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 pressurefailed 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. 1. 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 permitand 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 theHoverman well drilled 192(?) feet deep (See Table 4-4). The rock strata slated <br />for disturbance dipssoutheast at an average dip of 27(See Map 4-2). Within the area of <br />the nearest adjudicated water well, the uppermost strata which will be disturbed in the <br />planned pit will be 1,000 feet below the bottom of the Hoverman well. Itshould be noted <br />that there are no water wells drilled deeper than 400 feet in this area (See Table 4-4). <br />Most wells in this area are shallow wells drilled in canyon bottoms, which contain limited <br />thicknesses of colluvium, alluvium and slope wash. All water wells in this area are <br />domestic producing 15 gpm or less than 15 gpm. Oakridge is the surface owner of the <br />permit and adjacent areas and as such has water rights for groundwater 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 drillingis 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 wasreported in the 1995 Annual Hydrology Reportand subsequent <br />submittals,providedto CDRMS. <br />2.04.7(2) Surface Water Information <br />The watershed of Carbon Junction Canyon discharges to the Animas River which drains <br />the San Juan River Basin. The USGS has flow records on the Animas River dating to <br />1895. The nearest gage station is located approximately 3.8 miles upstream of the <br />confluence of Carbon Junction Canyon with the Animas River (Map 4-4, Regional <br />Hydrology Map).
