Minor storage of materials, equipment, and supplies may occur throughout the mine site. Examples <br />of such storage include roles of conveyor belt at transfer stations, straw bales and mulching <br />materials commensurate with their use, clean rock for rip-rap and sediment control. Temporary <br />storage of equipment, materials, and supplies will also be allowed adjacent to facilities to facilitate <br />construction and repair on an as-needed basis. <br />Other storage areas for equipment and materials include the 'blisters' along the haul road. Blister <br />#2 (a.k.a. Treasure Island) serves as storage for outdated equipment, parts, and materials awaiting <br />salvage and sale. Blister #3 has been designated for road base storage. Other materials and <br />equipment such as reclamation materials, drill steel, water pipe, and contractor equipment and <br />supplies may also be stored on the blisters. These blister areas are not to be used for the storage <br />of liquids or other materials in a manner that could damage fish, wildlife, and related environmental <br />values. <br />More specific locations and containment structures are maintained for petroleum and liquid <br />materials. Such liquid storage areas are identified on Map 15 for the D-Portal Area. <br />Other bulk liquid storage facilities include the fuel storage at the dozer shop currently located at <br />Refuse Area 5a (peVoleum), deicing storage tank by the loadout, underground bulk fluid storage at <br />SH-2 near the B-Vent Shaft #2, and the hydrochloric acid tank by the water treatment facilities. <br />Magnesium chloride, or other chemical road dust suppressant, is stored on an as-needed basis in <br />tanks placed at the entrance to 'blister' #2 in a location draining to sediment pond DP-1. Limited <br />quantities of containerized reagents and petroleum products also occupy many of the various <br />buildings scattered throughout the mine site. LPG bulk tanks are also located north of Slot Storage. <br />Water storage facilities are discussed elsewhere but include the raw water tank, potable water tank, <br />and the lagoon. <br />Explosive storage is provided in a suitable licensed location at the end of the road past sediment <br />pond DP-1. <br />Used oils, greases, antifreeze and solvents are retained for recycling. Bulk storage tanks are <br />available for used oils and antifreeze at the west end of the mine maintenance shop. Used <br />chlorinated solvents are returned to their original containers far recycling or continued use by the <br />supplier. Drums and barrels containing used or obsolete liquid products are stored at the petroleum <br />barrel storage southeast of the D-Portal prior to being sent off for recycling or being reassigned <br />another use. Empty barrels are also stored next to this location prior to crushing and placement in <br />the scrap metal receptacles for recycling if they are not to be returned to the vender for <br />reconditioning or reused on site. <br />Technical Revision #fi4 (4/2007) IV-54 <br />
