0.0416 is a conversion factor for molar volume, kg-moles per cubic meter (mol/m3) at 293 Kelvin (K) and 760 millimeters of mercury (mmHg)
NR 466.24(3)(e)1.i.i. For each run, emission control device destruction or removal efficiency shall be determined using Equation 2: where:
E is the organic volatile matter control efficiency of the control device, percent
Mfi is the organic volatile matter mass flow rate at the inlet to the control device, kg/h
Mfo is the organic volatile matter mass flow rate at the outlet of the control device, kg/h
NR 466.24(3)(e)1.j.j. The control device destruction or removal efficiency is determined as the average of the efficiencies determined in the test runs and calculated in Equation 2 of this section. NR 466.24(3)(e)2.2. You shall record process information as may be necessary to determine the conditions in existence at the time of the performance test. Operations during periods of startup, shutdown and malfunction will not constitute representative conditions for the purpose of a performance test. NR 466.24(3)(e)3.3. If you are using one or more add-on control devices other than a solvent recovery system for which you conduct a liquid-liquid material balance to comply with the emission standards in s. NR 466.23 (1), you shall establish the applicable operating limits required by s. NR 466.23 (2). The operating limits apply to each add-on emission control device, and you shall establish the operating limits during the performance test required by this paragraph according to the requirements in subd. 3. a. or b. NR 466.24(3)(e)3.a.a. If your add-on control device is a thermal oxidizer, establish the operating limits according to the following 2 requirements: 1) During the performance test, you shall monitor and record the combustion temperature at least once every 15 minutes during each of the 3 test runs. You shall monitor the temperature in the firebox of the thermal oxidizer or immediately downstream of the firebox before any substantial heat exchange occurs.
2) Use the data collected during the performance test to calculate and record the average combustion temperature maintained during the performance test. This average combustion temperature is the minimum operating limit for your thermal oxidizer.
NR 466.24(3)(e)3.b.b. If your add-on control device is a catalytic oxidizer, establish the operating limits according to subd. 3. b. 1) and 2) or 3. b. 3) and 4): 1) During the performance test, you shall monitor and record the temperature just before the catalyst bed and the temperature difference across the catalyst bed at least once every 15 minutes during each of the 3 test runs.
2) Use the data collected during the performance test to calculate and record the average temperature just before the catalyst bed and the average temperature difference across the catalyst bed maintained during the performance test. These are the minimum operating limits for your catalytic oxidizer.
3) As an alternative to monitoring the temperature difference across the catalyst bed, you may monitor the temperature at the inlet to the catalyst bed and implement a site-specific inspection and maintenance plan for your catalytic oxidizer as specified in subd. 3. b. 4). During the performance test, you shall monitor and record the temperature just before the catalyst bed at least once every 15 minutes during each of the 3 test runs. Use the data collected during the performance test to calculate and record the average temperature just before the catalyst bed during the performance test. This is the minimum operating limit for your catalytic oxidizer.
4) You shall develop and implement an inspection and maintenance plan for the catalytic oxidizers which you elect to monitor according to subd. 3. b. 3). The plan shall address, at a minimum, all of the following elements:
a) Annual sampling and analysis of the catalyst activity, i.e., conversion efficiency, following the manufacturer’s or catalyst supplier’s recommended procedures.
b) Monthly inspection of the oxidizer system including the burner assembly and fuel supply lines for problems.
c) Annual internal and monthly external visual inspection of the catalyst bed to check for channeling, abrasion and settling. If problems are found, you shall take corrective action consistent with the manufacturer’s recommendations and conduct a new performance test to determine destruction efficiency in accordance with this section.
NR 466.24(3)(f)1.1. You may assume your capture efficiency equals 100% if your capture system is a permanent total enclosure (PTE). You shall confirm that your capture system is a PTE by demonstrating that it meets the requirements of section 6 of Method 204 of 40 CFR part 51, Appendix M, incorporated by reference in s. NR 484.04 (9), and that all exhaust gases from the enclosure are delivered to a control device. NR 466.24(3)(f)2.2. You may determine capture efficiency according to the protocols for testing with temporary total enclosures that are specified in Methods 204 and 204A through F of 40 CFR part 51, Appendix M, incorporated by reference in s. NR 484.04 (9). You may exclude never-controlled work stations from such capture efficiency determinations. NR 466.24(3)(f)3.3. You may use any capture efficiency protocol and test methods that satisfy the criteria of either the data quality objective or the lower confidence limit approach as described in 40 CFR part 63, Subpart KK, Appendix A, incorporated by reference in s. NR 484.04 (24). You may exclude never-controlled work stations from capture efficiency determinations made under this subdivision. NR 466.24(3)(g)(g) Volatile matter retained in the coated web or otherwise not emitted to the atmosphere. You may choose to take into account the mass of volatile matter retained in the coated web after curing or drying or otherwise not emitted to the atmosphere when determining compliance with the emission standards in s. NR 466.23 (1). If you choose this option, you shall develop a testing protocol to determine the mass of volatile matter retained in the coated web or otherwise not emitted to the atmosphere and submit this protocol to the department for approval. You shall submit this protocol with your site-specific test plan under s. NR 460.06 (5). If you intend to take into account the mass of volatile matter retained in the coated web after curing or drying or otherwise not emitted to the atmosphere and demonstrate compliance according to s. NR 466.25 (3) (c), (d), (e) or (4), the test protocol you submit shall determine the mass of organic HAP retained in the coated web or otherwise not emitted to the atmosphere. Otherwise, compliance shall be shown using the volatile organic matter content as a surrogate for the HAP content of the coatings. NR 466.24(3)(h)(h) Control devices in series. If you use multiple control devices in series to comply with the emission standards in s. NR 466.23 (1), the performance test shall include, at a minimum, the inlet to the first control device in the series, the outlet of the last control device in the series, and all intermediate streams, such as gaseous exhaust to the atmosphere or a liquid stream from a recovery device, that are not subsequently treated by any of the control devices in the series.
