equations. The TRE index is a decision tool used to determine if the annual
cost of controlling a given vent gas stream is acceptable when considering the
emissions reduction achieved.

minimum accuracy of plus or minus one percent (+- 1%) of the temperature being
monitored expressed in degrees Celsius or plus or minus (+-) 0.5

D. Where an absorber scrubs halo-genated
streams after an incinerator, boiler, or process heater, the following
monitoring equipment is required for the scrubber-
(I) A pH monitoring device equipped with a
continuous recorder; and
(II) Flow
meters equipped with continuous recorders to be located at the scrubber
influent for liquid flow and the scrubber inlet for gas stream flow.
5. The owner or
operator of a process vent using a vent system that contains bypass lines that
could divert a vent stream away from the combustion device used shall either-
A. Install, calibrate, maintain, and operate
a flow indicator that provides a record of vent stream flow at least once every
fifteen (15) minutes. The flow indicator shall be installed at the entrance to
any bypass line that could divert the vent stream away from the combustion
device to the atmosphere; or
B.
Secure the bypass line valve in the closed position with a car-seal or a
lock-and-key type configuration. A visual inspection of the seal or closure
mechanism shall be performed at least once every month to ensure that the valve
is maintained in the closed position and the vent stream is not diverted
through the bypass line.
(4) Reporting and Record Keeping.
(A) Each reactor process or distillation
operation subject to this rule shall keep records of the following parameters
measured during a performance test or TRE determination required under
subsection (3)(B) of this rule and required to be monitored under subsection
(3)(C) of this rule.
1. Where an owner or
operator subject to the provisions of this rule seeks to demonstrate compliance
with subparagraph (3)(A)1.A. of this rule through the use of either a thermal
or catalytic incinerator-
A. The average
firebox temperature of the incinerator (or the average temperature upstream and
downstream of the catalyst bed for a catalytic incinerator), measured at least
every fifteen (15) minutes and averaged over the same time period of the
performance testing; and
B. The
percent reduction of TOC determined as specified in paragraph (3)(B)3. of this
rule achieved by the incinerator, or the concentration of TOC (parts per
million by volume, by compound) determined as specified in paragraph (3)(B)3.
of this rule at the outlet of the control device on a dry basis corrected to
three percent (3%) oxygen.
2. Where an owner or
operator subject to the
provisions of this rule seeks to demonstrate compliance with subparagraph
(3)(A)1.A. of this rule through the use of a boiler or process heater and the
boiler or process heater is not exempt from these requirements due to all vent
streams being introduced with primary fuel-
A.
A description of the location at which the vent stream is introduced into the
boiler or process heater; and
B.
The average combustion temperature of the boiler or process heater with a
design heat input capacity of less than forty-four (44) megawatts measured at
least every fifteen (15) minutes and averaged over the same time period of the
performance test.
3.
Where an owner or operator subject to the provisions of this rule seeks to
demonstrate compliance with subparagraph (3)(A)1.B. of this rule through the
use of a smokeless flare; flare design (i.e., steam-assisted, air-assisted, or
nonassisted), all visible emission readings, heat content determinations, flow
rate measurements, and exit velocity determinations made during the performance
test, continuous records of the flare pilot flame monitoring, and records of
all periods of operations during which the pilot flame is absent.
4. Where an owner or
operator subject to the
provisions of this rule seeks to demonstrate compliance with paragraph (3)(A)2.
of this rule-
A. All measurements and
calculations performed to determine the flow rate, and volatile organic
compound concentration, heating value, and TRE index value of the vent stream;
and
B. Records shall be kept of the
following final recovery device parameters:
(I) Where an absorber is the final recovery
device in the recovery system, the exit specific gravity (or alternative
parameter which is a measure of the degree of absorbing liquid saturation, if
approved, by the permitting authority), and average exit temperature of the
absorbing liquid measured at least fifteen (15) minutes and averaged over the
same time period of the performance testing (both measured while the vent
stream is normally routed and constituted);
(II) Where a condenser is the final recovery
device in the recovery system, the average exit (product side) temperature
measured at least every fifteen (15) minutes and averaged over the same time
period of the performance testing while the vent stream is routed and
constituted normally; or
(III)
Where a carbon adsorber is the final recovery device in the recovery system,
the total stream mass or volumetric flow measured at least every fifteen (15)
minutes and averaged over the same time period of the performance test (full
carbon bed cycle), temperature of the carbon bed after regeneration (and within
fifteen (15) minutes of completion of any cooling cycle(s)), and duration of
the carbon bed steaming cycle (all measured while the vent stream is routed and
constituted normally).
5. As an alternative to subparagraphs
(4)(A)4.A. or (4)(A)4.B. of this rule, the concentration level or reading
indicated by the organics monitoring device at the outlet of the absorber,
condenser, or carbon adsorber, measured at least every fifteen (15) minutes and
averaged over the same time period as the performance testing while the vent
stream is normally routed and constituted.
(B) Each reactor process or distillation
operation seeking to comply with paragraph (3)(A)2. of this rule shall also
keep records of the following information:
1.
Any changes in production capacity, feedstock type, or catalyst type, or of any
replacement, removal, and addition of recovery equipment or reactors and
distillation units; and
2. Any
recalculation of the flow rate, TOC concentration, or TRE value performed
according to paragraph (3)(B)7. of this rule.
(C) Each reactor process or distillation
operation seeking to comply with the flow rate or concentration exemption level
in paragraph (1)(B)4. of this rule shall keep records to indicate that the
stream flow rate is less than 0.0085 standard cubic meters per minute or the
concentration is less than five hundred (500) parts per million by
volume.
(D) Each reactor process or
distillation operation seeking to comply with the production capacity exemption
level of one (1) giga-gram per year shall keep records of the design production
capacity and changes in equipment or process operation that may affect design
production capacity to the affected process unity.
(E) All records must be kept on-site for a
period of five (5) years and made available to the department upon
request.
