Rule 4.05.13(4)(c) Annual Hydrology Report Requirements <br />(i) Water quantity monitoring data for the water year is presented Appendix 1 and Appendix 2 <br />of this report. <br />(ii) Water quality monitoring data for the water year is presented in Appendix 1 and Appendix 2 <br />of this report. Discharge monitoring reports (DMR) are submitted to the Colorado Department <br />of Public Health and Environment. Copies of each DMR are provided quarterly to the Division <br />during the report year and are included in this report by reference only. <br />(iii) A written interpretation of the data has been requested by the Division in accordance with <br />Rule 4.05.13(4)(c)(iii) and is included within this annual hydrology report. <br />The monitoring timeframe for this annual hydrology report is from October 2016 through <br />September 2017. <br />A description of the surface and ground water monitoring plan including the monitoring <br />frequency is located in Section 2.04.7. All monitoring locations are shown on Map 2.04-7-1A <br />and summarized on Table 2.04.7-1. This previously mentioned information can be located in <br />Permit No. C-1981-008. <br />Surface Water <br />Surface water monitoring sites are comprise of several sites which comprise the current, <br />upstream and downstream condition and are briefly described below. Please see Map 2.04.7-1A <br />for locations. <br />• SW -N102 is located on a tributary of Calamity Draw at the discharge point for Pond 007. <br />• SW -N103 represents the downstream condition on Calamity Draw. <br />• SW -N108 represents the upstream condition upstream Calamity Draw. <br />• SW -N104 is located at the inlet of the 26" HDPE pipe on the West Lateral Ditch <br />upstream of the mine permit area. <br />• SW -NI is located on Tuttle Draw and represents the upstream condition above mining. <br />• SW -N3 is located on Tuttle Draw and represents the downstream condition below <br />mining. <br />Surface monitoring data for the water year for all sites listed above can be found in Appendix 1. <br />New Horizon currently samples each surface water site for a variety of quality parameters. Of all <br />the parameters that are analyzed for, several key indicator parameters have been identified and <br />are addressed annually for the hydrology report. These parameters are lab pH, lab conductivity, <br />TDS, sulfate, calcium, iron, magnesium, and sodium. Water monitoring data through 2016 can <br />2 1 P a g e <br />
