Ill. Admin. Code tit. 35, § 721.983 - Material Determination Procedures
a) Procedure to Determine Average Volatile
Organic (VO) Concentration
1) Determining
average VO concentration at the point of material origination. A remanufacturer
or other person that stores or treats the hazardous secondary material must
determine the average VO concentration at the point of material origination for
each hazardous secondary material placed in a hazardous secondary material
management unit exempted under the provisions of Section
721.982(c) from
using air emission controls in compliance with standards specified in Sections
721.984 through
721.987, as applicable to the
hazardous secondary material management unit.
A) An initial determination of the average VO
concentration of the material stream must be made before the first time any
portion of the material in the hazardous secondary material stream is placed in
a hazardous secondary material management unit exempted under the provisions of
Section 721.982(c) from
using air emission controls, and thereafter an initial determination of the
average VO concentration of the material stream must be made for each averaging
period that a hazardous secondary material is managed in the unit;
and
B) Perform a new material
determination whenever changes to the source generating the material stream are
reasonably likely to cause the average VO concentration of the hazardous
secondary material to increase to a level that is equal to or greater than the
applicable VO concentration limits specified in Section
721.982.
2) Determining
average VO concentration using direct measurement or knowledge. For a material
determination that is required by subsection (a)(1), the average VO
concentration of a hazardous secondary material at the point of material
origination must be determined using either direct measurement, as specified in
subsection (a)(3), or by knowledge of the hazardous secondary material, as
specified in subsection (a)(4).
3)
Direct measurement to determine average VO concentration of a hazardous
secondary material at the point of material origination, as follows:
A) Identification. The remanufacturer or
other person that stores or treats the hazardous secondary material must
identify and record in a log that is kept at the facility the point of material
origination for the hazardous secondary material.
B) Sampling. Samples of the hazardous
secondary material stream must be collected at the point of material
origination in a manner so that volatilization of organics contained in the
material and in the subsequent sample is minimized and an adequately
representative sample is collected and maintained for analysis by the selected
method.
i) The averaging period to be used for
determining the average VO concentration for the hazardous secondary material
stream on a mass-weighted average basis must be designated and recorded. The
averaging period can represent any time interval that the remanufacturer or
other person that stores or treats the hazardous secondary material determines
is appropriate for the hazardous secondary material stream but must not exceed
one year.
ii) Enough samples, but
at least four, must be collected and analyzed for a hazardous secondary
material determination . The samples for a given material determination must be
collected within a one-hour period. The average of the four or more sample
results constitutes a material determination for the material stream. One or
more material determinations may be required to represent the complete range of
material compositions and quantities that occur during the entire averaging
period due to normal variations in the operating conditions for the source or
process generating the hazardous secondary material stream. Examples of these
normal variations are seasonal variations in material quantity or fluctuations
in ambient temperature.
iii) All
samples must be collected and handled according to written procedures prepared
by the remanufacturer or other person that stores or treats the hazardous
secondary material and documented in a site sampling plan. This plan must
describe the procedure by which representative samples of the hazardous
secondary material stream are collected so that a minimum loss of organics
occurs throughout the sample collection and handling process, and by which
sample integrity is maintained. A copy of the written sampling plan must be
maintained at the facility . An example of acceptable sample collection and
handling procedures for a total volatile organic constituent concentration may
be found in 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.
iv) Sufficient information, as specified in
the "site sampling plan" required under subsection (a)(3)(B)(iii), must be
prepared and recorded to document the material quantity represented by the
samples and, as applicable, the operating conditions for the source or process
generating the hazardous secondary material represented by the
samples.
C) Analysis.
Each collected sample must be prepared and analyzed according to 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, for the total concentration of volatile organic
constituents, or using one or more methods when the individual organic compound
concentrations are identified and summed and the summed material concentration
accounts for and reflects all organic compounds in the material with Henry's
law constant values 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 [CROSS]
10-6
atmospheres/gram-mole/m3) at 25 °C. At the
discretion of the remanufacturer or other person that stores or treats the
hazardous secondary material, the test data obtained may be adjusted by any
appropriate method to discount any contribution to the total volatile organic
concentration that is a result of including a compound with a Henry's law
constant value of less than 0.1 Y/X at 25 °C. To adjust these data, the
measured concentration of each individual chemical constituent contained in the
material is multiplied by the appropriate constituent-specific adjustment
factor (fm25D). If the remanufacturer or other person
that stores or treats the hazardous secondary material elects to adjust the
test data, the adjustment must be made to all individual chemical constituents
with a Henry's law constant value greater than or equal to 0.1 Y/X at 25 °C
contained in the material. To adjust these data, the measured concentration of
each individual chemical constituent contained in the waste is multiplied by
the constituent-specific adjustment factors (fm25D)
approved in writing by the Agency. Other test methods may be used if they meet
the requirements in subsection (a)(3)(C)(i) or (a)(3)(C)(ii) and provided the
requirement to reflect all organic compounds in the material with Henry's law
constant values greater than or equal to 0.1 Y/X (which can also be expressed
as 1.8 [CROSS]
10-6
atmospheres/gram-mole/m3) at 25 °C, is met.
i) Any USEPA standard method that has been
validated in compliance with appendix D to 40 CFR 63 (Alternative Validation
Procedure for EPA Waste and Wastewater Methods), incorporated by reference in
35 Ill. Adm. Code 720.111.
ii) Any
other analysis method that has been validated in according to the procedures
specified in Section 5.1 or Section 5.3, and the corresponding calculations in
Section 6.1 or Section 6.3, of Method 301 (Field Validation of Pollutant
Measurement Methods from Various Waste Media) in appendix A to 40 CFR 63 (Test
Methods), incorporated by reference in 35 Ill. Adm. Code 720.111. The data are
acceptable if they meet the criteria specified in Section 6.1.5 or Section
6.3.3 of Method 301. If correction is required under section 6.3.3 of Method
301, the data are acceptable if the correction factor is within the range 0.7
to 1.30. Other sections of Method
301 are not required.
D)
Calculations
i) The average VO concentration
(C[BAR]) on a mass-weighted basis must be calculated by using the results for
all material determinations conducted in compliance with subsections (a)(3)(B)
and (a)(3)(C) and the following equation:

ii)
For determining Ci, for individual material samples
analyzed in compliance with subsection (a)(3)(C), the remanufacturer or other
person that stores or treats the hazardous secondary material must account for
VO concentrations determined to be below the detection limit of the analytical
method by using the VO concentration that is one-half the blank value
determined in the method at section 4.4 of Reference Method 25D, if Reference
Method 25D is used for the analysis; or that is one-half the sum of the limits
of detection established for each organic constituent in the material that has
a Henry's law constant values 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
×
10-6atmospheres/gram-mole/m3)
at 25 °C, if any other analytical method is used.
4) Use of knowledge by the
remanufacturer or other person that stores or treats the hazardous secondary
material to determine average VO concentration of a hazardous secondary
material at the point of material origination.
A) Documentation must be prepared that
presents the information used as the basis for the knowledge by the
remanufacturer or other person that stores or treats the hazardous secondary
material of the hazardous secondary material stream's average VO concentration .
Examples of information that may be used as the basis for knowledge include
material balances for the source or process generating the hazardous secondary
material stream; constituent-specific chemical test data for the hazardous
secondary material stream from previous testing that are still applicable to
the current material stream; previous test data for other locations managing
the same type of material stream; or other knowledge based on information
included in shipping papers or material certification notices.
B) If test data are used as the basis for
knowledge, then the remanufacturer or other person that stores or treats the
hazardous secondary material must document the test method, sampling protocol,
and the means by which sampling variability and analytical variability are
accounted for in determining the average VO concentration . For example, a
remanufacturer or other person that stores or treats the hazardous secondary
material may use organic concentration test data for the hazardous secondary
material stream that are validated according to Method 301 (Field Validation of
Pollutant Measurement Methods from Various Waste Media) in appendix A to 40 CFR
63 (Test Methods) as the basis for knowledge of the material.
C) A remanufacturer or other person that
stores or treats the hazardous secondary material using chemical
constituent-specific concentration test data as the basis for knowledge of the
hazardous secondary material may adjust the test data to the corresponding
average VO concentration value that would have been obtained had the material
samples been analyzed using 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). To
adjust these data, the measured concentration for each individual chemical
constituent contained in the material is multiplied by the appropriate
constituent-specific adjustment factor
(fm25D).
D)
In the event that the Agency and the remanufacture or other person that stores
or treats the hazardous secondary material disagree on a determination of the
average VO concentration for a hazardous secondary material stream using
knowledge, then the results from a determination of average VO concentration
using direct measurement, as specified in subsection (a)(3), must be used to
establish compliance with the applicable requirements of this Subpart CC. The
Agency may perform or request that the remanufacturer or other person that
stores or treats the hazardous secondary material perform this determination
using direct measurement. The remanufacturer or other person that stores or
treats the hazardous secondary material may choose one or more appropriate
methods to analyze each collected sample under subsection (a)(3)(C). The Agency
must state any disagreement on determination of the average VO concentration
for a hazardous secondary material stream using knowledge in writing to the
remanufacturer or other person that stores or treats the hazardous secondary
material.
b)
This subsection (b) corresponds with
40 CFR
261.1083(b), marked
"reserved" by USEPA. This statement maintains structural consistency with the
federal regulations.
c) Procedure
to Determine the Maximum Organic Vapor Pressure of a Hazardous Secondary
Material in a Tank
1) A remanufacturer or
other person that stores or treats the hazardous secondary material must
determine the maximum organic vapor pressure for each hazardous secondary
material placed in a tank using Tank Level 1 controls in compliance with
standards specified in Section
721.984(c).
2) A remanufacturer or other person that
stores or treats the hazardous secondary material must use either direct
measurement as specified in subsection (c)(3) or knowledge of the waste as
specified by subsection (c)(4) to determine the maximum organic vapor pressure
that is representative of the hazardous secondary material composition stored
or treated in the tank.
3) Direct
Measurement to Determine the Maximum Organic Vapor Pressure of a Hazardous
Secondary Material
A) Sampling. Enough samples
must be collected to be representative of the hazardous secondary material
contained in the tank. All samples must be collected and handled according to
written procedures prepared by the remanufacturer or other person that stores
or treats the hazardous secondary material and documented in a site sampling
plan. This plan must describe the procedure by which representative samples of
the hazardous secondary material are collected so that a minimum loss of
organics occurs throughout the sample collection and handling process and by
which sample integrity is maintained. A copy of the written sampling plan must
be maintained at the facility . An example of acceptable sample collection and
handling procedures may be found in 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).
B) Analysis. Any appropriate one of the
following methods may be used to analyze the samples and compute the maximum
organic vapor pressure of the hazardous secondary material:
i) Reference Method 25E (Determination of
Vapor Phase Organic Concentration in Waste Samples) in appendix A to 40 CFR 60
(Test Methods), incorporated by reference in 35 Ill. Adm. Code
720.111(b);
ii) Methods described in American Petroleum
Institute Publication 2517, Third Edition, February 1989, "Evaporative Loss
from External Floating-Roof Tanks", incorporated by reference in 35 Ill. Adm.
Code 720.111;
iii) Methods obtained
from standard reference texts;
iv)
ASTM Method 2879-92, incorporated by reference in 35 Ill. Adm. Code 720.111;
and
v) Any other method approved in
writing by the Agency.
4) Use of Knowledge to Determine the Maximum
Organic Vapor Pressure of the Hazardous Secondary Material. Documentation must
be prepared and recorded that presents the information used as the basis for
the knowledge by the remanufacturer or other person that stores or treats the
hazardous secondary material that the maximum organic vapor pressure of the
hazardous secondary material is less than the maximum vapor pressure limit
listed in Section 721.984(b)(1)(A)
for the applicable tank design capacity category. An example of information
that may be used is documentation that the hazardous secondary material is
generated by a process for which at other locations it previously has been
determined by direct measurement that the hazardous secondary material's waste
maximum organic vapor pressure is less than the maximum vapor pressure limit
for the appropriate tank design capacity category.
d) Procedure for Determining No Detectable
Organic Emissions for the Purpose of Complying with this Subpart CC
1) The test must be conducted according to
the procedures specified in Reference Method 21 (Determination of Volatile
Organic Compound Leaks) in appendix A to 40 CFR 60 (Test Methods), incorporated
by reference in 35 Ill. Adm. Code 720.111. Each potential leak interface (i.e.,
a location if organic vapor leakage could occur) on the cover and associated
closure devices must be checked. Potential leak interfaces that are associated
with covers and closure devices include the interface of the cover and its
foundation mounting, the periphery of any opening on the cover and its
associated closure device , and the sealing seat interface on a spring-loaded
pressure relief valve.
2) The test
must be performed when the unit contains a hazardous secondary material having
an organic concentration representative of the range of concentrations for the
hazardous secondary material expected to be managed in the unit. During the
test, the cover and closure devices must be secured in the closed
position.
3) The detection
instrument must meet the performance criteria of Reference Method 21, except
the instrument response factor criteria in section 3.1.2(a) of Reference Method
21, must be for the average composition of the organic constituents in the
hazardous secondary material placed in the hazardous secondary management unit,
not for each individual organic constituent.
4) The detection instrument must be
calibrated before use on each day of its use by the procedures specified in
Reference Method 21.
5) Calibration
gases must be as follows:
A) Zero air (less
than 10 ppmv hydrocarbon in air); and
B) A mixture of methane or n-hexane and air
at a concentration of approximately, but less than, 10,000 ppmv methane or
n-hexane.
6) The
background level must be determined according to the procedures in Reference
Method 21.
7) Each potential leak
interface must be checked by traversing the instrument probe around the
potential leak interface as close to the interface as possible, as described in
Reference Method 21. If the configuration of the cover or closure device
prevents a complete traverse of the interface, all accessible portions of the
interface must be sampled. If the configuration of the closure device prevents
any sampling at the interface and the device is equipped with an enclosed
extension or horn (e.g., some pressure relief devices), the instrument probe
inlet must be placed at approximately the center of the exhaust area to the
atmosphere.
8) The arithmetic
difference between the maximum organic concentration indicated by the
instrument and the background level must be compared with the value of 500 ppmv
except when monitoring a seal around a rotating shaft that passes through a
cover opening, in which case the comparison must be as specified in subsection
(d)(9). If the difference is less than 500 ppmv, then the potential leak
interface is determined to operate with no detectable organic
emissions .
9) For the seals around
a rotating shaft that passes through a cover opening, the arithmetic difference
between the maximum organic concentration indicated by the instrument and the
background level must be compared with the value of 10,000 ppmw. If the
difference is less than 10,000 ppmw, then the potential leak interface is
determined to operate with no detectable organic emissions .
