Fan Facility, Culvert Addition. and Balch Weigh Washdown <br />Dear Mc Gorhmn, <br />Twentymile Coal Company is requesting a minor revisions to permit C-82-056 as per the Field Decision Fomt - <br />Minor Revision of March 29, 1996. The modifications focus on [he followin,: <br />• pouring concrete as approved in TR-24 for the fan facility and associated structures, <br />• placing an 18-inch culvert on TCC shop access road immediately south of wash bay. <br />• placing a 48-inch culvert in ditch D-3 below existing 48-inch culvert, <br />• placing an I S-inch culvert on the road to the explosives magazines east of existing 18-inch CMP, and <br />• installing support poles and a pipeline [o route batch weigh washwater to Pond C. <br />The concrete pouring ar the fan facility does not require any changes to the permit or bond calculations. No changes <br />were made from the approved design in TR-24. Map 24 and Exhibit S, Table B have been revised to indicate the <br />locations of the new culverts. The I S-inch culvert a[ the Pond A road was previously approved under Permit C-81- <br />071, but was not installed or shown on Map 24. This culvert was also included on Map 24 and bond calculations <br />provided for removal. 'flte washdown for [he ba[clt weigh facility was originally slated to go to a sump in TR-20. <br />Due to space limitations, a drain line from the batch weigh facility ro Pond C supported by poles has been proposed. <br />Changes [o the text with regard to this drain line are provided in pages 2.05-16(aq and 2.05-I6(a2). <br />An estimate of bond for these projects is included in this revision and totals $2,100. TCC currently maintains <br />sufficient surplus of bond to cover this amount. <br />If you have any questions or require further information, phase contact me at (970) 870-2750. <br />TN'ENTYMILE COAL COMPANY, <br /> <br />Tavis D.
