NR 440.43(6)(g)(g) All monitoring devices required under pars. (c) and (e) shall be checked for calibration annually in accordance with the procedures under s. NR 440.13 (2). NR 440.43(7)(a)(a) During any performance test required in s. NR 440.08, the owner or operator may not allow gaseous diluents to be added to the effluent gas stream after the fabric in an open pressurized fabric filter collector unless the total gas volume flow from the collector is accurately determined and considered in the determination of emissions. NR 440.43(7)(b)(b) 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 440.43(7)(c)(c) The owner or operator shall determine compliance with the particulate matter standards in sub. (3) as follows: NR 440.43(7)(c)1.1. The emission rate (E) of particulate matter shall be computed for each run using the following equation: where:
E is the emission rate of particulate matter, kg/MW-hr (lb/MW-hr)
N is the total number of exhaust streams at which emissions are quantified
Csi is the concentration of particulate matter from exhaust stream “i”, g/dscm (gr/dscf)
Qsdi is the volumetric flow rate of effluent gas from exhaust stream “i”, dscm/hr (dscf/hr)
P is the average furnace power input, MW
K is the conversion factor, 1000 g/kg (7000 gr/lb)
NR 440.43(7)(c)2.2. Method 5 shall be used to determine the particulate matter concentration (Csi) and volumetric flow rate (Qsdi) of the effluent gas, except that the heating systems specified in sections 2.1.2 and 2.1.6 of Method 5 are not to be used when the carbon monoxide content of the gas stream exceeds 10% by volume, dry basis. If a flare is used to comply with sub. (4), the sampling site shall be upstream of the flare. The sampling time shall include an integral number of furnace cycles. NR 440.43(7)(c)2.a.a. When sampling emissions from open electric submerged arc furnaces with wet scrubber control devices, sealed electric submerged arc furnaces or semienclosed electric arc furnaces, the sampling time and sample volume for each run shall be at least 60 minutes and 1.80 dscm (63.6 dscf). NR 440.43(7)(c)2.b.b. When sampling emissions from other types of installations, the sampling time and sample volume for each run shall be at least 200 minutes and 5.66 dscm (200 dscf). NR 440.43(7)(c)3.3. The measurement device of sub. (6) (b) shall be used to determine the average furnace power input (P) during each run. NR 440.43(7)(c)5.5. The emission rate correction factor, integrated sampling procedures of Method 3B shall be used to determine the CO concentration. The sample shall be taken simultaneously with each particulate matter sample. NR 440.43(7)(d)(d) During the particulate matter run, the maximum open hood area, in hoods with segmented or otherwise moveable sides, under which the process is expected to be operated and remain in compliance with all standards shall be recorded. Any future operation of the hooding system with open areas in excess of the maximum is not permitted. NR 440.43(7)(e)(e) To comply with sub. (6) (d) or (f), the owner or operator shall use the monitoring devices in sub. (6) (c) or (e) to make the required measurements as determined during the performance test.

NR 440.44(1)(a)(a) The provisions of this section are applicable to the following affected facilities in steel plants that produce carbon, alloy, or specialty steels: electric arc furnaces and dust-handling systems. NR 440.44(1)(b)(b) The provisions of this section apply to each affected facility identified under par. (a) that commenced construction, modification, or reconstruction after October 21, 1974 and on or before August 17, 1983. NR 440.44(2)(2) Definitions. As used in this section, terms not defined in this subsection have the meanings given in s. NR 440.02. NR 440.44(2)(a)(a) “Bag leak detection system” means a system that is capable of continuously monitoring relative particulate matter (dust) loadings in the exhaust of a baghouse to detect bag leaks and other conditions that result in increases in particulate loadings. A bag leak detection system includes an instrument that operates on triboelectric, electrodynamic, light scattering, light transmittance, or other effect to continuously monitor relative particulate matter loadings. NR 440.44(2)(am)(am) “Capture system” means the equipment (including ducts, hoods, fans, dampers, etc.) used to capture or transport particulate matter generated by an EAF to the air pollution control device.
