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 2006 and pertinent water <br />quality parameters are found below. <br />• <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: / /nwis- colo.cr.usgs.gov) or by contacting <br />the Department of Water Resources, Colorado River Talk at 303 - 831 -7135. Results of <br />the monitoring follows: <br />Field Analysis 6/16/06 <br />Field Analysis 12/04/06 <br />U/S NFG <br />D/S NFG <br />U/S NFG <br />D/S NFG <br />pH — su <br />8.6 <br />8.4 <br />pH — su <br />8.4 <br />8.2 <br />Temp °C <br />17.0 <br />17.3 <br />Temp ° C <br />0.2 <br />0.1 <br />Cond umhos /cm <br />90 <br />110 <br />Cond umhos /cm <br />150 <br />180 <br />Diss Oxygen <br />Flow — cfs <br />563 <br />Flow — cfs <br />101 on 11/29/06 <br />Laboratory Analysis <br />Laboratory Analysis <br />Cond umhos /cm <br />136 <br />139.7 <br />Cond umhos /cm <br />148 <br />183 <br />TSS - mg /I <br />19 <br />11 <br />TSS - mg /I <br />3 <br />1 <br />TDS - mg /I <br />148 <br />155 <br />TDS - mg /I <br />127 <br />157 <br />Iron - mg /I <br />0.13 <br />0.09 <br />Iron - mg /I <br />0.02 <br />0.02 <br />Manganese mg /I <br /><0.010 <br /><0.010 <br />Manganese mg /I <br /><0.010 <br />0.02 <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 2006 reporting period. <br />-3- <br />
