Section 128-20c-013 - Alternative LDR treatment standards for contaminated soil013.01 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 |
Didn't 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 |
Didn't 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 | Needn't comply with the LDRs |
Didn't apply to the listed waste when it contaminated the soil* | Don't apply to the listed waste now | - | Needn't comply with the LDRs |
*For dates of LDR applicability, see 40 CFR Part 268 Appendix VII. 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.
013.02 Prior to land disposal, contaminated soil identified by paragraph 013.01 of this section as needing to comply with LDRs must be treated according to the applicable treatment standards specified in paragraph 013.03 of this section or according to the Universal Treatment Standards specified in Section 012 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 paragraph 013.03 of this section and the Universal Treatment Standards may be modified through a treatment variance approved in accordance with Chapter 5, 006.013.03 Treatment standards for contaminated soils Prior to land disposal, contaminated soil identified by paragraph 013.01 of this section as needing to comply with LDRs must be treated according to all the standards specified in this paragraph or according to the Universal Treatment Standards specified in Section 012.
013.03A All soils. Prior to land disposal, all constituents subject to treatment must be treated as follows: 013.03A1 For non-metals except carbon disulfide, cyclohexanone, and methanol, treatment must achieve 90 percent reduction in total constituent concentrations, except as provided by paragraph 013.03A3 of this section.013.03A2 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 TCLP) or 90 percent reduction in total constituent concentrations (when a metal removal treatment technology is used), except as provided by paragraph 013.03A3 of this section.013.03A3 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 Section 012, Table 12. 013.03B Soils that exhibit the characteristic of ignitability, corrosivity or reactivity. In addition to the treatment required by paragraph 013.03A of this section, prior to land disposal, soils that exhibit the characteristic of ignitability, corrosivity, or reactivity must be treated to eliminate these characteristics.013.03C Soils that contain nonanalyzable constituents. In addition to the treatment requirements of paragraphs 013.03A and 013.03B of this section, prior to land disposal, the following treatment is required for soils that contain nonanalyzable constituents: 013.03C1 For soil that contains only analyzable and nonanalyzable organic constituents, treatment of the analyzable constituents to the levels specified in paragraphs 013.03A and 013.03B of this section; or,013.03C2 For soil that contains only nonanalyzable constituents, treatment by the method(s) specified in Section 010 for the waste contained in the soil.013.04 Constituents subject to treatment When applying the soil treatment standards in paragraph 013.03 of this section, constituents subject to treatment are any constituents listed in Section 012, Table 12, Universal Treatment Standards that are reasonably expected to be present in any given volume of contaminated soil, except fluoride, selenium, sulfides, vanadium, zinc, and are present at concentrations greater than ten times the universal treatment standard. PCBs are not a constituent subject to treatment in any given volume of soil which exhibits the toxicity characteristic solely because of the presence of metals.
013.05 Management of treatment residuals Treatment residuals from treating contaminated soil identified by paragraph 013.01 of this section as needing to comply with LDRs must be managed as follows:
013.05A Soil residuals are subject to treatment standards of this section;013.05B Non-soil residuals are subject to: 013.05B1 For soils contaminated by a listed hazardous waste, the RCRA Subtitle C standards applicable to the listed hazardous waste; and013.05B2 For soils that exhibit a characteristic of hazardous waste, if the non-soil residual also exhibits a characteristic of hazardous waste, the treatment standards applicable to the characteristic hazardous waste.128 Neb.
