Procedure 90109-0
1.1 The TC4P is designed to determine the mobility of both organic and inorganic
contaminates present in liquid, solid, and multiphasic wastes.
1.2 If a total analysis of the waste demonstrates that individual contaminates are not present
in the waste, or that they are present but at such low concentrations that the appropriate
regulatory thresholds could not possibly be exceeded, the TCLP need not be run.
Us SUMMARY OF METHOD
3.0
21 For liquid wastes ( i.e, those containing insignificant solid material), the waste, after
filtration through a 0.6-0.8 an glass fiber filter, is defined as the TCLP extract.
2.2 For wastes comprised of solids or for wastes containing significant amounts of solid
material, the particle-size of the waste is reduced (if necessary); the liquid phase, if any,
is separated from the solid phase and stored for later analysis. The solid phase is
extraeted with an amount of extraction fluid equal to twenty (20) times the weight of the
solid phase. The extraction fluid employed is a function of alkalinity of the solid phase of
the waste. A special extractor vessel is used when testing for volatiles (Reference Table
1, Page 17). Following extraction, the liquid extract is separated from the solid phase by
0.6 to 0.8 µtn glass fiber filter filtration.
2.3 If compatible (i.e., multiple phases will not form on combination), the initial liquid phase
of the waste is added to the liquid extract, and these liquids are analyzed together. If
incompatible, the liquids are analyzed separately and the results are mathematically
combined to yield a volume-weighted average connection.

An aeceptable agitation apparatus is one which is capable of routing the extraction vessel
in an end-over-end fashion (Reference Table 2, Page 18) at thirty (30) s two (2) rpm.
Suitable devices known to EPA are identified in Table 2.
