2. "Capture System" means all equipment (including, but not limited to, hoods, ducts, fans, booths, ovens, dryers, etc.) that contains, collects, and transports an air pollutant to a control device.

3. "Capture Efficiency" means the weight per unit time of VOC entering a capture system and delivered to a control device divided by the weight per unit time of total VOC generated by a source of VOC, expressed as a percentage.

4. "Control Device" means equipment (such as an incinerator or carbon adsorber) used to reduce, by destruction or removal, the amount of air pollutant(s) in an air stream prior to discharge to the ambient air.

5. "Control System" means a combination of one or more capture system(s) and control devices working in concert to reduce discharges of pollutants to the ambient air.

6. "Destruction or Removal Efficiency" means the efficiency, expressed as a decimal fraction, of a control device in destroying or removing contaminants calculated as one minus the amount of VOC exiting the control device divided by the amount of VOC entering the control device, e.g., [1 - (10 ppm/100 ppm)] = 0.9.

7. "Gas/Gas Method" means either of two methods for determining capture which rely only on gas phase measurements. One method requires construction of a temporary total enclosure (TTE) to assure all would be fugitive emissions are measured while the other uses the room or building which houses the emission source as an enclosure.

8. "Hood" means a device used to ventilate process equipment by capturing emissions of heat or air contaminants, e.g. organic vapors or other fumes, which are then conveyed through exhaust system ductwork to a more convenient discharge point or to air pollution control equipment.

9. "Liquid/Gas Method" means either of two methods for determining capture which require both gas phase and liquid phase measurements and analysis. One liquid/gas method requires construction of a temporary total enclosure, the other uses the building or room which houses the facility as a permanent total enclosure.

The procedure may not be acceptable in certain site-specific situations, e.g., when (1) direct fired heaters or other circumstances affect the quantity of VOC at the control device inlet; and (2) particulate organic aerosols are formed in the process and are present in the captured emissions. Refer to Appendix F for Method 204B.

14. "Method 204C" is the EPA-approved test Method 204o determine the volatile organic compounds (VOC) content of captured gas streams.

(b)Applicability.

1. The requirements of subparagraph (3)(c) of this Rule shall apply to all regulated VOC emitting processes employing a control system except as provided below.

2. If a source installs a PTE that meets EPA specifications, and which directs all VOC to a control device, the capture efficiency is assumed to be 100 percent, and the source is exempted from the requirements described in subparagraph (3)(c) of this Rule. The EPA specifications to determine whether a structure is considered a PTE are given in Method 204. This does not exempt a source from performance of any control device efficiency testing required under these or any other regulations. In addition, a source shall demonstrate that all criteria for a PTE are met during the testing for control efficiency.

3. If a source uses a control device designed to collect and recover VOC (e.g. carbon adsorber), an explicit measurement of capture efficiency is not necessary if the conditions given below are met. The overall control of the system can be determined by directly comparing the input liquid (L) to the recovered liquid VOC. The general procedure for use in this situation is given in 40 CFR 60.433 with the following additional restrictions:

(i) The source shall be able to equate solvent usage with solvent recovery on a 24-hour (daily) basis, rather than a 30-day weighted average as given in 40 CFR 60.433. This shall be done within 72 hours following each 24-hour period. In addition, one of the following two criteria shall be met:

(ii) The solvent recovery system (i.e., capture and control system) shall be dedicated to a single process line (e.g., one process line venting to a carbon adsorber system), or

(iii) If the solvent recovery system controls multiple process lines, the source shall be able to demonstrate that the overall control (i.e., the total recovered solvent VOC divided by the sum of liquid VOC input to all process lines venting to the control system) meets or exceeds the most stringent standard applicable for any process line venting to the control system.

(c)Specific requirements.

1. The capture efficiency of a process line shall be measured using one of the four protocols given in subparagraph (c)3. of this paragraph.

2. Any error margin associated with a test protocol may not be incorporated into the results of a capture efficiency test.

(i)Gas/Gas Method using TTE. The EPA specifications to determine whether a temporary enclosure is considered a TTE are given in Method 204. The capture efficiency equation to be used for this Protocol is:

CE = Gw

(Gw + Fw)

where:

CE = capture efficiency, decimal fraction.

Gw = mass of VOC captured and delivered to the control device using a TTE. Method 204C is used to obtain Gw.

Fw = mass of fugitive VOC that escapes from a TTE. Method 204D is used to obtain Fw.

(ii)Liquid/Gas Method using TTE. The EPA specifications to determine whether a temporary enclosure is considered a TTE are given in Method 204. The capture efficiency equation to be used for this Protocol is:

CE = (L - F)

where:

F = mass of fugitive VOC that escapes from a TTE. Method 204D is used to obtain F.

(iii)Gas/Gas Method using the building or room (BE) in which the affected source is located as the enclosure and in which G and F are measured while operating only the affected facility. All fans and blowers in the building or room shall be operated as they would under normal production. The capture efficiency equation to be used for this Protocol is:

CE = G

(G + Fb)

where:

CE = capture efficiency, decimal fraction.

G = mass of VOC captured and delivered to a control device. Method 204C is used to obtain G.

Fb = mass of fugitive VOC that escapes from the building enclosure. Method 204E is used to obtain Fb.

(iv)Liquid/Gas Method using the building or room (BE) in which the affected source is located as the enclosure and in which L and F are measured while operating only the affected facility. All fans and blowers in the building or room shall be operated as they would under normal production. The capture efficiency equation to be used for this protocol is:

CE = (L - Fb)

where:

CE = capture efficiency, decimal fraction.

L = mass of liquid VOC input to the process. Methods 204A or 204F are used to obtain L.

Fb = mass of fugitive VOC that escapes from building enclosure. Method 204E is used to obtain Fb.

(d)Recordkeeping and Reporting.

1. The owner or operator of all affected facilities shall maintain a copy of the capture efficiency protocol submitted to the Director on file. All results of appropriate test methods and CE procedures shall be reported to the Director within thirty (30) days of the test date. These records shall be retained by the owner or operator for a minimum of three (3) years after the test date.

2. Prior to making any changes to the capture or control equipment of an affected source, the owner or operator of the source shall notify the Director in writing of these changes in accordance with the permitting requirements under Rule 335-3-14-.01.

3. The owner or operator of an affected source shall notify the Director thirty (30) days prior to performing any capture efficiency test and/or control efficiency tests.
