<br /> 5/12 <br />6.4.4 Exhibit F- Reclamation Plan Map <br /> <br />20. Exhibit F General Requirements: Rule 6.2.1(2)(e) requires an appropriate scale on the <br />map(s) be provided. As the submittal was received in electronic format, a scale bar is <br />needed. Please include a scale bar on Exhibit F. <br /> <br />Response: Exhibit F includes a scale bar in the lower left-hand corner. <br /> <br />21. Drainage Concern: Please see Comment No. 19 above. If a change in the final grading <br />plan is necessary, please provide an updated Exhibit F to reflect the change(s). <br /> <br />Response: Exhibit F is revised to reflect potential locations of the infiltration galleries. <br /> <br />22. Canyon Walls: Exhibit F shows a “thin” wall to remain between the existing Red Creek <br />canyon and the excavated quarry. Please provide rationale for the width of the material to <br />be left in place. The DRMS is also concerned about the potential impact on the <br />geotechnical stability of the wall after reclamation (see Comment No. 35 below) <br /> <br />Response: Exhibit F now includes cross-section figures showing the distance between Red Creek <br />canyon wall and the excavated quarry. The distance between Red Creek canyon walls and the <br />excavated quarry is substantial. Based on the Blasting Plan (Appendix 4.1) pre pared by Holcim <br />with data from SRK Geotechnical Services, the distance is adequate to remain stable during <br />reclamation. In addition, the cross-sections do not reflect high wall sloping that will increase <br />geotechnical stability of the “thin” wall. <br /> <br />23. Bear Creek Quarry Diversion: During our July 19, 2023, inspection, we discussed the <br />“outfall” of the Bear Creek Diversion in the approved Exhibit F-1 from AM-1 (see image <br />capture below). Please address this as part of AM-2 or provide a written commitment to <br />address this change as part of the technical revision process by May 30, 2024. <br /> <br /> <br /> <br /> <br /> <br />Response: The BCQ Diversion will be addressed as a Technical Revision for AM-01 prior to May <br />30, 2024. <br /> <br />
