MT8 2.05-23 02/28/22 <br />2.05.4 RECLAMATION PLAN <br /> <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 /> <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 /> <br />Reclamation Plan - Methodology and Major Steps <br /> <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 /> <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 /> <br />Removal of Structures and Facilities <br /> <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 /> <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 /> <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 /> <br />
