The numerical designation <br />for each reply corresponds to your review. <br /> <br />1. Due to the lack of springs and/or seeps that could <br />be influenced by our operations, sampling of springs <br />and/or seeps were not required as a part of the <br />original permit. There is an extensive de-watering <br />system in existence via the Carlton and Roosevelt <br />Tunnels. This, combined with t the extensive <br />underground mining historically performed in this <br />area, has removed virtually all springs and/or <br />seeps. <br />2. Filtering will be used for all surface and ground <br />water samples. <br />3.. The water levels fluctuate while the pH and cyanide <br />values remain relatively constant (see Attachment <br />A). <br />4. See Attachment B. <br />5. Carlton Tunnel has been monitored for 15 to 20 years <br />by private owners. Surface and ground water data <br />goes back approximately five (5) years for some <br />sites and three (3) years for moat all sites. <br />
