Affected: IC 13-15; IC 13-17
Sec. 1.
(a) This rule
applies to any source that has a batch process train associated with any of the
SIC codes 2821, 2833, 2834, 2861, 2865, 2869, or 2879, and that meets the
following criteria:
(1) Is located in Lake
County or Porter County.
(2) Has
the potential to emit emissions of VOCs greater than or equal to one hundred
(100) tons per year from all of the following:
(A) Process vents from all batch
operations.
(B) All noncontrol
technique guideline (non-CTG) emission units.
(C) Unregulated emissions from CTG emission
units, except emission units regulated under 40 CFR 60, Subpart BBB*; 40 CFR
60, Subpart III*; 40 CFR 60, Subpart NNN*; or 40 CFR 63, Subpart T*.
(b) If a source meets
the applicability requirements under subsection (a), but reduces its potential
to emit for VOCs by means of federally enforceable operational restriction (for
example, production, hours of operation, or capacity utilization) to less than
one hundred (100) tons per year by April 1, 2011, the source is not subject to
the requirements of section 3 of this rule.
(c) The owner or operator of a batch process
train at a source that meets the applicability criteria of subsection (a) is
subject to this rule with the following exceptions:
(1) Any source subject to control
requirements in 326 IAC 8-5-3 is not subject to this rule.
(2) The following unit operations within a
batch process train and batch process trains are exempt from section 3 of this
rule, control requirements, but are subject to section 7 of this rule, record
keeping, and section 8 of this rule, reporting:
(A) Any unit operation with uncontrolled
total annual mass emissions of less than or equal to five hundred (500) pounds
per year of VOC. Such unit operations are also excluded from the calculation of
the total annual mass emissions for a batch process train. If the uncontrolled
total annual mass emissions from such exempt unit operation exceed five hundred
(500) pounds per year of VOC in any subsequent year, the owner or operator
shall calculate and determine applicability in accordance with subsection (d)
for both the individual unit operation and the batch process train containing
the unit operation.
(B) Any batch
process train containing process vents that have, in the aggregate,
uncontrolled total annual mass emissions, as determined in accordance with
section 4(a)(1) of this rule, of less than thirty thousand (30,000) pounds per
year of VOC for all products manufactured in such batch process
train.
(d)
The applicability equations in subsection (e), which require the calculation of
uncontrolled total annual mass emissions and flow rate value, shall be used to
determine whether a unit operation or a batch process train is subject to the
control requirements in section 3 of this rule. The applicability equations
shall be applied to the following:
(1) Any
unit operation with uncontrolled total annual mass emissions that exceed five
hundred (500) pounds per year and with a VOC concentration greater than five
hundred (500) parts per million by volume (ppmv). In this individual
determination, no applicability analysis shall be performed for any unit
operation with a VOC concentration of less than or equal to five hundred (500)
ppmv.
(2) Any batch process train
containing process vents that, in the aggregate, have uncontrolled total annual
mass emissions of thirty thousand (30,000) pounds per year or more of VOC from
all products manufactured in the batch process train. Any unit operation with
uncontrolled total annual mass emissions exceeding five hundred (500) pounds
per year, regardless of VOC concentration, shall be included in the aggregate
applicability analysis.
(e) Applicability equations under this
subsection are specific to volatility and are as follows:
(1) Abbreviations are as follows:
(A) FR = calculated applicability flow rate,
scfm.
(B) UTAME = uncontrolled
total annual mass emissions of VOC, expressed as pounds per year.
(C) WAV = weighted average
volatility.
(D)
MVOCi = mass of VOC component i.
(E) MWVOCi = molecular
weight of VOC component i.
(F)
VPi = vapor pressure of VOC component i.
(G) i = subscript denoting a specific VOC
component.
(H) n = total number of
VOC components.
(2)
Weighted average volatility shall be calculated as follows:

(3) For
purposes of determining applicability, calculated applicability flow rate
values shall be determined as follows:
(A)
Process vents with a WAV that is less than or equal to seventy-five (75) mmHg
at twenty (20) degrees Celsius (sixty-eight (68) degrees Fahrenheit), shall use
the following equation:
FR = [0.07 (UTAME)] - 1,821
(B) Process vents with a WAV that is greater
than seventy-five (75) mmHg, but less than or equal to one hundred fifty (150)
mmHg at twenty (20) degrees Celsius (sixty-eight (68) degrees Fahrenheit),
shall use the following equation:
FR = [0.031 (UTAME)] - 494
(C) Process vents with a WAV that is greater
than one hundred fifty (150) mmHg at twenty (20) degrees Celsius (sixty-eight
(68) degrees Fahrenheit), shall use the following equation:
FR = [0.013 (UTAME)] - 301
(f) For purposes of subsection
(a), an emission unit shall be considered regulated by a rule, section, or
subpart if it is subject to the limits of that rule, section, or subpart. An
emission unit is not considered regulated by a rule, section, or subpart if it
is not subject to the limits of that rule, section, or subpart. For example, if
the emission unit is covered by an exemption in the rule, section, or subpart,
or the applicability criteria of the rule, section, or subpart are not met,
then the source is not subject to rule, section, or subpart. An emission unit
is also not considered regulated if there is no rule contained in this article
regulating the source category.
