Attached is an updated map showing where mining <br />has occurred in the B-seam. Please note that your building, currently under construction at the <br />head of Lone Pine Gulch, appears to overlie the 5th or 6th Northwest longwall panels (the 5th <br />and 6th longwall panels from the right on the map), but needs to be confirmed by survey. MCC <br />currently projects that retreat (longwall) mining of the 5th Northwest panel in this area b}' the end <br />of November, 1994. <br />Although h4CC does not believe that subsidence (or lowering of the ground surface) will affect <br />the building, MCC would like to conduct apre-mining survey of the building. This survey will <br />include mapping of the exact topographical Location, elevations of various points on and near the <br />building and an evaluation of current condition of the building. In this way MCC can ensure that <br />impacts to the building from mining, if any, can be identified. We would like to conduct this <br />survey at least once before the end of October and then again after mining has passed under the <br />area. As MCC does not know what your completion and occupancy schedules are for the <br />building, please let me know what dates would be open for the surveys during October through <br />December. Additional surveys may be scheduled next year, as necessar}~. <br />Please feel free to call me or Phil Schmidt with dates that surveys could be scheduled or should <br />you have questions. <br />Sincerely, <br />~~~~ <br />- Kathleen G. Welt, <br />Environmental Supervisor <br />Attachments <br />
