COLORADO LEGACY LAND <br /> M-1977-300 APPLICATION AMENDMENT#5,COMMENT AND RESPONSE SUMMARY TABLE JAMMEN <br /> COMMENT NO. COMMENT PO SE T. <br /> 3) A discussion of vertical gradients in the vicinity of the <br /> Black Forest Mine is presented in Section 8 of the <br /> Schwartzwalder Environmental Protection Plan <br /> (Whetstone Associates,2016). This document is <br /> Attachment B of Technical Revision#23. <br /> 4) Please see previous response to DRMS's comment on <br /> Exhibit G. Static water levels from the initial <br /> Construction Materials 110 Permit(M-2001-036)and <br /> current static water levels are discussed in Exhibit G. <br /> Additionally,the depth to water for groundwater wells <br /> (as completed) is summarized in Table 8-4 of the <br /> Schwartzwalder Environmental Protection Plan <br /> (Whetstone Associates,2016). This document is <br /> Attachment B of Technical Revision#23. Current depth <br /> to water for groundwater wells are provided in quarterly <br /> reports to DRMS. <br /> A discussion of fracture interactions with Ralston Creek <br /> is presented in Section 8 of the Schwartzwalder <br /> Environmental Protection Plan (Whetstone Associates, <br /> 2016). This document is Attachment B of Technical <br /> Revision#23. A connection between the mine pool and <br /> Ralston Creek via the Schwartz Trend was investigated in <br /> 2008-2009. Water quality monitoring and gamma <br /> surveys indicated no evidence of chemical loading from <br /> the mine pool via the Schwartz Trend and that the mine <br /> pool was not contributing loading to Ralston Creek. <br /> 5) The maximum mine pool elevation of the <br /> Schwartzwalder Mine pool is 150-feet below the Steve- <br /> level adit. This level was agreed to by DRMS and Cotter <br /> because it is sufficient to establish a hydraulic gradient <br /> away Ralston Creek. The elevation of the Steve Adit <br /> (6,602 ft amsl)is approximately the same as the <br /> elevation of the Black Forest 6,604 ft amsl . The Black <br /> PAGE 11 OF 12 <br />
