7anet Binns and Dan Hernandez made introductions of inspection participants, and
briefed the group regarding the bond release application, inspection objectives, specific
acreages to be evaluated, and inspection plan to inspect all the surface acreage proposed
for release. BT'(7 &DMG representatives provided geologic x-sections, affected area and
surface land ownership maps, other maps of the proposed release acreage, and briefed the
group using these maps.
DMG began the bond release inspection by walking and inspecting the railroad line and
ROW through the permit and affected area (the Colowyo Mine representative
participated in this.inspeetion primarily because ICenneeon Energy owns and controls the
railroad spur through the Eagle Mines permit area). We made general observations, and I
took photographs (I took 4 rolls, total for both days, of 35mm prints which I will provide
to DMG).'(~e did not idenri.fy any surface subsidence features on or along the railroad
line or RO'aJ.
From the southern end of our inspection walk, along where the railroad line leaves the
permit area, we made stops and observations at the following: (I took photos at all stops
and potential subsidence features. On Nov. 18, Rocky Thompson and Brad Barker took
GPS coordinates of features, and on Nov. 19 Mr. Barker and I took GPS coordinates of
features. During the inspection 1 discussed with Mr. Barker OSM's oversight role,
various definitions including afected area, and surface coal mining and reclamation
operations; and mitigation, or. recommending no mitigation, for surface effects of
subsidence.)
Last of the railroad line we inspected what appeared to be one area where subsidence
effects were graded and repaired, a west :facing slope in sagebrush; and another azea
closest to the railroad Iine where it also appears grading has occurred in the past to
stabilize a ]and movemen[ or slump. Thet~e is sparse vegetative cover and some erosion
on bare soil areas adjacent to the railroad, and on south facing slopes around this area.
I did not walk the entire area closest to the railroad. The repaired west 'Facing slope area
in the sagebrush is well vegetated and appeared stable.
We inspected several small sinkholes-animal burrows /one sandstone outcrop crack /and
"several small parallel troughs" typical of surface subsidence, just north of the former air
iraonitoring tower location. These features were parallel to each other in places, and
singular in others. first stop /sinkhole north of the tower is at N 40 26 02 W 107 39 10
at 6,330 'Ft.; and short troughs and sinlcltoles appear at two hundred to five hundred feet
nanh and west of this fast step.
