Federal law. The locations of existing and proposed haul roads are shown on Exhibits 12-2
and 12-3.
Location. At the Nucla Mine, approximately 0.23 total miles of haul roads have been
constructed on lands previously disturbed by mining and reclamation operations and 0.08
miles of haul road have been constructed outside of the disturbed area, respectively (see
Exhibit 12-2). At the Nucla East area, approximately 0.08 total miles of haul roads will
be constructed on lands proposed to be disturbed by mining and reclamation operations and
0.13 miles of haul road will be constructed outside of the disturbed area, respectively
(see Exhibit 12-3).
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 Peabody's topsoil salvage plan.
The location will be partially limited by the grades of the existing or postmining areas.
Stream fords will not be used during construction of roads unless approval is first
obtained from the regulatory authority. The existing and proposed haul road profiles and
typical cross section are shown on Figures 13-1, 13-2, 13-3, and Exhibits 13-20 and 13-21.
Construction summaries and certifications are presented in Attachment H.
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 CMLRD 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.
The horizontal alignment will be consistent with the existing and postmining topography
and will be coordinated with the vertical alignment to ensure that the roads will not
