RULE 2 PERMITS Collom – Rule 2, Page 72 Revision Date: 4/28/22 Revision No.: TR-154 Anaylsis Laboratory, Emergency Vehicle Garage Please refer to Volume 1 Section 2.05.3. Crushing and Loadout Facilities The coal crushing and loadout facilities include two separate facilities: (1) primary crusher; (2) secondary crusher and train loadout; upon completion of coal production from the South Taylor pit the secondary crusher at the Gossard loadout may be removed. The primary crusher facility will be located in Section 36, Township 4 North, Range 94 West, as shown on Map 22B. Included in the primary crusher facility are a raw coal stockpile area, a truck dump, a primary crusher, a covered conveyor, a storage bin, and a truck load-out. Coal will typically be hauled from the pit in rear dump haulage trucks to the primary crusher site. The coal is then dumped directly into the truck dump hopper, or stockpiled. The truck dump hopper will be equipped with dust control spray bars. The coal from the stockpile can also be fed into the hopper by front-end loaders taking from the stockpile. Feeders at the bottom of the truck dump hopper discharge the coal into the primary crusher. Following primary crushing, the coal is discharged onto a conveyor belt which transports the coal to a storage bin. The coal is then gravity discharged into highway trucks and hauled to the secondary crusher facility. The secondary crusher and train load-out facility is known as the Gossard Loadout and is located in Section 22, Township 4 North, Range 93 West, and is described in Section 2.05.3 in Volume 1. Explosives Storage Area The Collom area explosives storage facilities are shown on Map 22B, and will meet or exceed all MSHA and BATFE regulations. Overall volume of high explosives used by Colowyo collectively while mining activities transition over time from the existing operation to the Collom area exlusively logically dictates the number, capacity and configuration of the Collom facility magazines be similar existing facility to ensure sufficient magazine capacity is available at the time peak utilization of high explosives in the Collom area will occur. This logical approach is also applied to the ammonium nitrate, emulsion and Type V magazine storage area also identified on Map 22B. As these structures contain blasting materials and not high explosives, specific requirements governing their management are different and as such are separated by location from the high explosives storage area. Loadout Colowyo's loadout, the Gossard Loadout, is located at the end of the Colowyo’s 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 electric-powered mining machines power lines will be located in the permit area to supply electricity to the equipment and facilties. The location of the supporting power lines within the Colowyo existing permit area is included in Volume 8, Map 22A. Power lines for the Collom expansion area are shown on the Structures and Facilities map (Map 22B). The 69kV power line that is routed through the permit boundary to the Collom facilities area will be owned, operated, maintained by White River Electric Assoication (WREA) not Colowyo, and will remain in place to service the area post-
