Per comments in the pending SL -14 Phase 1 Bond Release (May 2013), major drainages within the SL -15 <br />bond release block have been removed and placed within exclusionary corridors until full stabilization can <br />be achieved. Constructed drainages will still be constructed and maintained until full stabilization can be <br />achieved in each re- constructed drainage. <br />1.3 Drainage Control Documentation <br />All drainage control structures at Trapper Mine have been built according to the approved permit plan and <br />are functioning as designed. Approved sedimentation pond designs, including hydrologic modeling <br />backup, are routinely provided to DRMS and are located in Appendix Q of the permit document. Appendix <br />Q also provides other drainage control documentation, including Professional Engineer dam construction <br />certifications and diversion ditch designs. <br />In addition to design information, documentation that Trapper Mine drainage control structures are <br />functioning in accordance with the approved permit plan is provided by continuous surface water <br />monitoring. The "Annual Hydrologic Report" section of Trapper's annual reports contains a vast amount of <br />surface water monitoring data that shows that Trapper is consistently in compliance with all NPDES <br />effluent discharge requirements. <br />2 <br />
