Mine Storage Yard. A pad - mounted transformer is located adjacent to the building. The Multi- Services Building is <br />constructed within the 5A Portal Area, and the water tank is on the road to the Red Rock Crusher site. As a result, <br />construction resulted in no new disturbance, and the only additional sediment control required was expansion of the <br />Red Rock Crusher SAE and relocation of Ditch CS -D2, as shown on Map 26. Reclamation for these sites is discussed <br />under the 5A Portal and Red Rock Crusher. Bond calculations for the building and tank removal are included in <br />Exhibit 25. <br />In order to provide access at the rear of the Multi- Services Building, approximately 2,000 cy of material was removed <br />from a previously disturbed area, and the removal of this material resulted in only a slight increase in the slope angle. <br />The material removed was placed in the existing rock storage area, as shown on Map 26 and discussed in Vol. 10, <br />Exhibit 40. The rock storage site is permitted for 12,000 cy, and with placement of this material, has a remaining <br />capacity of 4,600 cy. The volume removed is less than 1 percent of the total volume of overburden to be moved <br />during final reclamation (290,000 cy), and is not being removed from 5A area, so it was not necessary to adjust final <br />contours. <br />During 2011 -2012, given the ongoing inactive status of the property, MCM completed testing and removal of <br />petroleum products, emulsion fluids, and other chemicals and chemical wastes from the Multi- Services Building, <br />and exterior storage tanks, and completed EPA compliant closure of the tanks, using a licensed waste contractor. <br />The water tank is used in conjunction with the water pumps to provide high- pressure water to the underground mine <br />water system. Boreholes are used to drop the water lines into the mine to supply water for the emulsion system, for <br />dust control and, in an emergency, for fire - fighting. The emulsion pumps in the Multi- Services Building pump can be <br />used to mix emulsion and transfer it underground to the longwall. The boreholes are also used to route compressed air <br />lines from the air compressors underground. <br />Miscellaneous Shop, Storage and Utility Buildings — Several miscellaneous shop, storage, and utility buildings were <br />constructed and utilized to support ongoing mining operations including a Carpenter Shop, the Brazell -Simms <br />Building, the No. 9 Mine Warehouse, and the Reclamation Building (Pole Barn). All of these miscellaneous buildings <br />have been removed and the associated disturbance areas reclaimed. <br />Oil and Chemical Storage - The following petroleum product tanks are located on the Williams Fork mine -site. MCM <br />completed a program to remove all petroleum products, other liquid products and waste fluids from the site in late - <br />2011 and early 2012. The identified tanks remain on -site, however, in 2011 -2012 the tanks were emptied, the <br />products were removed from the site, and MCM completed EPA compliant closure of all tanks using a licensed waste <br />contractor. <br />No. 5 Mine Portal Area (Main Fueling Station and Shop) <br />SUBSTANCE <br />MAXIMUM QUANTITY <br />CONTAINMENT <br />AREA <br />Antifreeze <br />500 gallons <br />concrete basin <br />Fuel island <br />Diesel fuel <br />8,000 gallons <br />concrete basin <br />Fuel island <br />Oil <br />2,000 gallons <br />concrete basin <br />Fuel island <br />Gasoline <br />1,000 gallons <br />concrete basin <br />Fuel island <br />Oil <br />1,375 gallons <br />concrete floor /curbs <br />Shop pump room <br />Antifreeze <br />275 gallons <br />concrete floor /curbs <br />Shop pump room <br />Used oil <br />500 gallons <br />concrete basin <br />SE of shop <br />No. 5A/6 Mine Portal Yard Area (Fueling Station) <br />SUBSTANCE <br />MAIIIMUM QUANTITY <br />CONTAINMENT <br />AREA <br />Antifreeze <br />360 gallons <br />concrete basin <br />5A yard <br />Diesel fuel <br />4,000 gallons <br />concrete basin <br />5A yard <br />Oil <br />2,000 gallons <br />concrete basin <br />5A yard <br />TR14 -36 2.05 -8 Revised 09/08/14 <br />
