NR 440.48(5)(a)(a) The owner or operator of an affected facility which uses a capture system and an incinerator to comply with the emission limits specified under sub. (3) shall install, calibrate, maintain and operate temperature measurement devices according to the following procedures:

NR 440.48(5)(a)1.1. 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 440.48(5)(a)2.2. Each temperature measurement device shall be installed, calibrated and maintained according to 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 440.48(5)(b)(b) The owner or operator of an affected facility which uses a capture system and a solvent recovery system to comply with the emission limits specified under sub. (3) shall install the equipment necessary to determine the total volume of VOC solvent recovered daily.

NR 440.48(6)(a)(a) The reporting requirements of s. NR 440.08 (1) apply only to the initial performance test. Each owner or operator subject to the provisions of this section shall include the following data in the report of the initial performance test required under s. NR 440.08 (1):

NR 440.48(6)(a)1.1. Except as provided in subd. 2., the volume-weighted average mass of VOCs emitted to the atmosphere per volume of applied coating solids (N) for a period of one calendar month from each affected facility.

NR 440.48(6)(a)2.2. For each affected facility where compliance is determined under the provisions of sub. (4) (c) 1. d., a list of the coatings used during a period of one calendar month, the VOC content of each coating calculated from data determined using Method 24 of 40 CFR part 60, Appendix A, incorporated by reference in s. NR 440.17 (1), or supplied by the manufacturer of the coating, and the minimum transfer efficiency of any coating application equipment used during the month.

NR 440.48(6)(a)3.3. For each affected facility where compliance is achieved through the use of an incineration system, the following additional information shall be reported:

NR 440.48(6)(a)4.4. For each affected facility where compliance is achieved through the use of a solvent recovery system, the following additional information shall be reported:

NR 440.48(6)(b)(b) Following the initial performance test, the owner or operator of an affected facility shall identify, record, and submit a written report to the department every calendar quarter of each instance in which the volume-weighted average of the total mass of VOC’s emitted to the atmosphere per volume of applied coating solids (N) is greater than the limit specified under sub. (3). If no such instances have occurred during a particular quarter, a report stating this shall be submitted to the department semiannually.

NR 440.48(6)(c)(c) Following the initial performance test, the owner or operator of an affected facility shall identify, record, and submit at the frequency specified in s. NR 440.07 (3) the following:

NR 440.48(6)(c)1.1. Where compliance with sub. (3) is achieved through the use of thermal incineration, each 3-hour period when metal furniture is being coated during which the average temperature of the device was more than 28°C below the average temperature of the device during the most recent performance test at which destruction efficiency was determined as specified under sub. (4).

NR 440.48(6)(c)2.2. Where compliance with sub. (3) is achieved through the use of catalytic incineration, each 3-hour period when metal furniture is being coated during which the average temperature of the device immediately before the catalyst bed is more than 28°C below the average temperature of the device immediately before the catalyst bed during the most recent performance test at which destruction efficiency was determined as specified under sub. (4). Additionally, when metal furniture is being coated, all 3-hour periods during which the average temperature difference across the catalyst bed is less than 80% of the average temperature difference across the catalyst bed during the most recent performance test at which destruction efficiency was determined as specified under sub. (4) will be recorded.

NR 440.48(6)(c)3.3. For thermal and catalytic incinerators, if no periods as described in subds. 1. and 2. occur, the owner or operator shall state this in the report.

NR 440.48(6)(d)(d) Each owner or operator subject to the provisions of this section shall maintain at the source, for a period of at least 2 years, records of all data and calculations used to determine VOC emissions from each affected facility. Where compliance is achieved through the use of thermal incineration each owner or operator shall maintain at the source daily records of the incinerator combustion chamber temperature. If catalytic incineration is used, the owner or operator shall maintain at the source daily records of the gas temperature, both upstream and downstream of the incinerator catalyst bed. Where compliance is achieved through the use of a solvent recovery system, the owner or operator shall maintain at the source daily records of the amount of solvent recovered by the system for each affected facility.

NR 440.48(7)(a)(a) The reference methods in 40 CFR part 60, Appendix A, incorporated by reference in s. NR 440.17, except as provided under s. NR 440.08 (2) shall be used to determine compliance with sub. (3) as follows:

NR 440.48(7)(a)1.1. Method 24, or coating manufacturer’s formulation data for use in the determination of VOC content of each batch of coating as applied to the surface of the metal parts but in case of an inconsistency between the Method 24 results and the formulation data, the Method 24 results will govern,
