NR 440.525(4)(b)(b) Under s. NR 440.15 the “fixed capital cost of the new components” includes the fixed capital cost of all depreciable components (except components specified in par. (a) that are or will be replaced pursuant to all continuous programs of component replacement commenced within any 2-year period following August 24, 1982.
NR 440.525(5)(5)Monitoring of operations.
NR 440.525(5)(a)(a) The owner or operator subject to the provisions of this section shall install, calibrate, maintain and operate a monitoring device for the continuous measurement of the change in pressure of the gas stream through the scrubber for any affected facility using a wet scrubber emission control device. The monitoring device must be certified by the manufacturer to be accurate within ±250 pascals (±1 inch water) gauge pressure and must be calibrated on an annual basis in accordance with manufacturer’s instructions.
NR 440.525(5)(b)(b) The owner or operator subject to the provisions of this section shall install, calibrate, maintain and operate a monitoring device for the continuous measurement of the scrubbing liquid flow rate to a wet scrubber for any affected facility using any type of wet scrubbing emission control device. The monitoring device must be certified by the manufacturer to be accurate within ± 5% of design scrubbing liquid flow rate and must be calibrated on at least an annual basis in accordance with manufacturer’s instructions.
NR 440.525(6)(6)Recordkeeping and reporting requirements.
NR 440.525(6)(a)(a) The owner or operator subject to the provisions of this section shall conduct a performance test and submit to the department a written report of the results of the test as specified in s. NR 440.08 (1).
NR 440.525(6)(b)(b) During the initial performance test of a wet scrubber, and at least weekly thereafter, the owner or operator shall record the measurements of both the change in pressure of the gas stream across the scrubber and the scrubbing liquid flow rate.
NR 440.525(6)(c)(c) After the initial performance test of a wet scrubber, the owner or operator shall submit semiannual reports to the department of occurrences when the measurements of the scrubber pressure loss or gain or liquid flow rate differ by more than ±30% from the average obtained during the most recent performance test.
NR 440.525(7)(7)Test methods and procedures.
NR 440.525(7)(a)(a) In conducting the performance tests required in s. NR 440.08, the owner or operator shall use as reference methods and procedures the test methods in Appendix A of 40 CFR part 60, incorporated by reference in s. NR 440.17, or other methods and procedures as specified in this subsection, except as provided in s. NR 440.08 (2).
NR 440.525(7)(b)(b) The owner or operator shall determine compliance with the particulate matter standards sub. (3) as follows:
NR 440.525(7)(b)1.1. Method 5 or 17 shall be used to determine the particulate matter concentration. The sample volume for each run shall be at least 1.70 dscm (60 dscf). The sampling probe and filter holder of Method 5 may be operated without heaters if the gas stream being sampled is at ambient temperature. For gas streams above ambient temperature, the Method 5 sampling train shall be operated with a probe and filter temperature slightly above the effluent temperature, up to a maximum filter temperature of 121°C (250°F), in order to prevent water condensation on the filter.
NR 440.525(7)(b)2.2. Method 9 and the procedures in s. NR 440.11 shall be used to determine opacity from stack emissions and process fugitive emissions. The observer shall read opacity only when emissions are clearly identified as emanating solely from the affected facility being observed.
NR 440.525(7)(c)(c) To comply with sub. (6) (c) the owner or operator shall use the monitoring devices in sub. (5) (a) and (b) to determine the pressure loss of the gas stream through the scrubber and scrubbing liquid flow rate at any time during each particulate matter run, and the average of the 3 determinations shall be computed.

NR 440.53(1)(a)(a) The provisions of this section apply to the following affected facilities in an automobile or light-duty truck assembly plant: each prime coat operation, each guide coat operation and each topcoat operation.
NR 440.53(1)(b)(b) Exempt from the provisions of this section are operations used to coat plastic body components or all-plastic automobile or light-duty truck bodies on separate coating lines. The attachment of plastic body parts to a metal body before the body is coated does not cause the metal body coating operation to be exempted.
