Phase I was agreement with the U.S. Department of : 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 field lysinieters 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. ;1 t t. iv '*. : '"'lUi 'x<>- -... ,ri r
