Mountain Coal Company, L.L.C. Exhibit 51 West Elk Mine Lower Refuse Pile • 7.0 ROADS 7.l RealignmentofSylvesterGulchRoad The construction of the lower refuse pile required the realignment of existing Sylvester Gulch Road at hvo different locations. Initial relocation occurred at the south end of [he project early in Phase I. .4 short stretch of Sylvester Gulch Road was relocated to the east to create sufficient space for the construction of the subsoil stockpile. .4t the end of Phase 111 and prior to beginning construction of Phase IV, the realignment of Sylvester Gulch Road w•as extended further to the north [o allow coal waste to be placed above the existing alignment. A plan and profile sheet and cross-sections have been provided in Appendix M (see Figures LWP-015, LWP-OI~A and LWP-016). The alignment contains eleven horizontal curves and two vertical curves. The design contains a short section with steep grades reaching but still meets all the requirements of Rule 4.03.1(3)(a-c ). Specifics of the design can be found on sheet LW'P-019 (see Appendix M). During Phase V, portions of the SylvesterGulch road were relocated and the entire road upgraded to a haul/ access road for access to the Sylvester Gulch Facilities Area. Details of the road construction are in Exfiibit 69. To further increase the protection of the waste pile from erosion by flood events on Sylvester Gulch. oversize material (eighteen inches and larger) from stripping operations can be placed alone the east side of the Sylvester Gulch Road realignment. See Section?.I. 7.2 Access Roads Following Phase Ill and prior to beginning construction of Phase IV. a section of the access road located on the slopes above the waste pile was relocated. The new alienment joined the main mine access road approximately 1100 feet to the west. A plan and profile sheet, as well as cross-sections, can be found in Appendix N (see Fieures LWP-017 and LWP-018). In order to avoid the difficultiesofconstructing stable fills on the extremely steep slopes in this very steeply sloping environment, the road template consisted entirely of cut. The original design for the access road in the "upper location", which was a steeper area, had cut slopes of I.~H:I V and a safety factor of approximately 1.4 (assuming dry• conditions). The constructed design was located in the "lower location" and was cut in less steep terrain under dry conditions. Therefore. [he constructed access road had a higher factor of safety than the original desien in the "upper location". The revised access road design was approved on August ?8, 1989 under Minor Revision No. 66. The access road drainace system is shown on the Phase I V figure The drainage ditches are'_ feet deep with 3H:1 V side slopes. The ditch was constructed to handle the 100-year design Flow. Flows were routed [o Sylvester Gulch. The access road was cross-sloped at a one percent grade so that water collecting in the road will drain into the ditch as shown on [he access road cross-sections(see Figure LWP-018). 7.3 Relocation of the Waterline A previously existing hvo-inch diameter steel waterline. known as the Tony Bear Pipeline, and owned entirely by MCC followed the existing alignment of the Sylvester Gulch Road and passed beneath the proposed waste pile. Prior to Phase l V, the line was relocated and the portion extending beneath the refuse pile was plugged and abandoned. The water from the Tony Bear Pipeline was rerouted upstream of the LRP to discharge into Sylvester Gulch. This permitted the maintenance of existing water rights (see Table • 33 of the MRP). 34
