Utah International Inc. discusses those roads within the proposed permit area that have been perma- <br />nently abandoned (Appendix O). <br />3.7.2 Haulroads <br />Haulroads are those roads that are used to transport coal or waste. Haulroads are located, designed, <br />and constructed to carry the volume and load of traffic at the Trapper Mine. In accordance with <br />applicable reclamation standards, road water runoff that mingles with runoff from other mining or <br />reclamation disturbances is controlled by sedimentation ponds to minimize its effects on water quality, <br />fish and wildlife. All haulroads are surfaced with appropriate materials as discussed in Section 3.7.2.4. <br />Haulroads are maintained nearly continuously when coal or waste is being hauled. When no longer <br />required, the haulroad areas are reclaimed. <br />Haulroads do not restrict movement of wildlife. During migration, wildlife such as elk and deer cross the <br />haulroads regularly. Infrequently has big game been struck by mining equipment at the Trapper Mine. <br />Due to the current 40 mph speed limit and good visibility, it is anticipated that this will remain as such. <br />The design and construction practices of existing haulroads at the Trapper Mine are certified by a reg- <br />istered professional engineer or a professional registered surveyor and the same will be true of future <br />haulroads. During the life of the permit, several new roads will be constructed. The possible locations <br />of these roads are shown on Map Mg. Actual locations may vary within 200 feet, but the roads will still <br />comply with the regulations, the remainder of this Section, 3.7.2 and Section 1.4. The year a haulroad <br />is actually constructed may vary from that indicated on the maps by + two years. <br />3.7.2.1 Location <br />The mining areas at the Trapper Mine are located on the north slope of the Williams Fork Mountains. <br />Mining occurs near the crest of the mountain and extends down the slope. The power plant's receiving <br />facilities are located near the base of the mountain. To provide access between the mining areas and <br />the receiving facilities, slopes up to twenty percent must be negotiated. To accomplish this, haulroads <br />are located to take advantage of the topography. <br />3-160 <br />PRy <br />gl2t 109 <br />
