This was a partial inspection of the Colowyo Mine conducted by Jim Stark of CDRMS.
The inspection was conducted on 18 June 2009. Andy Thompson of C-CC
accompanied me in the morning and Tay Tonozzi accompanied me in the
afternoon, The mine was actively mining coal and hauling coal to the loadout at the
time of the inspection. The weather was warm and overcast and it was raining on
and off during the inspection. The ground was wet and muddy in spots due to the
rain.
Roads: - The main access road and haul road to the Gossard Loadouit is a paved
road. The road was wet at times (due to the rain) and in good condition,
- The light-use road in the Taylor Draw was inaccessible due to the rain,
- The haul roads in the East Pit, West Pit were all stable and well maintained at the
time of the inspection. There was not a problem with fugitive dust from the roads due
to the rain and no erosional problems were noted.
- The haul roads in the South Taylor Pit were all mostly dry and there was not a
problem with fugitive dust at the time of the inspection. Colowyo is currently working
on a new road on the west edge of the West Pit into the South Taylor Pit, which will
replace the road through the old Section 16 Pit. The Division just received the
Colowyo responses to the Technical Revision 76 PAR letter and is currently reviewing
them.
- The Sturgeon road was well maintained and stable and there were no erosional
problems noted. The Missouri crossings along the road remain in good condition.
The road surfacing has held up well and all of the roadside ditches were clean and
functioning properly.
Hydrologic Balance: - The Wash Bay Pond (not a NPDES discharge point) was not
inspected.
- The Work Area Pond (NPDES 002A) contained water approximately 'l-1/2 feet below
the top of the discharge pipe (just below the weep hole) and was not discharging at
the time of the inspection. The embankment was well vegetated and stable and no
erosional problems were noted. The emergency spillway appeared to be stable.
