Editing Toxicity characteristic leaching procedure (section)

==Application of test==
The Environmental Compliance Supervisor at a typical municipal [[landfill]] (as defined by RCRA [[Resource Conservation and Recovery Act#Subtitle D: Non-hazardous Solid Wastes|Subtitle D]]) uses TCLP data to determine whether a waste may be accepted into the facility. If TCLP analytical results are below the TCLP D-list maximum contamination levels (MCLs) the waste can be accepted. If they are above these levels the waste must be taken to a [[Hazardous_waste#Disposal|hazardous waste disposal facility]] and the cost of disposal may increase from about $50.00/ton to as much as $1200.00/ton.

As extremely contaminated material is expensive to dispose of, grading is necessary to ensure safe disposal and to avoid paying for disposal of "clean fill."  The TCLP procedure is generally useful for classifying waste material for disposal options.  

Spent abrasive or soil from a construction site usually needs to have a TCLP for lead done to determine where the waste goes next.
