2015 AHR Page 2 <br />During 2009, the rail spur lying south of 1.9 Road was reclaimed, graded and seeded. A phase <br />III bond release (SL -5) was approved on the reclaimed conveyor corridor lying south of 1.9 <br />Road, and a permit revision (PR -4) was approved to change the land use at the Unit Train <br />Loadout from Fish and Wildlife to Industrial/Commercial. Halliburton Energy Services <br />purchased the UTL and began construction of their commercial sand plant operations. <br />During 2010 coal fines from the UTL were hauled to CRDA-1 and reclamation of CRDA-1 road <br />was finalized in September. Ponds 1 and 2, sewage lagoons, topsoil pile 4 along with other <br />areas of the UTL were reclaimed, regraded and reseeded. A phase III bond release (SL -6) was <br />approved for the Commercial/Industrial portion of the South Portal. <br />During 2011 Pond 7, sumps and ditches at the North Decline and Pond 8 at the South Portal <br />were reclaimed, regraded and reseeded. A phase III bond release (SL -7) was approved for the <br />UTL, Railroad Loop, the remainder of the conveyor corridor and the permanent flood control <br />dike. <br />During 2012 Ponds 6, 10, 11 and 13, CBA#1 Sump and miscellaneous sedimentation control <br />features at the North Portal and along Coal Creek were reclaimed, regraded and reseeded. A <br />permit revision (PR -5) was approved allowing Coal Creek and Coal Gulch to remain in their <br />present alignment and allows for the North Portal upper diversion ditch and a portion of Topsoil <br />Pile 2 to remain as permanent features. <br />During 2013 Pond 9 was reclaimed, regraded and reseeded. <br />No reclamation was performed in 2014. <br />No reclamation was performed in 2015. <br />The general format of this report is the same as in previous years. <br />Surface Water <br />Water flow and quality on the Colorado River is monitored by the U.S. Geologic Survey (USGS) <br />at various locations. The closest location is Station No. 09095500, which is located upstream <br />approximately 7 miles north east of the mine site. Water quality and flow from this site are used <br />as a general representation of the Colorado River up gradient of the mining operation. There is <br />a diversion to the Government Highline Canal, the addition of Plateau Creek and the addition of <br />other minor drainages between the monitoring site and the mine site. Data Pages SQ -91 <br />through SQ -94 includes information supplied by USGS on this site during the 2015 Water Year. <br />The total flow at this site for the Year was 3,059,000 acre-feet which is 110% of the normal <br />average flow for the period 1934 - 2015 (2,780,000). The estimated TDS load for the Year was <br />1.30 million tons. This estimate is made by converting values for conductivity reported on page <br />SQ -92 to TDS per acre feet and multiplying by the monthly flow in acre feet. The low flow for <br />the Year was recorded as 1310 CFS on January 2, 2015. The river was carrying approximately <br />0.75 tons of TDS per acre-foot on November 26, 2014, the closest data point. This flow and <br />
