The plans for the No. 6 Mine have been included in this pen-nit 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, removal, or scheduled removal. All or most of the existing
<br /> facilities, including ancillary facilities used at the No. 5 Mine, were used for the No. 6 Mine. A new Multi-Service
<br /> Building and 100,000 gallon water tank were constructed during 1989, as shown on Maps 25 & 26. The Multi-
<br /> Service Building houses storage tanks and distribution piping and equipment for mining fluids and lubricants. In
<br /> 2011, all fluids were drained, and the tanks were plugged and capped, consistent with EPA requirements for tank
<br /> closure. With a decision to not pursue future mining plans, final reclamation of mine facilities was initiated in 2016.
<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. Portal sealing and reclamation are scheduled for 2018—2020.
<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. The Shop/Warehouse will be dismantled and removed from the site for re-use in 2018.
<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
