DJRAY SILVER MINES <br /> The mine will have general locations for regent storage and handling, as the current mill reagent room is <br /> permitted as an EPF and the entire reagent room is being proposed as an EPF. While storage within the <br /> designated usage area is preferred, conditions such as equipment maintenance,fluctuating storage <br /> volumes, and handling/maneuverability challenges associated with large packages, could create <br /> employee hazards in the absence of alternate storage or staging locations. The current and proposed <br /> reagent facilities have the appropriate secondary containment to safely store designated reagents. OSMI <br /> commits to the immediate offloading of chemicals to one of the two reagent facilities, though chemicals <br /> may be incidentally present in common areas of those EPF locations rather than solely in the usage area <br /> specific designated chemical. <br /> 11. Please provide details regarding how chemicals will be moved throughout the Reagent <br /> Room to their desired location, Pursuant to Rule 6.4.21(6)(b)(i). Forklift, dolly, by hand. <br /> How do you get into the containment structures? <br /> Materials will be offloaded from trucks and moved by forklift into the reagent room only by employees <br /> who have been trained on the hazards and handling of designated chemicals. Training documentation <br /> will be retained on site by the safety department. There are ramps that will be used to access the <br /> Reagent Room which the forklifts will be able to drive on and into the facility. <br /> 12. Page 7 of TR-14 states "Due to the short shelf life, chemicals will be removed from the <br /> mine site under temporary cessation". Under Rule 1.13.2, the mine site could still be <br /> considered actively mining without having a need for/or authorization to conduct milling <br /> operations (i.e. need to use the Reagent Room). What is the approximate term of <br /> cessation of milling operations that would constitute a need for chemicals to be removed <br /> from the site?Address Rule 6.4.21(6)(b)(i). <br /> Within 6 months of entering Temporary Cessation then the reagent chemicals would be removed from <br /> site. The chemicals would either be returned to the manufacturer or disposed of by a certified waste <br /> disposal service. <br /> 13. How will equipment that comes into contact with the chemicals in Table 1 be detoxified <br /> and/or disposed of? - Pursuant to Rule 6.4.21(6)(b)(i) <br /> a. Are there any special precautions for PPE disposal, replacement of equipment, <br /> flowlines, etc? <br /> There are no special precautions for disposal in the SDS sheets. It is unlikely that any equipment will need <br /> to be detoxified due to the nature of the chemicals. For any equipment or PPE that needs to be replaced, <br /> the item will be rinsed with water that reports to the process water tank via sumps. Should the process <br /> water tank need to be drained, the liquid will be disposed of at an approved facility-such as thermal <br /> treatment or incinerations. The rinsed equipment will then be disposed of according to best management <br /> practices and SDS specifications. <br /> b. Provide details regarding the procedure for tracking and storage of chemicals until <br /> they can be returned to the manufacturer or properly disposed of. <br /> 4 1 P a e <br />
