~iiiiiiiuiiniuiii Doc Date:12/11/2001 1993 ANNUAL RECLAMATION REPORT FOIDEL CREEK MINE PERMIT C-82-056 This report addresses the surface disturbances associated with the underground mining operations conducted by Twentymile Coal Company. TCC mines federal and private coal in Routt County, Colorado utilizing a retreating longwall system. As such, surface disturbances have been limited to surface support facilites consisting of small acreages. Currently, TCC is responsible for the disturbances consisting of the Fish Creek Borehole, Sandstones Substation, Fish Creek Tipple, Rockdust Tank, and Surface Facilities as denoted on the Annual Reclamation Map. The surface facilities are located in and on old spoils produced by the CYCC Mine 1 operation during the 1970's, with the portals driven into the old low wall remnant. In addition, the newer tipple facilities, haulroads, rail spur, explosive bunkers, and coal stockpile in the area of Pinnacle Peak have been transferred to TCC. Given that the current disturbance is limited to those areas necessary for operation of the mine, TCC does not anticipate any large scale reclamation to be undertaken in the near future. At such time as reclamation commences, TCC will follow the approved reclamation plan found in Permit C-82-056 using the approved seed mixtures. • Those parcels already reclaimed within the shaded areas by CYCC will remain the responsibility of CYCC. Parcels which are subsequently affected by TCC operations within such reclaimed areas will become the responsibility of TCC. Specifically, the proposed coal refuse pile disposal area (denoted in Area 2 on the ARR Map) is the responsibility of TCC. It is planned to commence construction of the coal refuse pile during 1994. Likewise, those portions of the reclamation which has been re-disturbed or newly disturbed in the area of Pond F has become the responsibility of TCC as previously discussed. For a more complete discussion of the surface areas involved, refer to Permit C-82-056. 1993 Reclamation ---------------- During 1993, no reclamation other than the wastewater treatment facility borrow area, the exploration drill pads, and the additional waterline repair activity in the area of Pond F was conducted. These areas were stabilized, re-topsoiled and re-seeded in accordance with the approved plan. In addition, limited supplemental seeding was conducted on a few TCC topsoil stockpiles to ensure proper cover as a normal husbandry • practice.
