RULE 2 PERMITS • Other surface treatments are also described in Volume I, section 2.05.4. A list of the equipment used by Colowyo in order to perform the day-to-day operation of coal mining is shown in Volume 1, Table 4, Equipment List and in Table 2.05.2-1. 2.05.3 (2) Operation Description A detailed narrative description of the land to be affected within the South Taylor area is provided' above under the heading Production Methods and Equipment. The mining plan for South Taylor is graphically portrayed on the Mine Plan Map (Map 23A). The various acreages to be affected by the planned mine operation aze shown in Volume 1, Section 2.03 on Table 1, Affected Areas for Mining and Reclamation. The details ofthese operations for South Taylor are shown on the Mining Range Diagram (Map 24A). The lines on Map 23A refer to coal seam mining, the lines on Map 28B, Topsoil Handling, refer to the anticipated overall disturbance that not only includes coal mining, but also associated perimeter disturbances as well. 2.05.3 (3) Mine Facilities The existing buildings, structures, utility corridors and other facilities are shown on the Existing Structures -North Map (Map 21), Existing Structures -South Area (Map 22) and Existing Structures South Taylor Area (Map 22A). Colowyo only anticipates the need for a minimal amount of major structures within the South Taylor area, which will include the installation of utility lines, water lines and in-pit haulage routes. No out of pit haul roads are anticipated. All other support facilities are located on maps 21 and 22, which will continue to be used for the life of mine. • Please refer to Volume 1, Section 2.05 for a complete description of Operational procedures within the permit boundary including the South Taylor area. Power Lines Because Colowyo utilizes many electric-powered mining machines, a network of electric power lines is located in the permit azea to supply electricity to the equipment. The locations of the Colowyo power lines are shown on the Existing Structures maps (Map 22A and Map 22B). Electrical power lines located in the permit area will be constructed in accordance with requirement of Section 4.18 to minimize potential electrical hazards to large raptors. The major pieces of equipment that are powered by electricity and will be used in the South Taylor area are draglines, shovels and the highwall miner. Therefore, during the life of the mine it is necessary to periodically move the existing power line loop to accommodate the advancement of the pit. Along the western limits of the South Taylor pit operations, highwall mining activities will be conducted to extract coal that would otherwise be deem non-recoverable under existing operational procedures and economic conditions. See Map 23A for the location of the area to be mined. • South Taylor/Lower Wilson -Rule 2, Page 96 ReviSlOn Date: 3/30/07 Revision No.: PR-02
