DE-T. OF NATURAL RESO::RCES <br />FOR SNOWMASS COAL COMPANY <br />The Snot,*mass Coal Cotupany is seeking a minor permit revision to the <br />Department of Natural Resources, Division of Mined Land Reclamation <br />Permit No. 77-313, to allow construction of a small, temporary bridge <br />across the back channel of the Roaring Fork River (see Drawing 1001). <br />This bridge will allow a crane to cross onto the small island and <br />construct a bent support for the conve}•or system which will cross the <br />Roaring Fork River. <br />Ide plan to place two (2) girders across the channel at the 6022 foot <br />elevation (see Drawing 1002), requiring a thirty (30) foot span. The <br />girders will be dug in six inches to provide necessary support and <br />stability. The girders will be topped with 6" x 6" x 12' timbers to <br />provide a suitable roadway. <br />The bottom of the back channel is at elevation 6020.3 feet while the <br />ordinary high water mark is at elevation 6018.5 feet. The back channel <br />fills only when the river water elevation has surpassed the ordinary <br />high water mark by 1.8 feet, The temporary bridge construction will <br />be such that the bottom of the timbers will be 3.2 feet above the back <br />channel bottom, 5.0 feet above the ordinary high water elevation. <br />The Roaring Fork River is currently at low flow stage. Because of the <br />lack of snowfall this past winter, we don't anticipate any flooding <br />problems. We would, however, like to begin and finish the construction <br />of the conveyor bent support as soon as possible in order to avoid any <br />1 <br />
