NR 466.09(3)(b)(b) For the purpose of meeting the requirements of s. NR 466.07, the volatile matter and solids weight-fraction of each ink, coating, varnish, adhesive, primer, solvent, diluent, reducer, thinner and other material used in a product and packaging rotogravure or wide-web flexographic affected source shall be determined in accordance with one of the following procedures:

If the volatile matter or solids weight-fraction for any material cannot be determined using Method 24, the owner or operator shall submit an alternate method to the U.S. environmental protection agency for approval by the administrator.

NR 466.09(3)(c)(c) In the event of any inconsistency between the volatile matter or solids content of a material determined using formulation data as allowed under par.

NR 484.04, the applicable test method shall govern, unless after consultation, the owner or operator can demonstrate to the satisfaction of the department that the formulation data are correct.

NR 466.09(4)(4) Control device destruction efficiency. A performance test of a control device to determine destruction efficiency for the purpose of meeting the requirements of ss. NR 466.06 and 466.07, shall be conducted by the owner or operator in accordance with the following requirements:

NR 466.09(4)(a)(a) An initial performance test to establish the destruction efficiency of an oxidizer and the associated combustion zone temperature for a thermal oxidizer and the associated catalyst bed inlet temperature for a catalytic oxidizer shall be conducted and the data reduced in accordance with the following reference methods and procedure:

NR 466.09(4)(a)1.1. Use Method 1 or 1A in 40 CFR Part 60, Appendix A, incorporated by reference in s. NR 484.04, for sample and velocity traverses to determine sampling locations.

NR 466.09(4)(a)2.2. Use Method 2, 2A, 2C or 2D in 40 CFR Part 60, Appendix A, incorporated by reference in s. NR 484.04, to determine gas volumetric flow rate.

NR 466.09(4)(a)3.3. Use Method 3 in 40 CFR Part 60, Appendix A, incorporated by reference in s. NR 484.04, for gas analysis to determine dry molecular weight.

NR 466.09(4)(a)4.4. Use Method 4 in 40 CFR Part 60, Appendix A, incorporated by reference in s. NR 484.04, to determine stack gas moisture.

NR 466.09(4)(a)5.5. Perform Methods 2, 2A, 3 and 4 in 40 CFR Part 60, Appendix A, incorporated by reference in s. NR 484.04, as applicable, at least twice during each test period.

NR 466.09(4)(a)6.6. Use Method 25 in 40 CFR Part 60, Appendix A, incorporated by reference in s. NR 484.04, to determine organic volatile matter concentration, except as provided for in this subdivision. The owner or operator shall submit notice of the intended test method to the department for approval along with notice of the performance test required under s. NR 460.06 (2). The owner or operator may use Method 25A in 40 CFR Part 60, Appendix A, incorporated by reference in s. NR 484.04, if any of the following conditions are met:

NR 466.09(4)(a)6.a.a. An exhaust gas organic volatile matter concentration of 50 parts per million by volume (ppmv) or less is required to comply with the standards of s. NR 466.06 or 466.07.

NR 466.09(4)(a)6.b.b. The organic volatile matter concentration at the inlet to the control system and the required level of control are such to result in exhaust gas organic volatile matter concentrations of 50 ppmv or less.

NR 466.09(4)(a)6.c.c. Because of the high efficiency of the control device, the anticipated organic volatile matter concentration at the control device exhaust is 50 ppmv or less, regardless of inlet concentration.

NR 466.09(4)(a)7.7. Each performance test shall consist of 3 separate runs; each run conducted for at least one hour under the conditions that exist when the affected source is operating under normal representative operating conditions. Operations during periods of startup, shutdown and malfunction do not constitute representative conditions for the purpose of a performance test. For the purpose of determining organic volatile matter concentrations and mass flow rates, the average of results of all runs shall apply.

NR 466.09(4)(b)(b) The owner or operator shall record the process information necessary to determine the conditions of the performance test.

NR 466.09(4)(c)(c) For the purpose of determining the value of the oxidizer operating parameter that will demonstrate continuing compliance, the time-weighted average of the values recorded during the performance test shall be computed. For an oxidizer other than catalytic oxidizer, the owner or operator shall establish as the operating parameter the minimum combustion temperature. For a catalytic oxidizer, the owner or operator shall establish as the operating parameter the minimum gas temperature at the inlet to the catalyst bed. These minimum temperatures are the operating parameter values that demonstrate continuing compliance with the requirements of ss. NR 466.06 and 466.07.

NR 466.09(5)(5) Capture efficiency. Except as provided for in sub. (6), a performance test to determine the capture efficiency of each capture system venting organic emissions to a control device for the purpose of meeting the requirements of ss. NR 466.06 (4) (a) 2. and (b) and 466.07 (4) (a) 2., (5) (a), (7) (b) to (d) and (9) (b) and (c) shall be conducted by the owner or operator in accordance with the following procedures:

NR 466.09(5)(a)(a) For permanent total enclosures, capture efficiency shall be assumed as 100%. Method 204 in 40 CFR Part 51, Appendix M, incorporated by reference in s. NR 484.04, shall be used to confirm that an enclosure meets the requirements for permanent total enclosure.

NR 466.09(5)(b)(b) For temporary total enclosures, the capture efficiency shall be determined according to Method 204 and, as applicable, Methods 204A through 204F, in 40 CFR Part 51, Appendix M, incorporated by reference in s. NR 484.04. The owner or operator may exclude never-controlled work stations from the capture efficiency determinations.

NR 466.09(6)(6) Alternative capture efficiency. As an alternative to the procedures specified in sub. (5), an owner or operator required to conduct a capture efficiency test may use any capture efficiency protocol and test methods that satisfy the criteria of either the data quality objective (DQO) or the lower confidence limit (LCL) approach in 40 CFR Part 63, Subpart KK, Appendix A, incorporated by reference in s. NR 484.04. The owner or operator may exclude never-controlled work stations from the capture efficiency determinations.
