NR 440.74(5)(h)(h) Each owner or operator of an affected facility who demonstrates compliance as described in sub. (4) (b) shall follow the procedures described in par. (g) to establish a monitoring system for the total enclosure.

NR 440.74(6)(6) Test methods and procedures. Methods in Appendix A of 40 CFR part 60, incorporated by reference in s. NR 440.17, except as provided under s. NR 440.08 (2), shall be used to determine compliance as follows:

NR 440.74(6)(a)(a) Method 24 is used to determine the VOC content in coatings. If it is demonstrated to the satisfaction of the administrator that coating formulation data are equivalent to Method 24 results, formulation data may be used. In the event of any inconsistency between a Method 24 test and a facility’s formulation data, the Method 24 test will govern. For Method 24, the coating sample shall be a 1-liter sample collected in a 1-liter container at a point in the process where the sample will be representative of the coating applied to the substrate, that is, the sample shall include any dilution solvent or other VOC added during the manufacturing process. The container shall be tightly sealed immediately after the sample is collected. Any solvent or other VOC added after the sample is taken shall be measured and accounted for in the calculations that use Method 24 results.

NR 440.74(6)(b)(b) Method 25 shall be used to determine VOC concentrations from incinerator gas streams. Alternative Methods (18 or 25A), may be used as explained in the applicability section of Method 25 in cases where use of Method 25 is demonstrated to be technically infeasible. The owner or operator shall submit notice of the intended test method to the department for approval along with the notification of the performance test required under s. NR 440.08 (4). Except as indicated in subds. 1. and 2., the test shall consist of 3 separate runs, each lasting a minimum of 30 minutes.

NR 440.74(6)(b)1.1. When the method is to be used in the determination of the efficiency of a fixed-bed carbon adsorption system with a common exhaust stack for all the individual adsorber vessels pursuant to sub. (4) (a) 1., (b) or (c), the test shall consist of 3 separate runs, each coinciding with one or more complete system rotations through the adsorption cycles of all the individual adsorber vessels.

NR 440.74(6)(b)2.2. When the method is to be used in the determination of the efficiency of a fixed-bed carbon adsorption system with individual exhaust stacks for each adsorber vessel pursuant to sub. (4) (a) 2., (b) or (c), each adsorber vessel shall be tested individually. Each test shall consist of 3 separate runs, each coinciding with one or more complete adsorption cycles.

NR 440.74 NoteNote: Under 40 CFR 60.746, if, in the administrator’s judgment, an alternative means of emission limitation will achieve a reduction in emissions of VOC from any emission point subject to sub. (3) (c) at least equivalent to that required by sub. (3) (b) 2. or (3) (c), respectively, the administrator will publish in the Federal Register a notice permitting the use of the alternative means. The administrator may condition permission on requirements that may be necessary to ensure operation and maintenance to achieve the emission reduction as specified in sub. (3) (b) 2. or (3) (c), respectively. Any such notice shall be published only after public notice and an opportunity for a public hearing. Any person seeking permission under 40 CFR 60.746 shall submit to the administrator either results from an emission test that accurately collects and measures all VOC emissions from a given control device or an engineering evaluation that accurately determines such emissions.

NR 440.74(8)(a)(a) For each affected facility subject to the requirements of sub. (3) (b) and (c), the owner or operator shall submit the performance test data and results to the department as specified in s. NR 440.08 (1). In addition, the average values of the monitored parameters measured at least every 15 minutes and averaged over the period of the performance test shall be submitted with the results of all performance tests.

NR 440.74(8)(b)(b) Each owner or operator of an affected facility subject to the provisions specified in sub. (3) (c) 3. and claiming to use less than 130 Mg of VOC in the first year of operation and each owner or operator of an affected facility claiming to use less than 95 Mg of VOC in the first year of operation shall submit to the department a material flow chart indicating projected VOC use. The owner or operator shall also submit actual VOC use records at the end of the initial year.

NR 440.74(8)(c)(c) Each owner or operator of an affected facility subject to the provisions of sub. (3) (c) 3. and initially using less that 130 Mg of VOC per year and each owner or operator of an affected facility initially using less than 95 Mg of VOC per year shall:

NR 440.74(8)(d)(d) Each owner or operator of an affected facility demonstrating compliance by the methods described in sub. (4) (a) 1., 2., 4., (b) or (c) shall maintain records and submit quarterly reports to the department documenting the following:

NR 440.74(8)(d)1.1. For those affected facilities monitoring only the carbon adsorption system outlet concentration levels of organic compounds, the periods, during actual coating operations, specified in subd. 1. a. or b., as applicable.

NR 440.74(8)(d)1.a.a. For carbon adsorption systems with a common exhaust stack for all the individual adsorber vessels, all periods of 3 consecutive system rotations through the adsorption cycles of all the individual adsorber vessels during which the average value of the concentration level of organic compounds in the common outlet gas stream is more the 20% greater than the average value measured during the most recent performance test that demonstrated compliance.

NR 440.74(8)(d)1.b.b. For carbon adsorption systems with individual exhaust stacks for each adsorber vessel, all 3-day rolling averages for each adsorber vessel when the concentration level of organic compounds in the individual gas stream is more than 20% greater than the average value for that adsorber vessel measured during the most recent performance test that demonstrated compliance.

NR 440.74(8)(d)2.2. For those affected facilities monitoring both the carbon adsorption system inlet and outlet concentration levels of organic compounds, the periods, during actual coating operations, specified in subd. 2. a. or b., as applicable.

NR 440.74(8)(d)2.a.a. For carbon adsorption systems with a common exhaust stack for all the individual adsorber vessels, all periods of 3 consecutive adsorption cycles of all the individual adsorber vessels during which the average carbon adsorption system efficiency falls below the applicable level as follows:

1) For those affected facilities demonstrating compliance by the performance test method described in sub. (4) (a) 1., the value of E determined using Equation (1) during the most recent performance test that demonstrated compliance.
