• were any bridges planned for the portions of the Lorencito Canyon haul road that cross
the perennial portions of the canyon's stream, or the drainages tributary to the canyon.
The response was that no bridges were planned, but that culverted fords are proposed in
some cases.
Section 4.03.1(2)(c) cleazly states "Fords of perennial streams shall not be approved." As
such, the Division cannot approve of any haul road fords, culverted or otherwise, of
Lorencito Canyon's perennial reaches. Please revise the application to reflect this.
137. The applicant's response did not fully address the Division's concerns. It is understood
that haulage of raw coal from the mine to the New Elk processing facility will not occur
over Colorado Highway 12. This was not a concern. What the Division is concerned
with, however, is the volume of traffic entering and leaving the highway at the mine
access road junction during mobilization of the equipment described on page 2.05-1 of
the application. This equipment includes continuous miners, roof bolters, scoops,
conveyors, mantrips, graders, loaders, dozers, haul trucks, drills, and water trucks. The
Division is also concerned with the volume of traffic that will occw during construction
of the railroad spw, the loadout facility, the portals and the support buildings.
Ow concern is that during the construction and equipment mobilization phase of the
operation, there may be a sufficient volume of traffic entering and leaving the highway
at the mine access road junction that the State Department of Highways (or Las Animas
• County) may request some modification to the highway for the protection of public safety.
Please state whether the Colorado Department of Transportation, Las Animas County, the
Colorado Highway Patrol, or any other agency that may be chazged with the protection
of public safety along the State Highway has any concerns with the proposed volume of
traffic that the Division anticipates occurring dwing the construction and equipment
mobilization phase of the operation.
138. Section 4.03.2(1)(f)(i) of the Boazd's Regulations requires a certification report be
submitted to the Division upon completion of construction of any access road. This
regulation requires the certification to state that the road has been constructed as designed
and in accordance with approved plans.
This means that the Division must have access road designs to review and approve dwing
the mine permit application stage, so the certification report (the certified "as-built") can
state that the access road was designed and constructed as approved by the Division.
Figwe 2.05.3-8 depicts a 10% side slope but fails to indicate for what type of road.
Should the Division assume this applies to all roads or to a specific type of road? Please
clarify and/or correct. (ICAG)
A plan view of the access road superimposed on the existing topography (Maps 2.05.3-1
and 2.05.3-3) is sufficient to determine the proposed width of the Lorencito Canyon
• access road, but is insufficient for determining the proposed gradient. Please provide
designs for the access road that have the proposed road gradients indicated on them.
