permited under the emergency discharge permit, and re- directed TORT dewatering to the Area # 1 Pit. The Pit <br />overflow goes via DRMS site 7 to Pond D, which may in turn flow into Foidel Creek via CDPS Outfall 005A <br />(a.k.a. site 84). As indicated earlier, future treatment of l ORT mine water is under consideration. <br />Mine Inflow: No unusual occurrences of inflow were noted as a result of the Annual Mine Inflow study. <br />Inflows are within the projected flows presented in the permit. Water quality has not changed significantly and <br />appears to mirror the quality of the adjacent spoil water. It appears that the elevated EC and iron readings are <br />associated with the water that has pooled in the mine sump, which is in contact with the overlying Marine Shale. <br />This contact has provided the opportunity for additional salts and iron to be leached from this unit. The pumping <br />of the sump should see a decrease in the elevation of the pool over time, with an anticipated decrease in the EC <br />and concentration of iron in the effluent. <br />Subsidence: During 2011, no ponds or surface creeks were undermined or subsided. No subsidence ponding <br />overlying historical mined areas along Foidel Creek, or Middle Creek was evident in 2011. No ponding was <br />evident along Fish Creek in 2011, with the exception of a small permanently ponded area around alluvial well <br />AVF -15. No significant /adverse water quality impacts relating to subsidence were evident in 2011. <br />19 <br />
