RESPONSE: The maximum lift height for baekfilling the East Cresson Wildhorse <br /> Extension Mine will be 300 feet. <br /> 29. On page 12-11 of Volume I,the Applicant discusses that the storm water drainage flow-line in <br /> Grassy Valley will be directed through the backfilled area and will be clay-lined to prevent <br /> infiltration into the backfill. Please provided information regarding erosion control(for <br /> example: rip-rap, rock check dams, drop structures, etc.)of this drainage flow-line area. <br /> RESPONSE: The drainage flow line going across the eastern backfilled area of the <br /> East Cresson Wildhorse Extension Mine will be clan-lined, contain check dams, and rip- <br /> rap in areas as required. <br /> 30. On pages 12-12 and 12-13,the Applicant discusses the reclamation of the Arequa Gulch VLF <br /> and Squaw Gulch VLF. The Applicant states that the punctured liner will allow the conveyance <br /> of post-reclamation precipitation through the material on the VLFs and into the underlying <br /> diatreme. Please clarify if precipitation which falls on the reclaimed VLFs will solely infiltrate <br /> into the diatreme via the closure drains or will the underdrains convey storm water to the <br /> underdrain ponds. <br /> RESPONSE: The final reclamation plans for the AGVLF and the SGVLF were <br /> previously approved under Amendments 9 and 10, respectively and the reclamation <br /> plans for the VLFs did not change with Amendment ]]. Upon achieving the CNWAD <br /> removal criteria, the VLF liner systems will be breached in the same manner as <br /> previously approved. The liner will be perforated to prevent excessive accumulation of <br /> storm water infiltration in the neutralized ore behind the toe berms and to move meteoric <br /> drain down storm water into the underlying diatreme. It is anticipated that a drill rig <br /> will be used to drill from the surface of the ore on the VLFs through the synthetic and <br /> clay liners into the closure drains and underdrains, where appropriate. Holes will be <br /> drilled to puncture the liner above these features installed at several locations beneath <br /> the PSSAs. Drill holes puncturing the liners will allow meteoric water to drain into the <br /> closure drains and thus convey that water to the diatreme. <br /> 31. On page 12-14 of Volume I,the Applicant discusses the reclamation of haul roads. The <br /> Applicant states that as appropriate on a site-specific basis, culverts may be removed or <br /> retained, with proper drainage accommodation in the field. Please clarify that culverts on <br /> reclaimed haul roads will be removed. <br /> RESPONSE:Newmont would like to maintain the option of retaining culverts if it is <br /> environmentally prudent to do so. <br /> 32. On page 12-14 of Volume I, the Applicant states that soil typically is part of the fill materials <br /> that are pulled onto the road surface to assist with the reclamation effort. Please specify that this <br /> soil is used for the grading of haul roads and topsoil will still be replaced on the haul roads for <br /> reclamation. <br /> RESPONSE: As stated on Page 12-1, growth medium will be used to cover affected <br /> areas, including reclaimed haul roads. <br /> 33. On page 12-14 of Volume I, the Applicant states that CC&V may propose to retain and use <br /> certain road corridors and facilities. Please note that CC&V must request a revision to the <br /> approved Reclamation Plan to allow certain road corridors and some facilities to remain in place <br /> after reclamation is completed.This request will need to be submitted for Division review <br /> through the Technical Revision JR)process and approved by the Division. <br /> Page 11 of 14 <br />
