2.05.4 RECLAMATION PLAN MCM has consolidated the permit information for all of its existing and proposed facilities, operations, and reclamation activities. Of the three underground mines; much of No. 5 Mine has been mined out, and the No. 5 Mine Portals have been sealed and reclaimed; the No. 5A/6 Mine portals are barricaded to prevent unauthorized access, and the associated E and F Seam workings are accessible but inactive; and the No. 9 Mine workings are mined out and the No. 9 Mine portals have been sealed and the associated facilities reclaimed. The mine access, operations, and status are detailed in Section 2.05.3 Operations Plan- Permit Area. Final reclamation plans for the Williams Fork Strip Pit are included in Exhibit 24, Williams Fork Strip Pit Reclamation Plans. Backfilling, grading, soil replacement, and revegetation seeding of the Williams Fork Strip Pit area have been completed. The Utah Tract was previously reclaimed by Utah International, as part of the Trapper Mine operations. MCM will apply for phased bond release for these reclaimed areas. Reclamation of the Town Loadout has also been completed, and final bond release has been obtained. Reclamation Plan - Methodology and Major Steps The following is a discussion of the general sequence of events, followed during reclamation of various mine disturbance areas. Site - specific plans for each major area are detailed later in this section. The major reclamation steps are as follows: • Removal of structures and facilities • Sealing of underground openings and covering of coal seams • Sealing of monitoring wells • Backfilling and grading • Redistribution of soil materials • Revegetation to appropriate land use(s) Removal of Structures and Facilities The first major step in the reclamation plan is removal of all structures and facilities. For each portal area, as well as the coal handling and storage facility, all fans, electrical substations, conveyors, and all other structures associated with the mining operation will be dismantled and removed from the mine site. In general, scrap steel and other materials will be removed from the site, but concrete demolition debris will be placed either in the abandoned underground openings prior to sealing of the portals or in excavated portal areas prior to backfilling. Mining equipment may be left underground if conditions warrant. Hydraulic fluids and oils will be removed from the equipment prior to leaving it underground. When operations ceased in 1995 and the Mine was put in Temporary Cessation status, the longwall system that was operating in the No. 6 Mine had reached the end of its useful life, so all fluids were drained from the equipment to drums or totes and removed from the Mine for disposal, and the longwall equipment was left in place when the Mine was temporarily sealed to prevent unauthorized access. Given that the Williams Fork Mines have been inactive for a period of several years, MCM periodically evaluates all existing facilities and structures, and has removed and reclaimed any structures and areas which are not critical to support potential future operations. To date, MCM has removed and reclaimed the associated disturbance areas for the following structures and facilities; Old Mine Office Building, Women's Bathhouse, Visitor Bathhouse, and No. 5 Mine Substation — 1996 -1998; Men's Bathhouse, Laboratory Trailer and Sample Shed, two Rock -Dust Tanks, Brazell -Simms Building, No. 9 Mine Warehouse, and Reclamation Storage Building, - 2008 -2009. Those structures and facilities which remain are generally structurally sound, and would have value relative to either potential future mining operations or alternative postmining land uses, if all or portions of the property were converted to another use at some future time. Facilities projected to remain in -place following permanent cessation of all mining operation and site reclamation to support the planned postmining land use include the main haulroad leading from State Highway 13 to the No. 5 portal; TR14 -36 2.05 -23 03/10/14
