Environmental Protection Plan, Schwartzwalder Mine 6-1 <br />• 6. DESIGNATED CHEMICALS MATERIALS HANDLING <br />This section of the EPP is not applicable to the Schwartzwalder Mine facilty, because no designated <br />chemicals are currently in use or being stored at the mine site. The Rules require that this section of the <br />EPP fully describe the procedures for the disposal, decommissioning, detoxification or stabilization for all <br />designated chemicals and toxic or acid-forming materials. The EPP must describe measures to be taken to <br />prevent any unauthorized release of pollutants to the environment and must include adequate reclamation <br />and closure practices for such designated chemicals, toxic or acid-forming materials and describe how <br />unauthorized discharge of acid mine drainage will be prevented. <br />Native rock at the Schwartzwalder Mine is not acid-generating. Instead, it is classified as having a low <br />potential to generate acidic drainage, and no acidic drainage has occurred from the mine or waste rock <br />facilities to date. Geochemical characterization of the waste rock piles is described in Section 7(b). The <br />water quality of the flooded mine workings is described in Section 9(b)(iv). The pH of groundwater in the <br />flooded mine is near neutral, and has been stable (no obvious increasing or decreasing trend) since <br />monitoring of mine water began in 2000. <br />• <br />• <br />4109C.090807 Whetstone Associates
