c) A tank, surface
impoundment, or container is exempt from standards specified in Sections
724.984 through
724.987, as applicable, provided that all hazardous waste placed in the waste
management unit is one of the following:
1) A
tank, surface impoundment, or container for which all hazardous waste entering
the unit has an average VO concentration at the point of waste origination of
less than 500 parts per million by weight (ppmw). The average VO concentration
must be determined by the procedures specified in Section
724.983(a).
The owner or operator must review and update, as necessary, this determination
at least once every 12 months following the date of the initial determination
for the hazardous waste streams entering the unit.
2) A tank, surface impoundment, or container
for which the organic content of all the hazardous waste entering the waste
management unit has been reduced by an organic destruction or removal process
that achieves any one of the following conditions:
A) The process removes or destroys the
organics contained in the hazardous waste to a level such that the average VO
concentration of the hazardous waste at the point of waste treatment is less
than the exit concentration limit (Ct) established for
the process. The average VO concentration of the hazardous waste at the point
of waste treatment and the exit concentration limit for the process must be
determined using the procedures specified in Section
724.983(b).
B) The process removes or destroys the
organics contained in the hazardous waste to a level such that the organic
reduction efficiency (R) for the process is equal to or greater than 95
percent, and the average VO concentration of the hazardous waste at the point
of waste treatment is less than 100 ppmw. The organic reduction efficiency for
the process and the average VO concentration of the hazardous waste at the
point of waste treatment must be determined using the procedures specified in
Section
724.983(b).
C) The process removes or destroys the
organics contained in the hazardous waste to such a level that the actual
organic mass removal rate (MR) for the process is equal to or greater than the
required organic mass removal rate (RMR) established for the process. The
required organic mass removal rate and the actual organic mass removal rate for
the process must be determined using the procedures specified in Section
724.983(b).
D) The process is a biological process that
destroys or degrades the organics contained in the hazardous waste so that
either of the following conditions are met:
i) The organic reduction efficiency (R) for
the process is equal to or greater than 95 percent, and the organic
biodegradation efficiency (Rbio) for the process is
equal to or greater than 95 percent. The organic reduction efficiency and the
organic biodegradation efficiency for the process must be determined using the
procedures specified in Section
724.983(b).
ii) The total actual organic mass
biodegradation rate (MRbio) for all hazardous waste
treated by the process is equal to or greater than the required organic mass
removal rate (RMR). The required organic mass removal rate and the actual
organic mass biodegradation rate for the process must be determined using the
procedures specified in Section
724.983(b).
E) The process removes or destroys
the organics contained in the hazardous waste and meets all of the following
conditions:
i) From the point of waste
origination through the point where the hazardous waste enters the treatment
process, the hazardous waste is continuously managed in waste management units
that use air emission controls in accordance with the standards specified in
Sections
724.984 through
724.987, as applicable to the waste management unit.
ii) From the point of waste origination
through the point where the hazardous waste enters the treatment process, any
transfer of the hazardous waste is accomplished through continuous hard-piping
or other closed system transfer that does not allow exposure of the waste to
the atmosphere.
BOARD NOTE: The USEPA considers a drain system that meets the
requirements of federal subpart RR of
40 CFR
63(National Emission
Standards for Individual Drain Systems) to be a closed system.
iii) The average VO concentration of the
hazardous waste at the point of waste treatment is less than the lowest average
VO concentration at the point of waste origination, determined for each of the
individual hazardous waste streams entering the process or 500 ppmw, whichever
value is lower. The average VO concentration of each individual hazardous waste
stream at the point of waste origination must be determined using the
procedures specified in Section
724.983(a).
The average VO concentration of the hazardous waste at the point of waste
treatment must be determined using the procedures specified in Section
724.983(b).
F) A process that removes or
destroys the organics contained in the hazardous waste to a level such that the
organic reduction efficiency (R) for the process is equal to or greater than 95
percent and the owner or operator certifies that the average VO concentration
at the point of waste origination for each of the individual waste streams
entering the process is less than 10,000 ppmw. The organic reduction efficiency
for the process and the average VO concentration of the hazardous waste at the
point of waste origination must be determined using the procedures specified in
Section
724.983(b)
and Section
724.983(a),
respectively.
G) A hazardous waste
incinerator for which either of the following conditions is true:
i) The owner or operator has been issued a
final permit under 35 Ill. Adm. Code 702, 703, and 705 that implements the
requirements of Subpart H of 35 Ill. Adm. Code 726; or
ii) The owner or operator has designed and
operates the incinerator in accordance with the interim status requirements of
Subpart O of 35 Ill. Adm. Code 725.
H) A boiler or industrial furnace for which
either of the following conditions is true:
i) The owner or operator has been issued a
final permit under 35 Ill. Adm. Code 702, 703, and 705 that implements the
requirements of Subpart H of 35 Ill. Adm. Code 726; or
ii) The owner or operator has designed and
operates the boiler or industrial furnace in accordance with the interim status
requirements of Subpart O of 35 Ill. Adm. Code 725.
I) For the purpose of determining the
performance of an organic destruction or removal process in accordance with the
conditions in each of subsections (c)(2)(A) through (c)(2)(F), the owner or
operator must account for VO concentrations determined to be below the limit of
detection of the analytical method by using the following VO concentration:
i) If Reference Method 25D (Determination of
the Volatile Organic Concentration of Waste Samples) in appendix A to
40 CFR
60(Test Methods),
incorporated by reference in 35 Ill. Adm. Code
720.111(b),
is used for the analysis, one-half the blank value determined in Section 4.4 of
the method or a value of 25 ppmw, whichever is less.
ii) If any other analytical method is used,
one-half the sum of the limits of detection established for each organic
constituent in the waste that has a Henry's law constant value at least 0.1
mole-fraction-in-the-gas-phase/mole- fraction-in-the-liquid-phase (0.1 Y/X)
(which can also be expressed as
1.8 x
10-6
atmospheres/gram-mole/m3) at 25°
C.
3) A tank
or surface impoundment used for biological treatment of hazardous waste in
accordance with the requirements of subsection (c)(2)(D).

by the Agency pursuant to 35 Ill. Adm. Code
728.142(b).
5) A tank used for bulk feed of
hazardous waste to a waste incinerator and all of the following conditions are
met:
