Hazardous Waste Determination
 
 
National Summary
Generators must determine whether generated material is first, a "waste," second, a "solid waste," and last, a "hazardous waste." There are two methods of making a determination of hazardous waste. The substance may be a "listed" waste, one of hundreds of substances that EPA has placed on a list of hazardous waste. Or the substance may be a "characteristic" waste. A characteristic waste is one that exhibits any of four hazardous waste characteristics: corrosivity, ignitability, reactivity, or toxicity.
