Subject: RE: Perimeter Disturbance Markers Policy
Dear Scott and Kathy -
I'm forwarding an e-mail from Sandy Brown regarding resolution with OSM of issues pertaining
to perimeter markers at underground mines raised during last year's Oversight Evaluation
Year.
Kathy - We will now proceed with finalizing our review of MR-366 to the West Elk Mine permit
in accordance with Sandy's e-mail. As you can see, perimeter markers will now be required at
underground coal mines to mark the perimeter of only those areas associated with long-term
operations or facilities. Perimeter markers will need to be erected at long-term
operations/facilities before surface disturbances associated with those operations/facilities
begin, and will need to be maintained until those surface disturbances are granted Phase III
bond release. Perimeter markers will not be required to demarcate approved surface
disturbance boundaries associated with methane drainage wells; however, Mountain Coal
Company's current practice of utilizing 6" X 12" signs to denote locations of MOW sites for
the benefit of DRMS inspectors, MCC personnel, and the public is exemplary, so we will
suggest in our review of MR-366 that MCC continue this practice.
Scott - Current language in the Deserado Mine permit at Section IV.K "Signs and Markers"
states that markers were placed around Deserado's permit boundary, and further states that
boundaries of long-term disturbances are to remain marked until such time as the extent of
the disturbance is complete. Blue Mountain Energy should now submit a Minor Revision to the
Deserado Mine permit to (1) remove references in the permit to markers being placed around
the mine's permit boundary, and (2) revise existing language so as to state something along
the lines of "the perimeter of areas to be affected by long-term operations or facilities
will be clearly marked before the beginning of surface coal mining operations and will remain
