b. Agreed upon voluntary cleanup activities will be <br />deemed complete, and SGC's obligations fulfilled, when <br />the agreed upon work is performed. WQCD will not revise <br />its requests foz work or demand additional work: after <br />monitoring the water quality effects of the agre~ad upon <br />work. <br />c. After completion of the agreed upon work, plugging and <br />sealing of the mine opening, performance by SGC of all <br />obligations under its Reclamation permit, cessation of <br />discharge of water from the American Tunnel or assumption <br />by another party of permit responsibility for such <br />discharge, and release of its Reclamation permit, SGC <br />will be released from its permit obligations under the <br />Colorado Water Quality Control Act and regulations, with <br />the exception of the following contingency: <br />i. Limited quantities of water may escape from the mine <br />through the Brenneman Vein after filling of the mine <br />pool. The mitigation proposed for this settlement is <br />intended to mitigate effects of this eventuality, should <br />it occur. In the event that significant quantities of <br />water escape directly from the mine via other, <br />unpredicted, identifiable discrete passageways following <br />• closure, SGC will assume cesponsibility for the control <br />of such water. Should such escape occur, SGC will <br />consult with WQCD and DMG and devise control strategies <br />to deal with the escaping water. Such strategies may <br />include performing additional mitigation, grouting of <br />fractures, treatment of the escaping water or drawdown <br />and treatment of the mine pool to control escape, if <br />necessary. As long as SGC is working in good faith to <br />control such escape, WQCD will exercise regulatory <br />discretion in SGC's favor to the extent that it .,an, and <br />refrain from citing or levying large fines agaanst the <br />company. <br />4. SGC assumes that the quality of any water migrating From the <br />mine via normal groundwater mechanisms following closure and <br />flooding will not be any worse than the quality of water <br />migrating through the mountain but not entering tt~e mine, <br />because hydrogeochemical processes within the flooded mine <br />workings and the mountain following flooding will return the <br />hydrological regime to a close approximation of its pre-mining <br />~- state. <br />5. Water flowing around the flooded workings following closure is <br />not part of SGC's regulatory responsibility. <br />• - 2 <br />
