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.
CRDA-1 Vicini
Inspection began at CRDA-1 on the morning of Mazch 25. Topsoiling of CRDA-1 was continuing but
neazing completion. The only portion of the pile that will not be reclaimed during the current project is the
temporary pile access road that ex[ends onto the pile from [be upper end of Haul Road No. 5. Water bazs
aze to be constructed at intervals along the temporary road to divert road drainage into the perimeter ditch
upon project completion. The temporary road may be used for disposal ofcoaly material from clean-up of
various mine facility azeas during the duration of reclamation, and is scheduled to be reclaimed by the end
of 2004. Remaining work to be accomplished during the current project on CRDA-1 includes final
grading of upper terrace drains, final installation andriprapping of the upper segments of permanent
perimeter ditches, reclamation of Access Road 4 from CBA-2, seedbed prepazation/soil roughening,
placement of rock goups, and seeding/mulching Revegetation is planned to be completed by the end of
April. Any areas (other than the the temporary road) that aze not final seeded by the end of April, will be
final seeded during the fa112002 seeding window. Completion of the pile reclamation and permanent
perimeter ditch installation in accordance with all aspects of the approved design will need to be
certified by a P.E.
Vegetation sampling was conducted on the refuse slopes seeded in 1994 on Aprii 13. The sampling was
conducted by students from a Mesa State College disturbed ]and reclamation class, under the supervision of
DMG personnel. Results of the sampling exercise will be documented in a sepazate report. It was noted on
that date that extensive soil roughening and rock placement had been completed on the upper bench slopes
of CRDA-1, and that seedbed prep ripping and rock placement had been lazgely completed on the top of the
pile. The work appeazed to have been performed in accordance with permit requirements and as clarified
in the February DMG inspection report. Placement of perimeter ditch fabric undertiner and riprap was in
progress.
Ponds 6 and 10 were dry.
The Coal Creek permanent diversion was essentially as described in the February 27 inspection report.
Final construction will need to be certified by a P.E. Some rock removal and seedbed prep ripping still
needed to be completed in the Topsoil Pile 7 area, adjacent to Pond 10. Reclamation of the permanent
diversion and adjacent azeas with the exception of Sediment Ponds 6 and 10 is to be completed by the end
of April.
Topsoiling of the re-disturbed portion of CBA-1 had not yet been completed. The CBA-1 sediment trap
was dry with adequate capacity.
CRDA-2
CRDA-2 was also inspected Mazch 25. Cover soil placement andtopsoiling had been lazgely completed.
Additional channel shaping andriprap placement had been completed on the new upper diversion since the
previous inspection, but final construction had not yet been completed. The lazgeriprap energy dissipation
segments at the channel outlets had been installed, but it appeazed that some addiiionalriprap placement
