<br />CGM - MCP <br />November 2024 8 <br /> <br /> <br />Part 3: Material Movement and Storage <br />3.1 Transportation <br />The chemicals used in the water treatment process will be delivered to the mine site by highway trucks. <br />The chemicals used will be delivered, transported to the mill and stored in their factory containers. <br />Once onsite, the chemicals will be unloaded in the designated area. This area is within the CONEX <br />containing the water treatment equipment. Occasional reagent storage may occur outdoors in a <br />designated area. A small forklift or skid-steer will be used to unload the truck and transport the material <br />to it designated location. The overall process of unloading and transportation will occur as quickly as <br />possible while maintaining safe operations. This will reduce the exposure to potential spills outside of <br />containment. <br />3.2 Storage <br />Once the materials have been transported to their designated storage area, they will be stored in their <br />factory containers until used. Storing the materials in the CONEX is ideal as it is cool, dry and out of <br />direct sunlight. Following is a discussion on the storage of each chemical: <br />3.2.1 MetSorb HMRG <br />MetSorb HMRG should be stored in a dry, cool, well-ventilated place. Store in the original container <br />away from moisture. <br />MetSorb HMRG is considered to be stable and non-reactive. It is a dry, white powder or granule with no <br />odor. <br />MetSorb HMRG can cause eye damage, skin irritation, and respiratory irritation. <br />MetSorb HMRG is used to adsorb heavy metals from mine water during filtration. <br />3.3 Containment <br />Unloading of designated chemicals will take place via end doors of the CONEX. Designated chemicals <br />may be stored outside in a lined storage area. <br />All chemical storage will be within a lined basin capable of containing 110% of the largest liquid volume <br />stored within the basin. Acceptable basin types are: <br />• Single piece welded steel trough or half-barrel <br />• PVC/HDPE liner overlaying concrete or steel barriers of at least 6-inches in height. <br />• Precast concrete basin with lip. Lip must be at least 3-inches in height. Concrete must be sealed <br />with epoxy or similar liquid seal <br />Spill kits must be maintained within 10-feet of any reagent stored according to this plan. Spill kits must <br />contain: <br />• Nitrile safety gloves <br />• Eye goggles <br />• Poly apron(s) <br />• Shoe or boot covers <br />• Sorbents and absorbent pads <br />• Disposal bags or bins <br />• Scoops or shovel <br />• Neutralizing agent
