barriers between the SWMD and the Western Mining District, and the EMD and the Northern Mining District, <br />respectively. These barriers currently retain accumulated water from mine inflows and contain submersible <br />pumps at the low points for mine dewatering. These pumps will be used to recycle water back to the surface for <br />washplant make -up water or underground for dust suppression, or the water will be discharged directly to Foidel <br />Creek. TC's existing discharge permit was modified to allow discharge directly to Fish Creek. Water from the <br />SWMD and EMD is pumped to the surface at the Fish Creek Borehole and 10 -Right Borehole locations, <br />respectively. <br />The water recycling/discharging system required minor changes to the existing water distribution system. Water <br />pumped from the mine exits the mine at Site 109. From this point, the water is piped to the Area 1 Pit where it <br />is retained to allow for settling of sediments and aeration. A pump station has been installed towards the south <br />end of the pit. Installation involved burying forty-foot beams under the road and extending them over the pit. A <br />platform was constructed on the beams extending over the pit. A submersible pump, along with hosing and <br />piping, is suspended from the platform into the pit. A winch installed on the platform assists in setting the pump <br />at the desired elevation. A second pump was added to provide make -up water for Washplant II. Control <br />equipment for this second pump was installed at the existing pump platform location <br />The water pumped from the Area 1 Pit can go in one of four directions, or a combination of them: 1) Pit to <br />Washplant I; 2) Pit to Washplant II; 3) Pit to mine water recycling line; and/or 4) Discharge to Foidel Creek. <br />The water pumped from the pit is piped to a de- sander, located at an old well site. From this point it is piped to <br />one or both of the washplants or piped over and tied into the existing mine water line. A line has been installed <br />from the de- sander back to the pit so that the back -flush water can be returned to the pit. The location of the <br />lines is shown on Map 24. The trenches were dug with a backhoe or trackhoe. During the excavation process <br />suitable plant growth media was removed and windrowed adjacent to the trench and then replaced on top of the <br />sub -soils returned to the trench. <br />TR12 -81 2.05 -97.8 06/22/13 <br />
