[Comment: For dates and availability of non-regulatory government publications, publications of recognized organizations and associations, federal rules, and federal statutory provisions referenced in this rule, see paragraph (JJ) of rule 3745-21-01 of the Administrative Code titled "referenced materials."]

(A) General provisions.

(1) The methods and procedures of this rule apply to sources governed by rule 3745-21-09 of the Administrative Code.

(2) Use of an alternative test method, in lieu of one of the USEPA's approved test methods or in lieu of other methods specified in this rule, shall be approved by the USEPA as a revision of the state implementation plan.

(3) The results of any compliance testing required by the director for tests conducted pursuant to paragraphs (C) to (F) and (L) of this rule shall not be accepted unless the Ohio EPA district office or local air agency has been notified of the intent to test in accordance with paragraph (A)(4) of this rule not less than thirty days before the proposed initiation of the testing.

(4) Any person notifying the Ohio EPA district office or local air agency of a proposed emissions compliance test shall include as part of the notification the following information:

(a) A statement indicating the purpose of the proposed test and the applicable paragraph of rule 3745-21-09 of the Administrative Code.

(b) A detailed description of the facility to be tested.

(c) A detailed description of the test procedures, equipment and sampling sites.

(d) A timetable, setting forth the dates on which the following will occur:

(i) The testing will be conducted.

(ii) The final test report will be submitted (not later than thirty days after completion of on-site sampling).

(5) For any source compliance determination, the owner or operator of the source shall be responsible for providing the following:

(a) Sampling ports, pipes, lines, or appurtenances for the collection of samples and data required by the test procedures.

(b) Safe access to the sample and data collection locations.

(c) Light, electricity, and other utilities required for sample and data collection.

(B) Method for the determination of volatile organic compound content, solids content, and density of surface coatings and inks.

(1) This method applies to coatings, inks or other coating materials employed in a coating line, printing line or other operation. For purposes of this method "coating" shall also mean "ink" or other coating material.

(2) Any determination of VOC content, solids content, or density of a coating shall be based on the coating as employed (as applied), including the addition of any thinner or viscosity reducer to the coating.

(3) When a sample of a coating is obtained for analysis by any of the procedures described in this method, the amount of the sample shall be at least one quart. The sample shall be placed in an air-tight container. When multiple package coatings are sampled, separate samples of each component shall be obtained.

(4) Using either the procedures set forth in USEPA method 24 (for coatings), USEPA method 24A (for flexographic and rotogravure printing inks and related coatings) and 40 CFR Part 63, Subpart PPPP, Appendix A (for reactive adhesives), or the coating formulation data from the coating manufacturer and coating user, the following shall be determined, where appropriate:

D_C = density of coating, in pounds of coating per gallon of coating.

D_VM = density of volatile matter in coating, in pounds of volatile matter per gallon of volatile matter.

V_S = volume fraction of solids (nonvolatile matter) in coating, in gallon of solids per gallon of coating.

V_VM = volume fraction of volatile matter in coating, in gallon of volatile matter per gallon of coating.

V_W = volume fraction of water in coating, in gallon of water per gallon of coating.

W_S = weight fraction of solids (nonvolatile matter) in coating, in pound of solids per pound of coating.

W_VM = weight fraction of volatile matter in coating, in pound of volatile matter per pound of coating. If this weight fraction is determined by ASTM D2369, "Standard Test Method for Volatile Content of Coatings," the drying conditions shall be one hundred ten degrees Celsius for one hour, except where otherwise authorized by the director based on an alternate analytical procedure that is satisfactorily demonstrated to the director by the coating manufacturer to be more representative of the actual cure mechanism of the coating.

W_W = weight fraction of water in coating, in pound of water per pound of coating.

(5) If the coating contains a volatile matter other than VOC or water, the identity and content of such volatile matter may be determined using either standard gas chromatographic techniques or coating formulation data from the coating manufacturer and coating user. The density of such volatile matter may be determined using either the procedures set forth in ASTM D1475 or data from reference texts. For purposes of this method, such volatile matter shall be referred to as exempt solvent. The following may be determined, where appropriate:

D_ES = density of exempt solvent, in pounds of exempt solvent per gallon of exempt solvent.

V_ES = volume fraction of exempt solvent in coating, in gallon of exempt solvent per gallon of coating.

W_ES = weight fraction of exempt solvent in coating, in pound of exempt solvent per pound of coating.

(6) The weight fraction W_VOC of VOC in a coating and the volume fraction V_VOC of VOC in a coating shall be calculated as follows, where appropriate:

(B) Definitions.

The definitions applicable to this rule are contained in paragraphs (B) and (U) of rule 3745-21-01 of the Administrative Code.

(C) Determination of total uncontrolled potential to emit.

(1) The owner or operator of each commercial bakery oven facility shall calculate the facility's total uncontrolled potential to emit, UPTE(facility), for VOC emissions in tons per year, using either the equations in paragraphs (C)(1)(a) to (C)(1)(c) of this rule and the provisions in paragraphs (C)(2) to (C)(4) of this rule, or a USEPA administrator-approved alternative method if the use of that alternative method is approved in writing by the USEPA administrator for this purpose:

(a) UPTE(facility) equals the sum of the UPTE(oven) for all bakery ovens at the facility (in tons VOC per year)

(b) UPTE(oven) is calculated for each bakery oven as follows:

UPTE(oven) =P_A * EF_VOC * (1 ton/2000 pounds)

where:

P_A = the bakery oven's maximum annual production rate for yeast-leavened finished bakery product (in tons of baked product per year).

EF_VOC = VOC emission factor for the bakery oven's yeast-leavened finished bakery product having the highest emission potential (in pounds of VOC per ton of baked product) for the bakery oven.

(c) The value of EF_VOC, expressed in pounds of VOC per ton of baked product (rounded off to two decimal places), is determined as follows:

EF_VOC = 0.95Y_i + 0.195t_i - 0.51S - 0.86t_s + 1.90

where:

Y_i = initial baker's per cent of yeast to the nearest tenth of a per cent.

t_i = total yeast action time in hours to the nearest tenth of an hour.

S = final (spike) baker's per cent of yeast to the nearest tenth of a per cent.

t_s = spiking time in hours to the nearest tenth of an hour.

(2) The owner or operator shall presume for purposes of calculating the uncontrolled potential to emit that both of the following conditions apply:

(a) Each facility production line and associated bakery oven are operating eight thousand seven hundred sixty hours per year at maximum capacity.

(b) Each facility production line is producing the product with the highest level of VOC emissions of those products that it may produce.

(3) A VOC emission factor based on emission testing can be used to calculate the facility's total uncontrolled potential to emit for VOC in tons per year. In the event emission testing is conducted, the emission testing results would be used instead of the VOC emission factor equation in paragraph (C)(1)(c) of this rule. Such emission testing shall be based on the test methods and procedures specified under paragraph (F) of this rule.

(4) The presumptions of paragraph (C)(2) of this rule would not apply where restrictions on operating hours or annual production rate are specified for the commercial bakery oven facility within a federally enforceable permit-to-install and operate or a Title V permit that is issued pursuant to Chapter 3745-31 or Chapter 3745-77, respectively, of the Administrative Code as follows:

(a) For bakery ovens subject to this rule pursuant to paragraph (A)(1) of this rule and for which installation commenced before May 27, 2005, such restrictions shall be in effect no later than May 27, 2006.

(b) For bakery ovens subject to this rule pursuant to paragraph (A)(1) of this rule and for which installation commenced on or after May 27, 2005, such restrictions shall be in effect upon initial startup of the bakery oven.

(c) For bakery ovens subject to this rule pursuant to paragraph (A)(2) of this rule and for which installation commenced before August 25, 2008, such restrictions shall be in effect no later than August 25, 2009.

(d) For bakery ovens subject to this rule pursuant to paragraph (A)(2) of this rule and for which installation commenced on or after August 25, 2008, such restrictions shall be in effect upon initial startup of the bakery oven.

(e) For bakery ovens subject to this rule pursuant to paragraph (A)(3) of this rule and for which installation commenced before the effective date of this rule, such restrictions shall be in effect no later than one year from the effective date of this rule.

(f) For bakery ovens subject to this rule pursuant to paragraph (A)(3) of this rule and for which installation commenced on or after the effective date of this rule, such restrictions shall be in effect upon initial startup of the bakery oven.

(D) VOC emission control requirements.

(1) Except where exempted under paragraph (D)(2) of this rule, any owner or operator of a commercial bakery oven facility that is subject to this rule shall install and operate a VOC emission control system that reduces the VOC emissions from each bakery oven by at least ninety-five per cent by weight (i.e., an overall control efficiency of at least ninety-five per cent by weight).

(2) Exempted from paragraph (D)(1) of this rule is any uncontrolled bakery oven located in Ashtabula, Butler, Clermont, Hamilton, or Warren counties with annual VOC emissions of less than 25.0 tons and average daily VOC emissions of less than one hundred ninety-two pounds; or any uncontrolled bakery oven located in Cuyahoga, Geauga, Lake, Lorain, Medina, Portage, or Summit counties with annual VOC emissions of less than 10.0 tons and average daily VOC emissions of less than seventy-seven pounds.

(a) The process unit is located in Ashtabula, Butler, Clermont, Cuyahoga, Geauga, Hamilton, Lake, Lorain, Medina, Portage, Summit, or Warren county.

(b) The process unit produces a SOCMI chemical.

(2) Excluded from this rule are the following:

(a) Any reactor or distillation unit that is a batch operation.

(b) Any reactor or distillation unit that is regulated by paragraph (CC) or (EE) of rule 3745-21-09 of the Administrative Code.

(c) Any reactor or distillation unit included within an "early reduction program," as specified in 40 CFR part 63, and published in 57 Federal Register 61970 (December 29, 1992), evidenced by a timely enforceable commitment approved by USEPA.

(d) Any reactor regulated by subpart III or subpart RRR of 40 CFR part 60.

(e) Any distillation unit regulated by subpart NNN of 40 CFR part 60.

(3) For the purposes of paragraph (A)(2) of this rule, a reactor or distillation unit shall be considered regulated by a paragraph, rule or subpart if the reactor or distillation unit is subject to the limits of that paragraph, rule, or subpart. A reactor or distillation unit is not considered regulated by a paragraph, rule, or subpart if the reactor or distillation unit is not subject to the limits of that paragraph, rule, or subpart. For example, if the reactor or distillation unit is covered by an exemption in the paragraph, rule, or subpart, or the applicability criteria of the paragraph or subpart are not met, then the source is not subject to that paragraph, rule, or subpart.

(B) Definitions.

The definitions applicable to this rule are contained in paragraphs (B) and (V) of rule 3745-21-01 of the Administrative Code.

(C) Overall requirements for reactors and distillation units.

(1) Except where exempted under paragraph (C)(2) of this rule, the owner or operator of a reactor or distillation unit subject to this rule shall comply with paragraphs (D) to (L) of this rule.

(2) Exempted from paragraph (C)(1) of this rule is any reactor or distillation unit in a process unit with a total design capacity for all chemicals produced within that unit of less than one thousand one hundred tons per year. However, such reactor or distillation unit remains subject to the recordkeeping and reporting requirements contained in paragraphs (J)(1)(f) and (L)(1) of this rule.

(D) Determination of group status and halogen status for process vents of reactors and distillation units.

(1) (Group status) The owner or operator of a reactor or distillation unit shall determine the group status (i.e., group 1, group 2A, or group 2B) for each process vent based on flow rate, VOC concentration, and TRE index value in accordance with paragraphs (D)(3) to (D)(5) of this rule and the procedures contained in paragraph (E) of this rule. Group 1 process vents require control for VOC, and group 2A and group 2B process vents do not. Group 1 process vents require monitoring of control devices, except for boilers or process heaters specified under paragraphs (F)(1)(b) and (F)(1)(c) of this rule, and require monitoring of bypass lines. Group 2A process vents require monitoring of the associated recovery systems, and group 2B process vents do not require any monitoring.

(2) (Halogen status) The owner or operator of a group 1 process vent which is controlled (or to be controlled) by a combustion device shall determine the halogen status in accordance with the procedures specified in paragraph (E)(7) of this rule. Group 1 process vents that are halogenated process vents being discharged to a combustion device require halogen reduction control (either a pre-combustion or post-combustion).

(3) (Group 1) A process vent shall be group 1 if it meets at least one of the following specifications:

(a) The owner or operator designates the process vent as group 1.

(b) At representative operating conditions expected to yield the lowest TRE index value for the process vent, the TRE index value is less than or equal to 1.0, the flow rate is equal to or greater than 0.30 scfm, and the VOC concentration is equal to or greater than five hundred ppmv.

(4) (Group 2A) A process vent shall be group 2A if it is from a recovery system and if, at representative operating conditions expected to yield the lowest TRE index value for the process vent, the TRE index value is greater than 1.0 and less than or equal to 4.0, the flow rate is equal to or greater than 0.30 scfm, and the VOC concentration is equal to or greater than five hundred ppmv.

(5) (Group 2B) A process vent shall be group 2B if it meets any one of the following specifications:

(a) The process vent has a flow rate less than 0.30 scfm.

(b) The process vent has a VOC concentration less than five hundred ppmv.

(c) The process vent is not from a recovery system and, at representative operating conditions expected to yield the lowest TRE index value for the process vent, the TRE index value is greater than 1.0.

(d) The process vent is from a recovery system and, at representative operating conditions expected to yield the lowest TRE index value for the process vent, the TRE index value is greater than 4.0.

(6) Process changes for group 2A and group 2B process vents.

Whenever process changes are made that could reasonably be expected to change a group 2A or group 2B process vent to a group 1 process vent, the owner or operator shall redetermine the flow rate, VOC concentration, or TRE index value, according to paragraph (D)(6)(a), (D)(6)(b), or (D)(6)(c) of this rule as specified for each process vent as necessary to determine whether the process vent is group 1, group 2A, or group 2B. The owner or operator shall perform the group status determination as soon as practical after the process change and within sixty days after the process change. Examples of process changes include, but are not limited to, changes in production capacity, production rate, feedstock type, or catalyst type, or whenever there is replacement, removal, or addition of recovery equipment. For purposes of paragraph (D)(6) of this rule, process changes do not include process upsets, unintentional, temporary process changes, and changes that are within the range on which the original TRE index value calculation was based.

(a) (Group 2B process vent based on flow rate) The flow rate shall be redetermined by using the measurement procedure in paragraph (E)(9) of this rule or by using an engineering assessment of the effects of the change.

(b) (Group 2B process based on VOC concentration) The VOC concentration shall be redetermined by using the measurement procedure in paragraph (E)(10) of this rule or by using an engineering assessment of the effects of the change.

(c) (Group 2B process vent based on TRE index value or group 2A process vent) The TRE index value shall be redetermined (recalculated) based on measurements of flow rate, net heating value, VOC emission rate, and halogen status as specified in paragraphs (E)(9), (E)(11), (E)(12), and (E)(13) of this rule, or based on an engineering assessment of the effects of the change.

(E) Procedures for process vent determinations.

(1) (General) The provisions under paragraph (E) of this rule provide procedures for the determination of process vent parameters that are used to determine the group status and halogen status for a process vent.

(2) Location within a process vent for determination of group status and halogen status and for sampling.

(a) For the purpose of determining group status of a process vent based on VOC concentration, flow rate, or TRE index value, the location shall be representative of the process vent stream after the last recovery device (if any recovery devices are present) but prior to the inlet of any control device that is present, and prior to release to the atmosphere. The process vent parameters for TRE index value are flow rate, net heating value, VOC emission rate, and halogen status.

(b) The location of the sampling site for measurement of process vent parameters (flow rate, VOC concentration, VOC emission rate, net heating value, and mass emission rate for halogen atoms) shall be selected in accordance with paragraph (E)(2)(a) of this rule and paragraph (C)(3)(f) of rule 3745-21-10 of the Administrative Code. No traverse site selection method is needed for process vents smaller than four inches (0.10 meter) in nominal inside diameter.

(3) The flow rate of a process vent shall be determined by engineering assessment or by the measurement procedure of paragraph (E)(9) of this rule.

(4) The VOC concentration of a process vent shall be determined by engineering assessment or by the measurement procedure of paragraph (E)(10) of this rule.

(5) The net heating value of a process vent shall be determined by engineering assessment or by the measurement procedure of paragraph (E)(11) of this rule.

(6) The VOC and TOC emission rate of a process vent shall be determined by engineering assessment or by the measurement procedure of paragraph (E)(12) of this rule.

(7) The halogen status of a process vent shall be determined by process knowledge that no halogen or hydrogen halides are present in the process vent, by engineering assessment, or by the measurement procedure of paragraph (E)(13) of this rule. If the mass emission rate of halogen atoms for a process vent is equal to or greater than 0.99 pound per hour, the process vent shall be classified as halogenated.

(8) Procedure for TRE index value.

The TRE index value of the process vent shall be determined as follows:

(a) TRE index value for a process vent shall be calculated by the following equation:

TRE = [a + b(Q) + c(H) + d(E_TOC)] / E_VOC

where:

TRE = TRE index value.

Q = Process vent flow rate, standard cubic meters per minute, at a standard temperature of 20 degrees Celsius, as determined under paragraph (E)(3) of this rule by engineering assessment or measurement procedure.

H = Process vent net heating value, megajoules per standard cubic meter, as determined under paragraph (E)(5) of this rule by engineering assessment or measurement procedure.

E_VOC = Process vent emission rate of VOC, kilograms per hour, as determined under paragraph (E)(6) of this rule by engineering assessment or measurement procedure.

E_TOC = Process vent emission rate of TOC, kilograms per hour, as determined under paragraph (E)(6) of this rule by engineering assessment or measurement procedure.

a, b, c, and d = coefficients presented in table A of this rule.

where:

C = Concentration of VOC, dry basis, ppmv.

x = Number of samples in the sample run.

n = Number of components in the sample.

C_ji = Concentration of sample component j of the sample i, dry basis, ppmv.

The emission rates for the preceding calendar year shall be calculated in a manner consistent with the calendar year baseline emissions inventory.

(c) All representations in control plans and annual reports become enforceable conditions. It shall be unlawful for any person to vary from such representations if the variation will cause a change in the identity of the specific emission sources being controlled or the method of control of emissions unless the owner or operator submits a revised control plan to the director and the appropriate Ohio EPA district office or local air agency no later than thirty days after the change. All control plans and reports shall include documentation that the overall reduction of VOC emissions at the account from wastewater from affected source categories continues to be at least ninety per cent less than the calendar year baseline emissions inventory.

(I) Determination of wastewater characteristics.

The determination of the characteristics of a wastewater stream for purposes of this rule shall be made as follows:

(1) The characteristics shall be determined at a location between the point of generation (as defined by this rule) and before the wastewater stream is exposed to the atmosphere, treated for VOC removal, or mixed with another wastewater stream. For wastewater streams which, prior to the date the faclity became subject to this rule, were either actually being mixed or construction had commenced which would result in the wastewater streams being mixed, this mixing shall not establish a limit on where the characteristics may be determined.

(2) The flow rate of a wastewater stream shall be determined on the basis of an annual average by one of the following methods:

(a) The highest annual quantity of wastewater managed, based on historical records for the most recent five years of operation, or for the entire time the wastewater stream has existed if less than five years, but at least one year.

(b) The maximum design capacity of the waste management unit.

(c) The maximum design capacity to generate wastewater of the process unit generating the wastewater stream.

(d) Measurements that are representative of the actual, normal wastewater generation rates.

(3) The VOC concentration of a wastewater stream shall be determined on the basis of a flow-weighted annual average by one of the following methods, or by a combination of the methods. If the director or USEPA determines that the VOC concentration cannot be adequately determined by knowledge of the wastewater, or by bench-scale or pilot-scale test data, the VOC concentration shall be determined in accordance with paragraph (I)(3)(c) of this rule, or by a combination of the methods in paragraphs (I)(3)(a) to (I)(3)(c) of this rule. VOC with a "Henry's Law Constant" less than 1.8x10^-6 atmosphere-cubic meter/mole (0.1 y/x) at twenty-five degrees Celsius shall not be included in the determination of VOC concentration.

(a) (Knowledge of the wastewater) Sufficient information to document the VOC concentration. Examples of information include material balances, records of chemical purchases, or previous test results.

(b) (Bench-scale or pilot-scale test data) Sufficient information to demonstrate that the bench-scale or pilot-scale test concentration data are representative of the actual VOC concentration.

(c) (Measurements) Collect a minimum of three representative samples from the wastewater stream and determine the affected VOC concentration for each sample in accordance with paragraph (G) of this rule (relating to approved test methods). The affected VOC concentration of the wastewater stream shall be the flow-weighted average of the individual samples.

(4) The annual affected VOC loading in wastewater for a wastewater stream shall be the annual average flow rate determined in paragraph (I)(2) of this rule multiplied by the annual average affected VOC concentration determined in paragraph (I)(3) of this rule.

(5) The annual VOC loading in wastewater for a plant shall be the sum of the annual VOC loading in wastewater for each affected VOC wastewater stream.

(6) The "Henry's Law Constant" shall be determined by the procedures in 40 CFR part 60, appendix J, as proposed on December 9, 1998 in the Federal Register.

(J) Maintenance wastewater.

(a) As specified in paragraph (C)(3)(h)(iv) of this rule at least every five years.

(b) At least once every twelve months as specified in paragraph (C)(3)(h)(ii) of this rule.

(iv) Visually inspect the internal floating roof, the primary seal, the secondary seal (if one is in service), gaskets, slotted membranes and sleeve seals (if any) each time the storage vessel is emptied and degassed. If the internal floating roof has defects, the primary seal has holes, tears, or other openings in the seal or the seal fabric, or the secondary seal has holes, tears, or other openings in the seal or the seal fabric, or the gaskets no longer close off the liquid surfaces from the atmosphere, or the slotted membrane has more than ten per cent open area, the owner or operator shall repair the items as necessary so that none of the conditions specified in this paragraph exist before refilling the storage vessel with a volatile organic liquid. In no event shall inspections conducted in accordance with this provision occur at intervals greater than ten years in the case of vessels conducting the annual visual inspection as specified in paragraphs (C)(3)(h)(ii) and (C)(3)(h)(iii)(b) of this rule and at intervals no greater than five years in the case of vessels specified in paragraph (C)(3)(h)(iii)(a) of this rule.

(i) Notify the director in writing at least thirty days prior to the filling or refilling of each storage vessel for which an inspection is required by paragraphs (C)(3)(h)(i) and (C)(3)(h)(iv) of this rule to afford the director or the director's authorized designee the opportunity to have an observer present. If the inspection required by paragraph (C)(3)(h)(iv) of this rule is not planned and the owner or operator could not have known about the inspection thirty days in advance of refilling the tank, the owner or operator shall notify the director at least seven days prior to the refilling of the storage vessel. Notification shall be made by telephone immediately followed by written documentation demonstrating why the inspection was unplanned. Alternatively, this notification including the written documentation may be made in writing and sent by express mail so that it is received by the director at least seven days prior to the refilling.

(j) Recordkeeping and reporting.

The owner or operator of each storage vessel equipped with an internal floating roof shall keep records and furnish reports in accordance with the following:
