Temporarily adds new provisions to address volatile organic compounds (VOC) reasonably available control technology (RACT) in Lake County and Porter County for process vents in batch operations. Authority:
IC 4-22-2-37.1(a)(13). Effective September 3, 2009.
SECTION 1. Applicability. (a) This document 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 document.
(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 document with the following exceptions:
(1) Any source subject to control requirements in 326 IAC 8-5-3 is not subject to this document.
(2) The following unit operations within a batch process train and batch process trains are exempt from SECTION 3 of this document, control requirements, but are subject to SECTION 7 of this document, record keeping, and SECTION 8 of this document, 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 document, 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 document. 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 document, 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 326 IAC 8 regulating the source category.
SECTION 2. Definitions. The following definitions apply throughout this document:
(1) "Aggregate" means the summation of all process vents containing VOC within a process.
(2) "Batch cycle" means a manufacturing event of an intermediate or product from start to finish in a batch process train.
(3) "Batch operation" means a noncontinuous operation in which a discrete quantity or batch of feed is charged into a unit operation within a batch process train and processed at one (1) time. Batch operation includes noncontinuous operations in which the equipment is fed intermittently or discontinuously. Addition of raw material and withdrawal of product do not occur simultaneously in a batch operation. After each batch operation, the equipment is generally emptied before a fresh batch is started.
(4) "Batch process train" means the collection of equipment, such as:
(A) reactors;
(B) filters;
(C) dryers;
(D) distillation columns;
(E) extractors;
(F) crystallizers;
(G) blend tanks;
(H) neutralizer tanks;
(I) digesters;
(J) surge tanks; and
(K) product separators;
configured to produce a specific product or intermediate by a batch operation. A batch process train terminates at the point of storage or product handling of the product or intermediate being produced in the batch process train. Irrespective of the product being produced, a batch process train that is independent of other processes shall be considered a single batch process train for purposes of this document.
(5) "Boiler" means any enclosed combustion device that extracts useful energy in the form of steam.
(6) "Btu" means British thermal unit.
(7) "Continuous recorder" means a data recording device that either records:
(A) an instantaneous data value at least once every fifteen (15) minutes; or
(B) fifteen (15) minute or more frequent block average values.
(8) "Control device" means any device or combination of devices designed to recover or destroy VOC vapors received from the process vents. A recovery device that is a required part of the process, for example, but not limited to, condensers operating under reflux conditions, is not a control device.
(9) "Emission event" means a discrete period of venting that is associated with a unit operation. For example, a displacement of vapor resulting from the charging of a unit operation with VOC will result in a discrete emission event that will last through the duration of the charge and will have an average flow rate equal to the rate of the charge. The expulsion of expanded unit operation vapor space when the vessel is heated is also an emission event. Both of these examples of emission events and others may occur in the same unit operation during the course of the batch cycle. If the flow rate measurement for any discrete period of venting is zero (0), then the event is not an emission event for purposes of this document.
(10) "Flame zone" means the portion of the combustion chamber in a boiler occupied by the flame envelope.
(11) "Incinerator" means any enclosed combustion device that is used for destroying organic compounds. Auxiliary fuel may be used to heat waste gas to combustion temperatures. Any energy recovery section present is not physically formed into one (1) section; rather, the energy recovery system is a separate section following the combustion section and the two are joined by ducting or connections that carry fuel gas.
(12) "MmHg" means millimeters of mercury.
(13) "Permit" means a permit issued by the commissioner under 326 IAC 2.
(14) "Ppmv" means parts per million by volume.
(15) "Process vent" means a vent gas stream that is discharged from a unit operation or multiple unit operations within the same batch process train that are manifolded together into a common header. A process vent begins at the inlet to the control device prior to mixing with vent gas streams from other process trains or unrelated operations or, in the absence of a control device, at the point of discharge to the atmosphere. The term does not include exhaust streams from exhaust hood and building ventilation fans that are used to provide ventilation for workers and not to collect and discharge emissions from specific unit operations. Process vents exclude the following:
(A) Relief valve discharges.
(B) Leaks from equipment.
(C) Vents from storage tanks.
(D) Vents from transfer or loading operations.
(E) Vents from wastewater.
(16) "Recovery device" means an individual unit of equipment, such as:
(A) an absorber;
(B) a carbon adsorber; or
(C) a condenser;
capable of and used for the purpose of recovering chemicals for use, reuse, or sale.
(17) "Recovery system" means an individual recovery device or series of such devices applied to the same vent stream.
(18) "Scfm" means standard cubic feet per minute.
(19) "Standard industrial classification code" or "SIC code" means a series of four (4) digit codes devised by the Office of Management and Budget (OMB) of the federal government to classify establishments according to the type of economic activity in which they are engaged.
(20) "Unit operation" means one (1) or more pieces of process equipment used to make a single change to the physical or chemical characteristics of one (1) or more process streams. Equipment used for these purposes includes, but is not limited to, the following:
(A) Reactors.
(B) Filters.
(C) Dryers.
(D) Distillation columns.
(E) Extractors.
(F) Crystallizers.

The owner or operator shall, at its own expense, conduct the tests in accordance with the applicable test methods and procedures specified in subsections (d), (e), and (f).
(b) Notwithstanding subsection (a), flares and process boilers used to comply with the control requirements of SECTION 3 of this document shall be exempt from compliance testing requirements.
(c) When a flare is used to comply with the control requirements of SECTION 3 of this document, the flare shall comply with the requirements of 40 CFR 60.18*.

(1) an average flow rate that is equal to or above the calculated applicability flow rate; or
(2) a VOC concentration of less than or equal to five hundred (500) ppmv (unit operation);
shall demonstrate, upon the commissioner's request, the absence of oversized gas moving equipment in any manifold. Gas moving equipment shall be considered oversized if it exceeds the maximum requirements of the exhaust flow rate by more than thirty percent (30%).
(e) For the purpose of demonstrating compliance with the control requirements in SECTION 3 of this document, the batch process train or unit operation shall be run at representative operating conditions and flow rates during any compliance test.
(f) The following methods in 40 CFR 60, Appendix A* shall be used to demonstrate compliance with the reduction efficiency requirement set forth in SECTION 3 of this document:

The control device inlet sampling site for determination of vent stream VOC composition reduction efficiency shall be prior to the control device and after the control device.
(2) U.S. EPA Method 2, 2A, 2B, 2C, or 2D, as appropriate, for determination of gas stream volumetric flow rate flow measurements, which shall be taken continuously. No traverse is necessary when the flow measuring device is an ultrasonic probe.
(3) U.S. EPA Method 25A or U.S. EPA Method 18, if applicable, to determine the concentration of VOC in the control device inlet and outlet as follows:
(A) The sampling time for each run shall be as follows:
(i) For batch cycles less than eight (8) hours in length, readings shall be taken continuously over the entire length of the batch cycle with a maximum of fifteen (15) minute intervals between measurements if using U.S. EPA Method 25A. If using U.S. EPA Method 18, readings shall be taken continuously with a maximum of fifteen (15) minute intervals between measurements throughout the batch cycle unless it becomes necessary to change the impinger train, in which case a thirty (30) minute interval shall not be exceeded.
(ii) For batch cycles of eight (8) hours and greater in length, the owner or operator may either test in accordance with the test procedures defined in item (i) or the owner or operator may elect to perform tests, pursuant to either U.S. EPA Method 25A or U.S. EPA Method 18, only during those portions of each emission event that define the emission profile of each emission event occurring within the batch cycle. For each emission event of less than four (4) hours in duration, the owner or operator shall test continuously over the entire emission event as set forth in item (i). For each emission event of greater than four (4) hours in duration, the owner or operator shall elect either to perform a minimum of three (3) one (1) hour test runs during the emission event or shall test continuously over the entire emission event within each unit operation in the batch process train. To demonstrate that the portion of the emission event to be tested defines the emission profile for the emission event, the owner or operator electing to rely on this option shall develop an emission profile for the entire emission event. The emission profile shall be based upon either process knowledge or test data collected. Examples of information that could constitute process knowledge include, but are not limited to, calculations based on material balances and process stoichiometry. Previous test results may be used provided the results are still relevant to the current
process vent stream conditions.
(B) The mass emission rate from the process vent or inlet to the control device shall be determined by combining concentration and flow rate measurements taken simultaneously at sampling sites selected in accordance with subdivision (1) throughout the batch cycle.
(C) The mass emission rate from the control device outlet shall be obtained by combining concentration and flow rate measurements taken simultaneously at sampling sites selected in accordance with subdivision (1) throughout the batch cycle.
(D) The efficiency of the control device shall be determined by integrating the mass emission rates obtained in clauses (B) and (C) over the time of the batch cycle and dividing the difference in inlet and outlet mass flow totals by the inlet mass flow total.
(g) The owner or operator of a batch process train or unit operation may propose an alternative test method or procedures to demonstrate compliance with the control requirements set forth in SECTION 3 of this document. The method or procedures shall be:
(1) approved by the commissioner and U.S. EPA in writing; and
