<br />The coal refuse material to be disposed of during mining operations is not considered combustible,
<br />physically unstable, or acid-toxic forming. Chemical and physical,'analysis for this material is
<br />contained in Figure 6-2. Refuse separated from the raw coal mined„ will be placed in the refuse
<br />disposal areas described in Section 2.05.3(8}, Tab 13. See Section VIy below.
<br />i
<br />Non-coal wastes,' including flammable liquids, paints, gazbage, and lumber are collected by a refuse
<br />removal service and disposed of in a local landfill according to applicaE~le regulations governing such
<br />waste disposal. Petroleum products such as grease, lubricants and rr~iachine oil are collected by a
<br />licensed pickup Service for refinery recycling. See Tab 9, page 14'-28 and 14-29 of the permit
<br />application document. Non-coal waste materials have lazgely been removed from mine facility areas in
<br />association with reclamation projects during 2001 and 2002.

<br />VI. Coal Mine Waste and Non-Coal Processine Waste
<br />Information on coal processing waste and coal processing waste embankments can be found in Section
<br />2.05.3(8), Tabl3, of Volume 3 of the application.
<br />Three permittedirefuse piles, CRDA-I, CRDA-2, and RSRDA, h;tve been constructed to the
<br />specifications outlined in Tab 13 text, and in Appendices 13-4, 13,5 and 13-6 of the permit. See
<br />Exhibits 4, 5, 9A, 96, 18, 51, 52, 53 and 55, for further information. Reclamation of the refuse
<br />disposal areas is addressed in various sections of Tab 14, Volume 5, ilf the permit application, and
<br />reclamation specifications are depicted on Exhibits 6C, 9C, 26, and I E
<br />During mine operations, raw coal was processed at the preparation plant that was located within the
<br />Roadside South facilities area, and clean coal was conveyed to a unir: train loadout facility on the
<br />opposite side ofthe river, approximately a mile to the north. The rejeca material was transported by
<br />truck to the disposal sites in Coal Canyon (or the RSRDA pile prior to 1981). CRDA-2 has been fully
