Utah Admin. Code R315-261-1034 - Air Emission Standards for Process Vents - Test Methods and Procedures
(a) Each
remanufacturer or other person that stores or treats the hazardous secondary
material subject to the provisions of Sections
R315-261-1030
through 1035 shall comply with the test methods and procedural requirements
provided in Section R315-261-1034.
(b) When a closed-vent system is tested for
compliance with no detectable emissions, as required in Subsection
R315-261-1033(l),
the test shall comply with the following requirements:
(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 10 ppm of hydrocarbon in air.
(ii) 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 Subsection
R315-261-1032(a)
and with the total organic compound concentration limit of Subsection
R315-261-1033(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 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.
(iii) Each performance test shall consist of
three separate runs; each run conducted for at least 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.
The equation found in 40 CFR 261.1034(c)(1)(iv)(A), 2015 ed. is adopted and incorporated by reference
Where:
E h= Total organic mass flow rate, kg/h;
Q 2sd= 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;
C i= Organic concentration in ppm, dry basis, of compound i in the vent gas, as 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 utilizing
Method 25A.
E h= (Q)(C)(MW)(0.0416)(10 -6)
Where:
E h= 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.
(v) The annual total organic emission rate
shall be determined by the following equation:
E A=(E h)(H)
Where:
E A=Total organic mass emission rate, kg/y;
E h=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, E
h, as determined in Subsection R315-261-1034(c)(1)(iv),
and by summing the annual total organic mass emission rates, E
A, as determined in Subsection R315-261-1034(c)(1)(v),
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 Subsection R315-261-1034(c)(1).
(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 shall 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 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 secondary material distillation,
fractionation, thin-film evaporation, solvent extraction, or air or steam
stripping operation is not subject to the requirements of Sections
R315-261-1030
through 1035, the remanufacturer or other person that stores or treats the
hazardous secondary material shall 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 10
ppmw using one of the following two 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 shall take a minimum of four
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 shall 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 shall 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
R315-260-11, 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 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 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 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 10 ppmw shall be made as
follows:
(1) By the effective date that the
facility becomes subject to the provisions of Sections
R315-261-1030
through 1035 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 Director 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 10 ppmw based on knowledge of
the material, the dispute may be resolved by using direct measurement as
specified at Subsection R315-261-1034(d)(1).
