(iv) It is a mixture of solid waste and one
or more hazardous wastes listed in
335-14-2-.04 and has not been
excluded from
335-14-2-.01(3)(a)2.
under 40 CFR
260.20 and
335-14-1-.03(2),
335-14-2-.01(3)(g),
or
335-14-2-.01(3)(h);
however, the following mixtures of solid wastes and hazardous wastes listed in
335-14-2-.04 are not hazardous
wastes (except by application of
335-14-2-.01(3)(a)2.(i) or
(a)2.(ii)) if the generator can demonstrate
that the mixture consists of wastewater, the discharge of which is subject to
regulation under either Section 402 or Section 307(b) of the Clean Water
Act
(including wastewater at generators which have eliminated the discharge of
wastewater), and:
(I) One or more of the
following spent solvents listed in
335-14-2-.04(2)
- benzene, carbon tetrachloride, tetrachloroethylene, trichloroethylene or the
scrubber waters derived-from the combustion of these spent solvents - provided
that the maximum total weekly usage of these solvents (other than the amounts
that can be demonstrated not to be discharged to wastewater) divided by the
average weekly flow of wastewater into the headworks of the facility's
wastewater treatment or pretreatment system does not exceed one part per
million or the total measured concentration of these solvents entering the
headworks of the facility's wastewater treatment system (at facilities subject
to regulation under the Clean Air
Act, as amended, at 40 CFR parts
60,
61, or
63, or at facilities subject to an enforceable limit in a federal operating
permit that minimizes
fugitive emissions), does not exceed 1 part per million
on an average weekly basis. Any facility that uses benzene as a
solvent and
claims this
exemption must use an aerated biological wastewater treatment
system and must use only lined surface impoundments or tanks prior to secondary
clarification in the wastewater treatment system. Facilities that choose to
measure concentration levels must file a copy of their sampling and analysis
plan with the
State Director ("
Director" as defined in
335-14-1-.02). A facility must
file a copy of a revised sampling and analysis plan only if the initial plan is
rendered inaccurate by
changes in the facility's operations. The sampling and
analysis plan must include the monitoring point location (headworks), the
sampling frequency and methodology, and a list of constituents to be monitored.
A facility is eligible for the direct monitoring option once they receive
confirmation that the sampling and analysis plan has been received by the
Director. The
Director may reject the sampling and analysis plan if he/she
finds that, the sampling and analysis plan fails to include the above
information; or the plan parameters would not enable the facility to calculate
the weekly average concentration of these chemicals accurately. If the
Director
rejects the sampling and analysis plan or if the
Director finds that the
facility is not following the sampling and analysis plan, the
Director shall
notify the facility to cease the use of the direct monitoring option until such
time as the bases for rejection are corrected; or
(II) One or more of the following spent
solvents listed in
335-14-2-.04(2)
-methylene chloride, 1,1,1-trichloroethane, chlorobenzene, o-dichlorobenzene,
cresols, cresylic acid, nitrobenzene, toluene, methyl ethyl ketone, carbon
disulfide, isobutanol, pyridine, spent chlorofluorocarbon solvents,
2-ethoxyethanol, or the scrubber waters derived-from the combustion of these
spent solvents - provided that the maximum total weekly usage of these solvents
(other than the amounts that can be demonstrated not to be discharged to
wastewater) divided by the average weekly flow of wastewater into the headworks
of the facility's wastewater treatment or pretreatment system does not exceed
25 parts per million or the total measured concentration of these solvents
entering the headworks of the facility's wastewater treatment system (at
facilities subject to regulation under the Clean Air
Act as amended, at 40 CFR
parts
60,
61, or
63, or at facilities subject to an enforceable limit in a
federal operating
permit that minimizes
fugitive emissions), does not exceed 25
parts per million on an average weekly basis. Facilities that choose to measure
concentration levels must file a copy of their sampling and analysis plan with
the
State Director, ("
Director" as defined in
335-14-1-.02). A facility must
file a copy of a revised sampling and analysis plan only if the initial plan is
rendered inaccurate by
changes in the facility's operations. The sampling and
analysis plan must include the monitoring point location (headworks), the
sampling frequency and methodology, and a list of constituents to be monitored.

Director shall
notify the facility to cease the use of the direct monitoring option until such
time as the bases for rejection are corrected; or
(III) One of the following wastes listed in
335-14-2-.04(3),
provided that the wastes are discharged to the refinery oil recovery sewer
before primary oil/water/solids separation -heat exchanger bundle cleaning
sludge from the petroleum refining industry (EPA Hazardous Waste Number K050),
crude oil storage tank sediment from petroleum refining operations (EPA
Hazardous Waste Number K169), clarified slurry oil tank sediment and/or in-line
filter/separation solids from petroleum refining operations (EPA Hazardous
Waste Number K170), spent hydrotreating catalyst (EPA Hazardous Waste Number
K171), and spent hydrorefining catalyst (EPA Hazardous Waste Number K172);
or
(IV) A discarded hazardous
waste, commercial chemical product, or chemical intermediate listed in
335-14-2-.04(2) through
(4), arising from de minimis losses of these
materials. For purposes of
335-14-2-.04, "deminimis" losses
are inadvertent releases to a wastewater treatment system, including those from
normal material handling operations (e.g. spills from the unloading or transfer
of materials from bins or other containers, leaks from pipes, valves or other
devices used to transfer materials); minor leaks of
process equipment, storage
tanks or containers; leaks from well maintained pump packings and seals; sample
purgings; relief device discharges, discharges from safety showers and rinsing
and cleaning of personal safety equipment; and rinsate from empty containers or
from containers that are rendered empty by that rinsing. Any manufacturing
facility that claims an
exemption for de minimis quantities of wastes listed in
335-14-2-.04(2) through
(3), or any nonmanufacturing facility that
claims an
exemption for de minimis quantities of wastes listed in
335-14-2-.04 must either have
eliminated the discharge of wastewaters or have included in its Clean Water
Act
permit application or submission to its pretreatment control authority the
constituents for which each waste was listed (335-14-2-Appendix VII); and the
constituents in the table "Treatment Standards for Hazardous Wastes" in
335-14-9-.04(1)
for which each waste has a treatment standard (i.e., Land Disposal Restriction
constituents). A facility is eligible to claim the
exemption once the
permit
writer or control authority has been notified of possible de minimis releases
via the Clean Water
Act permit application or the pretreatment control
authority submission. A copy of the Clean Water
permit application or the
submission to the pretreatment control authority must be placed in the
facility's on-site files; or
(V)
Wastewater resulting from laboratory operations containing toxic (T) wastes
listed in
335-14-2-.04, provided that the
annualized average flow of laboratory wastewater does not exceed one percent of
total wastewater flow into the headworks of the facility's wastewater treatment
or pretreatment system, or provided the wastes combined annualized average
concentration does not exceed one part per million in the headworks of the
facility's wastewater treatment or pretreatment facility. Toxic (T) wastes used
in laboratories that are demonstrated not to be discharged to wastewater are
not to be included in this calculation; or
(VI) One or more of the following wastes
listed in
335-14-2-.04(3)
- wastewaters from the production of carbamates and carbamoyl oximes (EPA
Hazardous Waste No. K157) - provided that the maximum weekly usage of
formaldehyde, methyl chloride, methylene chloride, and triethylamine (including
all amounts that cannot be demonstrated to be reacted in the
process, destroyed
through treatment, or is recovered, i.e., what is discharged or volatilized)
divided by the average weekly flow of
process wastewater prior to any dilution
into the headworks of the facility's wastewater treatment system does not
exceed a total of 5 parts per million by weight or the total measured
concentration of these chemicals entering the headworks of the facility's
wastewater treatment system (at facilities subject to regulation under the
Clean Air
Act as amended, at 40 CFR parts
60,
61, or
63, or at facilities
subject to an enforceable limit in a federal operating
permit that minimizes
fugitive emissions), does not exceed 5 parts per million on an average weekly
basis. Facilities that choose to measure concentration levels must file a copy
of their sampling and analysis plan with the
State Director ("
Director" as
defined in

Director finds that the
facility is not following the sampling and analysis plan, the
Director shall
notify the facility to cease the use of the direct monitoring option until such
time as the bases for rejection are corrected; or
(VII) Wastewaters derived from the treatment
of one of more of the following wastes listed in
335-14-2-.04(3)

solvents, filtrates, and decantates) from the production of carbamates and
carbamoyl oximes (EPA Hazardous Waste No. K156) - provided, that the maximum
concentration of formaldehyde, methyl chloride, methylene chloride, and
triethylamine prior to any dilutions into the headworks of the facility's
wastewater treatment system does not exceed a total of 5 milligrams per liter
or the total measured concentration of these chemicals entering the headworks
of the facility's wastewater treatment system (at facilities subject to
regulation under the Clean Air
Act as amended, at 40 CFR parts
60,
61, or
63,
or at facilities subject to an enforceable limit in a federal operating
permit
that minimizes
fugitive emissions), does not exceed 5 milligrams per liter on
an average weekly basis. Facilities that choose to measure concentration levels
must file a copy of their sampling and analysis plan with the
State Director
("
Director" as defined in 40
