meet the definition of"hazardous waste." This determination may be performed by <br /> either testing representative samples of routine, predictable (and in some cases <br /> periodic) waste streams. Alternatively, the hazardous waste determination can be made <br /> by using knowledge of the chemicals and processes involved. <br /> To determine if a waste is hazardous, perform the following steps: <br /> • Determine whether the waste is excluded from regulation under 22 CCR § <br /> 66261.4. In most cases, these exclusions will not apply to waste water and <br /> drinking water operations. <br /> • If the waste is not excluded from regulation, determine whether the waste is <br /> listed as a hazardous waste in 22 CCR §66261 subpart D (federally-listed <br /> waste), or in 22 CCR § 66261.126 Appendix X (California regulated hazardous <br /> waste). A listed waste may include used oil, unused commercial chemical or <br /> off-specification product, and a spent solvent used for degreasing. <br /> • If the waste is not listed as a hazardous waste, determine whether it exhibits a <br /> hazardous characteristic (i.e., ignitable, corrosive, reactive, or toxic) by using <br /> knowledge of the waste or performing one of the following tests using a <br /> California state-certified environmental testing laboratory. It is often helpful <br /> to review of the Material Safety Data Sheet (SDS) to determine the hazardous <br /> characteristics of a hazardous material that later becomes a hazardous waste. <br /> A description of the waste characteristics is provided below. <br /> Ignitability <br /> A waste is ignitable if a representative sample is easily combustible or flammable or if <br /> burnt it bums so vigorously that it creates a hazard. A waste is ignitable if it is: <br /> • A liquid, other than an aqueous solution containing less than 24 percent <br /> alcohol by volume, with a flash point of less than 140 degrees Fahrenheit (°F). <br /> • A non-liquid capable under standard temperature of causing fire by means of <br /> friction, absorption or moisture, or spontaneous chemical changes and which <br /> when ignited burns so vigorously and persistently that it creates a hazard. <br /> • An ignitable compressed gas as defined in the Department of Transportation <br /> (DOT) regulations. <br /> • An oxidizer as defined in DOT regulations. <br /> An ignitable waste is assigned the EPA Hazardous Waste <br /> Number D001 <br /> 2of13 <br />
