Section - 2.05.3 <br />Roads <br />Designs and as-built configurations for all mine roads effect compliance with applicable provisions of <br />Rule 4.03 and 4.04. Specifications for each road are summarized or referenced in the following <br />sections. Unless specifically discussed or referenced, alternative specifications are not necessary since <br />road designs comply with applicable regulatory standazds. In those limited areas where alternative <br />specifications axe necessary due to cut ox Fill requirements, geotechnical stability considerations are <br />addressed by discussion ox reference. Because those roads requiring certification per Rules 4.03.1 <br />(1)(d), and 4.03.1 (f)(i) are components of larger construction projects, road certifications are included <br />in Exhibits 2.05-E2, Geotechnical Design and Stability Analyses and 2.05-E4, Mine Development <br />Waste/Coal Refuse Facility Design. Any alteration or relocation of natural drainages and <br />requirements fox inlet/outlet protection Fox road culverts in conjunction with road construction <br />requirements is addressed in the subsequent sediment control section. The only stream ford which <br />exists on any mine road is an existing ford on the Elk Creek/Hubbazd Creek powexline road as <br />discussed under the description of this road. <br />Portions of the main entrance, Sanborn Creek Mine, and West Valley haul roads and other roads axe <br />within 100-feet of the outside right-of--way line of State Highway 133. By letter dated February 28, <br />1991, the Colorado Department of Highways provided Somerset Mining Company with permission <br />fox the proposed permit area and associated roads within the permit area to be within less than 100 <br />feet, measured horizontally, of the highway right-of--way. In addition to the required Highway <br />Department approval; all mining and related activities will be conducted within the permit area on <br />private and public lands where the public has never had access or where public access has been <br />limited; the Union Pacific Railroad right-of--way, tracks, and related facilities he between the mine and <br />the highway; and the proposed mining and related activities should not adversely impact public <br />interests. <br />Because those roads requiring certification per Rules 4.03.1(1)(d) and 4.03.1(f)(i) axe components of <br />larger construction projects, road certifications axe included in Exhibits 2.05-E2, Geotechnical Design <br />and Stability Analyses, and 2.05-E4, Mine Development Waste/Coal Refuse Facility Design. <br />Mine Entrance Haul Road -The entrance road which runs from State Highway 133 to the Elk <br />Creek coal handling, support, and ancillary facilities area, is classified as a haul road since it is utilized <br />for truck haulage of coal to and from the mine. For purposes of characterization and discussion, this <br />road can be segregated into four segments. For all road segments, road width and grade aze <br />appropriate for the volume of traffic and weight and speed of vehicles that use the road as indicated <br />by safe operation and miniu~al maintenance over a period of many years. The speed limit fox this and <br />all mine roads is 15 miles per hoax and the road is designed and constructed to provide a minimum <br />turning radius of 50-feet. The entire toad is within the mine disturbance area as defined by Rule <br />4.05.2(4) and many of the performance standards under Rule 4.03 are, therefore, not applicable. <br />Road plan and profile configuration is shown by a Facilities Detail Map, (Map series 2.05-M3x). <br />The first segment of the mine entrance road begins at the edge of the right-of--way for State Highway <br />133, crosses over the railroad right-of--way, passes on the uphill side of the coal storage silo, and <br />TR-44 2.05-24 Revised October 2003 <br />
