. For purposes of this article, the following definitions
apply:
(a) "Agricultural drainage water" means subsurface water or
perched groundwater which is drained from beneath agricultural lands
and which results from agricultural irrigation.
(b) "Free liquids" mean liquids which readily separate from the
solid portion of a hazardous waste under ambient temperature and
pressure.
(c) "Hazardous waste landfill" means a disposal facility, or part
of a facility, where hazardous waste is placed in or onto land and
which is not a land treatment facility, a surface impoundment, or an
injection well.
(d) "Land disposal" means placement in or on the land, and
includes, but is not limited to, placement in a landfill, surface
impoundment, waste pile, injection well, land treatment facility,
salt dome formation, salt bed formation, underground mine or cave, or
concrete vault or bunker intended for disposal purposes.
(e) Notwithstanding Section 25123.5, and for purposes of this
article only, "treatment" means any method, technique, or process,
including incineration, occurring at authorized facilities that
changes the physical, chemical, or biological character or
composition of any hazardous waste and, by that change, the waste
becomes nonhazardous, significantly less hazardous, or more suitable
for land disposal because of removal or substantial reduction of
undesirable properties, such as toxicity, mobility, persistence,
reactivity, bioaccumulation, flammability, or corrosivity. "Treatment"
does not include any of the following, to the extent that one or
more of the following are the only methods which are used:
(1) Solidification of hazardous waste by the addition of absorbent
material that produces a change only in the physical character of
the waste, without a corresponding change in the chemical character
of the waste.
(2) Treatment occurring directly in or on the land, such as land
treatment, except that treatment may include in situ treatment
necessary for site mitigation.
(3) Dilution of hazardous waste by the addition of nonhazardous
material.
(4) Evaporation in a surface impoundment.
(f) "Treated hazardous waste" means a hazardous waste that has
been subject to treatment, as specified in subdivision (e), that
meets treatment standards established by the department pursuant to
Section 25179.6, and applicable treatment standards adopted by the
Environmental Protection Agency pursuant to Section 3004(m) of the
federal act (42 U.S.C. Sec. 6924(m)). "Treated hazardous waste" also
includes a hazardous waste that meets all applicable treatment
standards without prior treatment.
(g) "Designated treatment technology" means a hazardous waste
environmental technology certified by the department in accordance
with Section 25200.1.5 that the department has also designated,
pursuant to Section 25179.7, as a method which will treat specified
types of hazardous waste to substantially reduce or eliminate the
risk to human health and the environment posed by that waste.
(h) "Treatable waste" means a type or category of hazardous waste,
specified by the department, for which there is a designated
treatment technology. A waste becomes a treatable waste one year
after designation of the first treatment technology found by the
department to be suitable for treatment of that type or category of
hazardous waste pursuant to Section 25179.7.
