• B-2 corresponds to a mid-Bear creek location roughly corresponding to the south limit of the Elk <br />Creek Federal Coal lease. B-3 corresponds to an upper Beaz Creek location roughly <br />corresponding to the north limit of the Elk Creek Federal Coal Lease. Generally, due to the <br />ephemeral nature of Bear Creek and the propensity for flows to quickly cease by late June, flow <br />measurements are most often obtained in mid-June. <br />BEAR CREEK FLOW INFORMATION <br /> <br />Date Site B-2 Site B-3 <br />June 10, 2003 0.25 cfs 0.21 cfs <br />June 16, 2003 0.097 cfs 0.088 cfs <br />June 15, 2004 0.02 cfs 0.041 cfs <br />June 22, 2004 0.0 cfs 0.0174 cfs <br />June 15, 2005 1.036 cfs 1.085 cfs <br />June 30, 2005 0.39 cfs 0.13 cfs <br />June 7, 2006 0.047 cfs 0.033 cfs <br />June 13, 2006 Trace flow Trace flow <br />The information is collected in order to aid in analyzing 1) potential water depletions and 2) <br />potential for injury to any Beaz Creek water rights. The sampled Beaz Creek flows were very <br />. minimal and typically variable. Analysis of the data, as well as subsidence monitoring and <br />observations in the field, suggests no anomalies nor any indication of adverse effects related to <br />mining activities. <br />E-1-Lower Elk Creek <br />Surface water monitoring point E-1 -Lower Elk Creek, an ephemeral drainage, is monitored as a <br />down gradient site to verify that the Elk Creek mine and the surface facility located at Somerset <br />does not have an adverse affect on the quality of runoff in the drainage. During 2006 there was, <br />again, minimal stream flow at E-1 after spring snowmelt. An analysis of the limited data <br />suggests there is no adverse impact of the Elk Creek mine to Lower Elk Creek. <br />E-2-Upper Elk Creek <br />Surface water monitoring point E-2 -Upper Elk creek, an ephemeral drainage, is monitored to <br />verify that the Elk Creek mine does not have an adverse affect on the quality of runoff in the <br />drainage. In addition, the site will serve as an up-gradient site to monitor Elk Creek prior to <br />entering the OMLLC surface facility. During 2006 there was, again, minimal flow at E-2 after <br />spring snowmelt. An analysis of the limited data suggests there is no adverse impact of the Elk <br />Creek mine to Lower Elk Creek. <br />S-1 -Upper Sanborn Creek and S-2 -Lower Sanborn Creek <br />Surface water monitoring points S-1 -Upper Sanborn Creek and S-2 -Lower Sanborn Creek <br />were established to monitor the flow in ephemeral Sanborn Creek above and below the disturbed <br />area of the Sanborn Creek Mine site. Sanborn Creek also received discharge water from the <br />
