Colowyo C-1981-019
18 May 10
Pg 6/7
General Mine Plan Compliance (cont.): - The 115 excavator operation was removing
131-Seam overburden in the South Taylor box-cut area. As stated above, the
overburden material is being hauled to the final cut of the Section 16 Pit.
Revegetation/Reclamation Success: - The 2009 East and West Pit reclamation areas
are both stable and in overall good condition, as stated above in "Backfilling and
Grading". The vegetation in these areas is just starting to germinate. The new growth
appears to be very uniform, with no large bare spots seen. These areas will continue
to be monitored over the summer.
Slides and Damage: - As briefly stated above, the large gully area in the 2007 2008
East Pit reclamation (that has been noted in several previous inspection reports) has
created a problem for the upper area of the 2009 East Pit reclamation, with fairly
extensive rilling in the area. This gully area will need to be repaired early this summer.
Colowyo will need to come up with a detailed plan for the repair and monitoring of
this area. The repairs will likely require Colowyo to first strip off the topsoil, then
repair/regrade the area, replace the topsoil and reseed the area.
Slides and Damage (cont.): - In the 2010 Midterm Review (question #22, dated 10
May 2010) the Division has requested that Colowyo submit a rill and gully plan. This
plan is required no later than 25 June 2010. The question from the 2010 Midterm
reads as follows:
Currently, Colowyo does not have a rill and gully plan in their permit, as
required by Rule 4. 14.6. Given the fact that there are several areas at the
Colowyo Mine that have extensive gullying that has not healed itself or been
fixed by the operator, the Division requests that Colowyo include a detailed rill
and gully survey and remediation plan in their permit. The plan should include,
at a minimum:
a. A plan to perform (at least yearly) rill and gully monitoring and
reporting, with reporting to be completed each spring and a final
report submitted to the Division no later than 15 June of the
monitoring year.
b. A map or plate showing the rill and gully area(s) in detail.
c. A plan for remediation of the rill and gully areas) including a
timeframe for the remediation work(which must be completed in the
some calendar year as the monitoring and reporting).
d. A Description of the topsoil salvage and replacement activities for the
rill and gully remediation area(s).
e. A plan for reseeding the rill and gully remediation area(s).
f. A plan for continued monitoring and reporting of the rill and gully
remediation areas) in future years. This plan should include a
minimum timeframe for continued monitoring to ensure successful
remediation.
