Rd 65 to its terminus at the cut slope above the bathhouse used for conveyor maintenance, (iv) the <br />alluvial road past the double gate to the wells, (v) the road to the north of the slot storage bench and <br />(vi) the road to the B -Vent shaft. These roads meet the requirements of Rule 4.03.3. <br />A light use road approximately 2410 -feet long and 12 -feet wide was constructed from the existing <br />Deserado Mine Haul Road to the B -Vent Shaft (Maps 151 and 152). Similarly, 6000' of light use <br />roads connect County Rd 65, RDH -3, SH -1, SH -2, and B -Vent Shaft #2 to the haul road. These <br />light use roads are graveled to allow all weather access to these sites (Map 155). <br />Construction specifications were in accordance with applicable sections of the regulatory agency <br />design criteria listed above. Each construction contract document bound the contractor to the <br />applicable sections of the regulatory documents pertaining to construction. The initial construction <br />activity consisted of clearing and grubbing all woody vegetation from the construction right -of -way. <br />The material cleared and grubbed was piled in areas off the right -of -way so as to be useful habitat in <br />promoting wildlife. Next, topsoil was removed and stockpiled close to the access road and in areas <br />not affected by erosion. Such construction method will be followed for all roads except light use <br />roads where topsoil removal will not take place except as necessary per section 4.03.3(3)(f). <br />The stockpile locations and volumes are shown on the plan and profile drawings. Following removal <br />of woody materials and topsoil, grading operations for cut and fill sections started for the road and <br />conveyors. Culverts were installed and bedded in low areas along the slope of the existing drain <br />channel. Additional culverts to satisfy grade requirements were installed during this operation, with <br />proper collection drains on the downstream side leading to natural drainage basins. Runoff <br />calculations are discussed in another section of this permit application. <br />After the grading was completed, the drainage ditches were installed, surface of the roadway <br />graveled and cut and fill sections topsoiled with the material taken from the stockpile. During all the <br />above operations, the design engineer's construction inspectors monitored the work to assure <br />compliance with all regulatory agency requirements. Soils test for compaction and gradation were a <br />part of the inspection activity. Access and maintenance roads are maintained by periodic regrading <br />of the gravel surface and regraveling as required. Ditches and culverts are cleared periodically to <br />assure proper drainage. Since the maintenance road receives very little traffic, dust control is not <br />used. The access road surface is watered and treated as required for dust control. <br />Culverts and ditches were designed as discussed in Section IV.D.2. Drainage areas for culverts <br />and ditches are shown on Maps 23 and 86. Construction methods were similar to that discussed for <br />the haul road. Only authorized personnel use the access road to the explosives storage area. <br />At the end of the mine life, culverts will be removed or buried on site, the gravel surface mixed fill <br />during the regrading to approximate original contour, then covered with topsoil and reseeded. <br />Technical Revision #67 (8/2009) IV -3 2 <br />
