• Bowie Resources, LLC April 26, 2005 <br />Bowie No. 2 Mine <br />2004 Annual Hydrology Report <br />Surface Water Monitoring Stations: STREAMS AND DITCHES <br />Thirty four surface water monitoring stations including the North Fork of the Gunnison, Tenor <br />Creek, Hubbazd Creek, Freeman Gulch, the Deer Trail Ditch, Stephens Draw, the Fire Mountain <br />Canal and Gulches A through D aze monitored quarterly for field pazazneters and semi-annually <br />for full suite analysis. The results of the 2004 field and laboratory studies aze consistent with <br />baseline information supplied in the permit application. <br />The USGS, with right of way permission from the USDA-Forest Service, has installed <br />continuous monitoring stations on both Hubbazd and Tenor Creeks. Similaz stations aze <br />installed neaz each creek's confluence with the North Fork of the Gucuuson River. These stations <br />have been calibrated by the USGS's hydrology department and now provide accurate readings for <br />the 2004 Annual Hydrology Report. <br />Surface Water Monitoring Stations: SMALL AREA EXEMPTIONS <br />The locations of the small azea exemptions aze presented on Map 20. The Applicant will monitor <br />the flow from the small azea exemptions to assure compliance with 4.05.2(3). The Applicant <br />will use its best efforts to obtain samples. The samples will be analyzed for pH, conductivity and <br />• total settleable solids. Samples will be in compliance if they contain settleable solid levels of 0.5 <br />ml/1 or less and the pH is greater than 6.5 and less than 9.0. No small azea exemption sampling <br />was performed during 2004. <br />Coal Member of Mesaverde <br />Seventeen drill holes were monitored during the 2004 sampling season. These holes were <br />monitored quarterly for Geld parameters and semi-annually for full suite laboratory analysis. <br />Data collected and evaluated is consistent with the baseline information provided in the permit <br />application. The mine construction work during 1997 required the elimination of four monitored <br />drill holes. These holes aze DH 42, DH 52, DH 54 and DH 55 and were located neaz the mine <br />portals. Drill Holes DH-13 and DH-34b were eliminated by mining. Drill hole DH-34c was <br />damaged by ground movement. DH-16 is blocked at 60-feet so no monitoring can be performed. <br />Drill Holes DH-57, 57a and DH-58, 58a were added in conjunction with the Tenor Creek Coal <br />Exploration Plan, with monitoring beginning in the fall of 1999. Drill holes DH-57 and DH57a <br />were destroyed by longwall mining during 2001. Drill holes DH-65, DH-66, DH-67D, <br />DH-67b1w and DH-67abv were added in conjunction with the Ironpoint Federal coal lease, with <br />some monitoring beginning during the fall of 2000. DH-67D was damaged during the yeaz <br />(2003) so no monitoring was performed. The DH-67 holes were refurbished during 2004. DH- <br />58 and 58a were eliminated by mining during late 2003 so they will no longer be monitored. <br />DH-66 was eliminated by mining during eazly 2004 so it will no longer be monitored. <br />Drill holes DD-NM4X98-27, 29 and 29 aze in-mine monitoring holes which were added to the <br />• monitoring program during 2003. The three monitoring points were abandoned when the mine <br />4 <br />
