Recovery analyses were attempted on the water bearing zones at Wells 17B and 82 -5. <br />The data for Well 17B is illustrated on Table 4 -3 and Figure 4 -2 in Exhibit H. The <br />results yielded a transmissivity value for the monitored zone of 0.01 gpd/ft. The zone is <br />considered too small for consideration of recharge and storage characteristics and for <br />beneficial use. <br />The recovery analysis for drill hole 82 -5 was also attempted, but the standard procedure <br />of bailing the water from the hole with air pressure failed to lower the original static. <br />water level at 90.9 feet below the surface. At 316 feet (TD) water production was <br />measured at 50 gpm (± 5 gpm). The expected inflow to the pit from this water bearing <br />zone has been projected to approximate the following flow rates. Boundaries are <br />assumed to occur at the drainage divide 5,200 feet northeast of the north pit boundary, <br />and the Animas River 5,500 feet southwest of the south pit boundary. The recharge area <br />is the permeable strata overlying the Carbonera and Shamrock coal seams and their <br />outcrops. As the coal is mined, most of the water will drain into the pit and become part <br />of the pit discharge pumped into Sediment Pond No. I. Water retained in the coal and <br />removed with the coal during the mine operation will presumably become a small portion <br />of the water utilized for coal crushing. The water zone intercepted in Hole 82 -4 has been <br />estimated to yield up to 150 gpm of water, utilizing the drill rig air pressure system. <br />Oakridge has obtained a well permit and associated conditional water rights for beneficial <br />use of this water. The boundaries are assumed to be the same as those set forth above. <br />The recharge area is likely restricted to the outcrop and subcrops of this zone. <br />Use of these waters by the mine operations should not cause damage to existing surface <br />water and well rights. The Animas River is not over - appropriated. The nearest water <br />well is to Hoverman well drilled 192( ?) feet deep (See Table 4 -4, Exhibit H). The rock <br />strata slated for disturbance dips southeast at an average dip of 27° (See Map 4 -2). <br />Within the area of the nearest adjudicated water well, the uppermost strata which will be <br />disturbed in the planned pit will be 1,000 feet below the bottom of the Hoverman well. It <br />should be noted that there are no water wells drilled deeper than 400 feet in this area (See <br />Table 4-4). Most wells in this area are shallow wells drilled in canyon bottoms, which <br />contain limited thicknesses of colluvium, alluvium and slope wash. All water wells in <br />this area are domestic producing 15 gpm or less than 15 gpm. Oakridge is the surface <br />owner of the permit and adjacent areas and as such has water rights for groundwater <br />resources. <br />As can be seen from the above, one to three water bearing zones exist above the coal <br />seams to be mined. The zones are perched water existing in fractured strata and are not <br />considered to be located in aquifers. Characterizations above adequately describe the <br />nature and occurrence of the water. No further drilling is necessary to characterize the <br />water associated with the perched water in the existing holes. <br />Groundwater monitoring data has been collected since the initial permitting of the mine. <br />All data collected has been initially reported in the 1995 Annual Hydrology Report, <br />submitted to CDMG. <br />• <br />Abridged Permit Document 4 -12 Feb 2008 <br />
