Show In addition to the large pieces of equipment listed above, Kennecott has an inventory of the equipment associated with the entire facility. Kennecott will sell equipment and salvageable materials from the facilities before and(or) during demolition. C.3.3 Refinery Area The Kennecott Refinery is a 45-acre industrial facility located on the north end of the Oquirrh Mountains between the Smelter and the Arthur Site. The existing facility was built by Kennecott in 1950 to refine copper anodes from the smelter and produce electrochemically pure copper, gold, and silver. The copper refining process is housed in the Tankhouse, which covers approximately 224,000 square feet. The Refinery has been modernized to match the capacity of the modernized Smelter. The footprint of the Tankhouse was not increased. Processes associated with precious metals recovery are housed in a new building to the west of the Tankhouse. The Refinery is comprised of the Tankhouse, MPC Building, Silver Building, Lead Shop, Electrolyte Purification (EP) Building, Boiler Plant, Chemical Laboratory, and other maintenance and administrative structures. The Refinery produces copper cathodes, gold bars, silver bars, platinum sponge, palladium sponge and commercial grade selenium. Most of the structures were built in the early 1950's and have remained virtually unchanged. The Tankhouse accommodated the cells where the anode is electrically plated to a starter sheet to become the commercial cathode. Slimes washed from the cell bottom are delivered to the Silver Building. Electrolyte used in the process was mixed and cleaned in the now obsolete EP Building. C.3 .3 .1 Refinery Area Soils The Refinery Area (Dwg. No. 503-T-0173) consists of seven soil sites. Only three of the seven sites have been characterized to date. Characterization sampling indicates two of the three sites are elevated in metals. The Precious Metals Site (R0l) is the original Silver Building footprint. The building is scheduled for demolition in the summer of 1996 with soils characterization sampling to follow. The Old Spent Electrolyte Pond Site (R02) is a capped and vegetated pond which received spent electrolyte solutions. Characterization sampling indicates five of the twenty-three samples are elevated in total arsenic (360 ppm, 450 ppm, 513 ppm, 241 ppm and 394 ppm) and(or) total lead (9935 ppm) and(or) total selenium (1800 ppm, 7332 ppm, 2215 ppm and 1844 ppm). The Sites' overall average, maximum and minimum are listed below. Appendix C* 12 July 18, 1996 Rev. C |
