2.0 APPROVED HYDROLOGICAL MONITORING PROGRAM <br />Table 1 summarizes various approved monitoring sites and monitoring requirements for New Horizon <br />1 and New Horizon 2 mines. They are shown on Plate 1. <br />2.1 Surface Water Monltoring -New Horizon 1 Mine <br />The total number of surface water monitoring locations at New Horizon 1 is twelve (12) including six <br />(6) NPDES discharge monitoring points (Outfall 001 through Outiall 008), three (3) spoil springs and <br />three stations on Tuttle Draw; SW-N1, SW-N3 and SW-N4. The monitoring schedule and <br />parameters being monitored are shown in Table 1. <br />J 2.2 Surface Water Monltoring -New Norizon 2 Mlne <br />The total number of surface water sampling locations is five (5). Calamity Draw contains three (3), <br />SW-N102, SW-N108 and SW-N109 stations while the remaining two stations are located on the <br />West Lateral Ditch, SW-N104 and SW-N105. <br />] Stations SW-N102 is located on a tributary of Calamity draw and will remain as a monitoring point <br />for water leaving Pand 007 (Outfall 00~. This also acts as the NPDES 007 discharge monitoring <br />point for Pond 007. The two other stations, SW-N708 and SW-N109 are located on Calamity Draw. <br />The upstream station, SW-N108 is located just west of Lincoln Street as it flows from under the <br />road. This station will define water quality and quantity before it enters the area potentially <br />I influenced by the mine. SW-N109 is located on Calamity Draw wesl of the mine permit boundary <br />r but east of the Nucla waste water lagoons. This station will define the water quality and quantity as <br />it leaves the site but before it is influenced by the waste water lagoons. <br />Stations SW-N104 and SW-N105 are located on the West Lateral Ditch. These two stations <br />1 monitor flow and water quality of the ditch system as it enters the upstream area of the mine and <br />1 as it leaves the mine area. <br />Monthly flow, pH, temperature, and conductivity measurements are taken at the surface monitoring <br />locations to assess potential impacts of the mine and to fulfill the requirements for the water <br />augmentation plan. Water quality parameters listed in Table 2 are collected on a quarterly basis. <br />8y continuing with this parameter list, the baseline can be utilized to better define the conditions as <br />the mining proceeds. <br />2 <br />
