Subsequent establishment of permanent vegetation in reconstructed drainages insures future channel <br />. stability. <br />• <br /> <br />This combination of appropriate conservation measures coupled with an effective drainage repair <br />program insures successful establishment of reconstructed drainage channels at Trapper Mine. <br />1.3 Drainage Control Documentation <br />All drainage control structures at Trapper Mine have been built according to the approved permit plan <br />and 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. <br />Appendix Q also provides other drainage control documentation, including Professional Engineer dam <br />construction 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 <br />of surface water monitoring data that shows that Trapper is consistently in compliance with all NPDES <br />effluent discharge requirements. <br />2
