Hernandez, Daniel <br />From: Hernandez, Daniel <br />Sent: Thursday, October 14, 2010 2:33 PM <br />To: 'Scott Wanstedt'; 'Welt, Kathy' <br />Cc: Brown, Sandy; Berry, David; Kaldenbach, Tom; Binns, Janet <br />Subject: RE: Perimeter Disturbance Markers Policy <br />Dear Scott and Kathy - <br />I'm forwarding an e-mail from Sandy Brown regarding resolution with OSM of issues pertaining to perimeter markers at <br />underground mines raised during last year's Oversight Evaluation Year. <br />Kathy - We will now proceed with finalizing our review of MR-366 to the West Elk Mine permit in accordance with <br />Sandy's e-mail. As you can see, perimeter markers will now be required at underground coal mines to mark the <br />perimeter of only those areas associated with long-term operations or facilities. Perimeter markers will need to be <br />erected at long-term operations/facilities before surface disturbances associated with those operations/facilities begin, <br />and will need to be maintained until those surface disturbances are granted Phase III bond release. Perimeter markers <br />will not be required to demarcate approved surface disturbance boundaries associated with methane drainage wells; <br />however, Mountain Coal Company's current practice of utilizing 6" X 12" signs to denote locations of MDW sites for the <br />benefit of DRMS inspectors, MCC personnel, and the public is exemplary, so we will suggest in our review of MR-366 <br />that MCC continue this practice. <br />Scott - Current language in the Deserado Mine permit at Section IV.K "Signs and Markers" states that markers were <br />placed around Deserado's permit boundary, and further states that boundaries of long-term disturbances are to remain <br />marked until such time as the extent of the disturbance is complete. Blue Mountain Energy should now submit a Minor <br />Revision to the Deserado Mine permit to (1) remove references in the permit to markers being placed around the mine's <br />permit boundary, and (2) revise existing language so as to state something along the lines of "the perimeter of areas to <br />be affected by long-term operations or facilities will be clearly marked before the beginning of surface coal mining <br />operations and will remain marked during the conduct of all activities to which they pertain until final bond release. <br />Perimeters markers will not be required to demarcate approved surface disturbance boundaries associated with short- <br />term operations/facilities such as methane drainage wells, though the approved boundaries of these short-term <br />disturbances may be temporarily marked with survey stakes, laths or flags." Please note that this proposed language is <br />simply a suggestion, but a suggestion that I believe addresses both OSM's and Blue Mountain's concerns. <br />Thank you both for your input, and for your patience. Please feel free to call me with any further questions or <br />comments you may have. <br />Dan <br />Danie(L Hernandez <br />Daniel I.
