Section B
The following findings and specific approvals are required by Rule 4.
I. Roads - Rule 4.03
A. Haul Roads
1. There is one: haul road at the West Elk Mine and is shown on
Map 53 . This road provides the main access to the site from
Highway 133. Designs can be found in Exhibit 51, Dower Waste
Coal Disposal Area. The plan and profile of grade and road
centerlines, ditch flowlines, and cross sections for roads are
provided in Exhibit 43. A discussion of the haul road is found
in Section 2 .05.3 in volume 1 of the permit document. The
designs are in compliance with Rules 2.05.3 and 4 .03.1.
2. This road will be reclaimed upon closure of the mine when the
road is no longer necessary.
B. Access Roads
1. The West Elk Mine has four access roads which are shown on Map
53. A discussion of the access roads can be found in Section
2.05.3 in Volume 1 of the permit document. These are the stack
tube storage road, silo storage road (formerly the haul road
until the stack tubes cut off access) , middle mine facilities
road, and Sylvester Gulch fan road. The designs are in
compliance with Rules 2.05.3 and 4 .03.2.
2. All of the roads will be reclaimed except the Sylvester Gulch
fan road, which is owned by Atlantic Richfield and will provide
access to the fan site and areas to the south.
3. The upper waste pile includes an access road to be used to
transport waste to the site. The road is planned to be
2,500 feet long, a full cut-section, gravel surfaced road with
grades up to 10 percent. Because of inaccessibility, due to
weather, to the proposed road alignment at the time of the
upper waste :pile revision, a geotechnical investigation of the
road corridor has not been completed. This investigation would
include a reconnaissance geologic map with emphasis on slope
instabilities and drainage characteristics. Based on this map,
a preliminary access road cut-slope stabilization and drainage
design will :be developed. Once approved by the Division,
initial construction will be as a pioneer road with minimal
excavation. This investigation and final design will be
completed as the road is excavated. The upper refuse pile is
not proposed for this permit term; therefore, construction of
the road is :not proposed. More information is included as
Exhibit 50 in the permit application.
C. Light Use Roads
1 . The West Elk Mine has several light-use roads at the site.
They are around the southern and eastern perimeter of MB-2R and
around the base of lower refuse pile, above the facilities area
and on Jumbo Mountain to access monitoring sites and the water
tank, and tha Lone Pine Gulch fan road. The designs, except
for some preexisting roads, are in compliance with Rules 2 .05.3
and 4,03 .3.
