NR 466.24(2)(e)9.c.c. For a catalytic oxidizer, install, calibrate, operate and maintain a temperature monitoring device equipped with a continuous recorder. The device shall be capable of monitoring temperature with an accuracy of ±1% of the temperature being monitored in degrees Celsius or ±1° Celsius, whichever is greater. The thermocouple or temperature sensor shall be installed in the vent stream at the nearest feasible point to the inlet and outlet of the catalyst bed. Calculate the temperature rise across the catalyst.

NR 466.24(2)(e)10.10. If you use a control device other than an oxidizer or wish to monitor an alternative parameter and comply with a different operating limit, you shall apply to the department for approval of an alternative monitoring method under s. NR 460.07 (6).

NR 466.24(2)(f)(f) Capture system monitoring. If you are complying with the emission standards in s. NR 466.23 (1) through the use of a capture system and control device for one or more web coating lines, you shall develop a site-specific monitoring plan containing the information specified in subds. 1. and 2. for the capture systems. You shall monitor the capture system in accordance with subd. 3. You shall make the monitoring plan available for inspection by the department upon request.

NR 466.24(2)(f)2.2. The monitoring plan shall specify the operating parameter value or range of values that demonstrate compliance with the emission standards in s. NR 466.23 (1). The specified operating parameter value or range of values shall represent the conditions present when the capture system is being properly operated and maintained.

NR 466.24(2)(f)4.4. Any deviation from the operating parameter value or range of values which are monitored according to the plan will be considered a deviation from the operating limit.

NR 466.24(3)(a)(a) Performance test methods. The performance test methods you shall use are as follows:

NR 466.24(3)(b)(b) Exceptions. If you are using a control device to comply with the emission standards in s. NR 466.23 (1), you are not required to conduct a performance test to demonstrate compliance if one or more of the criteria in subds. 1. to 3. are met.

NR 466.24(3)(b)1.1. The control device is equipped with continuous emission monitors for determining inlet and outlet total organic volatile matter concentration and capture efficiency has been determined in accordance with the requirements of this subchapter such that an overall organic HAP control efficiency can be calculated, and the continuous emission monitors are used to demonstrate continuous compliance in accordance with sub. (2).

NR 466.24(3)(c)(c) Organic HAP content. If you determine compliance with the emission standards in s. NR 466.23 (1) by means other than determining the overall organic HAP control efficiency of a control device, you shall determine the organic HAP mass fraction of each coating material as-purchased by following one of the procedures in subds. 1. to 3., and determine the organic HAP mass fraction of each coating material as-applied by following the procedures in subd. 4. If the organic HAP content values are not determined using the procedures in subds. 1. to 3., you shall submit an alternative test method for determining their values for approval by the administrator in accordance with 40 CFR 63.7 (f). The recovery efficiency of the test method shall be determined for all of the target organic HAP and a correction factor, if necessary, shall be determined and applied.

NR 466.24(3)(c)1.1. ‘Method 311.’ You may test the coating material in accordance with Method 311 of 40 CFR part 63, Appendix A, incorporated by reference in s. NR 484.04 (25). The Method 311 determination may be performed by the manufacturer of the coating material and the results provided to the owner or operator. The organic HAP content shall be calculated according to the criteria and procedures in subd. 1. a. to c.

NR 466.24(3)(c)1.a.a. Include each organic HAP determined to be present at greater than or equal to 0.1% by mass for the United States occupational safety and health administration-defined (OSHA-defined) carcinogens as specified in 29 CFR 1910.1200 (d) (4) and greater than or equal to 1.0% by mass for other organic HAP compounds.

NR 466.24(3)(c)1.b.b. Express the mass fraction of each organic HAP you include according to subd. 1. a. as a value truncated to 4 places after the decimal point, e.g., 0.3791.

NR 466.24(3)(c)1.c.c. Calculate the total mass fraction of organic HAP in the tested material by summing the counted individual organic HAP mass fractions and truncating the result to 3 places after the decimal point, e.g., 0.763.

NR 466.24(3)(c)2.2. ‘Method 24.’ For coatings, determine the volatile organic content as mass fraction of non-aqueous volatile matter and use it as a substitute for organic HAP using Method 24 of 40 CFR part 60, Appendix A, incorporated by reference in s. NR 484.04 (13). The Method 24 determination may be performed by the manufacturer of the coating and the results provided to you.

NR 466.24(3)(c)3.3. ‘Formulation data.’ You may use formulation data to determine the organic HAP mass fraction of a coating material. Formulation data may be provided to you by the manufacturer of the material. In the event of an inconsistency between Method 311 of 40 CFR part 63, Appendix A, incorporated by reference in s. NR 484.04 (25), test data and a facility’s formulation data, and the Method 311 test value is higher, the Method 311 data will govern. Formulation data may be used provided that the information represents all organic HAP present at a level equal to or greater than 0.1% for OSHA-defined carcinogens as specified in 29 CFR 1910.1200 (d) (4) and equal to or greater than 1.0% for other organic HAP compounds in any raw material used.

NR 466.24(3)(c)4.4. ‘As-applied organic HAP mass fraction.’ If the as-purchased coating material is applied to the web without any solvent or other material added, the as-applied organic HAP mass fraction is equal to the as-purchased organic HAP mass fraction. Otherwise, the as-applied organic HAP mass fraction shall be calculated using Equation 1a of s. NR 466.25.

NR 466.24(3)(d)(d) Volatile organic and coating solids content. If you determine compliance with the emission standards in s. NR 466.23 (1) by means other than determining the overall organic HAP control efficiency of a control device and you choose to use the volatile organic content as a surrogate for the organic HAP content of coatings, you shall determine the as-purchased volatile organic content and coating solids content of each coating material applied by following the procedures in subd. 1. or 2. and the as-applied volatile organic content and coating solids content of each coating material by following the procedures in subd. 3.

NR 466.24(3)(d)1.1. ‘Method 24.’ You may determine the volatile organic and coating solids mass fraction of each coating applied using Method 24 in 40 CFR part 60, Appendix A, incorporated by reference in s. NR 484.04 (13). The Method 24 determination may be performed by the manufacturer of the material and the results provided to you. If these values cannot be determined using Method 24, you shall submit an alternative technique for determining their values for approval by the administrator.

NR 466.24(3)(d)2.2. ‘Formulation data.’ You may determine the volatile organic content and coating solids content of a coating material based on formulation data and may rely on volatile organic content data provided by the manufacturer of the material. In the event of any inconsistency between the formulation data and the results of Method 24 in 40 CFR part 60, Appendix A, incorporated by reference in s. NR 484.04 (13), and the Method 24 results are higher, the results of Method 24 will govern.
