Introduction In their Mid-Term Permit Review comments, dated November 2005, the CDRMS requested clarification of the status of the Loadout facilities area between what is existing and on-the-ground and what is approved via Technical Revision No. 6 (TR-06). The existing and on-the-ground structures were constructed during the time period 1879 through 1980 by the previous owner/operator/permittee, H-G Coal Company. HGTI proposed a significant modification to the Facility as part of TR-06. This modification will convert the facility from a truck load-in/rail car out operation, with an originally permitted through-put of 1,000,000 tons per year to a rail car in/truck load out operation, with a permitted through- put of 2,000,000 tons per year. The CDRMS approved TR-06 in June 2005. Most of the existing support features (i.e., sedimentation ponds, drainage ditches, road s) will be retained as constructed upon completion of the TR-06 approved modi fications. The major changes will be the demolition and, or relocation of several coal handling Structures. Exhibit 12-1, Facilities Map (Revision 14, dated 03/07) and Exhibit 12-2, Surface Water Control Plan Map (Revision 11, dated 03/07) show how the facilities area will be configured following the completion of the TR-06 approved modifications. This attachment describes the coal handling facilities area in its current, on-the-ground condition. Several maps which have been superseded by approved permit revisions are included in this attachment and show the current, on- the-ground condition. These maps are: • Exhibit 12-1, Facilities Map (Revision 9 TR-04 Incidental Permit Boundary Change, dated 6/99) • Exhibit 12-2, Surface Water Control Plan Map (Revision 5, TA-09 Incidental Permit Boundary Change, dated 8/99) References to the maps in this attachment generally will be to the superseded material noted above. The format for this attachment is similar as that presented in Tab 12. Similar major section headings (e.g., Sediment and Water Control Facilities Plan) are used. A third map is also included in this attachment. This map is Exhibit 12-5, Haul Road HGLF-HR2 (Revision 0, dated 2/3/93) which shows a proposed haul MR-15 1 Revised 03/07
