• existed prior to the mining operation, locations were not determined by Trapper Mine, but rather by local <br />people familiar with the area and the terrain. Generally, these roads take advantage of the topography <br />and the more stable slopes and are located out of drainage channels except where crossings are <br />necessary. This is also true of any light -use roads constructed by Trapper Mine. All light use roads in <br />service at Trapper Mine will be maintained sufficiently to minimize erosion. <br />All constructed light -use roads are field designed. Most are only 10-12 feet in width and serve single <br />lane traffic. The overall grades do not exceed ten percent, and pitch grades exceeding twenty percent <br />shall be no longer than 300 feet within any consecutive 1,000 feet. While cuts and fills may <br />occasionally be required on light -use roads, there are currently no light -use roads with cuts or fills. Any <br />future light -use roads with cut or fill sections will be identified. Light -use roads meander so as to avoid <br />natural obstructions and to take advantage of the topography thus largely eliminating the need for cuts <br />or fills. Compaction of any required embankments is limited to that necessary to insure the integrity of <br />the road. For any light -use roads constructed by Trapper Mining Inc., topsoil will be removed where <br />cuts or fills will occur. Vegetation is cleared only for the width required by the road itself. <br />The locations of light -use roads within the proposed permit area are shown on Map M-52 (Hydrology <br />Monitoring Sites). Pre-existing light use roads used for access to remote areas of the permit area on an <br />infrequent basis, primarily to access surface and ground water monitoring locations, are designated <br />separately from light use roads constructed by Trapper. <br />n <br />U <br />0 3-176 MAY 13 1998 <br />
