Lab analysis for ammonia NH and NH <br />(2) Measure weekly for conductivity, PH, temperature, oil /grease, settleable solids, and flow for all <br />discharging water from Outfalls 007, 008 and 009. Test for total suspended solids, settleable <br />solids,and iron once a month for Outfalls 007, 008 and 009. <br />(1) <br />Full suite laboratory analysis (February, May, August, and November on quarterly schedule), if <br />pond(s) are discharging for Outfalls 007 008 and 009. <br />(4) Measure water conductivity, PH, temperature, oil /grease, and flow /depth. Have full suite <br />laboratory analysis February and August for Semi - Annual schedule and August for Annual <br />schedule) for listed groundwater monitoring wells and surface monitoring stations. <br />(3) <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 <br />using 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 <br />sampling locations is five. Calamity Draw contains three stations while the remaining two <br />stations are located on the West Lateral Ditch. <br />Stations SW -N102 is located on a tributary of Calamity draw and will remain as a monitoring <br />point for water leaving Pond 007. This will also act as the NPDES 007 discharge monitoring <br />point for Pond 007. The two stations, SW -N108 and SW -N109 are also located on Calamity <br />Draw. The upstream station, SW -N108 is located just west of Lincoln Street as it flows from <br />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 />REVISED JULY 2006 2.04.7 - 46 <br />
