Liquids can be tested using any method as
long as it has documented quality control
By definition, liquids contain less than 0.5%
solids
Solids must go through a procedure that
mimics landfill conditions called a Toxic
Characteristic Leaching Procedure
(TCLP) prior to testing.

20th California Unified Program Annual Training ConferenceFebruary 2018
Promulgated in 1990 replacing the old EP (Extraction Procedure) Toxicity test
Solid/liquid samples are separated, the solids are processed and then re-combined with the liquid portion for analysis.
Uses acetic acid for a leaching agent
20 parts acid to 1 part sample
Put into a tumbler for 18 hours
Then filtered and the leachate is analyzed (solids are discarded)

the State Government allow for
recycled scrap metal to be excluded
from hazardous waste requirements.
The definition for the exemption is not
the same
The State’s exclusions are more
stringent than the Feds.

Always run the TTLC first (test name
is a CAM-17)
The test is inexpensive and gives
valuable information for both RCRA
and CA
See if results are > TTLC levels, if yes
it is at least a CA Haz Waste

If the results of the STLC are below
the numbers listed in Table II, then
the waste is not a hazardous waste
for toxicity per CCR 66261.23(a)(1)
and (2).
However, in CA there are still 6
criteria more to go!!!!!!
