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.

If LDRs	And If LDRs	And If	Then You
applied to the listed waste when it contaminated the soil*	apply to the listed waste now	&&&&&&	must comply with LDRs
did not apply to the listed waste when it contaminated the soil*	apply to the listed waste now	the soil is determined to contain the listed waste when the soil is first generated	must comply with LDRs
did not apply to the listed waste when it contaminated the soil*	apply to the listed waste now	the soil is determined not to contain the listed waste when the soil is first generated	need not comply with LDRs
did not apply to the listed waste when it contaminated the soil*	do not apply to the listed waste now	&&&&&&..	need not comply with LDRs
*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.

2. Soils That Exhibit the Characteristic of Ignitability, Corrosivity, or Reactivity. In addition to the treatment required by Paragraph C.1 of this Section, prior to land disposal, soils that exhibit the characteristic of ignitability, corrosivity, or reactivity must be treated to eliminate these characteristics.

3. Soils That Contain Nonanalyzable Constituents. In addition to the treatment requirements of Paragraphs C.1 and 2 of this Section, prior to land disposal, the following treatment is required for soils that contain nonanalyzable constituents:

a. for soil that also contains only analyzable and nonanalyzable organic constituents, treatment of the analyzable organic constituents to the levels specified in Paragraphs C.1 and 2 of this Section; or

b. for soil that contains only nonanalyzable constituents, treatment by the method(s) specified in LAC 33:V.2227 for the waste contained in the soil.

D. Constituents Subject to Treatment. When applying the soil treatment standards in Subsection C of this Section, constituents subject to treatment are any constituents listed in LAC 33:V.2299.Appendix, Table 7 (Universal Treatment Standards) that are reasonably expected to be present in any given volume of contaminated soil, except fluoride, selenium, sulfides, vanadium, and zinc, and that are present at concentrations greater than 10 times the universal treatment standard. PCBs are not a constituent subject to treatment in any given volume of soil that exhibits the toxicity characteristic solely because of the presence of metals.

E. Management of Treatment Residuals. Treatment residuals from treating contaminated soil identified by Subsection A of this Section as needing to comply with LDRs must be managed as follows:

1. soil residuals are subject to the treatment standards of this Section; and

2. nonsoil residuals are subject to:

a. for soils contaminated by listed hazardous waste, the RCRA Subtitle C standards applicable to the listed hazardous waste; and

b. for soils that exhibit a characteristic of hazardous waste, if the nonsoil residual also exhibits a characteristic of hazardous waste, the treatment standards applicable to the characteristic hazardous waste.
