III. COMMENTS -COMPLIANCE
Below are comments on the inspection. The comments include discussion of observations made
during the inspection. Comments also describe any enforcement actions taken during the
inspection and the facts or evidence supporting the enforcement action.
This was a partial inspection of the mine site focusing on
maintenance issues identified in the previous inspection, surface
water/road drainage issues, and revegetation/shrub establishment.
The inspection was conducted by Dan Mathews of the DMG Grand
Junction Office, 2148 Broadway #C-5, Grand Junction, CO 81503,
[phone]. Inspector was accompanied by Michael Altavilla of
SCC. The single dragline was removing "A" Pit overburden at the
time of the inspection, and coal was being loaded from the south
end of "B" Pit. A coal shot occurred during the inspection, with
required safety precautions observed.
Weather at the time of the inspection was clear, warm and dry.
Records on file at the mine office indicated that late July and
early August had been quite wet, with over 1 inch of rainfall
recorded at the mine entrance weather station continuous recorder
the last four days of July, and 2.09 inches recorded between August
1 and August 13. Records indicated intense thundershower type
storm events totalling .6" on August 10, and .4" on August 6.
Roads Rock checks along the Mine Entrance Haul Road (MEHR) still
require maintenance. The slide area along the MEHR appears to have
been satisfactorily repaired. The ME-5 sump had recently been
cleaned out.
Recent heavy rains have resulted in rilling and deposition of rock
and sediment in several locations on the road surface, as well as
scouring of roadside ditches along upper segment of Road G, above
Sediment Pond 005. Drainage from eroded road surface and ditches
on upper segment of road was routed through Sediment Pond 005.
Clean-up and grading of road surfaces and ditches will be
necessary.
Stock Pond T-22 was completely filled with sediment and will
require cleanout, and riprap on the T-22 spillway was washed out
and will need to be replaced. Culvert G-5 was approximately i/2
full of sediment and will need to be cleaned out. The steep ditch
segment on either side of the G-5 Culvert outlet on the west side
of Road G, above Pond 005 was severely eroded for a distance of
approximately 500 feet, with riprap washed out and downcutting up
to 5 or 6 feet deep above the culvert outlet, and 10 to 12 feet
deep below the culvert. Regrading and riprap replacement will be
required along the entire eroded ditch segment. The DMG lead
specialist should be contacted to determine whether a revision
addressing design modifications will be required.
