systems, brake shoes, and some car body work. A 30-ton crane handles maintenance on the cars and <br />locomotives. Major repairs are not performed at the facilities, however major replacements of compon- <br />ents are performed. <br />IV.D Waste Transportation and Disposal Facilities <br />IV.D.1 Waste Materials Table IV.D-1 indicates the types and major sources of solid waste material that <br />are to be generated during mine operations exclusive of preparation plant refuse (coal fines and rock). <br />The trash waste is buried in a sanitary landfill owned and operated by BME for the exclusive use of <br />Deserado Mine trash waste disposal. Trash waste includes large timbers, large pieces of metal, paper, <br />rags, garbage, filters and used parts. Generally, solid wastes collected at the portal entries or from the <br />general trash receptacles at the various buildings will be placed in the sanitary landfill. Waste is also <br />hauled from the site and dumped into the county sanitary landfill by a contract Vash hauler. <br />Rock debris, coal processing wastes, small pieces of metal and sediment are disposed of in the coal <br />refuse areas. Material collected in the preparation plant refuse hopper, process ponds, and sediment <br />ponds are put into the coal refuse area. Some sorting of material is required at the surge bin trash <br />grizzly. <br />IV.D.2 Transportation Svstem The coal processing waste (CPW) transportation system starts at the <br />refuse hopper adjacent to the preparation plant, the 150-ton surge bin and breaker trash bins. It <br />includes the refuse haul road, disposal area and the equipment used to haul and place the refuse. <br />The Refuse Haul Road was designed before Colorado gained primacy for surface inspection and <br />therefore the original design and referenced standards are from 30 CFR part 817. The referenced <br />standards have also been re-numbered since that time. Presently, the appropriate Federal standards <br />appear now to be 30 CFR 817.150 and 817.151. The corresponding DMG standard is 4.03.1. <br />The alignment and profile of the road are as indicated on Maps 56 through 67. Excluding the <br />tum-around loop at the preparation plant, the road extends approximately 30,400 feet from the point <br />under the refuse hopper to the extreme end of the Refuse Disposal Area. Traffic on the road is <br />iwo-directional. Therefore, the road design utilizes the 2-lane design cross-section set forth in the <br />Bureau of Mines Information Circular-IC-8758-1977 entitled "Design of Surface Mine Haulage Roads-A <br />Manual". Haul road cross-sections are shown on Maps 67 and 68. The cut and fill slopes and road <br />surface comply with Section 4.03.1(3). Maximum cut slopes used in unconsolidated materials are not <br />steeper than 1.5h:1v and 0.25:1v in rock. The actual cut slopes used were determined during <br />construction. Maximum fill slopes are not steeper than 1v:2h. Cross sections of the maximum cuts and <br />fills along the haul road and road and plant access road are shown on Map 68. The design criteria used <br />for location, vertical and horizontal alignment are as set forth in Section 4.03.1(3). The maximum grade <br />used on the haullplant access road w.as 5.8 percent and the minimum curve radius used was 500 feet. <br />Mine Permit Renewal #3 (Rev. 8/99) IV-13 <br />
