RE: Twentymile Coal Company - Foidel Creek Mine (Permit No. C-82-056), Minor Revision (MR08-233)
for Refuse Pile Clay Staging Area
Dear Ms. Binns:
Twentymile Coal Company (TCC) requests CDRMS approval of a Minor Revision to our approved Mining and
Reclamation Permit to utilize an existing ranch road for haulage of clay materials, establish a temporary clay stockpile
on an existing permanent excess overburden stockpile, and establish and maintain associated temporary support and
drainage structures.. The proposed clay handling activities are necessary to preserve suitable clay materials for use as
the final cover material for the existing Coal Refuse Disposal Area, and to facilitate placement of refuse in the
remaining available area for the existing permitted Refuse Pile.
Approximately 70,000 cubic yards of suitable clay material will be recovered from the remaining refuse placement
area and hauled to and placed in the temporary stockpile area. It is anticipated that the clay material will be stockpiled
for less than a year, with placement of the clay as cover material on the western slope of the Refuse Pile as soon as
ongoing refuse placement and grading bring this area to the final design elevation and grade. Prior to disturbance,
available soil materials will be recovered from the haulage route and stockpile footprint, and stockpiled on the surface
of the permanent excess overburden stockpile. Due to the very temporary nature of the planned stockpile, drainage
from both the clay and soil stockpile areas will be controlled using Alternative Sediment Control methods including
berms and wattles. Temporary support structures will be limited to an equipment fueling site with a portable fuel tank
and lined secondary containment adjacent to the haulage route on the stockpile margins.
This submittal includes revised PAP text and maps/drawings addressing the location and configuration of the
proposed clay handling and staging area. New and revised PAP materials are identified by the enclosed Summary of
Revisions/Additions. TCC would like to proceed with this project as soon as possible, so that clay recovery and
stockpiling can be completed before winter conditions make operations too difficult. Therefore, we appreciate your
consideration and cooperation in facilitating timely review and approval. Once you have had opportunity to review
the accompanying information, please feel free to contact me with any questions or to discuss related matters.
Best regards,
for Twentymile Coal Company
