Section NR 465.43 - Emission limits(1) WHAT EMISSION LIMITS MUST I MEET? (a) For a new or reconstructed affected source, you shall limit organic HAP emissions to the atmosphere from the affected source to the applicable limit specified in subds. 1. to 5., except as specified in par. (c), determined according to the requirements in s. NR 465.46(2), 465.47(2) or 465.48(2). 1. For each new or reconstructed general use coating affected source, limit organic HAP emissions to no more than 0.23 kilograms (kg) (1.9 pounds (lb)) of organic HAP per liter (gallon) of coating solids used during each 12-month compliance period.2. For each new or reconstructed high performance coating affected source, limit organic HAP emissions to no more than 3.3 kg (27.5 lb) of organic HAP per liter (gallon) of coating solids used during each 12-month compliance period.3. For each new or reconstructed magnet wire coating affected source, limit organic HAP emissions to no more than 0.050 kg (0.44 lb) of organic HAP per liter (gallon) of coating solids used during each 12-month compliance period.4. For each new or reconstructed rubber-to-metal coating affected source, limit organic HAP emissions to no more than 0.81 kg (6.8 lb) of organic HAP per liter (gallon) of coating solids used during each 12-month compliance period.5. For each new or reconstructed extreme performance fluoropolymer coating affected source, limit organic HAP emissions to no more than 1.5 kg (12.4 lb) of organic HAP per liter (gallon) of coating solids used during each 12-month compliance period.(b) For an existing affected source, you shall limit organic HAP emissions to the atmosphere from the affected source to the applicable limit specified in subds. 1. to 5., except as specified in par. (c), determined according to the requirements in s. NR 465.46(2), 465.47(2) or 465.48(2). 1. For each existing general use coating affected source, limit organic HAP emissions to no more than 0.31 kg (2.6 lb) of organic HAP per liter (gallon) of coating solids used during each 12-month compliance period.2. For each existing high performance coating affected source, limit organic HAP emissions to no more than 3.3 kg (27.5 lb) of organic HAP per liter (gallon) of coating solids used during each 12-month compliance period.3. For each existing magnet wire coating affected source, limit organic HAP emissions to no more than 0.12 kg (1.0 lb) of organic HAP per liter (gallon) of coating solids used during each 12-month compliance period.4. For each existing rubber-to-metal coating affected source, limit organic HAP emissions to no more than 4.5 kg (37.7 lb) of organic HAP per liter (gallon) of coating solids used during each 12-month compliance period.5. For each existing extreme performance fluoropolymer coating affected source, limit organic HAP emissions to no more than 1.5 kg (12.4 lb) of organic HAP per liter (gallon) of coating solids used during each 12-month compliance period.(c) If your facility's surface coating operations meet the applicability criteria of more than one of the sub-category emission limits specified in par. (a) or (b), you may comply separately with each sub-category emission limit or comply using one of the alternatives in subd. 1. or 2. 1. If the general use or magnet wire surface coating operations subject to only one of the emission limits specified in par. (a) 1. or 3. or (b) 1. or 3. account for 90% or more of the surface coating activity at your facility, then compliance with that one emission limit in this subchapter for all surface coating operations constitutes compliance with the other applicable emission limits. You shall use liters (gallons) of solids used as a measure of relative surface coating activity over a representative period of operation. You may estimate the relative volume of coating solids used from parameters other than coating consumption and volume solids content. The determination of predominant activity shall accurately reflect current and projected coating operations and shall be verifiable through appropriate documentation. The use of parameters other than coating consumption and volume solids content shall be approved by the administrator. You may use data for any reasonable time period of at least one year in determining the relative amount of coating activity, as long as they represent the way the source will continue to operate in the future and are approved by the administrator. You shall determine the predominant activity at your facility and submit the results of that determination with the initial notification required by s. NR 465.45(1) (b). Additionally, you shall determine the facility's predominant activity annually and include the determination in the next semi-annual compliance report required by s. NR 465.45(2) (a). Note: An example of parameters other than coating consumption and mass solids content for estimating the relative mass of coating solids used would be design specifications for the parts or products coated and the number of items produced.
2. You may calculate and comply with a facility-specific emission limit as described in subd. 2. a. to c. If you elect to comply using the facility-specific emission limit alternative, then compliance with the facility-specific emission limit and the emission limits specified in pars. (a) and (b) for all surface coating operations constitutes compliance with this and other applicable surface coating NESHAP. In calculating a facility-specific emission limit, you shall include coating activities that meet the applicability criteria of the other sub-categories and constitute more than one percent of total coating activities. Coating activities that meet the applicability criteria of other surface coating NESHAP but comprise less than one percent of coating activities need not be included in the determination of predominant activity but shall be included in the compliance calculation.a. You are required to calculate the facility-specific emission limit for your facility when you submit the notification of compliance status required in s. NR 465.45(1) (c), and on a monthly basis afterward using the coating data for the relevant 12-month compliance period.b. Use Equation 1 of this subsection to calculate the facility-specific emission limit for your surface coating operations for each 12-month compliance period: See Image
where:
Facility-specific emission limit is the facility-specific emission limit for each 12-month compliance period, kg (lb) of organic HAP per kg (lb) of coating solids used
Limiti is the new source or existing source emission limit as specified in s. NR 465.43(1) applicable to coating operation, i, included in the facility-specific emission limit, converted to kg (lb) of organic HAP per kg (lb) of coating solids used, if the emission limit is not already in those units. All emission limits included in the facility-specific emission limit shall be in the same units.
Solidsi is the liters (gallons) of solids used in coating operation, i, in the 12-month compliance period that is subject to emission limit, i, as specified in s. NR 465.43(1). You may estimate the volume of coating solids used from parameters other than coating consumption and volume solids content, such as design specifications for the parts or products coated and the number of items produced. The use of parameters other than coating consumption and volume solids content shall be approved by the administrator.
n is the number of different coating operations included in the facility-specific emission limit
c. If you need to convert an emission limit in another surface coating NESHAP from kg (lb) of organic HAP per kg (lb) of coating solids used to kg (lb) of organic HAP per liter (gallon) of coating solids used, you shall use the default solids density of 1.26 kg of solids per liter of coating solids (10.5 lb of solids per gallon of coating solids).(2) WHAT ARE MY OPTIONS FOR MEETING THE EMISSION LIMITS? You shall include all coatings, thinners and other additives, and cleaning materials used in the affected source when determining whether the organic HAP emission rate is equal to or less than the applicable emission limit in sub. (1). To make this determination, you shall use at least one of the 3 compliance options listed in pars. (a) to (c). You may apply any of the compliance options to an individual coating operation, or to multiple coating operations as a group, or to the entire affected source. You may use different compliance options for different coating operations, or at different times on the same coating operation. You may employ different compliance options when different coatings are applied to the same part, or when the same coating is applied to different parts. However, you may not use different compliance options at the same time on the same coating operation. If you switch between compliance options for any coating operation or group of coating operations, you shall document this switch as required by s. NR 465.45(3) (c), and you shall report it in the next semiannual compliance report required in s. NR 465.45(2). (a)Compliant material option. You shall meet all the requirements of s. NR 465.46 to demonstrate compliance with the applicable emission limit in sub. (1) using this option. To use this option, you shall demonstrate that the organic HAP content of each coating used in the coating operation or operations is less than or equal to the applicable emission limit in sub. (1), and that each thinner and other additive, and cleaning material used contains no organic HAP. (b)Emission rate without add-on controls option. You shall meet all the requirements of s. NR 465.47 to demonstrate compliance with the emission limit in sub. (1) using this option. To use this option, you shall demonstrate that, based on the coatings, thinners and other additives, and cleaning materials used in the coating operation or operations, the organic HAP emission rate for the coating operation or operations is less than or equal to the applicable emission limit in sub. (1), calculated as a rolling 12-month emission rate and determined on a monthly basis. (c)Emission rate with add-on controls option. You shall meet all the requirements of s. NR 465.48 to demonstrate compliance with the emission limits in sub. (1), the operating limits in sub. (3) and the work practice standards in sub. (4) using this option. To use this option, you shall demonstrate that, based on the coatings, thinners and other additives, and cleaning materials used in the coating operation or operations, and the emissions reductions achieved by emission capture systems and add-on controls, the organic HAP emission rate for the coating operation or operations is less than or equal to the applicable emission limit in sub. (1), calculated as a rolling 12-month emission rate and determined on a monthly basis. If you use this compliance option, you shall also demonstrate that all emission capture systems and add-on control devices for the coating operation or operations meet the operating limits required in sub. (3), except for solvent recovery systems for which you conduct liquid-liquid material balances according to s. NR 465.48(2) (j), and that you meet the work practice standards required in sub. (4). (3) WHAT OPERATING LIMITS MUST I MEET? (a) For any coating operation or operations on which you use the compliant material option specified in sub. (2) (a) or the emission rate without add-on controls option specified in sub. (2) (b), you are not required to meet any operating limits.(b) For any controlled coating operation or operations on which you use the emission rate with add-on controls option specified in sub. (2) (c), except those for which you use a solvent recovery system and conduct a liquid-liquid material balance according to s. NR 465.48(2) (j), you shall meet the operating limits specified in Table 1 of this subchapter. These operating limits apply to the emission capture and control systems on the coating operations for which you use this option, and you shall establish the operating limits during the performance test according to the requirements in s. NR 465.48(8). You shall meet the operating limits at all times after you establish them.(c) If you use an add-on control device other than those listed in Table 1 of this subchapter, or wish to monitor an alternative parameter and comply with a different operating limit, you shall apply to the administrator for approval of alternative monitoring under 40 CFR 63.8(f).(4) WHAT WORK PRACTICE STANDARDS SHALL I MEET? (a) For any coating operation or operations on which you use the compliant material option specified in sub. (2) (a) or the emission rate without add-on controls option specified in sub. (2) (b), you are not required to meet any work practice standards.(b) If you use the emission rate with add-on controls option in sub. (2) (c), you shall develop and implement a work practice plan to minimize organic HAP emissions from the storage, mixing and conveying of coatings, thinners, other additives and cleaning materials used in, and waste materials generated by the controlled coating operations for which you use this option; or you shall meet an alternative standard as provided in par. (c). The plan shall specify practices and procedures to ensure that, at a minimum, the elements specified in subds. 1. to 5. are implemented. 1. All organic-HAP-containing coatings, thinners, other additives, cleaning materials and waste materials shall be stored in closed containers.2. Spills of organic-HAP-containing coatings, thinners, other additives, cleaning materials and waste materials shall be minimized.3. Organic-HAP-containing coatings, thinners, other additives, cleaning materials and waste materials shall be conveyed from one location to another in closed containers or pipes.4. Mixing vessels which contain organic-HAP-containing coatings and other materials shall be closed except when adding to, removing or mixing the contents.5. Emissions of organic HAP shall be minimized during cleaning of storage, mixing and conveying equipment.(c) As provided in 40 CFR 63.6(g), the U. S. EPA may choose to grant you permission to use an alternative to the work practice standards in this subsection.Wis. Admin. Code Department of Natural Resources NR 465.43
