The table includes the list of designated chemicals used in the froth flotation metallurgical process for concentrating MoS and for informational purposes, also lists water treatment chemicals that will also be used on site. A portion of these chemicals are not currently stored onsite, but may be located on site during periods of production. Future storage locations of chemicals not currently on site are provided based on best available information. The individual reagent tank volumes are presented in Table T -2 and their locations are illustrated on Figure AM- 06 -T -06. There are two enclosed reagent storage rooms within the mill building. There are three tanks in one room; the collector, frother and iron depressant tanks. The largest of these tanks is 13,500 gallons, or approximately 1,800 ft The total maximum volume of reagents stored in this room is 32,800 gallons, or approximately 4,400 ft As illustrated on Figure AM- 06 -T -06, this room has a total spill containment capacity of approximately 44,000 gallons, or 5,900 ft The other room contains one tank, the liquid Nokes (iron /lead /copper depressant) tank, whose size is 18,000 gallons, or approximately 2,400 ft with a spill containment capacity of approximately 29,000 gallons, or 4,000 ft All the reagent storage tanks are vented to atmosphere within the reagent area. In addition, the liquid Nokes tank has a powered vent to the outside of the building. Table T -2: Designated and Other Chemicals at the Climax Mine EPP: Version R2 T -8 December 2011
