• Drainage -Most of the road is within the RSN drainage system. Three 18" culverts
along this road convey surface runoff under the road on its way to sediment ponds.
See Appendix 3-2 for intemal drainage design. For the creek crossing a dip section
with 6-36" CMP culverts encased in concrete convey low flows under the road. The
concrete surface conveys high flows across the road without eroding the road. See
Appendix 13-1 or design of drainage through and across the dip section. Straw bale
dikes are installed along each edge of the dip section to settle and filter roadway
drainage before it goes to Coal Creek. Ditches not includes in the intemal drainage
include ditches along the roadway leading to the dip section. Design for these ditches
is given in Appendix 13-1.
Surfacing -Specifics on the roadbase are unknown. The surface of the road is 3/4"
roadbase gravel.
Maintenance -The road is watered regularly during use and graded as necessary. Mg-
CI is applied to the surface once or twice a year to reduce the watering requirements.
When grading the road, the silt deposited on the dip section is graded off and the bales
are replaced as necessary.

Description -This road includes portions of the Overland Conveyor and the Unit Train
Loadout (UTL) operations area over which coal was hauled onto and away from the
UTL. The road extends from the public road near the Colorado River bridge at Cameo
along the rail spur and through the rail loop to the north end of the loop for a total length
of approximately 5500'. This road will remain as access to the property for
industrial/commercial operations.
Design and Construction -The road was installed across areas graded during
construction of the UTL and rail spur across relatively level land near the river. Minor
cuts and fills were made to cross the Coal Creek and the rail loop. The maximum
grade is 10% for 40' with the majority being less than 0.5%. The roadway width varies
from 20 to 40' and averages approximately 30'. Figure 13-2 is a typical cross section
for the design of this road.
Drainage -Most of the road is within the Overland Conveyor and the UTL drainage
system. Inside the UTL loop, runoff will be directed to Pond 1 & 2. For the creek
crossing a dip section with 6 - 30" CMP culverts encased in concrete convey low flows
under the road. The concrete surface
