(3) Performance tests to determine compliance
with s.
NR 664.1032(1) and with the total
organic compound concentration limit of s.
NR 664.1033(3) shall comply with all of
the following:
(a) Conduct performance tests
to determine total organic compound concentrations and mass flow rates entering
and exiting control devices and reduce data according to all of the following
methods and calculation procedures:
1. Method
2 in appendix A of 40 CFR part 60, incorporated by reference in s.
NR 660.11, for velocity and volumetric flow
rate.
2. Method 18 or Method 25A in
Appendix A of 40 CFR part 60, incorporated by reference in s.
NR 660.11, for organic content. If Method 25A is used,
the organic HAP used as the calibration gas shall 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.
3. Each performance test shall consist of 3
separate runs; conduct each run 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, average the results
of all runs. Compute the average on a time-weighted basis.
4. Determine total organic mass flow rates by
the following equation:
a. For sources using
Method 18.

where:
Eh = Total organic mass flow rate,
kg/h
Q 2sd = Volumetric flow rate of
gases entering or exiting control device, 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, determined by Method 18
MW i = Molecular weight of organic
compound i in the vent gas, kg/kg-mol
0.0416 = Conversion factor for molar volume,
kg-mol/m3 (at 293 K and 760 mm Hg)
10-6 = Conversion from
ppm
b. For sources using
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 (at
293 K and 760 mm Hg)
10-6 = Conversion from
ppm.
5. Determine
the annual total organic emission rate 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
6. Determine total organic
emissions from all affected process vents at the facility by summing the hourly
total organic mass emission rates (E h, determined in subd. 4.) and by summing
the annual total organic mass emission rates (E A, determined in subd. 5.) for
all affected process vents at the facility.
(b) Record the process information as may be
necessary to determine the conditions of the performance tests. Operations
during periods of startup, shutdown and malfunction may not constitute
representative conditions for the purpose of a performance test.
(c) For an affected facility, provide, or
cause to be provided, all of the following performance testing facilities:
1. Sampling ports adequate for the test
methods specified in par. (a).
2. A
safe sampling platform or platforms.
3. Safe access to the sampling platform or
platforms.
4. Utilities for
sampling and testing equipment.
(d) For the purpose of making compliance
determinations, use the time-weighted average of the results of the 3 runs. In
the event that a sample is accidentally lost or conditions occur in which one
of the 3 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 department's approval, be determined using the average of the results
of the 2 other runs.
(4)
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 this subchapter, the owner or operator
shall 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 2 methods:
(a)
Direct measurement of the organic
concentration of the waste. This method requires all of the following:
1. Take a minimum of 4 grab samples of waste
for each waste stream managed in the affected unit under process conditions
expected to cause the maximum waste organic concentration.
2. For waste generated onsite, collect the
grab samples 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, collect the grab samples 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.
3. Analyze each sample and compute the total
organic concentration of the sample using Method 9060A of EPA SW-846,
incorporated by reference in s.
NR 660.11, or analyze for its individual organic
constituents.
4. Use the arithmetic
mean of the results of the analyses of the 4 samples for each waste stream
managed in the unit in determining the time-weighted, annual average total
organic concentration of the waste. Calculate the time-weighted average using
the annual quantity of each waste stream processed and the mean organic
concentration of each waste stream managed in the unit.
(b)
Using knowledge of the waste to
determine that its total organic concentration is less than 10 ppmw.
This method requires documentation of the waste determination. Examples of
documentation that shall be used to support a determination under this
paragraph 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.
(5) Make 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 according to pars. (a) and (b)
or (c):
(a) By the effective date that the
facility becomes subject to this subchapter or by the date when the waste is
first managed in a waste management unit, whichever is later.
(b) For continuously generated waste,
annually.
(c) Whenever there is a
change in the waste being managed or a change in the process that generates or
treats the waste.
(6)
When an owner or operator 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 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 sub. (4)
(a).
