The haul road will be surfaced with the surfacing material from the relocated section of Haul Road B, or granular <br />spoil material. The surface dressing, approximately 6 inches in depth, will be compacted and tested per the above. <br />In order to accommodate hauling of stoker coal from Tipple 2 to the stoker coal stockpile an existing road will be <br />upgraded to a coal haul road. The location of Haul Road C is shown on Map 24, Surface Facilities. It is anticipated <br />that 100 ton haul trucks will be used. <br />The existing road, formerly the county road, is an access corridor used by Colorado Yampa Coal Company. CYCC <br />has used and maintained the road since the mid-70's. As such no new surface disturbance will be requved for <br />upgrading the road. <br />The existing road surface is approximately 40 feet in width and runs along the toe of the slope. A ditch that mns <br />parallel to the road intercepts the upland drainage. The ditch will be triangular, and will be stabilized by planting <br />grass in the bottom and on the side slopes. This drainage flows to a culvert where it is passed under the road and <br />flows into Foidel Creek. The design for the ditch can be found in Exhibit 8. A rock filter dam will be constructed <br />downstream from the outlet of the culvert. The culvert will be 12 inches in diameter, and the design specifications <br />can be found in Exhibit 8. The ditch and culvert design information can be found on pages 8-14 through 8-19 of <br />Exhibit 8. The inlets and outlets will have rock headwells, or similar type protective devices. The location of the <br />ditch and culvert is shown on Map 24. <br />The existing road's sub base will be utilized and two six lifts of 6" minus pit run will be placed on this sub base. <br />Each lift will be compacted with a vibrating compactor or similar equipment. A two inch layer of minus 1'/~" <br />crushed gravel will be applied as a surfacing layer. This layer will be compacted as per the above. Refer to page <br />2.05-67 for the size distribution of this material. The surface layer will be crowned to provide drainage off of the <br />road. <br />The overall grade of the road is not steeper than 10%, and there aze no sections that exceed 15%. A view of the <br />road in the field indicates that the road is relatively flat (approximate overall grade of S 1H:1 V. The road should not <br />adversely impact any endvonmental values of the area. <br />Once the road is no longer needed it will be reclaimed by grading it so it blends in with surrounding topography. <br />Topsoil is not available for reclaiming the road, therefore, the best available plant growth media will be utilized. <br />The media will be analyzed for nutrients and the appropriate fertilizer will be applied. It is anticipated the road will <br />be in use for thirty or more years so it is impossible to determine fertilizer requirements at this time. <br />A segment of Haul Road B will be relocated to allow for the installation of the prep plant and associated facilities. <br />The relocated section of the road will be wnstructed per the requirement specified above for Haul Road B, except that <br />no fill material will be hauled in to crezte an embankment. The base and surfacing material will be as above. An <br />additional minor modification to the Haul Road B is constructed to accommodate stoker truck traffic at the prep plant. <br />A driveway is established south of Haul Road B and west of the prep plant. The driveway enables trucks accessing <br />the prep plant stoker stockpile to tum around after entering the mine from the main entrance east of the office. The <br />driveway is shown on Map 24. A 12"minimum diameter pipe is installed to ensure that the driveway does not disrupt <br />the drainage pattern established in the area. <br />Culvert Relocation <br />The culvert (E-2-B), under the original Haul Road B, has been relocated under the segment of the haulroad that was <br />relocated during the construction of Pond E. Due to the final site grading, two culverts will be placed under Haul <br />Road B. The additional culvert receives drainage from the segment of the prep plant area that previously flowed <br />• back to the original culvert E-2-B. However, to keep the original design, a IS inch culvert is shown also <br />'~~~°~®~~'~ APR 2 4 2006 <br />Permi[ Renewal No. 3 2.05-69 12/10/98 <br />
