the U.S. Army Corps of Engineers under Nationwide Permit No. 3. Approximately 75 cubic yazds of road base and
300 cubic yazds of spoil material were placed as cover for the culvert extensions and rock check dams were
placedacross the new extensions, on the east and west sides of the crossing. The actual road crossing remains in its
original location over the original culvert location. A 12-inch minimum diameter pipe was installed during
construction of the Haul Road B Driveway, to assure that the driveway does not disrupt established drainage patterns
in the azea.
Hauh•oad B was constructed on compacted spoil material and selected spoil material was also used as fill in low
azeas. This is a previously disturbed area, and as such, no topsoil was available during either road construction or
relocation for salvage. Road construction involved removal of organic material from road foundation azeas,
compaction of the remaining material where fills were not required (the Haulroad B relocation did not require any
fill placement), and controlled placement and compaction of spoil material for required road fills. Lifts did not
exceed 36 inches in thickness, and were compacted and tested per AASHTO.T-99 or similar specifications.
Hauhoad B is surfaced with approximately 6 inches of compacted gavel or granulaz spoil material.
HC. Haulroad B Extension
The Haulroad B Extension, approved under MR 01-175, is a short segment of haulroad n,nn;ng on the southwest
side of Pond D and connecting Haukoad B-1 and the Refuse Pile Haulroad, as shown on Map 24, Surface
Facilities. This road segment was designed and constructed to the same standards as Haulroad B-1. The centerline
road profile for the Haulroad B Extension is included as part of the Haulroad B-1 profile, and the profile and typical
cross-sections aze shown on Map 30, Road Profiles and Cross-Sections. During 1996, the road was upgraded
through placement of approximately 4 inches of Class VI base course and 6 inches of pit run gravel.
IID. Haulroad A
Haulroad A was previously approved, permitted, and certified under CYCC Permit C-81-071 (formerly 179-77).
Haulroad A extended from the old west entrance (Routt County Road 27) to the road intersection east of the current
scoria storage azea. Design information for Haul Road A is presented in Exhibit 250 and a profile for the
remaining portion of the road is shown on Map 30, Road Profiles and Cross-Sections. TCC does not currently use
any portions of Haul Road A for haulage.
IIE. Haulroad C
Haukoad C, formerly a portion of the county road, is an access corridor previously used and maintained by CYCC
since the mid-70's. In order to accommodate hauling of stoker coal from Tipple 2 to the stoker coal stockpile, the
existing road was upgraded to a coal haul road. Haulroad C extends from the Tipple 2 road intersection due south
of Pond C to the current railroad crossing where it connects with Haulroad B-2. Because it was a previously
distwbed azea, no new disturbance was required for the upgrade and no topsoil was available for salvage. The
overall grade of the road is not steeper than 10 percent, and there aze no sections that exceed 15 percent. The
location of Haul Road C is shown on Map 24, Surface Facilities. The centerline profile for Haulroad C and typical
haulroad cross-sections aze shown on Map 3Q Road Profiles and Cross-Sections.
In conjunction with the road upgrade, a ditch was established parallel to the road to intercept upland drainage. The
ditch is triangulaz, in cross-section, and was stabilized through vegetative plantings on the bottom and sideslopes of
the ditch. Drainage from this clean-water diversion flows to a 12-inch culvert, where it is passes under the road and
into Foidel Creek. The culvert inlet and outlet are protected by rock headwalls, or similar erosion protection. A
rock filter dam was constructed downstream from the outlet of the culvert. The location of the ditch and culvert are
shown on Map 24, Surface Facilities, and ditch and culvert design information is provided in Exhibit 8.
The original road was approximately 40 feet wide and ran along the toe of the slope. During road upgrade planning
and constmction, it was detemuned that the existing road sub-base was adequate, therefore, the road upgade
involved placement and compaction of two six-inch lifts of 6-inch minus pit run rock over the existing sub-base.
Each lift was compacted with a vibrating compactor or similaz equipment. Fills were placed, compacted, and
