enhance soil moisture conditions. A detailed description of the <br />cultural practices employed in the reclamation process is presented <br />under Section 780 of Permit C-81-071 for Mines 1, 2, and Eckman <br />Park. <br />The cumulative number of disturbed acres still under CYCC liability <br />is approximately 3,100 with a total permitted area of approximately <br />7,150 acres. With the acreages associated with the transfer of <br />liabilities to TCC for the surface facilities, there are less than <br />5 acres left to reclaim under CYCC liability, these areas being <br />associated with" the dragline dismantling pads. There are three <br />large areas which have been released from bond, two of these being <br />located on Mine 2, the other being located at Mine 1. These areas <br />are heavily vegetated, and have been included for reference only. <br />- Twentymile Coal Company. <br />TCC mines federal and private coal in Routt County, Colorado <br />utilizing a retreating longwall system. As such, surface <br />disturbances have been limited to surface support facilites <br />consisting of small acreages. Currently, TCC is responsible for the <br />disturbances consisting of the Fish Creek Borehole, Sandstones <br />Substation, Fish Creek Tipple, Rockdust Tank, and Surface <br />Facilities. The surface facilities are located in and on old spoils <br />produced by the CYCC Mine 1 operation during the 1970's, with the <br />portals driven into the old low wall remnant. In addition, the <br />newer tipple facilities, haulroads, rail spur, explosive bunkers, <br />and coal stockpile in the area of Pinnacle Peak have been <br />transferred to TCC. Current disturbed area acreage within TCC <br />liability is approximately 340 acres, with a total permitted <br />acreage of approximately 14,600 acres. Given that the current <br />disturbance is limited to those areas necessary for operation of <br />the mine, TCC does not anticipate any large scale reclamation or <br />large additional disturbance to occur in the near future. <br />Page 2 <br />
