Technical Revision (TR -28) <br />Environmental Protection Plan <br />Climax Molybdenum Company <br />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 <br />Product <br />Prod <br />Storage <br />Tank <br />Secondary <br />Type & <br />Name <br />Storage Location <br />Container <br />Storage <br />Containment <br />Use <br />Type <br />Ca acit <br />Designated Chemicals <br />Nalco 9866 / <br />Reagent Area 450 <br />One tank (and <br />Collector <br />Calumet <br />and Floatation Area <br />300 gallon totes <br />13,500 <br />Yes <br />Hydrocal 60 <br />430 (when totes <br />when needed) <br />gallons <br />or similar <br />used) <br />Collector <br />Tergitol NP -4 <br />Floatation Area 430 <br />55 gallon <br />3 drums, — <br />Yes <br />Dispersant <br />Surfactant or <br />drums <br />165 gallons <br />similar <br />Nalco Froth <br />Reagent Area of <br />One tank (and <br />Primary <br />Pro or <br />Mill —Area 450 and <br />gallon totes <br />9,300 <br />Yes <br />Frother <br />similar <br />ar <br />Floatation Area 430 <br />when needed) <br />when <br />gallons <br />(when totes used) <br />Reagent Area 450 <br />Cleaner <br />CorsiTech <br />and Floatation Area <br />One tank (and <br />Frother <br />FrothPro 327 <br />430 (when totes <br />300 gallon totes <br />600 gallons <br />Yes <br />or similar <br />used) <br />when needed) <br />Reagent Area 450 <br />One tank (and <br />Iron <br />Orfom D8 or <br />and Floatation Area <br />gallon totes <br />10,000 <br />Yes <br />Depressant <br />similar <br />430 (when totes <br />w h needed) <br />gallons <br />used)when <br />Reagent Area 450 <br />Lead and <br />and Floatation Area <br />One tank (and <br />18,000 <br />Copper <br />Nokes <br />430 (when totes <br />300 gallon totes <br />gallons <br />Yes <br />Depressant <br />used) <br />when needed) <br />FloatSilTM <br />300 gallons <br />7 totes, <br />Surfactant <br />(sodium <br />Floatation Area 430 <br />totes <br />2,100 <br />Yes <br />silicategallons <br />Calumet <br />Hydrocal 60, <br />— 10 totes, <br />Froth <br />Modifier <br />PPG- <br />2000/4000, <br />Floatation Area 430 <br />300 gallon totes <br />3000 <br />Yes <br />Nalco 7561, <br />gallons <br />or similar <br />Polymer <br />Dry bulk bags, <br />Ventures <br />one mix tank <br />Flocculent <br />DAF -30 or <br />Floatation Area 430 <br />and one <br />8250 lbs. <br />Yes <br />similar <br />storage tank <br />EPP: Version R4 T-8 August 2018 <br />
