A.
					 Applicability. You must comply with LDRs prior to placing soil that exhibits a
					 characteristic of hazardous waste, or exhibited a characteristic of hazardous
					 waste at the time it was generated, into a land disposal unit. The following
					 chart describes whether you must comply with LDRs prior to placing soil
					 contaminated by listed hazardous waste into a land disposal unit.

*To determine the date any given listed
								  hazardous waste contaminated any given volume of soil, use the last date any
								  given listed hazardous waste was placed into any given land disposal unit or,
								  in the case of an accidental spill, the date of the spill.
B. Prior to land disposal, contaminated soil
					 identified by Subsection A of this Section as needing to comply with LDRs must
					 be treated according to the applicable treatment standards specified in
					 Subsection C of this Section or according to the universal treatment standards
					 specified in LAC 33:V.2233 applicable to the contaminating listed hazardous
					 waste and/or the applicable characteristic of hazardous waste if the soil is
					 characteristic. The treatment standards specified in Subsection C of this
					 Section and the universal treatment standards may be modified through a
					 treatment variance approved in accordance with LAC 33:V.2233.
C. Treatment Standards for Contaminated
					 Soils. Prior to land disposal, contaminated soil identified by Subsection A of
					 this Section as needing to comply with LDRs must be treated according to all
					 the standards specified in this Subsection or according to the universal
					 treatment standards specified in LAC 33:V.2233.
1. All Soils. Prior to land disposal, all
					 constituents subject to treatment must be treated as follows.
a. For nonmetals except carbon disulfide,
					 cyclohexanone, and methanol, treatment must achieve 90 percent reduction in
					 total constituent concentrations, except as provided by Subparagraph C.1.c of
					 this Section.
b. For metals and
					 carbon disulfide, cyclohexanone, and methanol, treatment must achieve 90
					 percent reduction in constituent concentrations as measured in leachate from
					 the treated media (tested according to the toxicity characteristic leaching
					 procedure, TCLP) or 90 percent reduction in total constituent concentrations
					 (when a metal removal treatment technology is used), except as provided by
					 Subparagraph C.1.c of this Section.
c. When treatment of any constituent subject
					 to treatment to a 90 percent reduction standard would result in a concentration
					 less than 10 times the universal treatment standard for that constituent,
					 treatment to achieve constituent concentrations less than 10 times the
					 universal treatment standard is not required. Universal treatment standards are
					 identified in LAC 33:V.2299.Appendix, Table 7.
