one Support Facilities <br />The Disturbance Map 5-2 shows the location of all of the mine facilities and each structure is labeled <br />according to its intended and current use. All facilities have been designed, constructed, and <br />maintained in accordance with Section 4.04 of the performance standards. Each facility is designed <br />to be mobile or portable. No permanent facilities will be constructed. <br />Prior to construction of the facilities, all topsoil was salvaged and stored (see 2.05.3(5) and Map 5- <br />1). The facilities were located and constructed according to the particular specifications for that <br />structure. There are no specific design criteria for the particulaz structures other than criteria <br />assigned in designing the sediment control system and the air pollution control measures, both of <br />which are described in this section. <br />Fadsting Facilities <br />There aze no regulated existing structures on-site prior to mining and as a result, there are no <br />compliance plans, or designs which are required by this section. <br />Roads, Conveyors, and Rail Systems <br />One haul road from the pit to the staging area as shown on Map 5-1 has been constructed. The haul <br />road described below has been designed to comply with the design specification of Rule 4.03.1. The <br />road is approximately 4,000 feet long and the overall grade will be five percent (5%). <br />• Haul road specifications are contained in Appendix 5-1 which includes profiles and other <br />specifications such as width, gradient, surface specifications, cut and fill information and culvert and <br />ditch information. Specific discussions on the care and maintenance of the outslopes of the haul road <br />have also been described in Appendix 5-1. Road designs have been reviewed and certified by a <br />registered professional engineer as set forth in Appendix 5-1. Oakridge's haul road has been <br />designed to ensure that the construction, maintenance and post-mining conditions of the haul road <br />into and across the site will control erosion, siltation and the pollution of water entering and leaving <br />the azea which the road will cross. The slopes and culverts of the road were designed and aze <br />maintained in such a way to prevent additional contributions of suspended solids to run off outside <br />the permit area. In addition, there are no alternative design criteria or specifications other than the <br />proposed culvert spacing which deviates from the criteria set forth in Rule 4.03.1. <br />A section of the haul road crosses over the box cut spoil area which filled a section of Carbon <br />Junction Canyon within the permit azea. The watershed above this azea is less than one squaze mile. <br />There are no fords of ephemeral streams. No steep slope cuts are involved with the subject haul <br />road. <br />The surfacing of the haul road has been described in Appendix 5-1. Initially, a layer of bedrock was <br />established for the haul road and covered with crushed rock and gravel according to the schematic in <br />Appendix 5-1. <br /> <br />TR09, TR11(v1.0) 5-3 Revised 3/98, 8/02 <br />
