<br />Climax Molybdenum Company HENDERSON MINE & MILL SWMP <br />Empire & Parshall, CO December, 2011 <br />Page 4-2 <br />Table 4.1, Description of Potential Pollutant Sources <br />PS # Potential <br />Pollutant Location Purpose Outfall <br />Likelihood <br />of Contact <br />with Storm <br />Water <br />Basis <br />1 Potable water <br />treatment chemicals. <br />Potable Water System Filtration and disinfection of the <br />mine’s domestic water supply. <br /> OF-8b <br />(Butler Gulch) <br />Unlikely Spills could report directly to Butler Gulch. Drain has been blocked and chemicals used for <br />chlorination are stored within containment. <br />2 Miscellaneous <br />Contaminates <br />Underground <br />Warehouse Adit <br />(floor drain) <br />Temporary storage of equipment <br />for shipment underground. Stored <br />items include wood pallets, <br />conveyor rollers and tires. Former <br />explosive magazines. <br /> 0F-8a <br />(Butler Gulch) <br />Unlikely Groundwater seepage into bays of magazine and drainage trenches may become polluted by stored <br />product. The explosives magazines at this location are no longer used. Inclusion of this potential <br />source in the Plan is maintained in case such use is renewed in the future. <br />3 Ethylene Glycol- <br />50/50 Mix (antifreeze) <br />Compressor Cooling <br />Station/Storage Tank <br />The heat exchangers for <br />compressors and associated tanks <br />contain antifreeze. <br />OF-2 <br />(W. Fork Clear Creek) <br />Unlikely Floor drains are plugged and leaks inside building would not flow out. Contaminated water that <br />collects in the building would be pumped into wastewater system or taken off-site. Uncontained <br />leaks would report to sheet flow of paved area and eventually to Outfall OF-2. <br />4 Cement and fly ash <br />particulates. <br />Cement and Fly Ash <br />Silos and Unloading <br />Area <br />Storage and unloading of cement <br />and fly ash associated with batch <br />plant. <br />OF-2 <br />(W. Fork Clear Creek) <br />Probable Spill of product exposed to storm water would flow west across pavement and would eventually <br />report to Outfall OF-2. <br />5 Misc. Contaminates <br />associated with non- <br />hazardous waste and <br />recyclable products. <br />Waste Sorting and <br />Recycling Facility west <br />of #2 Shaft <br />Collection and temporary storage <br />of mine wastes prior to <br />transportation off-site. Also <br />includes a trash compactor, trailers <br />for recycling steel and other <br />materials, and a salvage wood pile. <br />OF-8a <br />(Butler Gulch) <br />Unlikely Materials that could be eroded and carried by storm water would report to Outfall OF-8a. <br />6 Hazardous wastes <br />and/or petroleum <br />products. <br />Hazardous Waste <br />Collection/Storage <br />Dock. <br />Storage of hazardous waste. OF-3 <br />(W. Fork Clear Creek) <br />Unlikely Sloped floor would likely hold the volume of a drum. Floor dry is in the area to use in case of a <br />spill. <br />7 Sediment, chemicals, <br />oil, diesel fuel, pipe <br />debris and lubricants. <br />West Lay-down Yard Storage yard and temporary <br />staging area. <br />OF-1, OF-8c <br />(Butler Gulch) <br />Likely Unattended equipment scheduled for salvage, sale, long term storage or repair could have the <br />potential for oil and fuel leaks that could report to Outfalls OF-1 and/or OF-8c. <br />8 Sediment Sand and Gravel <br />Storage Pad <br />Gravel and sand for winter road <br />work. <br />OF-2, OF-9, OF-15, <br />OF-16 <br />(W. Fork Clear Creek) <br />Probable Sediment could be carried by storm water to lower portion of surface area and report to Outfalls <br />OF-2, OF-9, OF-16 and/or OF-15. <br />9 Oil, diesel fuel, and <br />lubricants. <br />Salvage & Equipment <br />Yard/Warehouse and <br />Truck Scale <br />Storage of lumber, pipes, good <br />steel, new fill material, and <br />unattended vehicles scheduled for <br />salvage, sale, long term storage, or <br />repair. Warehouse contains new <br />product (oil and lubricants). <br />0F-7, OF-14 <br />(Butler Gulch) <br />Likely Unattended vehicles scheduled for salvage sale, long term storage or repair, or using the truck scale <br />could have the potential for oil and fuel leaks that could report to Butler Gulch in sheet flow west <br />of Outfall OF-7 and/or OF-14. Warehouse building has an elevated concrete footer that would <br />contain liquid in the event of a spill inside the building. Building containment capacity exceeds the <br />volume of the largest single container in the storage area.
