Title: Mercury-containing Lamps and EPA’s Toxicity Characteristic Leaching Procedure (TCLP)

URL: http://www.informinc.org/fs_P3tclp.pdf

Abstract: This fact sheet from INFORM, Inc. explains the U.S. EPA’s Toxicity Characteristic Leaching Procedure (TCLP). The U.S. EPA has identified 40 toxic chemicals that can cause harm when products containing them are disposed of in landfills and the chemicals leach out. In order to determine the potential of specific wastes in a landfill to leach dangerous concentrations of toxic chemicals into groundwater, the EPA developed a protocol known as the toxicity characteristic leaching procedure (TCLP). Products containing one or more of the listed toxins are assessed using the TCLP to estimate how much of their toxic contents would be released into landfill leachate under ordinary conditions. If the amount of a particular chemical released under test conditions exceeds regulatory limits, the waste qualifies as hazardous and must be handled according to regulations governing hazardous waste. Products that do not leach toxic materials at levels exceeding regulatory limits are termed TCLP-compliant. This fact sheet discusses the limitations of the TCLP, particularly in regards to mercury-containing lamps, and issues related to appropriate disposal of mercury-containing lamps.
