The plans for the No. 6 Mine have been included in this permit as Exhibit 16, MSHA Roof and Ventilation Plans.
<br />When approved, the plan for the No. 6 Mine will be included in this exhibit.
<br />Mine Facilities
<br />The surface facilities associated with the No. 5, No. 5A, and No. 6 mines are shown on the Structures and Renewable
<br />Resources Map (Map 25). Listed on Table 56, Mine Structures and Facilities, are the major structures currently
<br />existing (or reclaimed) at the Williams Fork Mines. The Table provides approximate construction dates of the
<br />facilities, as well as the dates of last modification or removal. All or most of the existing facilities, including ancillary
<br />facilities used at the No. 5 Mine, were used for the No. 6 Mine, and would be used for any future mining. A new
<br />Multi- Service Building and 100,000 gallon water tank were constructed during 1989, as shown on Maps 25 & 26.
<br />The Multi- Service Building houses storage tanks and distribution piping and equipment for mining fluids and
<br />lubricants. In 2011, all fluids were drained, and the tanks were plugged and capped, consistent with EPA
<br />requirements for tank closure.
<br />No. 5 Mine
<br />No. 5 Mine Portals - The 5 Mine Portals were constructed in 1970 to access the "F coal seam". The portals consisted
<br />of four entries and associated portal structures at the "F seam" outcrop. The portals were primarily used for
<br />ventilation supply and personnel transport. These portals were sealed, backfilled, and reclaimed in 2002.
<br />No. 5A and 6 Mine Facilities
<br />No. 5A Mine Portals - The 5A Mine Portals and associated facilities were established in and adjacent to the highwall
<br />of an abandoned strip pit. The 5A Mine Portals consist of four portal entries, one for intake air, two for return air, and
<br />the fourth for the mine conveyor. Main ventilation fans for the No. 5 and 6 Mines are installed on the two return air
<br />portals. One new opening to the surface (a short, angled intake air shaft) is planned to improve airflows. A shaft,
<br />located above the existing 5A portals and within the existing sediment control system, was planned from the surface to
<br />the No. 5 and No. 6 mines (Note: The shaft would be reclaimed along with the No. 5A portals). For location of the
<br />ventilation fans, refer to the No. 5 Mine Plan Map (Map 23). Oil storage tanks, a rock dust tank, a supply yard, and a
<br />sediment pond are located in the 5A portal area. Drainage and sediment controls for the 5A Portal area are discussed
<br />later in this section.
<br />General Mine Facilities
<br />Main Office, General Manager's Office, Engineering Offices, and Training/Maintenance Office - The Mine offices
<br />were originally located near the employee housing are on the east side of State Highway 13. Offices were
<br />subsequently relocated near the No. 5 Portal. The offices consisted of mobile trailers and housed the Mine Manager,
<br />safety and training personnel, engineering staff, and other mine personnel. By the end of 1999, all of the office trailers
<br />had been removed from the property, and the environmental/engineering offices were relocated to the upper floor of
<br />the warehouse.
<br />Shop/Warehouse - A new shop was constructed in 1981 to replace the old shop, located near the now abandoned
<br />employee housing area. The Shop is located just west of the rail spur, and provides an enclosed, heated facility for
<br />maintenance of underground and surface mining and support equipment.—The CMLRD approved construction of the
<br />Warehouse and Storage Yard in September 1983. The approval allowed for construction of a building 60 x 100 feet,
<br />with a loading dock. The Warehouse was constructed adjacent to, and connected with, the shop on a previously
<br />disturbed area. The Warehouse is used for storage and distribution of parts and supplies to support active mining and
<br />related operations.
<br />Multi- Services Building - A Multi- Services Building, of approximately 6,250 square feet, and a 100,000 gallon water
<br />storage tank were established at the No. 5A Mine Portal Area to support active mining operations, as shown on Maps
<br />25 and 26. The building houses bulk storage tanks, emulsion pumps, water pumps, air compressors, a used -oil
<br />furnace, an oil/water separator, and two open areas for equipment maintenance and storage of the fire truck/foam
<br />generating equipment. The power supply for the building comes from the existing substation, located in the No. 5A
