California Code of Regulations › Title 22 - Social Security › Division 4.5 - Environmental Health Standards for the Management of Hazardous Waste › Chapter 18 - Land Disposal Restrictions › Article 4 - Treatment Standards › Section 66268.49 - Alternative LDR Treatment Standards for Contaminated Soil

Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a) Applicability. You shall 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 shall
				  comply with LDRs prior to placing soil contaminated by listed hazardous waste
				  into a land disposal unit:

*For dates of LDR applicability, see CCR, Title 22,
								chapter 18, 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.
(b)
				  Prior to land disposal, contaminated soil identified by subsection (a) of this
				  section as needing to comply with LDRs shall be treated according to the
				  applicable treatment standards specified in subsection (c) of this section or
				  according to the Universal Treatment Standards specified in section
				  66268.48 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 section
				  66268.44.
(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 shall be treated according to
				  all the standards specified in this subsection or according to the Universal
				  Treatment Standards specified in section
				  66268.48.
(1) All soils. Prior to land disposal, all
				  constituents subject to treatment shall be treated as follows:
(A) For non-metals except carbon disulfide,
				  cyclohexanone, and methanol, treatment shall achieve 90 percent reduction in
				  total constituent concentrations, except as provided by subsection (c)(1)(C) of
				  this section.
(B) For metals and
				  carbon disulfide, cyclohexanone, and methanol, treatment shall 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 subsection (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 section
				  66268.48 Table
				  UTS.
