§115.160.  Batch Process Definitions.
As adopted by TNRCC October 27, 1999, effective November 18, 1999

     The following words and terms, when used in this division, shall have the following meanings, unless the context clearly indicates otherwise.  Additional definitions for terms used in this division are found in §115.10 of this title (relating to Definitions), §101.1 of this title (relating to Definitions), and §3.2 of this title (relating to Definitions).

          (1)  Aggregated - The summation of all process vents containing volatile organic compounds (VOC) within a process.

          (2)  Annual mass emissions total - The sum of all VOC emissions (pounds per year), evaluated before control but after the last recovery device, from a process vent.  Annual mass emissions shall be calculated from an individual process vent or groups of process vents by using emission estimation equations contained in Chapter 3 of EPA's Control of Volatile Organic Compound Emissions from Batch Processes - Alternative Control Techniques Information Document (EPA-453/R-94-020, February 1994) and then multiplying by the historical duration and frequency of the emission or groups of emissions over the course of a year.  For process vents that are included in a new source review air permit, standard permit, or exemption from permitting registered by Form PI-8, the annual mass emissions total shall be based on the maximum allowable emission rate (MAER) levels in the permit or Form PI-8 (adjusted to represent the level before control, but after the last recovery device), whether they correspond to the maximum design production potential or to the actual annual production estimate.

          (3)  Average flow rate - The flow rate in standard cubic feet per minute (scfm) averaged over the amount of time that VOCs are emitted during an emission event.  For the evaluation of average flow rate from an aggregate of sources, the average flow rate is the weighted average of the average flow rates of the emission events and their annual venting time, or: 


                     Summation (F)(D)
Average flow rate = -----------------
                      Summation (D) 

where:
          F = Average flow rate per emission event

          D = Annual duration of emission event

          (4)  Batch - A noncontinuous process involving the bulk movement of material through sequential manufacturing steps.  Mass, temperature, concentration, and other properties of a system vary with time.  Batch processes are not characterized by steady-state conditions.  Reactants are not added and products are not removed simultaneously.

          (5)  Batch cycle - A manufacturing event of an intermediate or product from start to finish in a batch process.

          (6)  Batch process (for the purpose of determining RACT applicability) - The batch equipment assembled and connected by pipes, or otherwise operated in a sequence of steps, to manufacture a product in a batch fashion.

          (7)  Batch process train - An equipment train that is used to produce a product or intermediates in batch fashion.  A typical equipment train consists of equipment used for the synthesis, mixing, and purification of a material.

          (8)  Emissions before control - The emissions total before the application of a control device but after the last recovery device, or the emissions total if no control device is used.  The emissions total may not be reduced to account for discharge of VOC into wastewater if the wastewater is further handled or processed with the potential for VOC emissions to the atmosphere.

          (9)  Primary fuel - The fuel that provides the principal heat input to a device.  To be considered a primary fuel, the fuel must be able to sustain operation without the addition of other fuels.

          (10)  Process vent - A vent gas stream that is discharged from a batch process.  Process vents include gas streams that are discharged directly to the atmosphere or are discharged to the atmosphere after diversion through a recovery device.  Process vents exclude relief valve discharges, leaks from equipment, vents from storage tanks, vents from transfer/loading operations, and vents from wastewater.  Process gaseous streams that are used as primary fuels are also excluded.  The lines that transfer such fuels to a plant fuel gas system are not considered to be vents.

          (11)  RACT - Reasonably available control technology.

          (12)  Recovery device - An individual unit of equipment capable of and used for recovering chemicals for use, reuse, or sale.  Recovery devices include, but are not limited to, absorbers, carbon adsorbers, and condensers.
          (13)  Semi-continuous - Conduction of operations on a steady-state mode but only for finite durations (in excess of eight hours minimum) during the course of a year.  For example, a steady-state distillation operation that functions for one month would be considered semi-continuous.

          (14)  Unit operations - Those discrete processing steps that occur within distinct equipment that are used to prepare reactants, facilitate reactions, separate and purify products, and recycle materials.

          (15)  Volatility - As follows.

               (A)  Low volatility VOCs are those which have a vapor pressure less than or equal to 75 millimeters of mercury (mmHg) at 20 degrees Celsius.

               (B)  Moderate volatility VOCs are those which have a vapor pressure greater than 75 and less than or equal to 150 mmHg at 20 degrees Celsius.

               (C)  High volatility VOCs are those which have a vapor pressure greater than 150 mmHg at 20 degrees Celsius.

               (D)  To evaluate VOC volatility for single unit operations that service numerous VOCs or for processes handling multiple VOCs, the weighted average volatility can be calculated from the total amount of each VOC emitted in a year and the individual component vapor pressure, as follows: 

                                 Summation Vpi x (Mi / MWi)
Weighted average volatility  =  ---------------------------
                                   Summation (Mi / MWi )

where:

          Vpi = Vapor pressure of VOC component i
          Mi = Mass of VOC component i
          MWi = Molecular weight of VOC component i

§115.161.  Applicability.
As adopted by TNRCC October 27, 1999, effective November 18, 1999

     (a)  The provisions of §§115.162-115.167 of this title (relating to Control Requirements; Alternate Control Requirements; Determination of Emissions and Flow Rates; Approved Test Methods and Testing Requirements; Monitoring and Recordkeeping Requirements; and Exemptions) apply to vent gas streams at batch process operations in the Beaumont/Port Arthur area, as defined in §115.10 of this title (relating to Definitions), under the following Standard Industrial Classification (SIC) codes:

          (1)  2821 (plastic resins and materials);
          (2)  2833 (medicinals and botanicals);
          (3)  2834 (pharmaceutical preparations);
          (4)  2861 (gum and wood chemicals);
          (5)  2865 (cyclic crudes and intermediates);
          (6)  2869 (industrial organic chemicals, not elsewhere classified); and
          (7)  2879 (agricultural chemicals, not elsewhere classified).

     (b)  Any batch process operation that is exempt under §115.167(1) of this title (relating to Exemptions) is subject to the requirements of Division 2 of this subchapter (relating to Vent Gas Control).

***********************end tx 115.161 a9xt**********************eb2k***b2n**

§115.162.  Control Requirements.
As adopted by TNRCC October 27, 1999, effective November 18, 1999

     The owner or operator of each batch process operation in the Beaumont/Port Arthur area shall comply with the following control requirements.

          (1)  Reasonable available control technology (RACT) equations.  The volatile organic compounds (VOC) mass emission rate from individual process vents or for process vent streams in aggregate within a batch process shall be reduced by 90% if the actual average flow rate value (in standard cubic feet per minute (scfm)) is below the flow rate (FR) value calculated using the applicable RACT equation for the volatility range (low, moderate, or high) of the material being emitted when the annual mass emission total (AE, in pounds per year) are input.  The RACT equations, specific to volatility, are as follows:

               (A)  Low volatility:  FR = 0.07(AE) - 1821;

               (B)  Moderate volatility:  FR = 0.031(AE) - 494;

               (C)  High volatility:  FR = 0.013(AE) - 301.

          (2)  Successive ranking scheme.  For aggregate streams within a process, the control requirements must be evaluated with the following successive ranking scheme until control of a segment of unit operations is required or until all unit operations have been eliminated from the process pool.

               (A)  If, for the process vent streams in aggregate, the value of FR calculated using the applicable RACT equation in paragraph (1) of this section is negative (i.e., less than zero), then the process is exempt from the 90% control requirements, and the successive ranking scheme of subparagraph (F) of this paragraph does not apply.  This would occur if the mass annual emission rates are below the lower limits specified in §115.167(2)(A) of this title (relating to Exemptions).

               (B)  If, for the process vent streams in aggregate, the actual average flow rate value (in scfm) is below the value of FR calculated using the applicable RACT equation in paragraph (1) of this section, then the overall emissions from the batch process must be reduced by 90%, and the successive ranking scheme of subparagraph (F) of this paragraph does not apply.  The owner or operator has the option of selecting which unit operations are to be controlled and to what levels, provided that the overall control meets the specified level of 90%.  Single units that qualify for exemption under §115.167(2)(B) of this title do not have to be controlled even if all units should qualify for this exemption.

               (C)  If, for the process vent streams in aggregate, the actual average flow rate value (in scfm) is greater than the value of FR calculated using the applicable RACT equation in paragraph (1) of this section (and the calculated value of FR is a positive number), then the control requirements must be evaluated with the successive ranking scheme of subparagraph (F) of this paragraph until control of a segment of unit operations is required or until all unit operations have been 
eliminated from the process pool.  Single units that qualify for exemption under §115.167(2)(B) of this
title do not have to be included in the rankings and do not have to be controlled.

               (D)  Sources that are required to be controlled to the level specified by RACT (i.e., 90%) will have an average flow rate that is below the flow rate specified by the applicable RACT equation in paragraph (1) of this section (when the source's annual emission total is input).  The applicability criterion is implemented on a two-tier basis.  First, single pieces of batch equipment corresponding to distinct unit operations shall be evaluated over the course of an entire year, regardless of what materials are handled or what products are manufactured in them.  Second, equipment shall be evaluated as an aggregate if it can be linked together based on the definition of a process.

               (E)  To determine applicability of a RACT option in the aggregation scenario, all the VOC emissions from a single process shall be summed to obtain the annual mass emission total, and the weighted average flow rate from each process vent in the aggregation shall be used as the average flow rate.

               (F)  All unit operations in the batch process, as defined for the purpose of determining RACT applicability, shall be ranked in ascending order according to their ratio of annual emissions (pounds per year) divided by average flow rate (in scfm).  Sources with the smallest ratios shall be listed first.  This list of sources constitutes the "pool" of sources within a batch process.  The annual emission total and average flow rate of the pool of sources shall then be compared against the RACT equations in paragraph (1) of this section to determine whether control of the pool is required.

                    (i)  If control is not required after the initial ranking, unit operations having the lowest annual emissions/average flow rate ratio shall then be eliminated one by one, and the characteristics of annual emission and average flow rate for the remaining pool of equipment must be evaluated with each successive elimination of a source from the pool.

                    (ii)  Control of the unit operations remaining in the pool to the specified level (i.e., 90%) shall be required once the aggregated characteristics of annual emissions and average flow rate have met the specified cutoffs.  The owner or operator has the option of selecting which unit operations are to be controlled and to what levels, provided that the overall control meets the specified level of 90%.

          (3)  Once-in, always-in.  Any batch process operation that becomes subject to the provisions of this division by exceeding provisions of §115.167 of this title will remain subject to the provision of this division, even if throughput or emissions later fall below exemption limits, unless and until emissions are reduced to no more than the controlled emissions level existing before implementation of the project by which throughput or emission rate was reduced to less than the applicable exemption limits in §115.167 of this title; and

               (A)  the project by which throughput or emission rate was reduced is authorized by any permit or permit amendment or standard permit or exemption from permitting required by Chapter 116 or Chapter 106 of this title (relating to Control of Air Pollution by Permits for New Construction or Modification; and Exemptions from Permitting).  If an exemption from permitting is available for the project, compliance with this division must be maintained for 30 days after the filing of documentation of compliance with that exemption from permitting; or

               (B)  if authorization by permit, permit amendment, standard permit, or exemption from permitting is not required for the project, the owner/operator has given the executive director 30 days’ notice of the project in writing.

§115.163.  Alternate Control Requirements.
As adopted by TNRCC October 27, 1999, effective November 18, 1999

     Alternate methods of demonstrating and documenting continuous compliance with the applicable control requirements or exemption criteria in this division (relating to Batch Processes) may be approved by the executive director in accordance with §115.910 of this title (relating to Availability of Alternate Means of Control) if emission reductions are demonstrated to be substantially equivalent.

§115.164.  Determination of Emissions and Flow Rates.
As adopted by TNRCC October 27, 1999, effective November 18, 1999

     The owner or operator of each batch process operation in the Beaumont/Port Arthur area shall determine the mass emissions and flow rates as follows.

          (1)  Determination of Uncontrolled Annual Emission Total.  The owner or operator shall determine the annual mass emissions total by using engineering estimates of the uncontrolled emissions from a process vent or group of process vents within a batch process train and multiplying by the potential or permitted number of batch cycles per year.  Engineering estimates must follow the guidance contained in EPA's Control of Volatile Organic Compound Emissions from Batch Processes - Alternative Control Techniques Information Document (EPA-453/R-94-020, February 1994).  Alternatively, if an emissions measurement is used to measure vent emissions, the measurement must conform with the requirements of measuring incoming mass flow rate of volatile organic compounds as specified in §115.165 of this title (relating to Approved Test Methods and Testing Requirements).

          (2)  Determination of Average Flow Rate.  To obtain a value for average flow rate, the owner or operator may choose to measure the flow rates or to estimate the flow rates using the estimation methods contained in EPA's Control of Volatile Organic Compound Emissions from Batch Processes - Alternative Control Techniques Information Document (EPA-453/R-94-020, February 1994).  For existing manifolds, the average flow rate may be the flow rate that was assumed in the design.

                    (i)  The sampling time for each run shall be the entire length of the batch cycle, during which readings shall be taken:

                         (I)  continuously if Method 25A is used; or

                         (II)  as often as is possible using Method 18, with a maximum of one-minute intervals between measurements throughout the batch cycle.

                    (ii)  The emission rate of the process vent or inlet to the control device shall be determined by combining continuous concentration and flow rate measurements at simultaneous points throughout the batch cycle.

                    (iii)  The mass flow rate of the control device outlet shall be determined by combining continuous concentration and flow rate measurements at simultaneous points throughout the batch cycle.

                    (iv)  The efficiency of the control device shall be determined by integrating the mass flow rates obtained in clauses (ii) and (iii) of this subparagraph over the time of the batch cycle, and dividing the difference in inlet and outlet mass flow totals by the inlet mass flow total.

               (C)  Performance requirements for flares and vapor combustors.

                    (i)  For flares, the performance test requirements of 40 CFR 60.18(b) shall apply.

                    (ii)  For vapor combustors, the owner or operator may consider the unit to be a flare and meet the performance test requirements of 40 CFR 60.18(b).

                    (iii)  Compliance with the requirements of 40 CFR 60.18(b) will be considered to represent 98% control of the VOC in the flare inlet.

               (D)  Minor modifications.  Minor modifications to these test methods may be used, if approved by the executive director.

               (E)  Alternate test methods.  Test methods other than those specified in subparagraphs (B) and (C) of this paragraph may be used if validated by 40 CFR 63, Appendix A, Test Method 301 (effective December 29, 1992).  For the purposes of this paragraph, substitute “executive director” each place that Test Method 301 references “administrator.”
