1 <br />' Homestzke Mining Company -Bulldog Mine-Lower Tailing Pond <br />' relate to the potential for discharge to surface waters. It is also agreed that the DMG would <br /> implement the ground water protection provisions of Rule 3.7.1 and would shaze information <br /> with the WQCD to assist in their effort to evaluate the potential for surface water quality impacts. <br />' January S, 1996 -the DMG and HMC meet to discuss the agency's concern for the potential <br /> ground water impacts associated with the two historic tailings disposal facilities. This concern is <br /> based on DMG's understanding of previous seepage problems at the Lower Tailing impoundment <br />' and [he results of DMG's tailings leachate testing performed on Bulldog tailings in the fall of <br /> 1995. <br />1 During the January 8, 1996 meeting the DMG agrees to act on tJre jollowing: <br /> <br />' 1. If the historic water quality data demonstrates fhat ground water, down-gradient <br />from the tailings impondments, is no more contaminated than up-gradient, or if <br /> contaminate concentrations do not exceed the States Water Quality Protection <br />' Standards, the DMG would find that reclamation has been achieved to protect <br />existing and future uses ofground water. <br /> <br />' 2. If water quality data shows static or improving trends, the DMG would ftnd that <br />reclamation has been achieved to protect existing and future uses of ground <br /> water. <br />I , 3. If the water quality data reflects that leachate from the tailings is potentially <br /> impacting ground water, then HMC may be required to continue the monitoring <br /> until the extent of contamination can be determined and mitigation measures <br />' implemented. <br /> To provide an understanding ajthe Bulldog Mine ground water issue and to support <br />' decision making, the DMG requests HMC provide the jollowing information: <br /> 1. The results of private well sampling conducted by HMC down-gradient <br /> from the Lower Tailings Impoundment in 1981 & 1982. <br />' 2. All data and an analysis ojthe data collected from monitoring well <br /> installed down-gradient from the Lower Tailings Impoundment. <br /> 3. A description and assessment of the effectiveness of the remedial measures <br />' implemented by HMC at the Lower Tailings Impondment. <br /> ~. information on any wells, stock ponds, etc. potentially affected by seepage <br /> from the tailings facilities. <br />' .i. Ambient ground water quality data both up-gradient and down-gradient <br /> of both the Upper and Lower Tailings Facilities. <br /> <br /> <br />
