• Spring 2 is possible re-emergence of water in a small ephemeral drainage channel. <br />Flows, if any, are recorded in the spring and summer. The field pazameters are similaz to surface <br />water. Springs 3, 4, 5, & 6 are also possible re-emergence of surface water in a small ephemeral <br />drainage, with similar characteristics of flow diminishing from spring to summer, moderate pH, <br />low conductivity, and variation in temperature. <br />Of all the Springs 1-6, only Springs 4 and 5 usually have consistent flow. Springs 2 and <br />6, located in the ephemeral drainage channels below Springs 4 and 5, aze dry following spring <br />run-off. Although the actual locations of the six springs have not been surveyed, and only Spring <br />1 may be within the permit azea, all six springs are within the Hawksnest Creek drainage area. <br />Spring 7 is in the hill-side, cut-bank of the Coal Gulch trail. While the historical data for <br />Spring 7 indicates it is typically dry, monitoring indicates ground flow in the spring months, <br />resulting in high conductivity measurements. <br />Spring 8, the flow from the abandoned Oliver Mine, had recorded flow during all of the <br />monitoring events. The monitoring data collected is indicative of a ground water source. <br />Spring 9 is a spring or seep at the base of the landslide feature in the Unnamed Gulch. <br />Flow has been nearly continual, but at very low rates. High conductivity measurements indicate <br />ground flow. Spring 10 is a spring or seep at the base of the colluvium just above Old Highway <br />133 at the west end of the Hawk's Nest east site. Data for Spring 10 is similar to Spring 9, but <br />shows greater variability. <br />Spring 11 was covered during the reclamation of the Hawk's Nest East Mine by the <br />Division. It was originally in [he facilities azea below Old Highway 133. No flow was recorded <br />for Spring ] 1 in 1992 and 1993. In May of 1994, water began to collect in the road cut above <br />• Old Highway 133. This was monitored and an elevated conductivity and temperature was <br />measured. Flow was recorded in June and July of 1994, but the conductivity and temperature <br />measurements decreased. <br />Water damage to the pavement of Old Highway 133 had occurred next to the re- <br />emergence of Spring 11, and between the July and August monitoring events of 1994, the <br />Colorado Department of Transportation performed maintenance of the roadway and ditch in the <br />area of Springs 10 & 11. Both Springs 10 and 11 were dry at the time of the August monitoring, <br />with re-emergence of Spring 10 by October and Spring 11 by December of 1994. <br />During 1996, Springs 8, 10, and 11 continued to deposit material onto the road surface of <br />the old highway. The Colorado Department of Transportation continues to remove material from <br />the roadway and ditches in these azeas, leading to considerable variability in the monitoring <br />measurements. Roadway maintenance impacts to Springs 8, 10, and 11 by the Colorado <br />Department of Transportation aze beyond the control of Oxbow Carbon & Minerals, Inc. <br />Precipitation or snowmelt water infiltrates and percolates downward until the water <br />encounters a coarse zone or aquiclude which causes the water to surface area spring. The <br />primary use of the springs is by wildlife. The only spring to consistently contribute to surface <br />flow into the North Fork of the Gunnison is Spring 8. All other spring surface flow, if any, <br />returns to the ground before reaching the North Fork of the Gunnison. <br />Surface water monitoring stations AG-1 ("A" Gulch), BG-1 ("B" Gulch), CG-1 ("C" <br />Gulch), HN-1 (Hawksnest Creek), HG-1 (Hoopla Gulch), and BC-1 (Bazdine Canyon), are <br />designed to monitor flow characteristics in the respective creeks and gulches. These surface <br />water monitoring points aze designed to verify that the underground mine does not have an <br />• adverse effect on the quality or quantity of run-off from these ephemeral drainages that seldom <br />7 <br />
