RULE 2 PERMITS Stoker Coal Loadout Facility Details concerning the stoker coal loading facility can be found in Exhibit 15, Stoker Coal Facility, Map,21,- Existing Structures - North, Exhibit 7, Hydrology Information and Exhibit 8, Air Quality Information. Explosives Storage Area Details concerning the explosives storage facility are found in Exhibit 16 - Explosives Storage Facility, and Map 22, Existing Structures South. The storage facility is in compliance with all requirements of the Mine Safety and Health Administration, Bureau of Alcohol, Tobacco and Firearms and the Colorado Division of Mines. Loadout Colowyo's loadout, the Gossard Loadout, is located at the end of the Union Pacific rail line. The only segment of the spur within the permit area is shown on Map 22A, Existing Structures North. Power Lines Because Colowyo utilizes many electric - powered mining machines, a network of electric power lines is located in the permit area 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. A right of way from the BLM and the Colorado State Land Board was granted for the existing Tri -State 13 8kV running along the eastern portion of the permit boundary. The right of way includes a fifty foot corridor on either side of the powerline detailed on the Existing Structures Map (Map 22A and Map 22B). This permanent transmission line will stay in place after final bond release, as it is owned and maintained by Tri- State. The approximate acreage of this right of way is 7.748. Five major pieces of equipment at Colowyo, the three draglines, and two shovels are powered by electricity. 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. The location of the anticipated power line loop changes are also- shown on Map 22B, Existing Structures. In addition to power poles and lines, Colowyo will be using power cable to connect to the equipment that requires electricity (ie. Shovels, draglines, highwall miner, etc.). This is a rubber coated electrical cord that is used to run on top of the ground to convey electrical power from the substation to the electrical operated equipment for mining. If the corridor for the cable is covered with brush, making it inaccessible by a light vehicle, then the surface brush will be removed as a minimum. If not then the power cable will be placed over the surface without additional disturbance. In most cases topsoil will not be removed or salvaged due to the minimal impact to the environment. However, if necessary, the topsoil will be salvaged in either a windrow, stockpile, or placed on a regraded area ready for topsoil placement. The corridor of disturbance will generally be a dozer blade wide or approximately 25 feet. This allows for the cable equipment to access the corridor for placement and retrieval of the power cable. In addition this allows for small vehicle access for any maintenance activity that may arise. Rule 2 Permits 2.05 -8 Revision Date: 10/27/10 Revision No.: MR -103
