first section. This segment of the road is approximately 900 feet long and has an average grade of
• approximately 9.0 percent and maximum grades of 10 percent.
The third segment of the West Valley haul road extends from the northeast comer of the cemetery,
along the west side of Elk Geek Canyon to tie-in with the Elk Leek Canyon road above the Elk
Geek coal stockpile. Initially, this road segment only provided temporary access for haulage of soil
material from the West Valley fill area to the Ells Creek soil stockpile and limited access to the original
pre-law Elk Geek Canyon road. With development of the Elk Geek Mtne, however, this segment
lirilts the Elk Geek Canyon and West Valley haul roads to provide full access to the Ells Geek Mme
for haulage of coal, coal refuse, mine development waste, men, equipment, and supplies. This segment
of the road is approximately 1,000 feet long with a maximum pitch grade of approximately 10 percent
over 300 feet and an average grade of 4 percent.
The Somerset Cemetery was previously accessed by portions of the main entrance road, the Elk Geek
Canyon road, and the cemetery road. Expansion of the Elk Geek coal stockpile cut-off this access at
the base of Elk Geek Canyon. The West Valley haul road now provides for public access to the
cemetery via a shoe connecting road at the east end of the second road segment. OMI has
coordinated with the citizens of Somerset to notify them of both the availability of access to the
Somerset Cemetery and the need to check in at the mine office prior to proceeding to the cemetery as
a saferyconsideration.
Drainage control for the West Valley haul road is provided by roadside ditches and cross-culverts.
The uphill ditch for the second road segment drains to a culvert crossing at the West Valley Fill
switchback, with culvert discharge flowing to the uphill ditch for the fast read segment. At the
bottom of the fast road segment, a second culven crosses under the road with the discharge passing
• through an alternative sediment control structure prior to release to the existing ditch which parallels
the railroad right-of-way The uphill ditch for the third road segment discharges through an
alternative sediment control structure to Elk Geek at the point where this segment loins the existing
Ells Geek Canyon road. Drainage design details are provided in Exhibit 2.05-E3, Drainage and
Sediment Control Plan.
Elk Creek Haul Road -The Ells Geek road is apre-law road extending from the main haul road up
Elk Geek Expansion of the Elk Geek coal stockpile cut-off direct access to the lower portion of the
Elk Geek road. Access was reestablished via the West Valley haul road. In conjunction with
construction and development of the Elk Geek Mine, the middle portion of the existing Elk Geek
road will be upgraded as a haul road to access the Elk Geek Mme facilities from the West Valley haul
road. The lower portion of the existing road will ako be upgraded as a haul road to provide direct
access from the Elk Creek Mtne co the Elk Creek coal stockpile. Road upgrades will include minor
widening, placement of new or relocation of existing culvert crossings, minor cut and fill work,
grading and compaction, and surfacing with gravel. Generally, the required upgrades will involve
existing road segments, so limited additional soil removal will occur. Anysoil removed will be placed
in the north Elk Creek soil stockpile for future use in reclaiming mine disturbance areas.
For purposes of characterization and discussion, the Elk Geek haul road can be segregated into three
segments. For all road segmenu, the designed road width and grade are appropriate for the volume
of traffic and weight and speed of vehicles that will use the road. The road will be gravel-surfaced and
approximately 30 feet wide, providing for two-way traffic over the entire road. Maximum speed limit
for this road is 15 miles per hour. Cut slopes will be no steeper than 1.SH:1V and fill slopes 1.SH:1V
or less. The entire road is within the mine disturbance area as defined by Rule 4.05.2(4) and many of
the performance standards under Rule 4.03 are, therefore, not applicable. Road plan and profile
• configurations are shown by the General Facilities Map, (Map 2.05-M1) and a Facilities Detail Map,
(Map series 2.05-M3x). Road construction materiak and designs (cut slopes, fill slopes, road gradient,
drainage, and compaction/construttion requiremenu) for the Elk Geek haul road are compatible
with previously completed and approved designs and geotechnica] analyses for the West Valley haul
road as seen in Exhibit 2.05-E4, Mtne Development Rock/Coal Refuse Facility Design.
