11.0 Water Quality Monitoring Plan <br />Water quality monitoring requirements at the Van 4 Mine currently include the <br />monitoring requirements set forth in the existing CDPS General Stormwater Permit. <br />This level of monitoring is considered adequate for the current phase of the project, <br />because groundwater has not been encountered in the underground mine. Therefore, <br />Denison proposes to continue monitoring as set forth in the existing CDPS general <br />stormwater permit. <br />Groundwater monitoring is not proposed at this time, because groundwater has not <br />been encountered to date in the underground workings. Denison will monitor <br />groundwater conditions within the underground mine if water is encountered, and <br />when safe access is achieved into the mine. If groundwater is encountered within <br />underground workings, Denison will notify the Division. <br />• <br />• <br />11-1 <br />7:184988-Denison Mines\Task Order 4 - EPP Sunday Mines Group-Van4\Van4\FINAL Repod\FINAL - Environmental Protection Plan Van4.doc
