SURFACE WATER MONITORING <br />' There are four (4) active surface monitoring points within Bear Coal's permitted <br />area. Pond 004, Outfall 001, Upstream North Fork (U/S NFG), Downstream North Fork <br />(D/S NFG). No monitoring is currently required at Springs G26A, G-2613, G-26C and <br />' CR- 12. Location of Pond 004 and NFG's can be found on map "Figure 11" located in <br />Appendix A. <br />The French Drains were not monitored during the year because they were <br />removed during the 1997 reclamation project. <br />The results of groundwater data collected during 2007 and pertinent water quality <br />parameters are found below. <br />North Fork of the Gunnison River <br />The North Fork of the Gunnison River (USGS Station 09132500) is to be <br />monitored during June and December for field parameters and laboratory analysis for <br />conductivity, total dissolved solids, total suspended solids, iron and Manganese. Actual <br />stream flows are obtained from the web (http:// waterdata.usgs.gov/nwis) or by <br />contacting the Department of Water Resources, Colorado River Talk at 303-831-7135. <br />Results of the monitoring follows: <br />Field Analysis 6/16/08 Field Analysis 12/07/08 <br /> U/S NFG D/S NFG U/S NFG D/S NFG <br />pH - su 8.1 8.1 pH - su 7.3 7.8 <br />Temp °C 11.3 11.5 Temp °C 1.4 1.6 <br />Cond umhos/cm 50 60 Cond umhos/cm 140 160 <br />Flow - cfs 2450 Flow - cfs 55 <br />Laboratory Analysis Laboratory Analysis <br />Cond umhos/cm 85.1 96.1 Cond umhos/cm 168.9 204.6 <br />TSS - mg/I 32 40 TSS - mg/I 9 15 <br />TDS - mg/I 74 81 TDS - mg/I 131 144 <br />Iron - mg/I 0.32 0.39 Iron - mg/I 0.37 0.41 <br />Manganese mg/I 0.004 0.013 Manganese mg/I 0.003 0.004 <br />Iron and Manganese are both analyzed for total recoverable. In reviewing field as well <br />' as laboratory analysis, the Bear No. 3 Mine had no significant deleterious effect on the <br />North Fork of the Gunnison River during the 2008 reporting period. <br />1 <br />-3-
