TR-34 to Permit M-1977-342 <br /> Environmental Protection Plan <br /> quicklime, but may still release heat upon mixing. Contact with eyes can cause severe irritation <br /> or burning, including permanent damage. <br /> In the presence of acidic conditions such as acid rock drainage or acid mine drainage, hydrated <br /> lime reacts as an acid neutralizer and buffer. It can be used to raise the pH of acidic waters. Should <br /> hydrated lime be delivered directly into a non-process water or a non-acidic water environment, <br /> it would cause short-term impacts to aquatic communities by raising the system pH. Direct long- <br /> term impacts would be negligible to non-existent since calcium hydroxide would neutralize in the <br /> natural system and does not bio-accumulate. <br /> DAF-10 Flocculant will be used in the Mill WTP to promote precipitation of metals. The resulting <br /> precipitate or sludge is thickened and removed from the treatment system using a clarifier. <br /> Ultimately, waste sludge will be conveyed to the TSF for disposal. The product does not contain <br /> any hazardous components and is non-reactive, non-flammable, and a slight human health <br /> hazard. Eye protection and gloves should be worn when in contact with the product. Avoid <br /> inhalation of vapors or mist. Product produces extremely slippery surfaces when wet. In the <br /> environment, DAF-10 is stable and non-hazardous. <br /> Carbon Dioxide will be used for effluent neutralization in the Mill WTP. It is an extremely cold <br /> liquid and gas under pressure and may cause frostbite upon skin contact. Eye protection and <br /> gloves should be worn when in contact with the product or product containers. Ingestion is not <br /> considered a potential route of exposure. Store in a cool, well-ventilated place. In the <br /> environmental, released carbon dioxide will disperse into the atmosphere. <br /> 5.3. Safety Data Sheets for Designated Chemicals <br /> SDSs for designated chemicals are included in Appendix C. SDSs are maintained at the Mine and <br /> Mill and can be accessed by employees should information be required for emergency response <br /> procedures. <br /> Climax Molybdenum Company August,2021 <br /> Henderson Operations Page 13 of 45 <br />
