5. Light-Use Roads to Powerline Substation <br />A light-use road and a permanent road will be used to access the substation. The light-use road will run 4,800 feet <br />to the substation and will follow the existing "fence" road. The light-use road will be designed per the <br />requirements of Rule 4.03.3, Light-Use Roads. The light-use road will be sufficiently maintained in order to assure <br />erosion control. Surfacing of the road will be adequate for the general use of the road, and during winter and <br />spring, snow removal. Access to the light-use road and substation will also require the utilization of a permanent <br />road approved by the CMLRD on February 3, 1988 (Technical Revision TR87-12; Permit C-81-071). This <br />permanent road runs 12,000 feet from Country Road #27 and is maintained under CYCC's Permit C-8I-071. The <br />roads will be maintained by TCC. Upon substation removal, the light-use road will remain as part of the approved <br />postmining use of ranch management. The light-use and permanent road are shown on Map 39, Substation and <br />Powerline Location. <br />A light-use road will be used to access a subsidence borehole meter at Mine 2 (MR89-37). The road will be <br />reclaimed upon completion of the subsidence borehole metering. <br />6. Other Light-Use Roads <br />In addition to the above light-use roads, a number of other roads of this classification are located around the <br />property. The other roads include the following: Low Quality Coal Stockpile Road, West Gate Road, Fish Creek <br />Borehole Road, Escape Shaft/Borehole Site Road, EMD Dewatering Borehole Road, and Lieske Substation Road. <br />All of these roads are shown on Map 24A and have been designed and constructed in conformance with Rule <br />4.03.3. <br />General <br />No bridges are planned with this permit revision application. All culverts with an end area of less than 35 square <br />feet will be designed to pass, at a minimum, the 10-year, 24-hour event. Should a culvert with an end area greater <br />than 35 square feet be needed, it will be designed to safety pass the 20-year, 24-hour event. The culverts have also <br />been designed and constructed to sustain the vertical soil pressure, the passive resistance, and the weight of the <br />vehicles using the road. Trash racks and debris basins will be installed where needed to avoid plugging, collapse, <br />and erosion at culvert inlets and outlets. Culverts for road surface drainage were installed as specified in Rule <br />4.03.2(4)(e)(v). These culverts cross the road at not less than a 30-degree angle, and will be protected at the inlet <br />and outlet by rock riprap, if required. The culverts are covered by compacted fill to a depth of at least l foot. <br />No natural drainage channels will be altered with [his permit revision application. AlI natural drainage channels <br />will be crossed using culverts of adequate size, so as not to affect the normal flow or gradient of the stream. <br />Drainage from the access/haulroad will meet the requirements of Rule 4.05. The roads have been constructed and <br />will be maintained to minimize erosion. The water-control systems have been designed to safely pass, at a <br />minimum, the peak runoff from a ] 0-year, 24-hour precipitation event. <br />All vegetative material and topsoil will be removed from all embankment foundations during construction to <br />increase stability. Topsoil was and will be stockpiled in accordance with Rule 4.06.3 for use in final reclamation <br />operations. Embankments are not steeper than 1v:1.5h. Cut slopes will not exceed the above-specified standards. <br />Temporary check-dams, diversion ditches, etc., were built, as required, during road construction to maintain water <br />quality standazds throughout the construction period. All cut slopes will be seeded to aid in establishing vegetation <br />and to minimize erosion. All embankment slopes have been mechanically stabilized and will be seeded to aid in <br />establishing vegetation and to minimize erosion. Mechanical stabilization consisted of furrowing and "cat- <br />tracking". The stabilized slopes will be broadcast seeded during the first appropriate planting season. <br />Unless otherwise approved by the CDMG, TCC will reclaim all roads on completion of active mining operations. <br />Natural drainage patterns will be restored, with all culverts removed. Roadbeds will be rounded and shaped to <br />PR06-07 2.05-74.2 11/27/06 <br />
