Sec. 7.
(a) Every
owner or operator of a unit operation or batch process train that is exempt
from the control requirements in section 1(c)(2)(A) or 1(c)(2)(B) of this rule
shall keep records of the uncontrolled total annual mass emissions for such
unit operation or batch process train, as applicable, and documentation
verifying these values or measurements. The documentation shall include the
engineering calculations, any measurements made in accordance with section 5 of
this rule, and the potential or permitted number of batch cycles per year or,
in the alternative, total production as represented in the permit pertaining to
the unit operation or batch process train.
(b) Every owner or operator of a unit
operation or batch process train that is exempt from control requirements of
section 1(c)(2) of this rule shall keep the following records:
(1) The uncontrolled total annual mass
emissions and documentation verifying these values or measurements. The
documentation shall include any engineering calculations, any measurements made
in accordance with section 5 of this rule, and the potential or permitted
number of batch cycles per year or, in the alternative, total production as
represented in the permit pertaining to the unit operation or batch process
train.
(2) The average flow rate in
scfm and documentation verifying this value.
(3) The calculated weighted average
volatility and documentation verifying this value.
(4) The calculated applicability flow rate
value from section 1(e)(3) of this rule.
(c) Every owner or operator of a batch
process train or unit operation subject to the control requirements of section
3 of this rule shall keep records of the following parameters required to be
monitored under section 6 of this rule:
(1) If
using a thermal or catalytic incinerator to comply with section 3 of this rule,
records indicating the average combustion chamber 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 compliance test that demonstrated compliance.
(2) If using a flare, either steam-assisted,
air-assisted, or nonassisted, to comply with section 3 of this rule, continuous
records of the flare pilot flame monitoring and records of all periods of
operations during which the pilot flame is absent.
(3) If using any of the following as a
control device, the following records:
(A)
Where a scrubber is used, the exit specific gravity (or alternative parameter
equivalent in ability to measure the degree of absorbing liquid saturation, if
approved by the commissioner) and the average exit temperature of the absorbing
liquid, measured continuously and averaged over the same time period as the
compliance test that demonstrated compliance (both measured while the vent
stream is routed normally).
(B)
Where a condenser is used, the average exit (product side) temperature measured
continuously and averaged over the same time period as the compliance test that
demonstrated compliance while the vent stream is routed normally.
(C) Where a carbon adsorber is used, the
total steam mass flow measured continuously and averaged over the same time
period as the compliance test that demonstrated compliance (full carbon bed
cycle), temperature of the carbon bed after regeneration (and within fifteen
(15) minutes after completion of any cooling cycle or cycles), and duration of
the carbon bed steaming cycle (all measured while the vent stream is routed
normally).
(D) As an alternative to
clause (A), (B), or (C), at a minimum, records indicating the concentration
level or reading indicated by the VOC monitoring device at the outlet of the
scrubber, condenser, or carbon adsorber, measured continuously and averaged
over the same time period as the compliance test that demonstrated compliance
(while the vent stream is routed normally).
(d) Every owner or operator of a unit
operation claiming a vent stream concentration exemption level, as set forth in
section 1(d)(1) of this rule, shall:
(1)
maintain records to indicate the vent stream concentration is less than or
equal to five hundred (500) ppmv; and
(2) notify the commissioner in writing if the
vent stream concentration at any time equals or exceeds five hundred (500)
ppmv, within sixty (60) days after the event.
The notification shall include a copy of all records of the
event.
(e) An
owner or operator of a batch process train or unit operation subject to the
control requirements of section 3 of this rule may maintain alternative records
other than those listed in section 1 of this rule. Any alternative record
keeping shall be:
(1) approved by the
commissioner and U.S. EPA in writing; and
(2) contained in the permit pertaining to the
batch process train or unit operation as federally enforceable permit
conditions.
(f) The
owner or operator of a unit operation or batch process train that is exempt
from the control requirements of section 3 of this rule shall notify the
commissioner in writing if the uncontrolled total annual mass emissions from
such unit operation or batch process train exceed the threshold in section
1(c)(2)(A) or 1(c)(2)(B) of this rule, respectively, within sixty (60) days
after the event occurs. The notification shall include a copy of all records of
the event.
(g) Every owner or
operator of a batch process train or unit operation required to keep records
under this rule shall:
(1) maintain the
records at the source for a minimum period of five (5) years; and
(2) make the records available to the
commissioner upon request.
