D. Development and Evaluation of the >
TCLP
.............. .....
1. Introduction
This Section provides detailed
information on how the TCLP was
. developed and evaluated. Still more
.detailed information regarding the TCLP
. is available in a Background Document
that F.PA has prepared for the TCLP
(Ref. 33). .
.....
2. Experimental Design
'
EPA, through an interagency agreement with the U.S. Department of
"- -
.;
_
Energy's Oak Ridge National Laboratory
(ORNL), has conducted a research <
program designed to develop an . -V*'
improved leaching test, the TCLP. The
TCLP development program was split up
into three phases. Phases I and II. and
part of Phase III have been completed.
Phase I consisted of an initial data'
. gathering effort in which a number of
wastes were leached with a leachate
derived from municipal refuse. The
wastes were also extracted with a . -; i,
variety of laboratory leaching media .
and contact procedures. Phase I was
designed to narrow the universe of .
potential candidate leaching procedures.
In Phase II, additional wastes were
leached and the candidate procedures refined into the draft TCLP. During this phase of testing, public assistance and review of the draft was solicited. ' '
The overall approach employed in Phase I was as follows: ^
a. Large-scale Held lysimeters were'
filled with domestic and commercial
refuse and used to generate a municipal
waste leachate (MWL).
.
b. The MWL was used to leach four .
industrial solid wastes in large columns.
