maintenance is warranted. Design for most of this segment specifies gravel lining,but based on scour observed
larger riprap may be warranted. Please regrade the ditch and install riprap as warranted to control erosion.
• Culvert PM-3 partially blocked at outlet; cleanout required.
• The ditch segment southwest of the culverted E-1 channel(PM-7 on Exhibit 20-2, but PM-5 on 13-26.1A
"As-Built") shows minor scour; TRM or riprap installation appears to be warranted.
• A section of the road segment between Culverts PM-6 (006 Gulch Channel)and A-5 (006-S 1 Channel)
was modified/reconstructed in association with regrading of a slide affected reclaimed slope in the immediate
vicinity. Erosional scour was noted along a segment of the inside road ditch up-gradient of Culvert PM-6, which
appears to have been steepened as a result of the slide repair grading and associated road reconstruction. Please
install TRM or riprap as warranted to stabilize the ditch segment southwest of Culvert PM-6.
• The culvert near the intersection with Road"J"(PM-13)was partially constricted at the inlet end, and
needs to be repaired or replaced.
Haul Road "A"
• A couple culvert maintenance items and a ditch outlet maintenance item noted in the April complete
inspection were inadvertently not checked. Operator will need to ensure the maintenance was performed and the
Division will verify during the next site inspection.
• The dragline has been removed from the permit area. It had been stored for several years at the junction of
Road"A"and the Ridgeline Access road. Removal of the dragline will allow for reclamation grading to reduce
Road"A"and the MEHR to approved postmining specifications(to be completed this year). Initial grading to
remove the MSHA berms and define the postmine 20' travel width along a '/z mile section of Road"A"east of the
shop access had recently been performed, and a dozer was parked at the location.
Mine Entrance Haul Road(MEHR)
• The MEHR was properly maintained and in good condition. Reclamation grading to downsize the road to
postmining condition is to be completed this year. This road along with the Oil Well Road is a designated Routt
County Road, and will be reclaimed to meet Routt County road specifications for postmining use. Reclamation of
the road had not yet been initiated at the time of inspection.
Tie Across Haul Road
• Ditches, culverts, and ditch relief drains were generally in good condition. One cut slope gully was
observed which needs to be repaired. The gully location is on the north side of the road,approximately 200 feet
east of the County Road 51 junction.
Road `J"(Reduced for Postmining Land Use)
