(A)
Each owner or
operator subject to rules
3745-256-30 to
3745-256-35 of the
Administrative Code shall comply with the test methods and procedures
requirements provided in this rule.
(B)
When a
closed-vent system is tested for compliance with no detectable emissions, as
required in paragraph (K) of rule
3745-256-33 of the
Administrative Code, 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.

Calibration gases
shall be:
(a)
Zero air (less than ten parts per million (ppm) of
hydrocarbon in air).
(b)
A mixture of methane or n-hexane and air at a
concentration of approximately, but less than, ten thousand ppm methane or
n-hexane.
(5)
The background level shall be determined as provided in

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 ppm for determining compliance.
(C)
Performance tests
to determine compliance with paragraph (A) of rule
3745-256-32 of the
Administrative Code and with the total organic compound concentration limit of
paragraph (C) of rule
3745-256-33 of the
Administrative Code shall comply with the following:
(1)
Performance tests
to determine total organic compound concentrations and mass flow rates entering

(a)
Method 2 in 40
CFR Part 60 for velocity and volumetric flow rate.
(b)
Method 18 or

Where:
Eh = Total
organic mass flow rate, kilograms per hour (kg/h);
Q2sd =
Volumetric flow rate of gases entering or exiting control device, as determined
by method 2, standard cubic meter of dry gas per hour (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, kilogram per kilogram mole
(kg/kg-mol);
0.0416 = Conversion factor for molar
volume, kg-mol/m3 [at two nundred ninety-three
Kelvin and seven hundred sixty milligrams of mercury (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 (at two hundred ninety-three
Kelvin and seven hundred sixty mm Hg);
10-6 =
Conversion from ppm.
(e)
The annual total
organic emission rate shall be determined by the following equation:
EA =
(Eh)(H)
Where:
EA = Total
organic mass emission rate, kilograms per year (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
paragraph (C)(1)(d) of this rule] and by summing the annual total organic mass
emission rates [EA, as determined in paragraph (C)(1)(e) of this rule] 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 startup,
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 paragraph (C)(1) of this
rule.
(b)
Safe sampling platforms.
(c)
Safe access to
sampling platforms.
(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 shall 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 director'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 rules
3745-256-30 to
3745-256-35 of the
Administrative Code, 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 ten parts per million by
weight (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 shall 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 shall 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 offsite, the grab samples shall 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 of "Test Methods for Evaluating Solid Waste,
Physical/Chemical Methods," U.S. EPA publication SW-846; or 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 ten 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 ten ppmw,
or prior speciation analysis results on the same waste stream where it also can
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 ten ppmw shall be made as
follows:
(1)
By
the effective date that the facility becomes subject to rules
3745-256-30 to
3745-256-35 of the
Administrative Code 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 director 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 ten ppmw based on knowledge of the waste, the dispute may be resolved
using direct measurement as specified at paragraph (D)(1) of this rule.
