Zach Trujillo <br />NECC: Attached are amended pages 2.05 -54 and 55. Pages 2.05 -54 explains that any water <br />bearing zone(s) in the shaft will be ring grouted from the surface. There should be no <br />concerns with using a shotcrete lining since water inflows will be sealed off by grouting, <br />DRMS: It is the Division's understanding from a meeting held between representatives of <br />New Elk Coal Company and the Division on April 17, 2012, that the proposed airshaft is to <br />be completely lined with concrete. Please send the necessary amended pages having the <br />proposed airshaft completely lined with concrete. <br />NECC: Concrete lining is not necessary to achieve long term control of water inflows. The <br />attached letter report explains how the shaft will be constructed to cut off any groundwater <br />inflows. Page 2.05 -54 was amended to reference Exhibit 44, Bates Shaft Construction <br />Clarification. <br />5. Through 11. Items Resolved. <br />12. DRMS: As per Rule 4.11.3 and 2.05.3, plans to return coal mine waste to abandoned <br />workings must include submittals for the approval of both the Division and the Mine Safety <br />and Health Administration. Please provide MSHA with all information required for their <br />approval. <br />NECC: MSHA will be provided all information necessary for their approval to return coal <br />mine waste abandoned working. <br />DRMS: The Division is willing to approve TR -64 with the stipulation that construction of the <br />proposed airshaft could not begin until the Division receives notice of MSHA's approval of <br />NECC's plan to return coal waste to abandoned working. <br />NECC: The DRMS' proposed stipulation is acceptable. <br />13.
