S - 2.05.3 <br />East Yard Haul Road -The East Yard haul road, which extends from the second segment of the <br />main entrance road to the East Yard waste disposal area, is classified as a haul road due to it's use for <br />haulage of coal refuse and mine development waste. Road width and grade are appropriate for the <br />volume of traffic and weight and speed of vehicles that use the road. The road u approxuately 1,000 <br />feet long, gravel-surfaced, with a road width o[ approximately 20 feet, and a maximum pitch grade of <br />15 percent. Most of the road is cut into the hillslope with cut slopes no steeper than 1.SH:1V. The <br />entire road is within the mine disturbance area as defined by Rule 4.05.2(4) and many of the <br />performance standards under Rule 4.03 are, therefore, not applicable. Road plan and profile <br />configuration is shown by a Facilities Detail Map, (Map series 2.05-M3x). <br />This haul road is used on an occasional basis for truck haulage of coal refuse and mine development <br />waste from the waste pocket at the dump station or from the East Yard stockpile area to the East <br />Yard disposal area. The road may also be infrequently traveled by tracked dozers, wheel loaders, and <br />light vehicles for the purposes of inspecting or maintaining the disposal area., associated drainage <br />structures, or connecting drill and powerline roads. There are periods when the road is not be used <br />for extended periods. Because the road u fairly steep, access during inclement weather can be <br />difficult. During the winter, road maintenance includes snow plowing if necessaryto provide for safe <br />access. During spring snowmelt and after major precipitation events the road may be impassable, <br />however, ongoing road maintenance u normally sufficient to assure access most of the time. <br />Drainage control for the East Yard haul road consists of a roadside ditch which drains to the East <br />Yard area. Drainage control for the upper portion of the road is provided by existing drainage and <br />sediment control strtrctures for the disposal area. Drainage design detai]s are provided in Exhibit <br />2.05-E3, Drainage and Sediment Control Plan. <br />West Valley Haul Road -Expansion of the Elk Creek coal stockpile cut-off access from the maim <br />entrance road to both the Elk Cmek Canyon and cemetery roads at the base of Elk Creek Canyon. <br />• Access was reestablished by constructing a new haul road from the existing mine employee parking <br />area, past the West Valley Fill disposal area to the Someaet Cemetery, and along the west side of Elk <br />Creek Canyon to tie-in with the existing Elk Creek Canyon road. As noted in Section 2.04.4, it has <br />been determined that the Somerset Cemetery is not eligible for listing on the National Register of <br />Historic Places. In addition, road construction was planned and implemented to avoid disturbance of <br />or impacts to the cemetery. <br />For purposes of characterization and discussion, this road can be segregated into three segmenu. For <br />all road segments, road width and grade are appropriate for the volume of traffic and weight and <br />speed of vehicles that use the road. The road is gravel-surfaced and approximately 30 feet wide, <br />providing for two-waytraffic over the entire road. Maximum speed limit for this road is 15 miles per <br />hour. Cut slopes ate no steeper than 1.OH:1V (except in rock where cuts may go up co 0.3H:1V) and <br />most fill slopes at 1.SH:1V or less. The entire road is within the mine disturbance area as defined by <br />Rule 4.05.2(4) and manyof the performance standards under Rule 4.03 are, therefore, not applicable. <br />The West Valley haul road was designed by Balaz & Associates and a stability analysis for the road <br />was completed by Lincoln Devore as documented in Exhibit 2.05-E2, Geotechnical Design and <br />Stability Analyses. Road plan and profile configuration u shown by a Facilities Detail Map, (Map <br />series 2.05-M3x) and by the design drawings included in Exhibit 2.05-E2. <br />The first segment of the West Valley haul road extends from the existing mine employee parking area <br />to the switchback adjacent to the West Valley Fill. This segment of the road will be used for haulage <br />of coal refuse and mine development waste to the West Valley fill, general mine traffic, access to Elk <br />Creek Canyon and the Ellt Creek Mme, and public access to the Somerset Cemetery. This section of <br />the road was constructed as a cut-fill road across the hillslope, is approximately 1,600 feet in long, and <br />. has an average grade of approximately 8.0 percent. <br />The second segment of the West Valley haul road extends from the switchback adjacent to the West <br />Valley Fill to the Somerset Cemetery. Traffic on this segment of the road will be the same as for the <br />PR04 2.05-27 Revised Augtsst 2000 <br />
