Simmons Colorado Division of Reclamation, Mining and Safety Office of Mined Land Reclamation 1313 Sherman Street, Room 215 Denver, Colorado 80203 Re: Mountain Coal Company, LLC, West Elk Mine; Permit No. C-1980-007; Technical Revision No. TR-147 for Future B Seam Short-term MVBs Pads and Roads Dear Mr. Simmons: Mountain Coal Company, LLC (MCC) submits the attached application form, proposed public notice, and a B Seam MVBs pads and roads location map in application of Technical Revision No. TR-147 for prospective short-term mine ventilation boreholes (MVBs) pads and roads to be constructed above future B seam longwall panels LWB26 through LWB29 that will be mined beneath already mined and sealed longwall panels LWE1 through LWE5. The layout of the proposed temporary MVBs pads and associated roads is shown on the attached map. The pad for each of the four longwall panel's start-lines (the eastem-most pad) that will contain two MVBs will be about one (1) acre in size. All other pads will be about a half(1/2) acre. As is shown on the map, about ten (10.0) miles of new temporary roads will need to be constructed to access these pads. Also, about one (1) mile of existing trail will be widened to a 14' travel width (with the same 25' construction width as for new roads) and then reclaimed back to a trail width (about 5' wide) when no longer needed for access to MVBs. Several roads that were used to access past E seam MVBs were left in place and will also be utilized to access the B seam MVBs and reclaimed thereafter. A few reclaimed E seam MVB numbers are noted on the map where those MVB pads were located to provide a reference for the new B seam pad locations. Four (4) reclaimed E seam MVB pads will be crossed by new road construction. These areas are also shown on the attached map. As has been a successful practice for several years at West Elk Mine, in the fall or spring before planned MVB pad construction, the planned sites and roads approved with this revision will be jointly field-reviewed by U.S. Forest Service and MCC personnel and the locations adjusted if need be. A revision application will be submitted at that time if site and/or road adjustments are needed to minimize resource impacts.
