The old magazine located north of the red rock crusher site (for which a small area exemption exists) of approximately 100 feet square was reclaimed. Approximately 185 cy of topsoil was spread to a depth of about 6 inches. The site was then seeded. Ancillary Facilities Ancilliary facilities include railroad track scale, miscellaneous light duty roads, and miscellaneous storage yards. These facilities are shown on the Structures and Renewable Resources Map (Map 25). Construction drawings of many of the facilities listed above were included in previous EC permit submittals (1983). Since these facilities are now in place and have been approved by the appropriate Government agencies, these drawings have been deleted from this submittal. Multiple Services Building EC constructed a multiple services building that is approximately 6,250 ft2, and a 100,000 gallon water storage tank. The location for [he building and water tank is shown on Maps 25 and 26. The building houses bulk storage tanks (as identified on page 2.05.3R), emulsion pumps, water pumps, air compressors, a waste oil furnace, an oiUwater sepazator, and two open areas for equipment maintenance and storage of the fire truck/foam generating equipment. The power supply for the building comes from the existing substation, located in the SA storage yard. Apad-mounted transformer is located adjacent to the building. The water tank is used in conjunction with the water pumps to provide high-pressure water to the underground mine water system. Boreholes are used to drop the water lines into the mine. This water is used to supply water for the emulsion system, for dust control and, in an emergency, for fire fighting. The emulsion pumps pump mixed emulsion underground to the longwall. Boreholes are used to provide compressed air from air compressors for use underground. As shown on Map 25, the building is constructed within the SA portal area and the water tank on the road to the red rock crusher site. As a result, there was no new disturbance from this construction. Reclamation for these sites is discussed under the SA portal and red rock crusher. Bond calculations for the building and tank removal are shown in Exhibit 25. The only additional sediment control is a slight expansion of the red rock crusher small area exemption and the relocation of ditch CS-D2, as shown on Map 26. In order to provide 10 feet of access at the rear of the building, EC proposed to remove approximately 2,000 yd3 of material from approximately 11,200 ftZ of slope behind the building. The entire azea has previously been disturbed, and the removal of this material resuhed.in only a slight increase in mean slope from 43% to 48% (longest cut slope 75'). The material removed was placed in the existing rock storage area, shown on Map 26 and discussed in Vol. 10, Exhibit 40. The rock storage site is permitted for 12,000 yd3, and still has room for 4,600 yd3 before the 12,000 yd3 is reached. Therefore, the 2,000 yd3 from the cut will easily fit in this area. This material will be placed as discussed in Exhibit 40. This volume of material (2,000 yd3) is less than 1% of the total volume of overburden to be moved during final reclamation (290,000 yd3), and is not being removed from SA area, so final contours are not being adjusted. Livestock Ponds EC submitted Technical Revision Number 7 for the Division on September 10, 1987 detailing the plans for installing livestock ponds. This revision has been placed in Exhibit 41 of the pemut. Haulaee and Access Roads The location and classification of all roads used at EC mine site is shown on the Roads Map (Map 27). EC, in agreement with Moffat County have taken responsibility for these roads. Included in Exhibit 17, Road Certification, is correspondence, which identifies the roads, which have been vacated to EC. Permit Revision 04-34 2.05-16 Revised 7/2/04
