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 aze presented in Exhibit I-Surface Water Information. <br />The following site discussions aze presented from west to east through the OMLLC property. <br />H-1 -Lower Hubbazd 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 facility azea and Blue Ribbon Mine Facility. Until 1996, the most <br />recent surface activity in the azea was the reclamation of the lower Hubbazd Creek site. In 2005 <br />the Hubbard Fansite was permitted and constructed. The H-1 site is utilized as a down gradient <br />site to detect potential changes in stream quality or quantity as a result of mining activities. <br />Mining activities include both the OMLLC Hubbazd Creek facilities and the Blue Ribbon Mine <br />facility, <br />Hubbard Creek point H-1 was monitored in accordance with the permit requirements. Hubbard <br />Creek is a stream that also serves as atrans-basin diversion from the Terror Creek reservoir <br />during the summer irrigation season. The Hubbard Creek drainage is also used extensively by <br />USFS and BLM recreationists and Bowie Resources mining related activities. Hubbazd Creek <br />continues to exhibit summer flow volumes in response to the management of upstream <br />diversions. No significant difference in the 2006 monitoring results from baseline or historical <br />measurements was noted. <br />B-1, B-2 and B-3 -Beaz Creek <br />The Beaz Creek canyon light use road is used extensively to access the upper reaches of Beaz <br />Creek for cattle and sheep grazing, logging, mine exploration and methane ventilation activities, <br />hunting, etc. <br />BB=1 -- Surface water monitoring point B-1 -Lower Bear Creek, an ephemeral drainage, is <br />monitored to verify that the Elk Creek mine does not have an adverse affect on the quality of <br />runoff in the drainage. During 2006 there was, again, only minimal to no flow at B-1 after the <br />conclusion of spring snowmelt. <br />No additional retreat mining of D seam occurred under the Bear Creek drainage during 2006. <br />The status of the Bear Creek road is assessed as part of ongoing subsidence monitoring, No <br />adverse effects as a result of mining activities were observed to have occurred to the Bear Creek <br />road in 2006. <br />From a historical perspective it is important to remember that the Beaz Creek drainage was also <br />undermined by extensive historic mine workings in the B and C seam of the Somerset Mine. <br />• B-2 and B-3 -- In accordance with the Elk Creek Federal coal lease COC-61357 "Water <br />Replacement Ptan" stipulation, surface water monitoring points B-2 and B-3 are monitored for <br />flow twice annually after tributary flow from side channels between the two points has ceased. <br />
