Current through Register Vol. 50, No. 9, September 20, 2024
A.
Each owner or operator subject to the provisions of this Subchapter shall
comply with the test methods and procedures requirements provided in this
Section.
B. When a closed-vent
system is tested for compliance with no detectable emissions, as required in
LAC 33:V.1709.L, the test shall comply with the following requirements.
1. Monitoring shall comply with Reference
Method 21 in 40 CFR Part 60, Appendix A, incorporated by reference in LAC
33:III.3003.
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:
a. zero air (less than 10 ppm
of hydrocarbon in air);
b. a
mixture of methane or n-hexane and air at a concentration of approximately, but
less than, 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 500 ppm for determining compliance.
C. Performance tests to determine compliance
with LAC 33:V.1707.A and with the total organic compound concentration limit of
LAC 33:V.1709.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:
a. Method 2 in 40 CFR Part 60, Appendix A,
incorporated by reference in LAC 33:III.3003, for velocity and volumetric flow
rate;
b. Method 18 or Method 25A in
40 CFR Part 60, Appendix A, incorporated by reference in LAC 33:III.3003, for
organic content. If Method 25A is used, the organic hazardous air pollutants
(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 20
times the standard deviation of the response from the zero calibration gas when
the instrument is zeroed on the most sensitive scale.
c. Each performance test shall consist of
three separate runs; each run shall be conducted for at least one hour under
the conditions that exist when the hazardous waste 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.
d. Total organic mass flow rates shall be
determined by one of the following equations:
i. for sources utilizing Method 18:

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
ii. 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
e. The annual
total organic emission rate shall be determined by the following equation.

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
f. 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 LAC 33:V.1711.C.1.d) and by summing
the annual total organic mass emission rates (EA, as
determined in LAC 33:V.1711.C.1.e) for all affected process vents at the
facility.
2. The owner or
operator shall record such process information as may be necessary to determine
the conditions of the performance tests. Operations during periods of start-up,
shutdown, and malfunction shall not constitute representative conditions for
the purpose of a performance test.
3. The owner or operator of an affected
facility shall provide, or cause to be provided, performance testing facilities
as follows:
a. sampling ports adequate for the
test methods specified in LAC 33:V.1711.C.1;
b. safe sampling platform(s);
c. safe access to sampling platform(s);
and
d. 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 owner or operator's control, compliance may, upon the administrative
authority'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 waste distillation,
fractionation, thin-film evaporation, solvent extraction, or air or steam
stripping operation is not subject to the requirements of this Subchapter, the
owner or operator must make an initial determination that the time-weighted,
annual average total organic concentration of the waste managed by the waste
management unit is less than 10 ppmw using one of the following two methods.
1. Direct measurement of the organic
concentration of the waste using the following procedures.
a. The owner or operator must take a minimum
of four grab samples of waste for each waste stream managed in the affected
unit under process conditions expected to cause the maximum waste organic
concentration.
b. For waste
generated on-site, the grab samples must be collected at a point before the
waste is exposed to the atmosphere such as in an enclosed pipe or other closed
system that is used to transfer the waste after generation to the first
affected distillation, fractionation, thin-film evaporation, solvent
extraction, or air or steam stripping operation. For waste generated off-site,
the grab samples must be collected at the inlet to the first waste management
unit that receives the waste provided the waste has been transferred to the
facility in a closed system such as a tank truck and the waste is not diluted
or mixed with other waste.
c. Each
sample shall be analyzed, and the total organic concentration of the sample
shall be computed using Method 9060A (incorporated by reference in LAC
33:V.110) of Test Methods for Evaluating Solid Waste, Physical/Chemical
Methods, EPA Publication SW-846, or each sample shall be analyzed for
its individual organic constituents.
d. The arithmetic mean of the results of the
analyses of the four samples shall apply for each waste stream managed in the
unit in determining the time-weighted, annual average total organic
concentration of the waste. The time-weighted average is to be calculated using
the annual quantity of each waste stream processed and the mean organic
concentration of each waste stream managed in the unit.
2. Using knowledge of the waste to determine
that its total organic concentration is less than 10 ppmw. Documentation of the
waste 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 waste 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 waste stream having a total organic content less than 10 ppmw, or
prior speciation analysis results on the same waste stream where it can also be
documented that no process changes have occurred since that analysis that could
affect the waste total organic concentration.
E. The determination that distillation,
fractionation, thin-film evaporation, solvent extraction, or air or steam
stripping operations manage hazardous wastes with time-weighted, annual average
total organic concentrations less than 10 ppmw shall be made as follows:
1. by the effective date that the facility
becomes subject to the provisions of this Subchapter or by the date when the
waste is first managed in a waste management unit, whichever is later;
and
2. for continuously generated
waste, annually; or
3. whenever
there is a change in the waste being managed or a change in the process that
generates or treats the waste.
F. When an owner or operator and the
administrative authority do not agree on whether a distillation, fractionation,
thin-film evaporation, solvent extraction, or air or steam stripping operation
manages a hazardous waste with organic concentrations of at least 10 ppmw based
on knowledge of the waste, the dispute may be resolved by using direct
measurement as specified in Paragraph D.1 of this Section.
