NR 440.53 Note Note: Under 40 CFR 60.393 (c) (1) (i) (C), if the owner or operator can justify to the administrator’s satisfaction that other values for transfer efficiencies are appropriate, the administrator will approve their use on a case-by-case basis.

j) When more than one application method (l) is used on an individual surface coating operation, the owner or operator shall perform an analysis to determine an average transfer efficiency by the following equation where “n” is the total number of coatings used and “p” is the total number of application methods:

4) Calculate the volume weighted average mass of VOC per volume of applied coating solids (G) during each calendar month for each affected facility by the following equation:

NR 440.53(4)(c)1.b. b. If the volume weighted average mass of VOC per volume of applied coating solids (G), calculated on a calendar month basis, is less than or equal to the applicable emission limit specified in sub. (3), the affected facility is in compliance. Each monthly calculation is a performance test for the purpose of this section.

NR 440.53(4)(c)2. 2. The owner or operator shall use the following procedures for each affected facility which uses a capture system and a control device that destroys VOC (e.g., incinerator) to comply with the applicable emission limit specified under sub. (3).

NR 440.53(4)(c)2.a. a. Calculate the volume weighted average mass of VOC per volume of applied coating solids (G) during each calendar month for each affected facility as described under subd. 1. a.

NR 440.53(4)(c)2.b. b. Calculate the volume weighted average mass of VOC per volume of applied solids emitted after the control device, by the following equation:

1) Determine the fraction of total VOC which is emitted by an affected facility that enters the control device by using the following equation where “n” is the total number of stacks entering the control device and “p” is the total number of stacks not connected to the control device:

If the owner can justify to the department’s satisfaction that another method will give comparable results, the department shall approve its use on a case-by-case basis.

a) In subsequent months, the owner or operator shall use the most recently determined capture fraction for the performance test.

2) Determine the destruction efficiency of the control device using values of the volumetric flow rate of the gas streams and the VOC content (as carbon) of each of the gas streams in and out of the device by the following equation where “n” is the total number of stacks entering the control device and “m” is the total number of stacks leaving the control device:

a) In subsequent months, the owner or operator shall use the most recently determined VOC destruction efficiency for the performance test.

3) If an emission control device controls the emissions from more than one affected facility, the owner or operator shall measure the VOC concentration

in the effluent gas entering the control device (in parts per million by volume) and the volumetric flow rate

of the effluent gas (in dry standard cubic meters per hour) entering the device through each stack. The destruction or removal efficiency determined using these data shall be applied to each affected facility served by the control device.

NR 440.53(4)(c)2.c. c. If the volume weighted average mass of VOC per volume of applied solids emitted after the control device (N) calculated on a calendar month basis is less than or equal to the applicable emission limit specified in sub. (3), the affected facility is in compliance. Each monthly calculation is a performance test for the purposes of this section.

NR 440.53(4)(c)3. 3. The owner or operator shall use the following procedures for each affected facility which uses a capture system and a control device that recovers the VOC (e.g., carbon adsorber) to comply with the applicable emission limit specified under sub. (3).

NR 440.53(4)(c)3.a. a. Calculate the mass of VOC

used during each calendar month for each affected facility as described under subd. 1. a.

NR 440.53(4)(c)3.b. b. Calculate the total volume of coating solids

used in each calendar month for each affected facility as described under subd. 1. a.

NR 440.53(4)(c)3.c. c. Calculate the mass of VOC recovered

each calendar month for each affected facility by the following equation:

NR 440.53(4)(c)3.d. d. Calculate the volume weighted average mass of VOC per volume of applied coating solids emitted after the control device during a calendar month by the following equation:

NR 440.53(4)(c)3.e. e. If the volume weighted average mass of VOC per volume of applied solids emitted after the control device (N) calculated on a calendar month basis is less than or equal to the applicable emission limit specified in sub. (3), the affected facility is in compliance. Each monthly calculation is a performance test for the purposes of this section.

NR 440.53(5) (5) Monitoring of emissions and operations. The owner or operator of an affected facility which uses an incinerator to comply with the emission limits specified under sub. (3) shall install, calibrate, maintain and operate temperature measurement devices as prescribed below:

NR 440.53(5)(a) (a) Where thermal incineration is used, a temperature measurement device shall be installed in the firebox. Where catalytic incineration is used, a temperature measurement device shall be installed in the gas stream immediately before and after the catalyst bed.

NR 440.53(5)(b) (b) Each temperature measurement device shall be installed, calibrated and maintained according to accepted practice and the manufacturer’s specifications. The device shall have an accuracy of the greater of ± 0.75% of the temperature being measured expressed in degrees Celsius or ±2.5°C.

NR 440.53(5)(c) (c) Each temperature measurement device shall be equipped with a recording device so that a permanent record is produced.

NR 440.53(6) (6) Reporting and recordkeeping requirements.

NR 440.53(6)(a) (a) Each owner or operator of an affected facility shall include the data outlined in subds. 1. and 2. in the initial compliance report required by s. NR 440.08.

NR 440.53(6)(a)1. 1. The owner or operator shall report the volume weighted average mass of VOC per volume of applied coating solids for each affected facility.

Where compliance is achieved through the use of incineration, the owner or operator shall include the following additional data in the control device initial performance test required by s. NR 440.08 (1) or subsequent performance tests at which destruction efficiency is determined: the combustion temperature (or the gas temperature upstream and downstream of the catalyst bed), the total mass of VOC per volume of applied coating solids before and after the incinerator, capture efficiency, the destruction efficiency of the incinerator used to attain compliance with the applicable emission limit specified in sub. (3), and a description of the method used to establish the fraction of VOC captured and sent to the control device.
