RESPONSE TO DMG CONCERNS PAGE 3 <br /> 5. SGC agrees with this comment; it will make provisions for <br /> sampling through the 1" pipe, and will draw and analyze <br /> samples annually. <br /> 6. SGC intends to monitor Cement Creek to determine whether any <br /> mine water is escaping directly to the surface, which event <br /> would be revealed by the presence of bromide tracer. SGC will <br /> remedy such an occurrence in a manner appropriate to its size <br /> and location. SGC welcomes DMG's and WQCD's input into the <br /> process of determining the appropriate action to be taken <br /> should a bypass be detected. Further, SGC will monitor the <br /> creek and tributary seeps and springs to detect anomalous <br /> excessive flows that might be related to the buildup of the <br /> mine pool water level. However, SGC does not agree with the <br /> position of WQCD, stated in a letter dated October 1, 1993, <br /> that "any seeps, discharges from adits or springs where the <br /> water quality changes have occurred after plugging, [are] <br /> point source discharges [requiring a permit] . . . . " SGC <br /> understands that DMG will require it to report anomalous <br /> increases to the WQCD. <br /> 7. SGC agrees in principle with the provision of a bond in the <br /> amount needed to replace the bulkhead once. SGC is willing to <br /> accept as a condition of the permit that it submit a detailed <br /> cost estimate and deposit the bond prior to closing the valve <br /> on the American Tunnel plug, per DMG Proposed Commitment No. <br /> 3 (document dated October 18, 1993) . However, SGC suggests <br /> that the point at which the bond is to be released should be <br /> defined more precisely. SGC requests that the bond be released <br /> five years after the date when the rate of rise of the mine <br /> pool is determined to have levelled off, as defined in <br /> Paragraph 4 above. <br />
