South Carolina Code of Regulations › Chapter 61 - DEPARTMENT OF HEALTH AND ENVIRONMENTAL CONTROL › Subchapter 61-79 - Hazardous Waste Management Regulations › Part 61-79.268 - LAND DISPOSAL RESTRICTIONS › Subpart D - TREATMENT STANDARDS › Section 61-79.268.D.49 - Alternative LDR treatment standards for contaminated soil

Current through Register Vol. 48, No. 6, June 28, 2024
(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 [FN*]
apply to the listed waste now
must comply with LDRs
Didn't apply to the listed waste when it
								  contaminated the soil [FN*]
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
[FN*]
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 LDRs
didn't apply to the listed waste when it
								  contaminated the soil
[FN*]
don't apply to the listed waste now
needn't comply with LDRs
[FN*] For dates of LDR applicability, see 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 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 paragraph (a) of this section as needing to comply with LDRs must
				  be treated according to the applicable treatment standards specified in
				  paragraph (c) of this section or according to the Universal Treatment Standards
				  specified in 268.48 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 paragraph (c) of this
				  section and the Universal Treatment Standards may be modified through a
				  treatment variance approved in accordance with 268.44.
(c) Treatment standards for contaminated
				  soils. Prior to land disposal, contaminated soil identified by paragraph (a) 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 268.48.
(1)
				  All soils. Prior to land disposal, all constituents subject to treatment must
				  by treated as follows:
(A) For non-metals
				  except carbon disulfide, cyclohexanone, and methanol, treatment must achieve 90
				  percent reduction in total constituent concentrations, except as provided by
				  paragraph (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 TCLP) or 90 percent reduction in total constituent
				  concentrations (when a metal removal treatment technology is used), except as
				  provided by paragraph (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 268.48 Table UTS.
