NEW ELF COAL <br />COMPANY <br />RECEIVED <br />May 20, 2014 <br />Division of Reclamation, Mine and Safety JUN 0 2 2014 <br />1313 Sherman Street, Room 215 <br />Denver, Colorado 80203 Division of Reclamation, <br />Mining & Safety <br />RE: New Elk Mine Permit C- 1981 -012 <br />Technical Revision Application No. 70 <br />Dear Mr. Simmons: <br />Enclosedd is the application for a technical revision to: 1) Add an alternative design <br />for the Refuse Disposal Area Haul Road to utilize the current road as a one way <br />Haul road and keep the design for the haul road that was submitted and approved <br />with the Technical Revision #66 as a long term haul road design, <br />2) Update Bates Portal Surface Belt Line alignment, 3) Update locations of Culverts <br />and Ditches, 4) Re- designation of the Explosives Storage as Explosives Storage <br />and /or Chemical Storage. 5) Construct a new addition to the RDA Belt System, and <br />6) Construct new culvert C -19 at four stop at the entrance of the mine site. Culvert <br />C -19 has been relocated from Prep Plant Ditch D -22 and Culvert C -17 has been <br />extended to show one culvert not two. <br />RDA Haul Road: This revision is to add an alternative design for the RDA Haul Road <br />that approved by Technical Revision TR66. The alternative design is for a one way <br />traffic traversing the haul road at any given time (see attached RDA Haul Road <br />Operating requirements). This allows for haul trucks to have access to the road for <br />travel in only one direction at a time, but allows for travel in both directions. The <br />proposed design utilizes the existing road widths and grades for access to the RDA; <br />except for a few areas that needed to be re- graded to comply with the Haul Road <br />Regulations (see attached Map 11 and RDA Plan and Profile Exhibit). <br />Bates Portal Surface Belt Line: Updated Map 13, to show the actual alignment of <br />the belt and removed the projected alignment of the belt. <br />Culverts and Ditches Update: Culvert C -17 and C -19 were combined into a single <br />Culvert C -17: C -19 will be reinstalled at a different location (reference subsequent <br />paragraph Culvert C -19 Installation). Ditch D -67 was updated to current flow line <br />location. <br />Designation of the Explosives Storage and \or Chemical Storage: This allots for <br />chemicals to be stored with in the berms of the Explosives Storage area and will <br />contain any spillage that may occur. The Chemical will not be stored in direct <br />contact with any explosive material and all chemicals will be non - explosive and <br />non - corrosive. <br />12250 State Hwy 12 PHONE (303) 300 -8877 Or (303) 300 -8879 <br />Weston, Colorado 81091 FAX ((719) 868 -0044 <br />
