will divert stream flow from the mainstem of Cement Creek (including the North Fork of <br /> Cement Creek) to the current water treatment system for treatment. Upon valve closure at the <br /> Terry Tunnel and at the property line in the American Tunnel, SGC will adjust the American <br /> Tunnel treatment facility as necessary to accommodate the remaining flow from the lower <br /> American Tunnel and the diverted flow from Cement Creek. This stream diversion will be <br /> regulated in volume from essentially all stream flow in low-flow months up to the equivalent <br /> stream flow lost to the treatment system due to mine sealing during high flow. This diversion <br /> will be monitored and controlled to manage impacts at the Reference Point. Following <br /> completion of all mitigation projects on the A list, SGC may reduce or eliminate the treatment <br /> of Cement Creek at the American Tunnel treatment plant. SGC will notify the Division ten <br /> business days prior to substantially reducing the quantity of flows being treated relative to the <br /> treatment plant capacity. In its notice to the Division, SGC will provide its analysis that water <br /> quality will be maintained at the reference point (A72) with the decreased treatment of Cement <br /> Creek flows, and the amount that it intends to reduce these flows. The water treatment facility <br /> will remain in operational condition until a Successful Permit Termination Assessment <br /> pursuant to paragraph 14. Upon permit termination, the facility will be dismantled and the <br /> treatment ponds and surface disturbances reclaimed in accordance with SGC's DMG permit. <br /> VI. MONITORING <br /> 10. Monitoring Requirements As long as the Consent Decree is in effect, or unless <br /> otherwise agreed in writing between the parties, SGC will monitor the following sites <br /> 38911-3 5...96 15 <br />
