construction characteristics of the disposal area are included in the exhibit. However, since the original design and <br />construction of this site was completed, the No. 9 mine site disposal area was permitted and is being used as [he <br />primary disposal site. <br />Historically, EC produces an estimated 20,000 cubic yards of waste material per 1,000,000 tons of coal mined. The <br />original waste disposal area and the new No. 9 Mine site will have capacities of 1,000,000 cubic yards and 200,000 <br />cubic yards respectively for refuse. Approximately 60,000 cubic yards of material from the H seam ramps may be <br />placed in [he waste disposal area. The combined capacities represent the refuse from the production of 60,000,000 <br />tons of coal. This capacity will be sufficient for the next 15 to 20 years of mining. Presently, the No. 9 Mine site is <br />almost completed and future refuse will be placed here prior to using the original waste disposal area. <br />SA Fresh Water Svstem <br />The No. SA fresh water system is no longer in use. Currently, fresh water is supplied from underground sumps in <br />the No. 5 Mine. Two (2) underground pumping stations are used to maintain pressure and flow throughout the <br />mine. <br />To maintain a more reliable pumping system, especially in the event of an underground emergency, EC is planning <br />to change to a system with surface pumps and storage. The water source will be the No. 5 Mine dewatering ponds. <br />Pressure pumps will be placed at the ponds. Water will be pumped into the No. 5 and No. 6 mines via a pipeline <br />that enters the mines through a converted power borehole near the silo. <br />Railroad Snur <br />The railroad spur was constructed in 1978 from the DR & WR Railroad to enable unit trains to load coal from the coal <br />silo at the facilities area. <br />Red Rock Crusher Site <br />The red rock crusher site is located just to the east of the SA portals. The crusher site was used to crush rock from the <br />red rock quarry for use on underground haulage roads and surface access roads. Previously the crusher facility <br />consists of a constructed pad, truck ramp, hopper, gyratory crusher, and screens for sizing crushed rock. Presently, <br />only the storage pad and road into the site exists. <br />Rock Dust Tanks <br />There are four rock dust tanks currently in use at EC. These are: <br />EC Village <br />Shop <br />No. SA <br />These tanks are required [o store dust for dusting purposes of the mined out underground areas. <br />Maeazine <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 />Permit Revision 04-34 2.05-15 Revised 7/2/04 <br />
