RULE 2: Permits <br />Page 2.05-26 <br />TR-21 Revised: 2/17/2021 <br /> <br />Access Roads <br />Access roads are frequently traveled roads which are not used for the transportation of coal. Access road <br />preliminary designs and construction drawings are certified by a qualified registered professional <br />engineer. <br />An existing road provides access from Highway 12 for ranching and timbering up Lorencito Canyon. This <br />road will be upgraded to a haul road from Highway 12 to the Jeff Canyon haul road. From there it will be <br />used as an access road to the office area. This will provide access for personnel and equipment. The <br />access roads are designed to American Association of State Highway Transportation Officials Policy on <br />Geometric Design for Local Rural Roads. This access road is shown on Map 2.05.3-1. <br />Alignments follow existing roads, ridge lines, and stable slopes when possible; and follow the topography <br />so as to minimize cuts and fills and avoid flood plains. Any crossings of drainages will be done at right <br />angles. Except for crossings, no segments of access road are located in the channel of an ephemeral, <br />intermittent, or perennial stream. Intermittent or perennial natural drainages will not be altered or <br />relocated. No unique, endangered, or special environment or cultural resources are known to be impacted <br />by the road system. <br />Access road design will accommodate the needs of specific uses of the road. The design maximum speed <br />is 25 miles per hour. Grades will be limited to 15% for limited distances prescribed by the regulations. <br />A 20-foot wide travel way is proposed for the main access road. The travel way is crowned (5%), ditched <br />adjacent to cuts, and has culverts or swales when necessary to prevent ponding. Typical cross sections are <br />shown in Figure 2.05.3-14. <br />Vegetation will be cleared for no more than the width needed for the roadway, drainage control, and any <br />cut and fill. Topsoil will be removed from road cut and embankment footprints and stored for use in <br />reclamation and as a vegetation growth medium for cut and fill slopes. <br />Cut slopes will not be steeper than 1.5h:1v in unconsolidated materials or 0.25h:1v in rock. In areas of <br />steep side slopes, the road alignment will be shifted so that the entire road width rests on the cut benches. <br />Embankment material will be free of organic matter, peat, or other unsuitable (acid -producing) materials. <br />In the event an embankment is required on side-slopes greater than 33%, the embankment will be plowed, <br />stepped, or keyed. Embankment slopes will not be steeper than 1.5h:1v unless the material consists of a <br />minimum of 85% rock, in which case the slopes may be placed up to 1.35h:1v. Embankment materials <br />containing less than 25% rock larger than 6 inches will be placed in uniform layers not exceeding 12 <br />inches before compaction, and compacted within acceptable levels of moisture content. Material <br />consisting of large-size rock will be placed in uniform layers not exceeding the average size of particles, <br />lifts not in excess of 36 inches, and placed in a manner to minimize voids, pockets, and bridging. The <br />final layer will contain material which has less than 25% rock larger than 6 inches in largest dimension in <br />a uniform later not exceeding 12 inches. <br />Technical Revision 21 proposed an access road to access drill location LC-17-20. The access road will be <br />located off a haul road and wil l be approximately 30 feet long by 14 feet wide.
