The owner or operator of each batch process operation in the
Beaumont-Port Arthur, Bexar County, and Houston-Galveston-Brazoria
areas shall maintain the following information for at least five years
at the plant, as defined by its air quality account number, except
that the five-year record retention requirement does not apply to
records generated before December 31, 2000. The owner or operator
shall make the information available upon request to representatives
of the executive director, EPA, or any local air pollution control
agency having jurisdiction in the area:
(1) Vapor control systems. For vapor control systems
used to control emissions from batch process operations, records of
appropriate parameters to demonstrate compliance, including:
(A) continuous monitoring and recording of:
(i) for a direct-flame incinerator, the exhaust gas
temperature in the firebox or in the ductwork immediately downstream
of the firebox before any substantial heat exchange. The temperature
monitoring device shall have an accuracy of ±0.5 degrees Celsius,
or alternatively, ±1.0%;
(ii) for a catalytic incinerator, the exhaust gas temperature
immediately before and after the catalyst bed. The temperature monitoring
device shall have an accuracy of ±0.5 degrees Celsius, or alternatively, ±1.0%;
(iii) for an absorber, either:
(I) the scrubbing liquid temperature. The temperature
monitoring device shall have an accuracy of ±1.0% of the temperature
being monitored in degrees Celsius, or alternatively, ±0.02
specific gravity unit; or
(II) the concentration level of volatile organic compounds
(VOC) exiting the recovery device based on a detection principle such
as infrared, photoionization, or thermal conductivity;
(iv) for a condenser or refrigeration system, either:
(I) the condenser exit temperature. The temperature
monitoring device shall have an accuracy of ±1.0% of the temperature
being monitored in degrees Celsius, or alternatively, ±0.5
degrees Celsius; or
(II) the concentration level of VOC exiting the recovery
device based on a detection principle such as infrared, photoionization,
or thermal conductivity;
(v) for a carbon adsorption system, as defined in §101.1
of this title (relating to Definitions), either:
(I) steam flow (using an integrating steam flow monitoring
device) and the carbon bed temperature. The steam flow monitor shall
have an accuracy of ±10%. The temperature monitor shall have
an accuracy of ±1.0% of the temperature being monitored in
degrees Celsius, or ±0.5 degrees Celsius, whichever is greater;
or
(II) the concentration level of VOC exiting the recovery
device based on a detection principle such as infrared, photoionization,
or thermal conductivity;
(vi) for a pressure swing adsorption unit that is the
final recovery device, the temperature of the bed near the inlet and
near the outlet. The temperature monitoring device shall have an accuracy
of ±1.0% of the temperature being monitored in degrees Celsius,
or ±0.5 degrees Celsius; and
(vii) for a vapor combustor, the exhaust gas temperature
in the firebox or in the ductwork immediately downstream of the firebox
before any substantial heat exchange. The temperature monitoring device
shall have an accuracy of ±0.5 degrees Celsius, or alternatively, ±1.0%.
Alternatively, the owner or operator of a vapor combustor may consider
the unit to be a flare and meet the requirements of subparagraph (B)
of this paragraph;
(B) for flares, the requirements specified in 40 Code
of Federal Regulations §60.18(b) and Chapter 111 of this title
(relating to Control of Air Pollution from Visible Emissions and Particulate
Matter); and
(C) for vapor control systems other than those specified
in subparagraphs (A) and (B) of this paragraph, records of appropriate
operating parameters.
(2) Process vents. A record of the following emission
stream parameters for each process vent contained in the batch process:
(A) the annual mass emission total and documentation
verifying these values. If emission estimate equations are used, the
documentation shall be the calculations coupled with the expected
or permitted (if available) number of emission events per year; and
(B) the average flow rate in standard cubic feet per
minute and documentation verifying these values.
(3) Performance test monitoring parameters. Records
of the following parameters required to be measured during a performance
test required under §115.165 of this title (relating to Approved
Test Methods and Testing Requirements) and required to be monitored
under paragraph (1) of this section:
(A) where an owner or operator seeks to demonstrate
compliance with §115.162 of this title (relating to Control Requirements)
through use of either a direct-flame or catalytic incinerator, the
average firebox temperature of the incinerator (or the average temperature
upstream and downstream of the catalyst bed for a catalytic incinerator),
measured continuously and averaged over the same time period as the
performance test;
(B) where an owner or operator seeks to demonstrate
compliance with §115.162 of this title through use of a smokeless
flare, the flare design (i.e., steam-assisted, air-assisted, or nonassisted),
all visible emissions readings, heat content determinations, flow
rate measurements, and exit velocity determinations made during the
performance test; continuous flare pilot flame monitoring; and all
periods of operations during which the pilot flame is absent; and
(C) where an owner or operator seeks to demonstrate
compliance with §115.162 of this title:
(i) with an absorber as the final control device, the
exit specific gravity (or alternative parameter which is a measure
of the degree of absorbing liquid saturation, if approved by the executive
director) and average exit temperature of the absorbing liquid measured
continuously and averaged over the same time period as the performance
test (both measured while the vent stream is routed normally);
(ii) with a condenser as the control device, the average
exit (product side) temperature measured continuously and averaged
over the same time period as the performance test while the vent stream
is routed normally;
(iii) with a carbon adsorption system as the control
device, the total steam mass flow measured continuously and averaged
over the same time period as the performance test (full carbon bed
cycle), temperature of the carbon bed after regeneration (and within
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 normally);
(iv) the concentration level or reading indicated by
an organic monitoring device at the outlet of the absorber, condenser,
or carbon adsorption system, measured continuously and averaged over
the same time period as the performance test while the vent stream
is routed normally; and
(v) with a pressure swing adsorption unit as the final
recovery device, the temperature of the bed near the inlet and near
the outlet. The temperature monitoring device shall have an accuracy
of ±1.0% of the temperature being monitored in degrees Celsius,
or ±0.5 degrees Celsius.
