NR 465.28(8)(a)2.2. 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 465.28(8)(b)1.a.a. During the performance test, 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. 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.

NR 465.28(8)(b)1.b.b. Monitor the temperature just before the catalyst bed and implement a site-specific inspection and maintenance plan for your catalytic oxidizer as specified in subd. 2. 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.

NR 465.28(8)(b)2.2. You shall develop and implement an inspection and maintenance plan for any catalytic oxidizer or oxidizers for which you elect to monitor according to subd. 1. b. The plan shall address, at a minimum, the following elements:

NR 465.28(8)(b)2.a.a. Annual sampling and analysis of the catalyst activity (i.e., conversion efficiency) following the manufacturer’s or catalyst supplier’s recommended procedures.

NR 465.28(8)(b)2.b.b. Monthly inspection of the oxidizer system including the burner assembly and fuel supply lines for problems and, as necessary, adjusting the equipment to assure proper air-to-fuel mixtures.

NR 465.28(8)(b)2.c.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 according to sub. (7).

NR 465.28(8)(c)(c) Carbon adsorbers. If your add-on control device is a carbon absorber, according to both of the following:

NR 465.28(8)(c)1.1. Monitor and record the total regeneration desorbing gas (e.g., steam or nitrogen) mass flow for each regeneration cycle and the carbon bed temperature after each carbon bed regeneration and cooling cycle for the regeneration cycle either immediately preceding or immediately following the performance test.

NR 465.28(8)(c)2.2. The operating limits for your carbon absorber are the minimum total desorbing gas mass flow recorded during the regeneration cycle and the maximum carbon bed temperature recorded after the cooling cycle.

NR 465.28(8)(d)1.1. During the performance test, monitor and record the condenser outlet (product side) gas temperature at least once every 15 minutes during each of the 3 test runs.

NR 465.28(8)(d)2.2. Use the data collected during the performance test to calculate and record the average condenser outlet (product side) gas temperature maintained during the performance test. This average condenser outlet gas temperature is the maximum operating limit for your condenser.

NR 465.28(8)(e)(e) Concentrators. If your add-on control device includes a concentrator, according to all of the following:

NR 465.28(8)(e)1.1. During the performance test, monitor and record the desorption concentrate stream gas temperature at least once every 15 minutes during each of the 3 runs of the performance test.

NR 465.28(8)(e)2.2. Use the data collected during the performance test to calculate and record the average temperature. This is the minimum operating limit for the desorption concentrate gas stream temperature.

NR 465.28(8)(e)3.3. During the performance test, monitor and record the pressure drop of the dilute stream across the concentrator at least once every 15 minutes during each of the 3 runs of the performance test.

NR 465.28(8)(e)4.4. Use the data collected during the performance test to calculate and record the average pressure drop. This is the maximum operating limit for the dilute stream across the concentrator.

NR 465.28(8)(f)2.2. For each capture device that is not part of a PTE that meets the criteria of sub. (6) (a), according to both of the following:

NR 465.28(8)(f)2.a.a. During the capture efficiency determination required by sub. (1) and described in subs. (5) and (6), monitor and record either the gas volumetric flow rate or the duct static pressure for each separate capture device in your emission capture system at least once every 15 minutes during each of the 3 test runs at a point in the duct between the capture device and the add-on control device inlet.

NR 465.28(8)(f)2.b.b. Calculate and record the average gas volumetric flow rate or duct static pressure for the 3 test runs for each capture device. This average gas volumetric flow rate or duct static pressure is the minimum operating limit for that specific capture device.

NR 465.28(9)(9) What are the requirements for continuous parameter monitoring system installation, operation and maintenance?.

NR 465.28(9)(a)1.1. You shall install, operate and maintain each CPMS according to the following requirements, except that subd. 1. a. and b. do not apply to capture system bypass lines and carbon adsorbers as specified in pars. (b) and (d):

NR 465.28(9)(a)1.a.a. The CPMS shall complete a minimum of one cycle of operation for each successive 15-minute period. You shall have a minimum of 4 equally spaced successive cycles of CPMS operation in one hour.
