OF MINERALS <br />& GEOLOGY <br />Re: Colowyo Coal Co. L.P., (C-81-019) <br />Request for Technical Revision No. 46 <br />Modification to the Mine Plan and Topsoil Handling Plans. <br />Dear Mr. Walker: <br />Attached please find a request for Technical Revision No. 46 to the Colowyo Coal Co. L.P., <br />Permit C-81-019. TR-46 provides for a modification to the Mine Plan and Topsoil Handling <br />Plans. We are principally making changes to Drawing No. 23 -Mine Plan and Drawing No. 28 - <br />Topsoil Handling described as follows. <br />Area 1-East end of the East Pit. -- After having reviewed the results of recent resource <br />confirmation drilling, geologic modeling and burn delineation we have determined that the mining <br />limits in the east end of the East pit can be extended further to the east. As such, we have made <br />minor modifications to the respective lines on the Mine Plan Drawing No. 23 and the Topsoil <br />Handling Drawing No. 28. <br />Area 2 -East end of the West Pit --Similarly, we have reviewed the approved mining limits for <br />the east end of the West Pit in the vicinity of the pit parking lot (SE1/4SE1/4 of Section 4) and we <br />have determined that modifications are necessary to facilite the connection of the West Pit <br />boxcut development into the East Pit. The Proposed change is included on Drawing No. 23. <br />Area 3 -North Limit of the Section 16 Pit. -- The current north coal removal line for the shovel <br />cuts (1998 -2002 area) was incorrectly located on the earlier maps. Topsoil and overburden has <br />been removed and an additional 225' x 2000' area of coal removed from the area formerly <br />known as the 2008-2010 mining area (see the 1/20/97 Drawing No. 23). To correct this <br />mapping error the Drawing Nos. 23 and 28 have been modified to more accurately show the <br />areas in question. To further reduce the possibility of confusion, especially in areas where the <br />West Pit re-mines a portion of the Section 16 Pit, the modified drawings also add the remaining <br />portion of the 2008-2010 mining area with the former 2003-2007 area to form the 2003-2010 <br />area. We hope the modified boundaries provide additional clarity to the mine plan boundaries. <br />
