Affected: IC 13-15; IC 13-17
Sec. 5.
(a) Upon the
commissioner's request, the owner or operator of a batch process train or unit
operation within a batch process train shall conduct testing to demonstrate
compliance with section 3 this rule. The owner or operator shall, at its own
expense, conduct the tests in accordance with the applicable test methods and
procedures specified in subsections (d), (e), and (f).
(b) Notwithstanding subsection (a), flares
and process boilers used to comply with the control requirements of section 3
of this rule shall be exempt from compliance testing requirements.
(c) When a flare is used to comply with the
control requirements of section 3 of this rule, the flare shall comply with the
requirements of 40 CFR 60.18 *.
(d)
The owner or operator of a batch process train or unit operation within a batch
process train that is exempt from the control requirements of section 3 of this
rule due to:
(1) an average flow rate that is
equal to or above the calculated applicability flow rate; or
(2) a VOC concentration of less than or equal
to five hundred (500) ppmv (unit operation); shall demonstrate, upon the
commissioner's request, the absence of oversized gas moving equipment in any
manifold. Gas moving equipment shall be considered oversized if it exceeds the
maximum requirements of the exhaust flow rate by more than thirty percent
(30%).
(e) For the
purpose of demonstrating compliance with the control requirements in section 3
of this rule, the batch process train or unit operation shall be run at
representative operating conditions and flow rates during any compliance
test.
(f) The following methods in
40 CFR 60, Appendix A* shall be used to demonstrate compliance with the
reduction efficiency requirement set forth in section 3 of this rule:
(1) U.S. EPA Method 1 or 1A, as appropriate,
for selection of the sampling sites if the flow measuring device is not a
rotameter. The control device inlet sampling site for determination of vent
stream VOC composition reduction efficiency shall be prior to the control
device and after the control device.
(2) U.S. EPA Method 2, 2A, 2B, 2C, or 2D, as
appropriate, for determination of gas stream volumetric flow rate flow
measurements, which shall be taken continuously. No traverse is necessary when
the flow measuring device is an ultrasonic probe.
(3) U.S. EPA Method 25A or U.S. EPA Method
18, if applicable, to determine the concentration of VOC in the control device
inlet and outlet as follows:
(A) The sampling
time for each run shall be as follows:
(i) For
batch cycles less than eight (8) hours in length, readings shall be taken
continuously over the entire length of the batch cycle with a maximum of
fifteen (15) minute intervals between measurements if using U.S. EPA Method
25A. If using U.S. EPA Method 18, readings shall be taken continuously with a
maximum of fifteen (15) minute intervals between measurements throughout the
batch cycle unless it becomes necessary to change the impinger train, in which
case a thirty (30) minute interval shall not be exceeded.
(ii) For batch cycles of eight (8) hours and
greater in length, the owner or operator may either test in accordance with the
test procedures defined in item (i) or the owner or operator may elect to
perform tests, pursuant to either U.S. EPA Method 25A or U.S. EPA Method 18,
only during those portions of each emission event that define the emission
profile of each emission event occurring within the batch cycle. For each
emission event of less than four (4) hours in duration, the owner or operator
shall test continuously over the entire emission event as set forth in item
(i). For each emission event of greater than four (4) hours in duration, the
owner or operator shall elect either to perform a minimum of three (3) one (1)
hour test runs during the emission event or shall test continuously over the
entire emission event within each unit operation in the batch process train. To
demonstrate that the portion of the emission event to be tested defines the
emission profile for the emission event, the owner or operator electing to rely
on this option shall develop an emission profile for the entire emission event.
The emission profile shall be based upon either process knowledge or test data
collected. Examples of information that could constitute process knowledge
include, but are not limited to, calculations based on material balances and
process stoichiometry. Previous test results may be used provided the results
are still relevant to the current process vent stream conditions.
(B) The mass emission rate from
the process vent or inlet to the control device shall be determined by
combining concentration and flow rate measurements taken simultaneously at
sampling sites selected in accordance with subdivision (1) throughout the batch
cycle.
(C) The mass emission rate
from the control device outlet shall be obtained by combining concentration and
flow rate measurements taken simultaneously at sampling sites selected in
accordance with subdivision (1) throughout the batch cycle.
(D) The efficiency of the control device
shall be determined by integrating the mass emission rates obtained in clauses
(B) and (C) over the time of the batch cycle and dividing the difference in
inlet and outlet mass flow totals by the inlet mass flow total.
(g) The owner or
operator of a batch process train or unit operation may propose an alternative
test method or procedures to demonstrate compliance with the control
requirements set forth in section 3 of this rule. The method or procedures
shall be:
(1) approved by the commissioner and
U.S. EPA in writing; and
(2)
included as federally enforceable permit conditions.
(h) In the absence of a request by the
commissioner to conduct compliance testing in accordance with provisions of
this rule, the owner or operator may demonstrate compliance by the use of
engineering estimates or process stoichiometry.
(i) During the compliance test conducted to
demonstrate compliance with the control requirements of section 3 of this rule,
the owner or operator shall establish the operating limits (operating parameter
values) for the monitoring devices required under section 6 of this rule.
