Ground Water Information provided by the applicant with respect to ground water in the permit area can be found in Sections 2.3.2, 2.6, and 4.4 in Volume I and Sections 2.3.9, 2.4.4, and 4.2 of Volume VI of the application. Based on an analysis of these data and information, the following determinations have been made by the Division: Drilling in the area indicates the presence of a saturated zone within the Cameo seam (Figure 4.4-I ). Data indicates that the Carbonera seam, which overlies the Cameo seam, also becomes progressively saturated to the northeast of the five-yeaz permit area. The zone of saturation in the Cameo seam is probably recharged at the point where the Cameo seam subcrops below the East Salt Creek alluvium, approximately three miles upstream of the mine. Very little recharge of water in coal seams and sandstones will occur along the outcrops due to the low annual precipitation rate (8.8 inches) and the steep slopes which favor runoff over infiltration. The applicant has no monitoring well completed in strata overlying the underground mine workings. This is because of the inaccessibility ofthe characteristically steep terrain of the "Book Cliffs" region to truck-mounted drill rigs. Previous explorations drill holes in the area of the McClane Canyon Mine have been dry to a depth in excess of 200 feet below the Cameo seam. The Cameo seam's associated roof and floor strata aze not saturated in the area of the mine. The mine is not a rechazge area for these strata (see Figtue 4.4-1 and Appendix G). The Munger Canyon Mine is located updip of the McClane Canyon Mine, which suggests that a similar situation will occur. The rock strata within the permit and mine plan areas dip uniformly to the northeast at 2 degrees. No faults have been identified in the permit and mine plan azeas of the Munger Canyon Mine, but two high angle faults form a graben structure into which the adjacent McClane Canyon Mine is developed. These faults may contribute to the equilibrium of ground water levels in the bedrock aquifers in the region. One set of entries in the McClane Canyon Mine encountered a fault on the south side of the graben structure in July of 1982. The fault produced water which reached a peak inflow rate of approximately 5.4 gpm during February of 1983. Since that time, the inflow rate has decreased to about 1.6 gpm recorded during the first quarter of 1985. Minor unmapped faults may be encountered by the mine at a future time and produce mine inflows. In order to monitor the effect of the operation on ground water resources and to assist in the prediction of hydrologic impacts of future permit terms, the following stipulation is required: 3?
