Project DescriptionThe airstrip will be constructed from rock fill, with a minimum of 1 m fill placed over theoriginal ground without stripping. Where necessary, ditches will be constructed to divert runofffrom adjacent land into existing watercourses. Ditches will be graded to avoid ponding ofsurface water next to the embankment, which would cause melting of the permafrost.2.6.4 Tank FarmsFuel trucks will deliver fuel from the port to tanks located at the mine site on a regular schedule.An estimated total of 5 million litres of fuel will be stored at the Hackett River fuel tank farm.For this purpose, two 2.5 million-litre storage tanks will be installed in a lined containmentfacility.2.6.5 ExplosivesAs described in the mining section, the supply of explosives will be provided by a third party thatwould manufacture emulsion explosives on site and deliver the product to the blast hole asrequired. Under normal operating conditions, it is envisioned that a limited supply of emulsionexplosives would require storage on site at any one time. Blasting accessories and miscellaneousexplosives products would be supplied via the port at Bathurst Inlet and stored on site.2.6.6 Hazardous MaterialsA variety of supplies and materials classified as potentially hazardous will be required at the mineand mill for general operations. Materials will be backhauled from the port site on an ongoingbasis. The largest volume hazardous materials to be handled will include the following:To The Mine:• Petroleum Products (diesel fuel, gasoline, lubricants, hydraulic fluids, oil and solvents)• Propane• Explosives• Ammonium Nitrate• Mill Reagents (e.g. MIBC, ZnSO 4 , NaCN, and quicklime)From The Mine:• Copper/lead/zinc concentrates• Waste Batteries• Waste Oil• Waste Solvents• Empty petroleum and reagent drums, carboys, and pailsA Hazardous Materials Handling Plan will be in place to identify and monitor potentiallyhazardous materials that will be used at the site with regard to safety and environment.Transportation, storage, use and ultimate disposal will be considered. Safety of the workers andthe surrounding communities will be taken into account for all stages of materials handling.January 2008 Hackett River Project – Project Proposal Sabina Silver CorporationReport Version B.1 2–29 Rescan Environmental Services Ltd.
