Haul Roads
The following describes the design and construction of haul roads at the NHN Mine. See Map
2.05.3(3)-3 for full detail on the road alignment and profiles for all haulage roads. The names of
the haulage roads which will be utilized are the East Haul Road, the West Haul Road and the
Northwest Haul Road. Map 2.05.3(3)-3 additionally shows typical construction cross sections of
the haulage roads and shows a table which details the widths of the haulage roads. Appendix
2.05.3(3)-3 contains the construction as -built for the West Haul Road (Section 0+00 to 10+52)
including Map 2.05.3(3)-4. Haul roads are located within 100 feet of the Montrose County road
right-of-way. As required by DRMS regulations, WFC requested Montrose County for a waiver
to disturb within 100 feet of the County right-of-way. Montrose County has given such a waiver
limiting the disturbance within 25 feet of rights of way as a part of the Special Use Permit.
Appendix 2.05.3-1 includes a copy of the Montrose County's resolution to approve the Special
Use Permit.
General Requirements. WFC will construct, maintain and reclaim haul roads to minimize
erosion and siltation, air and water pollution and damage to public and private properly. To the
extent possible, using the best technology currently available, haul roads will not cause damage
to fish, wildlife, or related environmental values and will not cause additional contributions of
suspended solids to stream flow or to runoff outside the permit area
Location At the NHN Mine area, haul roads will be constructed on lands proposed to be
disturbed by mining and reclamation operations.
Haul roads at the mine site will be designed with appropriate ditches, grades and culverts to
control erosion and runoff. All haul roads will be constructed basically "on -grade". Topsoil will
be removed and stockpiled in accordance with WFC's topsoil salvage plan. The location will be
partially limited by the grades of the existing or postmining areas. The proposed haul road
profiles and typical cross section are shown on Maps 2.05.3(3)-3. Appendix 2.05.3(3)-3 contains
the construction as -built for the West Haul Road (Section 0+00 to 10+52).
Design and Construction The design of the haul roads incorporate the demand for mobility and
travel efficiency, based on the geometric criteria appropriate for the anticipated volume of traffic,
weight and speed of the vehicles to be utilized. The design and construction or reconstruction of
haul roads not within the estimated disturbed area will be certified by a registered professional
engineer, if required by the DRMS for good cause shown.
Should haul roads not within the estimated mining disturbance areas be necessary, they will be
designed and constructed or reconstructed in compliance with the following standards in order to
control erosion and disturbance of the hydrologic balance.
The vertical alignment of the haul roads will not exceed 10 percent on the overall grade.
Maximum pitch grade will not exceed 15 percent, and there will not be more than 300 feet of
pitch grade exceeding 10 percent within any consecutive 1,000 feet.
