(1) Determination of Volatile Organic Content of Surface Coatings.

(a) This method applies to paint, varnish, lacquer, and surface coatings which are air-dried or force-dried.

(b) This method does not apply to any coating system requiring a special curing process such as:

exposure to temperatures in excess of 110° C (230° F) to promote thermal cross-1inking; or
exposure to ultraviolet light to promote cross-1inking.

Class I: General Solvent-Type Paints. This class includes white linseed oil outside paint, white soya and phthalic alkyd enamel, white linseed o-phthalic alkyd enamel, red lead primer, zinc chromate primer, flat white inside enamel, white epoxy enamel, white vinyl toluene modified alkyd, white amino modified baking enamel, and other solvent-type paints not included in Class II.

Class III: Water Thinned Paints. This class includes emulsion or latex paints and colored enamels.

(d) For the purposes of this method, a representative sample of the surface coating shall be obtained at the point of delivery to the coater or any other point in the process that the Director approves.

(e) The volatile organic content of the sample shall be determined as follows:

Assign the coating to one of the three classes in subparagraph (c) of this paragraph. Assign any coating not clearly belonging to Class II or III to Class I.
Determine the density Dm (in grams/cubic centimeter) of the paint, varnish, lacquer, or related product according to the procedure outlined in ASTM 1475-60, Standard Method of Test for density of Paint, Varnish, Lacquer, and Related Products. Then, depending on the class of the coatings, use one of the following specified procedures to determine the volatile content:

(IV) To convert grams/liter to pounds/gallon, multiply Cv by 8.3455 x 10^-3.

(2) Test Procedure for Determination of VOC Emissions from Bulk Gasoline Terminals.

(a) Principle. VOC mass emissions are determined directly using flow meters and hydrocarbon analyzers. The volume of liquid gasoline dispensed is determined by computation based on the metered quantity of gasoline at the loading rack. Test results are expressed in milligrams of hydrocarbons emitted per liter of gasoline transferred.

(b) Summary of the Method. This method describes the test conditions and test procedures to be followed in determining the emissions from systems installed to control VOC vapors resulting from tank truck and trailer loading operations at bulk terminals. Under this procedure direct measurements are made to compute the hydrocarbon mass exhausted from the vapor control system. All possible sources of leaks are qualitatively checked to ensure that no uncontrolled vapors are emitted to the atmosphere. The results are expressed in terms of mass hydrocarbons emitted per unit volume of gasoline transferred. Emissions are determined on a total hydrocarbon basis. If methane is present in the vapors returned from the tank trucks or trailers, provisions are included for conversion to a total nonmethane hydrocarbon basis.

(c) Applicability. This method is applicable to determining VOC emission rates at tank truck and trailer gasoline loading terminals employing vapor collection systems and either continuous or intermittent vapor control systems. This method is applicable to motor tank truck and trailer loading only as per Rule 335-3-6-.06.

(d) Apparatus. The components essential to the evaluation of emissions from gasoline loading terminals are:

portable combustible gas detector equipped to read zero (0) to one hundred percent (100%) of the lower explosive limit,
flexible thermocouple with recorder,
gas volume meter, sized for the expected exhaust flow rate and range,
total hydrocarbon analyzer with recorder (flame ionization detector or nondispersive infrared equipped to read zero (0) to ten percent (10%) by volume hydrocarbon as propane for vapor control systems which recover the vapor liquid, or 0 to 10,000 ppmv hydrocarbon as propane for incineration vapor control system),
barometer to measure atmospheric pressure,
gas chromatography/flame ionization detector with a column to separate C1 - C7 alkanes (used if methane is present in recovered vapors or if incineration is the vapor control technique).

(e) Test Requirements:

No less than three 8-hour repetitions will be performed.
During the test period, all loading racks shall be open for each produce line which is controlled by the system under test. Simultaneous use of more than one loading rack shall occur to the extent that such would normally occur.
Simultaneous use of more than one dispenser on each loading rack shall occur to the extent that such use would normally occur.
Dispensing rates shall be set at the maximum rate at which the equipment is designed to be operated. Automatic product dispensers are to be used according to normal operating practices.
Applicable operating parameters of the vapor control system shall be monitored to demonstrate that the control unit is operating at design levels. For intermittent vapor control systems employing a vapor holder, each test repetition shall include at least one fully automatic operation cycle of the vapor holder and control device. Tank trucks and trailers shall be essentially leak free as determined by the Director.

(f) Basic Measurements Required. The basic measurements essential to the evaluation of emissions from gasoline loading terminals are:

the amount of gasoline dispensed from gasoline dispensers,
leak check of all fittings and vents,
the following items for the processing unit exhaust:

(i) temperature,

(ii) pressure,

(iii) volume of vapors,

(iv) hydrocarbon concentration of vapors, if methane is present, in recovered vapors.

(g) Test Procedure.

Calibrate and span all instruments as outlined under subparagraph (i) of this paragraph.
Install an appropriately sized gas meter on the exhaust vent of the vapor control system. For those vapor control systems where restrictions preclude the use of a volume meter or when incineration is used for vapor control, a gas flow rate meter (orifice, pitot tube, annubar, etc.) is necessary. At the meter inlet, install a thermocouple with recorder. Install a tap at the volume meter outlet. Attach a sample line for total hydrocarbon analyzer (0 to 10 percent) as propane to this tap. If the meter pressure is different than barometric pressure, install a second tap at the meter outlet and attach an appropriate manometer for pressure measurement. If methane analysis is required, install a third tap for connection to a constant volume sample pump/evacuated bag assembly as described in 40 CFR 36.247, Method 3, December 23, 1977.
Measurements and data required for evaluating emissions from the system:

(i) at the beginning and end of each test repetition, record the volume readings on each product dispenser on each loading rack served by the system under test;

(ii) at the beginning of each test repetition and each two (2) hours thereafter, record the ambient temperature and the barometric pressure;

(iii) for intermittent vapor control systems employing a vapor holder, the unit shall be manually started and allowed to process vapors in the holder until the lower automatic cut-off is reached. This cycle should be performed immediately prior to the beginning of the test repetition before readings under Subparagraph (g)3.(i) of this paragraph are taken. No loading shall be in progress during this manual cycle;

(iv) for each cycle of the vapor control system during each test repetition, record the start and stop time, the initial and final gas meter readings, and the average vapor temperature, pressure and hydrocarbon concentration. If a flow rate meter is used, record flow meter readouts continuously during the cycle. If required, extract a sample continuously during each cycle for chromatographic analysis for specific hydrocarbons;

(v) for each tank truck or trailer loading during the test period, check all fittings and seals on the tanker compartments with the combustible gas detector. Record the maximum combustible gas reading for any incidents of leakage of hydrocarbon vapors. Explore the entire periphery of the potential leak source with the sample hose inlet 1 cm (0.4 inches) away from the interface;

(vi) during each test period, monitor all possible sources of leaks in the vapor collection and control systems with the combustible gas indicator. Record the location and combustible gas reading for any incidents of leakage;

(vii) for intermittent vapor control systems, the control unit shall be manually started and allowed to process vapors in the holder until the lower automatic shutoff is reached at the end of each test repetition. Record the data required under subparagraph (g)3.(iv) of this paragraph for this manual cycle. No loading shall be in progress during this manual cycle.

Record the weight and type of work load degreased each day.
At the end of the test run, pump out the used solvent and measure the amount with a flow meter. Also, estimate the volume of metal chips and other material remaining in the emptied sump, if significant.
Bottle a sample of the used solvent and analyze it to find the percent that is oil and other contaminants. The oil and solvent proportions can be estimated by weighing samples of used solvent before and after boiling off the solvent. Compute the volume of oils in the used solvent. The volume of solvent displaced by this oil along with the volume of make-up solvent added during operations are equal to the solvent emission.

(13) Capture Efficiency Test Procedures for Volatile Organic Compound Emissions Capture and Control Systems.

(a) For the purposes of this Rule, the following definitions and abbreviations apply:

"Capture" means the containment or recovery of emissions from a process for direction into a duct which may be exhausted through a stack or sent to a control device.
"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.
"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.
"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.
"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.
"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.
"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.
"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.
"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.
"Overall Emission Reduction Efficiency," means the weight per unit time of VOC removed by a control device divided by the weight per unit time of VOC emitted by an emission source, expressed as a percentage. The overall emission reduction efficiency is the product of the capture efficiency and the control equipment destruction or removal efficiency.
"Method 204D" is the EPA-approved test procedure to determine the fugitive volatile organic compound (VOC) emissions from temporary total enclosures (TTE). It is intended to be used as a segment in the development of liquid/gas or gas/gas protocols for determining VOC capture efficiency (CE) for surface coating and printing operations. Refer to Appendix F for Method 204D.
"Method 204E" is the EPA-approved test procedure to determine the fugitive volatile organic compound (VOC) emissions from a building enclosure (BE). It is intended to be used as a segment in the development of liquid/gas or gas/gas protocols for determining VOC capture efficiency (CE) for surface coating and printing operations. Refer to Appendix F for Method 204E.
"Method 204B" is the EPA-approved test procedure to determine the volatile organic compounds (VOC) content of captured gas streams. It is intended to be used as a segment in the development of liquid/gas or gas/gas protocols for determining VOC capture efficiency (CE) for surface coating and printing operations. 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.
"Method 204C" is the EPA-approved test Method 204o determine the volatile organic compounds (VOC) content of captured gas streams. It is intended to be used as a segment in the development of gas/gas protocol in which fugitive VOC emissions are measured for determining VOC capture efficiency (CE) for surface coating and printing operations. A dilution system is used to reduce the VOC concentration of the captured emissions to about the same concentration as the fugitive emissions. 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 204C.
"Method 204A and 204F" are the EPA-approved test procedure to determine the input of volatile organic compounds (VOC) to a VOC emitting process. They are intended to be used as a segment in the development of liquid/gas protocols for determining VOC capture efficiency (CE) for surface coating and printing operations. Refer to Appendix F for Methods 204A and 204F.
"Method 204" is the EPA-approved procedure to determine whether a permanent or temporary enclosure meets the criteria of a total enclosure. Refer to Appendix F for Method 204.
"F" shall be an abbreviation for the mass of VOC leaving the process as gaseous fugitive emissions.
"G" shall be an abbreviation for the mass of VOC captured and delivered to a control device.
"L" shall be an abbreviation for the mass of VOC input to the process in liquid form.
"PTE" shall be an abbreviation for a permanent total enclosure, which contains a process that emits VOC and meets the specifications in Method 204.
"TTE" shall be an abbreviation for a temporary total enclosure which is built around a process that emits VOC and meets the specifications given in Method 204.
"BE" shall be an abbreviation for a building or room enclosure that contains a process that emits VOC. If a BE is to serve as a PTE or TTE, the appropriate requirements given in Method 204 shall be met.

(b) Applicability.

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.
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.
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.

The capture efficiency of a process line shall be measured using one of the four protocols given in subparagraph (c)3. of this paragraph.
Any error margin associated with a test protocol may not be incorporated into the results of a capture efficiency test.
The four specific capture efficiency protocols are discussed in subparagraphs (c)3.(i) through (c)3.(iv) of this paragraph below. Any affected source shall use one of these protocols to measure capture efficiency, unless a suitable alternative protocol is approved by EPA as a SIP revision.

(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)L

where:

CE = capture efficiency, decimal fraction.

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

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)L

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.

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.
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.
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.

(4) An affected source utilizing a PTE shall demonstrate that this enclosure meets the requirement given in Method 204 for a PTE during any testing of a control system.

(5) An affected source utilizing a TTE shall demonstrate that its TTE meets the requirements given in Method 204 for a TTE during the test of their control system. The source shall also provide documentation that the quality assurance criteria for a TTE have been achieved.
