40 CFR §261.24, outlines the 40 contaminants the TCLP analysis tests for (See Table 1—Maximum Concentration of Contaminants for Toxicity
Characteristic). If a “Solid Waste” fails the test for one or more of these compounds, the waste is considered to be a characteristic hazardous
waste – unless there is an exemption that applies. Bear in mind, too, that a characteristic waste may still also be a “listed” hazardous waste.
