4.3 Management <br />Used oil means any oil that has been refined from crude oil, or any synthetic oil, that <br />has been used, and, as a result of use or as a consequence of extended storage, or <br />spillage, has been contaminated with physical or chemical impurities. Examples of used <br />oil are: <br />o spent lubricating fluids which have been removed from an engine crankcase, <br />transmission, gearbox, or differential of an automobile, bus, truck, vessel, plane, <br />heavy equipment, or machinery powered by an internal combustion enigne; <br />o industrial oils, including compressor, turbine, and bearing oil; <br />o hydraulic oil; <br />o metal -working oil; <br />o refrigeration oil; and <br />o railroad drainings. <br />Used oil must be managed as hazardous waste unless it can be shown that the <br />contaminants below do not exceed the indicated limits, the oil is not hazardous by any <br />other characteristics, and the oil is not mixed with any federally listed hazardous waste: <br />Total arsenic: 5 mg/kg or less <br />Total cadmium: 2 mg/kg or less <br />Total chromium: 10 mg/kg or less <br />Total halogens: 3000 mg/kg or less (however, used oil containing greater than <br />1000 mg/kg total halogens is presumed to be mixed with a <br />federally listed waste, and is thus a hazardous waste, unless it <br />can be demonstrated that the oil does not contain more than <br />1000 mg/kg total halogens listed in Appendix VIII of Part <br />261, Title 40, Code of Federal Regulations) <br />Total lead: 50 mg/kg or less <br />Total .PCBs: 2 mg/kg or less <br />Flashpoint: Minimum Standards by ASTM <br />Compressor oil extracted from refrigeration and air conditioning equipment is typically <br />mixed with refrigerant during equipment operation. In the case of a refrigerator or <br />freezer which typically uses CFC -12 as the refrigerant, the compressor oil will be mixed <br />with chlorinated fluorocarbons which are halogenated compounds. <br />Used oil containing more than 1000 mg/kg total halogens is presumed to be mixed with <br />17 <br />
