(3) Full suite laboratory analysis (February, May, August, and November on quarterly schedule), if there <br />is a measurable discharging for all NPDES Outfalls <br />(4) Measure water conductivity, PH, temperature, oil/grease, and flow /depth. Have full suite laboratory <br />' analysis (February and August for Semi - Annual schedule) for listed surface monitoring stations. <br />(5) Measure monthly water depth for groundwater monitoring wells (GW's). <br />(6) Measure water conductivity, PH, temperature, and depth. Have full suite laboratory analysis using <br />the Ground Water Parameters on following list (February, May, August, and November) <br />Surface Water Monitoring_ New Horizon 2 Mine The total number of surface water sampling <br />locations is five. Calamity Draw contains two stations, Tuttle Draw has two stations and West <br />Lateral has one station. <br />' Stations SW -N102 is located on a tributary of Calamity draw and will remain as a monitoring point <br />for water leaving Pond 007. This will also act as the NPDES 007 discharge monitoring point for <br />' Pond 007. The two stations, SW -N103 and SW -N108 are also located on Calamity Draw. The <br />upstream station, SW -N108 is located just west of Lincoln Street as it flows from under the road. <br />This station will define water quality and quantity before it enters the area potentially influenced by <br />t the mine. SW -N103 is located on Calamity Draw west of the mine permit boundary and near <br />County Rd CC. This station will define all the water quality of Calamity Draw that is down gradient <br />of the active mine. Station SW -N101 was dropped from the monitoring program in the Calamity <br />draw as Station SWA 08 replaced its function. <br />' Surface station SW -N 104 monitors the flow and water quality of the West Lateral Ditch as it enters <br />the area upstream of the mine permit. To more accurately reflect the water quality immediately <br />upstream of the mine, the sample site has been moved from its original location within the Town <br />of Nucla to the 26" HDPE inlet structure located at the mine property boundary. Monitoring of the <br />1 CCC West Lateral Ditch downstream of the mine property at site SW -N105 has been discontinued <br />since the installation of the HDPE pipelines mentioned above in West Lateral Irrigation Ditch - <br />' Flow and Water Quality section eliminates the possibility any mine water interacting with ditch <br />water. Map 2.04.7 -1A shows the new location of SW -N104. <br />Flow quantities, pH, temperature, and conductivity measurements will be taken at all monitoring <br />locations that have a recordable flow to assess potential impacts of the mine and to fulfill the <br />t requirements for the water augmentation plan. Water quality parameters listed in Table 2.04.7 -2 <br />will be collected as follows; quarterly basis for all discharging NPDES Outfalls (SW-102), semi- <br />annual basis for stations SW -N103, SW -N104, SW-N108, SW-N1 and SW-N3.
