Sec. 10.
(a) Sources that choose to meet the emission limit requirements of section 3 of this rule with the use of a control device or devices shall install, calibrate, maintain, and operate, according to the manufacturer's specification, the following monitoring equipment unless an alternative monitoring procedure has been approved by the department:
(1) If a thermal
incinerator is used for VOC reduction, a temperature monitoring device capable
of continuously recording the temperature of the gas stream in the combustion
zone of the incinerator shall be used. The temperature monitoring device shall
have an accuracy of one percent (1%) of the temperature being measured in
degrees centigrade or plus or minus five-tenths degree Centigrade (±
0.5°C), whichever is greater.
(2) If a catalytic incinerator is used for
VOC reduction, a temperature device capable of continuously recording the
temperature in the gas stream immediately before and after the catalyst bed of
the incinerator shall be used. The temperature monitoring device shall have an
accuracy of one percent (1%) of the temperature being measured in degrees
centigrade plus or minus five-tenths degree Centigrade (± 0.5°C),
whichever is greater.
(3) If a
carbon adsorber is used to remove and recover VOC from the gas stream, a VOC
monitoring device capable of continuously recording the concentration level of
VOC at the outlet of the carbon bed shall be used. The monitoring device shall
be based on a detection principle such as infrared, photoionization, or thermal
conductivity.
(4) Where a VOC
recovery device other than a carbon adsorber is used, the source shall provide
to the department information describing the operation of the device and the
process parameters which would indicate proper operation and maintenance of the
control device. The department may request further information and will specify
appropriate monitoring procedures and reporting requirements.
(b) Sources subject to the requirements of this section shall maintain the following records:
(1) A log of the operating time of the
facility and the facility's capture system, control device, and monitoring
equipment.
(2) A maintenance log
for the capture system, the control device, and the monitoring equipment
detailing all routine and nonroutine maintenance performed. The log shall
include the dates and duration of any outages of the capture system, the
control device, or the monitoring system.
(3) The following additional records shall be
maintained for facilities using thermal incinerators:
(A) Continuous records of the temperature in
the gas stream in the combustion zone of the incinerator.
(B) Records of all three (3) hour periods of
operation for which the average combustion temperature of the gas stream in the
combustion zone was more than fifty degrees Fahrenheit (50°F) below the
combustion zone temperature which existed during the most recent compliance
test that demonstrated that the facility was in compliance.
(4) The following additional
records shall be maintained for facilities using catalytic incinerators:
(A) Continuous records of the temperature of
the gas stream both upstream and downstream of the catalyst bed of the
incinerator.
(B) Records of all
three (3) hour periods of operation for which the average temperature measured
at the process vent stream immediately before the catalyst bed is more than
fifty degrees Fahrenheit (50°F) below the average temperature of the
process vent stream which existed during the most recent compliance test that
demonstrated that the facility was in compliance.
(C) Records of all three (3) hour periods of
operation for which the average temperature difference across the catalyst bed
is less than eighty percent (80%) of the temperature difference measured during
the most recent compliance test that demonstrated that the facility was in
compliance.
(5) The
following additional records shall be maintained for facilities using carbon
adsorbers:
(A) Continuous records of the VOC
concentration level or reading in the exhaust stream of the carbon
adsorber.
(B) Records of all three
(3) hour periods of operation during which the average VOC concentration level
or reading in the exhaust gas is more than twenty percent (20%) greater than
the average exhaust gas concentration level or reading measured by the organic
monitoring device during the most recent determination of the recovery
efficiency of the carbon adsorber that demonstrated that the facility was in
compliance.
(6)
Facilities using VOC recovery devices other than carbon adsorbers shall
maintain the monitoring records and meet the reporting requirements specified
by subsection (a)(4).
(7)
Information requirements in subdivisions (3)(B), (4)(B), (4)(C), and (5)(B)
shall be submitted to the department within thirty (30) days of occurrence. The
following information shall accompany the submittal:
(A) The name and location of the
facility.
(B) Identification of the
control system where the excess emission occurred and the facility it
served.
(C) The time, date, and
duration of the exceedance.
(D)
Corrective action taken.
