under the road. This station will define water quality and quantity before it enters the area <br />• potentially influenced by the mine. SW-N109 is located on Calamity Draw west of the mine <br />permit boundary but east of the Nucla waste water lagoons. This station will define the water <br />quality and quantity as it leaves the site but before it is influenced by the waste water lagoons. <br />Station SW-N101 was dropped from the monitoring program in the Calamity draw as Stations <br />SW-108 and SW-109 replaced its functions. <br />Surface station SW-N104 monitors the flow and water quality of the West Lateral Ditch as it <br />enters the area upstream of the mine permit. To more accurately reflect the water quality <br />immediately upstream of the mine, the sample site has been moved from its original location <br />within the Town of Nucla to the HDPE inlet structure located at the mine property boundary. <br />Monitoring of the CCC West Lateral Ditch downstream of the mine property at site SW-N105 <br />has been discontinued since the installation of the HDPE pipelines mentioned above in West <br />Lateral Irrigation Ditch - Flow and Water Quality section eliminates the possibility any mine <br />water interacting with ditch water. Map 2.04.7-1A shows the new location of SW-N104. <br />Monthly flow, pH, temperature, and conductivity measurements will be taken at the all <br />monitoring locations that have a recordable flow to assess potential impacts of the mine and to <br />fulfill the requirements for the water augmentation plan. Water quality parameters listed in <br />Table 2.04.7-2 will be collected as follows; quarterly basis for all discharging NPDES Outfalls <br />(SW-102), semi-annual basis for stations SW-N104, SW-N108 and SW-N109, and annual <br />basis for SW-N1 and SW-N3. All NPDES mine discharge points are sampled monthly by both <br />NPDES and Table 2.04.7-2 requirements. <br />•
