Bowie Resources, LLC <br />Bowie No. 2 Mine <br />2013 Annual Hydrology Report Revised May 11, 2015 <br />parameters and semi - annually for full suite analysis. The results of the 2013 field and <br />laboratory studies are consistent with baseline information supplied in the permit <br />application. <br />The USGS, with right of way permission from the USDA - Forest Service, installed <br />continuous monitoring stations on both Hubbard and Terror Creeks. Similar stations are <br />installed near each creek's confluence with the North Fork of the Gunnison River. <br />These stations have been calibrated by the USGS's hydrology department and now <br />provide accurate readings for the Annual Hydrology Reports. <br />Surface Water Monitoring Stations: SMALL AREA EXEMPTIONS <br />The locations of the small area exemptions are presented on Map 20. The Applicant <br />will monitor the flow from the small area exemptions to assure compliance with <br />4.05.2(3). The Applicant will use its best efforts to obtain samples. The samples will be <br />analyzed for pH, conductivity and total settleable solids. Samples will be in compliance <br />if they contain settleable solid levels of 0.5 ml /I or less and the pH is greater than 6.5 <br />and less than 9.0. No small area exemption sampling was performed during the year. <br />Coal Member of Mesaverde <br />Sixteen bedrock wells were monitored during the 2013 sampling season. These holes <br />were monitored quarterly for field parameters and semi - annually for full suite laboratory <br />analysis. Data collected and evaluated is consistent with the baseline information <br />provided in the permit application. The mine construction work during 1997 required the <br />elimination of four monitored drill holes. These holes are DH 42, DH 52, DH 54 and DH <br />55 and were located near the mine portals. Drill Holes DH -13 and DH -34b were <br />eliminated by mining. Drill hole DH -34c was damaged by ground movement. DH -16 is <br />blocked at 60 -feet so no monitoring can be performed. Drill Holes DH -57, 57a and <br />DH -58, 58a were added in conjunction with the Terror Creek Coal Exploration Plan, with <br />monitoring beginning in the fall of 1999. Drill holes DH -57 and DH57a were destroyed <br />by longwall mining during 2001. DH -58 and 58a were eliminated by mining during late <br />2003 so they will no longer be monitored. Drill holes DH -65, DH -66, DH -67D, DH -67blw <br />and DH -67abv were added in conjunction with the Iron Point Federal coal lease, with <br />some monitoring beginning during the fall of 2000. DH -67D was damaged during 2003 <br />so no monitoring was performed. The DH -67 holes were refurbished during 2004. DH- <br />66 was eliminated by mining during early 2004 so it is no longer monitored. <br />DH -67blw has a pinched casing so no samples were obtained. The technician put <br />some extra effort to obtain a sample during the year but was unable to get his bailer <br />down to the water. <br />Drill holes DD- NM4X98 -27, 28 and 29 were in -mine monitoring holes which were added <br />[.1 <br />
