S~ - 2.05.3 <br />from the Ells Creek Mtne surface facilities disturbance area, in a new soil stockpile <br />• constructed on the east side of Elk Creek, near the northern limit of the new mine <br />disturbance area. Projected stockpile capacity is approximately 65,200 (18,600 ey <br />from existing stockpile, 46,600 cy soil salvage from Elk Creek Mme disturbance <br />areas) cubic yards and will be verified by survey following completion of soil <br />relocation stockpiling activities. Compliance with applicable design and stability <br />requirements is addressed by the Slope Stability Analysis for Elk Creek Mute Portal <br />Bench Fills and Soil Stockpile (Montgomery Wasson, 2000). Additional details on soil <br />material handling and storage are provided in Section 2.05.3(5). <br />Roads <br />Designs and as-built configtuations 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 contp]y with applicable regulatory standards. In those limited areas where alterative <br />specifications are necessary due to cut or fill requirements, geotechnical stability considerations are <br />addressed by discussion or reference. Because those roads requiring certification per Rules 4.03.1 <br />(1)(d), and 4.03.1 (f)(i) are componenss of larger construction projecss, 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 for inlet/outlet protettion for road culverts in conjunction with mad construction <br />requiremenss is addressed in the subsequent sediment control section. The only stream font which <br />exists on any mine road u an existing font on the Elk Creek/Hubbard Creek powerline 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 are <br />within 100-feet of the ousside 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 />for the proposed permit area and associated roads within the pemmt area to be within less than 100 <br />feet, measured horizontally, of the highway right-of-way. In addition to the required Highway <br />Deparunent approval; all nuning 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 lie 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) are components of <br />larger construction projecss, road certificauons are included in Exhibiss 2.05-E2, Geotechnical Design <br />and Stability Analyses, and 2.05-E4, Mute 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, u 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 are <br />appropriate for the voliune of traffic and weight and speed of vehicles that use the road as indicated <br />by safe operation and minimal maintenance over a period of many years. The speed limit for this and <br />all mine roads is 15 miles per hour and the road is designed and constructed to provide a minimum <br />taming radius of 50-feet. The entire road is within the mine disturbance area as defined by Rule <br />4.05.2(4) and manyof the performance standards under Rule 4.03 are, therefore, not applicable. Road <br />• plan and profile configuration u 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 <br />State Highway 133, crosses over the railroad right-of-way, passes on the uphill side of the <br />coal storage silo, and <br />PR04 2.05-24 Revised May2001 <br />
