• 3.0 Surface Water Information <br />The data collected from Oxbow Mining, LLC (OMLLC) surface water monitoring sites along <br />with the results of laboratory analyses are presented in Exhibit 1-Surface Water Information. <br />The following site discussions are presented from west to east through the OMLLC property. <br />H-1 -Lower Hubbard Creek <br />Surface water monitoring point H-i is located on Hubbard Creek, where this perennial stream <br />flows through the western edge of the OMLLC permit area associated with the abandoned but <br />reclaimed Somerset Mine facility area. The most recent surface activity in the area was the <br />reclamation of the lower Hubbard Creek site in 1996. The H-1 site is utilized as a down gradient <br />site to detect potential changes in stream qualify or quantity as a result of mining activities. <br />Hubbard Creek point H-1 was monitored in accordance with the permit requirements. Due to <br />the severe drought conditions, Hubbard Creek continues to exhibit much reduced flow volumes. <br />Other than reduced flow, no significant difference in the 2003 monitoring results from baseline <br />or historical measurements was noted. <br />B-1 -Lower Bear Creek <br />• Surface water monitoring point B-i -Lower Bear 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. Due to the prevailing drought conditions, during 2003 there was, again, only minimal <br />flow at B-1. <br />Retreat mining of D seam in the 1 sc West Panel under the Bear Creek drainage did not occur until <br />the 2"d quarter of 2003. The status of the Bear Creek road is assessed as part of ongoing <br />subsidence monitoring. No adverse effects as a result of mining activities were observed to have <br />occurred to the Bear creek road. <br />From a historical perspective it is important to remember that the Bear Creek drainage was also <br />undermined by extensive historic mine workings in the B and C seam of the Somerset mine. <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 ofrunoffin the drainage. Due to the prevailing <br />drought conditions, during 2003 there was, again, minimal stream flow at E-1. An analysis of <br />the limited data 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 />6 <br />
