5.4.5 McNulty Lime Station (Lime Slaking Facility) <br /> Description: The McNulty Lime Station consists of three Wallace and Tiernan a t - <br /> p Y p s e slakers, <br /> three storage silos, a water storage tank, equipment building, a conveyor system, and a water <br /> well. <br /> Location: The McNulty Lime Station is located west of Highway 91 and east of No. 2 Dam. <br /> Spill Potential: Although not likely, a spill of slaked lime or crushed limestone is possible from <br /> loading operations at the facility. <br /> Potential Volume Spilled: Under extremely unusual circumstances, a storage silo containing up <br /> to four truckloads could conceivably topple over and spill its contents. More likely, however, is <br /> a spill of 50-100 pounds of granular material from a loading truck. <br /> Prevention and Control: Operator care at the unloading point is the best spill prevention. <br /> Countermeasures: Scooping up the lime with a hand shovel and replacing it in the fill tube or <br /> on the truck is the best way to clean up a typical lime spill. For larger spills, on the order of <br /> several hundred pounds (or more), a skid loader or endloader might be required. <br /> Nearest Clean-up Equipment: Shovels are routinely carried in the foremen's trucks or can be <br /> obtained in the Warehouse. Skid loaders and endloaders are available throughout the mine <br /> operating area. <br /> Monitoring: The McNulty Lime Station is checked daily during mine operation, and on a <br /> weekly basis when the mine is idle. <br /> Reporting: Any spill of more than 100 pounds of lime* should be documented immediately <br /> using the "Spill Incident Report" form (Appendix 1), and given to the Environmental <br /> Coordinator. Any spill which threatens waters of the State of Colorado is subject to the reporting <br /> requirements given in Sections 4.2, 4.3, and 4.4 of this SPCC Plan. <br /> *Lime is not considered an environmental threat; in fact, large quantities are utilized throughout <br /> the Climax minesite to control acid mine drainage. Therefore, reporting all spills is not <br /> particularly useful, because lime is added to the system on a daily basis anyway. <br /> 63 <br />
