Re: Minor Revision No. 220 (Expansion of Material Storage Bench); West Elk Mine;
Permit No. C-80-007
Dear Ms. Johnston:
The Division has reviewed the Minor Revision No. 220 application and has the following
adequacy comments.
Revised Map 54 now includes revised topography at the Materials Storage Bench (MSB)
and Portal Bench Storage Area. The revised map does not include the proposed changes
to ditch D2-6C or culvert C2-3A. Please revise the map to include all proposed changes.
2. MCC, in the cover letter to MR-220, notes that the changes to the MSB configuration do
not warrant revisions to the ditch or culvert designs, but that D2-6C and C2-3A will be
altered to accommodate the bench expansion. Regardless of whether the structures would
need to be enlarged, MCC needs to revise the designs to ensure that information in the
permit application package is consistent with on-the-ground conditions. Please revise the
designs in accordance with the proposed changes.
3. One of the maps submitted by MCC is Map 58A, "Access Road Loop and Material
Storage Area Reclamation Plari'. The currently approved permit application package
includes a Map 58A which is entitled "Sylvester Gulch Reclamation Plan". It does not
seem appropriate to replace the current map, as existing information would be lost.
Please renumber and resubmit one of the maps.
4. The newly submitted Map 58A does not show any reclamation at the west end of the
MSB or the east end of the Portal Bench Storage Area. Maps 53 and 54 show cuts and
fills in these aeeas. Please revise Map 58A to indicate that these areas will also be
regraded to approximate original contour.
