Excluding the <br />turn-around loop at the preparation plant, the road extends approximately 30,400 feet from the point <br />under the refuse hopper to the extreme end of the Refuse Disposal Area. Traffic on the road is <br />two-directional. Therefore, the road design utilizes the 2-lane design cross-section set forth in the <br />Bureau of Mines Information Circular-IC-8758-1977 entitled "Design of Surface Mine Haulage <br />Roads-A Manual". Haul road cross-sections are shown on Maps 67 and 68. The cut and fill slopes <br />and road surtace comply with Section 4.03.1(3). Maximum cut slopes used in unconsolidated <br />materials are not steeper than 1.5h:1v and 0.25:1v in rack. The actual cut slopes used were <br />determined during construction. Maximum fill slopes are not steeper than 1v:2h. Cross sections of <br />the maximum cuts and fills along the haul road and road and plant access road are shown on Map <br />68. The design criteria used for location, vertical and horizontal alignment are as set forth in <br />Section 4.03.1(3). The maximum grade used on the haul/plant access road was 5.8 percent and <br />the minimum curve radius used was 500 feet. <br />• Permit Rev. 4 (07/2002) IV-13 <br />
