Sediment Pond <br />The sediment pond has been monitored since its construction in November 2008 in <br />' accordance with DRMS stipulations. Although storm events and significant snow melt <br />events have occurred, none have resulted in stormwater discharge from the pond. As a <br />result, no stormwater samples have been collected from the pond to date. Energy Fuels <br />will continue to monitor the sediment pond for discharge and will collect samples in the <br />event of discharge. <br />Dolores River <br />The Dolores River is required to be monitored for selenium upstream and downstream <br />from the confluence of Lumsden Creek in accordance with BLM stipulations to the mine <br />permit when the following conditions are met: <br />1) The Whirlwind Mine treatment plant is discharging treated water, <br />2) There is continuous flow from the middle tributary of Lumsden Creek to the <br />Dolores River, and <br />3) Selenium levels have been in exceedance of the CDPS permit effluent limits in <br />the past two years. <br />Because water treatment of mine water has been suspended, it was unnecessary to <br />monitor Lumsden Creek for discharge to the Dolores River in the First Quarter 2011 to <br />determine if samples were required. Energy Fuels will commence monitoring the <br />Dolores River for discharge from Lumsden Creek and take samples, as necessary, at such <br />time that treatment and discharge of mine water resumes. <br />Hydrological Monitoring Summary <br />Refer to Table 7 for the hydrological compliance monitoring summary and status for <br />Whirlwind Mine. <br />3
