RULE 2 PERMITS <br /> <br />Rule 2 Permits 2.05-28 Revision Date: 8/6/25 <br /> Revision No.: PR-05 <br />changing weather conditions and the use of heavy haulage trucks. <br /> <br />Colowyo has surfaced “in-pit” roads with gravel or crushed rock; however, no roads in the pit area <br />will be paved with asphalt. Asphalt could not sustain the enormous weights of the haulage <br />equipment currently in use. Likewise, crawler equipment would rip the asphalt surface causing an <br />extremely hazardous condition for all equipment and personnel. All roads in the mining operation <br />will be constantly maintained by a motor grader, scraper, or rubber tired dozer to remove any coal, <br />rock, or any other debris. Smooth and clean road surfaces are essential for not only minimizing <br />dust, but also for allowing efficient, safe and economic use of haulage equipment. <br /> <br />The haul roads have been paved with asphalt to provide for emission control. The paved roads <br />include approximately five miles of road from State Highway 13to the main office building, the <br />road from the main office building to the Gossard coal loadout, and the road from the shop facility <br />to the Gossard coal loadout. <br /> <br />A strict speed control will be implemented for all roads to control dust and to provide for safe <br />operation of the equipment. <br /> <br />Most haul road embankment slopes and adjacent areas have been mechanically stabilized and <br />seeded with a mixture shown in Table 7, Reclamation Seed Mixture. Mechanical stabilization has <br />consisted of furrowing, chiseling, "cat tracking" and mulch, depending on accessibility to the <br />slopes. <br /> <br />No travel of unauthorized vehicles will be allowed on anything other than established roads. All <br />overburden haulage equipment will be restricted only to appropriate roads. <br /> <br />Colowyo does not plan to cover any of the haul trucks because the roundtrip between the coal <br />crushing facility and the active mining area will be relatively short, and the loaded trucks will <br />be moving slowly. Also, care will be taken by the front-end loader or shovel operators not to <br />overfill any of the haul trucks so as to cause excessive fugitive dust. <br /> <br />Coal Crushing Facility <br /> <br />Coal will be hauled from the various mining areas in haulage trucks to the primary crusher <br />facility as shown on the Existing Structures - South Map (Map 22). Following primary crushing, <br />the coal is hauled to the Gossard Loadout facility, as shown on the Existing Structures - North <br />Map (Map 21). <br /> <br />The coal crushing and conveying operations at the primary crusher and the Gossard Loadout <br />have been equipped with a water spraying system at all coal transfer points. A four-sided <br />enclosure-bas-been installed on the truck dump at the primary crusher to prevent excessive dust <br />emissions. The secondary crusher at the Gossard Loadout has a bag house to control coal dust <br />emissions. A stacking tube with metal doors is also used to minimize coal dust emissions at the <br />100,000 ton crushed coal stockpile. The air quality control measures at the coal crushing handling <br />and loadout facilities have been approved by the Colorado Department of Health, Air Pollution <br />Control Division.
