• Rock Dust Tanks <br />There are four rock dust tanks currently in use at RAG Empire. These are: <br />RAG Empire Village <br />Shop <br />No. SA <br />These tanks are required [o store dust for dusting purposes ofthe mined out underground areas. <br />Magazine <br />The magazine location is shown on Map 25, and Map 26, and as can be seen, it is located in the general area of the <br />No. 5 Portal. <br />Two magazines will be used to store permissible powder and blasting caps. One magazine is approximately 2.5' x 2.3' <br />x 2.5', while the other is approximately 5' x 6' x 7'. <br />The old magazine located north of the red rock crusher site (for which a small area exemption exists) of <br />approximately 100 feet square was reclaimed. Approximately 185 cy of topsoil was spread to a depth of about 6 <br />inches. The site was then seeded. <br />Ancillary Facilities <br />. Ancilliary facilities include railroad track scale, miscellaneous light duty roads, and miscellaneous storage yards. <br />These facilities are shown on the Structures and Renewable Resources Map (Map 25). <br />Construction drawings of many of the facilities listed above were included in previous RAG EC permit submittals <br />(1983). Since these facilities are now in place and have been approved by the appropriate Government agencies, these <br />drawings have been deleted from this submittal. <br />Mul[iole Services Building <br />Empire constructed a multiple services building [hat is approximately 6,250 ft2, and a 100,000 gallon water storage <br />tank. The location for the building and water tank is shown on Maps 25 and 26. <br />The building houses bulk storage tanks (as identified on page 2.05.3R), emulsion pumps, water pumps, air <br />compressors, a waste oil furnace, an oil water separator, and two open areas for equipment maintenance and storage <br />of [he fire [rnck/foam generating equipment. The power supply for the building comes from [he existing substation, <br />located in the SA storage yard. Apad-mounted transformer is located adjacent to the building. The water tank is used <br />in conjunction with the water pumps to provide high-pressure water to the underground mine water system. <br />Boreholes are used to drop the water lines into the mine. This water is used to supply water for the emulsion system, <br />for dust control and, in an emergency, for fire fighting. The emulsion pumps pump mixed emulsion underground to <br />the longwall. Boreholes are used to provide compressed air from air compressors for use underground. As shown on <br />Map 25, the building is constructed within the SA portal area and the water tank on the road to the red rock crusher <br />site. As a result, there was no new disturbance from this construction. Reclamation for these sites is discussed under <br />• [he SA portal and red rock crusher. Bond calculations for the building and tank removal are shown in Exhibit 25. The <br />only additional sediment control is a slight expansion of the red rock crusher small area exemption and the relocation <br />of ditch CS-D2, as shown on Map 26. <br />APPRO~D M!~R 15 if~2 <br />MidTerm Response 2.05-16 ~\"~o~~ Revised 12/05/01 <br />
