Tabetha Lynch, DRMS <br />Page 2 <br />July 1, 2015 <br />• Please verify the ownership, uses, and location information for all existing wells or other <br />developed groundwater resources are up to date as required by Rule 2.04.7 (1)(a)(iv). <br />Rule: 2.05.4(2)(g) — Reclamation plan <br />Rule 2.05.4(2)(g) refers to sealing or managing the mine openings, exploration holes, wells, and other <br />openings. <br />The 001 discharge valve was closed upon activation of Outfall 016. The Outfall 001 pipe was then <br />permanently plugged with pumped concrete in conjunction with the South Portal facilities area <br />reclamation project. The plugged Outfall 001 pipe that extended out of the sealed South Portal began <br />to leak at some point following the sealing of the pipe with 6 cubic yards of grout SCC submitted <br />Technical Revision No. 56 in March 2008 to provide a plan to completely reseal the pipe. TR 56 was <br />approved by the Division and the pipe has been sealed in accordance with the approved plan. SCC <br />capped off the end of the pipe and encased it in approximately two additional cubic yards of concrete. <br />Rule: 2.05.6(3) — Protections of Hydrologic Balance <br />Rule: 2.05.6(3) was reviewed for protection of the hydrological balance in reference to groundwater <br />and alluvium. Information adequately meets the rule and can be found in Tab 17. Alluvial valley floor <br />migrations are covered in Tab 21. One permanent discharge point exists (Outfall 016), which drains <br />from the South Mine workings. Probable Hydrologic Consequences are adequately discussed in Tab 19. <br />All information required is presented, no additional comments are required. <br />Rule: 2.06.2 —Experimental Practices Mining <br />No experimental practices were conducted. <br />Rule: 4.04(6) — Support Facilities <br />All information required is presented, no additional comments are required. <br />Rule: 4.05.10 — Mine Entry and Access Discharges <br />Requirements are adequately covered as discussed under 2.05.4(2)(g) above for the South Portal. <br />Discharge from the North Mine workings ceased in 1999 when mining ceased and the pumps were shut <br />down. The mine was subsequently sealed and backfilled and future discharge is not anticipated based <br />on projected final ground water elevation. <br />Rule: 4.05.11(1)-(2) — Groundwater Protection <br />Adequately covered in the Hydrology Description in Tab 7, and Protection of the Hydrological Balance in <br />Tab 17. Refuse pile contamination has been adequately addressed in Tab 19. <br />
