<br />third haulroad, Middle Moffat Haulroad, extends from the midslope portion <br />of Moffat to the Lower Moffat Haulroad. The profile for this road is shown <br />on Exhibit 3.5-6. <br />There are three light use roads at the Edna Mine. The Trout Creek <br />Road located near the Moffat Pond is described in Section 3.6.5. The West <br />Ridge - Center Ridge Light Use Road extends from the West Ridge Road to the <br />West Ridge and Center Ridge Ponds. The Scrap Yard Road extends from the <br />North Haulroad to the Scrap Yard located south of the metering substation. <br />These roads are show on Exhibit 3.5-1. <br />These roads will be maintained and reclaimed according to the <br />standards set forth in Section 3.5. Culvert placement for these roads are <br />shown on Exhibit 3.5-22. <br />3.6.7.9 soQimantatioa YonBa <br />All sedimentation ponds, except for the Moffat pond and Facilities <br />• pond were constructed during the interim program. The interim program <br />sediment control structures were designed to the performance standards in <br />effect at the time they were constructed. Design of these ponds and size <br />calculations are provided in Section 4.6.4, 4,6.5 and 4.6.6. At the <br />present time, there is no indication that these structures do not meet the <br />effluent limitations in effect now. Appendix 3.6-A shows the monitoring <br />results for these ponds. Should the discharge from these structures fail <br />to meet effluent limits in the future, they will be redesigned to meet the <br />performance standards and design criteria in effect at that time. <br />The Moffat and Facilities ponds were constructed under the permanent <br />program. Design of these ponds and size calculations for These ponds are <br />provided in Section 4.6.1. <br />3.6.3 C071L HARDLINO 9TRIICTIIRS9 <br />Coal is hauled from the active mining area to the hopper area by <br />trucks. The coal is then either placed in the coal stockpile or dumped <br />into the hopper. The stockpile is used in the event of breakdowns or to <br />• facilitate coal blending.
