Current through Register Vol. 48, No. 38, September 20, 2024
a) Every owner or operator of a reactor or
distillation unit with a TRE index value of 4.0 or less shall keep records, for
a minimum of 3 years, of the following parameters measured during a performance
test or TRE determination required under Section
218.433
of this Subpart, and required to be monitored under Section
218.434
of this Subpart.
1) Every owner or operator
of a source that seeks to demonstrate compliance with Section
218.432(a)(1)
of this Subpart through the use of either a thermal or catalytic incinerator
shall maintain records of the following:
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 15 minutes and averaged over the same time period of
the performance testing; and
B) The
percent reduction of VOM determined as specified in Section
218.433(c)
of this Subpart achieved by the incinerator, or the concentration of VOM (ppmv,
by compound) determined as specified in Section
218.433(c)
of this Subpart at the outlet of the control device, on a dry basis, corrected
to 3 percent oxygen.
2)
Every owner or operator of a source that seeks to demonstrate compliance with
Section
218.432(a)(1)
of this Subpart through the use of a boiler or process heater shall maintain
the records described below. Any boiler or process heater in which all vent
streams are introduced with primary fuel are exempt from these requirements.
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 44
megawatt measured at least every 15 minutes and averaged over the same time
period of the performance testing.
3) Every owner or operator of a source that
seeks to demonstrate compliance with Section
218.432(a)(2)
of this Subpart through use of a smokeless flare, or flare design (i.e.,
steam-assisted, air-assisted, or nonassisted), shall maintain records of 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) Every owner or operator of a source that
seeks to demonstrate compliance with Section
218.432(b)
of this Subpart shall maintain records of the following:
A) 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 Agency and USEPA, and average exit temperature of the absorbing
liquid measured at least every 15 minutes and averaged over the same time
period as the performance testing (both measured while the vent stream is
normally routed and constituted);
B) Where a condenser is the final recovery
device in the recovery system, the average exit (product side) temperature
measured at least every 15 minutes and averaged over the same time period as
the performance testing while the vent stream is normally routed and
constituted;
C) Where a carbon
absorber is the final recovery device in the recovery system, the total steam
mass or volumetric flow measured at least every 15 minutes and averaged over
the same time period as the performance testing (full carbon bed cycle), the
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 normally routed and
constituted);
D) As an alternative
to subsection (a)(4)(A), (a)(4)(B) or (a)(4)(C) of this Section, the
concentration level or reading indicated by the organic monitoring device at
the outlet of the absorber, condenser, or carbon absorber, measured at least
every 15 minutes and averaged over the same time period as the performance
testing (measured while the vent stream is normally routed and constituted);
or
E) All measurements and
calculations performed to determine the flow rate, VOM concentration, heating
value, and TRE index value of the vent stream.
b) Every owner or operator of a reactor or
distillation unit with a TRE index value of less than 4.0 shall be subject to
the exceedance reporting requirements of the draft Enhanced Monitoring
Guidelines as published at 58 Fed. Reg. 54648 (October 22, 1993).
c) Every owner or operator of a source
seeking to comply with Section
218.432(b)
of this Subpart shall maintain records of the following:
1) Any changes in production capacity,
feedstock type, catalyst type, or of any replacement, removal, or addition of
recovery equipment or reactors and distillation units; and
2) Any recalculation of the flow rate, VOM
concentration, or TRE index value calculated according to subsection (c) of
Appendix G of this Part.
d) Every owner or operator of a source
claiming a design capacity of less than 1 gigagram (1,100 tons) per year, as
contained in Section
218.431(b)
of this Subpart, shall maintain records of the design capacity or any changes
in equipment or operations that may affect the design capacity.
e) Every owner or operator of a source
claiming a vent stream flow rate or vent stream concentration exemption level,
as contained in Section
218.431(b)(5)
of this Subpart, shall maintain records to indicate that the stream flow rate
is less than 0.0085 scm/min or the vent stream concentration is less than 500
ppmv.
