2.05.4 RECLAMATION PLAN <br /> MCM has consolidated the permit information for all of its existing and proposed facilities,operations,and reclamation <br /> activities. Of the three underground mines;much of No. 5 Mine has been mined out,and the No. 5 Mine Portals have <br /> been sealed and reclaimed;the No. 5A/6 Mine portals have permanent seals in place and backfilling of thee portal area <br /> is proceeding;and the No.9 Mine workings are mined out and the No.9 Mine portals have been sealed and the associated <br /> facilities reclaimed. The mine access,operations,and status are detailed in Section 2.05.3 Operations Plan-Permit Area. <br /> Final reclamation plans for the Williams Fork Strip Pit are included in Exhibit 24,Williams Fork Strip Pit Reclamation <br /> Plans. Backfilling,grading, soil replacement, and revegetation seeding of the Williams Fork Strip Pit area have been <br /> completed. The Utah Tract was previously reclaimed by Utah International, as part of the Trapper Mine operations. <br /> MCM will apply for phased bond release for these reclaimed areas. Reclamation of the Town Loadout has also been <br /> completed,and final bond release has been obtained. <br /> Reclamation Plan -Methodology and Major Steps <br /> The following is a discussion of the general sequence of events,followed during reclamation of various mine disturbance <br /> areas. Site-specific plans for each major area are detailed later in this section. The major reclamation steps are as <br /> follows: <br /> • Removal of structures and facilities <br /> • Sealing of underground openings and covering of coal seams <br /> • Sealing of monitoring wells <br /> • Backfilling and grading <br /> • Redistribution of soil materials <br /> • Revegetation to appropriate land use(s) <br /> Removal of Structures and Facilities <br /> The first major step in the reclamation plan is removal of all structures and facilities. For each portal area, as well as <br /> the coal handling and storage facility,all fans,electrical substations,conveyors,and all other structures associated with <br /> the mining operation will be dismantled and removed from the mine site. In general,scrap steel and other materials will <br /> be removed from the site,but concrete demolition debris will be placed either in the abandoned underground openings <br /> prior to sealing of the portals or in excavated portal areas prior to backfilling. Mining equipment may be left <br /> underground if conditions warrant. Hydraulic fluids and oils will be removed from the equipment prior to leaving it <br /> underground. When operations ceased in 1995 and the Mine was put in Temporary Cessation status, the longwall <br /> system that was operating in the No. 6 Mine had reached the end of its useful life, so all fluids were drained from the <br /> equipment to drums or totes and removed from the Mine for disposal, and the longwall equipment was left in place <br /> when the Mine was temporarily sealed to prevent unauthorized access. <br /> Given that the Williams Fork Mines have been inactive for a period of several years, MCM periodically evaluates all <br /> existing facilities and structures,and has removed and reclaimed any structures and areas which are not critical to support <br /> potential future operations. To date, MCM has removed and reclaimed or is proceeding with reclamation of the <br /> associated disturbance areas for the following structures and facilities; Old Mine Office Building,Women's Bathhouse, <br /> Visitor Bathhouse, and No. 5 Mine Substation— 1996-1998; Men's Bathhouse, Laboratory Trailer and Sample Shed, <br /> two Rock-Dust Tanks, Brazell-Simms Building, No. 9 Mine Warehouse, and Reclamation Storage Building, - 2008- <br /> 2009; and No. 5A/6 Portal Structures, Coal Handling System, Stacking Tube, Storage Silo,Warehouse/shop, all pump <br /> housings, substation and powerlines, Railroad Spur,Williams Fork Bridge, and Track-Scale Building—2016-Present. <br /> Those structures and facilities which remain are generally structurally sound, and would have value relative to either <br /> potential future mining operations or alternative postmining land uses,if all or portions of the property were converted <br /> to another use at some future time. <br /> Facilities projected to remain in-place following permanent cessation of all mining operation and site reclamation to <br /> support the planned postmining land use include the main haulroad leading from State Highway 13 to the No. 5 portal; <br /> MT8 2.05-23 02/28/22 <br />
