In 1987, the two underground fuel storage tanks located by the office (Map M13) were replaced by one <br />15,000-gallon above-ground gasoline tank. The old tanks were removed and disposed of. In 1990, all <br />remaining underground storage tanks were replaced with aboveground tanks. <br />The aboveground tanks are not scheduled to be removed until the coal reserves are exhausted. Addi- <br />tional fuel tanks may be installed if fuel supply conditions warrant. <br />Exolosives Storage Areas: <br />Explosive storage areas consist of three explosives magazines, four ammonium nitrate silos and a <br />10,000-gallon above-ground emulsion tank. <br />The three explosive magazines are steel with wood lining. All detonators are stored in the northern-most <br />small magazine (8'x8'x10'). All 3.5x6 bagged slurry products are contained in the southern-most large <br />magazine (8'x8'x40'). Boosters and Det-cord are stored in the remaining small magazine (8'x8'x10'). The <br />8x50 packaged emulsions are stored in semi-trailers near the magazine in a fenced and locked enclosure. <br />In 1988, a 30-ft x 36-ft truck storage shed was constructed within the explosives magazine storage area to <br />provide a protective parking area for the Anfo trucks. The entire explosives magazine storage area is <br />fenced and locked when not in active use. <br />The ammonium nitrate silos are built of steel. In 2002, ammonium nitrate silos #1 and #2, along with new <br />silo #4, were relocated from a site at the intersection of the D pit and B/C pit haulroads to a new site along <br />the life-of-mine haulroad near East Flintlock pit, The 10,000-gallon aboveground emulsion tank was also <br />relocated from the B/C Pit area to the new site near East Flintlock Pit (MR-186). The emulsion tank is <br />surrounded by an impermeable earthen berm of sufficient size to contain the entire contents of the tank <br />should a major breach occur. Siio #3 is located in the old B/C pit area by the waste accumulation site. <br />These structures are not scheduled to be removed until the coal reserves are exhausted, although the <br />ammonium nitrate silos may be moved as the pits progress. See Facilities maps (M13-A) for locations of <br />ammonium nitrate silos. <br />Parking and Storaoe Area <br />Trapper Mine currently has parking spaces for approximately 200 employee and visitor vehicles near the <br />office. These parking areas were surfaced with asphalt approximately September, 1976, and resurtaced <br />in 1991. Equipment parking near the ShoplWarehouse is serviced by a start-up line with air and electric <br />outlets built approximately August, 1979, The outside storage yard contains culverts, fencing, gravel, <br />tires, and other parts and supplies not suitable for storage in the Warehouse. The drainage from the <br />parking lot flows into No-Name above the #5 Dam and the storage areas drain into the industrial waste <br />control facilities. <br />3-183 <br />A~'~tOQiED SFP 2 5 ?001 <br />MR-~eCo <br />
