(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.
(2) Soils that
exhibit the characteristic of ignitability, corrosivity or reactivity. In
addition to the treatment required by subsection (c)(1) of this section, prior
to land disposal, soils that exhibit the characteristic of ignitability,
corrosivity, or reactivity shall be treated to eliminate these
characteristics.
(3) Soils that
contain nonanalyzable constituents. In addition to the
treatment requirements
of subsections (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 contains only
analyzable and nonanalyzable organic constituents, treatment of the analyzable
organic constituents to the levels specified in subsections (c)(1) and (2) of
this section; or,
(B) For
soil that
contains only nonanalyzable constituents,
treatment by the method(s) specified
in section
66268.42 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 section
66268.48 Table UTS--Universal
Treatment Standards that are reasonably expected to be present in any given
volume of contaminated
soil, except fluoride, selenium, sulfides, vanadium,
zinc, and that are present at concentrations greater than ten times the
universal
treatment standard. PCBs are not constituents subject to
treatment in
any given volume of
soil which 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 shall be managed as follows:
(1) Soil residuals are subject to the
treatment standards of this section;
(2) Non-
soil residuals are subject to:
(A) For soils contaminated by listed
hazardous waste, the hazardous waste standards applicable to the listed
hazardous waste; and
(B) 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.
