Introduction <br />The information assembled in this 2015 Annual Hydrology Report (AHR) <br />includes data collected from all water monitoring sites at Hayden Gulch <br />Terminal, LLC (HGT) Hayden Gulch Loadout (CDRMS Permit C-92-081) for the <br />year 2015. Locations of water monitoring sites can be found in Figure 1 <br />(Appendix A). <br />In 2011, the tipple was scrapped. Topsoiling and reseeding of the tipple <br />and coal storage areas were also completed in 2011. The office area and <br />the rail line were left in place. Until 2013 when the offices were <br />reclaimed. <br />The Tie -Across Haul Road (formerly associated with the Seneca II -W Mine, <br />CDRMS Permit C-82-057) was transferred to the Hayden Gulch Terminal on <br />January 4, 2012. <br />Meteorological Data <br />Data from the National Climatic Data Center's (NCDC) Hayden Station are <br />used to evaluate the precipitation trend. These data are provided in <br />Appendix Al. For this year, 19.77 inches of precipitation was measured, <br />which is 1.56 inches (90) above the 1981-2014 average, 18.21 inches. All <br />months except October, January, February, March, April, June and <br />September were above average. Snowpack runoff, as estimated by totaling <br />November through March precipitation values, was 6.81 inches, which was <br />0.51 inches (7°s) less than the 1981-2014 average, 7.32 inches. <br />Water Sampling and Measurement Techniques <br />Field conductivity and pH meters were calibrated prior to each day of <br />use. The conductivity meter is calibrated using a potassium chloride <br />solution with an electrical conductivity in the 1,000 to 4,000 umhos/cm <br />range. The pH meter is calibrated using NBS traceable buffers with pH <br />values of 7 and 10. Water level measurements are taken with a water <br />level indicator or directly from a steel tape. <br />
