Minor revision 59-37 was approved in the field in order to <br />allow CYCC to temporarily reroute the bar ditch which ran along the south <br />side of haul road C then into Pond E. The ditch will be rerouted across the <br />road (low water crossing), along the base of the slope which is west of the <br />shop area, then into ditch E-1 (see Figure MR 89-37). The rerouting of the <br />ditch is in response to the construction of the Twentymile Coal Company's <br />(TCC's) new tipple facility. Once the tipple pad construction is complete <br />the ditch will be routed back around the TCC tipple pad into Pond E. <br />To complete this project, CYCC has also shown the proposed permanent <br />location of Ditch D-5 (TCC Technical Revision 89-08, C-82-056) which will <br />route water around the south side of the TCC tipple facility to Pond E and <br />render the temporary ditch obsolete. <br />Attached is Figure MR 89-37, "Temporary Diversion Ditch & Proposed <br />Ditch D-5" showing the location of the ditches. <br />If there are any questions, please feel free to call me. <br />Sincerely, <br />Rich d~Hughe <br />Environmental Specialist <br />Enclosures <br />RH/dg <br />c~RUs <br />
