III. Emissions Permits 1. Final approval was requested for Emissions Permits in 1984, and was received in May and June, 1989. Initial approvals were retained on two permits, one for the upper refuse pile and one for a coal fired boiler, which have not yet been constructed. Copies of all the permits were submitted to the Division at that time. Additional copies are attached and should replace those in Volume 4. IV. Future Increases in Coal Production 1. MCC submitted Technical Revision #57 in September, 1990, to increase West Elk Mine's projected production tonnage to that more typical of a longwall. The Division approved TR #57 on December 4, 1990. V. Topsoil 1-3. MCC has entered into a contract with Greystone Consultants, Inc. to update and restructure West Elk Mine's (WEM) permit. Part of this work includes revising WEM's Surface Facilities map and having it scanned into an AutoCAD computer program. The base computer map can then be updated & changed adding the soils information, drainage information, and any other changes that have been requested in the renewal adequacy questions or will be added by future revisions. The restructured permit with the new maps will be completed by October 31, 1991. VI. Surface Hydrology 1-2. As mentioned above, a new drainage map is to be prepared using the base Surface Facilities map on WEM's AutoCAD program. In addition, all ditches and culverts will be listed and designs summarized. This will be included in the restructured permit to be completed by October 31, 1991. 3. Per the Division's recommendations during several site inspections, including those completed in August, 1986, and May, 1987, MCC does not plan to remove any slide debris from the upper diversion ditch. We concur that much greater disturbance would be caused by the removal of the landslide
