mine vorkirigs. This is because of <br /> the inaccessibility of the steep terrain to truck mounted drill rigs. <br /> Previous holes drilled in the area of the portals have been dry to a depth <br /> in excess of 200 feet below the Cameo seam and its associated roof and <br /> floor strata are not saturated in the area of the <br />not a recharge area for these strate. mine. The mine zone is <br /> The mine workings are situated within a geologic structure identif ied as <br /> a graben. This graben is bounded on both sides by faults. Mining of the <br /> coal is not possible beyond the faults because: of the displacement of the <br /> coal seams. "' <br />One set of entries has encountered the fault on the south side of the graben. <br />At the time the fault was encountered, water (`loved into the mine. The <br />fault was eventually dewatered and all of the eater produced was contained <br />within the mine workings. The amount of eater experienced did not interfere <br />with the mining operation. <br />The fault will be encountered by the mine at a future time and will probably <br />produce water again. There is also a slight chance that the predicted <br />ground water zone of saturation will be encountered during this permit tem. <br />In order to monitor the effect of the operation on ground water resources <br />and to assist in the prediction of hydrologic impacts of future pewit terms, <br />the following stipulation is required: <br />4.
