III. COMMENTS -COMPLIANCE Below are comments on the inspection. The comments include discussion of observations made during the inspection. Comments also describe any enforcement actions taken during the inspection and the facts or evidence supporting the enforcement action. This was a partial inspection conducted by Kent Gorham of the Colorado Division of Minerals and Geology. Weather on this day was warm and mild. Signs and Markers The mine identification sign will be updated following a determination as to the future status of the mine operation. Hydrologic Balance Bedrock ground water monitoring wells were inspected. The following observations were noted. Well Water Level (feet) Conductivity (umhos/cm) Comments MW- 6I 163. 9 2100 Bubbles in water - gas well within 150 feet MW- 6U 167. 0 NA Measured from to of PVC casing MW- 6C 164 .8 NA Measured from to of PVC casing MW- 5I 123 .8 600 Well not marked or labeled MW- 5C 123. 45 NA Well clearly marked MW- 5U 129. 7 NA Sound of running water coming from well MW- 3I 281. 0 3900 Only a small amount of water in well MW- 1 NA NA Test well, ca ed and marked MW-10 NA NA Well ca ed, marked. and unlocked MW- 1C NA NA Well ca ed. marked, and unlocked MW- 4C 142. 55 1700 Bubbles in water - ca ed, marked MW- 4I 135. 4 2100 Bubbles again - ca ed and marked MW- 4U 153 .2 2400 Bubbles again - ca ed and marked Bubbles in the water taken from the wells could possibly be methane. In the instances where bubbles were observed, gas wells were located in close proximity to the well cluster. At site MW-5 cluster. Alamosa Canton was flowing and the electrical conductivity measured in the stream was identical to the value measured in well MW-5I. There may be some connection between the stream flow and the ground water in the well. MW-5U continues to produce an audible sound of water cascading or running inside the well casing. Possibly a fault to the near surface is allowing surface water to infiltrate the shallow sub-surface. 3
