Station, and in the mill building. Lime is a common, but strong caustic alkali. In high <br /> concentrations, lime can cause caustic irritation, inflammation, and bums through inhalation and <br /> dermal contact. <br /> Excessive amounts of lime in the environment can raise alkalinity to damaging levels. In aquatic <br /> systems, excessive lime also can cause potentially damaging precipitation/sedimentation. <br /> Coherex <br /> Coherex is a petroleum hydrocarbon in water emulsion used widely in earth disturbing activities <br /> to control dust and wind erosion. At Climax, it is applied annually to exposed tailing to control <br /> dust from the tailing impoundments and dams. Since the Robinson and Mayflower <br /> impoundments have been capped, Coherex is used primarily on the Ten Mile impoundment and <br /> No. 3 Dam. <br /> Coherex has a slight toxicity rating, and insignificant ratings for fire and reactivity. When burned <br /> it releases carbon monoxide and carbin dioxide. It should be segregated from strong oxidizers. <br /> Effects on human health are similar to other common petroleum distillates such as diesel fuel. <br /> • Coherex spills into the environment should be controlled and handled as with other petroleum <br /> products. The spill should be controlled and isolated with sorbents and other inert materials such <br /> as soil, sand, or vermiculite. If spills occur in the aquatic environment, sorbent booms can be <br /> used for containment prior to skimming the product from the surface. <br /> 3.3 Material Safety Data Sheets for Designated Chemicals <br /> Material Safety Data Sheets (MSDS) are attached in Appendix A. These data sheets list <br /> permissible exposure limits, monitoring and measurement procedures, health hazard information <br /> and exposure effects, recommended medical procedures for human exposure, emergency first aid <br /> procedures, personal protection, leak and spill procedures, and waste disposal methods. More <br /> detailed information and site specific handling procedures are discussed in Section 4.0 and in <br /> Appendix B. <br /> 4.0 Designated Chemicals and Materials Handling <br /> The Climax SPCC/MCP (Appendix B) provides a consolidated plan for the handling of <br /> • designated chemicals and process water at the Climax Mine. This plan has been certified and was <br /> prepared pursuant to Part I.E.I.g of the CDPS Permit as required by the CDPHE. The plan also <br /> 11 <br />
