Current through Register Vol. 48, No. 9, September 27, 2024
(a) Each remanufacturer or other person that
stores or treats the hazardous secondary material subject to the provisions of
this subpart shall comply with the test methods and procedural requirements
provided in this section.
(b) When
a closed-vent system is tested for compliance with no detectable emissions, as
required in section 261.1033(l) of this subpart, the test shall comply with the
following requirements:
(1) Monitoring shall
comply with Reference Method 21 in 40 CFR part 60.
(2) The detection instrument shall meet the
performance criteria of Reference Method 21.
(3) The instrument shall be calibrated before
use on each day of its use by the procedures specified in Reference Method
21.
(4) Calibration gases shall be:
(i) Zero air (less than ten (10) parts per
million (ppm) of hydrocarbon in air).
(ii) A mixture of methane or n-hexane and air
at a concentration of approximately, but less than, ten thousand (10,000) ppm
methane or n-hexane.
(5)
The background level shall be determined as set forth in Reference Method
21.
(6) The instrument probe shall
be traversed around all potential leak interfaces as close to the interface as
possible as described in Reference Method 21.
(7) The arithmetic difference between the
maximum concentration indicated by the instrument and the background level is
compared with five hundred (500) ppm for determining compliance.
(c) Performance tests to determine
compliance with section 261.1032(a) and with the total organic compound
concentration limit of section 261.1033(c) shall comply with the following:
(1) Performance tests to determine total
organic compound concentrations and mass flow rates entering and exiting
control devices shall be conducted and data reduced in accordance with the
following reference methods and calculation procedures:
(i) Method 2 in 40 CFR part 60 for velocity
and volumetric flow rate.
(ii)
Method 18 or Method 25A in 40 CFR part 60, appendix A, for organic content. If
Method 25A is used, the organic HAP used as the calibration gas must be the
single organic HAP representing the largest percent by volume of the emissions.
The use of Method 25A is acceptable if the response from the high-level
calibration gas is at least twenty (20) times the standard deviation of the
response from the zero calibration gas when the instrument is zeroed on the
most sensitive scale.
(iii) Each
performance test shall consist of three separate runs; each run conducted for
at least one (1) hour under the conditions that exist when the hazardous
secondary material management unit is operating at the highest load or capacity
level reasonably expected to occur. For the purpose of determining total
organic compound concentrations and mass flow rates, the average of results of
all runs shall apply. The average shall be computed on a time-weighted
basis.
(iv) Total organic mass flow
rates shall be determined by the following equation:
(A) For sources utilizing Method 18.

Where:
Eh= Total organic mass flow rate,
kg/h;
Q2sd= Volumetric flow rate of gases
entering or exiting control device, as determined by Method 2, dscm/h;
n = Number of organic compounds in the vent gas;
Ci= Organic concentration in ppm,
dry basis, of compound "i" in the vent gas, as determined by Method 18;
MWi= Molecular weight of organic
compound "i" in the vent gas, kg/kg-mol;
0.0416 = Conversion factor for molar volume, kg-mol/m3
(@293 K and 760 mm Hg);
10-6 = Conversion from
ppm.
(B) For sources
utilizing Method 25A.
Eh=
(Q)(C)(MW)(0.0416)(10-6)
Where:
Eh= Total organic mass flow rate,
kg/h;
Q = Volumetric flow rate of gases entering or exiting
control device, as determined by Method 2, dscm/h;
C = Organic concentration in ppm, dry basis, as determined
by Method 25A;
MW = Molecular weight of propane, 44;
0.0416 = Conversion factor for molar volume, kg-mol/m3
(@293 K and 760 mm Hg);
10-6 = Conversion from
ppm.
(v) The
annual total organic emission rate shall be determined by the following
equation:
EA =
(Eh)(H)
Where:
EA = Total organic mass emission
rate, kg/y;
Eh = Total organic mass flow rate
for the process vent, kg/h;
H = Total annual hours of operations for the affected unit,
h.
(vi) Total organic
emissions from all affected process vents at the facility shall be determined
by summing the hourly total organic mass emission rates
(Eh, as determined in paragraph (c)(1)(iv) of this
section) and by summing the annual total organic mass emission rates
(EA, as determined in paragraph (c)(1)(v) of this
section) for all affected process vents at the facility.
(2) The remanufacturer or other person that
stores or treats the hazardous secondary material shall record such process
information as may be necessary to determine the conditions of the performance
tests. Operations during periods of startup, shutdown, and malfunction shall
not constitute representative conditions for the purpose of a performance
test.
(3) The remanufacturer or
other person that stores or treats the hazardous secondary material at an
affected facility shall provide, or cause to be provided, performance testing
facilities as follows:
(i) Sampling ports
adequate for the test methods specified in paragraph (c)(1) of this
section.
(ii) Safe sampling
platform(s).
(iii) Safe access to
sampling platform(s).
(iv)
Utilities for sampling and testing equipment.
(4) For the purpose of making compliance
determinations, the time-weighted average of the results of the three runs
shall apply. In the event that a sample is accidentally lost or conditions
occur in which one of the three runs must be discontinued because of forced
shutdown, failure of an irreplaceable portion of the sample train, extreme
meteorological conditions, or other circumstances beyond the remanufacturer's
or other person's that stores or treats the hazardous secondary material
control, compliance may, upon the Department's approval, be determined using
the average of the results of the two other runs.
(d) To show that a process vent associated
with a hazardous secondary material distillation, fractionation, thin-film
evaporation, solvent extraction, or air or steam stripping operation is not
subject to the requirements of this subpart, the remanufacturer or other person
that stores or treats the hazardous secondary material must make an initial
determination that the time-weighted, annual average total organic
concentration of the material managed by the hazardous secondary material
management unit is less than ten (10) ppmw using one of the following two (2)
methods:
(1) Direct measurement of the organic
concentration of the material using the following procedures:
(i) The remanufacturer or other person that
stores or treats the hazardous secondary material must take a minimum of four
(4) grab samples of material for each material stream managed in the affected
unit under process conditions expected to cause the maximum material organic
concentration.
(ii) For material
generated onsite, the grab samples must be collected at a point before the
material is exposed to the atmosphere such as in an enclosed pipe or other
closed system that is used to transfer the material after generation to the
first affected distillation, fractionation, thin-film evaporation, solvent
extraction, or air or steam stripping operation. For material generated
offsite, the grab samples must be collected at the inlet to the first material
management unit that receives the material provided the material has been
transferred to the facility in a closed system such as a tank truck and the
material is not diluted or mixed with other material.
(iii) Each sample shall be analyzed and the
total organic concentration of the sample shall be computed using Method 9060A
(incorporated by reference under section 260.11) of "Test Methods for
Evaluating Solid Waste, Physical/Chemical Methods," EPA Publication SW-846, or
analyzed for its individual organic constituents.
(iv) The arithmetic mean of the results of
the analyses of the four (4) samples shall apply for each material stream
managed in the unit in determining the time-weighted, annual average total
organic concentration of the material. The time-weighted average is to be
calculated using the annual quantity of each material stream processed and the
mean organic concentration of each material stream managed in the
unit.
(2) Using
knowledge of the material to determine that its total organic concentration is
less than ten (10) ppmw. Documentation of the material determination is
required. Examples of documentation that shall be used to support a
determination under this provision include production process information
documenting that no organic compounds are used, information that the material
is generated by a process that is identical to a process at the same or another
facility that has previously been demonstrated by direct measurement to
generate a material stream having a total organic content less than ten (10)
ppmw, or prior speciation analysis results on the same material stream where it
can also be documented that no process changes have occurred since that
analysis that could affect the material total organic concentration.
(e) The determination that
distillation, fractionation, thin-film evaporation, solvent extraction, or air
or steam stripping operations manage hazardous secondary materials with
time-weighted, annual average total organic concentrations less than ten (10)
ppmw shall be made as follows:
(1) By the
effective date that the facility becomes subject to the provisions of this
subpart or by the date when the material is first managed in a hazardous
secondary material management unit, whichever is later, and
(2) For continuously generated material,
annually, or
(3) Whenever there is
a change in the material being managed or a change in the process that
generates or treats the material.
(f) When a remanufacturer or other person
that stores or treats the hazardous secondary material and the Department do
not agree on whether a distillation, fractionation, thin-film evaporation,
solvent extraction, or air or steam stripping operation manages a hazardous
secondary material with organic concentrations of at least ten (10) ppmw based
on knowledge of the material, the dispute may be resolved by using direct
measurement as specified at paragraph (d)(1) of this section.
