Tipple complex. The culvert was <br />first discussed in an CMLRD Inspection report dated October 11, 1988. <br />In 1987, belting was placed in the channel to reduce the downcutting <br />associated with the channel. The belting was only moderately successful so <br />riprapping was discussed with the field inspector as a replacement. After <br />careful review, a decision was made to install a culvert to control drainage <br />instead of riprap. This was discussed with David Berry during the October <br />field inspection. He concurred and installation v:as planned during the <br />month of November. However, weather and delivery delays beyond our control <br />prevented installation. On November 23, 1988, a telephone conversation was <br />held between David berry (ChiLRD) and myself during which I relayed the <br />problems which have occurred and problems which may occur if the system were <br />installed in the winter. These were improper establishment of a good clay <br />base, ground freeze, and the potential washing of the culverts base during <br />the spring runoff. He agreed and stated that since conditions beyond our <br />control exists, he saw no problem in waiting until the spring to begin <br />proper installation and would notify you of his conclusions and <br />recommendations. <br />If you have any questions or concerns, please call me. <br />Sincerely, <br />Richard Hughes <br />Environmental Specialist <br />RMH:dg <br />• <br />29587 Routt Coumy Rutl X27 <br />Oek Greek.
