Interlake is located on the east and west side of S. Sacramento St. in Lodi and manufactures metal storage products including cantilever racks and palette racks. The manufacturing process includes fabrication, preparation, and painting of the racks. A maintenance department is operated to service the lifts and machinery used in the manufacturing process. Residential housing borders the north, south, and west sides of the Interlake property and industrial buildings are to the east. This facility operates on two shifts and employs 179 people. Interlake has been operating at the site since 1967. A "roll form" coolant is used on the steel coiled strips during the fabrication of the metal storage products. This roll form coolant becomes contaminated with mill scale and machine grindings. Absorbent is used to clean up any roll form coolant that spills onto the floor in the roll form area. These two wastestreams in 1991 were characterized as "Non RCRA Hazardous Waste Solid (181)". In 1991, 31.3 tons of this waste was manifested off-site by American Environmental, 11855 White Rock Rd., Rancho Cordova, CA. In 1992, 16.1 tons were hauled off-site by Chemical Waste Management, Old Skyline Blvd., Kettleman Hills, CA 93239. Before the cantilevers and palette racks are painted, they are washed with an aqueous solution. The rinsate generated is collected in an aboveground tank where the solids settle out from the liquid. The solids are referred to as a sludge that is managed as a hazardous waste, and the liquid is discharged to the city of Lodi P.O.T.W. (Permit #145 "Dump Wash Tank", valid through January 27, 1994). In 1991, the sludge was described as "Non RCRA Hazardous Waste Liquid (135)". American Environmental, 11855 White Rock Rd., Rancho Cordova, CA, hauled 16.5 tons of this waste off-site. In 1992, this waste stream was redescribed as "Non Hazardous Waste Liquid, Wash Tank". The painting operation generates two wastestreams that are managed as a hazardous waste. A MEK/paint waste is generated from cleaning the hand held spray guns with MEK. The MEK/paint waste is then recycled on-site through a solvent distillation unit to recover the MEK. The unrecoverable MEK is referred to as " MEK still bottoms". In 1991, 13.0 tons of still bottoms were manifested off site by Rineco Chemical Industries, 1007 Vulcan Rd., Haskell Benton, AR, 72015. The other paint waste is generated from paint over spray, used paint filters and paper used in the painting process. In 1992, 1.9 tons of this paint waste was hauled off-site by Chemical Waste Management, Old Skyline Blvd., Kettleman Hills, CA 93239. Il
