Technical Revision (TR-28) Climax Molybdenum Company <br /> Environmental Protection Plan Permit No. M-1977-493 <br /> storage tanks within the reagent storage rooms (Area 450) are vented to atmosphere. Climax also stores <br /> containers (totes and/or drums) of designated chemicals on the floor of the mill building (Area 430), and <br /> may temporarily store containers in the Climax warehouse. <br /> Secondary containment for designated and other chemicals is achieved by use of containment structures <br /> (Area 450), spill pallets (warehouse and Area 430), concrete floors/sumps (Area 430). Building perimeter <br /> infrastructure/ditches/berms also provide tertiary containment. Specific containment details for the <br /> reagent storage rooms (Area 450) are shown on Figure AM-06-T-06. <br /> Table T-2: Desi nated and Other Chemicals at the Climax Mine <br /> Chemical Prod Storage Tank Secondary <br /> Type& Product Storage Location Container Storage Containment <br /> Use Name Type Ca acit <br /> Designated Chemicals <br /> Nalco 9866/ Reagent Area 450 One tank (and <br /> Collector Calumet and Floatation Area 300 gallon totes 13,500 Yes <br /> Hydrocal 60 430 (when totes when needed) gallons <br /> or similar used) <br /> Collector Tergitol NP-4 Floatation Area 430 55 gallon 3 drums, — Yes <br /> Dispersant Surfactant or drums 165 gallons <br /> similar <br /> Reagent Area of <br /> Primary Nalco Froth Mill—Area 450 and One tank (and 9,300 <br /> Frother similar Pro ar or Floatation Area 430 when <br /> gallon totes gallons Yes <br /> (when totes used) when needed) <br /> Reagent Area 450 <br /> Cleaner CorsiTech and Floatation Area One tank (and <br /> Frother FrothPro 327 430 (when totes 300 gallon totes 600 gallons Yes <br /> or similar used) when needed) <br /> Reagent Area 450 One tank (and <br /> Iron Orfom D8 or and Floatation Area 10,000 <br /> Depressant similar 430 (when totes h gallon totes gallons Yes <br /> w <br /> used) when needed) <br /> Reagent Area 450 <br /> Lead and and Floatation Area One tank (and 18,000 <br /> Copper Nokes 430 (when totes 300 gallon totes Yes <br /> Depressant used) when needed) gallons <br /> FloatSilTM 300 gallons 7 totes, <br /> Surfactant (sodium Floatation Area 430 totes —2,100 Yes <br /> silicategallons <br /> Calumet <br /> Hydrocal 60, — 10 totes, <br /> Froth PPG- Floatation Area 430 300 gallon totes —3000 Yes <br /> Modifier 2000/4000, <br /> Nalco 7561, gallons <br /> or similar <br /> Polymer Dry bulk bags, <br /> Ventures one mix tank <br /> Flocculent DAF-30 or Floatation Area 430 and one 8250 lbs.
