operator subject to the provisions of this rule shall keep up-to-date
continuous records of the flare pilot flame monitoring specified in
Subparagraph (4)(b) of this rule as well as up-to-date records of all periods
of operations in which the pilot flame is absent.
(i) Each owner or operator subject to the
provisions of this rule shall keep up-to-date continuous records of the
equipment operating parameters specified to be monitored under Subparagraph
(4)(c) of this rule as well as up-to-date records of periods of operation
during which the parameter boundaries established during the most recent
compliance test are exceeded. The Technical Secretary may at any time require a
report of these data. Where the owner or operator seeks to demonstrate
compliance with Subparagraph (3)(c) of this rule, periods of operation during
which the parameter boundaries established during the most recent compliance
tests are exceeded and therefore an instance of noncompliance has occurred are
defined as follows:
1. Where an absorber is
the final recovery device in a recovery system, and where an organic monitoring
device is not used:
(i) All 3-hour periods of
operation during which the average absorbing liquid temperature was more than
11°C (20°F) above the average absorbing liquid temperature during the most
recent compliance test that demonstrated that the facility was in compliance,
or
(ii) All 3-hour periods of
operation during which the average absorbing liquid specific gravity was more
than 0.1 unit above, or more than 0.1 unit below, the average absorbing liquid
specific gravity during the most recent compliance test that demonstrated that
the facility was in compliance.
2. Where a condenser is the final recovery
device in a recovery system, and where an organic monitoring device is not
used, all 3-hour periods of operation during which the average exit (product
site) condenser operating temperature was more than 6°C (11°C) above the
average exit (product site) operating temperature during the most recent
compliance test that demonstrated that the facility was in
compliance.
3. Where a carbon
adsorber is the final recovery device in a recovery system and where an organic
monitoring device is not used:
(i) All carbon
bed regeneration cycles during which the total mass steam flow was more than 10
percent below the total mass steam flow during the most recent compliance test
that demonstrated that the facility was in compliance, or
(ii) All carbon bed regeneration cycles
during which the temperature of the carbon bed after regeneration [and after
completion of any cooling cycle(s)] was more than 10 percent greater than the
carbon bed temperature (in degrees Celsius) during the most recent compliance
test that demonstrated that the facility was in compliance.
4. Where an absorber, condenser,
or carbon adsorber is the final recovery device in the recovery system and an
organic monitoring device approved by the Technical Secretary is used, all
3-hour periods of operation during which the average concentration level or
reading of organic compounds in the exhaust gases is more than 20 percent
greater than the exhaust gas organic compound concentration level or reading
measured by the monitoring device during the most recent compliance test that
demonstrated that the facility was in compliance.
(j) Each owner or operator subject to the
provisions of this rule and seeking to demonstrate compliance with Subparagraph
(3)(c) of this rule shall keep up-to-date records of:
1. Any changes in production capacity,
feedstock type, or catalyst type, or of any replacement, removal, or addition
of recovery equipment or air oxidation reactors;
2. Any calculation of the TRE index value
performed pursuant to Subparagraph (5)(b) of this rule.
3. The results of any test performed pursuant
to the methods and procedures required by Subparagraph (4)(d) of this
rule.
