If visible emission observations is the selected monitoring option, the owner or operator shall record visible emission observations from each exhaust stack for all consecutive 6-minute periods during the PM emission test according to the requirements of Method 9 in Appendix A to 40 CFR part 60, incorporated by reference in s. NR 484.04 (13).

NR 463.163(3)(a)(a) The owner or operator shall conduct performance tests to measure emissions of THC, D&F, HCl and PM at the outlet of the control device.

NR 463.163(3)(b)(b) If the scrap dryer, delacquering kiln or decoating kiln is subject to the alternative emission limits in s. NR 463.13 (5), the average afterburner operating temperature in each 3-hour block period shall be maintained at or above 760°C (1400°F) for the test.

NR 463.163(3)(c)(c) The owner or operator of a scrap dryer, delacquering kiln or decoating kiln subject to the alternative limits in s. NR 463.13 (5) shall submit a written certification in the notification of compliance status report containing the information required by s. NR 463.17 (2) (g).

NR 463.163(4)(a)(a) The owner or operator of a group 1 furnace that processes scrap other than clean charge materials with emissions controlled by a lime-injected fabric filter shall conduct performance tests to measure emissions of PM and D&F at the outlet of the control device and emissions of HCl at the outlet, for the emission limit, or the inlet and the outlet, for the percent reduction standard.

NR 463.163(4)(b)(b) The owner or operator of a group 1 furnace that processes only clean charge materials with emissions controlled by a lime-injected fabric filter shall conduct performance tests to measure emissions of PM at the outlet of the control device and emissions of HCl at the outlet, for the emission limit, or the inlet and the outlet, for the percent reduction standard.

NR 463.163(4)(c)(c) The owner or operator may choose to determine the rate of reactive flux addition to the group 1 furnace and assume, for the purposes of demonstrating compliance with the SAPU emission limit, that all reactive flux added to the group 1 furnace is emitted. Under these circumstances, the owner or operator is not required to conduct an emission test for HCl.

NR 463.163(4)(d)(d) The owner or operator of a sidewell group 1 furnace that conducts reactive fluxing, except for cover flux, in the hearth, or that conducts reactive fluxing in the sidewell at times when the level of molten metal falls below the top of the passage between the sidewell and the hearth, shall conduct the performance tests required by par. (a) or (b), to measure emissions from both the sidewell and the hearth.

NR 463.163(5)(a)(a) In the site-specific monitoring plan required by s. NR 463.15 (15), the owner or operator of a group 1 furnace, including a melting and holding furnace, without add-on air pollution control devices shall include data and information demonstrating compliance with the applicable emission limits.

NR 463.163(5)(b)(b) If the group 1 furnace processes material other than clean charge, the owner or operator shall conduct emission tests to measure emissions of PM, HCl and D&F at the furnace exhaust outlet.

NR 463.163(5)(c)(c) If the group 1 furnace processes only clean charge, the owner or operator shall conduct emission tests to simultaneously measure emissions of PM and HCl at the furnace exhaust outlet. A D&F test is not required. Each test shall be conducted while the group 1 furnace, including a melting and holding furnace, processes only clean charge.

NR 463.163(5)(d)(d) The owner or operator may choose to determine the rate of reactive flux addition to the group 1 furnace and assume, for the purposes of demonstrating compliance with the SAPU emission limit, that all reactive flux added to the group 1 furnace is emitted. Under these circumstances, the owner or operator is not required to conduct an emission test for HCl.

NR 463.163(6)(6) Sweat furnace. The owner or operator shall measure emissions of D&F from each sweat furnace at the outlet of the control device except that the owner or operator is not required to conduct a performance test to demonstrate compliance with the emission standard of s. NR 463.13 (6), provided that, on and after the compliance date established by s. NR 463.115, the owner or operator operates and maintains an afterburner with a design residence time of 0.8 seconds or greater and an operating temperature of 1600°F or greater.

NR 463.163(7)(7) Dross-only furnace. The owner or operator shall conduct a performance test to measure emissions of PM from each dross-only furnace at the outlet of each control device while the unit processes only dross and salt flux as the sole feedstock.

NR 463.163(8)(a)(a) The owner or operator of an in-line fluxer that uses reactive flux materials shall conduct a performance test to measure emissions of HCl and PM or otherwise demonstrate compliance in accordance with par. (b). If the in-line fluxer is equipped with an add-on control device, the emissions shall be measured at the outlet of the control device.

NR 463.163(8)(b)(b) The owner or operator may choose to limit the rate at which reactive chlorine flux is added to an in-line fluxer and assume, for the purposes of demonstrating compliance with the SAPU emission limit, that all chlorine in the reactive flux added to the in-line fluxer is emitted as HCl. Under these circumstances, the owner or operator is not required to conduct an emission test for HCl. If the owner or operator of any in-line flux box which has no ventilation ductwork manifolded to any outlet or emission control device chooses to demonstrate compliance with the emission limit for HCl by limiting use of reactive chlorine flux and assuming that all chlorine in the flux is emitted as HCl, compliance with the HCl limit shall also constitute compliance with the emission limit for PM, and no separate emission test for PM is required. In this case, the owner or operator of the unvented in-line flux box shall utilize the maximum permissible PM emission rate for the in-line flux boxes when determining the total emissions for any SAPU which includes the flux box.

NR 463.163(10)(10) Secondary aluminum processing unit. The owner or operator shall conduct performance tests as described in pars. (a) to (c). The results of the performance tests shall be used to establish emission rates in lb/ton of feed or charge for PM and HCl and mg TEQ/Mg of feed or charge for D&F emissions from each emission unit. These emission rates shall be used for compliance monitoring in the calculation of the 3-day, 24-hour rolling average emission rates using the equation in s. NR 463.15 (20). A performance test is required for:
