MR23-323 2.04-9.2 08/07/23 <br />documented prehistoric sites resulted in a change in designation from “field eligible” to not eligible. A historic road <br />was identified in the records, but no evidence of the road remains. Survey results are presented in the Confidential <br />Appendix, in Exhibits 6P and 6S, Western Mining District (PR09-08, PR12-09) Cultural Resource Information, dated <br />February 2009 and May and August 2012. <br /> <br />18-Left Ventilation Shaft Installation and 16-Right Stabilization Boreholes (TR09-66 and MR11-253) - TC <br />contracted with Metcalf Archaeological Consultants, Inc. to complete an intensive Class III cultural resources survey <br />of the proposed 18-Left Ventilation Shaft Installation, in conjunction with the work previously discussed. A separate <br />survey addressed planned disturbance for the 16-Right Mine Stabilization Boreholes. The surveys covered lands <br />located in Sections 22 and 23, T5N, R87W. No previously recorded sites, isolated finds, or buried cultural materials <br />were found within the surveyed area. Survey results are presented in the Confidential Appendix, in Exhibit 6S. <br /> <br />Sage Creek/Twentymile Overland Conveyor (MR11-254) – TC contracted with Metcalf Archaeological Consultants <br />to complete an intensive Class III cultural resources survey of a corridor for a proposed overland conveyor, linking the <br />Sage Creek Mine with the Twentymile Coal Handling Facilities. The survey covered portions of Section 13, T5N, <br />R87W, and Sections 18, 19, 20, 21, 28, 29, and 32, T5N, R86W, and incorporated a number of areas that had been <br />previously surveyed. The survey resulted in recordation of one historic road segment, five previously recorded sites <br />were revisited, and three isolated finds were documented. The historic road segment is recommended as “non-eligible”, <br />due to historic alteration. One previously recorded site was reevaluated, and the portion within the surveyed corridor is <br />recommended as “non-contributing”. Construction limits or testing are recommended for a second previously recorded <br />site. Survey results are presented in the Confidential Appendix, in Exhibit 6T, Overland Conveyor (MR11-254) <br />Cultural Resource Information, dated June 2011. <br /> <br />15-Left Rock-Dust Installation, 16-Left Utility Borehole, and 5MN Borehole and Pipelines (TR11-77, TR11- <br />78, MR14-283, MR15-288) - TC contracted with Metcalf Archaeological Consultants, Inc. to complete intensive <br />Class III cultural resources surveys of the proposed 15LT Ventilation Installation, 16LT Utility Borehole and 5MN <br />Borehole and pipelines. The surveys covered lands located in Section 17, T5N, R86W, and Sections 23, 24, 25, 26 <br />and 27, T5N, R87W.

The surveys covered the planned drill-pads located in Sections 26, 27, 34, and 35, T5N, R87W. Some <br />of the sites had been covered by previous cultural resource surveys. No previously recorded sites, isolated finds, or <br />buried cultural materials were found within the surveyed areas. Survey results are presented in the Confidential <br />Appendix, in Exhibit 6L. <br /> <br />2012 WMD Exploration Program (MR12-261) - TC contracted with Metcalf Archaeological Consultants, Inc. to <br />complete intensive Class III cultural resources surveys of the 5 potential exploration drillholes to be completed in the <br />WMD. The surveys covered the planned drill-pads located in Section 36, T5N, R87W. No previously recorded sites, <br />isolated finds, or buried cultural materials were found within the surveyed areas. Survey results are presented in the <br />Confidential Appendix, in Exhibit 6L. <br /> <br />EMD Water Monitoring Wells (MR13-267) - TC contracted with Metcalf Archaeological Consultants, Inc. to <br />complete intensive Class III cultural resources surveys of 2 water monitoring well sites and the associated drill-pads <br />and to be completed in the EMD.
