road and the Portal access road

Main Haul/Access Road Between Highway 133 and the intersection
of the Middle Mine haul/access road and the
Main haul/access road

Refuse Pile Expansion (RPE) Access from the Main haul/access road, across
Haul/Access Road Sylvester Gulch and to RPE area.

Sylvester Gulch Haul/Access Road Between main haul/access road and the
ventilation shafts site

As coal or coal mine waste may be hauled on the above roads, all of the roads have been designed,
constructed and certified as haul roads. These as-built certifications are provided in Exhibit 8A.
There are three roads that are considered access roads only. They are the Three-Sided Building
access road, the Portal access road, and the Materials Storage Bench access road. These roads have
been certified as access roads as also provided in Exhibit 8A.

Vertical grades on the haul/access roads vary. The middle-mine haul/access road has an overall
grade of 5.68 percent. This road is paved. The new silo haul/access road has a maximum grade of
10 percent and is gravel-surfaced. The Sylvester Gulch haul/access road has been designed to have
an average grade of 7.6 percent with a maximum grade of 10 percent. This road is surfaced with 12
inches of compacted Class 6 road base.

The mine roads require relatively little surface maintenance. Holes and ruts are patched in the early
stages with a cold mix of composition similar to the original road mix. In addition to pavement
maintenance on roads, maintenance operations include shaping and sealing of shoulders, cutting
back or chemically treating weed and bush growth, maintaining ditches and drains, removing litter,
and repainting stripes. Snow and ice removal during the winter months are a roadway maintenance
priority. Parking and side areas are similarly maintained for safe and efficient use.

Light-Use Roads

A gravel surfaced light-use road has been constructed around the southern perimeter of the lower
stack tube (ST-4) coal storage pile and around the base of the lower refuse pile for occasional
construction and maintenance equipment uses. Two short roads (approximately 150 ft. long) and
associated pads have been constructed from existing mine site roads to provide access: for
emergency repair and maintenance along the C-1 conveyor, to the water tank topsoil pile, to the
switchgear buildings above the portals, and to the power-poles located along the west side of
Sylvester Gulch Haul/Access road and north of the Sylvester Gulch F-Seam fan. When these roads
and pads are no longer required for operations, the roads will be graded back to approximate
original contour and reclaimed. The road between the ROM coal stockpile pad and the product coal
stockpile has been designated as a light-use road. The overall grade of the road is 7.6 percent. The
road is surfaced with asphalt or roadbase. An existing road in the Lone Pine Gulch area was
widened and graveled as a light-use road to access the former Lone Pine Gulch fan site. This road
was left in place at final reclamation to allow continued access for the landowners and lessees of the
area and is consistent with the approved post-mining land uses of rangeland and wildlife habitat.
Light-use roads to the water tank and to the Sylvester Gulch high-voltage transmission line were
