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 focis of evidence supporting the enforcement action.
Carry-over items of concern from previous inspections: A revision is required to the Permit
Application Package to post personnel changes at Colowyo Coal Company, L.P. (inspection
report of 12 Sep Ol). The new field office building needs to be included on Drawings 22 and 38
(inspection report of 12 Sep Ol ).
These two items have not been resolved as of the date of this report. A summary of items of
concern or of interest developed as a result of this inspection include:
1) The appearance of damage to the permanent perimeter ditch in the vicinity of E1359000
N347100 (north side of East Pit reclamation, west of Streeter Fill).
2) Corrections to Drawing 12, revised 5/30/01, appear to be warranted. What appears to be a
collection ditch in Photograph 8, from the Gulch A ravine towards the north and tying into the
ditch feeding into the Streeter drainage collection system, does not appear on the Drawing. If
appropriate, please add this ditch, labeled, to Drawing 12. In addition, please label, on
Drawing 12, the 3300-foot ditch towards the Streeter drainage collection system, and the main
relief drain (7900-foot ditch) off the Gulch A water shed to the Gulch A pond.
