A test for determining whether or not debris is hazardous based on an analysis of leachable
material by either atomic absorption spectroscopy or inductively coupled plasma atomic emission
spectroscopy. Procedures for conducting the test are found in Appendix II of 40 CFR 261,
“Identification and Listing of Hazardous Waste.” Prior to 1991, the EP Toxicity Test was used.
Presently, the toxicity characteristic leaching procedure (TCLP) test is used.
