• 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-1 is located on Hubbazd Creek, where this perennial stream <br />flows through the western edge of the OMLLC permit azea associated with the abandoned but <br />reclaimed Somerset Mine. The most recent surface activity in the azea was the reclamation of <br />the lower Hubbard Creek site in 1996. The H-1 site is utilized as a down gradient site to detect <br />potential changes in stream quality or quantity as a result of mining activities. <br />Hubbazd Creek point H-1 was monitored in accordance with the permit requirements. Due to <br />the severe drought conditions, Hubbazd Creek exhibited much reduced flow volumes. Other than <br />reduced flow, no significant difference in the 2002 monitoring results from baseline or historical <br />measurements was noted. <br />B-1 -Lower Bear Creek <br />• Surface water monitoring point B-1 -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 drought conditions, during 2002 there was no flow at B-1. <br />Retreat mining of D seam in the 15~ West Panel under the Bear Creek drainage will not occur <br />until the 2na quarter of 2003. <br />The Bear Creek drainage was also undermined by extensive historic workings in the B and C <br />seam in 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 of runoff in the drainage. Due to the drought <br />conditions, during 2002 there was no flow at E-1. <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 upgradient site to monitor Elk Creek prior to <br />• entering the OMLLC surface facility. Due to the drought conditions, during 2002 there was no <br />flow at E-1. <br />
